2019-Feb-07 UT 19:47-21:51 Ill=8% Aristarchus observed by Celis on 1969-10-14 *

     On 1969 Oct 14 at UT 00:00-00:30 Celis et al. (Valparaiso, 
     Chile, seeing=good and transparency=good). observed Aristarchus 
     and found it to be: "Scintillating in irreg. way. Pulses of 1m

     On 1983 Feb 15 at UT 18:00? G. Amery (Reading, UK) found that he could 
     not see Aristarchus in Earthshine, despite less normally priminent 
     features being clearly seen. This observation was confirmed. Other 
     observers were: Moore, Cooks, and Foley. The Cameron 2006 catalog ID=

     On 1990 Jan 01 at UT 16:55-18:45 H. Miles (Cornwall, UK) observed that 
     Aristarchus was seen in Earthshine at 16:55UT before the limb (was 
     visible in Earthshine?). "1705 Aris>>1723 fading 1727 > again." Then: 
     "1740 Aris << and just visible at 1845". Apparently Foley suspects that 
     Aristarchus had brightened up before 16:55UT (shwen H. Miles started to 
     observe) and then gradually retruned to normal. The Cameron 2006

2019-Feb-10 UT 19:35-20:47 Ill=29% 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.

2019-Feb-10 UT 19:35-20:29 Ill=29% Proclus observed by Darling_D on 1989-2-11

     On 1989 Feb 11 at UT23:30-01:39 D. Darling (Sun Praire, WI, USA, 12.5" 
     reflector, x159, seeing=7/10) observed a linear east to west feature in 
     Proclus. D. Weier (WI, USA, 11" reflector, x378) found the NNW part of 
     the crater to be brighter than expected and confirmed the prescence of 
     the east to west feature - this crossed the shadow on the east floor 
     and over into Mare Crisium. R. Manske (WI, USA) detected another 
     "streak" parallel to this. All observers suspect that the linear 
     features were due to raised topography on the floor of Proclus - 
     however Cameron comments that there does not seem to be any linear 
     features on the floor of Proclus to cause these effects. The Cameron 
     2006 catalog ID=351 and the weight=5. The ALPO/BAA weight=2.


2019-Feb-10 UT 19:35-20:40 Ill=29% Santbech observed by Rogers_G on 1994-6-14 *

     On 1994 Jun 14 UT 21:45-22:00 G.Rogers (Crendon, UK, 3" Zeiss 
     refractor, sky conditions perfectly clear) reported seeing three 
     very large whitish clouds against the Moon. The strongest seemed 
     to "stem" from the vicinity of Santbech crater (crater 
     identified the next day from an atlas), and was a milk chocolate 
     colour near the stem. The other two large clouds were to the 
     north - in the general area of Mare Fecunditatis and Mare 
     Crisium though perhaps slightly further west and in contact with 
     the terminator? The effect was confirmed (independently) by 4 
     other observers using the same telescope. The telescope was 
     moved but the clouds remained in the same position over the 
     Moon. This report comes from The Astronomer Jan 2013 p 230.

     transparency good) "Observations carried out of the area extending from 
     the Alpine Valley to the Crater Cassini. At 17:12 a pin point bright 
     flash was seen NW of the rim of the crater E in white light. A 2nd pin 
     point flash was also seen at 18:18, this time thru a blue filter. The 
     2nd flash was also seen on the NW rim of the crater E. The observer 
     does not think this was a TLP as the seeing was III, but the flash was 
     so bright as to be startling. Other peaks within the Alps were bright 
     but were much less so in red and ble filters, where the rim of the 
     crater E. NW edge was very bright in all filters, including white 
     light. Incoming cloud prevented further observation." BAA Lunar Section

2019-Feb-12 UT 23:27-01:15 Ill=50% 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.


2019-Feb-12 UT 23:42-01:25 Ill=50% Aristarchus observed by Foley_PW on 1988-2-25

     On 1988 Feb 25 at UT20:00? P.W. Foley (Kent, UK, 12" reflector) found 
     that Aristarchus was very bright (especially in the UV end of the

2019-Feb-13 UT 01:39-02:24 Ill=51% Alphonsus observed by Kane_D on 1993-6-27

     On 1993 Jun 27 at UT 19:55-20:21 and 20:24-21:04) D. Kane (England? UK, 
     4" refractor) discovered that the central peak of Alphonsus crater was 
     very bright. The central peak was also brighter in red than in blue 
     light. However G. North (Herstmonceux, UK, 6" reflector, x135, seeing 
     V-III) and M. Cook (Frimley, UK, 4" reflcrctor, x10, seeing=III) 
     observed that the central peak was normal, however they did not use

2019-Feb-13 UT 19:45-21:05 Ill=60% Aristarchus observed by Madej_P on 1984-12-31

     Although the crater was on the night side, a small bright spot
     was seen. This was blue, almost UV, and equivalent to a star of
     magnitude 2. It flashed over intervals of about 30 seconds
     and changed in colour from UV to blue. The BAA Lunar Section
     TLP network was alerted. Mobberly and J.Cook did not see much
     although J. Cook may have seen something, but located else where?
     Cameron lists this as a confirmed? observation? The Cameron
     2006 TLP xtension catalog has this TLP with an ID No. of 258
     and a weight of 4. The ALPO/BAA weight is 2.


