2018-May-01 UT 00:00-02:06 Ill=99% Aristarchus observed by Moore_P on 1977-7-1 *

     P Moore, Selsey, Sussex, UK, used a 5" x250 scope and between
     23:50UT on Jul 1st 1977 and 00:10UT on Jul 2nd 1977 observed
     Aristarchus. The south wall of the crater was reddish, extending 
     down to the outer south east wall (IAU). However seeing was no 
     better than III-IV and he was 99% sure that the colour was 
     spurious. His report was submitted only in case any other 
     observers reported something similar. ALPO/BAA weight=1.


2018-May-01 UT 00:43-00:58 Ill=99% Aristarchus observed by Mellor on 1978-5-22

     Aristarchus was not normal, but all the following features were: Mare 
     Crisium, Proclus, Sinus Iridium, Grimaldi, and Tycho. Observed by 
     Mellor and Fitton, UK. Observer notes that Aristarchus is brighter than 
     Tycho when normal. Estimated variation was 25%. However the Moon was 
     low and the Moon was yellow. Despite this the observer decided that the 
     effect was real. Cameron 2006 extension catalog ID=32 and weight=2.

2018-May-01 UT 20:15-22:04 Ill=96% Promontorium_Agarum observed by Moore_P on 1996-7-31

     On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300) 
     noticed a lack of detail in the Cape Agarum area - he would normally 
     have expected to have seen some craterlets. However he would not rate 
     this observation much because the seeing was only III and he does not 
     think that it was an obscuration. However just in case he wanted to 
     record this report in the archives. ALPO/BAA weight=1.


2018-May-01 UT 20:20-21:34 Ill=96% Aristarchus observed by Bartlett on 1954-11-12

     Aristarchus 1954 Nov 12 UTC 02:20-03:05 Observed by Bartlett 
     (Baltimore, MD, USA, S=5-6, T=3-4) "Blue-violet glare on EWBS & 
     whole length of E. wall. Suspected viol. tint on VA; uncertain @

2018-May-01 UT 21:26-23:23 Ill=96% Alhazen_Alpha observed by Daw on 1972-10-23

     Alphazen Alpha 1972 Oct 23 UT 22:10?-22:13? (Stoke-on-Trent, UK, 
     21cm Newtonian, x217, seeing very good). Flickering colours seen 
     on the north field of Alhazen Alpha mountain. Above UTs 
     estimated by the observer, but the duration of the effect was 3 
     minutes. Colouration centred on the hills that run north to 
     south between Mare Anguis and Mare Crisium. The colour 
     alternated from east to west about 2 or 3 times per second. The 
     colour was not apparent to the north or south, or indeed on any 
     other features. Telescope field of view moved, but effect stayed 
     in the same place on the Moon. Moon't terminator scanned for 15 
     minutes afterwards, but the effect did not recur. The colour 
     seen was mostly red, with a band of orange, and a strip of 
     yellow nearest the hills, the proportions being 6:2:1. The bands 
     seemed to arc up steep above the Moon's surface and flatten out 
     over the mare surface either side of the hill features. No 
     filters were used in the observation. Observer suspects some 
     kind of diffraction spectrum to explain the larger dispersion in 
     the red end of the spectrum. ALPO/BAA weight=3.

     On 1993 Sep 02 UT2250-23:30 C. Brook (Plymouth, UK, 70mm 
     refractor, x100, seeing=III) noted that Cleomedes A was 
     exceptionally bright and compared it with plate 4C in Henry 
     Hatfield's Atlas. He had noticed it was bright earlier in the 
     evening, but his attention was drawn to it at 22:50UT. By 
     23:07UT it was dimmer, with patches of cloud coming up and a 
     slight deterioration in seeing. By 22:30 UT the crater was no 
     longer exceptionally bright. The Cameron 2006 catalog ID=466 and

2018-May-02 UT 00:31-01:28 Ill=96% Aristarchus observed by Cook_MC on 1990-12-3

     On 1990 Dec 03 at UT23:00-01:30 M.C. Cook (Frimley, Surrey, UK) noticed 
     that the central peak of Aristarchus was quite bright and extended to a 
     circular region in the east in the crater "sprout" area - Cameron 
     suggests that this is Bartletts self defined EWBS area?. Beyond the rim 
     to the east was very bright. However no colour effect was seen in

2018-May-02 UT 23:30-01:27 Ill=91% Cleomedes observed by North_G on 1993-9-3

     Cleomedes Alpha 1993 Sep 03 UT2200-22:20 G. North (UK, 18.25" 
     reflector, x86 & x144) observed it to be a strikingly brilliant 
     'splodge' seen in the mostly shadow filled interior of 
     Cleomedes, and around this splodge was a faint halo extending 
     symetrically in an eastwards direction. The splodge was the 
     mountain Cleomedes Alpha. Strangely no shadow from the mountain 
     was seen to be cast onto the halo on the east. Observer alerted 
     other observers by phone, and upon returning to the scope found 
     that the splodge had faded in brightness and continued to fade 
     over the next hour as one would expect from a mountain at 
     sunset. Some heavy spurious colour was present. J. Cook & M. 
     Cook (Frimley, UK) observed at 22:20-22:25 and found the bright 
     splodge, but no halo. M. Cook re-observed later and confirmed 
     normal fading of splodge. Roscoe observed from 00:30UT next day, 
     but by that time Cleomedes Alpha had set and was no longer 
     visible in the shadow filled floor. S. Beaumont had observed 
     earlier at 20:00 but had recorded all as normal in Cleomedes.

