     On 1979 Sep 16 at UT 08:00-09:00 D. Darling (Sun Praire, WI, USA, 
     12.5" reflector, x62-x97, clear, but Moon at low altitude) detected 
     four new features that he had not seen before in Earthsine in 
     comparison with what he saw on 16 Jul 1979, this time in the southern 
     part of the Moon. pin-point flashes were seen within these bluish 
     areas. Each time a flash occurred the gas clouds brightened (sometimes 
     by 6x) for a few seconds. Cameron thinks that these are related to 
     moving clouds on the Earth's limb e.g. mackeral sky. Cameron 2006 
     catalog ID=69 and weight=1. ALPO/BAA weight=1.

     reflector) took an Earthshine photograph that revealed Copernicus to be 
     brighter than Aristarchus and Kepler. Cameron comments that usually 
     Aristarchus is the brighter and thought it a bit odd because Copernicus 
     should have been less visible, being nearer the terminator3 The Cameron 
     2006 catalog ID=359a and the weight=5. The ALPO/BAA weight=2.

     angular diameter, 4-5x brighter than the surroundings in Earthshine. 
     The observer did not think that it was a TLP, but Cameron considers the 
     report is similar to many other TLP descriptions of Aristarchus in 
     Earthshine. Marks (England, UK) who was observing at 20:20UT did not 
     note anything unusual in Aristarchus. The Cameron 1978 catalog ID=1121

2024-May-14 UT 04:52-05:49 Ill=37% Daniell observed by Price_M on 1979-12-24

     M. Price of Camberley, UK noticed that an area in relation
     to the central area of the floor could not be resolved. Averted
     vision was used, but this did not help to resolve detail. The crater
     was close to the terminator and was in general sharply in focus
     apart from the suspect area. No spurious colour seen. Sketch
     supplied.P. Foley wonders if the effect was due to the resolution
     limit of Price's scope? Cameron 2006 extension catalog ID=78

     and SAO093052 mag=7.5 that happened to lie in the field of view at the 
     time) in Earthshine. The observer speculates whether this was a lunar 
     meteorite impact or a reflection from an artificial satellite (or 
     indeed as Cameron suggests from an Earth meteor?). The cameron 1978 
     catalog ID=1388 and weight=0. The ALPO/BAA weight=1.

     Torricelli B 2002 Oct 14 UT 02:58-03:43 Observed by Gray (Winnemucca, 
     NV, USA, 152mm refractor x114, x305, seeing Antoniadi III, transparency 
     good) "I was out this morning (2:58-3:43 UT, October 14, 2002) 
     observing Torricelli B. At 3:17 UT the west sunlit wall of the crater 
     brightened from an intensity (Elger Scale) of 5.0 to 9.0. In actual 
     terms it went from slightly less bright than the walls of Picard to as 
     bright as the sunlit west wall of Dionysius. This was observed at 114x 
     in white light, where all three craters were in the field of view 
     simultaneously. This event lasted less than a minute and no comparable
     brightening in Dionysius or Picard was seen. The wall of Torricelli B 
     returned to 5.0 in brightness. I continued to observe Torricelli B in 
     white light until 3:43 UT, but the brightness remained at 5.0. Before 
     the brightening I tried blinking Torricelli with the following 
     combinations of filters: Wratten Red 25 and Blue 38A, Red 25 and Blue 
     80, and Red 25 and Schott BG38 (Blue Green). Nothing showed up more 
     prominently in any combination except the Red 25-Blue 38A combination, 
     where Torricelli B became invisible in the Blue, probably because of 
     the filter density. Both the Blue 80 and Schott BG 38 seemed closer in
     density to the Red 25 than the Blue 38A is. I could not see any details 
     inside Torricelli B during this session, including the bright spot on 
     the NE rim." The ALPO/BAA weight=3.

     "kind of glimmering mist lifted and wafted inside the shady 
     hollow of the crater". Almost certainly this is a combination 
     of atmopsheric seeing on the narrow shadow spires, but we 
     would like observers to look at this visually or obtain time 
     sequence images to try to replicate this effect. This report 
     is assigned an ALPO/BAA weight of 1 for now.

