2018-Jun-04 UT 10:26-11:42 Ill=72% 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-Jun-04 UT 11:12-11:42 Ill=72% 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.


2018-Jun-05 UT 10:22-11:42 Ill=63% Aristarchus observed by Cowan on 1974-9-8

     blue, misty cloud on th NE rim. Obscur. for 1st hr. then gave way to 
     pink & features became vis. Cloud was tear-drop shape. No movement to 
     glow. Pink cloud glowed too. Very tenuous by 0130h. (Nakamura says

     (Assis, Sao Paulo Brazil, 25cm f/6 Newtonian) "Green colouration 
     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-Jun-06 UT 11:04-11:41 Ill=53% 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.

     3" refractor, x36) witnessed a flash in Grimaldi crater. Cameron 
     comments that others had seen a flash there earlier, and there was a 
     meteor swarm. Fritschel (madison, WI, USA, naked eye observing) 
     detected 3 flashes in Grimaldi and also at the western limb of the 
     Moon. D. Weier (Sun Praire, WI, USA, 3"refractor, x36) was also 
     observing. The Cameron 2006 catalog ID=436 and the weight=5. The

2018-Jun-17 UT 03:36-03:59 Ill=15% 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.

     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-Jun-17 UT 03:42-03:59 Ill=15% 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.

     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 
     N & S rims. Saw a pink tinge on SE rim. (A. Cook) saw spur. Color on

     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-Jun-19 UT 03:19-03:49 Ill=35% Daniell observed by Madej_P on 1979-4-2

     Daniell 1979 Apr 02 UT 21:45-22:14 Obseved by Madej (Huddersfield, UK, 
     158mm reflector, f/4.2, x36-110, seeing II-III) "Obscuration seen" BAA 
     Lunar Section Report. Cameron says that this was a bright white cloud 
     that covered three quarters of the crater. A yellow filter was used at 
     21:48, but the cloud was still white, albeit thinner (at x110). By 
     22:14UT the TLP was barely visible and again no colour seen. Buczynski 
     (Lancaster, UK, seeing = poor) saw spurious colour. Later (22:31-
     22:46UT?) Mellor obtained some photos, but these revealed no colour.
     The Cameron 1978 catalog ID=48 and the weight=3. The ALPO/BAA weight=2.


2018-Jun-19 UT 03:19-04:01 Ill=35% 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.


2018-Jun-19 UT 03:19-04:21 Ill=35% 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-Jun-19 UT 03:19-04:16 Ill=35% Aristarchus observed by Amery_GW on 1983-1-19

     On 1983 Jan 19 at UT 18:00-19:00 G. Amery (Reading, UK) discovered that 
     Aristarchus could not be seen in Earthshine, this was odd because less 
     prominent features could be seen. Other observers (Moore and Foley) 
     confirmed the very low brightness of the crater. The Cameron 2006 
     catalog ID=197 and the weight=2. The ALPO/BAA weight=2.


2018-Jun-19 UT 03:19-03:55 Ill=35% Aristarchus observed by Foley_PW on 1983-5-17

     On 1983 May 17 Foley (Kent, UK, 12" reflector)observed 
     Aristarchus at 22:10 and noted that it had the same rose-violet colour 
     as had been seen by him a day earlier. The Cameron 2006 catalog ID=220 
     and the weight=0. The ALPO/BAA weight=2.


2018-Jun-19 UT 03:19-04:16 Ill=35% Messier observed by Amery_GW on 1983-1-19

     On 1983 Jan 19 at UT 18:00-19:00 G.W. Amery (Reading, UK) found that 
     Messier was difficult to define. The Cameron 2006 catalog ID=197 and 
     the weight=2. The ALPO/BAA weight=1.


2018-Jun-19 UT 03:27-04:41 Ill=36% Copernicus observed by Cook_JD on 1980-4-20

     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-Jun-19 UT 03:49-05:03 Ill=36% 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-Jun-19 UT 04:34-05:16 Ill=36% 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-Jun-19 UT 05:00-05:16 Ill=36% 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-Jun-19 UT 04:04-05:18 Ill=36% Earthshine: sporadic meteors

     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 
     Section observation.Cameron 2006 Catalog Extension ID=339 and weight=3.