2018-May-05 UT 23:17-00:49 Ill=69% Cabeus observed by LCROSS on 2009-10-9

     On 2009 Oct 09 UT11:00-11:04 NASA's LCROSS upper centaur stage, 
     followed 4 min later by the observation spacecraft, is due to impact 
     into a the crater Cabeus in the hope of kicking up some dust and 
     possible frozen volatiles. Note that this description is intended for 
     observers on the date of impact and it is doubtful that any new
     science could be achieved by re-observing the same area months
     after the impact. If you are observing on the date of impact, then 
     please observe around 11:00-11:04UT and ignore the predicted times in 
     the headings. However this report is included as techniqcally
     if something is seen it is a TLP, albeit man-made! For those observing 
     on the date in question here are a few observing tips to maximize 
     the science of your observations: (1) If you are imaging, then please 
     try to obtain images before the impact because you can then subtract 
     these from images taken during the impact and hence show up faint 
     changes that you might normally miss. (2) If you have a spare scope and 
     camera,use this to observe through filters such as UBVR or I, or if you
     have narrow band interference filters, try observing in
     say Hydrogen Alpha, Methane, OH, or indeed any volatile that you 
     might expect to see in a comet (the main source of water at the poles).
     (3) Please try checking the area long after the impact, just in
     case other effects might trigger a TLP. (4) Please go to some trouble 
     to ensure accurate timings- these will be essential in order to 
     understand the sequence of events - assuming any are seen. Timings can 
     be obtained using a short wave radio or via a GPS. Note that you should 
     always use UT or UTC. (5) Please send any observations that you make 
     into the upload section of the LCROSS campaign observers web site. If 
     you belong to an astronomical society e.g. BAA or ALPO, then do please 
     send copies of your observations to the Lunar Sections of your society 
     or club. (6) Finally this desription will be updated a day or two after 
     the planned impact.


2018-May-06 UT 00:04-01:28 Ill=69% Cabeus observed by Grego_P on 2009-9-9

     On 2009 Sep 09 UT23:31:43 P.Grego (St Dennis, Cornwall, UK, seeing II-
     III) suspected a flash south of Cabeus, just beyond the terminator.
     It was not bright, and lasted a fraction of a second. Thinks it might
     have been illusory as he saw some fainter flashes (cosmic rays?) 
     during that nights observing session. ALPO/BAA weight=1.

     x230) observed a glow 1-2 sec reappearance of Saturn's rings at a place 
     of ring's appearance on the dark limb. The observers attributed it to 
     Saturn and its rings. Cameron speculates that it might be due to gas or 
     dust at the lunar surface. Eye was attacted to the glow which 
     delineated the limb at a position angle of 210 deg at emersion, at

     noticed that the central peak(s) in Alphonsus were brightening 
     gradually. No effect was seen earlier at UT23:30-23:35. One presumes
     that the effect also occured between these two observing times?
     The observer suspects that this was not a TLP, but is uncertain.

     seen on a rim of Tycho, effect remained visible for only 2 
     minutes. Attempts to image it shortly afterwards failed as it 
     had finished by then" An REA-Brasil observational report.

2018-May-08 UT 00:25-01:27 Ill=51% Tycho observed by Cook_MC on 2009-9-11

     On 2009 Sep 11/12 UT23:28-00:00 M.C. Cook (Mundesley, UK, 90mm Questar,
     x80 and x190, seeing II and transparency moderate-poor) observed
     pink on the north west rim of Tycho and green-blue on the inner
     SW rim. No sign of colour elsewhere on the Moon except for the
     S-E rim of Plato that was red. The Moon was about 20 deg in altitude
     at the time. The effect had gone by the end of the observing period. 
     A simulation of spurious colour in different directions 
     was generated by the BAA Lunar Section and found to possibly account 
     for these colours, although there should have been some strong colours 
     seen elsewhere in Tycho and none were. The BAA/ALPO weight=2.

     On 1968 Dec 23 at UT 08:40-08:45 Osawa (Kyoto-Ken, Japan, 8" 
     reflector, x167 and x212, S=3-4, saw Taruntius crater (and a 
     wrinkle ridge) to be bright through a red filter. Cameron 
     mentions that this was during the Apollo 8 watch. The Cameron 
     1978 catalog ID=1108 and weight=3? The ALPO/BAA weight=2.


2018-May-18 UT 16:09-17:25 Ill=13% Aristarchus observed by Mackey on 1971-10-22

     Aristarchus 1971 Oct 22 UT 19:43-19:56 A.Mackay (Hatton, UK, 15cm 
     reflector, x50) observed a pale pink on the W(IAU?) half of 
     Aristarchus and a pale shade of blue on the E(IAU?) half. The 
     effect faded from 19:56UT onwards and had gone 2 minutes later. 
     No information on whether other craters exhibited this effect, 
     given. Burgess, who observed later did not see any colour. 
     ALPO/BAA weight=1.


2018-May-18 UT 16:09-16:52 Ill=13% Littrow observed by Madej_P on 1980-4-18

     On 1980 Apr 18 at UT 19:00-22:30 P. Madej (Huddersfield, UK) saw two 
     very bright flashes on the eastern edge of Littrow, spaced 40 seconds 
     apart. Ricketts observed blue flashes approximately 20-30 sec apart and 
     Foley saw faint blue. Cameron 2006 catalog ID=86 and weight=5. ALPO/BAA 
     weight=3.


2018-May-18 UT 16:14-17:25 Ill=13% Aristarchus observed by Foley_PW on 1980-4-18

     On 1980 Apr 16 at UT 20:00-22:20 P.W. Foley (Kent,UK, 12" reflector, 
     seeing II-III) found that Aristarchus could barely be seen. Therefore 
     it was not possible to take CED brightness measurements. Strangely 
     Cassini, Kepler, Plato and Mons Pico could be seen. However at 
     20:16 UT St Elmo fire-like flashes were seen coming from the interior 
     south east corner of Aristarchus at 20:16 UT and then the brightnesss 
     spread to fill the rest of he crater. Duration was about 5-20 sec 
     (Cameron comments: atmospheric effects?). The crater reached peak 
     brightness at 20:17UT (CED reading of 8). Foley comments that the 
     crater rim and area 16-24km around this (including Herodoyus) had a 
     translucent radiance. However at 20:25UT the brightness reduced 
     (including Herodotus) down to CED 3, however the blue radiance 
     remained. At 21:07UT Foley saw a star-like flash in the south east of 
     the floor (CED 3-4). Grimaldi was found to be of constant brightness by 
     comparison using the CED Brightness=2). At 20:20UT Amery (Reading, UK) 
     found Aristarchus to be a well visible circular fluorescent patch. At 
     20:40 Amery found the region between Aristarchus and Herodoutus was 
     glowing - appeared almost as a flare from Aristarchus and by 20:55UT 
     there was also a flare to the west of Aristarchus. At 20:27 Madej 
     (Huddersfield) detected only a slight glow from Aristarchus and the 
     region affected was small - indeed the glow had gone by 20:46. At 20:40 
     Ricketts detected a "continuous blue emission" - this had a cycle of 5-
     10 sec (Cameron comments: atmosphere?). Saxton (Leeds, UK) detected at 
     20:42 "translucent effects and variations" at 20:42 noticed a star-like 
     point. At 19:00-21:40 M. Price (Camberley, UK) decided that Aristarchus 
     was fainter in brightness than normal. Peters observed a faint nebulous 
     spot at at 20:25-21:00 that changed in brightness in an irregular way.

