     On 1972 Dec 10 at UT21:11 Schmitt, whilst orbiting the Moon on Apollo 
     17 saw a flash in Grimaldi. When questioned by Cameron upon return to 
     Earth, he said that he was dark adapted at the time and was unable to 
     say whether it was a cosmic ray or an impact flash. Cameron says that 
     there have been many similar reports in the past from Earth-based 
     observers e.g. TLP report No. 1167). The Cameron 1978 catalog ID=1352 
     and weight=3. The ALPO/BAA weight=2.


2021-Apr-17 UT 09:53-11:09 Ill=23% Aristarchus observed by Moore_P on 1984-1-8

     On 1984 Jan 08 at UT16:30-18:40 P. Moore (Selsey, UK, seeing=III) could 
     not see Aristarchus in Earthsine, despite, Tycho and the mare regions 
     being plainly visible. Foley (Kent, UK) found Aristarchus to be a "soft 
     blue patch" and North (seeing IV-V) found the crater to be one of the 
     brightest features on the Moon. The Cameron 2006 catalog ID=237 and the 
     weight=0. The ALPO/BAA weight=1. 


2021-Apr-17 UT 09:53-10:38 Ill=23% Aristarchus observed by Nottingham_University on 2006-11-25

     CCD images were captured in white light that seemed to show that
     the relative brightness between Aristarchus or Pytheas differed
     considerably to what they were to be one night later on 2008 Nov 26.
     Either Aristarchus was brighter on the 25th or Pytheas was darker.
     Which feature, and which night, the abnormality occurred on is 
     uncertain. One possible explanation might be a brightness
     gradient from glare from the sunlit side affecting the image contrast
     quality of the CCD images for relative photometric measurements.
     This TLP is being assigned a weight of 3 for now.

     reflector, x110 and x220, seeing=good) observed that the west wall of 
     Theophilus crater was red (on terminator). However Posidonius was also 
     on the terminator and no colour was seen elsewhere along the 
     terminator, however Proclus and Piccolomini had pink interiors. At a 
     higher power of x220 a prismatic effect was seen on the terminator in 
     Theophilus and opther craters - "even on W rim of a crater due W of 
     Theoph.". CED measurements of Theophilus... 3.5, 3.9, 3.5. The Cameron 
     2006 catalog ID=407 and the weight=3. The ALPO/BAA weight=1
     because the Moon was below the horizon at this time.

     just over on the night side of the terminator - it was cone shapes and 
     coppery in colour. Cameron comments that maybe it was a very low sun 
     angle effect and she has seen something similar, but on the bright side 
     of the terminator. Jean then goes onto comment that at 10:25UT a very 
     dark line was seen south of the cone i.e. east of the terminator. A 
     sketch was provided and P.Foley commented that the cone did not 
     correspond to any terrain. Cameron 2006 Catalog Extension ID=339 and

     (Winnemucca, NV, USA, 152mm F9 refractor Seeing 6-7, Transparency 6 
     305x) "Blinked Proclus with Wratten Red 25 and Blue 38A filters. 
     Features seen through the red filter were basically seen with the same 
     degree of clarity as in white light, in the case of sunlit walls, maybe 
     a little bit better in the red. With the Blue 38A filter only the 
     brightest part of the crater walls (north end) was visible-the rest of 
     Proclus was dark shadow. At 3:07UT I compared the brightest parts of 
     Proclus with Censorinus and Dionysius. The brightest parts of Proclus 
     and Dionysius were comparable. Censorinus was much less bright than 
     either of the above craters-the halo and crater were much faded over 
     its usual brilliant appearance. Both Censorinus and Censorinus A
     were visible as distinct craters at 114x. The black shadow covering the 
     east 40% of Proclus last night had broken up into three patches 
     separated from each other by lighter bands. These were confined to
     the east crater wall. Only the central patch was black, the other two 
     were considerably lighter. Running along the southwest edge of the 
     crater floor of the crater floor appeared to be a hill to the north
     of which was a less elevated plateau. As the observing period 
     progressed part of the brilliantly illuminated north crater wall 
     developed a darker area which gradually became more prominent. As
     the sun is getting higher I would expect shadows and dark areas to 
     diminish-what was happening here is unknown. However, this is not an 
     unusual event for this part of Proclus". The ALPO/BAA weight=2.

