2021-Apr-01 UT 04:54-06:50 Ill=83% Aristarchus observed by Bartlett on 1955-10-5

     In 1955 Oct 05 at UT 03:40-03:48 Bartlett (Baltimore, MD, USA, 5" 
     reflector, x180, S=6, T=5) observed in aristarchus an itenseley bright 
     blue-violet glare on EWBS, E, and NE wall. The Cameron 1978 catalog IF=
     620 and weight=4. The ALPO/BAA weight=2.


2021-Apr-01 UT 06:40-08:36 Ill=83% Kepler observed by Petrova on 1966-12-31

     Near Kepler 1966 Dec 31 UT 03:00? Observed by Petrova, Pospergelis 
     (Pulkova Observatory, Russia) "Special glow in this area. Confirmed by 
     photoelectric method (Petrova) & polarimetric (Pospergelis?) almost 
     simultaneously recorded by both" NASA catalog weight=5 (very high). 
     NASA catalog ID #1007.


2021-Apr-02 UT 02:51-02:58 Ill=74% Messier_A observed by Moore_P on 1951-10-20

     Messier A 1951 Oct 20 UT 00:00? Observed by Moore (England) 
     "Brilliant white circular patch in it. has seen it & Messier 
     blurred several times." NASA catalog weight=4 (good). NASA 
     catalog ID #545 Note that the date and time given are probably 
     wrong as the Sun is ~7deg below the local horizon at this time. 
     ALPO/BAA weight=1 to reflect this error.


2021-Apr-02 UT 03:12-05:08 Ill=74% Jansen observed by Grego_P on 2013-8-26

     Jansen 2013 Aug 26 UT 00:30-01:30 P. Grego (Cornwall, UK, 20cm 
     SCT, x200, seeing II, transparency good) observed a dark patch 
     just east of Jansen D. He had not seen this before. There maybe 
     a depression here hinted at in LOLA ndata. ALPO/BAA weight=1.


2021-Apr-02 UT 05:04-06:58 Ill=74% Posidonius_J observed by Holt_D on 2008-10-19

     On 2008 Oct 19 during 05:40-06:30UT D. Holt of Chipping, UK observed an 
     anomalous patch of illumination just to the west of the centre of the 
     Posidonius J crater. It is possible that this is just some high ground 
     on the floor protruding through the shadow filled crater at sunset. 
     Therefore this has been assigned a weight of 1 for now, just in case it 
     is a TLP - until proven otherwise.


2021-Apr-02 UT 09:19-10:18 Ill=72% Plato observed by Foley_PW on 1975-6-28

     Plato 1975 Jun 28/29 UT 23:00-01:20. Foley (Wilmington, UK, 12" 
     reflector, seeing, III, good clarity transparency). At 23:00, 
     00:30, and 01:15 blue was seen on the inner wall:floor southern 
     boundary, and red on the corresponding northern floor:wall 
     boundary. However by 01:20, blue was now on the S-NW floor:wall 
     boundary, and red on the NE-SE floor:wall boundary. Atmospheric 
     spectral dispersion existed in many regions, but did not change 
     like the colours in Plato. Similar appearance craters such as 
     Grimaldi, Schickard, and Riccioli, were checked for a similar 
     change in colour, but no change was noticed in these. ALPO/BAA 
     weight=1.


2021-Apr-03 UT 03:45-04:41 Ill=63% 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.


2021-Apr-03 UT 04:57-06:52 Ill=63% Hansen observed by Androsan on 1973-10-17

     On 1973 Oct 17 at Ut 11:30 Androsan (Edmonton, Canada, 6" reflector, 
     x230) observed a glow 1-2 sec reappearance of Saturn's rings at a place 
     of ring's appearance on the dark limb. The observers attributed it to 
     Saturn and its rings. Cameron speculates that it might be due to gas or 
     dust at the lunar surface. Eye was attacted to the glow which 
     delineated the limb at a position angle of 210 deg at emersion, at 
     Earthshine at Edmonton. The Cameron 1978 catalog ID= and weight=2. The 
     ALPO/BAA weight=1.