     On 1969 Jan 22 at UT 00:10-00:30 Kilburn (England, UK, 6" reflector 
     x192, English Moon Blink device) observed a colour blink on the outer 
     east wall of Gassendi. Cameron says: "in dark!". The Cameron 1978

2018-May-19 UT 16:10-17:27 Ill=23% Mutus_F observed by Spellman_R on 2005-1-15

     On 2005 Jan 15 at UT 01:25 R. Spellman (Los Angeles, CA, USA, 8" 
     reflector) observed 4 bright points of light on the crater Mutus F? - 
     see Rukl Atlas page 175, chart 74. If his identification of the crater 
     was correct then he could see no structures in the crater that would 
     yield this effect. It could well be that the 4 bright points are just 4 
     high peaks on the rim catching the first rays of the Sun. The ALPO/BAA 
     weight=1.


2018-May-19 UT 16:11-18:06 Ill=23% Atlas observed by Osawa on 1968-12-24

     Atlas 1968 Dec 24 at UT 09:15-10:45 Osawa (Kyoto-Ken, Japan, 8" 
     reflector, 9mm Ortho, Seeing=5, later worse) saw a slight 
     brownish hue on the northern shadowy bed in the crater. It was 
     difficult to see the difference between the glow and chromatic 
     aberation of the eyepiece. The tint never showed up in filters. 
     The ALPO/BAA weight=1.


2018-May-19 UT 16:33-18:23 Ill=23% Aristarchus observed by Madej_P on 1980-4-19

     On 1980 Apr 19 at UT 20:37-20:49) P. Madej (Huddersfield, UK, 
     77mm refractor, x83 and x111) at 20:37 UT saw a slight glow at 
     x83, quite small in size. At 20:46UT no glow was seen at x83. 
     At 20:49 a slight glow seen again, but unclear and 
     illdefined - appeared larger in area at x111. Observatons 
     ceased at 21:56 dues to clid. ALPO/BAA weight=1. 


2018-May-19 UT 16:36-18:23 Ill=23% Taruntius observed by Buczynski_DG on 1980-4-19

     On 1980 Apr 19 at UT20:30-22:59. The following is quoted from the 
     Cameron 2006 catalog.... "(Buczynski) alerted by colleague (Greenwood) 
     who used filters W15 (IR), W25 (red), W44A (blue), & W58 (UV) and had 
     located a possible blink in it. (Bucz) used W15, W44A & W25. C.P was 
     very bright in W25 (red), dull but vis. In W44A (blue) & floor was 
     noticibly darker in W44A than in W25. Bright cp vis. In W15 & floor was 
     of a light shade. Other craters checked for color, none found. In 44A 
     floor lost some definition (gas?). Sketches from Bucz. & Greenwood. 
     (Pedler) at 2140, floor area around cp was seen in white & red as 
     normal but blink was vis in white, darker in blue. Checks of other 
     features were negative. (Amery) small dark center & small dark area - 
     not shadow - under S wall. N wall obscured by dark area extending N 
     onto surrounding mare. (normal?) which was difficult to focus (gas?). 
     At 2155 N wall now sharper & dark area less intense. Craterlet Cameron 
     in N wall clearly seen which was invisible 1/2 h earlier. (Saxton) 
     whole crater flashed and blinked at 2155. Could see detail in brighter 
     W 1/2 of crater - not seen earlier. At 2205 seeing poor, at 2215 it was 
     normal. (Blair) at 2155 used red & blue filters & in blue it was darker
     than in red. W. wall not well defined. (J. Cook) saw spurious color on

2018-May-20 UT 16:11-16:31 Ill=33% Moon observed by Hirst on 1879-10-20

     In 1879 Oct 20 UT 23:00 (Local time Oct 21 9AM) Hirst (Blue Mountains, 
     NSW, Australia) saw a large part of the Moon covered with a dark shadow 
     that was as dark as the Earth's shadow would have been if there had 
     been an eclipse. Cameron says that this is a confirmed observation. 
     Note that the Moon was just before first quarter. The Cameron 1978 
     catalog ID=215 and the weight=4. The ALPO/BAA weight=3.


2018-May-20 UT 16:11-17:18 Ill=33% Aristarchus observed by Lagunas on 1969-11-15

     On 1969 Nov 15 at UT 02:20-03:20 Lagunas (Santiago, Chile, 10" 
     reflector) observed some brightenings in Aristarchus during the Apollo 
     12 watch. The Cameron 1978 catalog ID=1209 and weight=0. The ALPO/BAA 
     weight=1.


