     Amery (Reading, England) saw blue in Aristarchus but a photograph did 
     not show the colour. Foley thinks this was spurious colour. Cameron

     north facing slope. The area concerned was diffuse and varied 
     in density despite the surroundings not varying. Foley notcied 
     no colour elsewhere on the Moon, though Amery thought that he 
     saw some in Aristarchus, but Foley thinks this was spurious.

     On 1982 Jun 05 at 22:00? UT, Chapman (UK, using a 12" reflector), again

     be seen between June 2 to June 5 and was much less discernable than 
     during the previous lunation. No CED brightness measurements made. The 
     floor of Plato was noted to be very dark though. Cameron 2006 catalog

     crater. This is probably normal, but we are flagging this up 
     as a weight 1 TLP, in order to obtain some repeat illumination 
     observations and confirm that the strength of the blueness is 
     normal.

     On 1898 Jan 08 at UT 00:00-01:00 Chrevremont (France?) notcied that 
     during a lunar eclipse, the mid-eclipse shadow was so dark that details 
     of the surface disappeared, all except for the Tycho SSW ray . Cameron 
     comments that it is unsual for that ray to remain when usually the ones 
     towards Kepler and Aristarchus are the ones to stand out? The Cameron

     On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor, 
     seeing=II) found that the inner bands of Aristarchus were hard to see, 
     this was odd because the seeing conditions were good and he usually 
     sees them? However he did not believe that there was any obscuration 
     going on. The Cameron 2006 catalog ID=37 and weight=0. The ALPO/BAA

     On 1983 May 28 at UT 01:50-03:00 K. Marshall (Medellin, Columbia) 
     observed the whole region of Aristarchus, Herodotus and Shroter's 
     Valley all to have a brightness of 3 and all blue and impossible to 
     focus on (he had never seen it like this before). Also the interior of 
     Aristarchus was invisible. Brightness measurement taken and a sketch 
     was made. The Cameron 2006 catalog ID=222 and the weight=3. The 
     ALPO/BAA weight=2.


2025-Oct-07 UT 23:15-01:12 Ill=99% Copernicus observed by Rawlings_G on 1978-4-23

     On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50) 
     observed a bright flash (~0.3 sec duration) near to Copernicus (20W, 
     9N) with rays to the south east whilst he looked through a finder 
     scope. Moore, who studied the drawing, suggests that the area of the 
     flash was near Copernicus. However Cameron says this cannot be the case 
     if the flash was in darkness as mentioned in the BAA Lunar Section 
     circular. She comments that it might have been a meteor? The Cameron 
     2005 catalog ID=28 and weight=1. The ALPO/BAA weight=1.

     On 1990 Jan 13 at UT 22:15-23:05 J. Pedler (Bristol, UK, seeing=III and 
     transparency=excellent, no spurious colour) detected a blue region on 
     the north of Aristarchus, varying in sharpness/diffuseness. The crater 
     rim in this region could not be descerned. Eleswhere the crater rim was 
     normal as too were other features. When a Moon blink device was used, 
     no colour blink was detected, however through the blue filter the 
     suspected area was bright and the crater rim indistinct. Whereas 
     through the red filter the area looked perfectly normal. At 22:30UT the
