2020-Jul-01 UT 20:22-22:08 Ill=86% Plato observed by Marshall_KP on 1982-8-1 *

     On 1982 Aug 01 at 00:00-01:00 K. Marshall (Medellin, Columbia, 12" 
     reflector, seeing I-II) noted shading on the east floor of Plato that 
     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 

2020-Jul-03 UT 20:10-22:08 Ill=98% Aristarchus observed by Moore_P on 1995-11-5 *

     Colour seen between Aristarchus and Herodotus by P. Moore
     and G. North. ALPO/BAA weight=3.

2020-Jul-06 UT 22:26-22:41 Ill=96% Aristarchus observed by Foley_PW on 1975-3-28 *

     On 1975 Mar 28 at UT22:30-23:42 P.W. Foley (Kent, UK) observed 
     orange/red in Aristarchus. The ALPO/BAA weight=1.

2020-Jul-09 UT 22:45-00:35 Ill=78% Proclus observed by Louderback_D on 1980-8-30 *

     On 1980 Aug 30? at UT 08:00? D. Louderback (South bend, WA, USA, 8" 
     refletor x140) found the north wall to be very bright in red light 
     (this is not normal as it is usually bright in blue - according to 
     Cameron). The brightness was 9.7 (red) and 9 (blue no filter)compared 
     to Eimmart's 8.7. Louderback thought that they observed an oranfe-
     yellow tinge. Cameron 2006 catalog ID=108 and weight=3.

2020-Jul-12 UT 00:55-01:23 Ill=59% Aristarchus observed by Hall on 1965-11-15

     Aristarchus 1965 Nov 15 UTC 05:55-10:00 Observed by Hall, Johnson, 
     Nordling (Pt. Tobacco, MD, USA, 16" reflector x400), Genatt (Greenbelt, 
     MD, USA, 6" refractor, x50 & 20" reflector x400), Wagmann (Pittsburgh, 
     PA, 30" refractor). "Color on c.p. detected with Trident MB, not seen 
     vis. at Port Tobacco. Network alerted & 6 responded. 4 did not see 
     anything unusual; 2 others did & saw red on c.p. in 6-in refr.. but not 
     in 20-in refl. at 400x; other saw indistinctness. Port Tobacco obs. 
     took 5 rolls of film in blue & red & neutral. Phenom. not detectable on 
     them, but focus was poor. Blue image had most detail, whereas would 
     expect red or neutral to. Phenom. still present at dawn in Moon Blink 
     device." NASA catalog weight=5. NASA catalog ID #914.
     ALPO/BAA weight=4.

2020-Jul-12 UT 00:55-01:27 Ill=59% Plato observed by Mobberley_M on 1982-8-11

     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 01:03-01:27 Ill=59% Alphonsus observed by Kozyrev on 1958-11-3

     Ezerski (Pulkova Observatory, Crimea, Ukraine, 50" reflector, 
     23A/mm spectrograph) UT03:00-03:30 "C.p. redder than rest;

2020-Jul-16 UT 01:18-01:34 Ill=22% Mare_Crisium observed by Arsyukhin on 1982-11-11

     On 1982 Nov 11 at UT 17:00-17:30 E.V. Arsyukhin (Moscow, Russia, 3" 
     reflector) saw three stationary dark spots suddenly appear in Mare 
     Crisium. There was one on the north and the other two in the south west 
     to south. They lasted approximately 30 minutes and then promptly 
     vanished. Cameron says that it cannot be this date because the Moon was 
     not visible at 17:00UT Suggests 05:00-05:30UT? The Cameron 2006 catalog 
     ID ID=189 and weight=3. The ALPO/BAA weight=2.  

2020-Jul-23 UT 19:03-19:46 Ill=12% Aristarchus observed by Cross on 1969-5-20 *

     On 1969 May 20 at UT 03:18-04:27 Cross (Las Cruces, NM, USA 6" 
     refractor), Olivarez (Spain?), Kohlenberger, Gibson, Miller, Duarte and 
     Harris (CA, USA) observed brightenings, pulsations, scintillations in 
     Aristarchus crater. Cameron says independent confirmation seen by 4 
     observers, 1-2 magnitude increases, ranged between 1-30sec. Most active 
     period was 03:18-03:20UT, 04:17-04:27UT (Las Cruces). Calkins (West 
     Covins, CA, USA) UT 03:40-04:25 saw one major brightening up 2 
     magnitudes above steady state lasting 0.2 to 1.5 sec and another slow 
     brightening lasting 5-10 seconds. Kelsey (CA, USA) saw at 03:43-03:48UT 
     some brightenings. These observations were made during the Apollo 10 
     watch. The Cameron 1978 catalog ID=1127 and 1128 and weight=5. The 
     ALPO/BAA weight=4.