2019-Feb-13 UT 21:39-22:46 Ill=60% Plato observed by Moore_P on 1995-9-3

     On 1995 Sep 03 at UT19:40-20:15 P. Moore (Selsey, UK, 15" reflector at 
     x400) observed that the floor of Plato was much darker than he would 
     normally expect and futhermore no interior craterlets were seen. there 
     was however a white patch that was barely visible at the location of 
     the central craterlet should have been. G. North (UK) attempted to 
     observe nut the Moon was too low and seeing terrible. F. Doherty 
     reported Plato normal. Cameron 2006 catalog ID=475 and weight=3.

     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.

2019-Feb-14 UT 01:11-03:08 Ill=62% 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.


2019-Feb-14 UT 01:11-03:08 Ill=62% 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

2019-Feb-15 UT 03:16-03:27 Ill=73% 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-Feb-15 UT 03:25-05:01 Ill=73% 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.

     On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5" 
     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

     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

2019-Feb-16 UT 03:50-05:00 Ill=83% Gassendi observed by Unknown_English_Observer on 1977-4-29

     On 1977 Apr 29 at UT21:40-23:20 an unknown UK observer reported a TLP 
     in Gassendi crater. The following are reports by observers attempting 
     to confirm activity: J.W. Napper (Didcot, UK, 30cm reflector, x287, 
     Wratten 25 and 44a, conditions clear 5+) received a telephone alert 
     call at 22:00 but the sky was cloudy until 22:30. An initial look 
     revealed nothing unusual, then at 22:54 he observed a colour blink just 
     inside the north wall, appearing bright in red and normal in blue or 
     white light. No loss of detail seen and the effect lasted only 2 
     minutes. A sketch was made. However the observer stresses that the very 
     bad seeing casts some doubt on this observation. L. Fitton observed 
     using a 8.5" reflector, with Moon blink device at x200, seeing was I-
     II. All areas negative, including Gassindi from 21:40-21:55 and again 
     22;00-22:25 and finally 22:50-23:30 negative. Mike Brown (Huntington, 
     York, UK, 30cm reflector, x220 and x350, seeing 3-4/5, and transparency 
     5/5) - observed from 22:00-23:25UT no colour seen, nor obsecuration, 
     all filters negative, despite seeing a lot of fine setail inside this 
     crater.


2019-Feb-16 UT 04:15-06:02 Ill=83% Gassendi observed by Robinson_JH on 1976-10-4

     Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon, 
     England) - observer noted that the east outside wall was bright in red 
     and normal in blue. Note that the Moon was 30 deg above the horizon at 
     the time of the observation. The crater returned to normal at 20:58. 
     Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D. 
     Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at 
     times) noticed a possible obscuration over the southern part of 
     Gassendi. He had been observing earlier at 18:40-19:30 but had not 
     detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot 
     outside the east wall is again bright in red., though by 22:25 it had 
     faded  and was gone by 22:28UT. The Cameron 1978 catalog further 
     quotes: "Vivid red spots & general red color seen around rim by 2 obs. 
     At 2209h blood red small area was seen. 1 h later the most westerly 
     (IAU?) of the peaks had become hazy white all other areas were sharp.

     15. At 02:00 he observed pink on the south west wall of Aristarchus 
     crater. At 01:24UT the Aristarchus ray was yellowish, however the 
     entire Moon had a grey-yellow tinge of colour. Chromatic aberation was 
     observed at 01:56UT. By comparison Gassendi was checked and had no 
     colour. At 02:10 the crater wall of Aristarchus was unusual and was

     (Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5, 
     x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red 
     25. The illuminated west crater wall stood out brilliantly in blue 
     light, much more so than in white light. This was true also of 
     Aristarchus. Red light did not increase contrasts in Herodotus any more 
     than they were in white light. Shadows in Herodotus appeared as black 
     as the night west of the terminator and remained that way throughout 
     the observing period. No TLP seen in Herodotus tonight. A possible TLP 
     was seen to the west of Herodotus near the terminus of Schroters 
     Valley. It was noted at the beginning of the observing period that 
     there were four very bright spots of light, one near the end of 
     Schroters Valley, the other three grouped together a little farther 
     north. Although not far from the terminator they were definitely east 
     of it. It was noted that all of them nearly vanished in the Blue 38A 
     filter while Aristarchus and the rim of Herodotus gleamed brilliantly. 
     At 5:19UT it was noted that the most brilliant of the four lights, the 
     one near the terminus of Schroters Valley, had faded almost to 
     invisibility in white light. When first seen it had been brighter than 
     Aristarchus. It remained very dim after this through the remainder of 
     the observing period, and was unchanged at 7:35-7:49UT when I again 
     examined the area. The other three bright spots remained brilliant and 
     unchanged."

