2018-May-01 UT 00:43-02:27 Ill=99% Aristarchus observed by Mellor on 1978-5-22

     Aristarchus was not normal, but all the following features were: Mare 
     Crisium, Proclus, Sinus Iridium, Grimaldi, and Tycho. Observed by 
     Mellor and Fitton, UK. Observer notes that Aristarchus is brighter than 
     Tycho when normal. Estimated variation was 25%. However the Moon was 
     low and the Moon was yellow. Despite this the observer decided that the 
     effect was real. Cameron 2006 extension catalog ID=32 and weight=2. 
     ALPO/BAA weight=1.


2018-May-01 UT 00:48-02:45 Ill=99% Aristarchus observed by Moore_P on 1977-7-1

     P Moore, Selsey, Sussex, UK, used a 5" x250 scope and between
     23:50UT on Jul 1st 1977 and 00:10UT on Jul 2nd 1977 observed
     Aristarchus. The south wall of the crater was reddish, extending 
     down to the outer south east wall (IAU). However seeing was no 
     better than III-IV and he was 99% sure that the colour was 
     spurious. His report was submitted only in case any other 
     observers reported something similar. ALPO/BAA weight=1.

     On 1955 Oct 02 at UT 05:30-05:55 Bartlett (Baltimore, MD, USA, 3.5" 
     reflector, x100, S=7, T=5) observed the following in Aristarchus 
     crater: "Viol. gl. on E, NE rim, over EWBS resembled a viol. mist. 
     Crater itself was hazy, could not get a sharp focus". The Cameron 1978 
     catalog ID=615 and weight=4. The ALPO/BAA weight=2. 


2018-May-01 UT 04:22-06:09 Ill=98% Torricelli_B observed by Mobberley_M on 1985-12-27

     Mobberley noticed that Torricelli B was bright and had an even brighter 
     spot on the inner north wall. The observation was made from UT19:45-
     21:40 using visual and video techniques. There was also a bright region 
     NNE of Toricelli B, that was noticed. Foley examined the video and 
     found that the crater faded in brightness over time and also the bright 
     area to the NNE was not as bright on video as had been seen visually. 
     Foley speculates that because the CCD camera was sesnitive to the near 
     IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and 
     also saw the bright spot on the inner north wall - but saw a blue halo 
     around the crater. Response in blue filter, darkening over whole 
     region. Brightness measures with a crater extinction device (CED) 
     indicated that the crater was 80-85% the brightness of Censorinus. 
     There was a bright area NNE of the region. M. Cook observed 22:10-
     22:16UT (15cm reflector and seeing III-IV) and also saw that the crater 
     was very bright indeed with a spot NNE of the region (same position as 
     28/28 1985 observation) - suspected that the crater might have been 
     brighter than Censorinus, but judgement effected by seeing. In a blue 
     filter the crater dulled leaving the bright spot prominent (but only 
     during a good moment of seeing) - therefore had some suspicion of 
     seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the 
     area, but the seeing was even worse - but did manage a check of the 
     brightness of Torricelli B to Censorinus and now made it one quarter of 
     that of Censorinus and no sign of the crater dimming in the blue as had 
     been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at 
     21:15UT (Dec 27) thought that Torricelli B looked normal and saw no 
     colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images 
     through red+IR (Wratten 25) and IR (Wratten 87) but found no colour 
     differences, though there was a very slight hint that a brightness fade 
     may have occurred between those two observing times. Note that this
     report does not have an entry in the Cameron 2006 Extension Catalog.
     The ALPO/BAA weight=4.


2018-May-01 UT 06:02-07:59 Ill=98% Aristarchus observed by Madej_P on 1984-2-17

     On 1984 Feb 17 at 19:45-22:20UT P. Madej noticed colour in Aristarchus 
     and telephoned the BAA Lunar Secton TLP network. Mosely at 21:15UT 
     observed that Aristarchus was both bright and fuzzy - there was some 
     spurios color (red on south and blue on the north) but this was 
     replaced by violet. By 21:30UT (transparency=fair) the centre of the 
     crater was bluish and the west wall creamy white. the north and south 
     walls were brilliant white. By 22:00-22:30 UT the seeing had improved 
     and the crater looked unusual - now the centre was violet and the west 
     wall duller, off-white. By 05:35UT the crater was difficult to define 
     according to Cook - 4 bands could be seen under II seeing and the north 
     rim was fuzzy and less bright than the east wall (this was hazy). P. 
     Moore observed that the crater was normal at 04:00UT. Cameron 2006

2018-May-01 UT 08:36-09:58 Ill=98% Torricelli_B observed by Cook_AC on 1985-12-28

     CCD images taken through Wratten 25 (red+near IR) and 87 
     (near IR only) filters. Between 00:02 and 00:25UT there
     was some slight evidence that a fade may have taken place
     however careful analysis by Cook casts doubt on this.
     Probably it was more related to a degradation in image 
     quality due to seeing than a true TLP. An ALPO/BAA
     weight of 1 has been assigned.