     On 2003 Apr 10 at 00:40UT a GLR observer G. Jasmin (Quebec, Canada, 
     using a 10" F-10 Schmidt Cassegrain) took a photograph of Alphonsus 
     crater on Kodak 400ASA film with an exposure of 1/30th sec. There was a 
     light visible (diameter 10 km) inside Alphonsus and the effect was 
     present for 5 minutes. The observer commented that they have seen a 
     light in this crater many times before, but never as long as 5 minutes.
     This report was submitted to the GLR group in Italy. The ALPO/BAA 
     weight=2.


2021-Apr-20 UT 09:56-10:19 Ill=51% Chacornac observed by Khachatryan_S on 2009-8-28

     On 2009 Aug 28 at UTC 17:00:15-17:00:42 S. Khachatryan (Yerevan, 
     Armenia, 127mm Maksutov-Cassegrain, x171, seeing 9 (1=worst and 10-
     best), Transparency 5-6 on a scale of 1 to 6) observed in the Chacornac 
     area a series of fiery sparks (dot like with tiny rays), slightly 
     elongated with the multitudinal rays orientated towards the south west 
     direction. The colour was mostly red, with some yellow. The final flash 
     was the most clear. The TLP was tiny in area, but "was distinctly 
     bright against any other object on the Moon". The positional 
     uncertainty of the location of the spark effect was approximately +/-
     150 km, based upon an examination of an atlas afterwards. Just prior to 
     the spark effect, something dark, small and fuzzy (only just discrnable 
     to the eye, through the eyepiece) was seen to pass from the west across 
     the Moon in a slight curve, round the surface of the Moon to the east 
     (post observation estimate: seen for 3.5 sec and covered roughly 8% of 
     the lunar diameter in that time). The area of the dark object was 
     comparable in size to (or slightly less than?) craters such as 
     Autolycus F (diameter 3km) or le Monnier E (diameter 4km) i.e. on the 
     limits of vision of the scope used. The location of the flash was not 
     exactly at the same location as the dark object passed across, but gave 
     the impression of starting from it? A back of the envelope calculation 
     of the lunar diameter covered in the time quoted gives an approximate 
     speed (at the lunar distance) of 80km/s or on the very high end of 
     typical meteor streams that pass by. At closer distances, and 
     recalculated velocities, it is unlikely to be a satellite in low Earth 
     orbit (20m/sec at 100km distance), but could perhaps be a bird or 
     insect at a few km range? So was this dark object something in our
     atmosphere by chance passing across the field of view close to the time 
     of the TLP flare or was at the lunar distance and related to the TLP? 
     Incidentally, no attempt was made during this observation to move the 
     scope to check that the TLP remained stationary against the Moon. The 
     ALPO/BAA weight=2.

     very bright. The central peak was also brighter in red than in blue 
     light. However G. North (Herstmonceux, UK, 6" reflector, x135, seeing 
     V-III) and M. Cook (Frimley, UK, 4" reflcrctor, x10, seeing=III)

     it was. Eyepieces change, but the effect remained. Other parts 
     of the Moon checked, but no red seen. There were however 
     splashes of green e.g. Longomontanus on the terminator, 
     elsewhere further inland from the termionator, and little 
     splashes of green on Mare Frigoras - but lasting a brief time. 
     The red colour was as strong as a red LED and the green similar 
     to that of the northern lights. The observer's husband was asked 
     to independetly check Copernicus and remarked that he could see 
     a little bit of green at the top and some red near the bottom, 
     along the line of the internal shadow. Although there were 
     checks for red elsewhere on the Moon and none were seen, the 
     Moon was starting to get low and it is typical of spurious 
     colour in a few respects. Therefore the ALPO/BAA weight=1 for 
     safety.


2021-Apr-21 UT 10:17-11:57 Ill=62% Copernicus observed by Darling_D on 1990-8-30

     On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" 
     refractor, x90, seeing conditions: "at,. boiling") noted a coloured 
     area on the west wall of Copernicus that was unusual in appearance - 
     however other craters along the terminator had a similar effect. There 
     was also a "dazzling bright spot on the E. rim and he witnessed 6 
     flashes from the lighted part of Copernicus over a very short time 
     interval. Cameron comments that the colour may well have been dur to 
     chromatic aberation because a refractor was used. The Cameron 2006 
     catalog ID=408 and the weight=0. The ALPO/BAA weight=1.


2021-Apr-21 UT 10:17-11:57 Ill=62% Proclus observed by Darling_D on 1990-8-30

     On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" 
     reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc. 
     bright interior uniform gray". The Cameron 2006 catalog report is 
     slight unclear as the description for thnis 1990 Aug 30 TLP also 
     includes Copernicus and Censorinus in the list of TLP craters. So one 
     description which might refere to Copernicus, could possibly have been 
     meant for Proclus, namely: "Dazling bright spot on E rim. Rotated 
     eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog 
     ID=408 and weight=0. The ALPO/BAA weight=1.