2021-Apr-03 UT 09:17-10:18 Ill=62% Aristarchus observed by Brook_C on 2004-12-3

     Aristarchus 2004 Dec 03 UT 00:00-01:00 Observed by Brook (Plymouth, 
     England, 60mm OG x120) "Fluctuation in the brightness in Aristarchus 
     still present but less pronounced than yesterday. Also saw the bright 
     short ray on the opposite side to the main ray in Aristarchus that 
     Amato saw yesterday - but this may be normal?" BAA Lunar Section 
     report.


2021-Apr-03 UT 09:23-10:18 Ill=62% Plato observed by Foley_PW on 1975-6-29

     Plato 1975 Jun 29/30 UT 23:05-00:30. Foley (Wilmington, UK, 12" 
     reflector, seeing, III, good clarity transparency). At 23:05, 
     blue was seen on the inner wall:floor southern boundary, and red 
     on the corresponding northern floor:wall boundary. However by 
     00:30, blue was now on the W floor:wall boundary, and red on the 
     E floor:wall boundary. Atmospheric spectral dispersion existed 
     in many regions, but did not change like the colours in Plato. 
     Similar appearance craters such as Grimaldi, Schickard, and 
     Riccioli, were checked for a similar change in colour, but no 
     change was noticed in these. ALPO/BAA weight=1.


2021-Apr-03 UT 09:24-10:18 Ill=62% Aristarchus observed by Beaumont_S on 1989-11-19

     S. Beaumont of Windemere, England noted that the crater appeared 
     to be divided into two. Cameron 2006 Extension catalog ID=381 
     and weight=3. ALPO/BAA weight=1.


2021-Apr-04 UT 04:43-05:27 Ill=52% Alphonsus observed by Brook_C on 2009-9-11

     On 2009 Sep 11 UT00:15-00:20 and 01:00-01:05 C.Brook (Plymouth, UK, 5" 
     O.G., x100, seeing tremourlous but definition improving over time) 
     noticed that the central peak(s) in Alphonsus were brightening 
     gradually. No effect was seen earlier at UT23:30-23:35. One presumes
     that the effect also occured between these two observing times?
     The observer suspects that this was not a TLP, but is uncertain.
     ALPO/BAA weight=1.


2021-Apr-04 UT 09:45-10:19 Ill=50% Aristarchus observed by Cook_MC on 1987-11-13

     M.C. Cook (Frimley, UK, seeing=III-II) noticed that the crater had a 
     blue/green colour and that this varied, filling a large circular patch, 
     brightly illuminating to the ESE-SSE (IAU?) spilling over the wall and 
     the rim. Shadows inside the crater were large and elongated. The filter 
     response was greater in the blue than through a yellow or red 
     Microfiche. Spurious colour was noticed elsewhere but not in 
     Aristarchus. Cameron 2006 extension catalog ID=313 and weight=3. 
     ALPO/BAA weight=3

     shadow but much brighter than on Aug, 4 (4 deg) & similar to June at 
     same col. The 2nd bright spot seen in June was not seen tonite. 
     (roughness on walls seen in LO IV & V pics show why these pseudo-
     shadows appear)." NASA catalog weight=4 (high). NASA catalog ID #1445.


2021-Apr-05 UT 08:54-10:20 Ill=39% Tycho observed by Darling_D on 1992-8-21

     Tycho 1992 Aug 21 UT 07:58-10:59 Observed by Darling (Wisconsin,

2021-Apr-06 UT 06:44-07:03 Ill=30% Tycho observed by Olivarez_J on 1993-9-10

     During sunset at this feature, with the interior in shadow
     the observer saw that the central peak was nebulous and fuzzy
     and not what one would expect. Cameron saw it on 9 Oct 1993
     at sunset and noted that it was not nebulous, just a grey patch
     although briefly she suspected perhaps two points/peaks?.
     The Cameron 2006 extended catalog ID is 467 and the weight is
     3. The ALPO/BAA weight is also 1. The observer used an 8"
     reflector and conditions were S=4 and T=4.