2018-May-20 UT 16:11-17:14 Ill=33% Aristarchus observed by Foley_PW on 1980-4-20

     On 1980 Apr 20 at UT 19:25-23:43 P.W. Foley (Kent, UK, 10" reflector, 
     seeing II-III) found that Aristarchus was very bright in Earthshine 
     (also found on the photographs that he took), giving off a blue 
     "incadescence", the CED brightness reading was 5. Occasionally Foley 
     could see a star-like point in the south east corner. For comparison in 
     brightness he used highland terrain near to Grimaldi (CED=2). By 
     comparison, Buczynski and Lord, could not see Aristarchus. Earlier, 
     Geenwood saw the crater easily as a star-like point with a diffuse 
     exterior glow. Cameron says thyat this was confirmed by Buczynski and 
     Lord (?). At 20:35UT Amery decided that Aristarchus looked brighter 
     than normal. Pedler though described the crater as "small dim nebulous 
     blue or blue-green" that was invisible by 20:27UT. At 20:28-22:01 Blair 
     could not detect Aristarchus, nor could J-H Robinson at 20:40UT though 
     he did see it at 20:55UT as both diffuse and blue. Ricketts detected a 
     blow glow with irregularly spaced flashes of roughly 5-10 sec apart. 
     Cook's at Frimley, UK, saw no features in Earthshine. Cameron 2006 
     catalog ID=88 and weight=4. ALPO/BAA weight=2.

     On 1980 Apr 20 at UT20:05-21:02 J.D. Cook (Frimley, UK, 12" reflector, 
     x60, seeing III-IV) at the start of this session found some bright 
     spots in the area of Copernicus, and at 21:02 detected some flashes in 
     this region. Cameron 2006 catalog ID=88 and weight=1. ALPO/BAA 
     weight=1.


2018-May-20 UT 16:11-17:34 Ill=33% Piccolomini observed by Cook_MC on 1980-4-20

     On 1980 Apr 20 at UT 19:45-22:45 M.C.Cook (Frimley, UK) - colour 
     (probably spurious) seen on Piccolomini. Cameron 2006 catalog ID=88 and 
     weight=4. ALPO/BAA weight=1.


2018-May-20 UT 16:21-18:16 Ill=33% Grimaldi observed by Price_M on 1980-4-20

     On 1980 Apr 20 at UT20:27 M.Price (Camberley, UK) saw a flash in the 
     Grimaldi-Aristarchus area. Cameron 2006 catalog TLP ID=88 and weight=4. 
     ALPO/BAA weight=2.


2018-May-20 UT 17:05-19:01 Ill=34% Fracastorius observed by Robinson_JH on 1980-4-20

     On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teighmouth, UK, 10.5" 
     reflector, x180) found, using a Moon Blink device, evidence of colour 
     on the flor patches of Fracastorius crater, brighter in blue than in 
     red. Also the floor to center varied in brightness in blue and in red. 
     Peters observed in white light and found the south east-south wall had 
     a slight orange cast and when a Moon blink was used it was less bright 
     in blue than in red light. M. Cook found spurious colour on the south 
     rim and also on Mons Pico. There was a colour blink reaction on the 
     southeast floor of Fracastorius - this was both faint and blurred and 
     not seen in white light. A.C Cook detected the permanent blink in the 
     south east floor of the crater at 21:47 and a fainter one in the north 
     west (marginally brighter in red than in blue). J.D. Cook found no 
     colour with the Moon blink device. 21:22-22:10 P.W. Foley got a strong 
     colour reaction with the Moon Blink device - brighter in red than in 
     blue and detected a pink colour visually on the south east wall 22:10-
     22:45 (this did not give a blink effect though). Cameron 2006 catalog 
     ID=88 and weight=4. ALPO/BAA weight=2.


2018-May-20 UT 17:31-19:14 Ill=34% Petavius observed by Blair_G on 1980-4-20

     On 1980 Apr 20 at UT21:38-21:50, Blair of Renfrewshire, Scotland (used 
     an 8" reflector and seeing=III) saw three patches in Petavius and they 
     could still be seen 7 minutes later. At 21:50UT he used a filter and 
     found the "northern one was brighter in blue, the southern one was 
     brighter in red and the central one was the same shad ein both 
     filters." Cameron comments that the central patch was a permananent 
     one. She then goes onto say that the crater is described as having dark 
     patches that are opposite to what one would expect from Fitton's theory 
     applied to dark features. Cameron 2006 extension catalog ID=88 and 
     weight=4. ALPO/BAA weight=3.

2018-May-21 UT 16:12-17:37 Ill=45% Censorinus observed by Holmes_D on 1988-11-15

     On 1988 Nov 15 UT 19:15 Holmes (Rockdale, UK, 215mm Newtonian) noticed 
     the Censorinus apron (just east of the crater and including the rim) 
     was fuzzy but the crater was clear - a sketch was provided. A BAA Lunar

2018-May-21 UT 16:12-16:32 Ill=45% Apianus_D observed by Power_F on 2011-10-3

     Apianus D On 2011 Oct 03 UT 21:00-21:20 F. Power (Meath, 
     Ireland, 11" SCT) observed changing colours (blue, white, and 
     red) on the inner western rim of this crater. He changed 
     eyepieces and moved the scope around to look at dufferent parts 
     of the Moon, but nowhere else exhibited anything similar. As 
     another test he asked his wife to have a look without telling 
     her what he was seeing. She confirmed the same effect. 5 digital 
     camera images had been taken. Most of these were out of focus 
     and the first one was saturated, however one of them showed a 
     approximately 35 km long, by 11 km wide (at the north) lopsided 
     carrot shaped orange colour to the western rim of Apianus D. No 
     similar strong colour could be seen anywhere else on the image, 
     nor on the other 4 images. This TLP is being given an ALPO/BAA 
     weight of 1 as the Moon was low, but an image taken looks 
     interesting.


2018-May-21 UT 16:27-18:21 Ill=45% Torricelli_B observed by Braga_R on 2001-4-29

     On 2001 Apr 29 at UT 20:50 R. Braga (Italy) reported that without any 
     filter, the brightness of the east wall of Torricelli B was halfway 
     Torricelli C (faintest) and Moltke (brightest). By insering a Wratten 
     25 red filter though, the crater was slightly more evident. However 
     using a blue Wratten 39A filter, the crater vanished completely, whilst 
     Toricelli C remained. The ALPO/BAA weight=3. 