2018-Jun-20 UT 03:49-05:11 Ill=47% 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-Jun-20 UT 04:03-04:29 Ill=47% Aristarchus observed by North_G on 2000-2-11

     On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP 
     coordinator, Patrick Moore, to report a possible colour anomaly in 
     Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing 
     unusual. However by this time North was reporting that, the colour was 
     fading. Two other BAA members were alerted, but were clouded out. The 
     ALPO/BAA weight=3. 


2018-Jun-20 UT 05:03-05:46 Ill=47% Mare_Crisium observed by Webb_TW on 1832-7-4

     Webb (England, using a fluid achromat) saw brilliant minute spots and 
     streaks in Mare Crisium dotting its surface. This was seen near first 
     quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall 
     had all seen it this way at times. Cameron 1978 catalog iD=111 and 
     weight=3. ALPO/BAA weight=2.

2018-Jun-21 UT 03:19-04:23 Ill=58% Torricelli_B observed by Mobberley_M on 1984-4-8

     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-Jun-21 UT 03:58-04:49 Ill=58% 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-Jun-21 UT 03:59-05:43 Ill=58% Mons_Piton observed by Marshall_KP on 1983-5-20

     On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia) 
     noted that Mons Piton was too bright near the terminator and was 
     surrounded by shadow. A sketch was made. The mountain appeared 
     segmented with one thin shadow line. The mountain looked like a 
     Mexican Sombrero hat. This appearance is normal. What was 
     abnormal was that Piton was brighter than Proclus, and only 
     slightly fainter than Censorinus. The CED brightness 
     measurements were normal Piton=3.6, Proclus=3.5 and Censorinus=
     3.7. Please check to see whether this is still the case. The 
     cameron 2006 catalog ID=221 and the weight=3. The ALPO/BAA

2018-Jun-22 UT 03:20-04:36 Ill=68% 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-Jun-22 UT 05:25-06:32 Ill=69% 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."

     - 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

     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-Jun-25 UT 05:18-07:55 Ill=92% Deslandres observed by Penzel_E on 1965-5-12 *

     On 1965 May 12 at UT 19:10 E. Penzel (Rodewisch, East Germany) was 
     taking a sequence of images during the impact of the Soviet Lunik 5. He 
     detected a tens of km scale elongated cloud after the impact over a 
     duration of 9.5 minutes. However there are differences between the 
     images elsewhere on the Moon, possibly due to different exposures or 
     some other effects and it is not 100% sure that what he detected was 
     impact debris/cloud?. The ALPO/BAA weight=3.

2018-Jun-26 UT 05:31-06:47 Ill=96% Archimedes observed by North_G on 1988-9-23

     On 1988 Sep 23 at 19:40-19:55 & 20:36-20:41 G. North (760mm 
     Coude Rrefractor, x250, Royal Grenwwich Observatory, 
     Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55 
     image very unsteady. All seems normal in other crtaters with 
     the exception of Arcimedes. Much of the rim seems indistinct 
     apart from a 1/4 length of the west rim. Strongly suspected 
     that this was due to a combination of seeing and illumination. 
     UT 20:02-20:06 - checked the area with a lower magnification 
     10" Astrographic Refractor - the crater seems more normal, so 
     suggesting that the theory was correct. 20:36-20:41 returned 
     to the 30" reflector, and the crater appeared similar to the 
     start of the session. This is almost certainly not a TLP, but 
     it would be helpful to have some images or sketches to check 
     this theory out. Weight=1.

     observed a bright flash (~0.3 sec duration) near to Copernicus (20W, 
     9N) with rays to the south east whilst he looked through a finder 
     scope. Moore, who studied the drawing, suggests that the area of the 
     flash was near Copernicus. However Cameron says this cannot be the case 
     if the flash was in darkness as mentioned in the BAA Lunar Section
