     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

2021-Apr-19 UT 18:31-18:34 Ill=44% 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.

     spot that had been seen on the 21st and 23rd of the same year with 
     abnormal brightness. The spot was near Picard. Williams comments the 
     spot was "nearly as large but a little fainter than Picard, 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

     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 -

     Wall ridge, but very faint" - however this is worth checking 
     out. ALPO/BAA weight=1.


2021-Apr-20 UT 19:16-19:24 Ill=55% 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.

     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 
     to December, with August 1st most likely, and ancilary data is 
     therefore given for this date. The Cameron 1978 catalog ID=729 and

2021-Apr-22 UT 13:54-14:06 Ill=74% 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=74% 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 15:42-17:26 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.

     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.

     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 
     midnight UT values are used to place a limit on the time of 
     observation. Images by Shaw taken at UT 1754, 18:45 and 23:13
     do not exhibit the effect.

     reflector, x159, S=7/10) observed similar light conditions to 1989 Jul 
     15. At 02:00 he observed pink on the south west wall of Aristarchus 
     crater. At 01:24UT the Aristarchus ray was yellowish, however the 
     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 18:35-20:32 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-23 UT 21:00-21:34 Ill=85% Gassendi observed by Darling_D on 1990-10-1

     On 1990 Oct 1st at 00:44-01:24UT D Darling (Sun Praire, WI, USA) 
     observed that Gassendi still had a blink effect when viewed through 
     blue (Wratten 38A) and red (Wratten 25A) filters. No effect was seen on 
     Aristarchus. Gassendi was brighter in the red filter and this was 
     confirmed by Weier. Sketches were made and brightness measurements 
     taken. Both observers used a 12.5" reflector x159. At 01:00UT the NW

2021-Apr-24 UT 13:55-14:12 Ill=91% 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.

     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

     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

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 
     were as follows: Darling (Sun Praire, WI, USA, 12.5" reflector, x159, 
     S=9/10).  D. Weier (Sun Praire, WI, USA, 12.5" reflector, x159, S=

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.
