2020-May-01 UT 00:00-00:06 Ill=51% Alphonsus observed by Jasmin_G on 2003-4-10

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


2020-May-01 UT 00:00-00:10 Ill=51% Chacornac observed by Khachatryan_S on 2009-8-28

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


2020-May-01 UT 00:03-00:10 Ill=51% Unknown observed by Fauchier on 1886-5-11

     Fauchier of Marseilles, France, seeing=good - fair and the Moon at a 
     high altitude, saw two lights on the Moon brighter than any others 
     during similar circumstances. They had colour. These had not been seen 
     before and he ruled out cromatic aberation. Cameron 1978 catalog ID=249

2020-May-01 UT 19:14-20:19 Ill=61% Montes_Carpatus observed by McCorkle on 1955-8-27

     On 1955 Aug 27 at UT 01:51 McCorkle (Memphis, Tennessee, USA, 6.5" 
     reflector, x200) observed a 2nd magnitude bright flare on the dark side 
     of the Moon. This remained steady, fading slightly before abruptly 
     disappearing. Cameron suggests that this might have been a meteor. The 
     Cameron 1978 catalog ID=604 and weight=0. The ALPO/BAA weight=1.

2020-May-01 UT 19:20-21:14 Ill=61% Aristarchus observed by Madej_P on 1984-12-31

     Although the crater was on the night side, a small bright spot
     was seen. This was blue, almost UV, and equivalent to a star of
     magnitude 2. It flashed over intervals of about 30 seconds
     and changed in colour from UV to blue. The BAA Lunar Section
     TLP network was alerted. Mobberly and J.Cook did not see much
     although J. Cook may have seen something, but located else where?
     Cameron lists this as a confirmed? observation? The Cameron
     2006 TLP xtension catalog has this TLP with an ID No. of 258
     and a weight of 4. The ALPO/BAA weight is 2.

     UK, using a 150cm f/8 reflector, with seeing I and 
     transparency good, little spurious colour, just a little in 
     Plato). Although observing since 21:25UT the observer noticed  
     a just detectable faint green colour just after the dark shade 
     around the inner eastern crater rim. The effect faded and by 
     22:05UT had completely gone. This report is not in the Cameron 
     2006 catalog. It is a BAA report. The ALPO/BAA weight=2.


2020-May-01 UT 21:08-23:05 Ill=61% Plato observed by Moore_P on 1995-9-3

     On 1995 Sep 03 at UT19:40-20:15 P. Moore (Selsey, UK, 15" reflector at 
     x400) observed that the floor of Plato was much darker than he would 
     normally expect and futhermore no interior craterlets were seen. there 
     was however a white patch that was barely visible at the location of 
     the central craterlet should have been. G. North (UK) attempted to 
     observe nut the Moon was too low and seeing terrible. F. Doherty 
     reported Plato normal. Cameron 2006 catalog ID=475 and weight=3.

2020-May-01 UT 21:17-23:08 Ill=61% Torricelli_B observed by Foley_PW on 1983-2-21

     On 1983 Feb 21 at 20:00UT P.W. Foley (Maidstone, Kent, UK, 12" 
     reflector) noticed a deep steel blue colour inside Toricelli B with a 
     lighter colour about 10-15 miles outside. Foley came to the conclusion 
     that this was too visible for its size. Cameron 2006 Catalog extension 
     ID=206 and weight=3. ALPO/BAA weight=2.


2020-May-01 UT 21:55-23:50 Ill=62% Tycho observed by Albert_J on 2010-8-19

     On 2010 Aug 19 at UT 00:50-01:02 J.Albert (Lakeworth, FL, USA, 
     C11, Transparency 3, Seeing 7-8, 86F and very humid. Oberver 
     checking out repeat illumination condition appearence for Tycho 
     concerning LTP #468 in the 1978 Cameron catalog. Did not see the 
     effect from the original TLP report, but did see, immediately at 
     looking at Tycho a very faint hint of redness in a pencil thin 
     arc (< 1/4 circumference of the rim) confined to the top of the 
     rim of the well-lit north east wall. Coloured arc similar in 
     thickness to Rupes Recta, but not as sharply defined. The outer 
     (E) edge was perhaps sharper than the inner edge. The redness 
     was more on the inside of the top of the rim. The outside of the 
     rim was bright white. This effect was seen in three different 
     eyepieces, at 311x, 224x and 400x. Checked for the effect on 
     other craters nearby but could not see this effect anywhere 
     else. The colour had dissapeared by 01:02UT. The fade took about 
     1-2 minutes. Observation of Tycho continued until 01:06UT, but 
     all seemed normal. Quick checks were made again on Tycho 
     periodically until 02:50UT but the colour was not seen again. 
     ALPO/BAA weight=3.