2021-Apr-16 UT 21:36-21:49 Ill=19% Taruntius observed by Buczynski_DG on 1980-4-19

     On 1980 Apr 19 at UT20:30-22:59. The following is quoted from the 
     Cameron 2006 catalog.... "(Buczynski) alerted by colleague (Greenwood) 
     who used filters W15 (IR), W25 (red), W44A (blue), & W58 (UV) and had 
     located a possible blink in it. (Bucz) used W15, W44A & W25. C.P was 
     very bright in W25 (red), dull but vis. In W44A (blue) & floor was 
     noticibly darker in W44A than in W25. Bright cp vis. In W15 & floor was 
     of a light shade. Other craters checked for color, none found. In 44A 
     floor lost some definition (gas?). Sketches from Bucz. & Greenwood. 
     (Pedler) at 2140, floor area around cp was seen in white & red as 
     normal but blink was vis in white, darker in blue. Checks of other 
     features were negative. (Amery) small dark center & small dark area - 
     not shadow - under S wall. N wall obscured by dark area extending N 
     onto surrounding mare. (normal?) which was difficult to focus (gas?). 
     At 2155 N wall now sharper & dark area less intense. Craterlet Cameron 
     in N wall clearly seen which was invisible 1/2 h earlier. (Saxton) 
     whole crater flashed and blinked at 2155. Could see detail in brighter 
     W 1/2 of crater - not seen earlier. At 2205 seeing poor, at 2215 it was 
     normal. (Blair) at 2155 used red & blue filters & in blue it was darker
     than in red. W. wall not well defined. (J. Cook) saw spurious color on 
     N & S rims. Saw a pink tinge on SE rim. (A. Cook) saw spur. Color on

2021-Apr-17 UT 21:35-22:19 Ill=27% Fracastorius observed by Robinson_JH on 1980-4-20

     On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teignmouth, UK, 10.5" 
     reflector, x180) found, using a Moon Blink device, evidence of colour 
     on the flor patches of Fracastorius crater, brighter in blue than in 
     red. Also the floor to center varied in brightness in blue and in red. 
     Peters observed in white light and found the south east-south wall had 
     a slight orange cast and when a Moon blink was used it was less bright 
     in blue than in red light. M. Cook found spurious colour on the south 
     rim and also on Mons Pico. There was a colour blink reaction on the 
     southeast floor of Fracastorius - this was both faint and blurred and 
     not seen in white light. A.C Cook detected the permanent blink in the 
     south east floor of the crater at 21:47 and a fainter one in the north 
     west (marginally brighter in red than in blue). J.D. Cook found no 
     colour with the Moon blink device. 21:22-22:10 P.W. Foley got a strong 
     colour reaction with the Moon Blink device - brighter in red than in 
     blue and detected a pink colour visually on the south east wall 22:10-
     22:45 (this did not give a blink effect though). Cameron 2006 catalog 
     ID=88 and weight=4. ALPO/BAA weight=2.


2021-Apr-17 UT 21:35-22:45 Ill=27% Petavius observed by Blair_G on 1980-4-20

     On 1980 Apr 20 at UT21:38-21:50, Blair of Renfrewshire, Scotland (used 
     an 8" reflector and seeing=III) saw three patches in Petavius and they 
     could still be seen 7 minutes later. At 21:50UT he used a filter and 
     found the "northern one was brighter in blue, the southern one was 
     brighter in red and the central one was the same shad ein both 
     filters." Cameron comments that the central patch was a permananent 
     one. She then goes onto say that the crater is described as having dark 
     patches that are opposite to what one would expect from Fitton's theory 
     applied to dark features. Cameron 2006 extension catalog ID=88 and 
     weight=4. ALPO/BAA weight=2.

2021-Apr-18 UT 21:34-21:43 Ill=36% Torricelli_B observed by Braga_R on 2001-4-29

     On 2001 Apr 29 at UT 20:50 R. Braga (Italy) reported that without any 
     filter, the brightness of the east wall of Torricelli B was halfway 
     Torricelli C (faintest) and Moltke (brightest). By insering a Wratten 
     25 red filter though, the crater was slightly more evident. However 
     using a blue Wratten 39A filter, the crater vanished completely, whilst 
     Toricelli C remained. The ALPO/BAA weight=3. 


