2020-Jul-01 UT 02:36-02:39 Ill=80% Sinus_Iridum observed by Manske_R on 1987-10-3

     On 1987 Oct 03 at UT 01:0?0-02:00 R. Manske (Brooklyn, WI, USA, 8" 
     reflector, x226) observed sunlight glinting of the walls in spectacular 
     display of colours. White (even gold) was seen at the centre, and blue 
     on the top most part of the rim. The white (or gold) band was thin in 
     comparison to other bands. The observer suspects that this effect was 
     terrestrial atmosphere related. Cameron 2006 catalog ID=307 and weight=
     0. ALPO/BAA weight=1. 


2020-Jul-01 UT 02:43-03:11 Ill=80% Plato observed by Beaumont_S on 1998-3-8

     Plato 1998 Mar 08 UT 19:30-20:10 S. Beaumont (Windermere, UK, 
     30cm reflector, Meade 23A and 38A filters, seeing III, 
     transparency fairly good, some haze) observed a whitish misty 
     effect seen bordering the shadows of the SE rim. It appeared 
     intermittently and was not seen in the violet or red filters. 
     Observers wonders if it could have been an effect associated 
     with the Earth's atmosphere, which was unsteady with some haze. 
     However, other craters appeared normal. The ALPO/BAA weight=1.


2020-Jul-02 UT 02:39-04:33 Ill=89% Aristarchus observed by Zeller_P on 2013-4-22

     On 2013 Apr 22 UT 01:39-02:37 P. Zeller (Indianapollis, USA, 
     10" f/4 reflector, x200, seeing 6, Transparency 3 - scattered 
     cirrus) observed visually (depicted in sketch) the two closely 
     spaced NW wall dark bands) to have a rusty-red hue. The colour 
     of these bands did not change over the period of the observing 
     session. Images were taken, but resolution and image S/N is 
     not sufficient to resolve separate bands here, or to detect 
     colour. The ALPO/BAA weight=2.

     UK, 15" reflector x250 S=IV) and Argent and Brumder (Sussex, 
     UK). In early sunrise conditions, W. wall was less brilliant 
     than usual -- matched only by Sharp, Bianchini, & Marian. 
     Extraordinary detail could be seen on this wall. Also noted 
     intense & distinctly blue color entire length of W. wall. 3 
     others corroborated detail, but not color. Moore found things 
     normal & saw Aris. brightest at 2030-2125h tho Argent & 
     Brumder made it < Proclus" NASA catalog weight=4. NASA catlog 
     ID #1422. ALPO/BAA weight=1.


2020-Jul-02 UT 03:45-05:36 Ill=89% Plato observed by North_G on 1981-8-11

     On 1981 Aug 11 at UT21:05-21:36 G. North (England, seeing=poor) 
     detected, in green light, a darkening on the floor of Plato. This 
     effect was not seen elsewhere. J-H Robinson (Teighmouth, Devon, UK) 
     detected on the SSE rim (inner and beyond) a triangle that appeared 
     hazy in a wide range of filters at 21:05UT. However at 21:36UT it was 
     only hazy in green and blue light. No similar effect was seen 
     elsewhere. The Cameron 2006 catalog ID=150 and weight=5. The ALPO/BAA 
     weight=3.


2020-Jul-02 UT 04:35-05:45 Ill=89% Gassendi observed by Cook_AC on 1977-10-23

     On 1978 Oct 23 observing period: UT22:00-22:40 A.C. Cook (Frimley, 
     Surrey, UK, 6" reflector, x144, 6mm Ortho eyepiece, seeing IV, red and 
     blue filters used) saw at 22:10 a secctor on thwe western floor to be 
     mainly bright in the red. The surface was bumpy here. The observer at 
     the time commented that this was probably not a TLP, but no precise 
     explanation given. ALPO/BAA weight=1.

2020-Jul-02 UT 05:34-05:45 Ill=89% Herodotus observed by Martini_A on 2017-2-8

     On 2017 Feb 08 UT 01:45 A.Martini Jr (10" Schmidt-Cassegrain 
     with ASI 120 MC camera +IR filter, Gain 40, Gamma 36, 
     exposure 0.003 sec) saw on a computer monitor screen a flash 
     to far to the west of Herodotus and Aristarchus at the 
     location 54.53W, 23.5N. It had a duration of 0.5 sec and on a 
     brightness scale of 0 = night side of the Moon to 10 = 
     Aristarchus, ranked 7. Unfortunately they were not recording 
     at the time. As there was no confirmation observation and it 
     could be a cosmic ray air shower detection, the ALPO/BAA 
     weight=1

     On 1979 Sep 09 at UT08:00-08:15 D. Darling (Sun Praire, WI, USA, 12.5" 
     reflector, x75 and photography used, seeing 4/10 and the Moon's 
     altitude was 45deg) photographed Romer crater and recorded two adjacent 
     bright cigar shaped objects - these were the same size as an 
     observation made in 1987. Darling believes that these are ridges. 
     Cameron comments that in LO-IV 192-3,2 a ridge is revealed on the 
     inside wall that matches the description. Cameron 2006 catalog ID=66 
     and weight=2. ALPO/BAA weight=1.