2018-May-21 UT 19:37-19:58 Ill=46% Aristarchus observed by Butler_FC on 1981-3-12

     On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a 
     10" reflector at 32-64x) noticed that Aristarchus was not 
     visible, although the Earthshine was very obvious. Foley (of 
     Kent, UK, and using  12" reflector) noticed that the crater was 
     only just visible but Plato could definitely be seen. Cameron's 
     2006 TLP extension catalog ID=125 and weight=0. ALPO/BAA 
     weight=2.

2018-May-22 UT 16:13-16:15 Ill=56% Mons_Piton observed by Horne_P on 1983-3-21

     On 1983 Mar 21 at UT 21:05-22:00 P. Horne and J. Horne (Hertz, England, 
     UK, 11" reflector, x180 and x330) found that Mons Piton (totally 
     illuminated and brightest feature on the Moon - but no variability) was 
     brighter than Aristarchus (would have been if it had been in sunlight)
     and the mountain was contained within a circular illuminated patch. 
     "Brilliant white and no shadow. Size ~16km." There was no details 
     visible but the adjacent features had distinct shadows. Hutton was also 
     observing. Foley examined the photographs and believes that they are 
     inconclusive. D. Mansbridge was photographing the Moon at 19:30UT and 
     detects Piton but it is not bright. However in a photograph taken by D. 
     Mansbrdige and 20:30UT the mountain is much brighter than any other 
     sunward facing slopses on the northern part of the Moon's terminator. 
     R. Mosley had been observing earlier at 18:10-19:40 and although 
     finding the mountain to be shining briliantly beyond the terminator, he 
     also comments that this is normal. Cameron though has seen the 
     photographs taken and thinks it might be a real TLP. The Cameron 2006 
     catalog ID=208 and weight=5. The ALPO/BAA weight=2.

     On 1984 Apr 08 UT 19:50 Mobberley (14" reflector, x194, seeing 
     III-IV, Transparency Fair-Poor, Cockfield, UK) found that 
     Torricelli B's shadow was 1/2 the way across the floor, which 
     was normal, but that there was a very dar grey/brown shroud 
     around the carter, out to several radii. 
     The ALPO/BAA weight=1.


2018-May-22 UT 16:13-16:37 Ill=56% Censorinus observed by Cook_MC on 1988-11-16

     On 1988 Nov 16 at UT 18:20 M.C. Cook (Frimley, UK) observed that a ray 
     north east of censorinus appeared to be very diffuse and this did not 
     change during the observation. This was odd because proclus ray 
     material remained clear. The apron material of Censorinus was diffuse 
     E-W and the northern part was dull, but not fuzzy. The Cameron 2006 
     catalog ID=340 and the weight=3. The ALPO/BAA weight=2.


2018-May-22 UT 16:13-16:37 Ill=56% Torricelli_B observed by Cook_MC on 1988-11-16

     On 1988 Nov 16 at UT 18:20 M.C. Cook (Frimley, UK) observed that 
     Torricelli B changed in brightness (at times), but thinks that this was 
     due to atmospheric transparency. The Cameron 2006 catalog ID=340 and 
     the weight=3. The ALPO/BAA weight=1.


2018-May-22 UT 16:20-18:17 Ill=56% SE_Limb observed by Rohslberger_R on 1980-4-22

     On 1980 Apr 22 at UT20:30 R.Rohslberger (Hittfield, (near Hamburg) West 
     Germany, 8" reflector, x170 25mm occular used, 300mm focal length?) 
     took some photographs using projection. One of these recorded an 
     apparent "ejecta curtain". Cameron considered lens flare, but the other 
     photographs did not show this. If real then the plume was at a height 
     of ~40km and the ray was ~130km. Cameron concludes that this was an 
     impact photograph. The Cameron 2006 catalog ID=90 and the weight=5. The 
     ALPO/BAA weight=3.


2018-May-22 UT 16:36-18:33 Ill=56% Alphonsus observed by Lenham_AP on 1952-11-24

     Alphonsus 1952 Nov 24 UT 18:00 A.P. Lenham (Swindon, UK, 3-
     inch efractor x120) noted that the usual dark spots were not 
     visible, but floor ridges and craterlets were surperbly seen. 
     This may not be a TLP but has been given a TLP category as it 
     is a curious appearance and needs to be verified on a repeat 
     repeat illumination apeparance. ALPO/BAA weight=1.


2018-May-22 UT 17:21-19:15 Ill=56% W_Limb observed by Miles_H on 1987-1-7

     On 1987 Jan 07 at UT19:10-20:30 H.Miles of Cornwall, UK saw two bright 
     patches were seen in Earthshine at clock positions of 4 (this patch was 
     defined by the dark limb and the brightness faded inwards to the disk, 
     over a short distance. "Centred at 60 deg along the limb from the north 
     - a sketch showed approximately 10-15 deg along it") and 5:30 (this 
     second patch was smaller and not so bright as the first patch - it was 
     west of the north pole. P. Foley (Kent, UK) also detcted the patches 
     and said that one was not far from the sunrise terminator. 
     The Cameron 2006 Extension catalog gives this TLP an ID of 291 and a 
     weight of 2. The ALPO/BAA weight=2.


2018-May-22 UT 18:47-20:37 Ill=57% Alphonsus observed by Hopp on 1972-9-15

     Alphonsus 1972 Sep 15 UTC 18:48-18:56 Observed by Hopp (13.25E, 52.5N, 
     75mm refractor) "Diffuse white to blue area within the crater - not 
     sure" T=4, S=4. Ref: Hilbrecht & Kuveler Moon & Planets (1984) Vol 30, 
     pp53-61.


2018-May-22 UT 19:35-20:37 Ill=57% Werner observed by Lippert_RM on 1953-9-16

     On 1953 Sep 16 UT03:00 R.M. Lippert (San Diego, CA, USA, 20cm 
     Cassegrain reflector, x90)saw a bright magnitude 1 flash on the 
     Moon, that was probably on the east rim of Werner(?) crater. It 
     is unclear if the observer meant it was really magnitude 1, or 
     was what a magnitude 1 star would have looked like. The flash 
     was yellow-orange in colour. Observation described in the 
     "Observations and Comments" column in the December, 1953 
     Strolling Astronomer (Vol. 7, No. 12), on page 170. The ALPO/BAA 
     weight=3.


