     brighter than the walls of nearby craters. Cameron comments that Foley 
     says that this is normal and agrees. Cameron 2006 Catalog Extension ID=
     433 and weight=1. ALPO/BAA weight=1.


2021-Apr-02 UT 09:19-10:32 Ill=72% Plato observed by Foley_PW on 1975-6-28

     Plato 1975 Jun 28/29 UT 23:00-01:20. Foley (Wilmington, UK, 12" 
     reflector, seeing, III, good clarity transparency). At 23:00, 
     00:30, and 01:15 blue was seen on the inner wall:floor southern 
     boundary, and red on the corresponding northern floor:wall 
     boundary. However by 01:20, blue was now on the S-NW floor:wall 
     boundary, and red on the NE-SE floor:wall boundary. Atmospheric 
     spectral dispersion existed in many regions, but did not change 
     like the colours in Plato. Similar appearance craters such as 
     Grimaldi, Schickard, and Riccioli, were checked for a similar 
     change in colour, but no change was noticed in these. ALPO/BAA

2021-Apr-17 UT 01:40-02:55 Ill=20% Mare_Nubium observed by Cook_AC on 1986-3-15

     On 1986 Mar 15 UT 19:51-19:55 A. Cook (Frimley, UK, Naked Eye 
     and 12" reflector, x60, seeing IV, transparancy poor) 
     observed a naked eye flash at 19:50.5 UT in the Mare Nubium 
     area. The flash was white in colour and lasted not longer 
     than 0.5 sec and was about magnitude 2 at most in brightness. 
     There was no rise or fade associated with this flash. Upon 
     checking the area with the telescope, the observer reproted 
     seeing a faint fuzzy small patch that came and went over 
     several seconds in the same general area - but this may have 
     been due to the seeing conditions and/or glare from the 
     bright side of the Moon. The patch area was about the same 
     size as Aristarchus, i.e. approx 40 km across. Note however 
     that observing conditons were too poor that night to see 
     Aristarchus. At later observing sessions from  20:30UT 
     onwards, the patch was not seen. The ALPO/BAA weight=3.

     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 
     catalog ID=385 and the weight=0. The ALPO/BAA weight=1.

2021-Apr-18 UT 00:21-01:55 Ill=28% Aristarchus observed by Cook_JD on 1981-3-11

     A faint white pinpoint flash seen and also in the same position
     a whitish glow around the crater. No futher flashes seen after the
     first one. From UT2117-2130 the glow was still visible but faded
     making it more difficult to locate. When Foley observed he found 
     Aristarchus not very visible in Earthshine, despite Plato, Grimaldi,
     and several other features being visible. Both observers used
     12" reflectors. Cameron's 2006 catalog Extension ID=124 and 
     weight=0. ALPO/BAA weight=3.

2021-Apr-18 UT 03:08-03:50 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.

     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 
     "Observations and Comments" column in the December, 1953

2021-Apr-20 UT 00:23-01:16 Ill=47% 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 
     catalog extesnion ID was 382 and the weight=1. ALPO/BAA weight=3.

     Williams of the UK, on 1882 Aug 21 at 19:30UT (Moon's age 7.9 
     days) noticed a spot at least half as bright, and as large as 
     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 
     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.

2021-Apr-20 UT 04:37-05:29 Ill=49% 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 
     weight=4 (or 5?). ALPO/BAA weight=3. Apart from Louderback, all 
     observers were based in the UK and had a vatiety of telescopes and 
     observings conditions.

     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

     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.

     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

2021-Apr-21 UT 04:22-06:13 Ill=59% 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

     25cm reflector, x250 & x380, seeing good but with some cloud)
     The interior W. wall of this crater (on the lip) appeared 
     hazy - difficulkt to bring detail into focus. Neighbouring 
     craters/detail were sharp. Details in the crater wall interior 
     were starting to become visible as time went on, but it had

2021-Apr-22 UT 00:25-04:04 Ill=68% 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

     using a 7.5" refractor noticed that the center of Plato was 
     bright and opaque and the observer thought it was similar in 
     appearance to Linne. A sketch was made and two other observers

     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.