     On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"? 
     reflector, seeing III) found that Aristarchus was very bright 
     and slightly blue. Cameron comments that Moore's eyesight is not 
     very blue sensitive. The Cameron 2006 catalog ID=175 and weight=
     4. The ALPO/BAA weight=2.

     Moon, and that there was colour detected with a Moon blink device on 
     the floor of Grimaldi. The Cameron 2006 catalog ID=175 and the weight=
     4. The ALPO/BAA weight=3.


2020-Jul-10 UT 10:14-11:05 Ill=74% Aristarchus observed by Bartlett on 1964-7-29

     1964 Jul 29 UT 05:40-06:06 Observed by Bartlett (Baltimore, MD, 
     USA) "Nimbus only -- dark viol. hue. S.floor granulated, dull -- 
     6 bright. Faint yellow-brown tinge. Rest of crater 8." S=6, T=3-

2020-Jul-12 UT 09:20-10:18 Ill=56% 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?


2020-Jul-12 UT 09:49-11:07 Ill=55% Aristarchus observed by Bartlett on 1964-7-31

     Aristarchus 1964 Jul 31 UT 02:00-02:23 Observed by Bartlett 
     (Baltimore, MD, USA, 5" reflector x180) "Deep ravine on E.glacis 
     interrupted midway of its length by apparent break just below

2020-Jul-13 UT 10:10-11:08 Ill=46% 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.


2020-Jul-13 UT 08:38-10:26 Ill=46% Earthshine: sporadic meteors

2020-Jul-14 UT 08:59-10:27 Ill=36% Earthshine: sporadic meteors

2020-Jul-15 UT 09:23-10:29 Ill=27% Moon observed by Darling_D on 1979-9-16

     On 1979 Sep 16 at UT 08:00-09:00 D. Darling (Sun Praire, WI, USA, 
     12.5" reflector, x62-x97, clear, but Moon at low altitude) detected 
     four new features that he had not seen before in Earthsine in 
     comparison with what he saw on 16 Jul 1979, this time in the southern 
     part of the Moon. pin-point flashes were seen within these bluish 
     areas. Each time a flash occurred the gas clouds brightened (sometimes 
     by 6x) for a few seconds. Cameron thinks that these are related to 
     moving clouds on the Earth's limb e.g. mackeral sky. Cameron 2006 
     catalog ID=69 and weight=1. ALPO/BAA weight=1.


2020-Jul-15 UT 10:14-10:47 Ill=27% Briggs_A observed by Butler_FC on 1980-2-11

     Briggs A 1980 Feb 11 UT 06:30-07:00 Observed bt Butler_FC 
     (Brixton, UK, 22cm Newtonian reflector, x64, x104, seeing IV). 
     Found Briggs A to be brownish in colour at x64, however the 
     colour vanished at 06:55 when x104 was used. Switching back to 
     x64 the colour was still there but fainter. The colour fade may 
     have been due to day light glare encroaching? Could not see this 
     effect anywhere else on the Moon but did detect what he regarded 
     as a permanent coloured spot (yellow) between Cruger and 
     Grimaldi. ALPO/BAA weight=1.


2020-Jul-15 UT 09:23-10:28 Ill=27% Earthshine: sporadic meteors

2020-Jul-17 UT 10:30-10:36 Ill=12% Dawes observed by Hewick_G on 1997-10-28

     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).


2020-Jul-17 UT 10:36-11:12 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.


2020-Jul-24 UT 02:21-02:31 Ill=14% W_Limb observed by Hopkins_BJ on 1883-3-12

     reflector, x62) found the crater to blow and fluctuate between 
     magnitude approximately 4 and 5. Initially it was bright, then faded, 
     then brightened again aggroximately x2 and then faded into the 
     background. The Cameron 2006 catalog ID=70 and weight=0. The ALPO/BAA

     seeing II, Transparency poor). A very bright point located at 
     23N 54.5E this was normal! - what was unusual was that it 
     vanished when viewed through a blue Wratten 38A filter (this 
     filter absorbs red, UV, and some green light). The ALPO/BAA 
     weight=2.

