     was apparently lighter than the rest of the floor and this was seen at 
     both low and high magnifications. Foley notes that this was unusual. 
     There were three craterlets visible on the floor - the central one was 
     the brightest. Cameron 1978 catalog ID=178 and weight=3. ALPO/BAA

     On 1982 Aug 11 at UT03:30-04:15 Mobberley (Suffolk, UK) obtained a 
     photograph and made a sketch that revealed a needle-like shadow from 
     the west wall to near by the central craterlet - the latter was quite 
     clearly visible. What were not visible were the other four craterlets. 
     The Cameron 2006 catalog ID=183 and weight=4. The ALPO/BAA weight=2.


2020-Jul-12 UT 02:34-03:40 Ill=58% Aristarchus observed by Sage_VA on 1978-10-23 *

     Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK, 
     10.25" reflector, x250, Wratten 44a and 25, seeing II) noted 
     that Aristarchus was surrounded by a dark area in the blue 
     filter. They did not regard this as a TLP at the time. However 
     because Aristarchus is surrounded by blue material in real life, 
     this should have been brighter? For this reason, despite the 
     observer regarding this as a negative TLP, an ALPO/BAA weight=1 
     has been applied.


2020-Jul-13 UT 02:39-03:41 Ill=49% Plato observed by Arsyukhin on 1981-12-19

     On 1981 Dec 19 at UT 01:00-05:00 E.V. Arsyukhin (Moscow, Russia, 3"

     158mm reflector, x72 and x110, seeing II, transparency fair?) 
     saw a small circular area of grey or white in the dark south end 
     of Copernicus.The area showed up better through a Wratten 15 
     yellow filter, but was not seen at all through a purple Wratten 
     35 filter. P.W. Foley (Kent, UK), confirmed this but thinks that 
     it is normal. Cameron 2006 catalog ID=68 and weight=1. ALPO/BAA 
     weight=1.


2020-Jul-14 UT 01:56-02:51 Ill=39% Earthshine: sporadic meteors

2020-Jul-15 UT 03:42-03:43 Ill=30% Limb observed by Dunn_S on 1762-6-16

     Closest parts of the Moon at Saturn appearing from
     occultation were dull and hazy. Was this an effect of
     the lunar atmosphere or a high haze and halo around the Moon?
     Cameron's 2006 catalog extension gives this an ID No. of 3
     and a weight of 1. The ALPO/BAA catalog weight is also 1.

     rise time, 1 hour delay time with 10 times increase in 
     intensity. Molecular weight was between 14 and 20. Could have 
     been Ne, Fl, O or H2O - the latter was thought best by 
     Freeman. Duration of event 13 hours. The Cameron 1978 catalog 
     ID-1284 and weight=5. The ALPO/BAA weight=5.

     On 1986 May 05 G. North (Herstmonceux, Sussex, UK, 30" reflector) found 
     that the crater (floor?) Plato was featureless, even during the better 
     moments of atmospheric seeing conditions. A spectra was taken but 
     nothing unusual was seen. The Cameron 2006 catalog ID=284 and the 
     weight=1. The ALPO/BAA weight=1.

2020-Jul-27 UT 19:33-19:58 Ill=53% Adams_D observed by Smith_T on 2019-9-6

     Adams D On 2019 Sep 06 UT 21:44-22:20 T. Smith (near Great 
     Yarmouth, UK, 90 mm Maksutov, x80, Seeing IV) saw a very 
     bright spot on the SW. rim of Adams D - at first sight looked 
     perhaps raised above the lunar background, but this was just 
     due to its brightness. It was by far the brightest object on 
     the NW quadrant of the Moon. In terms of brightness it was 
     almost but not quite bright as Proclus, but only half the sie 
     of Proclus. No colour was seen to the spot. The spot was not 
     emitting any false colour, there was no change in appearance, 
     and there was no ray structure visible either. Observations 
     ceased when the Moon got too low. ALPO/BAA weight=1.

2020-Jul-28 UT 19:32-19:34 Ill=65% Plato observed by Foley_PW on 1975-4-19

     On 1975 Apr 19 UT 21:09 P. Foley (Kent, UK), detected blue in 
     Plato on east. Fiton at UT20:45 found blue along the south wall 
     at the east (IAU?) end, which was very bright white. Blueness 
     extended towards the large landslip at the east of the formation. 
     Immediately north of the landslip, where the bright wall curves 
     first westwards, then again northwards, red could be faintly 
     detected, folloowed by a very faint blue. All other parts of the 
     formation were normal. Examination with a Moon blink device 
     revealed no colour blink. J-H Robinson also found blue, with red 
     on the west wall (exterior?). By 21:30UT Fitton found Plato to be 
     normal and so was Proclus, though he did find Epigenes (bright 
     cresecent of east wall only) slightly blue to the N.W and red 
     to the S.E. Mare Crisium was normal. Prominent spurious colour 
     seen on Venus, but it was low in the sky, with blue to the north 
     and red to the south. However J.H. Reading, managed to see the 
     north east floor blurred and slightly blue from 22:45-23:00UT. 
     These reports are BAA observation. The ALPO/BAA weight=2.

     Plato 1966 Jun 27 UT 21:40-21:55  Observed by Robinson (Teignmouth, 
     England, 10.5" reflector) and Sartory (England, 8.5" reflector + Moon 
     blink) "Color (red?) on SE wall detected by Eng. moon blink sys. 
     (confirm)." NASA catalog weight=5 (very high). NASA catalog ID 949.


2020-Jul-31 UT 19:27-22:17 Ill=91% Plato observed by Foley_PW on 1983-7-21 *

     On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector, 
     seeing=III) found the region around the cleft on the souther rim to be 
     out of focus - however atmospheric conditions were turbulent until 
     23:18UT. An unsual dark triangular region (long base against rim) was 
     seen to extend from the inner rim at 12 o'clock onto the floor for 13-
     16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK) 
     found the south east to soth west to be obscured again, but not as 
     badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the 
     dark region had 2 white bands on the side and the south west wall was 
     blurred like it was on the 20th July - this time tough colour was not 
     present. There were also two light patches on the floor. Mosely 
     (Coventry, UK) observed the south wall at x120 and found the wall out 
     of focus at the 11 o'clock location. Through a yellow filter he saw a 
     "white mistiness: on the top of the southern rim and only the south 
     east cleft could be seen (no colour). By 22:40-23:00 the effect had 
     cleared up. No dark triangular patch was seen. When Marshall (Surrey, 
     UK) observed (22:30-03:00) nothing unsual was seen, though a sketch 
     provided shows a light patch on the floor located at 11 o'clock. All 
     observations, made by all observers had some atmospheric turbulence, 
     however trsnparency was good. The Cameron 2006 catalog ID=225 and the 
     weight=5. The ALPO/BAA weight=3.


2020-Jul-31 UT 22:23-23:59 Ill=92% Herodotus observed by Bartlett on 1966-6-30 *

     Herodotus 1966 Jun 30 UTC 03:10-03:35 Observed by Bartlett (Baltimore, 
     MD, USA) described in the NASA catalog as: "Bright pseudo-peak again 
     vis. within floor shadow. Peak est. 5 bright. Had seen it at successive 
     lunations in '66" 4" x280 refractor used. NASA catalog weight=4 (high).
