2020-May-01 UT 00:00-00:07 Ill=52% Alphonsus observed by Jasmin_G on 2003-4-10

     On 2003 Apr 10 at 00:40UT a GLR observer G. Jasmin (Quebec, Canada, 
     using a 10" F-10 Schmidt Cassegrain) took a photograph of Alphonsus 
     crater on Kodak 400ASA film with an exposure of 1/30th sec. There was a 
     light visible (diameter 10 km) inside Alphonsus and the effect was 
     present for 5 minutes. The observer commented that they have seen a 
     light in this crater many times before, but never as long as 5 minutes.
     This report was submitted to the GLR group in Italy. The ALPO/BAA 
     weight=2.


2020-May-01 UT 00:00-01:07 Ill=52% Chacornac observed by Khachatryan_S on 2009-8-28

     On 2009 Aug 28 at UTC 17:00:15-17:00:42 S. Khachatryan (Yerevan, 
     Armenia, 127mm Maksutov-Cassegrain, x171, seeing 9 (1=worst and 10-
     best), Transparency 5-6 on a scale of 1 to 6) observed in the Chacornac 
     area a series of fiery sparks (dot like with tiny rays), slightly 
     elongated with the multitudinal rays orientated towards the south west 
     direction. The colour was mostly red, with some yellow. The final flash 
     was the most clear. The TLP was tiny in area, but "was distinctly 
     bright against any other object on the Moon". The positional 
     uncertainty of the location of the spark effect was approximately +/-
     150 km, based upon an examination of an atlas afterwards. Just prior to 
     the spark effect, something dark, small and fuzzy (only just discrnable 
     to the eye, through the eyepiece) was seen to pass from the west across 
     the Moon in a slight curve, round the surface of the Moon to the east 
     (post observation estimate: seen for 3.5 sec and covered roughly 8% of 
     the lunar diameter in that time). The area of the dark object was 
     comparable in size to (or slightly less than?) craters such as 
     Autolycus F (diameter 3km) or le Monnier E (diameter 4km) i.e. on the 
     limits of vision of the scope used. The location of the flash was not 
     exactly at the same location as the dark object passed across, but gave 
     the impression of starting from it? A back of the envelope calculation 
     of the lunar diameter covered in the time quoted gives an approximate 
     speed (at the lunar distance) of 80km/s or on the very high end of 
     typical meteor streams that pass by. At closer distances, and 
     recalculated velocities, it is unlikely to be a satellite in low Earth 
     orbit (20m/sec at 100km distance), but could perhaps be a bird or 
     insect at a few km range? So was this dark object something in our
     atmosphere by chance passing across the field of view close to the time 
     of the TLP flare or was at the lunar distance and related to the TLP? 
     Incidentally, no attempt was made during this observation to move the 
     scope to check that the TLP remained stationary against the Moon. The 
     ALPO/BAA weight=2.

2020-May-01 UT 02:59-06:04 Ill=53% 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.

     says that 7 persons have seen this over a 2.5 year period. The Cameron 
     1978 catalog ID=801 and weight=1. The ALPO/BAA weight=1.


2020-May-01 UT 23:39-00:59 Ill=63% Gassendi observed by Moore_P on 1967-2-18

     Gassendi 1967 Feb 18 UT 20:30-20:40 Observed by Moore, Moseley

2020-May-01 UT 23:39-23:50 Ill=63% Messier observed by Robinson_JH on 1979-7-3

     On 1979 Jul 03 at UT 20:55-21:20 J-H. Robinson (Teighmouth, Devon, UK, 
     10" reflector, seeing II) observed that Messier was brighter than 
     Messier A. No colour was observed. The Cameron 2006 catalog ID is 58 
     and the weight=3. ALPO/BAA weight=1.


2020-May-01 UT 23:39-23:50 Ill=63% Tycho observed by Albert_J on 2010-8-19

     On 2010 Aug 19 at UT 00:50-01:02 J.Albert (Lakeworth, FL, USA, 
     C11, Transparency 3, Seeing 7-8, 86F and very humid. Oberver 
     checking out repeat illumination condition appearence for Tycho 
     concerning LTP #468 in the 1978 Cameron catalog. Did not see the 
     effect from the original TLP report, but did see, immediately at 
     looking at Tycho a very faint hint of redness in a pencil thin 
     arc (< 1/4 circumference of the rim) confined to the top of the 
     rim of the well-lit north east wall. Coloured arc similar in 
     thickness to Rupes Recta, but not as sharply defined. The outer 
     (E) edge was perhaps sharper than the inner edge. The redness 
     was more on the inside of the top of the rim. The outside of the 
     rim was bright white. This effect was seen in three different 
     eyepieces, at 311x, 224x and 400x. Checked for the effect on 
     other craters nearby but could not see this effect anywhere 
     else. The colour had dissapeared by 01:02UT. The fade took about 
     1-2 minutes. Observation of Tycho continued until 01:06UT, but 
     all seemed normal. Quick checks were made again on Tycho 
     periodically until 02:50UT but the colour was not seen again. 
     ALPO/BAA weight=3.