     21.5cm Newtonian, seeing Antoniadi I/II, Transparency very 
     good) was observing in earthine and saw an intense blue spot 
     "wink on" near to Sirsalis (sketch shows location on SE rim), 
     until clouded out at 18:30. When the sky cleared at 19:15UT 
     the spot was still visible but fainter, with a halo, the size

2020-Jul-26 UT 02:18-03:16 Ill=34% Gassendi observed by Williamson_P on 1990-3-2

     On 1990 Mar 02 at UT 19:35-19:50 P. Williamson (Shropshire, UK, 14" 
     reflector, x178, seeing=good and steady) noticed a yellow-orange glow 
     in Gassendi (from a small illumnated crater?) in Earthshine at 19:35UT 
     and by 19:40UT it had become very bright white, afterwhich it 
     completely faded within 10 minutes. The Cameron 2006 catalog ID=393 and 
     the weight=1. The ALPO/BAA weight=3.


2020-Jul-26 UT 02:23-03:16 Ill=34% Daniell observed by Price_M on 1979-12-24

     M. Price of Camberley, UK noticed that an area in relation
     to the central area of the floor could not be resolved. Averted
     vision was used, but this did not help to resolve detail. The crater
     was close to the terminator and was in general sharply in focus
     apart from the suspect area. No spurious colour seen. Sketch
     supplied.P. Foley wonders if the effect was due to the resolution
     limit of Price's scope? Cameron 2006 extension catalog ID=78
     and weight=2. ALPO/BAA weight=2. 6" reflector x64 and x120.
     Seeing=III-IV and Transparency=good.


2020-Jul-26 UT 03:01-03:16 Ill=34% Aristarchus observed by McIntosh on 1969-7-20

     On 1969 Jul 20 at UT 0845 McIntosh (Auckland, New Zealand, 14" 
     reflector) saw Aristarchus crater to be brighter in red light. This was 
     during the Apollo 11 watch. The Cameron 1978 catalog ID=1173 and 
     weight=3. The ALPO/BAA weight=3.

2020-Jul-27 UT 02:17-02:46 Ill=45% Censorinus observed by Cook_AC on 1985-6-24

     On 1985 Jun 14 UT 21:16-21:40 Observed by A.C. Cook Frimley, UK, 
     30cm reflector, seeing IV, transparency moderate, very litle 
     spectral dispersion noticed - Wratter 25 and 44a filters used) 
     UT 21:16-21:19 Censorinus slightly brighter in red and more 
     detail seen. Observed other features before and after this. 
     Checked again UT21:31-21:40 - same appearance. Torricelli and 
     Torricelli B in comparison looked normal with other craters of 
     similar size. ALPO/BAA weight=1.


2020-Jul-27 UT 02:30-03:33 Ill=45% Proclus observed by Unknown_Observer on 1988-7-21

     On 1988 Jul 21 at UT 01:00? an Unknown observer (name and geographical 
     position not given in the cameron catalog) detected a darkening on the 
     floor of Proclus crater - this was also seen by other observers - some 
     of whom were making observations independently. The Cameron 2006 
     catalog ID=330 and the weight=1.

2020-Jul-28 UT 02:16-02:23 Ill=57% Alphonsus observed by Poppendiek on 1958-11-19

     Large plume-like diffuse cloud over central peak, very
     large compared to central peak (@ approx 30km diameter)
     with intensity much different from other parts. Brightness
     between walls and shadowed floor. Would take 3 minutes to
     collapse, so continuously fed. 13-14 days later, at SS,
     central peak was normal. Kuiper took photos after Kozyrev's
     observations, but saw nothing abnormal. Drawing. Haas saw
     nothing in 12inch reflector at the time. Cameron 1978
     catalog TLP ID=705 and weight=4. ALPO/BAA weight=2.


2020-Jul-28 UT 02:16-03:36 Ill=57% Alphonsus observed by Harris on 1966-6-26 *

     Alphonsus 1966 Jun 26 UT 04:30-04:40 Observed visually by 
     D.Harris and E.Arriola (Whittier, CA, USA, 19" reflector x146, 
     and spectrum, S=4, T=1-0) "Absorp. spectrum (visual) of c.p. 
     band at 475+/-5nm (1st est.); 2nd est. at 485+/-5nm. Band 
     degraded towards the viol. Band nr.Hydrogen Beta. as if 
     abnormally broadened. So sign of anything unusual visually in 
     central peak in white light. Absorption appeared only on C.P., 
     not over walls. Calibration corrections put band at 491+/-4nm" 
     NASA catalog weight=5. NASA catalog ID #948. ALPO/BAA weight=5.