2018-May-22 UT 19:59-20:37 Ill=57% Messier observed by Klein_HJ on 1878-11-2

     Messier 1878 Nov 02 UT 20:00? Observed by Kleis (Cologne, Germany, 6" 
     refractor?) "Shaped like a half moon with E. edge missing. Appeared 
     diffuse. Messier A was sharp & completely defined. Was sure there was 
     fog there. Next day same appear. Shadow was diffused before noon, Mess. 
     A is more yellow after noon, greener near Mess. A noon, both are same 
     color." NASA catalog weight=4 (very high). NASA catalog ID #206.


2018-May-22 UT 20:05-20:37 Ill=57% Proclus observed by Darling_D on 1989-12-5

     On 1989 Dec 05 D. Darling of Sun Praire, WI, USA, saw two dark spots on 
     the SE floor of Proclus. The first dark spot was seen through  3" 
     refractor and then also through a 12.5" reflector (35x and 154x). 
     Seeing was S=10 and T=5. He noticed that at 23:00UT the wall spot was 
     less well defined. Darling also comments that he observed reflecting 
     glint, almost as if from a glass surface - he had not seen this effect 
     before. A telephone alert was issued and Caruso verified the spots. 
     Cameron comments that the spots were not shadows because the Sun was at 
     an altitude of 52 deg at Proclus at the time and she states that the 
     steepest slope ever mesured on the Moon was 52 deg and not inside 
     Proclus. Other observers observing were: Weier (6.5" refractor x284 and 
     S=3/10), Caruso (8" reflector x100), and Cameron. The Cameron 2006 
     catalog extesnion ID was 382 and the weight=1. ALPO/BAA weight=3.


2018-May-22 UT 20:21-20:37 Ill=57% Dawes observed by Thornton_FH on 1948-2-17

     Dawes 1948 Feb 17 UT  19:30 Observed by Thornton (Northwick, England, 
     18" reflector) "Did not see c.p. saw cleft-like streaks from SW crest 
     to E, shadow." NASA catalog weight=3 (average). NASA catalog ID #501.


2018-May-22 UT 20:31-20:37 Ill=57% Curtis observed by Williams_AS on 1882-8-21

     Williams of the UK, on 1882 Aug 21 at 19:30UT (Moon's age 7.9 
     days) noticed a spot at least half as bright, and as large as 
     Picard, near to Picard crater. This observation was reported 
     in the Astronomical Register of the Royal Astronomical Society 
     and is not included in the Cameron catalogs. It is one of many 
     measurements of the brightness of this spot for different 
     illumination angles and is one of three outlying brightness 
     points spotted on a graph by Willaims. The ALPO/BAA weight=3.


2018-May-22 UT 20:31-20:37 Ill=57% Pickering observed by Collier on 1971-1-4

     Pickering 1971 Jan 04 UTC 20:29-20:37 Observed by Collier (London, 
     England) "Between Saunder and Rhaeticus, apparently coming from Pick. 
     After 2027h it dimished with extraordinary swiftness, like a light goes 
     out. (experienced observer)" NASA catalog weight=?. NASA catalog ID #
     1281. Note that this crater was previously called E.C. Pickering before 
     the IAU renamed some craters.


2018-May-23 UT 16:13-17:42 Ill=67% Alphonsus observed by Lenham_AP on 1952-11-25

     Alphonsus 1952 Nov 25 UT 17:15 A.P. Lenham (Swindon, UK, 3-
     inch refractor) noted that the usual dark spots were not 
     visible. This may not be a TLP but has been given a TLP 
     category as it is a curious appearance and needs to be 
     verified on a repeat repeat illumination apeparance. ALPO/BAA 
     weight=1.


2018-May-23 UT 16:13-16:57 Ill=67% Eratosthenes observed by Lenham_AP on 1952-11-25

     Eratosthenes 1952 Nov 25 UT 16:30 A.P. Lenham (Swindon, UK, 3-
     inch refractor x150, Definition Good) noted that there was 
     faint/slightly bright detail inside the interior shadow - 
     observer comments "presumably peaks of central mountains & W. 
     Wall ridge, but very faint" - however this is worth checking 
     out. ALPO/BAA weight=1.


2018-May-23 UT 16:13-18:10 Ill=67% Pallas observed by Stuart_L on 1953-11-15

     Pallas-Schroter 1953 Nov 13 UTC 02:00 Observed by L.Stuart (USA) 
     "Saw and photographed a bright spot on term. between these two 
     craters. Used Kodak 103aF3." NASA catalog weight=5 and catalog 
     ID #559. ALPO/BAA weight=5.


2018-May-23 UT 16:13-17:32 Ill=67% Eratosthenes observed by Abel_P on 2009-11-25

     On 2009 Nov 25 UT18:42-21:03 P.Abel, T.Little and C.North (Selsey, UK, 
     15" reflector, seeing II-III, transparency very good), all saw visually 
     a brownish tinge on the north west rim of Eratosthenes crater. P.Abel 
     made a sketch and T.Little took some high resolution CCD images, some 
     of which were through coloured filters. Checks were made for spurious 
     colour, but none was seen elsewhere on the Moon. The eyepiece was 
     changed but this made no difference. M.C.Cook (Mundesley) was observing 
     with a smaller scope at the same time, but saw no colour, however 
     observing conditions were worse. W.Leatherbarrow (Sheffield, UK) was 
     observing with a instrumenet mid way in size, and saw a brownish tinge 
     in the NW rim area, but saw a similar colour elsewhere and put this 
     down to spurious colour. Normally multiple observers seeing the same 
     thing would result in a weight of 4, however as this was only observers 
     at Selsey and some of the evidence contradicts, I am allocating an 
     ALPO/BAA weight=3.


