2018-Apr-01 UT 00:03-00:34 Ill=99% Aristarchus observed by Theiss on 1973-8-13

     Aristarchus 1973 Feb 15 UTC 17:07-19:31 Observed by Theiss (located at 
     51N 5.67E) "area 4-5 diameters of Aristarchus were coloured clearly 
     yellow-red" 120mm reflector used. Ref Hilbrecht & Kuveler (1984) Moon 
     and Planets Vol 30 p53-61. ALPO/BAA weight=1.


2018-Apr-01 UT 00:03-01:41 Ill=99% Plato observed by Livesey_R on 1973-8-13

     Plato 1973 Aug 13 UT 22:25-22:35 observed by Pedler (Devon, UK). 
     Observer noticed a slight blink on a lighter patch on the floor 
     just beneath the south(?) rim using Moon blink filters. 
     ALPO/BAA weight=1.


2018-Apr-01 UT 01:35-03:32 Ill=99% Aristarchus observed by Darling_D on 1989-10-15

     David Darling observed bright glittering on Aristarchus. This
     was followed by a flare up in brightness at 00:38:05 UT in the
     comet-like ray area of the crater equivalent in intensity to the
     central peak. Then he saw another one on the north east rim of 
     Aristarchus of the same brightness. A third flare was seen at
     00:49UT in south of Herodotus, on the comet-like ray. Another
     two flares were observed at 00:56UT on the north west rim of
     Aristarchus. Darling suspects that these effects were due
     to seeing effects and Cameron agrees. However Weier suspects
     that they were TLP? Brightness measurements by Weier were for
     the south west rim of Herodotus 8.0, for a spot at the Cobra's
     Head 9.0 and 7.5 for C.H. Cameron apparently did not see the flashes
     but did suspect that the interior of Aristarchus was a bit unusual. 
     Don Spain did not see anything unsual at all. Cameron 2006 extended
     catalog ID=380 and the observation weight=3. The ALPO/BAA weight=2. 


2018-Apr-01 UT 02:05-04:02 Ill=99% Herodotus observed by Kilburn_K on 1971-12-2

     (Manchester, UK, 8" refractor, x130, Transparency very good 
     with a thin mist, seeing excellent, x130). Bright point 
     (considerably brighter than its surroundings) was seen on the 
     SE of the illuminated floor of Herodotus in white light. It 
     was quite close to the crater rim. The spot had no colour. 
     ALPO/BAA weight=2.

     England, 8" reflector) "Crater took on an unusual appearance on inner 
     NE (ast. ?) wall. Showed a very pale blue & the opposite wall a pale 
     red color seen in no other features. Lasted only 10m & survived a

2018-Apr-01 UT 02:46-04:37 Ill=99% Aristarchus observed by Brook_C on 2002-3-29

     On 2002 mar 29 at 02:20-02:38UT C. Brook (Plymouth, UK, 60mm refractor, 
     x120 - no cloud, slight haze, no wind, seeing good) noticed during 
     first part of observing period that Aristarchus was getting steadily 
     brighter, very much brighter than Proclus. This continued until 02:36UT 
     when it dimmed suddenly over a period of about a minute or so. No 
     colour effects seen. ALPO/BAA weight=2.


2018-Apr-01 UT 02:46-04:37 Ill=99% Proclus observed by Brook_C on 2002-3-29

     On 2002 mar 29 at 02:20-02:38UT C. Brook (Plymouth, UK, 60mm refractor, 
     x120 - no cloud, slight haze, no wind, seeing good) noticed during 
     first part of observing period that Aristarchus was getting steadily 
     brighter, very much brighter than Proclus. This continued until 02:36UT 
     when it dimmed suddenly over a period of about a minute or so. No 
     colour effects seen. ALPO/BAA weight=2. Just as an after thought - was 
     it Aristarchus that was varying, or Proclus?