     Cleomedes Alpha 1993 Sep 03 UT2200-22:20 G. North (UK, 18.25" 
     reflector, x86 & x144) observed it to be a strikingly brilliant 
     'splodge' seen in the mostly shadow filled interior of 
     Cleomedes, and around this splodge was a faint halo extending 
     symetrically in an eastwards direction. The splodge was the 
     mountain Cleomedes Alpha. Strangely no shadow from the mountain 
     was seen to be cast onto the halo on the east. Observer alerted 
     other observers by phone, and upon returning to the scope found 
     that the splodge had faded in brightness and continued to fade 
     over the next hour as one would expect from a mountain at 
     sunset. Some heavy spurious colour was present. J. Cook & M. 
     Cook (Frimley, UK) observed at 22:20-22:25 and found the bright 
     splodge, but no halo. M. Cook re-observed later and confirmed 
     normal fading of splodge. Roscoe observed from 00:30UT next day, 
     but by that time Cleomedes Alpha had set and was no longer 
     visible in the shadow filled floor. S. Beaumont had observed 
     earlier at 20:00 but had recorded all as normal in Cleomedes.

2018-May-03 UT 07:46-09:36 Ill=90% Torricelli_B observed by Mobberley_M on 1985-12-29

     On 1985 Dec 29th at UT 23:23-23:58, M. Mobberley (Bury St. Edmunds, 
     Suffolk, UK, seeing II-III) made a video scan of the Moon. P.W. Foley 
     examined the tape and noted something that Mobberley had not seen 
     visually. Two scans of Totticelli B had taken place, one at 23:23 and 
     the other at 23:58UT. In the first a brilliant point appeared briefly, 
     on the western rim, positioned at 3o'clock. In the second video 
     sequence this brilliant spot was present continuously and wandered 
     along the rim. It was possible to monitor frequency of turbulence 
     present, this apparent movement did not ppear to conform, although 
     judgement here was extremelydifficult as the feature was at absolute 
     point of resolution, a little better than 0.5 mile. Also considered was 
     the implication of the equipment effect, this did not seem to fit 
     either as other nerby craters in the same configuration, 30% shadow 
     filled with sunlight on exterior of western walls. A point to watch for 
     in future. ALPO/BAA weight=3.

     On 1953 Sep 16 UT03:00 R.M. Lippert (San Diego, CA, USA, 20cm 
     Cassegrain reflector, x90)saw a bright magnitude 1 flash on the 
     Moon, that was probably on the east rim of Werner(?) crater. It 
     is unclear if the observer meant it was really magnitude 1, or 
     was what a magnitude 1 star would have looked like. The flash 
     was yellow-orange in colour. Observation described in the

2018-May-22 UT 20:19-22:02 Ill=58% Proclus observed by Darling_D on 1989-12-5

     On 1989 Dec 05 D. Darling of Sun Praire, WI, USA, saw two dark spots on 
     the SE floor of Proclus. The first dark spot was seen through  3" 
     refractor and then also through a 12.5" reflector (35x and 154x). 
     Seeing was S=10 and T=5. He noticed that at 23:00UT the wall spot was 
     less well defined. Darling also comments that he observed reflecting 
     glint, almost as if from a glass surface - he had not seen this effect 
     before. A telephone alert was issued and Caruso verified the spots. 
     Cameron comments that the spots were not shadows because the Sun was at 
     an altitude of 52 deg at Proclus at the time and she states that the 
     steepest slope ever mesured on the Moon was 52 deg and not inside 
     Proclus. Other observers observing were: Weier (6.5" refractor x284 and 
     S=3/10), Caruso (8" reflector x100), and Cameron. The Cameron 2006

     Picard, near to Picard crater. 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

2018-May-23 UT 00:48-01:23 Ill=59% Proclus observed by Mobberley_M on 1987-11-28

     On 1987 Nov 28 UT at 20:14 (possibly earlier)-20:44 M.Mobberley saw the 
     northern rim of Proclus very bright for first quarter. There were 
     streaks half way up the wall and these seemed to vary in brightness and 
     length in seconds. Seeing was at first suspected but became doubtful 
     over this being a cause. There was also another bright streak that 
     changed brightness over 5 minute intervals (Cameron says that this is 
     not atmospheric) Apparently video was taken and confirms the effects. A 
     sketch was also made. M. Cook detected a blink with coloured filters 
     i.e. being brighter in red light (Also apparently confirmed by 
     Louderback). Estimated the north west wall was x3 brighter than 
     Censorinus. Censorinus itself varied in brightness as measured using 
     CED devices. P. Foley decided that the north was was much brighter than 
     Proclus (beyond the limits of the scale. However both Moore and Mason 
     agreed that the north wall of Proclus was very bright but shimmering 
     around in the bad seeing. They did not see any bright spots either. 
     A.C. Cook (20:18-20:44UT) confirmed that the north wall of Proclus was 
     very bright. Towards the end of the observing period the north wall had 
     faded from this maximum brightness - Cameron suspects that this might 
     have been as a result of an eyepiece misting up. The TLP was also 
     observed by Foley (Maidstone, Kent, UK) and he reported: "Bright spot 
     on north wall, Moon blink reaction". A BAA Lunar Section report with 
     extracts from the 2006 Cameron catalog. Cameron 2006 catalog ID=315 and