     On 1980 May 23 at UT21:14-22:18 G. Blair (Bridge of Weir, 
     Scotland, UK, 216mm reflector, seeing II-IV) found a red tinge 
     along the western wall of Coperncius, perhaps 32km in length. 
     This was invisible in a blue-green Wratten 44a filter, but was 
     unmistakble in a red Wratten 25 filter. Could have been 
     spurious colour - but no other regiosn were affected. The

     Brazil) saw in the region of Littrow and an area of dark mare 
     south west from Littrow to Argaeus, abnormal darkness, and a 
     rapid change of form. He also saw a shadow extending south 
     east from Campanus opposite to the Sun - however Foley thinks 
     this is normal. Cameron 2006 catalog ID=96 and weight=0 or 1.

     The UT given in the Cameron 2006 extension catalog are: 20:58, 23:25-
     02:20 and 01:40-04:00, however it is not clear what UT applies to which 
     of the observers or the two features reported as having TLP on that 
     night. On 1984 Feb 12-13 Marshall (South Anerica, seeing=III-II) 
     noticed that Moltke was very bright with a fuzzy violet hue - he had 
     never seen it like this before. Cameron 2006 catalog extension TLP ID=

2020-May-02 UT 19:15-20:20 Ill=72% Plato observed by Marshall_KP on 1984-2-12

     The UT given in the Cameron 2006 extension catalog are: 20:58, 23:25-
     02:20 and 01:40-04:00, however it is not clerr what UT applies to which 
     of the observers or the two features reported as having TLP on that 
     night. On 1984 Feb 12-13 Marshall (South Anerica, seeing=III-II) saw 
     initially no craterlets in Plato, despite the Moon being at a high 
     altitude. At 01:45UT the northwest corner of Plato was red. Again no 
     other craterlets showed. He found the surrounding wall to be too bright 
     and this was confirmed by Crater Extenction Device readings and had 
     problems focussing on the crater. By 02:00-02:50UT he noticed 
     variability in the visibility of the craterlets. By 03:48UT the central 
     craterlet was much brighter than before and the crater doublet had 
     brightened but the southern craterlet was still invisible. Cameron 
     comments that Marshall was a very experienced observer. A. Cook (of 
     Frimley, UK) obtained a photodiode line scan image of Plato. The 
     brightness of the north west wall was brighter than the bright area on 
     the west wall. Marshall and Mosely both saw a dark area on the floor of 
     Plato close to the south wall (from clock position of 11 o'clock. There 
     was a prominent white spot on the floor and the central craterlet was 
     seen, but only under good conditions. Mosely does not discuss the west 
     and north west wall brughtnesses that were seen earlier by Cook and 
     Marshall. Cameron 2006 catalog extension TLP ID=240 and weight=2.

     2-5th Jun and it was of reduced in brightness from normal. 
     North reported that the floor seemed nearly black, but 
     brighter in a green filter (x144 magnification used). All 
     three observers compared the Plato area to other areas for

     On 1982 Apr 04 at UT 23:30-00:25 P. Madej (Huddersfield, UK, 7cm 
     refractor & 16cm reflector) noticed the TLP in his refractor 
     first of all at x25. So stepped up the magnification to x111 and 
     found the crater brightness not what he was expecting. He tried 
     different filters but found no difference in brightness. With 
     the 16cm reflector however some changes in brightness were 
     dected. The crater has a very pale yellow colour and it was 
     slightly darker than Lacus Somniorum. P. Foley tried to confirm

     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

     examined the area. The other three bright spots remained brilliant and

     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

     On 1980 Apr 28, Louderback (South Bend, WA, USA using a 8" reflector 
     and a 2.5" refractor) observed a very bright reg region on top of the 
     south west rim of Aristarchus crater. This was on the same side as the 
     ray system between Aristarchus and Herodotus. Louderback noticed some 
     chromatic aberation - blue where he had seen the red patch before.
     Louderback suspects chromatic aberation was the cause although did not 
     see red in that region ever again. "Patch was between his observation 
     points A and C. Point C was 5 points brighter in the red filter than in 
     the blue." A sketch was made. Cameron suspects that the TLP was real.

     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.

     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

     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

     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.

     Louderback, of South Bend, WA, USA observed a bright area over
     Mons Anguis and Eimmart - it resembled a comet and had a bluish 
     colour and varied in brightness. The colour was confirmed as it 
     was not seen in a red filter but could be seen in blue and white 
     light. Other features were checked but did not show anything 
     similar although a violet glare was suspected in the blue filter. A
     sketch was made. Observer made Eimmart 8 in brightness at 07:30UT.