2019-Feb-17 UT 03:34-05:24 Ill=91% 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

2019-Feb-17 UT 20:28-21:54 Ill=95% Plato observed by Foley_PW on 1978-8-16

     Peter Foley (Kent, UK, 8" reflector, seeing=II) noticed that
     the floor beneath the north wall, and the area over the north
     wall were indistinct (almost out of focus). Despite looking
     elsewhere in the crater and surrounds, no other blurring
     (obscuration of detail) could be seen, indeed everywhere else
     was sharp and detailed. Foley tried several eyepieces but this
     made no difference. He used a crater extinction device but
     found no variations in brightness. There was a slight
     darkening when he used a red filter in the Moon Blink device.
     The obscuration effect weakened between UT20:56 and 21:10,
     was difficult to see at 21:13 and had finished by 00:15.
     Patrick Moore (12" reflector, Dublin, Ireland) saw nothing 
     unusual when he started observing at UT 22:00. Cameron says 
     "Photos marked at location of phenomenon". Cameron 2006

     Aristarchus normal in red and blue filters however the
     Cobra Head part of Schroter's Valley was brighter in blue.
     Indeed it was very dull in red - Louderback says that this
     was not surprising as the whole areas around Aristarchus is
     brighter in blue. Louderback is an experienced observer
     of the Aristarchus area of more than 10 years. Cameron 2006

2019-Feb-17 UT 21:35-22:30 Ill=96% Aristarchus observed by Louderback_D on 1985-12-25

     Louderback observed that the south west wall was a creamy deep yellow.
     There was also strong fluorescent blue on the west wall of the Cobra
     Head - Schroter's Valley area and this was similar to the violet glare
     seen on Aristarchus at times. Violet was seen between Aristarchus and
     the Cobra Head. Seeing coditions were poor. Brightening of a point
     near C occurred roughly every 10-15 seconds and lasted 0.5 sec -
     (Cameron concludes that this was not due to the Earth's atmosphere).
     A 0.2 step drop in brightness was seen on point A (twin spots).
     Point C had reduced by 0.6 steps. Elsewhere was stable in brightness.

     A bit more of a detailed report is as follows: "Upon the 13th of May,

     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."

     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

     think that it was an obscuration. However just in case he wanted to 
     record this report in the archives. ALPO/BAA weight=1.


2019-Feb-21 UT 04:37-06:33 Ill=96% Proclus observed by Savill_AM on 1973-11-11

     Proclus 1973 Nov 11 UT 20:40-23:05 Observed by Savill 
     (Cambridge, England, 12" refractor, x100?), Young (Yorks, 
     England), Pedler (Bristol, England, 6" reflector?), Livesey 
     (Scotland). "At 100x showed a bright spot in S.part of crater. 
     At 300x was vis. but power too high. In 8-in refr. at 170x, at 
     2055h 2 spots present. Confirmed by Young. Seeing was 
     improving. At 2104h in 12-in refr. at 260x the lower spot 
     seemed distinctly enlarged & vaporous. Decided it was due to 
     poor seeing. Later the 2 spots were better defined & separated 
     but lower moved away fr. larger one & they seemed more 
     separated than earlier. Obs. ended at 2305h when they decided 
     it was not an LTP. but was 2 craters instead of humps. There 
     were neg. repts. from others at the same time. (there are no 
     craters in Proclus)." NASA catalog weight=2. NASA catalog ID #
     1382. ALPO/BAA weight=1.

2019-Feb-21 UT 07:03-08:42 Ill=96% Aristarchus observed by Cook_MC on 1990-12-3

     On 1990 Dec 03 at UT23:00-01:30 M.C. Cook (Frimley, Surrey, UK) noticed 
     that the central peak of Aristarchus was quite bright and extended to a 
     circular region in the east in the crater "sprout" area - Cameron 
     suggests that this is Bartletts self defined EWBS area?. Beyond the rim 
     to the east was very bright. However no colour effect was seen in 
     filters. A sketch was supplied. Cameron notes the coincidence of 
     perigee and full Moon. The Cameron 2006 catalog ID is 416 and the 
     weight=3. The ALPO/BAA weight=1.

2019-Feb-22 UT 03:20-04:20 Ill=91% Aristarchus observed by Cook_MC on 1990-1-14

     On 1990 Jan 14 at UT 01:14-01:55 M.C. Cook (Frimley, UK, seeing=poor) 
     observed that Aristarchus did not appear normal for this illumination. 
     the northern half of Aristarchus was "2x>" than the southern half of 
     the crater. There were two white patches of apron material near to the 
     crater Herodotus that were 50% of the brightness of the southern half 
     of Aristarchus. Furthermore the southern half of Aristarchus had a 
     circle - "dull patch on inner S wall with a bright point shining 
     through it. (Bartlett's EWBS?)". The Cameron 2006 catalog ID=389 and