     25. The illuminated west crater wall stood out brilliantly in blue 
     light, much more so than in white light. This was true also of

     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

     Blanco, J. Vidal, of Gijon, Spain (3" refractor x72)
     noticed an unfamiliar very bright center near to Encke. 
     Cameron suspects that this was Encke B crater
     on the basis that it is a prominent small crater
     near to Encke. Cameron 2006 catalog extension ID=410

     Daniell 1979 Jul 06 UT 21:15-22:30 Crick (Belgium, 6" 
     reflector, Seeing=II and transparency=good.) noticed 
     obscuration on a bright spot on the south east wall. This spot 
     was quite prominent through a red Wratten 25 filter. The floor 
     was very dark. Other craters were checked and were normal. A 
     sketch was supplied and the position was the same as in other 
     earlier reports. Cameron 2006 catalog extension ID=60 and

     On 1977 May 30 at 21:04-02:13UT J.H.-Robinson noted a loss of 
     detail inside Gassendi, however he did not regard this as a 
     TLP. The effect was also seen by P.W. Foley. Cameron 2006

2021-Apr-25 UT 01:06-03:02 Ill=94% Vallis_Schroteri observed by Darling_D on 1991-8-23

     Flashing spot at end of SV fluctuated. Herzog, Darling &
     Weier confirmed spot but not fluctuation. Spot brighter in red
     than blue, but Cobra Head was bright in blue. No other region was 
     abnormal.


2021-Apr-25 UT 01:14-02:49 Ill=94% Aristarchus observed by Amery_GW on 1978-4-20

     Amery (Reading, England) saw blue in Aristarchus but a photograph did 
     not show the colour. Foley thinks this was spurious colour. Cameron

2021-Apr-25 UT 01:14-02:49 Ill=94% Promontorium_Laplace observed by Foley_PW on 1978-4-20

     Peter Foley observed a tiny yellow-brown region close
     to the tip of the cape, north east of the precipitous west
     edge, in the face of the north facing slope. The area
     concerned was diffuse and varied in density despite
     the surroundings not varying. Foley notcied no colour
     elsewhere on the Moon, though Amery thought that he saw
     some in Aristarchus, but Foley thinks this was spurious.

2021-Apr-25 UT 04:39-06:35 Ill=94% 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

     effusion of  smoke effect, which lasted about a minute, seen. 
     It appeared like the fluttering of a bird and passed over the 
     Moon before it evaporated, and must have been foreshortened,

     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

2021-Apr-25 UT 06:03-07:26 Ill=95% 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.

2021-Apr-27 UT 05:40-06:39 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.

     ceased due to being clouded out. ALPO/BAA weight=1.


2021-Apr-29 UT 07:06-08:21 Ill=93% Unknown observed by Cragg on 1965-5-18

     On 1965 May 18 at UT 03:00-03:30 Cragg (Mt Wilson?, CA, USA, 6" 
     refractor?) observed a TLP (no feature nor description given in 
     the Cameron 1978 catalog) on the Moon. The Cameron 1978 catalog ID=877 
     and weight=4. The ALPO/BAA weight=1.


2021-Apr-29 UT 07:49-07:56 Ill=93% Mare_Crisium observed by Wildey on 1962-7-19

     Mare Crisium 1962 Jul 19 UTC 09:48 Observed by Wildey & Pohn (Mt 
     Wilson, CA, USA, 60" reflector + Photometer) "Photometric meas. showed 
     change in brightness from Vmag=3.46 to V=3.07, where av. mag. for that 
     age=3.26, or a brightening of .58 mag." NASA catalog weight=5 (very 
     high). NASA catalog ID #763.


2021-Apr-29 UT 08:11-09:56 Ill=93% Aristarchus observed by Pedler_J on 1990-1-13

     On 1990 Jan 13 at UT 22:15-23:05 J. Pedler (Bristol, UK, seeing=III and 
     transparency=excellent, no spurious colour) detected a blue region on 
     the north of Aristarchus, varying in sharpness/diffuseness. The crater 
     rim in this region could not be descerned. Eleswhere the crater rim was 
     normal as too were other features. When a Moon blink device was used, 
     no colour blink was detected, however through the blue filter the 
     suspected area was bright and the crater rim indistinct. Whereas 
     through the red filter the area looked perfectly normal. At 22:30UT the 
     effect had vanished and everywhere was normal. The Cameron 2006 catalog 
     ID=388 and the weight=5. The ALPO/BAA weight=3.