2018-May-23 UT 16:19-18:12 Ill=67% Eratosthenes observed by Galdies_C on 2012-8-25

     On 2012 Aug 25 UT1944-1952 Eratosthenes crater was imaged by C. 
     Galdies (Malta,Nexstar 8SE, Philips SPC 900NC camera). 4 
     Registaxed images were produced covering 19:45, 19:48, 19:49, 
     and 19:51. All but the first image, once first order spurious 
     colour had been removed, showed orange on the shaded terraces on 
     the western illuminated rim (similar to what Paul Abel and 
     others saw in 2009, albeit just confined to the NW rim), and the 
     interior floor shadow was slightly smaller in red light. However 
     orange colour was also seen on the eastern side of mountains to 
     the south of the crater, which infers that the spurios colour 
     removal did not fully acomplish its main goal. The effects were 
     not caused by the registax software as the orange colour is 
     visible on individual images. Although probably the colour is 
     not lunar in orgin, its explanation is not fully explaianed, 
     therfore an ALPO/BAA weight of 1 is used for now.


2018-May-23 UT 17:07-19:04 Ill=67% Aristarchus observed by Loocks on 1969-11-18

     On 1969 Nov 18 at UT 04:22 Loocks (Valparaiso, Chile, 12" reflector) 
     observed a flash of light of magnitude 12. Cameron speculates a meteor 
     and mentions the apollo 12 watch. The Cameron 1978 catalog ID=1214 and 
     weight=1. The ALPO/BAA weight=1.


2018-May-23 UT 17:21-19:16 Ill=67% N_Pole observed by Harris on 1912-1-28

     North (?) (left) Cusp 1912 Jan 28 UT 00:00 (27th 20:00 L.T.) Observed 
     by Harris (Philadelphia? Pennsylvania?, naked eye?): Intensely black 
     curved object 400x240km, shaped like a "crow". Cameron 1978 weight=1 
     (very low) and ID=334. ALPO/BAA weight=1.


2018-May-23 UT 17:41-19:37 Ill=67% Eratosthenes observed by Longshaw_N on 2017-5-4

     Eratosthenes: On 2017 May 04 UT 21:50-22:10 N. Longshaw (BAA, 
     UK, 78mm APO refractor, x125 & x175, seeing II-III, 
     transparency Good). A brownish (orange) tint was seen on the 
     inner NW wall light terraces - this was immediately obvious 
     when first looking at the crater, but as time progressed the 
     effect became less bright. Other craters were checked for 
     similar coloured tints, but none were seen elsewhere on the 
     Moon. UAI observers in Italy (F. Taggogna & A. Tonon) had been 
     imaging the region in colour 17:57-21:47, but their images do 
     not show any colour on the inner NW rim terraces, the their 
     last image is 3 min before Longshaw saw the colour. The 
     ALPO/BAA weight=2.


2018-May-23 UT 17:56-19:52 Ill=67% Eratosthenes observed by Hill_H on 1947-1-30

     Eratosthenes 1947 Jan 30 Mean Col. 16deg. Observed by Hill (UK) "Main 
     peak of massive central mountain group appeared to be in a shadowless 
     having regard to it's claimed height of 6,600 ft. The whole of the 
     floor to the west should have still been in darkness. Instead 
     immediately to the west was a dark (intensity 1.5-2) region extending 
     almost to the foot of the bright inner wall and very diffuse in 
     outline. The observation could not be followed through due to 
     increasing cloud, but on the following night all was normal."


2018-May-23 UT 19:16-21:10 Ill=68% Aristarchus observed by Tempel on 1886-6-10

     On 1886 Jun 10 at UT 21:00 (estimated) Tempel of Germany, saw a star-
     like light (Cameron comments that the reference in the Middlehurst 
     catalog is wrong). Cameron 1978 catalog ID= and weight=4. ALPO/BAA 
     weight=3.


2018-May-23 UT 20:49-21:10 Ill=68% Proclus observed by Cook_MC on 1981-5-12

     On 1981 May 12 UT 22:00? M.C. Cook (Frimley, UK and using a 12" 
     reflector), noticed that Censorinus was very bright, fuzzy and 
     occasionally brighter than Proclus. However both Foley (Kent, UK) and 
     Amery (Reading, UK) using a C.E.D. found that Proclus was brighter than 
     Censorinus as it had been during April and May 1981. However Chapman 
     obtained the reverse of this. Cameron 2006 extension catalog ID=138 and 
     weught=3. ALPO/BAA weight=2.


2018-May-23 UT 20:50-21:10 Ill=68% Proclus observed by Darling_D on 1989-12-6

     On 1989 Dec 06 at 23:09-23:34UT D. Darling of Sun Praire, WI, USA (3" 
     refractor x36 and x90, and then a 12.5" reflector at x64, S=7/10 and T=
     4, saw dark spots in Proclus (not as dark as those from 5th Dec 1989). 
     Two telescopes were used and the bigger of these revealed some shading 
     on the floor of Proclus approximately a third as intense as he had seen 
     the previous night. A sketch was made. The TLP finished by 22:34UT. 
     Cameron comments that the dark patches could not be due to shadow as 
     the altitude of the Sun was too high at proclus. The Cameron 2006 
     extension catalog ID=383 and the weight=0. The ALPO/BAA weight=2.


2018-May-24 UT 16:14-17:16 Ill=77% Eratosthenes observed by Haas_W on 1936-10-25

     reflector) saw small bright spots on the floor of Eratosthenes, 
     (Pickering's atlas 9A, col. 30deg, shows no spots - according to 
     Cameron). Cameron 1978 catalog TLP=417 and weight=4. ALPO/BAA

     On 1980 Apr 24 at 23:35UT Marco Petek (Porto Alegre, Brazil, 
     using a 7.5" refractor noticed that the center of Plato was 
     bright and opaque and the observer thought it was similar in 
     appearance to Linne. A sketch was made and two other observers 
     confirmed the appearance. Cameron mentions that Petek is an 
     experienced observer. Cameron 2006 catalog extension TLP ID=91

2018-May-25 UT 16:15-17:27 Ill=85% Bullialdus observed by Cook_MC on 1979-6-5

     Bullialdus 1979 Jun 05 UT 22:00-23:00 Observed by Cook M.C. 
     and J.D. (Frimley, UK, 12-inch reflector, Seeing III-IV, good 
     transparency). MC Cook observed internittently over this time 
     period (due to cloud) and found the crater sharper in a blue 
     filter than in a red filter. No obscuration seen apart from a 
     darkish patch on the SW rim and spreading over onto an area 
     surrounding the rim, which she took to be shadow, though the 
     main shadow was along the east rim of the crater. JD. Cook 
     observed an orange colouration seen on eastern and the cleft 
     on the SW rim. Dark area seen on southern floor of crater, 
     south of central peak. ALPO/BAA weight=1.


