     + image intensified CCD camera, transparency moderate to very poor) 
     observed that Aristarchus was fainter than a nearby magnitude 7.3 star 
     (SAO 146315) and may have varied in brightness and size. However the 
     image intensifier output was quite grainy. No obvious signs of impact 
     flashes or cosmic rays seen during a visual inspection of the video

     + image intensified CCD camera, transparency moderate to very poor) 
     observed that a bright spot near Griomaldi appeared to vary in 
     brightness - however a possible explanation was found because the image

     refractor, x36) observed that Aristarchus could barely be seen, but at 
     02:15 UT it brightened by about two times. Note that brightening might

     Om 1990 Mar 01 at UT 00:59-02:20 D. Fryback (Madison, WI, USA, 8" 
     reflector) observed that Lambert was a star-like point, but later saw 
     it brighten up (02:15UT) by two times (note that this brightening might 
     refer to Aristarchus - it is worded in an ambiguous way in Cameron's

2024-Apr-12 UT 23:08-00:57 Ill=22% Proclus_C observed by Kolovos_G on 1985-5-23

     Proclus C region 1985 May 23 UT 17:41 Photographed by Kolovos (observer 
     from Thessoloniki, Greece, observing site near Bafra Serrain, Greece, 
     4"refractor, seeing excellent) "Observer took a series of expousres on 
     a portable scope of the Moon. On one of them a very bright slightly 
     elliptical spot was seen. Spot was very close to the Proclus C crater. 
     Upon analysis it was claimed that the spot of light had rotated the 
     direction of illumination of shadows in adjacent craters - however 
     subsequent analysis casts doubt on this. Papers on this report
     were published in Icarus. Rast and Maley suggested that it was sun 
     glint off a spinning US ex-military weather satellite that just by 
     chance came across the field of view of the Moon a few tens of seconds 
     around the time of the photographed flash. Was this a coincidence or
     not? If it were a satellite sun-glint then the satellite would have to 
     be tumbling incredibly fast in order for the flash to be so sharp in 
     the photograph - so the satellite explanation is not completely 100% 
     confirmed." The Cameron 2006 catalog ID=273 and the weight=5. The 
     ALPO/BAA weight=2.

     In 1949 May 02 at UT 03:30-04:00 Barcroft (Madera, CA, USA, 10" 
     reflector, x96) observed in Aristarchus crater, in Earthshine, a 
     dull glow -- silvery phosphorescence.This was not visible for 30 
     min prior. Cameron comments that this is a confirmation of 
     Wilkins TLP from a few hours earlier? The Cameron 1978 catalog 
     ID=519 and weight=5. The ALPO/BAA weight=2.


2024-Apr-13 UT 00:26-01:59 Ill=22% Aristarchus observed by daSilva on 1971-7-26

     On 1971 Jul 26 at UT 21:40-22:05 daSilva (Paranaiba, Brazil, 13" 
     refractor, x224, seeing=good and transparency=fair) observed two 
     brilliant points in Aristarchus - the right one was the more 
     brilliant of the two. The observer says that this was not a TLP, 
     but is similar to other reports (Apollo 15 watch). The Cameron 
     1978 catalog ID=1300 and weight=1. The ALPO/BAA weight=1.

     4.5" and 8" reflector, seeing=excellent), Albert (CA, 8" reflector, 
     x375) and Emanuel (8" reflector) observed star-like flashes in 
     Aristarchus crater. Cameron says this confirmed and that the date 
     in MBMW is 7/3/65 which is local time = 4th UT also but is in error due 
     to misreading of handwriting. The Cameron 1978 catalog ID=883 and

     On 1985 May 24 at UT 21:01-22:40 P.W. Foley (Kent, UK, 12" reflector) 
     observed that Aristarchus was very bright (varied) and had a strong 
     (transient) red/rose colour and the crater floor was glowing. Detail 
     was visible. Mobberley (Suffolk, UK) also found the floor of the crater 
     to be "glowing". Photographs of Earthshine excellent. The Cameron 2006

     On 1982 Dec 22 at UT 19:20-20:10 J-H Robinson (Teighmouth, Devon, UK, 
     10" reflector, x150, seeing=IV-V) could not distinguish between Messier 
     and Messier A. The tail of these features was very bright - two 
     telescopes were used. Moore (Selsey, UK, 12" reflector, seeing=III) 
     could see Messier A but found Messier itself obscured - just see the 
     west wall and thought that the comet like tail was unusual as it did 
     not appear divided. The Cameron 2006 catalog ID=192 and weight=5. The 
     ALPO/BAA weight=3.