2021-Apr-18 UT 21:53-22:10 Ill=36% Mare_Crisium observed by Webb_TW on 1832-7-4

     Webb (England, using a fluid achromat) saw brilliant minute spots and 
     streaks in Mare Crisium dotting its surface. This was seen near first 
     quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall 
     had all seen it this way at times. Cameron 1978 catalog iD=111 and 
     weight=3. ALPO/BAA weight=2.


2021-Apr-18 UT 22:44-23:58 Ill=37% Aristarchus observed by Butler_FC on 1981-3-12

     On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a 
     10" reflector at 32-64x) noticed that Aristarchus was not 
     visible, although the Earthshine was very obvious. Foley (of 
     Kent, UK, and using  12" reflector) noticed that the crater was 
     only just visible but Plato could definitely be seen. Cameron's 
     2006 TLP extension catalog ID=125 and weight=0. ALPO/BAA 
     weight=2.

2021-Apr-19 UT 21:33-21:37 Ill=46% Alphonsus observed by Lenham_AP on 1952-11-24

     Alphonsus 1952 Nov 24 UT 18:00 A.P. Lenham (Swindon, UK, 3-
     inch efractor x120) noted that the usual dark spots were not 
     visible, but floor ridges and craterlets were surperbly seen. 
     This may not be a TLP but has been given a TLP category as it 
     is a curious appearance and needs to be verified on a repeat 
     repeat illumination apeparance. ALPO/BAA weight=1.

2021-Apr-19 UT 21:33-22:00 Ill=46% Mons_Piton observed by Marshall_KP on 1983-5-20

     On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia) 
     noted that Mons Piton was too bright near the terminator and was 
     surrounded by shadow. A sketch was made. The mountain appeared 
     segmented with one thin shadow line. The mountain looked like a 
     Mexican Sombrero hat. This appearance is normal. What was 
     abnormal was that Piton was brighter than Proclus, and only 
     slightly fainter than Censorinus. The CED brightness 
     measurements were normal Piton=3.6, Proclus=3.5 and Censorinus=
     3.7. Please check to see whether this is still the case. The 
     cameron 2006 catalog ID=221 and the weight=3. The ALPO/BAA 
     weight=1.


2021-Apr-19 UT 21:33-22:05 Ill=46% W_Limb observed by Miles_H on 1987-1-7

     On 1987 Jan 07 at UT19:10-20:30 H.Miles of Cornwall, UK saw two bright 
     patches were seen in Earthshine at clock positions of 4 (this patch was 
     defined by the dark limb and the brightness faded inwards to the disk, 
     over a short distance. "Centred at 60 deg along the limb from the north 
     - a sketch showed approximately 10-15 deg along it") and 5:30 (this 
     second patch was smaller and not so bright as the first patch - it was 
     west of the north pole. P. Foley (Kent, UK) also detcted the patches 
     and said that one was not far from the sunrise terminator. 
     The Cameron 2006 Extension catalog gives this TLP an ID of 291 and a 
     weight of 2. The ALPO/BAA weight=2.

2021-Apr-19 UT 23:02-00:54 Ill=46% Werner observed by Lippert_RM on 1953-9-16

     On 1953 Sep 16 UT03:00 R.M. Lippert (San Diego, CA, USA, 20cm 
     Cassegrain reflector, x90)saw a bright magnitude 1 flash on the 
     Moon, that was probably on the east rim of Werner(?) crater. It 
     is unclear if the observer meant it was really magnitude 1, or 
     was what a magnitude 1 star would have looked like. The flash 
     was yellow-orange in colour. Observation described in the 
     "Observations and Comments" column in the December, 1953 
     Strolling Astronomer (Vol. 7, No. 12), on page 170. The ALPO/BAA 
     weight=3.