2020-May-02 UT 00:06-01:31 Ill=63% Aristarchus observed by Robinson_JH on 1980-5-23

     On 1980 May 23 at UT21:14-21:55 J.H. Robinson (Teighmouth, Devon, UK, 
     12" reflector, seeing II-III) could see Aristarchus in blue and clear 
     filters, but not in red light. Robinson saw some variability in this 
     effect with time. Cameron 2006 catalog ID=96 and weight=3. ALPO/BAA 
     weight=2.


2020-May-02 UT 00:06-01:31 Ill=63% Copernicus observed by Blair_G on 1980-5-23

     On 1980 May 23 at UT21:14-22:18 G. Blair (Bridge of Weir, 
     Scotland, UK, 216mm reflector, seeing II-IV) found a red tinge 
     along the western wall of Coperncius, perhaps 32km in length. 
     This was invisible in a blue-green Wratten 44a filter, but was 
     unmistakble in a red Wratten 25 filter. Could have been 
     spurious colour - but no other regiosn were affected. The 
     ALPO/BAA weight=2. 


2020-May-02 UT 00:06-01:31 Ill=63% Littrow observed by Petek on 1980-5-23

     On 1980 May 23 at UT 21:14-21:18 Marco Petek (Porto Alegre, 
     Brazil) saw in the region of Littrow and an area of dark mare 
     south west from Littrow to Argaeus, abnormal darkness, and a 
     rapid change of form. He also saw a shadow extending south 
     east from Campanus opposite to the Sun - however Foley thinks 
     this is normal. Cameron 2006 catalog ID=96 and weight=0 or 1. 
     ALPO/BAA weight=1.


2020-May-02 UT 00:20-02:07 Ill=63% Copernicus observed by Firsoff on 1955-7-28

     Copernicus 1955 Jul 28 UT 20:20 Observed by Firsoff (Somerset, England, 
     6.5" reflector x200) "Great brilliance of the terraces in E(IAU?) wall 
     system(?) gets specular refl. (he gave 0820UT, but must have meant 
     2020" NASA catalog weight=4 (high). NASA catalog No. #600.


2020-May-02 UT 00:58-02:53 Ill=63% Atlas observed by Andre on 1966-12-21

     Atlas 1966 Dec 21 UT 17:10 Observed by Andre (Belgium, 3" refractor) 
     "Bright spot on SE part of floor, not seen in photo on 12/18/66" NASA 
     catalog weight=2 (low). NASA catalog ID #1003.


2020-May-02 UT 01:02-02:35 Ill=63% Aristarchus observed by Spencer_S on 1976-6-6

     Aristarchus 1976 Jun 06 UT 21:30-21:40 S.Spencer and R. Hunt 
     (60mm refractor, x150 and x60) both observed red on the SW 
     corner of Aristarchus. ALPO/BAA weight=1.


2020-May-02 UT 01:05-02:59 Ill=63% 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.


2020-May-02 UT 01:10-02:35 Ill=63% 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. 


2020-May-02 UT 01:23-02:47 Ill=63% 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.


2020-May-02 UT 01:30-02:36 Ill=63% Copernicus observed by Darling_D on 1990-8-30

     On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" 
     refractor, x90, seeing conditions: "at,. boiling") noted a coloured 
     area on the west wall of Copernicus that was unusual in appearance - 
     however other craters along the terminator had a similar effect. There 
     was also a "dazzling bright spot on the E. rim and he witnessed 6 
     flashes from the lighted part of Copernicus over a very short time 
     interval. Cameron comments that the colour may well have been dur to 
     chromatic aberation because a refractor was used. The Cameron 2006 
     catalog ID=408 and the weight=0. The ALPO/BAA weight=1.


