2020-May-01 UT 16:29-17:48 Ill=59% Censorinus observed by Cook_MC on 1981-5-12

     On 1981 May 12 UT 22:45-2325 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 obtained the 
     reverse of this. Cameron 2006 extension catalog ID=138 and 
     weught=3. ALPO/BAA weight=1.

2020-May-01 UT 16:29-17:09 Ill=59% Proclus observed by Darling_D on 1989-12-6

     On 1989 Dec 06 at 23:09-23:34UT D. Darling of Sun Praire, WI, USA (3" 
     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 
     extension catalog ID=383 and the weight=0. The ALPO/BAA weight=2.

2020-May-01 UT 18:07-19:43 Ill=60% Plato observed by Carle on 1952-11-26

     In 1952 Nov 26 at UT 01:00? Carle (USa, 8" reflector, x700, 
     seeing = excellent) observed the following in Plato: "Sketch 
     shows  8 spots -- 5 craters showed interior shad., 1 
     completely  filled, but no others seen despite several hrs. of 
     study. Spots that should have been seen were missing. poor 
     seeing converts floor into shimmering shapeless blob. Has 
     observed it under good seeing & seen nothing on fl. as others 
     have noted". The Cameron 1978 catalog ID=555 and weight=3. The

2020-May-01 UT 18:39-20:19 Ill=60% Montes_Carpatus observed by McCorkle on 1955-8-27

     On 1955 Aug 27 at UT 01:51 McCorkle (Memphis, Tennessee, USA, 6.5" 
     reflector, x200) observed a 2nd magnitude bright flare on the dark side 
     of the Moon. This remained steady, fading slightly before abruptly 
     disappearing. Cameron suggests that this might have been a meteor. The 
     Cameron 1978 catalog ID=604 and weight=0. The ALPO/BAA weight=1.


2020-May-01 UT 19:20-21:14 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.

2020-May-01 UT 20:26-22:06 Ill=61% Plato observed by King_N on 1983-4-21

     On 1983 Apr 21 at UT 21:55-22:05 N. King (Winersh, Berkshire, 
     UK, using a 150cm f/8 reflector, with seeing I and 
     transparency good, little spurious colour, just a little in 
     Plato). Although observing since 21:25UT the observer noticed  
     a just detectable faint green colour just after the dark shade 
     around the inner eastern crater rim. The effect faded and by 
     22:05UT had completely gone. This report is not in the Cameron 
     2006 catalog. It is a BAA report. The ALPO/BAA weight=2.


2020-May-01 UT 21:08-22:06 Ill=61% 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.

     On 1983 Feb 21 at 20:00UT P.W. Foley (Maidstone, Kent, UK, 12" 
     reflector) noticed a deep steel blue colour inside Toricelli B with a 
     lighter colour about 10-15 miles outside. Foley came to the conclusion 
     that this was too visible for its size. Cameron 2006 Catalog extension 
     ID=206 and weight=3. ALPO/BAA weight=2.


2020-May-01 UT 21:55-22:06 Ill=61% 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.

2020-May-02 UT 16:29-17:49 Ill=70% Carlini_D observed by Collins_M on 2004-1-2

     2004 Jan 02 UT 09:05 (approx) M. Collins (Palmeston North, New 
     Zealand, ETX 90, seeing 3, clear) saw a possible(?) flash north 
     of Carlini D at about 16W, 35N in adverted vision. It lasted 
     only a split second. The ALPO/BAA weight=1.


2020-May-02 UT 16:30-17:41 Ill=70% Mare_Imbrium observed by Caruso_J on 1979-8-3

     A region of the Mare Imbrium was extremely bright, giving
     a reading of 8 out of 10 on the Elger scale. Cameron notes
     that from photos of the Full Moon, the area appears to
     normally be the brightness of Archimedes floor i.e. 3.5 out
     of 10 on the Elger scale. Atmospheric seeing was excellent
     and the observer could see a lot of fine detail with their
     2.4" and 3" refractors. Cameron 2006 catalog extension ID=62
     and weight=3.


2020-May-02 UT 17:42-19:01 Ill=71% Curtis observed by Williams_AS on 1882-8-23

     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 
     illumination angles and is one of three outlying brightness points 
     spotted on a graph by Willaims. The ALPO/BAA weight=3.

2020-May-02 UT 18:42-20:20 Ill=71% Moltke 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 clear 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) 
     noticed that Moltke was very bright with a fuzzy violet hue - he had 
     never seen it like this before. Cameron 2006 catalog extension TLP ID=
     240 and weight=2. ALPO/BAA weight=3.


2020-May-02 UT 18:42-20:20 Ill=71% 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.

     Gassendi 1977 May 28/29 UT 20:45-21:15 Observed by D. Sims 
     (Dawlish, Devon, UK) saw a hazy area on the south east floor 
     that was normal in red and white light but darker in blue. 
     This was partly confirmed by J-H Robinson (Devon, England, 10" 
     reflector) 21:24-23:12 who saw the south east floor of 
     Gassendi to have a loss of detail - but no colour seen, 
     although at 21:57-21:58 it was slightly brighter in red than 
     in blue briefly. P. Doherty (22:45-23:15) did not see anything

     Plato 1982 Jun 02 UT 22:00. Mobberley could not see the 
     central craterlet on the floor of Plato tonight. Foley notes 
     that he could only just see the central craterlet on nights of 
     2-5th Jun and it was of reduced in brightness from normal. 
     North reported that the floor seemed nearly black, but 
     brighter in a green filter (x144 magnification used). All 
     three observers compared the Plato area to other areas for

     On 1982 Apr 04 at UT 23:30-00:25 P. Madej (Huddersfield, UK, 7cm 
     refractor & 16cm reflector) noticed the TLP in his refractor 
     first of all at x25. So stepped up the magnification to x111 and 
     found the crater brightness not what he was expecting. He tried 
     different filters but found no difference in brightness. With 
     the 16cm reflector however some changes in brightness were 
     dected. The crater has a very pale yellow colour and it was 
     slightly darker than Lacus Somniorum. P. Foley tried to confirm 
     at 00:09 but the crater looked normal then. The Cameron 2006

     (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."

2020-May-05 UT 19:31-22:26 Ill=96% 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

     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.

     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.

     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

2020-May-07 UT 20:12-21:52 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
     but did suspect that the interior of Aristarchus was a bit unusual. 
     Don Spain did not see anything unsual at all. Cameron 2006 extended

     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

     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

2020-May-07 UT 22:03-23:03 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

     On 1987 Mar 09 at UT20:00 M. Mobberley (Sussex, UK) obtained some video

     some one who analyzed the tape). The Cameron 2006 catalog ID=300 and 
     the weight=5. ALPO/BAA=1.
