     12.5" reflector, 80x and 150x, S=5/10). A weak blue glow seen in the 
     Aristarchus region. It was fainter than that in May 1979 but was 
     relatively easier to see. There was one "streamer" going south and 
     another to the south west, and then smaller ones within the crater. 
     These streamers started to fade from view at 03:04UT and the blow glow 
     changed to a blow spot and Aristarchus became normal by 03:19 UT.

     Observer: Fallows Observing site: Cape Town, South Africa. Cameron 1978 
     catalog describes the event as: Bright star-like point.
     A more detailed account is as follows: Early in the year 1821 -- and a 
     light shone out on the moon -- a bright point of light in the lunar 
     crater Aristarchus, which was in the dark at the time. It was seen, 
     upon the 4th and the 7th of February, by Capt. Kater (An. Reg., 1821-
     689); and upon the 5th by Dr. Olbers (Mems. R.A.S., 1-159).(25) It was 
     a light like a star, and was seen again, May 4th and 6th, by the Rev. 
     M. Ward and by Francis Bailey (Mems. R.A.S., 1-159).(26) At Cape Town, 
     nights of Nov. 28th and 29th, 1821, again a star-like light was seen 
     upon the moon (Phil. Trans., 112-237).(27).Cameron 1978 catalog ID=92

     On 1988 Nov 15 at 10:07-10:40 UT P. Jean (Outremont, Quebec, Canada, 
     4" refractor?) saw to the SE of Eudocus (18E, ~43N) a luminescent area 
     just over on the night side of the terminator - it was cone shapes and 
     coppery in colour. Cameron comments that maybe it was a very low sun 
     angle effect and she has seen something similar, but on the bright side 
     of the terminator. Jean then goes onto comment that at 10:25UT a very 
     dark line was seen south of the cone i.e. east of the terminator. A 
     sketch was provided and P.Foley commented that the cone did not 
     correspond to any terrain. Cameron 2006 Catalog Extension ID=339 and

     a minute. ALPO/BAA weight=1.


2019-Apr-11 UT 05:36-07:32 Ill=33% 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.

     was taking place on Mount Piton. The mountain peak looked like a 
     shimmering block of ice with a phosphorescence luminescence cloud 
     around the peak. What was really interesting was the shaft of light 
     streaming across the Lunar Maria that appeared like a cone and it came 
     to a point near Mount Piton. The Mountain had the appearance of mother

2019-Apr-12 UT 06:00-09:38 Ill=45% Earthshine: sporadic meteors

2019-Apr-12 UT 10:36-11:56 Ill=46% Mons_Piton observed by Horne_P on 1983-3-21 *

     On 1983 Mar 21 at UT 21:05-22:00 P. Horne and J. Horne (Hertz, England, 
     UK, 11" reflector, x180 and x330) found that Mons Piton (totally 
     illuminated and brightest feature on the Moon - but no variability) was 
     brighter than Aristarchus (would have been if it had been in sunlight)
     and the mountain was contained within a circular illuminated patch. 
     "Brilliant white and no shadow. Size ~16km." There was no details 
     visible but the adjacent features had distinct shadows. Hutton was also 
     observing. Foley examined the photographs and believes that they are 
     inconclusive. D. Mansbridge was photographing the Moon at 19:30UT and 
     detects Piton but it is not bright. However in a photograph taken by D. 
     Mansbrdige and 20:30UT the mountain is much brighter than any other 
     sunward facing slopses on the northern part of the Moon's terminator. 
     R. Mosley had been observing earlier at 18:10-19:40 and although

2019-Apr-13 UT 06:55-08:35 Ill=56% 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.

2019-Apr-14 UT 05:10-06:32 Ill=66% Mons_La_Hire observed by Geisel_M on 1972-11-15

     Mons la Hire 1972 Nov 15 UT 09:45-10:18 M.Geisel (Brisbane, 
     Australia, 12.5" f/8 reflector, x90) discovered the TLP, P. 
     Anderson (9.5" reflector) independently confirmed that the TLP
     had an effect in his Moon Blink device - but the effect 
     (suspected that the blink was caused by the extreme nrightness 
     of the mountain?) was weak and thought it not worth further 
     investigation. Photographs taken by Anderson. Geisel believes 
     the effect to be real and states that the area remained sharp 
     and clear throughout. ALPO/BAA weight=2.


2019-Apr-14 UT 05:10-05:53 Ill=66% Aristarchus observed by Foley_PW on 1980-5-23

     On 1980 May 23 at UT22:30 (P.W. Foley (Kent, UK, 10" reflector, seeing 
     II) described Aristarchus as a "blue luminous patch", but it was too 
     faint to obtain a CED brightness measurement. Cameron 2006 catalog ID=
     96 and weight=3. ALPO/BAA weight=2.


2019-Apr-14 UT 05:10-05:41 Ill=66% Tycho observed by Blair_G on 1980-5-23

     On 1980 May 25 at UT 22:18 G. Blair (Bridge of Weir, Scotland, 216mm 
     reflector, seeing II-IV) suspected a short sharp flash, white in colour 
     north of Tycho's north wall. Nothing more seen. ALPO/BAA weight=1. 


