2021-Apr-03 UT 01:56-03:28 Ill=65% Cabeus observed by LCROSS on 2009-10-9

     On 2009 Oct 09 UT11:00-11:04 NASA's LCROSS upper centaur stage, 
     followed 4 min later by the observation spacecraft, is due to impact 
     into a the crater Cabeus in the hope of kicking up some dust and 
     possible frozen volatiles. Note that this description is intended for 
     observers on the date of impact and it is doubtful that any new
     science could be achieved by re-observing the same area months
     after the impact. If you are observing on the date of impact, then 
     please observe around 11:00-11:04UT and ignore the predicted times in 
     the headings. However this report is included as techniqcally
     if something is seen it is a TLP, albeit man-made! For those observing 
     on the date in question here are a few observing tips to maximize 
     the science of your observations: (1) If you are imaging, then please 
     try to obtain images before the impact because you can then subtract 
     these from images taken during the impact and hence show up faint 
     changes that you might normally miss. (2) If you have a spare scope and 
     camera,use this to observe through filters such as UBVR or I, or if you
     have narrow band interference filters, try observing in
     say Hydrogen Alpha, Methane, OH, or indeed any volatile that you 
     might expect to see in a comet (the main source of water at the poles).
     (3) Please try checking the area long after the impact, just in
     case other effects might trigger a TLP. (4) Please go to some trouble 
     to ensure accurate timings- these will be essential in order to 
     understand the sequence of events - assuming any are seen. Timings can 
     be obtained using a short wave radio or via a GPS. Note that you should 
     always use UT or UTC. (5) Please send any observations that you make 
     into the upload section of the LCROSS campaign observers web site. If 
     you belong to an astronomical society e.g. BAA or ALPO, then do please 
     send copies of your observations to the Lunar Sections of your society 
     or club. (6) Finally this desription will be updated a day or two after 
     the planned impact.


2021-Apr-03 UT 02:49-03:28 Ill=65% Cabeus observed by Grego_P on 2009-9-9

     On 2009 Sep 09 UT23:31:43 P.Grego (St Dennis, Cornwall, UK, seeing II-
     III) suspected a flash south of Cabeus, just beyond the terminator.
     It was not bright, and lasted a fraction of a second. Thinks it might
     have been illusory as he saw some fainter flashes (cosmic rays?) 
     during that nights observing session. ALPO/BAA weight=1.

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

     (Assis, Sao Paulo Brazil, 25cm f/6 Newtonian) "Green colouration 
     seen on a rim of Tycho, effect remained visible for only 2 
     minutes. Attempts to image it shortly afterwards failed as it 
     had finished by then" An REA-Brasil observational report.

2021-Apr-05 UT 02:46-03:28 Ill=42% Tycho observed by Cook_MC on 2009-9-11

     On 2009 Sep 11/12 UT23:28-00:00 M.C. Cook (Mundesley, UK, 90mm Questar,
     x80 and x190, seeing II and transparency moderate-poor) observed
     pink on the north west rim of Tycho and green-blue on the inner
     SW rim. No sign of colour elsewhere on the Moon except for the
     S-E rim of Plato that was red. The Moon was about 20 deg in altitude
     at the time. The effect had gone by the end of the observing period. 
     A simulation of spurious colour in different directions 
     was generated by the BAA Lunar Section and found to possibly account 
     for these colours, although there should have been some strong colours 
     seen elsewhere in Tycho and none were. The BAA/ALPO weight=2.

2021-Apr-17 UT 16:09-17:46 Ill=25% Aristarchus observed by Mitchell on 1969-11-14

     On 1969 Nov 11/12 at UT23:30-01:00 Mitchell, Celis and Marti (Paso 
     Hondo, Chile, 10" refractor, x96, 4" refractor, x80, 3" refractor, x60, 
     seeing = excellent) observed Aristarchus with a blue centre and 
     irregular form, alternating with normal aspects. Some opacity 
     (independent confirmation?) - Apollo 12 watch. The Cameron 1978 catalog 
     ID=1208 and weight=3. The ALPO/BAA weight=3.


2021-Apr-17 UT 16:46-17:47 Ill=25% Aristarchus observed by Madej_P on 1983-5-17

     On 1983 May 17 at UT20:13-20:40 P. Madej (Huddersfield, UK, x38 and 
     x63) found that Aristarchus was normal in appearance, but at 20:19 a 
     blood red disk was seen as bright as a 6th magnitude star. The colour 
     did not vary but the brightness changed from 4 to 8 over a 1.5-3min 
     period, on the south west wall. Foley (Kent, UK, 12" reflector)observed 
     Aristarchus at 22:10 and noted that it had the same rose-violet colour 
     as had been seen by him a day earlier. The Cameron 2006 catalog ID=220 
     and the weight=0. The ALPO/BAA weight=3.