2020-May-02 UT 01:30-02:36 Ill=63% Proclus observed by Darling_D on 1990-8-30

     On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" 
     reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc. 
     bright interior uniform gray". The Cameron 2006 catalog report is 
     slight unclear as the description for thnis 1990 Aug 30 TLP also 
     includes Copernicus and Censorinus in the list of TLP craters. So one 
     description which might refere to Copernicus, could possibly have been 
     meant for Proclus, namely: "Dazling bright spot on E rim. Rotated 
     eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog 
     ID=408 and weight=0. The ALPO/BAA weight=1.


2020-May-02 UT 01:55-03:49 Ill=63% 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.


2020-May-02 UT 03:18-04:59 Ill=64% Proclus observed by Classen on 1969-11-18

2020-May-02 UT 03:41-06:40 Ill=64% Vitello observed by Unknown_Observer on 1960-8-1 *

     On 1960 Aug? 01 at UT 22:00? an unknown observer detected that Vitello 
     was illuminated -it should have been in shadow? Cameron says that if 
     several days before sunrise then the date could have been July through 
     to December, with August 1st most likely, and ancilary data is 
     therefore given for this date. The Cameron 1978 catalog ID=729 and 
     weight=1. The ALPO/BAA weight=1.

2020-May-03 UT 02:13-04:07 Ill=74% 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.

2020-May-03 UT 03:06-05:00 Ill=75% 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.

     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

     reflector, x159) observed an "anomalous black bar across Aris. Nearly 
     digonal to terminator." The nearby crater Prinz had curious shadow 
     patterns, perhaps related to the rising sun projecting shadows from the 
     eastern rim and "reflected down"? "At 0224 W wall had a break in it & a 
     diffuse glow where it should not be. Manske thinks it was Earthshine 
     effect. At 0305 Weier saw Manske's bar - with diffused light and 
     flicker like an aurora - like a gas with electric charge. At 0325 saw a 
     strange glow in Aris. but may be due to atm. though thought it to be a

     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

2020-May-05 UT 03:11-05:05 Ill=92% Aristarchus observed by Foley_PW on 1984-1-15

     Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore 
     (Sussex, UK) saw the wall as normal. However Cameron points out that 
     Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely 
     (Covington, UK) at 22:10 UT noticed a brightening on the East wall and 
     at 01:10-01:25 UT suspected that the interior had a weak yellow-green 
     cast to it. Cook (Frimley, UK) states that orange colour was within the
     interior crater, but green beyond the east rim at the 9 O'Clock and
     the south east corner to floor blue/mauvre beyond the northern rim 
     NW/WSW. Foley sstates that orange and blue/mauvre might be spurious 
     colour, but green one cannot get this way. Cameon suggests chromatic 
     aberatons as a possibility but thinks that the observers concerned were 
     experienced enough to recognize this if it were the cause. Cameron 2006 
     catalog extension ID=239 and weight=0. Moore used a 15?" refletor and 
     Foley used a 12" refletor. Mosely experienced II seeing and good

     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

     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

2020-May-07 UT 06:31-07:19 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

2020-May-08 UT 02:56-05:12 Ill=99% Aristarchus observed by Porter on 1978-8-19 *

     On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a 
     6" reflector, Seing = 6/10) noticed blue on the north east corner of 
     Aristarchus and an orange glow on the south east wall. They detected no 
     movement or change in brightness. The observer used both eyes, to make 
     sure it was not an eye defect, and three filters: red Wratten 25, blue 
     Wratten 82 and Violet Wratten 47. Porter found that the colours faded 
     for a duration of 5 minutes and then returned. Their right eye gave a 
     good view and using their left eye they suspected that it was 0.5 steps 
     brighter than the remainder of the crater. The suspected colour 
     remained visible, even under moments of good seeing conditions. The 
     colour eventually faded over time and was eventually gone. Porter 
     reportd seein gcolour here on the following night. Apparently other 
     bright spots showed no colour. Fitton suggests that the filters used 
     confirm that the south east wass was definitely red in colour. The

     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.

     the colour over to the external ray. Cameron also comments that 
     Louderback's refractor would refract more in blue light than in yellow, 
     therefore she did not think that it was due to chromatic aberation. The

     On 1985 Apr 25 at UT 21:34-22:04 H. Miles (England) observed 
     Aristarchus within Earthshine. Foley (Kent, UK, 12" reflector) had 
     observed it one hour prior to Miles and found it to be both dull and 
     blue - with a bright patch west of the crater on Aristarchus Upsilon 
     Mountain. At 21:45UT 6 star-like flashes seen on the floor. They 
     occurred again a few minutes later and repeated at 22:04UT.By 21:45UT 
     the bright patch had gone though. Smith (England) had also apparently 
     seen the flashes and a further glow, albeit more north of the one seen 
     by Foley. Miles confirmed Smith's glow north of Aristarchus. 
     Peters did not see much, indeed found Aristarchus to be quite 
     faint (2130-2141). The Cameron 2006 catalog ID=264 and the

2020-May-28 UT 02:06-02:35 Ill=28% Torricelli_B observed by Cook_MC on 1985-4-25

     Curious lack of detail, but this may have been related to
     the seeing. Of greater interest though was a dark blue
     splodge where the crater should have been. Shadow seen through
     this splodge, but no crater rim seen.

