2018-May-01 UT 00:00-03:45 Ill=99% Aristarchus observed by Moore_P on 1977-7-1 *

     P Moore, Selsey, Sussex, UK, used a 5" x250 scope and between
     23:50UT on Jul 1st 1977 and 00:10UT on Jul 2nd 1977 observed
     Aristarchus. The south wall of the crater was reddish, extending 
     down to the outer south east wall (IAU). However seeing was no 
     better than III-IV and he was 99% sure that the colour was 
     spurious. His report was submitted only in case any other 
     observers reported something similar. ALPO/BAA weight=1.


2018-May-01 UT 00:43-02:27 Ill=99% Aristarchus observed by Mellor on 1978-5-22

     Aristarchus was not normal, but all the following features were: Mare 
     Crisium, Proclus, Sinus Iridium, Grimaldi, and Tycho. Observed by 
     Mellor and Fitton, UK. Observer notes that Aristarchus is brighter than 
     Tycho when normal. Estimated variation was 25%. However the Moon was 
     low and the Moon was yellow. Despite this the observer decided that the 
     effect was real. Cameron 2006 extension catalog ID=32 and weight=2.

     that the central peak of Aristarchus was quite bright and extended to a 
     circular region in the east in the crater "sprout" area - Cameron 
     suggests that this is Bartletts self defined EWBS area?. Beyond the rim 
     to the east was very bright. However no colour effect was seen in

     12.5" reflector at x300-400 - seeing IV) saw colour in Aristarchus (red 
     on the south east wall and southern "horn" of the crater. He could not 
     detect colour elsewhere, but felt that the effect might have been 
     spurious colour. With the increasing altitude of the Moon the light 
     effect decreased. Moore detected red the next night as well (May 25th) 
     and on May 27th, but it was not present on May 29th. The Cameron 2006

2018-May-03 UT 00:55-01:27 Ill=91% Cleomedes observed by North_G on 1993-9-3

     Cleomedes Alpha 1993 Sep 03 UT2200-22:20 G. North (UK, 18.25" 
     reflector, x86 & x144) observed it to be a strikingly brilliant 
     'splodge' seen in the mostly shadow filled interior of 
     Cleomedes, and around this splodge was a faint halo extending 
     symetrically in an eastwards direction. The splodge was the 
     mountain Cleomedes Alpha. Strangely no shadow from the mountain 
     was seen to be cast onto the halo on the east. Observer alerted 
     other observers by phone, and upon returning to the scope found 
     that the splodge had faded in brightness and continued to fade 
     over the next hour as one would expect from a mountain at 
     sunset. Some heavy spurious colour was present. J. Cook & M. 
     Cook (Frimley, UK) observed at 22:20-22:25 and found the bright 
     splodge, but no halo. M. Cook re-observed later and confirmed 
     normal fading of splodge. Roscoe observed from 00:30UT next day, 
     but by that time Cleomedes Alpha had set and was no longer 
     visible in the shadow filled floor. S. Beaumont had observed 
     earlier at 20:00 but had recorded all as normal in Cleomedes.

2018-May-05 UT 03:01-04:02 Ill=77% Posidonius_J observed by Holt_D on 2008-10-19

     On 2008 Oct 19 during 05:40-06:30UT D. Holt of Chipping, UK observed an 
     anomalous patch of illumination just to the west of the centre of the 
     Posidonius J crater. It is possible that this is just some high ground 
     on the floor protruding through the shadow filled crater at sunset. 
     Therefore this has been assigned a weight of 1 for now, just in case it 
     is a TLP - until proven otherwise.


2018-May-06 UT 03:37-03:52 Ill=68% Hansen observed by Androsan on 1973-10-17

     x230) observed a glow 1-2 sec reappearance of Saturn's rings at a place 
     of ring's appearance on the dark limb. The observers attributed it to 
     Saturn and its rings. Cameron speculates that it might be due to gas or 
     dust at the lunar surface. Eye was attacted to the glow which 
     delineated the limb at a position angle of 210 deg at emersion, at

     A faint white pinpoint flash seen and also in the same position
     a whitish glow around the crater. No futher flashes seen after the
     first one. From UT2117-2130 the glow was still visible but faded
     making it more difficult to locate. When Foley observed he found 
     Aristarchus not very visible in Earthshine, despite Plato, Grimaldi,

