2018-May-01 UT 00:00-03:11 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 00:43-01:02 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. 
     ALPO/BAA weight=1.

     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

     On 1980 Apr 19 at UT20:30-22:59. The following is quoted from the 
     Cameron 2006 catalog.... "(Buczynski) alerted by colleague (Greenwood) 
     who used filters W15 (IR), W25 (red), W44A (blue), & W58 (UV) and had 
     located a possible blink in it. (Bucz) used W15, W44A & W25. C.P was 
     very bright in W25 (red), dull but vis. In W44A (blue) & floor was 
     noticibly darker in W44A than in W25. Bright cp vis. In W15 & floor was 
     of a light shade. Other craters checked for color, none found. In 44A 
     floor lost some definition (gas?). Sketches from Bucz. & Greenwood. 
     (Pedler) at 2140, floor area around cp was seen in white & red as 
     normal but blink was vis in white, darker in blue. Checks of other 
     features were negative. (Amery) small dark center & small dark area - 
     not shadow - under S wall. N wall obscured by dark area extending N 
     onto surrounding mare. (normal?) which was difficult to focus (gas?). 
     At 2155 N wall now sharper & dark area less intense. Craterlet Cameron 
     in N wall clearly seen which was invisible 1/2 h earlier. (Saxton) 
     whole crater flashed and blinked at 2155. Could see detail in brighter 
     W 1/2 of crater - not seen earlier. At 2205 seeing poor, at 2215 it was

2018-May-20 UT 18:26-19:01 Ill=34% Fracastorius observed by Robinson_JH on 1980-4-20

     On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teighmouth, UK, 10.5" 
     reflector, x180) found, using a Moon Blink device, evidence of colour 
     on the flor patches of Fracastorius crater, brighter in blue than in 
     red. Also the floor to center varied in brightness in blue and in red. 
     Peters observed in white light and found the south east-south wall had 
     a slight orange cast and when a Moon blink was used it was less bright 
     in blue than in red light. M. Cook found spurious colour on the south 
     rim and also on Mons Pico. There was a colour blink reaction on the 
     southeast floor of Fracastorius - this was both faint and blurred and 
     not seen in white light. A.C Cook detected the permanent blink in the 
     south east floor of the crater at 21:47 and a fainter one in the north 
     west (marginally brighter in red than in blue). J.D. Cook found no 
     colour with the Moon blink device. 21:22-22:10 P.W. Foley got a strong 
     colour reaction with the Moon Blink device - brighter in red than in 
     blue and detected a pink colour visually on the south east wall 22:10-
     22:45 (this did not give a blink effect though). Cameron 2006 catalog 
     ID=88 and weight=4. ALPO/BAA weight=2.

     On 1980 Apr 20 at UT21:38-21:50, Blair of Renfrewshire, Scotland (used 
     an 8" reflector and seeing=III) saw three patches in Petavius and they 
     could still be seen 7 minutes later. At 21:50UT he used a filter and 
     found the "northern one was brighter in blue, the southern one was 
     brighter in red and the central one was the same shad ein both 
     filters." Cameron comments that the central patch was a permananent 
     one. She then goes onto say that the crater is described as having dark 
     patches that are opposite to what one would expect from Fitton's theory 
     applied to dark features. Cameron 2006 extension catalog ID=88 and 
     weight=4. ALPO/BAA weight=3.

     On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a 
     10" reflector at 32-64x) noticed that Aristarchus was not 
     visible, although the Earthshine was very obvious. Foley (of 
     Kent, UK, and using  12" reflector) noticed that the crater was 
     only just visible but Plato could definitely be seen. Cameron's

2018-May-22 UT 18:28-18:33 Ill=57% Alphonsus observed by Lenham_AP on 1952-11-24

     Alphonsus 1952 Nov 24 UT 18:00 A.P. Lenham (Swindon, UK, 3-
     inch efractor x120) noted that the usual dark spots were not 
     visible, but floor ridges and craterlets were surperbly seen. 
     This may not be a TLP but has been given a TLP category as it 
     is a curious appearance and needs to be verified on a repeat 
     repeat illumination apeparance. ALPO/BAA weight=1.


