2018-May-01 UT 00:00-03:23 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-18 UT 19:46-20:03 Ill=15% Taruntius observed by Madej_P on 1980-4-18

     Taruntius on 1980 Apr 18 UT 22:33 P.Madej (Huddersfield, UK) 
     noticed that this crater changed from dark black to almost a 
     light grey over a period of about 30 seconds. Observation 
     started at 22:27 and ended at 22:37. When the observer saw this 
     effect in that 10min period is not given, so the UT above is the 
     nid UT of the observing period. The ALPO/BAA weight=1.


2018-May-18 UT 19:46-20:03 Ill=15% Aristarchus observed by Mobberley_M on 1981-5-7

     On 1981 May 07 at UT20:30-21:20 M. Mobberly of Suffolk, England (14" 
     reflector - seeing=poor and transparency=poor) P.W. Foley of ---- saw 
     faintish yellow-brown streaks in Aristarchus. Apparently these had been 
     seen the previous night, but were much fainter tonight. Bartlett had 
     previously seen this effect on the southern floor of the crater 
     according to Cameron. The Cameron 2006 catalog extension ID No. is 133 
     and the weight=3.

2018-May-20 UT 20:58-21:38 Ill=35% Aristarchus observed by Cook_JD on 1981-3-11

     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,
     and several other features being visible. Both observers used
     12" reflectors. Cameron's 2006 catalog Extension ID=124 and 
     weight=0. 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 19:55-21:20 Ill=58% 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

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.

2018-May-22 UT 20:31-22:25 Ill=58% Curtis observed by Williams_AS on 1882-8-21

     Williams of the UK, on 1882 Aug 21 at 19:30UT (Moon's age 7.9 
     days) noticed a spot at least half as bright, and as large as 
     Picard, near to Picard crater. This observation was reported 
     in the Astronomical Register of the Royal Astronomical Society 
     and is not included in the Cameron catalogs. It is one of many 
     measurements of the brightness of this spot for different 
     illumination angles and is one of three outlying brightness 
     points spotted on a graph by Willaims. The ALPO/BAA weight=3.

     On 1981 May 12 UT 22:00? M.C. Cook (Frimley, UK and using a 12" 
     reflector), noticed that Censorinus was very bright, fuzzy and 
     occasionally brighter than Proclus. However both Foley (Kent, UK) and 
     Amery (Reading, UK) using a C.E.D. found that Proclus was brighter than 
     Censorinus as it had been during April and May 1981. However Chapman 
     obtained the reverse of this. Cameron 2006 extension catalog ID=138 and 
     weught=3. ALPO/BAA weight=2.

     On 1989 Dec 06 at 23:09-23:34UT D. Darling of Sun Praire, WI, USA (3" 
     refractor x36 and x90, and then a 12.5" reflector at x64, S=7/10 and T=
     4, saw dark spots in Proclus (not as dark as those from 5th Dec 1989). 
     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 
     extension catalog ID=383 and the weight=0. The ALPO/BAA weight=2.

     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 
     three observers compared the Plato area to other areas for 
     reference. All the above seems normal, apart from the floor
     being brighter in the green filter. Cameron 2006 extension

2018-May-26 UT 20:03-21:23 Ill=92% Deslandres observed by Penzel_E on 1965-5-12 *

     On 1965 May 12 at UT 19:10 E. Penzel (Rodewisch, East Germany) was 
     taking a sequence of images during the impact of the Soviet Lunik 5. He 
     detected a tens of km scale elongated cloud after the impact over a 
     duration of 9.5 minutes. However there are differences between the 
     images elsewhere on the Moon, possibly due to different exposures or 
     some other effects and it is not 100% sure that what he detected was 
     impact debris/cloud?. The ALPO/BAA weight=3.

2018-May-26 UT 20:05-20:10 Ill=92% Aristarchus observed by Hobdell on 1981-4-16

     Hobdell, of St Petersburg, FL, USA, using a 2"? refractor?
     and Seeing=I-II, saw a bright region on the north west wall
     that seemed to change in brightness. In truth, there were
     other features elsewhere on the Moon that also fluctuated,
     but not as much as Aristarchus was. No colour was noticed.
     Cameron suspects fluctuations in our own atmosphere.

     On 1988 Jan 02 at 06:41-07:08 UT D. Louderback (South Bend, WA, USA, 
     using a 8" reflector, seeing 4 out of 10) observed that at 06:56 UT 
     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 
     through a blue filter. Cameron 2006 extension catalog ID=316 and
