2019-Apr-08 UT 12:54-13:44 Ill=10% Taruntius observed by Osawa on 1968-12-23

     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.

2019-Apr-08 UT 12:54-13:44 Ill=10% 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 

2019-Apr-08 UT 13:04-13:44 Ill=10% 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.

2019-Apr-08 UT 13:23-13:44 Ill=10% 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.

2019-Apr-08 UT 13:42-13:44 Ill=10% Gassendi observed by Kilburn on 1969-1-22

     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 
     catalog ID=1117 and weight=3. The ALPO/BAA weight=2.

2019-Apr-09 UT 12:55-14:15 Ill=17% Mare_Crisium observed by Thomas on 1915-12-11

     North shore of Mare Crisium 1915 Dec 11 UT 06:00? Observed by 
     Thomas (Glenorchy, Tasmania) "star-like pt. on N. shore of

2019-Apr-09 UT 12:55-14:37 Ill=17% 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 

2019-Apr-09 UT 13:20-14:53 Ill=17% 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.

2019-Apr-09 UT 13:44-14:53 Ill=17% 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. 

2019-Apr-09 UT 13:47-14:53 Ill=17% 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 
     N & S rims. Saw a pink tinge on SE rim. (A. Cook) saw spur. Color on 
     most craters as seeing deteriorated. Got a blink on SE region > red 
     than blue". The Cameron 2006 catalog ID=87 and the weight=5. The 
     ALPO/BAA weight=3.

2019-Apr-10 UT 12:57-13:43 Ill=26% 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.

2019-Apr-10 UT 12:57-14:27 Ill=26% 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 

2019-Apr-10 UT 12:57-14:24 Ill=26% 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 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.

2019-Apr-10 UT 12:57-13:03 Ill=26% Aristarchus observed by Davis_H on 1988-11-14

     On 1988 Nov 14 at UT 17:25-18:30 H. Miles (St. Minver, 
     Cornwall, England, UK, 5"refractor? x60 and x120) found 
     Aristarchus to be a white ill-defined circular patch. At 
     17:45UT it was a lot brighter (Cameron comments that this 
     might have something to do with sky darkness). In contrast, 
     Copernicus was just seen as a white patch and the Jura 
     mountains could be seen (not as bright). Aristarchus grew 
     brighter over time and there was a bright point on the west 
     wall (seen at x60 and x120). Īt was fainter at 1854 & < At 
     1830. (Foley) said Earthshine cond. Superb with many regions 
     clearly seen, but Aris. was dull. (Cooks) in hazy condition 
     could not detect Aris." The Cameron 2006 catalog ID=338 and 
     weight=0. The ALPO weight=1.

     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 

2019-Apr-10 UT 13:34-15:26 Ill=26% 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.

2019-Apr-10 UT 14:19-16:00 Ill=26% Fracastorius observed by Robinson_JH on 1980-4-20

     On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teignmouth, 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.

2019-Apr-10 UT 14:45-16:00 Ill=27% 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=2.

     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

2019-Apr-11 UT 12:59-13:44 Ill=36% 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 

2019-Apr-11 UT 13:44-15:31 Ill=36% 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.

2019-Apr-12 UT 13:01-14:31 Ill=47% 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.

2019-Apr-12 UT 13:01-14:22 Ill=47% 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.

2019-Apr-12 UT 13:01-13:52 Ill=47% 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.

2019-Apr-12 UT 13:01-13:52 Ill=47% 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.

2019-Apr-12 UT 13:37-15:30 Ill=47% 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.

2019-Apr-12 UT 13:52-15:48 Ill=48% 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.

2019-Apr-12 UT 14:35-16:32 Ill=48% 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.

2019-Apr-12 UT 16:59-17:58 Ill=49% 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 

2019-Apr-12 UT 17:13-17:58 Ill=49% 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.

2019-Apr-12 UT 17:22-17:58 Ill=49% 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.

