     magnitude in 2.5 hours - a photometric measurement. The average 
     magnitude for this age is 4.03, so therefore the crater had brightened 
     by two times above normal. The Cameron 1978 catalogID=769 and the 
     weight=5. The ALPO/BAA weight=3.

     observed 4th magnitude star-like flashes to blotches in Aristarchus, in 
     ashen light. Cameron says that this is independent confirmation and 
     also that the date in MBMW is 7/1/65 which is local time + 2nd UT. The 
     Cameron 1978 catalog ID=881 and weight=3. The ALPO/BAA weight=3.

     USA, 152mm refractor x248,S=2-3, T=5) "observed in White light and 
     through Wratten Red 25  and Blue #38A filters. The crater through the 
     Red 25 filter looked very similar to the view in White light. Using the 
     Blue 38A filter Picard almost dissapeared - it looked like a dim, 
     faintly observable black spot with the sunlit, east facing west crater
     wall barely visible. Observer had not observed Picard very often, so 
     was not too familiar with it but it seemed odd that it almost vanished 
     through the blue filter." ALPO observational report. The ALPO/BAA

     On 1972 Apr 17 at UT 20:10-20:45 Hvidore (Denmark, 2.5" refractor, x58, 
     x100, seeing=good) noted a brightening of the dark limb between 
     Hercynian mountains and Cleostratus crater. Thought that it was due to 
     atmospheric disturbance. Cameron says similar to other reports e.g. No.

     good and transparency = clear) observed south east of Plato at the foot 
     of Mt Blanc a small bright spot like a magnitude 4 star - slightly out 
     of focus. This bright speck remained unchanged for 30 minutes. The 
     Cameron 1978 catalog ID=137 and the weight=3. The ALPO/BAA weight=2.

     On 1847 Dec 11 at 18:00UT Hdgson (Eversley, UK, x80 refractor and 40x 
     reflector) observed in Plato (Though it might have been Cape Agassiz or 
     Teneriffe Mts) a bright spot of about a 1/4 the angular diameter of 
     Saturn that varied intermittently and was at all times visible on the 
     night side of the Moon. The following day he glimpsed the same spot 
     rhough clouds. From his drawing the spot was ~5' below the true N. 
     point & near the following limb (IAU E. limb) Cameron comments that 
     Plato fits the angular distance better than the other two candidates 
     unless there was a large northern libration. The Cameron 1978 catalog 
     ID=125 and weight=3. The ALPO/BAA weight=3.

2026-May-21 UT 20:42-22:02 Ill=32% Aristarchus observed by Brandli on 1969-5-21

     On 1969 May 21 at UT 20:00-21:00 Brandli and Germann (Switzerland, 6" 
     refractor) observed a slow orange-red blinking on the surrounding area 
     of Aristarchus. It was seen less markedly the next night. Wald (Zurich, 
     Switzerland) noted at 20:30UT that the crater was pink (Confirmation 
     says Cameron) - this was during the Apollo 10 watch. The cameron 1978 
     catalog ID=1131-1132 and weight=5. The ALPO/BAA weight=4.


2026-May-21 UT 21:12-22:02 Ill=33% Fracastorius observed by Robinson_JH on 1973-3-9

     Fracastorius 1973 Mar 09 UT ~19:57 Robinson (Devon, UK) saw a 
     Moon Blink (colour) in this crater. This crater is long 
     suspected of giving permanent blinks due to natural colour. The 
     ALPO/BAA weight=1.


2026-May-21 UT 21:29-22:02 Ill=33% Aristarchus observed by Pruss on 1969-7-19

     On 1969 Jul 19 at UT 1845-18:47 Pruss and Witte (Bochum, Germany, 6" 
     refractor x36 and binoculars) saw brightenings in the north west wall 
     of Aristarchus for 3-7 seconds of about 1 magnitude over the 
     background. From orbit at UT 18:46 the Apollo 11 crew Armstrong, 
     Aldrin, and Collins (in orbit around the Moon and using the naked eye) 
     were asked to take a look at Aristarchus after Earth-based reports of 
     TLP activity. Armstrong reported (after the solar corona had set, on 
     the night side) that probably Aristarchus "to be considerably more 
     illuminated than the surrounding area. It just has - seem to have, a 
     slight amount of flourescence to it". Collins reported a moment later: 
     "Looking out on the same area now. Well at least there is one wall of 
     the crater that seems to be more illuminated than the others. I am not 
     sure that I am actually identifying any phosporesecence, but that 
     definitely is lighter than anything else in the neighborhood". Houston 
     then asked if the crew could detect any colour and if the inner wall 
     was the inner or outer part? Aldrim  commnted that it was the inner 
     wall and Collins mentioned thatno colour was incolved. The Cameron 1978 
     catalog ID=1165 and weight=5. The ALPO/BAA weight=3.