2020-May-08 UT 02:26-04:02 Ill=99% Aristarchus observed by Porter on 1978-8-19

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

     On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300) 
     noticed a lack of detail in the Cape Agarum area - he would normally 
     have expected to have seen some craterlets. However he would not rate 
     this observation much because the seeing was only III and he does not 
     think that it was an obscuration. However just in case he wanted to 
     record this report in the archives. ALPO/BAA weight=1.


2020-May-09 UT 03:55-04:35 Ill=96% Proclus observed by Savill_AM on 1973-11-11

     improving. At 2104h in 12-in refr. at 260x the lower spot 
     seemed distinctly enlarged & vaporous. Decided it was due to 
     poor seeing. Later the 2 spots were better defined & separated 
     but lower moved away fr. larger one & they seemed more 
     separated than earlier. Obs. ended at 2305h when they decided 
     it was not an LTP. but was 2 craters instead of humps. There 
     were neg. repts. from others at the same time. (there are no

2020-May-09 UT 04:19-04:35 Ill=96% Alhazen_Alpha observed by Daw on 1972-10-23

     Alphazen Alpha 1972 Oct 23 UT 22:10?-22:13? (Stoke-on-Trent, UK, 
     21cm Newtonian, x217, seeing very good). Flickering colours seen 
     on the north field of Alhazen Alpha mountain. Above UTs 
     estimated by the observer, but the duration of the effect was 3 
     minutes. Colouration centred on the hills that run north to 
     south between Mare Anguis and Mare Crisium. The colour 
     alternated from east to west about 2 or 3 times per second. The 
     colour was not apparent to the north or south, or indeed on any 
     other features. Telescope field of view moved, but effect stayed 
     in the same place on the Moon. Moon't terminator scanned for 15 
     minutes afterwards, but the effect did not recur. The colour 
     seen was mostly red, with a band of orange, and a strip of 
     yellow nearest the hills, the proportions being 6:2:1. The bands 
     seemed to arc up steep above the Moon's surface and flatten out 
     over the mare surface either side of the hill features. No 
     filters were used in the observation. Observer suspects some 
     kind of diffraction spectrum to explain the larger dispersion in 
     the red end of the spectrum. ALPO/BAA weight=3.

     On 1991 Dec 09 at UT 22:50 D. Darling (Sun Praire, WI, USA, 3" 
     refractor, x36) witnessed a flash in Grimaldi crater. Cameron comments 
     that others had seen a flash there earlier, and there was a meteor 
     swarm. Fritschel (madison, WI, USA, naked eye observing) detected 3 
     flashes in Grimaldi and also at the western limb of the Moon. D. Weier 
     (Sun Praire, WI, USA, 3" refractor, x36) was also observing. The

     Macrobius 1938 Jun 02 UTC 18:00? Observed by McLeod (England? 5" ? 
     reflector) "Changes in dark areas. (near Proclus where Green saw 
     phenomenom. see #443)" NASA catalog weight=2 (low). NASA catalog ID #
     444.


2020-May-26 UT 19:36-21:23 Ill=16% Aristarchus observed by Livesey_R on 1966-4-24 *

     On 1966 Apr 24 at 21:30UT R.Livsey (Scotland, 6" reflector at x275) 
     observed that Aristarchus was "fluorescent" in Earthshine. It is 
     uncertain whether the description of "fluorescent" should be involve 
     this observation being categorized as a TLP, however just for safety it 
     will be assigned an ALPO/BAA weight=1. This was a BAA Lunar Section 
     report.


2020-May-26 UT 19:36-21:15 Ill=16% Aristarchus observed by Foley_PW on 1983-5-16

     On 1983 May 16 at UT20:35-22:10 P.W. Foley (Kent, UK) noted that 
     Aristarchus was dull in Earthshine (UT21:36-21:40). The floor was a 
     luminous rose/violet colour. The Cameron 2006 catalog ID=219 and the 
     weight=0. The ALPO/BAA weight=1.


2020-May-26 UT 19:36-20:47 Ill=16% Aristarchus observed by Miles_H on 1987-3-4

     On 1987 Mar 04 at UT 19:03-19:47 H. Miles (Cornwall, UK, 5" refractor, 
     x30, S=clear) found at 19:03 that Aristarchus was exceptionally bright 
     (even without blocking out the sunlit side of the Moon), being the most 
     easily seen crater on the Moon, and this was despite the sky not yet 
     being dark. The crater had faded by 19:20UT and at 19:47UT Earthshine 
     was no longer visible. CED brightness measurements were made and were 
     less than usual and the inside of the crater may have had a blue/gray 
     colour (unclear from the Cameron 2006 catalog description). The Cameron 
     2006 catalog ID=299 and the weight=2. The ALPO/BAA weight=2.

