2024-Jul-01 UT 00:35-00:52 Ill=27% Copernicus observed by Manchester_University on 1963-11-10

     On 1963 Nov 10/11 at UT 23:35-00:32 Kopal (Pic du Midi, France, 24" 
     refractor) observed a TLP in Copernicus. Cameron says that the date 
     maybe a misprint, should be 11/1/63? - sunset terminator at 25W and 
     Copernicus in dark. The Cameron 1978 catalog ID=782 and weight=0. The 
     ALPO/BAA weight=1.

2024-Jul-15 UT 18:55-19:30 Ill=68% Picard observed by Madej_P on 1982-10-26 *

     On 1982 Oct 26 at UT 20:41-22:22 P. Madej (Huddersfield, UK, seeing=II 
     and transparency=good) found that a blurring effect on the crater 
     Yerkes had spread to Picard (~3.5 deg brightness). The effect was not 
     detected in yellow light from the Wratten 15 filter, but a brightness 
     change was picked up in red Wratten 25 light. J.D. Cook found dark 
     surrounding Picard bright illumination. The Cameron 2006 catalog ID=188 
     and weight=5. The ALPO/BAA weight=3.

     (Yorkshire, England, Seeing II, Transparency Good) and Cook (Frimley, 
     England, Seeing=II, Transparency Good) "(Madej) could not focus Yerkes
     as well as could Peirce. By 2041 effect extended to Picard (~3.5 deg). 
     In W15 filter not apparent, but albedo change was very marked in W25 
     red filter. (M. Cook) at 2222 noted faint orange around Yerkes E. 
     Spurious color seen in other areas. Color around Yerkes intermittent. 
     In blue filter it was still orange. (J. Cook) at 2131 noted S rim
     of moon was orange & seeing was such that it was fizzing. Around Yerkes 
     only orange tint - tending intermittent" Cameron (2006) catalog ID #188

     Pico and other mountains did not show a similar effect. "It was seen 
     only in viol. filter tho once seemed blurred in red. No changes, 
     dimming was like a veil of mist covering the mtn - swiftly, then