     On 1960 Aug? 01 at UT 22:00? an unknown observer detected that Vitello 
     was illuminated -it should have been in shadow? Cameron says that if 
     several days before sunrise then the date could have been July through

2021-Apr-22 UT 10:21-14:08 Ill=72% Copernicus observed by Johnstone_GH on 1954-11-6 *

     Observed by G.H. Johnstone of Albuquerque, NM, USA on 1954 Nov 05 UT 
     20:00 (according to Cameron), but 02:00-04:00 according to the
     original observation and at colongitudes 34.7 to 35.7 deg. 4" 
     reflector, x150 used. The obsewrver reported that the western part 
     (about 1/3rd of the interior) was pitch black with shadow. However 
     there was a zone about as wide, or perhaps only a fourth of the total 
     width that was distinctly a lighter bluish shade, almost like twilight. 
     The shadows of the peaks on the western edge of the rim were clearly 
     seen crossing this bluish shadowed area. Then this area ended sharply, 
     and the farside was bathed in light from the rising sun. The shadows of
     the peak were sharply defined across the twilight zone, and the edge of 
     the pitch black shadow was easily defined but not as sharp as the
     darker shadows crossing the the blue twilight zone. The observer 
     checked other craters but did not see this condition in any of them - 
     they all had the abrupt division between black and white that we would
     normally expect to see. Cameron 1978 catalog ID=579 and weight=2.

2021-Apr-22 UT 12:10-14:06 Ill=73% Plato observed by Moore_P on 1981-6-12

     P. Moore at 21:10 found the southern wall (and ontothe southern floor)
     of the crater to be indistinct. Elsewhere in the crater everything was
     sharp. The effect was still seen at 21:42UT, but less strong. A check
     was made for colour with aq Moonblink device, but none was seen. There
     was still a trace of this effect at 21:44UT, although detail was now
     becoming visible. By 21:48UT vertical streaks were seen crossing
     the floor from the obscuration area and these were more visible in the 
     red filter and not in the blue. Cameron comments that undefined patches
     on the floor of Plato are not normal. By 21:55UT some craterlets on the
     floor started to become visible and the TLP for Moore ended by UT22:23.
     P.Foley was alerted by Moore and saw a "amssive dense obsecuration
     on the south wall, south floor and south outer glacis to the Mare".
     Foley noted that by 21:50UT the effect was fading and finished by 
     22:03UT. Foley reported an orange translucent haze covering half of the 
     floor, but floor craterlets could be seen on and off - however his 
     atmospheric seeing conditions were IV. At 22:00 UT Foley reported the 
     floor close to the north wall to be "milky or misty". No detail was 
     visible at 21:15UT and variability in the floor continued until 
     23:10UT. Hedly-Robinson was aleted at 21:35UT and found no difference 
     between red and blue views of the area, however he did find that the 
     south rim was indistinct although this effect had lessened by 22:00 UT 
     and was normal by 22:17UT. M. Mobberly saw a white spot on the floor at 
     21:20 UT, whereas he normally would have expected to see craterlets. 
     Mobberly was alerted at 21:40 UT and took some colour photos. He also 
     made sketches that showed variability in the floor and dark lines and 
     patches in the north west corner. However the altitude of the Moon was 
     low. Cameron mentions that two of the photos show loss of detail at the 
     south wall and beyond.and also a change in the floor markings.The north 
     wall at 21:50UT was strangely reddish (didn't think this was spurious 
     colour). The rest of the wall was sharp at 22:20UT through a yellow 
     filter. Large bright patch in the centre and rest of the floor was 
     apparently of the same shading as Mare Imbrium. The above notes are 
     based upon the Cameron 2006 catalog extension TLP ID 145 and weight=4.

2021-Apr-22 UT 14:33-16:26 Ill=73% Plato observed by Brook_C on 2006-2-8

     C. Brook of Plymouth UK, using a 4" refractor x216, noticed at UT 20:10
     dark patches coming and going (in terms of visibility) on the floor of 
     Plato. Occasional views of the central cratelet (seen as a white spot) 
     were glimpsed. The dark patches seen lasted about 1-2 seconds before
     fading out during each visibility cycle. Teneriff Mountains were 
     checked but no sign of seeing effects that might explain the dark floor
     patches. By 20:26UT the dark patch effect was fading and by 20:31UT 
     floor detail was visible. Observations ceased at UT 20:34. Seeing 
     conditions were II and the Moon was at a high altitude. Other observers 
     were alerted but came on-line after the effect had finished. ALPO/BAA 
     weight=2.


