     Theophilus 1969 Jul 21 UT 19:30-21:45 and 21:00-22:00 Observed by Fox 
     (Newark, England, 6.5" reflector,) and Baum (Chester, England, 4.5" 
     refractor) (S=6, T=4) "At wall, adjacent to Cyrillus was a redish glow,
     then obscur. (Fox). Baum  saw intermittant white-blue shimmering as if 
     glowing thru dust glowing & upsurge in brightness on c.p. Gradually 
     faded to normal at 21:20. 1st time ever seen by him tho. obs. since 
     1947. Image sharp, no haziness. (indep. confirm. of activity, but

2025-Aug-01 UT 11:24-12:35 Ill=50% Promontorium_Agassiz observed by Green_J on 1991-5-21

     On 1991 May 21 at UT05:30-06:15 J. Green (Orangevale, CA, USA, 11" 
     reflector) photgrapphed a broad bright band stretching east and north 
     of Cassini crater in 3 exposures taken 10 minutes apart. This 
     photographic sequence shows a gradual widening towards Cassini and by 
     the 3rd exposure the band is touching (and then obscuring) Cassini. A 
     "fan" was visible in the north east and WSW directions, later this was 
     seen as rays and this was even seen in the view finder of the camera. 
     Cameron comments that this might be lens flare but suspects that it 
     would not have been seen in the view finder. The Cameron 2006 catalog 
     ID=427 and the weight=5. The ALPO/BAA weight=2.

     (Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV) 
     Orange discolouration seen on ESE crater floor. Moon blink 
     tried, but no blink detected. By 21:10 the effect had lessened, 
     but was still orange. By 21:50-21:58 the effect was smaller and 
     perhaps more on the SE of the floor. Colour confirmed by Foley. 
     Fitton may also have been observing. At 22:00 A.C. Cook observed 
     and commented that a darkish, perhaps brown-orange colour seen - 
     but suspected it was probably spurious colour - but by now the 
     seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of 
     several features, including Theophilus, had not noticed anything 
     unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect 
     a blink, but noticed intermittent darkining on the shaded area 
     on the E. floor, but seeing was now IV. The darkening was more 
     noticeable in blue than red light. BAA Lunar Section

     that filled about half of the eastern half of the crater floor. To cut 
     down the glare a blue filter was then used and a slightly less dark 
     area was seen extending from this in a southerly direction. 8 rays were 
     seen. The dark patch was confirmed by Patrick Moore. However David 
     Darling (USA) who observed a few hours later on 1989 Jul 14 at 03:28 UT

2025-Aug-06 UT 12:00-13:51 Ill=91% 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.

2025-Aug-10 UT 20:52-21:06 Ill=97% Aristarchus observed by Moore_P on 1992-5-19

     On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector, 
     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 
     other features revealed colour. The Cameron 2006 catalog ID=446 and the 
     weight=0. The ALPO/BAA weight=1.

     On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector, 
     x260) noted that the southern slope of Mons Pico had a tint of colour. 
     No other features revealed colour apart from Aristarcus, where a TLP 
     was going on. The Cameron 2006 catalog ID=446 and the weight=0. The

2025-Aug-11 UT 14:20-14:29 Ill=94% Messier_A observed by Moore_P on 1951-8-20

     Messier A 1951 Aug 20 UT 01:48-03:00 Observed by P.Moore 
     (England, 8.5" reflector, x350). Bright cloud like circular 
     patch seen on S wall of Messier A. It was the brightest object 
     in the vicinity. Observations ceased due to the Moon setting 
     behind a tree. W.Haas thinks that this effect is not unusual at 
     similar colongitudes. Moore checked again under similar 
     illumination and still considers the Aug 20 appearance abnormal.

     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?

     unusually bright and shows up as a bright white spot on his

2025-Aug-18 UT 18:41-18:54 Ill=22% Moon observed by Darling_D on 1979-9-16

     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

     (Brixton, UK, 22cm Newtonian reflector, x64, x104, seeing IV). 
     Found Briggs A to be brownish in colour at x64, however the 
     colour vanished at 06:55 when x104 was used. Switching back to 
     x64 the colour was still there but fainter. The colour fade may 
     have been due to day light glare encroaching? Could not see this 
     effect anywhere else on the Moon but did detect what he regarded 
     as a permanent coloured spot (yellow) between Cruger and 
     Grimaldi. ALPO/BAA weight=1.

     Aristarchus as a vry bright 7-8th magnitude star in the dark part of

     in brightness of Mons Piton point D (his designation) during 04:56-
     04:59. The whole of the east slope was affected - initially bright and 
     then faded and there was a blue colour (detected with filters). The 
     variabilty was 8-11sec (Cameron suspects atmosphere as the altitude was 
     low). The brightness stabilized at 05:12UT, but variability resumed 
     until observing finished. As a comparison Aristillus was not seen to 
     change. The Cameron 2006 catalog ID=287 and the weight=1. The ALPO/BAA