     On 1987 Nov 28 M. Cook (Frimley, UK) found Censorinus varied in 
     brightness as measured using CED devices. P. Foley decided that the 
     north was was much brighter than Proclus (beyond the limits of the 
     scale). However both Moore and Mason agreed that the north wall of 
     Proclus was very bright but shimmering around in the bad seeing. They 
     did not see any bright spots either. A.C. Cook (20:18-20:44UT) 
     confirmed that the north wall of Proclus was very bright. Towards the

     On 1981 May 12 UT 22:00? M.C. Cook (Frimley, UK and using a 12" 
     reflector), noticed that Censorinus was very bright, fuzzy and 
     occasionally brighter than Proclus. However both Foley (Kent, UK) and 
     Amery (Reading, UK) using a C.E.D. found that Proclus was brighter than 
     Censorinus as it had been during April and May 1981. However Chapman

     refractor x36 and x90, and then a 12.5" reflector at x64, S=7/10 and T=
     4, saw dark spots in Proclus (not as dark as those from 5th Dec 1989). 
     Two telescopes were used and the bigger of these revealed some shading 
     on the floor of Proclus approximately a third as intense as he had seen 
     the previous night. A sketch was made. The TLP finished by 22:34UT. 
     Cameron comments that the dark patches could not be due to shadow as 
     the altitude of the Sun was too high at proclus. The Cameron 2006

     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

     Williams of the UK, on 1892 Aug 23 at Moon's age 10.0 days, noticed a 
     spot now rated at +1.5 (in brightness) that had been seen on the 21st 
     Aug, near Picard. Williams comments that this is the only obsewrvation 
     that departs "much" from the curve of diurnal brightness. The spot was 
     descibed as "nearly as large as Picard and nearly half as bright. 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

2018-May-25 UT 00:03-02:00 Ill=79% Plato observed by Marshall_KP on 1984-2-12

     The UT given in the Cameron 2006 extension catalog are: 20:58, 23:25-
     02:20 and 01:40-04:00, however it is not clerr what UT applies to which 
     of the observers or the two features reported as having TLP on that 
     night. On 1984 Feb 12-13 Marshall (South Anerica, seeing=III-II) saw 
     initially no craterlets in Plato, despite the Moon being at a high 
     altitude. At 01:45UT the northwest corner of Plato was red. Again no 
     other craterlets showed. He found the surrounding wall to be too bright 
     and this was confirmed by Crater Extenction Device readings and had 
     problems focussing on the crater. By 02:00-02:50UT he noticed 
     variability in the visibility of the craterlets. By 03:48UT the central 
     craterlet was much brighter than before and the crater doublet had 
     brightened but the southern craterlet was still invisible. Cameron 
     comments that Marshall was a very experienced observer. A. Cook (of 
     Frimley, UK) obtained a photodiode line scan image of Plato. The 
     brightness of the north west wall was brighter than the bright area on 
     the west wall. Marshall and Mosely both saw a dark area on the floor of 
     Plato close to the south wall (from clock position of 11 o'clock. There 
     was a prominent white spot on the floor and the central craterlet was 
     seen, but only under good conditions. Mosely does not discuss the west 
     and north west wall brughtnesses that were seen earlier by Cook and 
     Marshall. Cameron 2006 catalog extension TLP ID=240 and weight=2.

     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

     than blue, but Cobra Head was bright in blue. No other region was 
     abnormal.


2018-May-28 UT 00:54-02:48 Ill=97% Aristarchus observed by Louderback_D on 1980-4-28

     On 1980 Apr 28, Louderback (South Bend, WA, USA using a 8" reflector 
     and a 2.5" refractor) observed a very bright reg region on top of the 
     south west rim of Aristarchus crater. This was on the same side as the 
     ray system between Aristarchus and Herodotus. Louderback noticed some 
     chromatic aberation - blue where he had seen the red patch before.
     Louderback suspects chromatic aberation was the cause although did not 
     see red in that region ever again. "Patch was between his observation 
     points A and C. Point C was 5 points brighter in the red filter than in 
     the blue." A sketch was made. Cameron suspects that the TLP was real.

2018-May-28 UT 01:45-02:12 Ill=97% 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

     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.

2018-May-30 UT 01:29-03:26 Ill=100% 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

2018-May-30 UT 02:39-04:31 Ill=100% 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-May-30 UT 02:39-04:31 Ill=100% 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

     it Aristarchus that was varying, or Proclus?


2018-May-30 UT 03:02-04:54 Ill=100% 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.

     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-May-31 UT 07:59-11:50 Ill=97% 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.

     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