2018-May-25 UT 16:15-18:04 Ill=85% Gassendi observed by Grego_P on 2011-10-7 *

     Dennis, UK,300m Newtonian, x150, seeing III, intermittent cloud) 
     - whilst producing some sketches of the crater - observer 
     noticed a faint point of light inside the shadow filled 
     interior, two thirds of the way out from where the central 
     peaks should have been, towards the SE rim. Some uncertainty in 
     being sure about this spot and after interuption by cloud it was 
     not seen later that evening. ALPO/BAA weight=1 to refelct 
     uncertainty of observer.


2018-May-25 UT 17:11-19:06 Ill=85% Eimmart observed by Louderback_D on 1981-4-15

     On 1981 Apr 15 at UT06:27-06:40 D. Louderback (South Bend, WA, USA 
     using a 3" refractor x134 and S=4.5-5 and T=5-0) saw a bright spot on 
     the western wall of Eimmart (sketch supplied) have an unusual 
     brightening and shade. Variations occurred over 2-3 minute intervals. 
     Louderback commented that the spot looked like a flare with its apex 
     located at the crater wall and there was some blurring effect on the 
     spot - it decreased in size during the phenomenon. Seeing worsened 
     later. Apparently on the 18th and 19th of April everything was back to 
     normal. Cameron comments that there is no bright spot on the Moon at 
     this location. Lunar Orbiter IV plates 192-3.2 shows evening

     that he could only just see the central craterlet on nights of 
     2-5th Jun and it was of reduced in brightness from normal. 
     North reported that the floor seemed nearly black, but 
     brighter in a green filter (x144 magnification used). All 
     three observers compared the Plato area to other areas for

2018-May-26 UT 16:16-17:52 Ill=92% Plato observed by Moore_P on 1987-1-11

     On 1987 Jan 11 at UT P. Moore (Sussex, UK) found the the floor of Plato 
     was much more drk than the adjacent Mare Imbrium. Furthemore there was 
     a blurring of detail over the northeast wall and onto the nearby floor. 
     detail elsewhere in the crater was OK. By 23:00UT there was less lack 
     of detail effects. M. Cook (Frimley, UK) at 21:55UT noted the obscured 
     area but decided that it was narrower than the same effect one month 
     ago and suspected that she may have been observing towards the end of 
     this TLP. The effect gradually dimmed between 21:55 and 22:45UT. Other 
     craters were normal. G. North was affected by poor seeing conditions. 
     Davies detected a slight obscurtion on the north east corner - it was a 
     misty gray feature at x200. The Cameron 2006 catalog extension ID was 
     292 and the weight was 5. Tha ALPO/BAA weight was 4.


2018-May-26 UT 16:16-16:29 Ill=92% Mersenius_C observed by Ward_G on 2005-11-13

     G. Ward (a lunar observer for 15 years) observed an area just south 
     west of Mersenius C to be blurred and in a greenish cloud. The green 
     colour was more like that of dead grass than one gets from a neon bulb.
     The effect was seen from 04:50-04:57UT, but could have been going on 
     before it was first noted at 04:50-UT. Seeing was 6-7/10 4" Refractor 
     (2 element). refractor had been used hundreds of hours before (over a 
     10 year period) with no similar colour was seen. The observer checked 
     other areas but did not see any similar effects. They also rotated and 
     changed eyepieces, but this made no difference to the TLP. The TLP site 
     seen was picked up on an image taken earlier at 04:47UT by W. Bailley,
     from Sewell, NJ, USA. Unfortunately the area concerned, a mountain on 
     the image, was saturated and so we cannot tell if a colour was present 
     there and the seeing was poor.


2018-May-26 UT 16:16-17:07 Ill=92% Bullialdus observed by Gray_R on 2006-12-2

     At 03:30UT observer noticed a hint of yellow colour
     on the floor of the crater and by 03:57UT the south
     east and central parts of the floor and the circular
     feature on the south west floor had turned a deep
     yellow colour. The rest of the crater remained colourless.
     Other craters also remained colourless. By 04:05UT the colour
     was fading and by 04:15UT it was gone. Maurice Collins
     in New Zealand took some low resolution colour images about
     4 hours later but these failed to show any yellow colour.
     Zac Pujic obtained colour images at a different time of
     natural surface colour on the Moon and finds that Bullialdus
     does actually have a natural yellow cast to most of the floor.
     However this does not explain the variability in colour strength
     seen by Robin Gray. ALPO/BAA weight=3.

     (Montevideo, Uraguay UT 03:15-03:23) showed that Torricelli B 
     was dark, and there was some brightness variability although the 
     background setting on these images was low and seeing could 
     account for the brightness variation? An ALPO report.

     all parts of the floor were sharp although some darkening was visible 
     in the north west and a hint of obscurtion. The east wall though was 
     quite sharp. Mosely could see the central craterlet but from 8-6 
     o'clock tricky to define (Foley says that this effect has been seen at 
     this colongitude before). Streak ray across the floor of Plato seen

2018-May-31 UT 20:27-21:56 Ill=95% Furnerius observed by Kohman_T on 1986-2-26

     On 1986 Feb 26 at 05:00UT a photograph was obtained by T. Kohman of 
     Pittsburgh, PA, USA (3.5" Questar and 0.25 sec exposure) that had two 
     bands above the limb, resembling ejecta plumes. Cameron suspects that 
     these are probably flare from the eyepiece optics. Cameron 2006 
     extension catalog ID=282 and weight=0. ALPO/BAA weight=1.
