     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

     light shone out on the moon -- a bright point of light in the lunar 
     crater Aristarchus, which was in the dark at the time. It was seen, 
     upon the 4th and the 7th of February, by Capt. Kater (An. Reg., 1821-
     689); and upon the 5th by Dr. Olbers (Mems. R.A.S., 1-159).(25) It was 
     a light like a star, and was seen again, May 4th and 6th, by the Rev. 
     M. Ward and by Francis Bailey (Mems. R.A.S., 1-159).(26) At Cape Town, 
     nights of Nov. 28th and 29th, 1821, again a star-like light was seen

     On 1988 Nov 15 at 10:07-10:40 UT P. Jean (Outremont, Quebec, Canada, 
     4" refractor?) saw to the SE of Eudocus (18E, ~43N) a luminescent area 
     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.

     UK, 5" Coude, Antoniadi II seeing, x150) "Floor blinks indicating 
     colour - used a Moon blink device". 2 areas of the floor were affected, 
     The first one was on the far west of Mare Crisium, next to Proclus 
     crater. The second area was in the NNW, but outside the edge of the 
     mare. Other features elsewhere checked but gave no colour reaction. 
     Peters (UK) though did detect colour elsewhere, but his seeing was III-

     12.5" Newtonian x342) "I was using a 12.5 f5 Newtonian reflector with a 
     9mm eyepiece and 2x Barlow with no filters. I had been observing other 
     features on the Moon when I had panned to the area where the sunrise 
     was taking place on Mount Piton. The mountain peak looked like a 
     shimmering block of ice with a phosphorescence luminescence cloud 
     around the peak. What was really interesting was the shaft of light 
     streaming across the Lunar Maria that appeared like a cone and it came 
     to a point near Mount Piton. The Mountain had the appearance of mother 
     of pearl and the luster or glow that surround the peak only lasted 
     about 20 minutes." The Cameron 2006 catalog ID=296 and gthe weight=4.

     Mons la Hire 1972 Nov 15 UT 09:45-10:18 M.Geisel (Brisbane, 
     Australia, 12.5" f/8 reflector, x90) discovered the TLP, P. 
     Anderson (9.5" reflector) independently confirmed that the TLP
     had an effect in his Moon Blink device - but the effect 
     (suspected that the blink was caused by the extreme nrightness 
     of the mountain?) was weak and thought it not worth further

     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 11:05-11:57 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.


2021-Apr-21 UT 11:05-11:56 Ill=62% Copernicus observed by Horner_E on 2012-9-24

     2012 Sep 24 UT 22:00-23:00 Copernicus. E. Horner (Salisbury, 
     UK, 15cm reflector) observed a prominent red arc where the 
     sunlit part of the interior wall met the shadow. Sometimes the 
     arc was 1/4 the way around the interior, and sometimes half of 
     the way around. Telescope moved, but the red arc stayed where 
     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.

     was illuminated -it should have been in shadow? Cameron says that if 
     several days before sunrise then the date could have been July through 
     to December, with August 1st most likely, and ancilary data is 
     therefore given for this date. The Cameron 1978 catalog ID=729 and

     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 15:42-17:25 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

     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

     entire Moon had a grey-yellow tinge of colour. Chromatic aberation was 
     observed at 01:56UT. By comparison Gassendi was checked and had no 
     colour. At 02:10 the crater wall of Aristarchus was unusual and was 
     quite different in appearance to rims of other craters. The cameron

2021-Apr-23 UT 18:35-18:53 Ill=84% 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.

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

     imaged a pseudo-peak with shadow on the floor of Herodotus, 
     however the image scale and quality of this colour image were

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

     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 18:29-19:39 Ill=100% Aristarchus observed by Mobberley_M on 1984-12-7

     On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK, 
     seeing=IV-V, transparency=good, spurious colour seen) found 2 
     bright pathces on the east rim on alternate sides of a bright region. 
     The band from the central 16km wide region was dark on the east side. 
     Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be 
     not as bright as normal, apart from the band that Mobberley found (1 
     hour later). The dark regions were a murky green colour (bright through 
     green, blue and yellow filters and dark through red and orange 
     filters). Cook (Frimley, UK, transparency=excellent, CCD camera used) 
     found a bright "bulge"on the eastern side. Apparently data suggests 
     that the band was brighter in red than in near IR light. Cook's 
     calibrated brightness measurements suggest that there was no change in 
     brightness over the crater with time. Two other bright points were 
     seen: one at the Cobra's Head and another half way between the east rim 
     of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87 
     (near IR) and combined Wratten 29 and Wratten 87 were used. In the red 
     Wratten 29 filter the brightness falls at22:20 at Shroters valley and 
     then rises in the bright ray. They return to normal at 22:30UT. There 
     was however a lot of measurement noise from the brightness readings of 
     points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The 
     ALPO/BAA weight=3. 