2018-May-22 UT 18:28-19:15 Ill=57% W_Limb observed by Miles_H on 1987-1-7

     On 1987 Jan 07 at UT19:10-20:30 H.Miles of Cornwall, UK saw two bright 
     patches were seen in Earthshine at clock positions of 4 (this patch was 
     defined by the dark limb and the brightness faded inwards to the disk, 
     over a short distance. "Centred at 60 deg along the limb from the north 
     - a sketch showed approximately 10-15 deg along it") and 5:30 (this 
     second patch was smaller and not so bright as the first patch - it was 
     west of the north pole. P. Foley (Kent, UK) also detcted the patches 
     and said that one was not far from the sunrise terminator. 
     The Cameron 2006 Extension catalog gives this TLP an ID of 291 and a 
     weight of 2. The ALPO/BAA weight=2.

2018-May-22 UT 19:35-21:20 Ill=57% Werner observed by Lippert_RM on 1953-9-16

     On 1953 Sep 16 UT03:00 R.M. Lippert (San Diego, CA, USA, 20cm 
     Cassegrain reflector, x90)saw a bright magnitude 1 flash on the 
     Moon, that was probably on the east rim of Werner(?) crater. It 
     is unclear if the observer meant it was really magnitude 1, or 
     was what a magnitude 1 star would have looked like. The flash 
     was yellow-orange in colour. Observation described in the 
     "Observations and Comments" column in the December, 1953 
     Strolling Astronomer (Vol. 7, No. 12), on page 170. The ALPO/BAA 
     weight=3.

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 
     catalog extesnion ID was 382 and the weight=1. ALPO/BAA weight=3.

     immediately to the west was a dark (intensity 1.5-2) region extending 
     almost to the foot of the bright inner wall and very diffuse in 
     outline. The observation could not be followed through due to 
     increasing cloud, but on the following night all was normal."

     when first looking at the crater, but as time progressed the 
     effect became less bright. Other craters were checked for 
     similar coloured tints, but none were seen elsewhere on the 
     Moon. UAI observers in Italy (F. Taggogna & A. Tonon) had been 
     imaging the region in colour 17:57-21:47, but their images do

     Two telescopes were used and the bigger of these revealed some shading 
     on the floor of Proclus approximately a third as intense as he had seen 
     the previous night. A sketch was made. The TLP finished by 22:34UT. 
     Cameron comments that the dark patches could not be due to shadow as 
     the altitude of the Sun was too high at proclus. The Cameron 2006

     the western wall of Eimmart (sketch supplied) have an unusual 
     brightening and shade. Variations occurred over 2-3 minute intervals. 
     Louderback commented that the spot looked like a flare with its apex 
     located at the crater wall and there was some blurring effect on the 
     spot - it decreased in size during the phenomenon. Seeing worsened 
     later. Apparently on the 18th and 19th of April everything was back to

     Plato 1982 Jun 02 UT 22:00. Mobberley could not see the 
     central craterlet on the floor of Plato tonight. Foley notes 
     that he could only just see the central craterlet on nights of 
     2-5th Jun and it was of reduced in brightness from normal. 
     North reported that the floor seemed nearly black, but 
     brighter in a green filter (x144 magnification used). All

     On 1984 Feb 14 P. Moore (Selsey, UK) observed that Plato was darker 
     than the nearby mare and no detail could be seen on the floor or the 
     eastern wall - the later was obscured. At 23:40UT some dimming was 
     still present on the north east wall and still no detail on the floor 
     of Plato. Cook noticed that the eastern floor close to the wall was 
     misty and also noted no detail on the floor. Amery though noted that 
     all parts of the floor were sharp although some darkening was visible 
     in the north west and a hint of obscurtion. The east wall though was 
     quite sharp. Mosely could see the central craterlet but from 8-6 
     o'clock tricky to define (Foley says that this effect has been seen at 
     this colongitude before). Streak ray across the floor of Plato seen

     Aristarchus floor (point F) brightened rapidly from an intensity of 5.2 
     to 6, however at 07:08 UT the spot returned to normal. He also noticed 
     that the bands on the walls varied every few minutes. A mist like 
     appearance was seen on the floor of Aristarchus. Through a red filter 
     he could see through the haze, but floor detail could not be seen
