     Olbers (Bremen, Germany), Browne (UK), commented that Aristarchus 
     looked like a 6-7th magnitude lumninous star, some 3-4' in diameter. At 
     19:00UT Aristarchus looked like a cloudy spot according to Ward and 
     Bailley (England, large telescope, x80). The Cameron 1978 catalog ID=
     84-85 and the weight=5. The ALPO/BAA weight=3.

     light in the centre of Mare Crisium (near a raised crevice), almost 
     like a "gigantic nuclear bomb explosion "which expanded (to 1/8th the 
     diameter of mare Crisium) and then reduced in size. The flare fickered 
     at a rate of 1/10s. apparently the edge of this TLP looked rough, 
     almost like emittyed debris. The TLP was fixed in position on the Moon. 
     TLP confirmed by observer's father. The Cameron 2006 catalog ID=295 and 
     the weight=3. the ALPO/BAA weight=2.

2018-Jun-21 UT 20:55-22:17 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

     On 1960 Aug? 01 at UT 22:00? an unknown observer detected that Vitello 
     was illuminated -it should have been in shadow? Cameron says that if

2018-Jun-23 UT 20:55-21:33 Ill=83% Plato observed by Moore_P on 1981-6-12

     P. Moore at 21:10 found the southern wall (and ontothe southern floor)
     of the crater to be indistinct. Elsewhere in the crater everything was
     sharp. The effect was still seen at 21:42UT, but less strong. A check
     was made for colour with aq Moonblink device, but none was seen. There
     was still a trace of this effect at 21:44UT, although detail was now
     becoming visible. By 21:48UT vertical streaks were seen crossing
     the floor from the obscuration area and these were more visible in the 
     red filter and not in the blue. Cameron comments that undefined patches
     on the floor of Plato are not normal. By 21:55UT some craterlets on the
     floor started to become visible and the TLP for Moore ended by UT22:23.
     P.Foley was alerted by Moore and saw a "amssive dense obsecuration
     on the south wall, south floor and south outer glacis to the Mare".
     Foley noted that by 21:50UT the effect was fading and finished by 
     22:03UT. Foley reported an orange translucent haze covering half of the 
     floor, but floor craterlets could be seen on and off - however his 
     atmospheric seeing conditions were IV. At 22:00 UT Foley reported the 
     floor close to the north wall to be "milky or misty". No detail was 
     visible at 21:15UT and variability in the floor continued until 
     23:10UT. Hedly-Robinson was aleted at 21:35UT and found no difference 
     between red and blue views of the area, however he did find that the 
     south rim was indistinct although this effect had lessened by 22:00 UT 
     and was normal by 22:17UT. M. Mobberly saw a white spot on the floor at 
     21:20 UT, whereas he normally would have expected to see craterlets. 
     Mobberly was alerted at 21:40 UT and took some colour photos. He also 
     made sketches that showed variability in the floor and dark lines and 
     patches in the north west corner. However the altitude of the Moon was 
     low. Cameron mentions that two of the photos show loss of detail at the 
     south wall and beyond.and also a change in the floor markings.The north 
     wall at 21:50UT was strangely reddish (didn't think this was spurious 
     colour). The rest of the wall was sharp at 22:20UT through a yellow 
     filter. Large bright patch in the centre and rest of the floor was 
     apparently of the same shading as Mare Imbrium. The above notes are 
     based upon the Cameron 2006 catalog extension TLP ID 145 and weight=4.
     ALPO/BAA weight=3.


2018-Jun-23 UT 21:04-00:52 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 20:55-23:17 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

     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.

2018-Jun-24 UT 20:55-22:21 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.