2019-Apr-14 UT 05:10-05:43 Ill=66% Copernicus observed by Horner_E on 2012-9-24

     2012 Sep 24 UT 22:00-23:00 Copernicus. E. Horner (Salisbury, 
     UK, 15cm reflector) observed a prominent red arc where the 
     sunlit part of the interior wall met the shadow. Sometimes the 
     arc was 1/4 the way around the interior, and sometimes half of 
     the way around. Telescope moved, but the red arc stayed where 
     it was. Eyepieces change, but the effect remained. Other parts 
     of the Moon checked, but no red seen. There were however 
     splashes of green e.g. Longomontanus on the terminator, 
     elsewhere further inland from the termionator, and little 
     splashes of green on Mare Frigoras - but lasting a brief time. 
     The red colour was as strong as a red LED and the green similar 
     to that of the northern lights. The observer's husband was asked 
     to independetly check Copernicus and remarked that he could see 
     a little bit of green at the top and some red near the bottom, 
     along the line of the internal shadow. Although there were 
     checks for red elsewhere on the Moon and none were seen, the 
     Moon was starting to get low and it is typical of spurious 
     colour in a few respects. Therefore the ALPO/BAA weight=1 for 
     safety.

2019-Apr-15 UT 05:13-06:51 Ill=77% Copernicus observed by Johnstone_GH on 1954-11-6

     Observed by G.H. Johnstone of Albuquerque, NM, USA on 1954 Nov 05 UT 
     20:00 (according to Cameron), but 02:00-04:00 according to the
     original observation and at colongitudes 34.7 to 35.7 deg. 4" 
     reflector, x150 used. The obsewrver reported that the western part 
     (about 1/3rd of the interior) was pitch black with shadow. However 
     there was a zone about as wide, or perhaps only a fourth of the total 
     width that was distinctly a lighter bluish shade, almost like twilight. 
     The shadows of the peaks on the western edge of the rim were clearly 
     seen crossing this bluish shadowed area. Then this area ended sharply, 
     and the farside was bathed in light from the rising sun. The shadows of
     the peak were sharply defined across the twilight zone, and the edge of 
     the pitch black shadow was easily defined but not as sharp as the
     darker shadows crossing the the blue twilight zone. The observer 
     checked other craters but did not see this condition in any of them - 
     they all had the abrupt division between black and white that we would
     normally expect to see. Cameron 1978 catalog ID=579 and weight=2.

2019-Apr-15 UT 06:49-07:00 Ill=77% 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.

2019-Apr-15 UT 08:42-09:50 Ill=78% 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.


2019-Apr-15 UT 09:34-11:07 Ill=78% Censorinus observed by North_G on 2007-10-21

     At approximately 18:43UT observer noticed that Censorinus, and 
     its bright apron, appeared particularly brighter than normal. 
     There was some spurious colour present - but just a redness 
     along the southernmost extent of the apron visible; could not
     detect any blue along the northern edge however, he did do not
     suspect the colour to be anomalous. A re-examination at 18:51UT 
     revealed that the crater had faded and was seen to fade visibly 
     in real time to normal levels (over about a minute) by 18:53UT. 
     Other features remained constant and so too did the apparent 
     spurious colour.

2019-Apr-16 UT 06:17-07:19 Ill=86% 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.

     20cm reflector, x64, x128, Seeing IV, Transparency, moderate) 
     "Torricelli B appeared rather dull with a prominent dark halo of a 
     strongly bluish tint. The halo extends a few sec of arc beyond the 
     crater. At 21:21-21:43 crater was varying in brightness but this may 
     have been due to the seeing? By 21:42 the dark halo was gone. By 21:44-
     21:49 UT the crater was brighter and more normal in brightness than 
     before. By 22:17 UT all was normal. The variations in brightness were 
     also seen by Cook (Mundesley, UK). Observations by Carbognani (Itlay) 
     21:20-23:10 failed to find any variations in brightness. Nor did Amato 
     (CT, USA) from 23:00-23:15 UT."

     that initially that the crater was pretty dull and that the floor
     was a slate blue-gray in colour at 22:45UT. A noticeable green spot
     inside the crater on the south east appeared at 22:25UT and vanished

     lights were seen by Pratt, and 28 by Elger, but only 4 by Gledhill, in 
     Brighton. Atmospheric conditions may have made this difference, or the 
     lights may have run up and down a scale from 4 to 28. As to 
     independence of sunlight, Pratt says (Rept. B.A., 1871-88), at to this 
     display, that only the fixed, charted points so shone, and that other 
     parts of the crater were not illuminated, as they would have been to an 
     incidence common throughout.(30) In Pratt's opinion, and, I think, in 
     the opinion of the other observers, these lights were volcanic."

     opposite to the crater interior bands. Cameron states that 
     Foley says that this is usual. High CED brightness readings 
     obtained. M.Cook of Frimley, UK, took CED measurements at