     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.

2019-Apr-12 UT 17:45-17:58 Ill=49% 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.

     Plato 1789 Jul 30 UTC 21:00? Observed by Schroter (Lilienthal, Germany) 
     NASA Catalog Event #61, NASA Weight=2 (slightly low) Event described 
     as: "Soon after sunrise saw a kind of fermentation on the floor which 
     clearly resembled a kind of twilight, (due to some kind of aberration 
     unknown to the observer?)" For further details see reference:

2019-Apr-13 UT 13:03-14:59 Ill=59% 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 

2019-Apr-13 UT 13:03-14:14 Ill=59% 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.

2019-Apr-13 UT 13:16-14:39 Ill=59% 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.

2019-Apr-13 UT 13:32-15:25 Ill=59% 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.

2019-Apr-13 UT 13:34-15:32 Ill=59% 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.

2019-Apr-13 UT 14:26-16:20 Ill=59% 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.

2019-Apr-13 UT 14:58-16:55 Ill=59% 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.

2019-Apr-13 UT 15:18-17:05 Ill=59% 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."

2019-Apr-13 UT 18:07-18:46 Ill=61% 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.

2019-Apr-13 UT 18:10-18:46 Ill=61% 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.

     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.

     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

     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

     6" Cassegrain, x150 and x180, Seeing 3, high deck of Cirrus clouds) 
     "Torricelli B hard to make out in the videos taken, but images taken 
     through cloud. A check on the image received by the coordinator shows 
     that Torricelli B is in fact visible, but perhaps not very bright. A 
     later observational sequence of images by Raul Salvo (Montevideo, 
     Uraguay UT 03:15-03:23) showed similarly that Torricelli B was dark, 
     and there was some brightness variability although the 
     background setting on these was low" An ALPO report.

2019-Apr-16 UT 13:08-14:32 Ill=89% 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.

2019-Apr-16 UT 13:21-15:18 Ill=89% 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.

     On 1984 Feb 14 P. Moore (Selsey, UK) thought that there was something 
     odd about Mons Pico in that it looked very bright and gave a good 
     impression of a crater. Cameron 2006 catalog extension ID=241 and

2019-Apr-17 UT 17:08-19:05 Ill=96% Plato observed by Moore_P on 1984-2-14

     On 1984 Feb 14 P. Moore (Selsey, UK) observed that Plato was darker 
     than the nearby mare and no detail could be seen on the floor or the 
     eastern wall - the later was obscured. At 23:40UT some dimming was 
     still present on the north east wall and still no detail on the floor 
     of Plato. Cook noticed that the eastern floor close to the wall was 
     misty and also noted no detail on the floor. Amery though noted that 
     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

2019-Apr-17 UT 17:50-19:47 Ill=96% Aristarchus observed by Louderback_D on 1988-1-2

     On 1988 Jan 02 at 06:41-07:08 UT D. Louderback (South Bend, WA, USA, 
     using a 8" reflector, seeing 4 out of 10) observed that at 06:56 UT 
     Aristarchus floor (point F) brightened rapidly from an intensity of 5.2 
     to 6, however at 07:08 UT the spot returned to normal. He also noticed 
     that the bands on the walls varied every few minutes. A mist like 
     appearance was seen on the floor of Aristarchus. Through a red filter 
     he could see through the haze, but floor detail could not be seen 
     through a blue filter. Cameron 2006 extension catalog ID=316 and

2019-Apr-20 UT 17:53-19:29 Ill=98% Torricelli_B observed by Cook_AC on 1985-12-28

     CCD images taken through Wratten 25 (red+near IR) and 87 
     (near IR only) filters. Between 00:02 and 00:25UT there
     was some slight evidence that a fade may have taken place
     however careful analysis by Cook casts doubt on this.
     Probably it was more related to a degradation in image 
     quality due to seeing than a true TLP. An ALPO/BAA
     weight of 1 has been assigned.