     On 1880 Nov 06 at UT 20:00 an unknown observer observed a TLP at an 
     unknown location on the Moon. The Cameron catalog has an entry for this 
     date and time but does not specify the location, the observer or what 
     was seen. The Cameron 1978 catalog ID=218 and the weight=0. The 
     ALPO/BAA weight=1.


2020-May-26 UT 20:50-21:20 Ill=17% W_Limb observed by Moseley_R on 1983-5-16

     W.limb 1983 May 16 UT 22:00-23:00 R.Moseley (Coventry,UK, 6" 
     reflector, x60) observed a faint but extensive brightening of 
     the W.limb, perhaps a little stronger at PA=80-90 deg. No other 
     features seen in Earthshine although Aristarchus suspected.
     ALPO/BAA weight=1.


2020-May-26 UT 21:15-21:20 Ill=17% Aristarchus observed by Taylor_TG on 1837-3-11

     1837Mar11 UT 15:27 (20:48 local time) T.G. Taylor (Madras,
     India) whilst observing a star being occulted, noticed a 
     6th magnitude nebulous spot where Aristarchus should be. Had 
     never seen anything quite as bright as this on previous 
     occasions (except the day before). ALPO/BAA weight=2.

2020-May-27 UT 19:36-20:59 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.


2020-May-27 UT 19:40-20:55 Ill=25% Hubble observed by Madej_P on 1984-11-28

     On 1984 Nov 28 at UT 17:30-18:05 P. Madej (Huddersfield, UK) found that 
     the crater Hubble had a cream white oval patch for short while that was 
     2x brighter than it's surroundsings. The Cameron 2006 catalog ID=254 
     and weight=3. The ALPO/BAA weight=2. 


2020-May-27 UT 20:59-22:09 Ill=25% Aristarchus observed by Foley_PW on 1983-5-17

     On 1983 May 17 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=2.


2020-May-27 UT 21:00-22:09 Ill=25% Daniell observed by Madej_P on 1979-4-2

     Daniell 1979 Apr 02 UT 21:45-22:14 Obseved by Madej (Huddersfield, UK, 
     158mm reflector, f/4.2, x36-110, seeing II-III) "Obscuration seen" BAA 
     Lunar Section Report. Cameron says that this was a bright white cloud 
     that covered three quarters of the crater. A yellow filter was used at 
     21:48, but the cloud was still white, albeit thinner (at x110). By 
     22:14UT the TLP was barely visible and again no colour seen. Buczynski 
     (Lancaster, UK, seeing = poor) saw spurious colour. Later (22:31-
     22:46UT?) Mellor obtained some photos, but these revealed no colour.
     The Cameron 1978 catalog ID=48 and the weight=3. The ALPO/BAA weight=2.


2020-May-27 UT 21:26-22:09 Ill=26% Aristarchus observed by Amery_GW on 1983-1-19

     On 1983 Jan 19 at UT 18:00-19:00 G. Amery (Reading, UK) discovered that 
     Aristarchus could not be seen in Earthshine, this was odd because less 
     prominent features could be seen. Other observers (Moore and Foley) 
     confirmed the very low brightness of the crater. The Cameron 2006 
     catalog ID=197 and the weight=2. The ALPO/BAA weight=2.


2020-May-27 UT 21:26-22:09 Ill=26% Messier observed by Amery_GW on 1983-1-19

     On 1983 Jan 19 at UT 18:00-19:00 G.W. Amery (Reading, UK) found that 
     Messier was difficult to define. The Cameron 2006 catalog ID=197 and 
     the weight=2. The ALPO/BAA weight=1.

     On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP 
     coordinator, Patrick Moore, to report a possible colour anomaly in 
     Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing 
     unusual. However by this time North was reporting that, the colour was 
     fading. Two other BAA members were alerted, but were clouded out. The 
     ALPO/BAA weight=3.

     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

     On 1984 Dec 01 at UT 20:00 a British Astronomical Association Lunar 
     Section member (Southam, Warwickshire, UK) found no detail on the floor 
     of Autolycus, despite there being plenty of detail on the floor of 
     Aristillus crater. According to Foley, there should be some detail at 
     this stage of illumination. Grego reports that the observation was from
