2018-Jun-19 UT 20:33-20:43 Ill=44% Proclus observed by Gray_R on 2003-2-8

     Proclus 2003 February 8,2003 UTC 02:09-03:07 Observed by Gray 
     (Winnemucca, NV, USA, 152mm F9 refractor Seeing 6-7, Transparency 6 
     305x) "Blinked Proclus with Wratten Red 25 and Blue 38A filters. 
     Features seen through the red filter were basically seen with the same 
     degree of clarity as in white light, in the case of sunlit walls, maybe 
     a little bit better in the red. With the Blue 38A filter only the 
     brightest part of the crater walls (north end) was visible-the rest of 
     Proclus was dark shadow. At 3:07UT I compared the brightest parts of 
     Proclus with Censorinus and Dionysius. The brightest parts of Proclus 
     and Dionysius were comparable. Censorinus was much less bright than 
     either of the above craters-the halo and crater were much faded over 
     its usual brilliant appearance. Both Censorinus and Censorinus A
     were visible as distinct craters at 114x. The black shadow covering the 
     east 40% of Proclus last night had broken up into three patches 
     separated from each other by lighter bands. These were confined to
     the east crater wall. Only the central patch was black, the other two 
     were considerably lighter. Running along the southwest edge of the 
     crater floor of the crater floor appeared to be a hill to the north
     of which was a less elevated plateau. As the observing period 
     progressed part of the brilliantly illuminated north crater wall 
     developed a darker area which gradually became more prominent. As
     the sun is getting higher I would expect shadows and dark areas to 
     diminish-what was happening here is unknown. However, this is not an 
     unusual event for this part of Proclus". The ALPO/BAA weight=2.

     On 1987 Nov 28 at UT 04:16-04:45 D. Louderback (South Bend, WI, USA, 
     3"reflector, x150, S=E) observed that the Promontorium Agarum plateau 
     was rather dull and grayish - usually it was "tannish" "even > sunlit

     plateau. At 0420 whole plateau sank into complete darkness, hard to 
     distinguish from mare plain. albedo dropped to 5 from 6.8 reading. 
     Nearby plain was normal 5 so phenomena had not spread to it. At 0424 
     Cape started to reappear to albedo 6 until 0445, when it returned to 
     normal, but not sharply defined - like through haze. Detail better in 
     red than in blue filter, sketches. The Cameron 2006 catalog ID=315 and

     On 1867 Apr 12 at UT 19:30-21:00 Elger (Liverpool? UK, 4" aperture 
     telescope) observed Aristarchus in Earthshine "grew fainter 7th mag.

     In 1878 Oct 04 at UT 20:00 an Unknown observer noted that Hyginus Nova 
     could not be seen, whereas the night before the crater had the most 
     conspicuous of all appearances. The Cameron 1978 catalog ID=201 and

2018-Jun-21 UT 20:49-21:03 Ill=65% Curtis observed by Williams_AS on 1882-9-20

     Williams of the UK, on 1892 Sep 20 at Moon's age 8.4 days, noticed a 
     spot that had been seen on the 21st and 23rd of the same year with 
     abnormal brightness. The spot was near Picard. Williams comments the 
     spot was "nearly as large but a little fainter than Picard, 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.


2018-Jun-23 UT 21:04-23:49 Ill=83% Plato observed by Brook_C on 2006-2-8 *

     C. Brook of Plymouth UK, using a 4" refractor x216, noticed at UT 20:10
     dark patches coming and going (in terms of visibility) on the floor of 
     Plato. Occasional views of the central cratelet (seen as a white spot) 
     were glimpsed. The dark patches seen lasted about 1-2 seconds before
     fading out during each visibility cycle. Teneriff Mountains were 
     checked but no sign of seeing effects that might explain the dark floor
     patches. By 20:26UT the dark patch effect was fading and by 20:31UT 
     floor detail was visible. Observations ceased at UT 20:34. Seeing 
     conditions were II and the Moon was at a high altitude. Other observers 
     were alerted but came on-line after the effect had finished. ALPO/BAA 
     weight=2.


2018-Jun-24 UT 20:33-23:17 Ill=90% Gassendi observed by Robinson_JH on 1976-10-4 *

     Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon, 
     England) - observer noted that the east outside wall was bright in red 
     and normal in blue. Note that the Moon was 30 deg above the horizon at 
     the time of the observation. The crater returned to normal at 20:58. 
     Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D. 
     Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at 
     times) noticed a possible obscuration over the southern part of 
     Gassendi. He had been observing earlier at 18:40-19:30 but had not 
     detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot 
     outside the east wall is again bright in red., though by 22:25 it had 
     faded  and was gone by 22:28UT. The Cameron 1978 catalog further 
     quotes: "Vivid red spots & general red color seen around rim by 2 obs. 
     At 2209h blood red small area was seen. 1 h later the most westerly 
     (IAU?) of the peaks had become hazy white all other areas were sharp. 
     (Indep. confirm.)." Cameron 1978 catalog weight=5 and catalog ID #1454. 
     The ALPO/BAA weight=3.


2018-Jun-24 UT 20:33-22:21 Ill=90% Aristarchus observed by Armitage_J on 2006-2-9 *

     Observer noted a bright spot on the interior west wall that seemed
     brighter than what they would have expected. unfortunately the precise
     time of this observation was not recorded so the moon-rise and 
     midnight UT values are used to place a limit on the time of 
     observation. Images by Shaw taken at UT 1754, 18:45 and 23:13
     do not exhibit the effect.

     M. Cook of Frimley, UK observed a brightening of the crater during
     this observing session. The cameron 2006 extended catalog ID=346 and 
     weight=3. ALPO/BAA weight=2.


2018-Jun-25 UT 20:33-21:07 Ill=95% Aristarchus observed by Foley_PW on 1981-4-16 *

     wall and EWBS, with a strong violet tinge on the nimbus. Crater was 
     hazy, could not focus it in red, green or blue light. The Cameron 1978