2021-Apr-19 UT 23:34-02:11 Ill=47% Aristarchus observed by Mobberley_M on 1985-4-27 *

     Mobberley and Foley note that Aristarchus was very
     prominent in Earhshine. Little other detail seen
     in Earthshine other than the limb. The Cameron
     2006 extension catalog then says: "Confirm moving 
     side to side. Saw bright blue spot in center" however 
     it is unclear whether this refers to Aristarchus,
     or Torricelli-B - the latter was also undergoing a TLP
     at this time. Cameron 2006 extension catalog ID=267
     and weight=5 (confirmed?). 


2021-Apr-19 UT 23:34-02:11 Ill=47% W_Limb observed by Mobberley_M on 1985-4-27 *

     On 1985 Apr 27 UT 22:00 M. Mobberley (Suffolk, UK) could not see much 
     detail in Earthshine (apart from Aristarchus), except that there was a 
     brightness on the western limb of the Moon. The Cameron 2006 catalog 
     ID=267 and the weight=5. The ALPO/BAA weight=1.


2021-Apr-19 UT 23:40-00:57 Ill=47% Pickering observed by Collier on 1971-1-4

     Pickering 1971 Jan 04 UTC 20:29-20:37 Observed by Collier (London, 
     England) "Between Saunder and Rhaeticus, apparently coming from Pick. 
     After 2027h it dimished with extraordinary swiftness, like a light goes 
     out. (experienced observer)" NASA catalog weight=?. NASA catalog ID #

     the IAU renamed some craters.


2021-Apr-19 UT 23:53-00:57 Ill=47% Proclus observed by Darling_D on 1989-12-5

     On 1989 Dec 05 D. Darling of Sun Praire, WI, USA, saw two dark spots on 
     the SE floor of Proclus. The first dark spot was seen through  3" 
     refractor and then also through a 12.5" reflector (35x and 154x). 
     Seeing was S=10 and T=5. He noticed that at 23:00UT the wall spot was 
     less well defined. Darling also comments that he observed reflecting 
     glint, almost as if from a glass surface - he had not seen this effect 
     before. A telephone alert was issued and Caruso verified the spots. 
     Cameron comments that the spots were not shadows because the Sun was at 
     an altitude of 52 deg at Proclus at the time and she states that the 
     steepest slope ever mesured on the Moon was 52 deg and not inside 
     Proclus. Other observers observing were: Weier (6.5" refractor x284 and 
     S=3/10), Caruso (8" reflector x100), and Cameron. The Cameron 2006 
     catalog extesnion ID was 382 and the weight=1. ALPO/BAA weight=3.

2021-Apr-20 UT 00:28-01:14 Ill=47% W_Limb observed by Barrett on 1973-12-2 *

     On 1973 Dec 02 at UT 22:17:33 Barrett and Brick (New York, 3.5" Questar 
     freflector) observed an occultation of Kappa Aquari, a wide double 
     star, on the western limb. The star faded perceptably before 
     disappearing. Cameron says that the fact that the star was a double was 
     not an explanation - she says that there are many reports of similar 
     fades for single stars. The Cameron 1978 catalog ID=1384 and weight=4. 
     The ALPO/BAA weight=1.


2021-Apr-20 UT 00:42-00:57 Ill=47% Curtis observed by Williams_AS on 1882-8-21

     Williams of the UK, on 1882 Aug 21 at 19:30UT (Moon's age 7.9 
     days) noticed a spot at least half as bright, and as large as 
     Picard, near to Picard crater. This observation was reported 
     in the Astronomical Register of the Royal Astronomical Society 
     and is not included in the Cameron catalogs. It is one of many 
     measurements of the brightness of this spot for different 
     illumination angles and is one of three outlying brightness

     peak of massive central mountain group appeared to be in a shadowless 
     having regard to it's claimed height of 6,600 ft. The whole of the

     immediately to the west was a dark (intensity 1.5-2) region extending 
     almost to the foot of the bright inner wall and very diffuse in 
     outline. The observation could not be followed through due to 
     increasing cloud, but on the following night all was normal."

