*Indicates a repeat illumination and libration event to within +/- 1 deg for both
A non-* indicates just repeat illumination to within +/-0.5 deg


2024-Aug-01 UT 11:10-11:36 Ill=9% Earthshine: sporadic meteors

2024-Aug-02 UT 12:11-12:16 Ill=4% S_Pole observed by Hill_H on 1985-9-12

     Southern cusp obseved by H.Hill (UK) on 1985 Sep 12 UT0435-0455. 
     Solar Selenographic colongitude=241.3. Observer saw an extremely 
     attenuated cusp extending well beyonf the Moon's prime meridian. 
     There were also dusky ill-defined stips along the Earthlit limb 
     nearby. Note that this is almost certianly not a TLP but is 
     worth checking out if the libration and solar colongitude is 
     similar, just to verify that this is what the Moon normally 
     looks like. ALPO/BAA weight=1.


2024-Aug-14 UT 02:35-05:30 Ill=65% Plato observed by Bartlett on 1964-11-14 *

     Plato 1964 Nov 14 UT 01:00? Observed by Bartlett (Baltimore, 
     MD, USA, 4" refractor?) "Peak on E. wall brilliant white, 
     strong blue band at inner base; on S. wall was a small, bright 
     red spot." NASA catalog weight=4. NASA catalog ID #864. 
     ALPO/BAA weight=3.


2024-Aug-14 UT 03:23-05:30 Ill=65% Mons_La_Hire observed by Klein_HJ on 1887-2-2 *

2024-Aug-15 UT 02:34-05:43 Ill=74% Hevelius observed by Emmett on 1826-4-17 *

     Scarcely a trace of nebulae tonight. As long as to June 10 at
     2000UT? A little blackness remained. (P. Moore thinks it
     was a LTP, WSC it was a permanent feature?) Drawing. Seen
     by Nevelius Emmett, J. Boroughbridge, England. The 2006
     Extension catalog by Cameron assigns an ID No. of 4 and a
     weight of 1. The ALPO/BAA weight=1.


2024-Aug-17 UT 02:30-04:39 Ill=90% Aristarchus observed by Greenacre on 1963-10-30 *

     Aristarchus 1963 Oct 30 UT 01:50-02:15 Observed by Greenacre and 
     Barr (Flagstaff, AZ, USA, 24" Clark Refractor) observed 2 ruby 
     red spots - one just to the SW of the cobra's Head and the other 
     on a highland area east of Vallis Schroteri. A pink colour 
     formed coverting the SW rim of Aristarchus. Effects present with 
     or without Yellow Wratten 15 filer. Similar effects checked for 
     elsewhere on other craters but not seen. So presumed not to have 
     been due to chromatic aberation or astmospheric dispersion. 
     Effecta not seen in 12" refractor, but this may have been a 
     resolution issue. The NASA catalog ID No. is #778. The NASA 
     catalog weight is 5 (highly reliable). ALPO/BAA weight=4.


2024-Aug-17 UT 04:10-07:48 Ill=91% Aristarchus observed by Greenacre on 1963-10-30 *

     Barr (Flagstaff, AZ, USA, 24" Clark Refractor) a violet or 
     purple-blue colour formed beyond the NW of Aristarchus. ALPO/BAA 
     weight=2. This followed an earlier observation that night of two 
     red spots and a pink glow.


2024-Aug-18 UT 05:46-08:01 Ill=96% Mons_Pico observed by Chapman_BW on 1981-10-12 *

2024-Aug-19 UT 03:11-04:38 Ill=99% Aristarchus observed by LeCroy on 1976-2-14 *

     On 1976 Feb 14 at UT23:35-0053 LeCroy (Springfield, VA, USA, 4.5" 
     reflector, x75, S=6 and T=4.5). A blue haze was seen on the east side 
     of Aristarchus and red haze on the west side. At 00:00UT details were 
     more clear and at 00:24UT Aristarchus and Herodotus, were seperated. At 
     00:34UT colours were gone. At 00:35UT blue was on Aristarchus and the 
     area was bright, but was black in a red filter. At 00:53UT the features 
     were clear and the colour gone and the brightness had decreased to 9. 
     Cameron comments that the colour was not due to temp. inversion because 
     of being dark in the red filter, implying a medium). The Cameron 1978 
     catalog TLP ID is 1428 and the weight=1. This is an ALPO report. The 
     ALPO/BAA weight=1.