2026-May-21 UT 20:16-22:04 Ill=33% Earthshine: sporadic meteors

2026-May-22 UT 19:29-20:16 Ill=43% Cepheus_A observed by Collins_M on 2000-10-4

     Cepheus A 2000 Oct 04 UTC 08:15-08:50 Observer: Maurice Collins 
     (New Zealand, 90cm ETX) - observer noted that crater was 
     extremely bright - wasn't sure if this was normal and at the 
     time rated it as the brightest (contrasty?) crater that he had 
     ever seen on the Moon. Many years later he suspected that he may 
     have mis-identified the crater. This still leaves us with thr 
     problem as to why a crater should be so bright in this region, 
     and if so, which one? ALPO/BAA weight=1.


2026-May-22 UT 20:40-22:26 Ill=43% Helicon observed by Novet on 1788-3-13

     Lunar volcano, seen on the dark side, as bright as a

     On 1969 May22 at UT2045-2105 Wald (Zurich, Switzerland) observed the 
     pinkish colour in Aristarchus was less marked tonight. The astronauts 
     were alerted and at 22:12 reported no activity but could see the crater 
     and Earthshine was strong near the terminator. Apollo 10 watch, 
     spacecraft far from the terminator. The Cameron 1978 catalog ID=1134 
     and the weight=2. The ALPO/BAA weight=2.


2026-May-22 UT 22:02-22:26 Ill=44% Atlas observed by Germann on 1969-5-22

     Atlas 1969 May 22 UT 21:20-21:40 Observed by Germann, Wild, Vieli 
     (Zurich, Switzerland, 6" reflector) "Rim towards the sun was bright.

2026-May-23 UT 19:30-20:32 Ill=54% Mare_Crisium observed by Williams_AS on 1882-3-26

     A.S.Williams of West Brighton, UK, using a 2.75" Acromatic refractor 
     (x75, definition good, but it was too windy to use the 5.25") noticed 
     that the mare was a mass of light streaks and spots. This was not 
     considered unusual, but these features were unusually plain, distinct 
     and brught, especially the streaks. The observer could not recall 
     seeing the streaks so bright and clear with this instrument before, and 
     indeed hardly ever with the larger 5.25" telescope. The observer 
     continued to observe Mare Crisium on many nights for several months and 
     comments that such an unusual exhibition was later seen perhaps once 
     every 2-3 lunations. They are uncertain how much this effect depends 
     upon the state of the Earth's atmosphere. This TLP does not make it 
     into the Cameron 1978 catalog and so may not be a TLP - however it has 
     been included, just in case, and to try to understand what was actually 
     seen. ALPO/BAA weight=1.


2026-May-23 UT 21:32-22:43 Ill=55% Mons_Piton observed by Smith_T on 2022-8-4

     Mons Piton 2022 Aug 04 UT 19:41-20:10 T. Smith (Codnor, UK, 
     16inch Newtonian, x247, Seeing IV) mountain was very bright 
     and red around its eastern slopes. An examination of the 
     bright and contrasty Proclus crater revealed that to be 
     relatively colour free compared to Piton. An examination of 
     other features, north and south along the terminator revealed 
     some tinge of coloiur but not as strong as on Mon Piton. Mons 
     Piton examined with a yellow filter at 19:50 and still showed 
     red along the eastern side, other features along the 
     terminator had no colour through the filter. Video images by. 
     A.Cook (Newtown, UK) made earlier at 1929 & 19:40 UT, (in the 
     SWIR (1.5-1.7 microns) did not reveal Mons Pico as especially 
     bright - but resolutioin was poor. A friend of Smith, phoned 
     up the next day to say that they saw a mountain on the limb 
     exhibiting red on the 14th August. Probably the redness was 
     due to atmospheric spectral dispersion as the Moon was low, 
     and it was especially visble on Mons Piton as this is an 
     exceedingly contrasty object on the terminator. ALPO/BAA 
     weight=1.

     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.

2026-May-24 UT 19:32-20:43 Ill=64% Plato observed by Bianchini on 1725-8-16

     A track of reddish light, like a beam, was seen
     crossing the shadowed floor of Plato.This TLP has an ID
     No. of 17 in Cameron's 1978 catalog and a weight
     of 3. It has an ALPO/BAA weight of 2.