2024-Apr-15 UT 23:59-04:20 Ill=54% Earthshine: sporadic meteors

2024-Apr-16 UT 22:58-23:15 Ill=61% Maginus observed by Lord_CJR on 1975-5-18

     On 1975 May 18 at UT2115-2145 C. Lord (St Annes-on-sea, 
     Lancashire, UK, 76mm f/16 refractor, x170, Wratten 25, and 44a 
     Moon blink filters used, Transparency 4.5/5, no wind, S=F). The 
     west flank of Maginus, and the interior, appeared to be partly 
     obscured. No other features in a similar position along the 
     terminator were obscured. No colour blink was detected with the 
     filters, though a pronounced red/white light blink was noted; the 
     device employed a N.D. x4 filter. By 21:45UT the floor was no 
     longer obscured and only Magninus G was masked in a white haze; 
     however immediately adjacent to the terminator was an ill defined 
     misty patch lying where the outer flank of maginus would have 
     been visible. The rest of the terminator was sharp. The 
     obscuration was only seen to advantage in blue and int. light, 
     and the blue/int blink was only very slight. Findlay and 
     McDonnell observed 21:30-23:00 using a 25cm refractor (Seeing II-
     III) but failed to see anything unsual. NASA catalog weight=3. 
     NASA catalog ID #1407. ALPO/BAA weight=2.

     77mm refractor, x83,x166, seeing II-III, transparency fair). 
     Noted on the inside W eall a faint red rose like glow (with a 
     diameter? about it). The red glow varied in brightness with a 
     period of about 2 minutes. It looked somewhat brighter at x166. 
     The glow was still visible when the observation ended at 22:15
     ALPO/BAA weight=1.


2024-Apr-16 UT 22:58-01:16 Ill=61% Vallis_Alpes observed by Madej_P on 1983-6-18 *

     77mm refractor, x83,x250, seeing II-III, transparency fair). 
     After studying the whole length of this valley, the observer saw 
     a change in "albedo" and a small change in colour of the valley 
     floor near to the Plato end. This colour was not seen in a 
     yellow Wratten 15 filter but was noted in a purple Wratten 35 
     filter, and was strong in a red filter. Also the crater

2024-Apr-17 UT 01:23-02:28 Ill=62% Mons_Pico observed by Turner_S on 1979-9-29

     On 1979 Sep 29 at UT10:00-12:00 S. Turner (Maryborough, Australia) 
     observed a strong beacon like flash in white light that moved back and 
     forth in the east wall of Plato (very bright) and Mons Pico. tried 
     changing eyepiece and the field of view, but this wasn't the cause of 
     the effect. A check at 11:07UT did not show the effect, but it was back 
     again by 11:18UT being more pronounced at Mons Pico than the east wall 
     of Plato. SSW of Mons Pico was also blinking slightly. At 11:32 the 
     blinking effect was irregular 5-10 sec and this continued until 
     12:00UT. Cameron 2006 catalog ID=71 and weight=0 but she suggests 
     atmospheric scintillation as a cause. ALPO/BAA weight=1.

     reflector, x350), Moseley (Armagh, Northern Ireland) and P. 
     Moore (Selsey, UK) observed nothing unusual in Alphonsus at 
     18:40UT, but at 18:45UT Ringsdore saw a blurring. At 18:43UT 
     Mosely saw a reddush-orange patch and this was confirmed by 
     Moore. NNW of the central peak, Mosely got a blink, but Moore 
     did not because of too much stray light. The colour was like
     Jupiter's red spot, but less pronounced. The Cameron 1978

     probably local time) Miranda (Plaui, Brazil, 4" refractor, 
     x80) observed two grooves going from east to west, broadening 
     towards the west, across Archimedes. A drawing was supplied. 
     Apparently this was the first time that this was ever seen.