2021-Apr-22 UT 15:42-16:34 Ill=74% Censorinus observed by North_G on 2007-10-21

     At approximately 18:43UT observer noticed that Censorinus, and 
     its bright apron, appeared particularly brighter than normal. 
     There was some spurious colour present - but just a redness 
     along the southernmost extent of the apron visible; could not
     detect any blue along the northern edge however, he did do not
     suspect the colour to be anomalous. A re-examination at 18:51UT 
     revealed that the crater had faded and was seen to fade visibly 
     in real time to normal levels (over about a minute) by 18:53UT. 
     Other features remained constant and so too did the apparent 
     spurious colour.

     reflector, x159) observed an "anomalous black bar across Aris. Nearly 
     digonal to terminator." The nearby crater Prinz had curious shadow 
     patterns, perhaps related to the rising sun projecting shadows from the 
     eastern rim and "reflected down"? "At 0224 W wall had a break in it & a 
     diffuse glow where it should not be. Manske thinks it was Earthshine 
     effect. At 0305 Weier saw Manske's bar - with diffused light and 
     flicker like an aurora - like a gas with electric charge. At 0325 saw a 
     strange glow in Aris. but may be due to atm. though thought it to be a

     Observer noted a bright spot on the interior west wall that seemed
     brighter than what they would have expected. unfortunately the precise
     time of this observation was not recorded so the moon-rise and

     Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon, 
     England) - observer noted that the east outside wall was bright in red 
     and normal in blue. Note that the Moon was 30 deg above the horizon at 
     the time of the observation. The crater returned to normal at 20:58. 
     Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D. 
     Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at 
     times) noticed a possible obscuration over the southern part of 
     Gassendi. He had been observing earlier at 18:40-19:30 but had not 
     detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot 
     outside the east wall is again bright in red., though by 22:25 it had 
     faded  and was gone by 22:28UT. The Cameron 1978 catalog further 
     quotes: "Vivid red spots & general red color seen around rim by 2 obs.

     reflector) took some photos (albeit out of focus) that showed a bright 
     spot on the west rim. Cameron comments that this spot was sharp 
     compared to the rest of the photograph, so was probably a photographic 
     artifact. The effect was not seen in the finder scope. The Cameron 2006 
     catalog ID=103 and weight=2. The ALPO/BAA weight=1.

2021-Apr-24 UT 12:15-14:12 Ill=90% Aristarchus observed by Foley_PW on 1984-1-15

     Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore 
     (Sussex, UK) saw the wall as normal. However Cameron points out that 
     Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely 
     (Covington, UK) at 22:10 UT noticed a brightening on the East wall and 
     at 01:10-01:25 UT suspected that the interior had a weak yellow-green 
     cast to it. Cook (Frimley, UK) states that orange colour was within the
     interior crater, but green beyond the east rim at the 9 O'Clock and
     the south east corner to floor blue/mauvre beyond the northern rim 
     NW/WSW. Foley sstates that orange and blue/mauvre might be spurious 
     colour, but green one cannot get this way. Cameon suggests chromatic 
     aberatons as a possibility but thinks that the observers concerned were 
     experienced enough to recognize this if it were the cause. Cameron 2006 
     catalog extension ID=239 and weight=0. Moore used a 15?" refletor and 
     Foley used a 12" refletor. Mosely experienced II seeing and good 
     transparency. Cook had III seeing and also good transparency. P. 
     Grego made an observation this night too. The 
     ALPO/BAA weight=2.

     On 1980 Jul 24 at UT22:10-22:55 P. Moore (Selsey, UK, 15" reflector, 
     x360 and x400) found an area just south east of the central peak (and 
     upto the wall) to be quite dark in blue light, but normal brightness in 
     red light or in white light. All other features were normal colour-
     wise. At 22:55UT Tycho was normal again. Cameron 2006 catalog ID=103 
     and weight=4. ALPO/BAA weight=3.

     Plato 1870 May 12 UTC 22:00 Observed by Birt (England) 
     "Extraordinary display of lights. Says not effect of sunlight" 
     However an article by Nigel Logshaw in the Feb 2014 LSC suggests 
     that it was probably just normal fine scale spots and streaks on 
     the floor of the crater. NASA catalog weight=4. ALPO/BAA weight=
     1. NASA catalog ID #167.