2026-May-24 UT 19:32-20:38 Ill=64% Plato observed by Williams_AS on 1882-3-27

     Plato 1882 Mar 27 UTC 20:10-21:00 Observer: A.S. Williams (Brighton, 
     UK, 5.5" saw the shadow filled floor of Plato at Sunrise with a 
     "Glowing and curious milky kind of light". About 1 hour after sunrise 
     at Plato, there was no trace of this effect. The TLP filled the whole 
     floor except at a quarter of the diameter from the east wall which was 
     actually quite black. The observer saw a curious phosphorescent glimmer 
     at sunset (April11th?). Cameron comments that Birt, Nelson and Waugh 
     saw obsecuring mist or fog in Plato on many occasions. Cameron 1978 
     catalog ID=229 and weight=3. ALPO/BAA weight=3.

     reflector x240, seeing=3-6/10 and T=4) noticed "2 small high-sun areas 
     nr. Eimmart - brightening around Mare Crisium, except for interior of 
     Proclus - in blue light. They were brighter than 2 spots on Cap. 
     Agarum rated 8.5 & Proc. 9. Not as bright next night. Probably a real 
     blue light brightening". Cameron 2006 catalog ID=79, location on Moon:

2026-May-24 UT 21:04-22:53 Ill=65% Ross_D observed by Harris on 1965-9-4

     On 1965 Sep 03 UT03:00-05:00 D.Harris (Located near Whittier 
     College, Whittier, CA, USA, using a 10" f/8.2 Newtonian 
     reflector, x78 & x208, seeing 5-6, transparency 2-0) observed a 
     ridge obscured SSW of Ross D. No drawing was made, only a 
     written description. "Ridge not visible near crater; possible 
     white patch 1/3 Ross D diameter" The ridge is the wrinkle ridge 
     extending NNE from Ross D, a well established often visible 
     feature. Harris comments that this was not one of the better TLPs 
     seen near Ross D, and there were no independent observers, 
     neverless he was ceratin of this being a TLP, and it was 
     consistant with other activity seen near this crater between 1964 
     and 1970. Cameron 1978 catalog ID 891 and weight=3. ALPO/BAA

2026-May-25 UT 20:22-22:19 Ill=74% Tycho observed by Abel_P on 2009-5-3

     On 2009 May 03/10 UT23:20-00:11 P. Abel (Leicester, UK, 20cm reflector, 
     x312, seeing III-IV) observed that the north east wall was slightly 
     brighter than would have been expected, slightly blurred (not seeing 
     related blurring) and had a strong orange-brown colour. No spurious 
     colour seen elsewhere. A change in eyepieces showed the same effect. No 
     luck in alerting other observers. A drawing was made at 23:20UT and 
     finished at 00:12UT. At 23:12UT part of the inner NW floor had a dull 
     brown colour, whereas before it was grey.By 00:11UT the colour effect 
     was fading and by 00:18 seeing condirions were too bad to continue. M. 
     Cook (Mundesley, UK, 9cm Questar telescope, x80, x130, seeing III, 
     transparency moderate to good) had observed Tycho earlier in the 
     evening at 22:15UT, but had seen no signs of colour. W. Leatherbarrow 
     (Sheffield, UK, 8cm scope, high cloud interuptions and bad seeing) had 
     taken monochrome images at UT 20:07 and 20:10, but these showed nothing 
     unusual, and he checked the crater visually at 00:00-00:30, but 
     detected no colour, although the Moon's low altitude contibuted to poor 
     seeing conditions and some spurious colour was seen. CCD images from M. 
     Collins (Palmerston North, New Zealand) taken at 00:46UT showed 
     nocolour apart from spurious colour on contrasty edges, in no way 
     reflecting what was seen early by P. Abel. The ALPO/BAA weight=2.


2026-May-25 UT 21:59-22:57 Ill=74% Copernicus observed by Burt_G on 2006-6-5

     Observer made a drawing over a period of 30 minutes. Upon
     examining drawing, and comparing with photos made under
     similar illumination was struck by the abnormality of a
     a small white blob in the north east corner of the shadowed
     floor. There should be no raised topography between the wall
     and the central peaks that could give rise to this. The making
     of the sketch overlapped with an earlier drawing made by Rony
     de Laet (Belgium) which did not show this blob. Subsequent attempts
     to find sketches/images at very similar illumination angles have
     failed to show the blob in the north east corner of the chadowed
     floor. ALPO/BAA weight=3.