2021-Apr-17 UT 16:47-17:47 Ill=25% Aristarchus observed by Hobdell on 1981-6-8

     On 1981 Jun 08 at UT01:48-02:45 B. Hobdell (St Petersberg, FL, USA, 10 
     and 4" reflectors) could hardly see Aristarchus crater, however at 
     01:48UT it brightened in blue for about 3 minutes. Then at 02:20UT 
     there was a bright flash, and by 02:25UT the crater was very bright, 
     but by 02:45UT it was no longer visible. Cameron 2006 catalog ID=144 
     and weight=0. The ALPO/BAA weight=1.


2021-Apr-17 UT 17:41-17:47 Ill=25% 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). t 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

     On 25 Jun 1993 at UT 23:30-23:52 Carlos Colesanti (Mairinque, 
     Brazil) obtained two CCD images of Julius Caesar crater and 
     noticed a brilliant fuzzy area on the rim of the crater. This 
     appeared in both images and resembled a fuzzy white blob. Note 
     that this is a REA-Brazil observation. ALPO/BAA weight=1.

     Linne 1867 Aug 06 UT 21:00? Observed by Buckingham (England?) 
     "Crater in darkness, he saw a "rising oval spot". Other obs. 
     saw it as a triang. Bold black spot pointing to earth, slowly 
     diffused white & drift of white on slope of pyramid. (indep.

2021-Apr-18 UT 18:21-18:38 Ill=34% 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 
     interesting.

     1987 Feb 06 UTC 02:35 Observed by Darling (Sun Praire, Wisconsin, USA, 
     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.

2021-Apr-19 UT 15:17-16:00 Ill=43% Mare_Crisium observed by Robinson_JH on 1989-1-14

     Mare Crisium 1989 Jan 14 UTC 19:15 Observed by Hedley-Robinson (Devon, 
     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-
     IV. The Cameron 2006 catalog ID=344 and the weight=5. The ALPO/BAA 
     weight=3.


2021-Apr-19 UT 15:21-17:15 Ill=43% Aristarchus observed by Foley_PW on 1978-5-14

     On 1978 May 14 at UT21:30-22:52 P.W. Foley (Kent, UK, 12" reflector, 
     seeing II and transparency excellent, no spurious colour) observed 
     Aristarchus to be very bright in Earthshine and bluish. The CED 
     brightness measuring device gave a very bright reading of 0.9, the 
     brightest he had ever seen ir before was 0.3. Cameron 2006 catalog ID=

     On 1992 Oct 04 at UT 02:15-03:18 D. Louderback (South Bend, WA, USA, 
     3" refractor, x80) found that Mons Piton was very bright and was equal 
     to Proclus (brightness of 9) in white light and 7.5 in violet, and 9.3 
     in red (Proclus was 9.2 in red). n blue both features = (9?). "points 
     on Piton affected were B, D, and C (S, W & N resp.) D in violet was

2021-Apr-19 UT 18:31-19:07 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.


2021-Apr-19 UT 18:36-19:31 Ill=44% 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.


2021-Apr-19 UT 18:36-19:31 Ill=44% 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.


2021-Apr-19 UT 18:54-19:31 Ill=44% Ross_D observed by Harris on 1964-3-21

     On 1984 Apr 08 UT 19:50 Mobberley (14" reflector, x194, seeing 
     III-IV, Transparency Fair-Poor, Cockfield, UK) found that 
     Torricelli B's shadow was 1/2 the way across the floor, which 
     was normal, but that there was a very dar grey/brown shroud 
     around the carter, out to several radii. 
     The ALPO/BAA weight=1.

     reflector, x80 and x320) using a low power eyepiece, observed that 
     bright craters (but not all of them) "glittered like diamonds". These 
     craters were several on the terminator, Proclus, Censorinus, Manillius, 
     Menelaus and Dionysius. The glitter effect was on the west wall crest 
     -- like stars. Higher power revealed these areas to be bright but not

     NASA Catalog Event #61, NASA Weight=2 (slightly low) Event described 
     as: "Soon after sunrise saw a kind of fermentation on the floor which

2021-Apr-20 UT 19:02-20:00 Ill=55% 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.


