2025-May-01 UT 19:08-19:36 Ill=21% Aristarchus observed by Blair_G on 1980-11-11

     On 1980 Nov 11 at UT17:35-18:32 G. Blair (Weir, Scotland, UK) at 
     17:35UT immediately noted that the Earthsine was extremeley bright. All 
     large detail easily seen on unilluminated disk. 17:38UT a definite pale 
     reddish brown tinge enveloped the Aristarchus area. 17:39 seemed to be 
     getting larger and more intense west (IAU) side. Attempted to contact 
     other observers. 17:40UT Aristarchus still had a bright central peak. 
     17:50UT fading a little from the west (IAU). 18:00UT slight revival in 
     brightness. 18:15UT effect still visible when Aristarchus set behind a 
     high western horizon. The two sketches supplied show the illuminated 
     region around the crater with extension to the west (IAU). P. Foley 
     (Kent) found thatAristarchus was bright enough in Earthshine to be seen 
     with the naked eye. Telescope in operation at 18:00UT and the entire 
     Aristarchus region was bathed in violet/rose colour with what appeared 
     to be a strong ray extending to the west (IAU). Detail could be clearly 
     seen inside Aristarchus crater such as the central zone, west and north 
     wall and rim in relief from point southeat to northwest. CED measure 
     0.8 (white), 0.9 (blue), 0.2 (red). No other reading in Earthshine gave 
     a measure in red. Observation ceased by 18:32UT as the Moon was very 
     low. ALPO/BAA weight=3.

     refractor, x60, x100, x135, seeing=excellent) observed the following at 
     Aristarchus: "Conditions again similar (to #1264). Brighter tonite(8 
     deg) than last nite. but not as bright as on the 6th. Pin pts. of light 
     very accentuated. The radial open hand extended fingers form not so 
     frequently, perhaps because of the larger crescent illum. now.". 
     The Cameron 1978 catalog ID=1266 and weight=3. The ALPO/BAA weight=2.


2025-May-02 UT 19:29-20:24 Ill=31% Hercules observed by Gray on 1885-2-19

     On 1885 Feb 19 at UT 19:00-20:00, Gray of England?, saw a small crater 
     (in it?) that was dull red with vivid contrast. The Cameron 1978 
     catalog ID is 247 and the weight=3. The ALPO/BAA weight=3.


2025-May-02 UT 19:50-22:30 Ill=32% Cyrillus_G observed by Paynter_L on 1983-8-13 *

     Cyrillus G 1983 Aug 13 UT  20:17-20:59 L. Paynter (Radcliffe, 
     UK, 22cm reflector, seeing III or better, transparency good). 
     Cyrillus G was relatively bright and surrounded by a shaded 
     area. On increasing the magnification from x65 to x130 he became 
     aware of a diffused "carise" colouration, in and around the 
     crater. The colouration was similar though to other spurious 
     colour on the Moon, but unlike other areas affected by spurious 
     colour, was more diffuse and spread out and not so concentrated. 
     In view of some uncertainty by the observer, ALPO/BAA weight=1.

     In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of 
     twilight (Cameron says also seen by Gruithuisen, Henry and others at 
     times). Webb gives a low weight to his own observation, saying "for 
     want of better optical means". The Cameron 1978 catalog ID=130 and

     reflector, x230) observed in Theophilus that the "c.p. > reddish brown 
     tint to SW (on peak?)" but suspected that it was probably spurious 
     colour, however no colour was seen later. The ALPO/BAA catalog ID=469 
     and the weight=3. The ALPO/BAA weight=2.

     variations in shape and distinctness, seen in an area east of Atlas 
     crater. A drawing was made. It was noted that no other area had a 
     similar effect. Cameron 1978 catalog ID=909 and weight=3. ALPO/BAA 
     weight=3.

     On 2012 Mar 28 at UT 20:45-20:50 Two unknown Italian 
     observers, reported on an on-line formum that they had 
     independently seen a distinct glow with a comma/drop shape. 
     One of them moved the Moon and the glow moved with the Moon. 
     It is uncertain how experienced the observers where. A chart 
     was provided which shows the lcoation of the glow in the 
     western side of Mare Imbrium. It is just possible that this 
     was Aristarchus in Earthshine, though that is very slightly 
     further west and south than the observers reported. ALPO/BAA 
     weight=1.


2025-May-03 UT 18:43-20:26 Ill=42% Eudoxus observed by Trouvelot on 1881-5-4

     2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw 
     Mons Pico to be incredibly bright. Adee reported naked eye visibility, 
     though this does not show up in later CCD images. Jarwaski saw another 
     nearby Mt very bright as well. This has been assigned an ALPO/BAA 
     weight of 1, though I suspect it is just normal for Pico to get quite 
     bright at sunrise.


2025-May-05 UT 17:09-19:20 Ill=62% Montes_Apenninus observed by Armitage_J on 2008-4-13 *

     Patches of brightness seen in the area between craters Aratus and Joy.
     Seemed to the observer to be perhaps slightly brighter than one would
     expect - the observer thought that their observation only barely
     constitured a TLP but decided to send the report in anyway. This
     has been assigned an ALPO/BAA weight of 1.

     8" reflector and 3" refractor, seeing poor) found that the west wall of 
     Eimmart was unusually bright (8.3) and apparently it was almost as 
     bright as the "WEBS(of Aris?) at its brightest". The crater was 
     apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID=
     228 and the weight=3. The ALPO/BAA weight=2.

2025-May-08 UT 20:41-21:32 Ill=87% 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.

     reflector), Harris, Miller (Torrence, CA, 12" reflector), Bell and 
     Calkins (Ojai, Duarts, CA, USA), Kelsey (West Covins, CA, Riverside, 
     CA, USA) observed scintillations in Aristarchus - Cameron says 
     independent observations?). Members of Astronet took part in this 
     observation. Kelsey saw a brightening but not on the order of seconds 
     as others reported. Cameron suspects an atmospheric effect and also
