2019-Aug-05 UT 06:22-06:26 Ill=23% Moon observed by Spain_D on 1988-4-21 *

     On 1988 Apr 21 at UT 01:53 D. Spain (Fairdale, KY, USA, 3.5" 
     reflector?, x60) observed a narrow white streak of mag 5-6 of duration 
     0.5 sec that covered 160-320km near the centre of the Moon at 01:53UT. 
     A similar streak happened again but the direction was different. Next 2 
     small red flashes were seen at 02:00 and 02:01UT of magnitude 7 (<1sec) 
     in the vicinity of Aristarchus. The Cameron 2006 catalog ID=327 and the 
     weight=1.


2019-Aug-11 UT 07:05-07:47 Ill=84% Plato observed by Foley_PW on 1983-7-20 *

     On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector, 
     seeing II-III) noted that the south wall of Plato at the 11 o'clock 
     position, at the location of a cleft, was fuzzy on either side of the 
     cleft. There was also a deep red colour along the cleft and the outside 
     wall. The colour had gone by 22:40 though. All other parts of the rim 
     of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III) 
     sketched some obscurations at 22:03UT. At 22:08UT the red colour 
     reduced to a red line and vanished by 22:37. The south wall obscuration 
     varied in size and there was a possible obscuration at the 7 o'clock 
     position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and 
     M.Cook's observations. Detail inside the crater was sharp, but colour 
     oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km 
     away had atmospheric ripples affecting his observations. At 21:36UT G. 
     North described the south wall as odd in appearance and the terrain 
     south of this was lacking in detail - this was odd because elsewhere 
     Plato was nice and sharp. At 21:45UT though the north section of the 
     crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5. 
     The ALPO/BAA weight=3.

     year =1887, age=8.8 days & time OK. must be same observation as ID=256 
     in Cameron 1978 catalog - note similarity of names and also the 
     reference date). Cameron 1978 catalog ID=258 and weight=1.


2019-Aug-21 UT 10:11-10:19 Ill=71% Promontorium_Heraclides observed by Doherty_EG on 1948-7-27

     Heraclides Point 1948 Jul 27 UT 02:00? Observed by Doherty (Stoke-on-
     Trent, England, 3" refractor? or 6" reflector or 10" reflector)

2019-Aug-22 UT 10:30-12:27 Ill=62% Vallis_Schroteri observed by Unknown_Observer on 1994-4-3

     On 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a 
     darkening in the Cobra Head, Schroter's valley area of Aristarchus - 
     the best example that he had ever seen. The Cameron 2006 catalog ID=474 
     and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section 
     circular 1995 Oct, p125 and personal communication from David Darling 
     to the BAA on 6/6/1995. Note it is uncertain whether this refers to the 
     Clementine mission or to somebody who observed during the Clementine 
     mission, or somebody with that surname. Anyway if it is the Clementine 
     mission then the date is wrong - possibly the year should have been 
     1994? The Cameron catalogue does actually mention a TIFF on Clementine 
     mission? The Cameron 2006 catalog ID=474 and the weight=3. I am 
     assuming that the year should be 1994 and not 1995? The ALPO/BAA 
     catalog weight=1 until we can find out what the correct date is?

     On 1996 Feb 12 at UT 07:30-08:27 J.Sandel (Caycee, SC, USA) 
     noted a contrast effect inside Tycho at sunset. At 07:30UT there 
     was a slight, but definite illumination of small areas of the 
     crater floor west of the central; peak. Also seen by T. Ferrel 
     (Lawrenceville, GA, USA, SCT C8). This was oval in shape and 
     gray in colour - Ferrel noted some diffuseness. It brightened 
     over 30 minutes. At 08:11UT a definite brightness fade noted in 
     Tycho's central peak. The crater floor had increased

2019-Aug-23 UT 12:36-13:03 Ill=51% Plato observed by Wilkins_HP on 1944-8-12

     On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52" 
     reflector) observed that central craterlet in Plato was 
     unusually bright and shows up as a bright white spot on his 
     sketch - though this might have been artistic license in his 
     sketch. His written notes refer to the unusual lack of a rim 
     (especially the northern part) to this craterlet. 
     The ALPO/BAA weight=2.

2019-Aug-26 UT 12:32-13:48 Ill=20% Earthshine: sporadic meteors

2019-Aug-27 UT 13:36-14:03 Ill=12% Plato observed by Short_J on 1751-4-22

     James Short, Dr Harris and Mr Stephens saw initially a streak of 
     light on the shadowed floor of Plato. They were not expecting to see
     any light to reach the floor. Shortly afterwards they saw a second
     streak of light parallel to the first and this shortly divided
     into two. Gaps in the mountains were found for both streaks,
     but they were unable to understand why one of the streaks divided
     into two. Cameron's 1978 assigns this TLP an ID of 20 and a weight
     of 5. The ALPO/BAA catalog assigns a weight of 1.