2024-May-16 UT 03:12-05:05 Ill=56% Alphonsus observed by Poppendiek on 1958-11-19

     Large plume-like diffuse cloud over central peak, very
     large compared to central peak (@ approx 30km diameter)
     with intensity much different from other parts. Brightness
     between walls and shadowed floor. Would take 3 minutes to
     collapse, so continuously fed. 13-14 days later, at SS,
     central peak was normal. Kuiper took photos after Kozyrev's
     observations, but saw nothing abnormal. Drawing. Haas saw
     nothing in 12inch reflector at the time. Cameron 1978

2024-May-16 UT 05:39-06:46 Ill=57% Proclus observed by Foley_PW on 1988-7-22

     On 1988 Jul 22 at UT 02:15-04:00 P.W. Foley (Kent, UK, 11" 
     reflector) made a sketch of a dark area of the (East) floor of 
     Proclus that revealed a large anomalous dark region - there 
     should be no shade here when the sun is at an altitude of above 
     50 deg!. BAA lunar section archives reveal similar dark shadings 
     - however on this night it was a different shaped dark area. The 
     appearance was confirmed by several observers. Foley reported 
     that the region affected stretched from Proclus to Theophilus. 
     The TLP was seen in the USA too by D, Darling as early as 
     01:31UT and by others on his TLP network - brightness 
     measurements of the "c.p." were 3.5 and the remainder of the 
     floor was 5.5. However the observers did not all agree on the 
     same position for this dark area. The Cameron 2006 catalog ID=

     On 1989 Jun 12 at UT 21:18-22:25 G. North (Herstmonceaux, UK, 
     Coude, seeing=V) noted at 21:18UT that Torricelli B was 
     "barely visible"- possibly this was seeing related. M. Cook 
     (Frimley, UK, 8" reflector, seeing=IV) found Toricelli B to be 
     Űxtremely dull - impossible to judge shadows on floor in 
     contrast to Cens." Holmes (Rockdale, England, UK, 8" 
     reflector, seeing=II-III) at UT21:30 also found Toricelli B 
     difficult to find at magnifications less than 200x. Cameron

2024-May-18 UT 02:09-02:31 Ill=74% Plato observed by Cook_MC on 2009-4-4

     On 2009 Apr 04 at UT 21:40 M.C Cook (Mundesley, UK) after receiving a 
     telephone alert call, examined Plato crater. Although she did not 
     report C. Brook's slight mottled pink on the floor of Plato, she did 
     report through that the floor patches looked darker than normal, 
     especially in blue light and in red they were not visible at all. In 
     white light they were darker than normal. A.C. Cook was probably 
     observing at the same time via a couple of remotely controlled 
     telescopes in Aberystwyth. The results (time lapse imagery 
     through narrow band filters) will be examined at a later date.
     Note that this observation was made after C. Brook said that he could
     no longer see his TLP. Therefore this constitutes a different TLP
     as there had been a gap of 1 hour since the last TLP report.

     On 1974 Mar 3 at UT 19:06-20:20 J-H Robinson (Teighmouth, Devon, 
     UK, 10" refractor, x200, seeing=poor) got a Moon Blink reaction 
     on the South east wall of Plato, adjacent to the rim shadow and 
     alerted the BAA TLP network. Ford reported a negtive result at 
     19:35UT, although Robinson was still getting a blink reaction at 
     19:40UT, albeit fainter, red at times. Findlay at 19:43-19:52 
     and 20:00-20:05 saw nothing unusual. Robinson at 19:56UT no 
     longer saw a blink, but it returned at 20:05UT. Light in bothred 
     and blue filters. Not steady, but coming and going and gone at

     On 1988 Jul 24 D. Darling (Sun Praire, WI, USA, 12" reflector, 
     x150, S=7/10, T=3) observed the following in Proclus: "At 0213 
     the previously observed gray area was 1/3 of July 22 and V 
     shaped and fanned out across the floor. Could see hint of knot 
     seen before. Craters named in 7/23/88 (#319) were all normal 
     this time too". Is it possible that this report refers to the 
     crater "Gray" rather than "Proclus" as the column field suggests 
     in the Cameron catalog? The Cameron 1978 catalog ID=333 and

     On 1963 Nov 28 at UT 00:30-01:45 Barr, Greenacre, Hall and 
     Dungan (Flagstaff, AZ, USA, 24" refractor, and 69" reflector) 
     observed pink on the outer SW rim and a red spot towards the S of 
     this. A red spot was seen on the eastern side of Vallis Schroteri
     but only by Barr and Dungan. Other features checked for 
     atmospheric spectral dispersion and chromatic aberation - but the 
     colours in Aristarchus were not due to these. Smaller 12" scope 
     checked but no effects seen - presumably due to resolution and 
     image contrast issues? Pink on the SW rim may have been seen in a 
     69" scope by Boyce and Ford. ALPO/BAA weight=4.

