2019-Aug-04 UT 03:44-03:48 Ill=13% Aristarchus observed by Albert on 1965-7-2 *

     In 1965 Jul 02 at UT 04:20-05:50 Albert and Welch (Azuss, CA, USA, 8" 
     reflector, x375) and Emanuel  (West Covina, CA, USA, 4.5" reflector) 
     observed 4th magnitude star-like flashes to blotches in Aristarchus, in 
     ashen light. Cameron says that this is independent confirmation and 
     also that the date in MBMW is 7/1/65 which is local time + 2nd UT. The 
     Cameron 1978 catalog ID=881 and weight=3. The ALPO/BAA weight=3.


2019-Aug-05 UT 03:43-03:53 Ill=22% N_Pole observed by Chernov_VM on 1978-3-13

     On 1978 Mar 13 at 17:25UT V.M. Chernov (Soviet Union) observed that the 
     northern cusp was elongated into Earthshine, 4.6 days after New Moon. 
     One day before this the cusps appeared nromal to him. The ALPO/BAA 
     weight=1.


2019-Aug-05 UT 03:43-05:29 Ill=22% Aristarchus observed by Fryback_D on 1988-4-21 *

     On 1988 Apr 21 at UT 01:28-04:00 D. Fryback (Madison, WI, USA) took a 
     series of photographs - Aristarchus was a luminous patch and in one 
     photograph a red spot (Cameron suspects marks on the film). is seen 
     near Aristarchus. Strangely though when looking through the telescope, 
     the crater was not excessively bright. 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 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-05 UT 03:43-05:29 Ill=22% Moon observed by Spain_D on 1988-4-21 *

     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.

     On 1985 May 24 at UT 21:01-22:40 P.W. Foley (Kent, UK, 12" reflector) 
     observed that Aristarchus was very bright (varied) and had a strong 
     (transient) red/rose colour and the crater floor was glowing. Detail 
     was visible. Mobberley (Suffolk, UK) also found the floor of the crater 
     to be "glowing". Photographs of Earthshine excellent. The Cameron 2006 
     catalog ID=274 and the weight=5. The ALPO/BAA weight=3.

     On 1871 Nov 20 at UT 17:30-19:30 H. Pratt (UK) saw one of the most 
     spectacular TLP obscurations that he had ever seen in Mare Frigoras. He 
     observed a kind of haze around the north west (NE?) slopes of Plato. 
     This effect was not seen elsewhere and all objects in Mare Frigoris 
     were indistinct or veiled. By 18:30 the effect was modified and by 
     19:30 very little trace was seen. Ref. from Corliss.

     12.5" reflector x450) "Noted a bright area in the center. Moore 
     noted nothing unusual & he tho't obs. saw one of permanent light 
     patches" NASA catalog weight=0 (very low). NASA catalog ID #
     1336. ALPO/BAA weight=1


2019-Aug-09 UT 03:57-04:35 Ill=65% Plato observed by Elger_TG on 1887-2-1

     Plato 1887 Feb 01 UT 18:00 Observed by Elger (England) "Ill-defined 
     shadow of peaks of W.border-in contrast to sharpness of mts. outside 
     it. Never seen before. Such phenomena occur on floor, but never on 
     ramparts. (Drawing)." NASA catalog weight=4 (high). NASA catalog 
     ID #254. ALPO/BAA catalog weight=1.


2019-Aug-11 UT 07:05-08:23 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.

     On 1979 Nov 09 at 10:30-11:05UT D. Louderback (South Bend, WA, USA, S=
     4-2/10, T=P) detected a rapid fade in brightness of south and north 
     sunlit slopes of Mons Piton. Then the western flank faded and became 
     obscured in detail. The variations detected were approximately 5 sec in 
     duration, where as seeing effects were of the order of 15 sec. Mons 
     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,

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?

     (Parnaiba, PI, Brazil, 9.5" reflector, x90, seeing=good) 
     observed during a lunar eclipse that the Straight Wall 
     surroundings were darker than an observation from two days 
     earlier. At 07:09UT tonality became clearer. As dawn was in 
     progress and atmospheric turbulence, not sure if it was a TLP? 
     Other features were normal. The Cameron 1978 catalog ID=1297 and 
     weight=1. The ALPO/BAA weight=1.


2019-Aug-23 UT 11:01-12:50 Ill=52% Tycho observed by Sandel_J on 1996-2-12

     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

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.

     On 1987 Oct 28 at UT 05:05 G. Hewick (UK) observed a 1 sec duration 
     flash on the lunar surface (night side) whilst waiting to observe a 
     lunar occultation of X17959. The colour was yellow and the brightness 
     was approximately magnitude 1 - there was no movement. The location of 
     the flare was between Daws and Vitruvius (17N, 29E).


2019-Aug-27 UT 12:11-13:26 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.