     On 1982 Aug 01 at 00:00-01:00 K. Marshall (Medellin, Columbia, 12" 
     reflector, seeing I-II) noted shading on the east floor of Plato that 
     was apparently lighter than the rest of the floor and this was seen at 
     both low and high magnifications. Foley notes that this was unusual. 
     There were three craterlets visible on the floor - the central one was 
     the brightest. Cameron 1978 catalog ID=178 and weight=3. ALPO/BAA

2024-Apr-19 UT 23:29-00:40 Ill=86% Mare_Crisium observed by Williams_AS on 1881-5-9

     A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and 
     definition fairly good. Observer noticed that the Mare seemed covered 
     with a close network of innumerable streaks, and spotted with countless 
     numbers of light specks, so that it would hardly be possible to 
     delineate them all in one night. The spots and streaks together must 
     have numbered ~1000. The observer had never seen anything like the 
     number of spots and streaks. Peirce A, was not at all easy to see and 
     neighboring spots almost as bright made it difficult to distinguish 
     which one was Peirce A. ALPO/BAA weight=3.


2024-Apr-20 UT 00:18-02:04 Ill=86% Gassendi observed by Spencer_S on 1976-4-10

     On 1976 Apr 10 at 21:15-21:49UT S.Spencer (60mm refractor x60, seeing 
     quite good) noticed a faint red glow at the south west wall of Gassendi 
     covering a span of about 35 deg arc. The observer had some doubts about 
     this because they were using a small telescope, but thought that they 
     ought to report it, just in case. A BAA Lunar Section report. ALPO/BAA 
     weight=1.


2024-Apr-20 UT 01:53-03:43 Ill=87% Aristarchus observed by Moore_P on 1985-5-30

     On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector) 
     and at the same time Doherty (Sussex, UK, 15" reflector) observed a 
     strangely bright and pink/red north rim of Aristarchus crater during 
     UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT. 
     M.C. Cook (Frimley, UK) found the northern wall to have a red/purple 
     colour but the effect vanished after 50 minutes. Cook also saw a "V"-
     like notch in the NW crater shadow and this appeared to be bigger than 
     normal. G. North (Sussex, UK) saw a tinge of pink colour on the 
     northern rim and a bit later a "ruby red" colour on the north-west wall 
     - again this effect lasted 50 minutes. Moseley verified the colour. 
     Finally M. Hather (Yorkshire, UK) suspected the north wall of 
     Aristarchus to be blue in colour. Cameron suspects that this TLP is not 
     spurious colour because it is in the wrong place. The Cameron 2006 
     catalog ID=276 and the weight=5. The ALPO/BAA weight=4.

     USA, 12.5" reflector, x159 and 3" refractor x90, seeing 5/10, 
     transparency 3/6) found that Aristarchus was brighter through 
     a red filter than through a blue filter on its western wall. 
     He checked Aristarchus in two telecopes and obtained the same 
     result. The Cameron 2006 catalog ID=419 and the weight=4. The 
     ALPO/BAA weight=3.

     On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit 
     around the Moon, obtained images of the Cobra Head region of 
     Aristarchus crater that suggested a ~15x colour ratio increase (0.4 
     microns / 1.0 microns) in comparison with images obtained on 1994 Mar 
     03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting. 
     However it was later suggested that this was due to incorrect 
     radimetric calibration procedures being followed. The ALPO/BAA 
     weight=1.

     "Both were fused together as an oval & had a bluish cast on the E.rim. 
     In W#25 filter it was white. At 0100h albedo decreased from 10+ to 9.5 
     & more detail could be seen. Separation of the 2 craters began to be 
     seen at 0007h, details much brighter, incl. c.p. in Aris. @ 0110h main 
     brightness & blue tint shifted to N. rim. At 0116h the SW rim was 
     brightest & no color. At 0122h ray was brightest & no color. At 0122h 
     ray had decreased in length & more details seen in oval. At 0123h ray 
     was broken & smaller, becoming very small at 0125h & at 0126. The knob 
     was gone & the edges not bright any more. Albedo=9. Sketches. (Seeing 
     variations meas. were 1/2s in length so LTP variations not due to local