2021-Apr-20 UT 19:16-20:26 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.


2021-Apr-20 UT 19:47-20:26 Ill=55% 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 
     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 
     to December, with August 1st most likely, and ancilary data is 
     therefore given for this date. The Cameron 1978 catalog ID=729 and

     refractor. Conditions excellent with the Moon at a high altitude) "2 
     second duration white flash seen on the floor of the crater" - BAA 
     Lunar Section Report.


2021-Apr-22 UT 15:16-16:26 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.

     See TLP report for Bullialdus (eastern side) concerning reddish
     areas. At 21:41 it clouded over but at 21:47-21:48 it 
     cleared briefly and the effect was noted on Bulialdus again.
     Also Darney appeared very visible through the red filter. 
     Probably both effects were spurious colour related as the Moon

     On 1978 May 18 at UT20:45-21:53 J.D. Cook (Frimley, UK, 12" 
     reflector, x240) observed Promitorium Laplace to have 
     visually a brown colour - though no Moon Blink (red and blue

     On 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6" 
     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

     On 1989 Sep 12 at UT00:58-02:25 D. Darling (Sun Praire, WI, USA, 12.5" 
     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 
     2006 catalog ID=375 and the weight=1. The ALPO/BAA weight=1. 


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.

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


2021-Apr-23 UT 23:45-00:18 Ill=85% Aristarchus observed by Kozyrev on 1955-10-28 *

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

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

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=
     9/10), W. Cameron (Sedona, AZ, USA, 8" reflector x110 and x220, T=6 and

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 1983 Jan 29 at UT22:09 M.Mobberley (Sulfolk, UK, 14" reflector) 
     noted that Arago B had a slight tinge of violet colour, and was a lot 
     less (bright?) than Torricelli B's blueness. Other craters checked but 
     were not showing any blue colour. The Cameron 2006 catalog ID=198 and

     On 1983 May 28 at UT 01:50-03:00 K. Marshall (Medellin, Columbia) 
     observed the whole region of Aristarchus, Herodotus and Shroter's 
     Valley all to have a brightness of 3 and all blue and impossible to 
     focus on (he had never seen it like this before). Also the interior of 
     Aristarchus was invisible. Brightness measurement taken and a sketch 
     was made. The Cameron 2006 catalog ID=222 and the weight=3. The 
     ALPO/BAA weight=3.


2021-Apr-28 UT 00:24-01:04 Ill=99% 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.


2021-Apr-28 UT 02:09-02:58 Ill=99% Copernicus observed by Rawlings_G on 1978-4-23

     On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50) 
     observed a bright flash (~0.3 sec duration) near to Copernicus (20W, 
     9N) with rays to the south east whilst he looked through a finder 
     scope. Moore, who studied the drawing, suggests that the area of the 
     flash was near Copernicus. However Cameron says this cannot be the case 
     if the flash was in darkness as mentioned in the BAA Lunar Section 
     circular. She comments that it might have been a meteor? The Cameron

     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 
     effect decreased. Moore detected red the next night as well (May 25th)

     On 1986 Feb 26 at 05:00UT a photograph was obtained by T. Kohman of 
     Pittsburgh, PA, USA (3.5" Questar and 0.25 sec exposure) that had two 
     bands above the limb, resembling ejecta plumes. Cameron suspects that 
     these are probably flare from the eyepiece optics. Cameron 2006 
     extension catalog ID=282 and weight=0. ALPO/BAA weight=1.

     USA, 6" reflector, x200) "Perculiar thread of shadow connecting the 2 
     craters. Sun's elev. @ 6deg. Drawing (possibly a high peak on E.wall of 
     A casting a shadow?)" NASA catalog weight=1 (very low). NASA catalog ID
     #1342.


2021-Apr-30 UT 02:33-03:27 Ill=88% Plato observed by Wilkins_HP on 1944-3-12

     On 1944 Mar 12 at UT 23:00 H.P. Wilkins (Kent, UK, 8.5" reflector) 
     observed that Plato appeared incomplete - the central crater had it's 
     north wall obscured. cameron comments that maybe this was due to the 
     low altitude of the Moon? The Cameron 1978 catalog ID=491 and 
     the weight=4. The ALPO/BAA weight=2.


2021-Apr-30 UT 21:34-23:31 Ill=80% Copernicus observed by De_Groof on 1989-1-26

     On 1989 Jan 26 at UT 03:45 De Groof (Belgium) noted a white few second