     Aristarchus appeared to glow in Earthshine with a faint 
     green luminescence that moved from side to side. A bright
     blue central spot was also seen. The green colour was detected
     in two seperate eyepieces.  Observation made from England.

     On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a 
     10" reflector at 32-64x) noticed that Aristarchus was not 
     visible, although the Earthshine was very obvious. Foley (of 
     Kent, UK, and using  12" reflector) noticed that the crater was 
     only just visible but Plato could definitely be seen. Cameron's

2020-May-29 UT 02:30-03:15 Ill=38% Aristarchus observed by Johnson_G on 1985-4-26

     G Johnson of Swanton, MD, USA used a 2" refractor at f/12.
     Aristachus revealed as a red spot on a photo of the Moon. This
     was similar to another photo obtained on 1988 Apr 21st. Frame (with 3
     exposures present)reveals a dim star like point near Campanus on 
     exposure 1. Expsoure 2 shows it a little east on the Earth-lit 
     part. Exposure 3 shows it off the south-east limb. Apparently 20
     minutes later took 2 exposures and frame 18 was a double. The
     second exposure revealed an object farther from the limb but the
     first exposure does not show the object. The two high power exposures 
     do not show it. Cameron could not see the spots that Johson describes
     on his slides, but did see several spots (defects?) on the 
     8 and 12 second exposures near Hevelius and also on the 20 second
     exposure near to Hecataeus only. BAA members observed star like 
     flashes a few hours earlier - near Aristarchus. One BAA member, Madej, 
     had seen a green glow in Arisarchus in two places in two eyepieces.

     On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia) 
     noted that Mons Piton was too bright near the terminator and was 
     surrounded by shadow. A sketch was made. The mountain appeared 
     segmented with one thin shadow line. The mountain looked like a 
     Mexican Sombrero hat. This appearance is normal. What was 
     abnormal was that Piton was brighter than Proclus, and only 
     slightly fainter than Censorinus. The CED brightness 
     measurements were normal Piton=3.6, Proclus=3.5 and Censorinus=
     3.7. Please check to see whether this is still the case. The

2020-May-30 UT 02:29-03:49 Ill=49% Aristarchus observed by Mobberley_M on 1985-4-27

     Mobberley and Foley note that Aristarchus was very
     prominent in Earhshine. Little other detail seen
     in Earthshine other than the limb. The Cameron
     2006 extension catalog then says: "Confirm moving 
     side to side. Saw bright blue spot in center" however 
     it is unclear whether this refers to Aristarchus,
     or Torricelli-B - the latter was also undergoing a TLP
     at this time. Cameron 2006 extension catalog ID=267

     " 02:26 U.T. Sunrise on Tycho 3/4 of the crater was in shadow, 
     topmost section of the central peak was in sunlight. In white light 
     brightness of the central peak rivaled the brightness of the Eastern
     (sunlit) wall. No change was detected in red light, however in blue 
     light definite strong darkening was observed. Blink obtained when 
     viewing thru 25A and 38 filters. At 2:52 U.T. in the poor to fair 
     seeing the apparent size of the central peak in white and red light was 
     the same, in blue light the central peak in white and red light was the 
     same, in blue light the central peak size shrank to 1/2 white and red 
     size (and brightness). Also appearing sharper. Comparison was made also 
     with the central peak of Alphonsus, no changes were observed. The 
     significant part of the observation was the relative brightness of the 
     central peak to the sunlit rim in white and red light, they appeared 
     almost identical with the crater rim, being just slightly brighter. In 
     blue light the brightness of the central peak was reduced by at least 
     half while the rim brightness was not, (relative to one another). I 
     strongly believe that this was a real event. The shadow filled 
     portion of Tycho was examined for any abnormalities but none 
     were observed. Observations were ended shortly after 3:14 U.T. due to 
     clouds. I also conducted about 20 Moon blink observations during this 
     observing run and got the same strong reaction each time." ALPO/BAA