2018-Apr-01 UT 03:09-05:00 Ill=99% Eimmart observed by Louderback_D on 1980-4-30

     Louderback, of South Bend, WA, USA observed a bright area over
     Mons Anguis and Eimmart - it resembled a comet and had a bluish 
     colour and varied in brightness. The colour was confirmed as it 
     was not seen in a red filter but could be seen in blue and white 
     light. Other features were checked but did not show anything 
     similar although a violet glare was suspected in the blue filter. A
     sketch was made. Observer made Eimmart 8 in brightness at 07:30UT.
     Noted that the area around Eimmart appeared opaque at times and less so
     at other times. At 08:52UT the phenomenon was seen again. On May 2nd 
     a bright spot was still seen in the region but it was not changing 
     dimensions. During the observation on Apr 30th the atmospheric
     transparency was excellent. A 2.5" refractor was used. Reference:
     Personal communication from Louderback to Cameron on 1980 Jul 16th.
     The Cameron 2006 catalog extension ID of this TLP was 93 and the 
     weight was 4. ALPO/BAA weight=3.


2018-Apr-01 UT 03:58-04:09 Ill=99% Aristarchus observed by Coates_J on 1978-8-18

     On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor, 
     seeing=II) found that the inner bands of Aristarchus were hard to see, 
     this was odd because the seeing conditions were good and he usually 
     sees them? However he did not believe that there was any obscuration 
     going on. The Cameron 2006 catalog ID=37 and weight=0. The ALPO/BAA 
     weight=1.

     cloud at 05:11-05:18, there were significant dimmings of the 
     brightnesses of Proclus at 05:27. Aristarchus remained constant - this 
     suggested that Clive Brook's earlier report was not a TLP in 
     Aristarchus, but possibly in Proclus which he was using as a

2018-Apr-02 UT 07:52-09:49 Ill=96% Promontorium_Agarum observed by Moore_P on 1996-7-31

     On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300) 
     noticed a lack of detail in the Cape Agarum area - he would normally 
     have expected to have seen some craterlets. However he would not rate 
     this observation much because the seeing was only III and he does not 
     think that it was an obscuration. However just in case he wanted to 
     record this report in the archives. ALPO/BAA weight=1.


2018-Apr-02 UT 09:10-10:11 Ill=96% Alhazen_Alpha observed by Daw on 1972-10-23

     Alphazen Alpha 1972 Oct 23 UT 22:10?-22:13? (Stoke-on-Trent, UK, 
     21cm Newtonian, x217, seeing very good). Flickering colours seen 
     on the north field of Alhazen Alpha mountain. Above UTs 
     estimated by the observer, but the duration of the effect was 3 
     minutes. Colouration centred on the hills that run north to 
     south between Mare Anguis and Mare Crisium. The colour 
     alternated from east to west about 2 or 3 times per second. The 
     colour was not apparent to the north or south, or indeed on any 
     other features. Telescope field of view moved, but effect stayed 
     in the same place on the Moon. Moon't terminator scanned for 15 
     minutes afterwards, but the effect did not recur. The colour 
     seen was mostly red, with a band of orange, and a strip of 
     yellow nearest the hills, the proportions being 6:2:1. The bands 
     seemed to arc up steep above the Moon's surface and flatten out 
     over the mare surface either side of the hill features. No 
     filters were used in the observation. Observer suspects some 
     kind of diffraction spectrum to explain the larger dispersion in 
     the red end of the spectrum. ALPO/BAA weight=3.

     Observations made with a variable polarizer (akin to a crater
     extinction device) to measure brighness with red and blue filters.
     Some variability in brightness noted. With the Kodak Wratten
     25 and 38A filters there was little or no increase in contrast with the 
     red filter, but with the blue filter there was a great increase in 
     contrast of the brighter areas of the crater - the crater floor and 
     patches of lighter material, especially at the north end. The remaining
     areas were supressed with the Blue 38A. ALPO/BAA weight=3.

     Antoniadi I) "A dark discolouration was seen on the east floor, 
     adjacent to the central peak and the dark area on the west floor 
     directly south of the prominent dark area. Hobdell thinks it was a 
     small crater on a secondary rill with slight venting discolooration, 
     seen in Orbiter pictures. A sketch was made and the BAA alerted. The 
     sketch matches the dark spots in Alphonsus (normal aspects?)" cameron

2018-Apr-21 UT 21:19-22:34 Ill=38% 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.