2024-Aug-19 UT 08:31-09:05 Ill=100% Galvani_B observed by Kilburn_K on 2019-9-13

     Galvani B: On 2019 Sep 13 UT 23:26 K. Kilburn (Manchester, UK, 
     BAA - ED80 refractor, x2 Barlow, Canon 550 DSLR) took a 
     sequence of images from 23:25-23:27 UT. On one of the images, 
     taken at 23:26UT there is a blue/green spot on Galvani B. 
     There is a hint of a possible fade of the spot in the other 
     images but this is not conclussive. Te spot might just be a 
     cosmic ray event or a bright part of the crater rim coming 
     into view under brief exceptional seeing for one frame only. 
     We need simlar illumination, and if possible topocentric 
     libtation images, under different atmospheric conditions to 
     confirm this. It would be great if the images were in colour 
     too. The ALPO/BAA weight=1.

     x260) saw at 01:25UT an unmistakable red-orange glow on the south and 
     south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected 
     it easily. At 01:33UT the colour was barely visible. No TLP alert was 
     issued because the souther edge of Mons Pico also exhibited a hint of 
     colour, and anyway the seeing conditions were poor. Despite this no

     Triensecker Rille 1915 Jul 03 UTC 00:00? Observed by Markov (Russia) 
     "Several spots changed their shapes compared with Gordeenko's depiction 
     on 5/23/12 see #339; which cannot be explained by light variations." 
     NASA catalog weight=3. NASA catalog ID #356.


2024-Aug-25 UT 12:35-12:44 Ill=60% Lichtenberg observed by Barcroft on 1940-10-22

     Lichtenberg area 1940 Oct 22 UT 07:12 Observed by Barcroft 
     (Madera, CA, USA, 6" reflector) "Only slightly redish color this 
     nite, comp. with previous nites (see #'s 467 & 477)" NASA 
     catalog weight=3. NASA catalog ID #478. ALPO/BAA weight=1.


2024-Aug-26 UT 06:54-09:45 Ill=51% Vallis_Schroteri observed by Unknown_Observer on 1994-4-3 *

     On 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a 
     darkening in the Cobra Head, Schroter's valley area of Aristarchus - 
     the best example that he had ever seen. The Cameron 2006 catalog ID=474 
     and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section 
     circular 1995 Oct, p125 and personal communication from David Darling 
     to the BAA on 6/6/1995. Note it is uncertain whether this refers to the 
     Clementine mission or to somebody who observed during the Clementine 
     mission, or somebody with that surname. Anyway if it is the Clementine 
     mission then the date is wrong - possibly the year should have been 
     1994? The Cameron catalogue does actually mention a TIFF on Clementine 
     mission? The Cameron 2006 catalog ID=474 and the weight=3. I am 
     assuming that the year should be 1994 and not 1995? The ALPO/BAA 
     catalog weight=1 until we can find out what the correct date is?

     In 1930 Sep 15 at UT00:00 Vasilev (Russia) observed the following in 
     Alphonsus crater: "During SS there was a triangular spot nr. W. wall 
     until merging with shad. of wall (normal?) (date wrong as age is 3.2d & 
     should be @ 23d. 9/15/30 would be correct: aux. data for 15th". The 
     Cameron 1978 catalog ID=0. The Cameron 1978 catalog ID=398 and

2024-Aug-27 UT 08:52-09:41 Ill=39% Tycho observed by Sandel_J on 1996-2-12

     On 1996 Feb 12 at UT 07:30-08:27 J.Sandel (Caycee, SC, USA) 
     noted a contrast effect inside Tycho at sunset. At 07:30UT there 
     was a slight, but definite illumination of small areas of the 
     crater floor west of the central; peak. Also seen by T. Ferrel 
     (Lawrenceville, GA, USA, SCT C8). This was oval in shape and 
     gray in colour - Ferrel noted some diffuseness. It brightened 
     over 30 minutes. At 08:11UT a definite brightness fade noted in 
     Tycho's central peak. The crater floor had increased 
     illumination of entire crater floor. ALPO/BAA weight=3. 


2024-Aug-27 UT 09:18-11:03 Ill=39% Plato observed by Wilkins_HP on 1944-8-12

     On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52" 
     reflector) observed that central craterlet in Plato was 
     unusually bright and shows up as a bright white spot on his 
     sketch - though this might have been artistic license in his 
     sketch. His written notes refer to the unusual lack of a rim 
     (especially the northern part) to this craterlet. 
     The ALPO/BAA weight=2.