     UK, 78mm APO refractor, x125 & x175, seeing II-III, 
     transparency Good). A brownish (orange) tint was seen on the 
     inner NW wall light terraces - this was immediately obvious 
     when first looking at the crater, but as time progressed the 
     effect became less bright. Other craters were checked for 
     similar coloured tints, but none were seen elsewhere on the 
     Moon. UAI observers in Italy (F. Taggogna & A. Tonon) had been 
     imaging the region in colour 17:57-21:47, but their images do 
     not show any colour on the inner NW rim terraces, the their

     On 1989 Dec 06 at 23:09-23:34UT D. Darling of Sun Praire, WI, USA (3" 
     refractor x36 and x90, and then a 12.5" reflector at x64, S=7/10 and T=
     4, saw dark spots in Proclus (not as dark as those from 5th Dec 1989). 
     Two telescopes were used and the bigger of these revealed some shading 
     on the floor of Proclus approximately a third as intense as he had seen 
     the previous night. A sketch was made. The TLP finished by 22:34UT. 
     Cameron comments that the dark patches could not be due to shadow as 
     the altitude of the Sun was too high at proclus. The Cameron 2006 
     extension catalog ID=383 and the weight=0. The ALPO/BAA weight=2.

2021-Apr-24 UT 03:03-04:54 Ill=87% Vallis_Schroteri observed by Gray_R on 2004-11-24

     Aristarchus Area 2004 Nov 22 UT 04:58-05:49 Observed by Gray 
     (Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5, 
     x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red 
     25. The illuminated west crater wall stood out brilliantly in blue 
     light, much more so than in white light. This was true also of 
     Aristarchus. Red light did not increase contrasts in Herodotus any more 
     than they were in white light. Shadows in Herodotus appeared as black 
     as the night west of the terminator and remained that way throughout 
     the observing period. No TLP seen in Herodotus tonight. A possible TLP 
     was seen to the west of Herodotus near the terminus of Schroters 
     Valley. It was noted at the beginning of the observing period that 
     there were four very bright spots of light, one near the end of 
     Schroters Valley, the other three grouped together a little farther 
     north. Although not far from the terminator they were definitely east 
     of it. It was noted that all of them nearly vanished in the Blue 38A 
     filter while Aristarchus and the rim of Herodotus gleamed brilliantly. 
     At 5:19UT it was noted that the most brilliant of the four lights, the 
     one near the terminus of Schroters Valley, had faded almost to 
     invisibility in white light. When first seen it had been brighter than 
     Aristarchus. It remained very dim after this through the remainder of 
     the observing period, and was unchanged at 7:35-7:49UT when I again 
     examined the area. The other three bright spots remained brilliant and 
     unchanged."

     Coude Rrefractor, x250, Royal Grenwwich Observatory, 
     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.

     to the tip of the cape, north east of the precipitous west
     edge, in the face of the north facing slope. The area
     concerned was diffuse and varied in density despite
     the surroundings not varying. Foley notcied no colour
     elsewhere on the Moon, though Amery thought that he saw
     some in Aristarchus, but Foley thinks this was spurious.

2021-Apr-25 UT 04:39-06:35 Ill=94% Plato observed by Foley_PW on 1978-8-16

     Peter Foley (Kent, UK, 8" reflector, seeing=II) noticed that
     the floor beneath the north wall, and the area over the north
     wall were indistinct (almost out of focus). Despite looking
     elsewhere in the crater and surrounds, no other blurring
     (obscuration of detail) could be seen, indeed everywhere else
     was sharp and detailed. Foley tried several eyepieces but this
     made no difference. He used a crater extinction device but
     found no variations in brightness. There was a slight
     darkening when he used a red filter in the Moon Blink device.
     The obscuration effect weakened between UT20:56 and 21:10,
     was difficult to see at 21:13 and had finished by 00:15.
     Patrick Moore (12" reflector, Dublin, Ireland) saw nothing 
     unusual when he started observing at UT 22:00. Cameron says

     effusion of  smoke effect, which lasted about a minute, seen. 
     It appeared like the fluttering of a bird and passed over the 
     Moon before it evaporated, and must have been foreshortened,