2018-Apr-23 UT 21:55-23:36 Ill=61% 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

     reflector, x80 and x320) using a low power eyepiece, observed that 
     bright craters (but not all of them) "glittered like diamonds". These 
     craters were several on the terminator, Proclus, Censorinus, Manillius, 
     Menelaus and Dionysius. The glitter effect was on the west wall crest 
     -- like stars. Higher power revealed these areas to be bright but not 
     star-like (nor glittering). The Cameron 1978 catalog ID=1212 and the 
     weight=1. The ALPO/BAA weight=1.

     Plato 1789 Jul 30 UTC 21:00? Observed by Schroter (Lilienthal, Germany) 
     NASA Catalog Event #61, NASA Weight=2 (slightly low) Event described 
     as: "Soon after sunrise saw a kind of fermentation on the floor which 
     clearly resembled a kind of twilight, (due to some kind of aberration

2018-Apr-24 UT 03:36-04:01 Ill=63% Eratosthenes observed by Galdies_C on 2012-8-25 *

     On 2012 Aug 25 UT1944-1952 Eratosthenes crater was imaged by C. 
     Galdies (Malta,Nexstar 8SE, Philips SPC 900NC camera). 4 
     Registaxed images were produced covering 19:45, 19:48, 19:49, 
     and 19:51. All but the first image, once first order spurious 
     colour had been removed, showed orange on the shaded terraces on 
     the western illuminated rim (similar to what Paul Abel and 
     others saw in 2009, albeit just confined to the NW rim), and the 
     interior floor shadow was slightly smaller in red light. However 
     orange colour was also seen on the eastern side of mountains to 
     the south of the crater, which infers that the spurios colour 
     removal did not fully acomplish its main goal. The effects were 
     not caused by the registax software as the orange colour is 
     visible on individual images. Although probably the colour is 
     not lunar in orgin, its explanation is not fully explaianed, 
     therfore an ALPO/BAA weight of 1 is used for now.

     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.

2018-Apr-25 UT 21:14-21:51 Ill=81% 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.

2018-Apr-25 UT 21:45-22:04 Ill=81% 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.

2018-Apr-25 UT 23:41-00:51 Ill=82% 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-Apr-26 UT 00:33-02:07 Ill=82% 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.

2018-Apr-26 UT 03:32-04:52 Ill=83% Gassendi observed by Grego_P on 2011-10-7

     On 2011 Oct 07 UT 21:45 Gassendi observed by P. Grego (St 
     Dennis, UK,300m Newtonian, x150, seeing III, intermittent cloud) 
     - whilst producing some sketches of the crater - observer 
     noticed a faint point of light inside the shadow filled 
     interior, two thirds of the way out from where the central 
     peaks should have been, towards the SE rim. Some uncertainty in 
     being sure about this spot and after interuption by cloud it was 
     not seen later that evening. ALPO/BAA weight=1 to refelct 
     uncertainty of observer.


2018-Apr-26 UT 03:53-04:52 Ill=83% Bullialdus observed by Cook_MC on 1979-6-5

     Bullialdus 1979 Jun 05 UT 22:00-23:00 Observed by Cook M.C. 
     and J.D. (Frimley, UK, 12-inch reflector, Seeing III-IV, good 
     transparency). MC Cook observed internittently over this time 
     period (due to cloud) and found the crater sharper in a blue 
     filter than in a red filter. No obscuration seen apart from a 
     darkish patch on the SW rim and spreading over onto an area 
     surrounding the rim, which she took to be shadow, though the 
     main shadow was along the east rim of the crater. JD. Cook 
     observed an orange colouration seen on eastern and the cleft 
     on the SW rim. Dark area seen on southern floor of crater, 
     south of central peak. ALPO/BAA weight=1.


2018-Apr-26 UT 21:13-22:18 Ill=89% 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.