2018-May-22 UT 20:05-22:02 Ill=58% Proclus observed by Darling_D on 1989-12-5

     On 1989 Dec 05 D. Darling of Sun Praire, WI, USA, saw two dark spots on 
     the SE floor of Proclus. The first dark spot was seen through  3" 
     refractor and then also through a 12.5" reflector (35x and 154x). 
     Seeing was S=10 and T=5. He noticed that at 23:00UT the wall spot was 
     less well defined. Darling also comments that he observed reflecting 
     glint, almost as if from a glass surface - he had not seen this effect 
     before. A telephone alert was issued and Caruso verified the spots. 
     Cameron comments that the spots were not shadows because the Sun was at 
     an altitude of 52 deg at Proclus at the time and she states that the 
     steepest slope ever mesured on the Moon was 52 deg and not inside 
     Proclus. Other observers observing were: Weier (6.5" refractor x284 and 
     S=3/10), Caruso (8" reflector x100), and Cameron. The Cameron 2006

     of the observers or the two features reported as having TLP on that 
     night. On 1984 Feb 12-13 Marshall (South Anerica, seeing=III-II) saw 
     initially no craterlets in Plato, despite the Moon being at a high 
     altitude. At 01:45UT the northwest corner of Plato was red. Again no 
     other craterlets showed. He found the surrounding wall to be too bright 
     and this was confirmed by Crater Extenction Device readings and had 
     problems focussing on the crater. By 02:00-02:50UT he noticed 
     variability in the visibility of the craterlets. By 03:48UT the central 
     craterlet was much brighter than before and the crater doublet had 
     brightened but the southern craterlet was still invisible. Cameron 
     comments that Marshall was a very experienced observer. A. Cook (of 
     Frimley, UK) obtained a photodiode line scan image of Plato. The 
     brightness of the north west wall was brighter than the bright area on 
     the west wall. Marshall and Mosely both saw a dark area on the floor of 
     Plato close to the south wall (from clock position of 11 o'clock. There 
     was a prominent white spot on the floor and the central craterlet was 
     seen, but only under good conditions. Mosely does not discuss the west

     On 1980 Apr 28, Louderback (South Bend, WA, USA using a 8" reflector 
     and a 2.5" refractor) observed a very bright reg region on top of the 
     south west rim of Aristarchus crater. This was on the same side as the 
     ray system between Aristarchus and Herodotus. Louderback noticed some 
     chromatic aberation - blue where he had seen the red patch before.
     Louderback suspects chromatic aberation was the cause although did not 
     see red in that region ever again. "Patch was between his observation 
     points A and C. Point C was 5 points brighter in the red filter than in 
     the blue." A sketch was made. Cameron suspects that the TLP was real.

2018-May-30 UT 01:29-02:11 Ill=100% Aristarchus observed by Darling_D on 1989-10-15

     David Darling observed bright glittering on Aristarchus. This
     was followed by a flare up in brightness at 00:38:05 UT in the
     comet-like ray area of the crater equivalent in intensity to the
     central peak. Then he saw another one on the north east rim of 
     Aristarchus of the same brightness. A third flare was seen at
     00:49UT in south of Herodotus, on the comet-like ray. Another
     two flares were observed at 00:56UT on the north west rim of
     Aristarchus. Darling suspects that these effects were due
     to seeing effects and Cameron agrees. However Weier suspects
     that they were TLP? Brightness measurements by Weier were for
     the south west rim of Herodotus 8.0, for a spot at the Cobra's
     Head 9.0 and 7.5 for C.H. Cameron apparently did not see the flashes
     but did suspect that the interior of Aristarchus was a bit unusual. 
     Don Spain did not see anything unsual at all. Cameron 2006 extended
     catalog ID=380 and the observation weight=3. The ALPO/BAA weight=2. 


2018-May-30 UT 01:59-02:11 Ill=100% Herodotus observed by Kilburn_K on 1971-12-2

     (Manchester, UK, 8" refractor, x130, Transparency very good 
     with a thin mist, seeing excellent, x130). Bright point 
     (considerably brighter than its surroundings) was seen on the 
     SE of the illuminated floor of Herodotus in white light. It 
     was quite close to the crater rim. The spot had no colour.

     Proclus 2002 Mar 29 UT 05:27-05:36 Observed by Darling (Sun Praire, WI, 
     USA, 12.5" f/5 Newtonian, +Rotating polaroid visual densitometer) 
     "Observations made following telephone alert call about Brook's report. 
     Aristarchus, Proclus and Censorinus monitored for brightness variations 
     from 04:41-05:37UT. Apart form a change in transparency due to cirrus 
     cloud at 05:11-05:18, there were significant dimmings of the 
     brightnesses of Proclus at 05:27. Aristarchus remained constant - this 
     suggested that Clive Brook's earlier report was not a TLP in 
     Aristarchus, but possibly in Proclus which he was using as a 
     comparison" ALPO Lunar Section Report. ALPO/BAA weight=3.