2021-Apr-25 UT 06:03-06:47 Ill=94% Aristarchus observed by Louderback_D on 1985-12-25

     Louderback observed that the south west wall was a creamy deep yellow.
     There was also strong fluorescent blue on the west wall of the Cobra
     Head - Schroter's Valley area and this was similar to the violet glare
     seen on Aristarchus at times. Violet was seen between Aristarchus and
     the Cobra Head. Seeing coditions were poor. Brightening of a point
     near C occurred roughly every 10-15 seconds and lasted 0.5 sec -
     (Cameron concludes that this was not due to the Earth's atmosphere).
     A 0.2 step drop in brightness was seen on point A (twin spots).
     Point C had reduced by 0.6 steps. Elsewhere was stable in brightness.

     Aristarchus normal in red and blue filters however the
     Cobra Head part of Schroter's Valley was brighter in blue.
     Indeed it was very dull in red - Louderback says that this
     was not surprising as the whole areas around Aristarchus is
     brighter in blue. Louderback is an experienced observer

2021-Apr-27 UT 04:13-04:35 Ill=100% Kepler observed by Wildey on 1962-7-17

     Kepler 1962 Jul 17 UTC 06:24,08:36 Observed by Wildey, Pohn (Mt Wilson, 
     CA, USA, 60" reflector+photometer) "Crater was at Vmag 2.68 at earlier 
     obs. which was .47 mag brighter than av. mag. at 15d & it faded to near

2021-Apr-27 UT 05:40-06:39 Ill=100% Aristarchus observed by Darling_D on 1989-10-15

     David Darling observed bright glittering on Aristarchus. This
     was followed by a flare up in brightness at 00:38:05 UT in the
     comet-like ray area of the crater equivalent in intensity to the
     central peak. Then he saw another one on the north east rim of 
     Aristarchus of the same brightness. A third flare was seen at
     00:49UT in south of Herodotus, on the comet-like ray. Another
     two flares were observed at 00:56UT on the north west rim of
     Aristarchus. Darling suspects that these effects were due
     to seeing effects and Cameron agrees. However Weier suspects
     that they were TLP? Brightness measurements by Weier were for
     the south west rim of Herodotus 8.0, for a spot at the Cobra's
     Head 9.0 and 7.5 for C.H. Cameron apparently did not see the flashes
     but did suspect that the interior of Aristarchus was a bit unusual. 
     Don Spain did not see anything unsual at all. Cameron 2006 extended
     catalog ID=380 and the observation weight=3. The ALPO/BAA weight=2.

     On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor, 
     seeing=II) found that the inner bands of Aristarchus were hard to see, 
     this was odd because the seeing conditions were good and he usually 
     sees them? However he did not believe that there was any obscuration 
     going on. The Cameron 2006 catalog ID=37 and weight=0. The ALPO/BAA

     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 
     weight=5. The ALPO/BAA weight=3. 


2021-Apr-27 UT 23:50-23:59 Ill=99% Aristarchus observed by Marshall_KP on 1983-5-28

     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-27 UT 23:50-00:10 Ill=99% Moltke observed by Mobberley_M on 1983-1-29

     On 1983 Jan 29 at UT22:09 M. Mobberley (Suffolk, UK), found that Moltke 
     crater was "exceptionally bright". Other craters (apart from Arago B 
     Torricelli B etc) appeared normal. The Cameron 2006 catalog ID=198 and 
     the weight=5. The ALPO/BAA weight=2.


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 02:09-04:03 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 
     2005 catalog ID=28 and weight=1. The ALPO/BAA weight=1.

     NASA catalog weight=4 (good). NASA catalog ID #625. Note Proclus D does 
     not refer to the crater Proclus D as defined by the IAU, but probably 
     to a spot inside the crater that Bartlett designated D!

     and the colour looked "darker" through a yellow filter and the region 
     was "duller" than normal. The region was 1 intesnsity step brighter on 
     the 2nd measurement, "on all points in it". The comet tail-like ray had 
     3 sections and was "mottled" in appearance. Finally the Cobra Head