     Torricelli B 2005 Jan 21 UT 21:21-21:43 Observed by North (Norfolk, UK, 
     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."

     reflector, x240) observed Promitorium Laplace to have 
     visually a brown colour - though no Moon Blink (red and blue 
     filters) effect was detected. Cameron comments that this is 
     probably a subjective effect - also others have reported 
     something similar at times. The Cameron 2006 catalog ID=30

     6" Cassegrain, x150 and x180, Seeing 3, high deck of Cirrus clouds) 
     "Torricelli B hard to make out in the videos taken, but images taken 
     through cloud. A check on the image received by the coordinator shows 
     that Torricelli B is in fact visible, but perhaps not very bright. A 
     later observational sequence of images by Raul Salvo (Montevideo, 
     Uraguay UT 03:15-03:23) showed similarly that Torricelli B was dark, 
     and there was some brightness variability although the 
     background setting on these was low" An ALPO report.


2018-Apr-27 UT 03:21-07:16 Ill=90% Aristarchus observed by Grego_P on 1987-1-11 *

     On 1987 Jan 11 at UT 18:15-23:00 P. Grego (Birmingham, UK, 6" 
     reflector, seeing=III) sketched Aristarchus crater and saw two luminous 
     circular patches on the exterior west wall - these were less bright 
     than the inner wall but brighter than the outer wall. The Cameron 1978 
     catalog ID=292 and weight=5.


2018-Apr-27 UT 03:21-07:16 Ill=90% Plato observed by Moore_P on 1987-1-11 *

     On 1987 Jan 11 at UT P. Moore (Sussex, UK) found the the floor of Plato 
     was much more drk than the adjacent Mare Imbrium. Furthemore there was 
     a blurring of detail over the northeast wall and onto the nearby floor. 
     detail elsewhere in the crater was OK. By 23:00UT there was less lack 
     of detail effects. M. Cook (Frimley, UK) at 21:55UT noted the obscured 
     area but decided that it was narrower than the same effect one month 
     ago and suspected that she may have been observing towards the end of 
     this TLP. The effect gradually dimmed between 21:55 and 22:45UT. Other 
     craters were normal. G. North was affected by poor seeing conditions. 
     Davies detected a slight obscurtion on the north east corner - it was a 
     misty gray feature at x200. The Cameron 2006 catalog extension ID was 
     292 and the weight was 5. Tha ALPO/BAA weight was 4.


2018-Apr-27 UT 03:34-05:31 Ill=90% Bullialdus observed by Gray_R on 2006-12-2

     At 03:30UT observer noticed a hint of yellow colour
     on the floor of the crater and by 03:57UT the south
     east and central parts of the floor and the circular
     feature on the south west floor had turned a deep
     yellow colour. The rest of the crater remained colourless.
     Other craters also remained colourless. By 04:05UT the colour
     was fading and by 04:15UT it was gone. Maurice Collins
     in New Zealand took some low resolution colour images about
     4 hours later but these failed to show any yellow colour.
     Zac Pujic obtained colour images at a different time of
     natural surface colour on the Moon and finds that Bullialdus
     does actually have a natural yellow cast to most of the floor.
     However this does not explain the variability in colour strength
     seen by Robin Gray. ALPO/BAA weight=3.

     England, 18" reflector) "I was examining the Cobra Head of the Schroter 
     Valley, when I noticed what seemed to be a diffuseed patch of thin 
     smoke or vapour, apparently originating from the valley on the E. Side 
     where the landslip is, and spread over the edge on to the plain for a 
     short distance. Every detail of the edge of the valley was perfectly 
     clear and distinct except where this patch occurred, but there the

     (Montevideo, Uraguay UT 03:15-03:23) showed that Torricelli B 
     was dark, and there was some brightness variability although the 
     background setting on these images was low and seeing could 
     account for the brightness variation? An ALPO report.


2018-Apr-27 UT 05:26-05:58 Ill=91% Gassendi observed by Darling_D on 1990-10-1

     On 1990 Oct 1st at 00:44-01:24UT D Darling (Sun Praire, WI, USA) 
     observed that Gassendi still had a blink effect when viewed through 
     blue (Wratten 38A) and red (Wratten 25A) filters. No effect was seen on 
     Aristarchus. Gassendi was brighter in the red filter and this was 
     confirmed by Weier. Sketches were made and brightness measurements 
     taken. Both observers used a 12.5" reflector x159. At 01:00UT the NW

     imaged a pseudo-peak with shadow on the floor of Herodotus, 
     however the image scale and quality of this colour image were 
     not great and the observer suspects that it might be an