2020-Jul-28 UT 02:59-03:46 Ill=57% Proclus observed by Foley_PW on 1988-7-22

     On 1988 Jul 22 at UT 02:15-04:00 P.W. Foley (Kent, UK, 11" 
     reflector) made a sketch of a dark area of the (East) floor of 
     Proclus that revealed a large anomalous dark region - there 
     should be no shade here when the sun is at an altitude of above 
     50 deg!. BAA lunar section archives reveal similar dark shadings 
     - however on this night it was a different shaped dark area. The 
     appearance was confirmed by several observers. Foley reported 
     that the region affected stretched from Proclus to Theophilus. 
     The TLP was seen in the USA too by D, Darling as early as 
     01:31UT and by others on his TLP network - brightness 
     measurements of the "c.p." were 3.5 and the remainder of the 
     floor was 5.5. However the observers did not all agree on the 
     same position for this dark area. The Cameron 2006 catalog ID=
     331 and the weight=2. The ALPO/BAA weight=2.

2020-Jul-29 UT 02:33-03:14 Ill=68% Alphonsus observed by Wilkins_HP on 1958-12-19

     Alphonsus 1958 Dec 19 UTC 20:00? Observed by Wilkins (Kent, England) 
     decsribed in the NASA catalog as: "Reddish patch on central peak" 15" 
     reflector used. NASA catalog weight=4 (high). NASA catalof TLP ID No. 
     711.


2020-Jul-29 UT 02:39-03:55 Ill=68% Atlas observed by Knopp_R on 1994-4-19

     On 1994 Apr 19 at UT 22:00 R. Knopp (Berlin, Germany) noticed a 
     darkening of the interior of the crater Atlas. The ALPO/BAA weight=1. 


2020-Jul-30 UT 02:14-03:54 Ill=78% Plato observed by Mobberley_M on 1986-5-18

     On 1986 May 18 at UT 20:45-22:25 M. Mobberley (Suffolk, UK, seeing II-
     IV) found that the central craterlet of Plato was an Žasily seen "white 
     splodge" although it was quite difficult to see when imaged with video. 
     Foley and Cameron comment on IR sensitivity of the CCD camera used. The 
     Cameron 2006 catalog ID=285 and the weight=1. The ALPO/BAA weight=1. 


2020-Jul-30 UT 02:14-02:55 Ill=78% Plato observed by Albert_J on 2009-4-5

     On 2009 Apr 05 at UT 01:03-01:31, 01:44 and 02:30 J. Albert 
     (FL, USA, 11"  reflector, x224 and x311, transparency 4-3 
     and seeing 5-6/10) noted a tiny point on the south east
     rim of Plato, adjacent to the east wall shadow. It was
     first seen at x311 without filters, then in both Wratten
     25 (red) and Wratten 38A (blue) - it was faintest in the
     latter. The spot was probably a high point on the south east
     rim. By 01:28UT the spot was no longer visible in the blue
     filter, but could still be seen well in red and white light.
     No change was seen during rechecks at 01:44 or 02:30. The
     observer considers that this was not a TLP as it was on the
     limits of detectability and anyway observing conditions were
     poor. The ALPO/BAA weight=1. 


2020-Jul-30 UT 03:26-03:56 Ill=78% Proclus observed by Darling_D on 1988-7-24

     On 1988 Jul 24 D. Darling (Sun Praire, WI, USA, 12" reflector, 
     x150, S=7/10, T=3) observed the following in Proclus: "At 0213 
     the previously observed gray area was 1/3 of July 22 and V 
     shaped and fanned out across the floor. Could see hint of knot 
     seen before. Craters named in 7/23/88 (#319) were all normal 
     this time too". Is it possible that this report refers to the 
     crater "Gray" rather than "Proclus" as the column field suggests 
     in the Cameron catalog? The Cameron 1978 catalog ID=333 and 
     weight=5. The ALPO/BAA catalog weight=2.


2020-Jul-30 UT 03:31-03:56 Ill=78% Plato observed by Madej_P on 1981-9-8

     On 1981 Sep 08 at UT 21:28-21:34 P. Madej (Huddersfield, UK, seeing 
     III-IV and trasnaparency good) observed a light orange transparent 
     cloud extending from the north east inner corner across over the floor 
     of Plato. Camero comments that this report was confirmed by 3 othr 
     observers. The shape of this clud varied. The Cameron 2006 catalog ID=
     153 and weight=4. The ALPO/BAA weight=3.