2021-Apr-26 UT 18:43-20:18 Ill=100% Aristarchus observed by Darling_D on 1990-12-2

     F. Graham took some photos of the Cobras Head and found a blue cloud 
     about 50 km in diameter and scattering light - Cameron says that 
     this indicates high density. Darling found the Cobra's Head obscure and 
     variable "clear and bright to diffused". Cameron was alerted observed 
     (02:40UT) variations with periods of approximately 30 seconds, and 
     thought that she could see a red tinge on the east rim of Aristarchus - 
     checks elsewhere found no other colours. Darling found that a blue 
     filter enhanced the effect and a red filter made it disappear. There 
     was a blink at 02:55UT but no blink in the Cobra's Head, which looked 
     fuzzy and lacking in detail. The effect was confirmed by Weier, who 
     also saw two dark spots in the Cobra Head in blue but not in red light. 
     The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall 
     7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south 
     wall 7.0, East wall 8.0, and the central peak 10.0. Observer details

     reflector x200, Moon at gigh altitude above horizon). "Attracted to 
     crater because of an orange hue extending towards Herod. Has seen this

2021-Apr-27 UT 12:55-13:23 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

     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

2021-Apr-27 UT 20:08-20:52 Ill=99% Torricelli_B observed by Mobberley_M on 1985-12-27

     Mobberley noticed that Torricelli B was bright and had an even brighter 
     spot on the inner north wall. The observation was made from UT19:45-
     21:40 using visual and video techniques. There was also a bright region 
     NNE of Toricelli B, that was noticed. Foley examined the video and 
     found that the crater faded in brightness over time and also the bright 
     area to the NNE was not as bright on video as had been seen visually. 
     Foley speculates that because the CCD camera was sesnitive to the near 
     IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and 
     also saw the bright spot on the inner north wall - but saw a blue halo 
     around the crater. Response in blue filter, darkening over whole 
     region. Brightness measures with a crater extinction device (CED) 
     indicated that the crater was 80-85% the brightness of Censorinus. 
     There was a bright area NNE of the region. M. Cook observed 22:10-
     22:16UT (15cm reflector and seeing III-IV) and also saw that the crater 
     was very bright indeed with a spot NNE of the region (same position as 
     28/28 1985 observation) - suspected that the crater might have been 
     brighter than Censorinus, but judgement effected by seeing. In a blue 
     filter the crater dulled leaving the bright spot prominent (but only 
     during a good moment of seeing) - therefore had some suspicion of 
     seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the 
     area, but the seeing was even worse - but did manage a check of the 
     brightness of Torricelli B to Censorinus and now made it one quarter of 
     that of Censorinus and no sign of the crater dimming in the blue as had 
     been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at 
     21:15UT (Dec 27) thought that Torricelli B looked normal and saw no 
     colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images 
     through red+IR (Wratten 25) and IR (Wratten 87) but found no colour 
     differences, though there was a very slight hint that a brightness fade 
     may have occurred between those two observing times. Note that this
     report does not have an entry in the Cameron 2006 Extension Catalog.

     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 
     filters. A sketch was supplied. Cameron notes the coincidence of

     on the south east wall and southern "horn" of the crater. He could not 
     detect colour elsewhere, but felt that the effect might have been 
     spurious colour. With the increasing altitude of the Moon the light

     Filters Blue 38A and Red 29. Macrobius became almost invisible through 
     the Blue 38A and essentially the same as in white light through the Red 
     29. The interior of the crater was completely in shadow. The only part 
     of the east wall that was visible was an apparent high point still in
     the sun and seen as a bright point of light. This faded into darkness 
     before 13:56UT. No sign of any illumination of the east wall crater 
     interior or the interior of the west wall was seen during the
     observation period. The outer west wall was a rough looking, 
     complicated mix of deep shadow and illuminated sunlit terrain." The 
     observer concluded that there was not a TLP - although he did get a 
     filter reaction, this may have been due to the different densities of 
     the filters? ALPO/BAA weight=2.