2024-May-21 UT 05:55-07:40 Ill=95% Aristarchus observed by no on 1967-9-17

     Aristarchus 1967 Sep 17 UTC 02:05-02:21 Observers: Delano (Fall River, 
     MA, USA) and Corralitos Observatory (Organ Pass, NM, USA). The former 
     used a 12.5" reflector at 400x and the latter a 24" reflector. The NASA 
     catalog states the following: "A rimtop cratelet on SW rim appeared 
     almost as bright as c.p. thru a Wratten 25 filter (red) but no brighter 
     than a lower central wall & rim thru a Wratten 48 (blue) filter. Inner 
     W. slope of craterlet displayed a bright red color which became less & 
     less noticeable until 0212h It was no longer brighter than other parts. 
     At 0217 it flared again brighter red for 1m. (indep. confirm. of

2024-May-21 UT 06:11-07:42 Ill=95% Briggs observed by Grego_P on 2010-4-27

     On 2010 Apr 27 at UT 00:10-00:30 and 01:45-02:00 P. Grego (St 
     Dennis, UK, 20 and 30cm reflectors) noticed a craterlet just 
     to the east of Briggs and an E-W trending lineament or wrinkle 
     ridge that did not show on NASA LAC charts. Further checks did 
     not reveal it on Lunar Orbiter mosaics, but the craterlets 
     (and not the E-W trending ridge) were visible in LROC 
     topography data. The ridge is possibly a very low relief 
     feature that shows only under very shallow illumination 
     conditions. The ALPO/BAA weight=1 until we get confirmation at 
     repeat illumination.

2024-May-21 UT 08:01-08:05 Ill=95% Aristarchus observed by Louderback_D on 1983-9-20

     On 1983 Sep 20 at UT 05:08-06:13 Louderback (South Bend, WA, USA, 
     3" refractor, x150, seeing poor and chromatic aberation on the limb) 
     detected "purple"in the vicinity of Aristarchus crater and this was 
     stongest on the north and north west external rims, however there was 
     no "violet glare"from inside the crater. However the region of the 
     central peak was very bright - though he could not detect the central 
     peak. The brightness of the TLP was 4.5 and it should normally be 3 
     (nimbus area). Near the "big plain"it was 7. The chromatic aberation 
     seen on the crater. There was also violet on the northen wall of 
     Herodotus crater and the Cobra Head. ¤t appeared dark blue in the blue 
     filter", the surrounds remained gray". Apparently on the 26th the"ring 
     was still dark with faint violet - nearly normal". Cameron comments 
     that the TLP was due to spurious colour. The Cameron 2006 catalog ID=
     229 and the weight=3. The ALPO/BAA weight=2.

2024-May-22 UT 03:15-03:40 Ill=98% Plato observed by Braga_R on 2013-1-25

     On 2013 Jan 25 UT 19:05-19:15 R.Braga (Milan, Italy, 115mm 
     refractor, x267, seeing III, transparency average) observed that 
     Plato in general was normal in appearance, but the east rim was 
     showing a remarkable golden (yellow-golden) hue. This was a 
     repeat illumination observation for a W.E. Fox TLP observation 
     from 1938 Feb 14. The observer was wondering whether they were 
     in some way biased after reading the original report desription 
     - so uncertain over this being a TLP. In view of uncertainty 
     ALPO/BAA weight=1.


2024-May-22 UT 03:26-05:05 Ill=98% Aristarchus observed by Foley_PW on 1976-1-15

     Aristarchus 1976 Jan 15 UT 19:30-20:50 Observed by P.W. Foley 
     (Kent, UK, 12" reflector) - Aristarchus was abnormally bright 
     (Cameron suspects that this is a confirmation an explosion 
     effect seen earlier by Greenland: "On 1976 Jan 15 at 19:45Ut 
     Greenland (Crawley, UK, 7x50 binooculars) thought that they 
     saw an "explosion" on the Moon (in the general region of 
     Aristarchus) for a fraction of a second, followed by a bright 
     spot in the same position (not an astronomer). After 
     discussions with others, decided it was a moment of transition 
     to greater intensity (better seeing?). Moore thinks it was 
     atmospheric but says it should be on record. Cmeron's 1978 
     catalog ID=1425 and weight=5". For the Foley report: Cameron

     On 1977 Apr 02 at UT22:00-00:00 L. Fitton (Shaw, Lancashire, UK, 8.5" 
     reflector, x200, Wratten 25 and 44A filters, seeing II-III, 
     transparency, good) noticed in Aristarchus, blue to the north west
     (IAU?) internal wall, also blue observed in other small bright objects 
     against dark backgrounds. Lunar rotational axis and optical normal 
     related such that the normal runs NW-SE (IAU?) through these features. 
     Observer deduced that the coliur was obviously spurious and no blink 
     was seen in any feature. The blue disappeared as the lunar altitude 
     increased and no blue seen by 00:00UT. This is a BAA lunar section 
     observation. The ALPO/BAA weight=1.