2021-Apr-24 UT 12:53-13:54 Ill=90% Plato observed by Cook_AC on 1986-12-13

     Plato 1986 Dec 13 UT 20:30 Observed by A. Cook (Frimley, UK, 
     seeing III) North East quadrant of Plato the crater was blurred 
     and ill-defined. Also no craterlets visible anywhere on the 
     floor of Plato until the central craterlet was just glimpsed 
     later at 23:00-23:45, though seeing now III-IV (cirrus at times 
     in the sky). At this later time the NE rim was less blurred than 
     before. ALPO/BAA weight=1.

2021-Apr-24 UT 14:35-16:18 Ill=91% Herodotus observed by Zeller_P on 2016-7-17

     On 2016 Jul 17 UT 03:49 P.Zeller (ALPO, Indianapolis, IN, USA) 
     imaged a pseudo-peak with shadow on the floor of Herodotus, 
     however the image scale and quality of this colour image were 
     not great and the observer suspects that it might be an 
     imaging artefact. ALPO/BAA weight=1.


2021-Apr-24 UT 15:44-17:17 Ill=91% Aristarchus observed by Foley_PW on 1978-5-19

     P. Foley of Kent, UK, using a 12" reflector, seeing=III-II, noticed
     that initially that the crater was pretty dull and that the floor
     was a slate blue-gray in colour at 22:45UT. A noticeable green spot
     inside the crater on the south east appeared at 22:25UT and vanished
     at 00:50UT. Cameron notes that one doesn't get green with spurious 
     colour. Crater Extinction brightness measurements were made at 22:00 UT
     (reading=2.8) and at 23:45UT (reading=3.7). The crater dropped in 
     brightness from 3.7 to 2.8 at 23:50UT and remained lower until 3.0 at 
     23:50-03:15 UT. A graph was produced and showed Proclus and Censorinus 
     at similar brightnesses, but Aristarchus variable. The Earthshine was 
     0.3. Cameron 2006 Extension catalog ID=31 and weight=5.

     Johnson, of Des Moines, Iowa, USA, using a 7" reflector and an 8" 
     refractor, saw a bight streak. The observer looked later, but it was no 
     longer visible. Cameron thinks that it might have been a reflection 
     from the wall. Cameron 1978 catalog ID=423 and weight=1. ALPO/BAA

     lights were seen by Pratt, and 28 by Elger, but only 4 by Gledhill, in 
     Brighton. Atmospheric conditions may have made this difference, or the 
     lights may have run up and down a scale from 4 to 28. As to 
     independence of sunlight, Pratt says (Rept. B.A., 1871-88), at to this 
     display, that only the fixed, charted points so shone, and that other 
     parts of the crater were not illuminated, as they would have been to an 
     incidence common throughout.(30) In Pratt's opinion, and, I think, in 
     the opinion of the other observers, these lights were volcanic."

2021-Apr-26 UT 14:48-16:39 Ill=100% Aristarchus observed by Gibbs_B on 2009-9-3

     On 2009 Sep 03 at UT23:15-23:17 B.Gibbs took some hand held digital
     SLR images of the Moon (Sky conditions clear). Four images were taken 
     at: 23:14:53, 23:15:59, 23:16:05 and 23:17:23 (uncertainty +/-15 sec 
     offset from actual UT). These showed some apparent variation in the 
     brightness of Aristarchus. However there are ways toexplain this 
     through image motion blur when the images were taken. However we 
     cannot be absoultely sure. The ALPO/BAA weight=1.

2021-Apr-27 UT 12:41-13:23 Ill=100% Aristarchus observed by Porter on 1978-8-19

     On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a 
     6" reflector, Seing = 6/10) noticed blue on the north east corner of 
     Aristarchus and an orange glow on the south east wall. They detected no 
     movement or change in brightness. The observer used both eyes, to make 
     sure it was not an eye defect, and three filters: red Wratten 25, blue 
     Wratten 82 and Violet Wratten 47. Porter found that the colours faded 
     for a duration of 5 minutes and then returned. Their right eye gave a 
     good view and using their left eye they suspected that it was 0.5 steps 
     brighter than the remainder of the crater. The suspected colour 
     remained visible, even under moments of good seeing conditions. The 
     colour eventually faded over time and was eventually gone. Porter 
     reportd seein gcolour here on the following night. Apparently other 
     bright spots showed no colour. Fitton suggests that the filters used 
     confirm that the south east wass was definitely red in colour. The 
     Cameron 2006 catalog ID=37 and the weight=0. ALPO/BAA weight=1.

     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.