2018-Apr-28 UT 00:28-02:05 Ill=95% Aristarchus observed by Foley_PW on 1978-5-19

     P. Foley of Kent, UK, using a 12" reflector, seeing=III-II, noticed
     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
     at 00:50UT. Cameron notes that one doesn't get green with spurious 
     colour. Crater Extinction brightness measurements were made at 22:00 UT
     (reading=2.8) and at 23:45UT (reading=3.7). The crater dropped in 
     brightness from 3.7 to 2.8 at 23:50UT and remained lower until 3.0 at 
     23:50-03:15 UT. A graph was produced and showed Proclus and Censorinus

2018-Apr-28 UT 07:49-08:17 Ill=96% Aristarchus observed by Louderback_D on 1988-1-2 *

     On 1988 Jan 02 at 06:41-07:08 UT D. Louderback (South Bend, WA, USA, 
     using a 8" reflector, seeing 4 out of 10) observed that at 06:56 UT 
     Aristarchus floor (point F) brightened rapidly from an intensity of 5.2 
     to 6, however at 07:08 UT the spot returned to normal. He also noticed 
     that the bands on the walls varied every few minutes. A mist like 
     appearance was seen on the floor of Aristarchus. Through a red filter 
     he could see through the haze, but floor detail could not be seen 
     through a blue filter. Cameron 2006 extension catalog ID=316 and

     Plato 1870 May 13 UT 22:00? Observed by Pratt (---), Elger (Liverpool, 
     England), (Gledhill (Brighton, England) "Extraordinary display of 
     lights. 27 seen by Pratt, 28 by Elger, only 4 by Gledhill. (independ. 
     confirm. ?" NASA catalog weight=5 (very good) NASA catalog ID #168.
     A bit more of a detailed report is as follows: "Upon the 13th of May, 
     1870, there was an "extraordinary display," according to Birt: 27 
     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."

2018-Apr-29 UT 23:49-01:46 Ill=100% Aristarchus observed by Amery_GW on 1985-2-4

     G.Amery (Reading, UK, seeing=II) saw a brilliant white rim, 
     bands and central peak. There was also a clearly seen white 
     glare like feature over the ESE wall that had a direction 
     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 
     23:35UT and recorded a brightness of > 4.9. Reported a 
     reversal of spurious colour - Cameron suspects that this was a 
     local effect. No spurious colour noticed by anyone else. 
     However the brightness of the crater was confirmed by other 
     observers. Mosely suspected a brightness change on the inner 
     east wall at a relative position of 8 O'Clock. Cameron 2006

     On 2009 Sep 03 at UT23:15-23:17 B.Gibbs took some hand held digital
     SLR images of the Moon (Sky conditions clear). Four images were taken 
     at: 23:14:53, 23:15:59, 23:16:05 and 23:17:23 (uncertainty +/-15 sec 
     offset from actual UT). These showed some apparent variation in the 
     brightness of Aristarchus. However there are ways toexplain this 
     through image motion blur when the images were taken. However we 
     cannot be absoultely sure. The ALPO/BAA weight=1.

2018-Apr-30 UT 03:34-04:59 Ill=100% Aristarchus observed by Darling_D on 1990-12-2

     F. Graham took some photos of the Cobras Head and found a blue cloud 
     about 50 km in diameter and scattering light - Cameron says that 
     this indicates high density. Darling found the Cobra's Head obscure and 
     variable "clear and bright to diffused". Cameron was alerted observed 
     (02:40UT) variations with periods of approximately 30 seconds, and 
     thought that she could see a red tinge on the east rim of Aristarchus - 
     checks elsewhere found no other colours. Darling found that a blue 
     filter enhanced the effect and a red filter made it disappear. There 
     was a blink at 02:55UT but no blink in the Cobra's Head, which looked 
     fuzzy and lacking in detail. The effect was confirmed by Weier, who 
     also saw two dark spots in the Cobra Head in blue but not in red light. 
     The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall 
     7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south 
     wall 7.0, East wall 8.0, and the central peak 10.0. Observer details 
     were as follows: Darling (Sun Praire, WI, USA, 12.5" reflector, x159,
