     12.5" reflector, x80, S=II=I and transparency=good-poor) 
     observed Aristarchus to be glowing in the dark at magnitude 3 
     and at its maximum it was dazzling. The glow vanished at 
     02:57UT. The Cameron 2006 catalog ID=54 and weight=1. The

     reflector - seeing=poor and transparency=poor) P.W. Foley of ---- saw 
     faintish yellow-brown streaks in Aristarchus. Apparently these had been 
     seen the previous night, but were much fainter tonight. Bartlett had 
     previously seen this effect on the southern floor of the crater 
     according to Cameron. The Cameron 2006 catalog extension ID No. is 133

2019-Apr-12 UT 17:54-19:43 Ill=50% Curtis observed by Williams_AS on 1882-8-21

     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.

2019-Apr-12 UT 17:54-18:27 Ill=50% Werner observed by Lippert_RM on 1953-9-16

     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 
     Strolling Astronomer (Vol. 7, No. 12), on page 170. The ALPO/BAA 
     weight=3.


2019-Apr-12 UT 17:54-19:16 Ill=50% 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.

2019-Apr-12 UT 22:06-23:02 Ill=51% 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.


2019-Apr-12 UT 22:36-23:02 Ill=51% Censorinus observed by Cook_MC on 1987-11-28

     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 
     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=2. Apart from Louderback, all observers were based in 
     the UK and had a vatiety of telescopes and observings conditions.


2019-Apr-13 UT 17:56-18:29 Ill=61% Aristarchus observed by Tempel on 1886-6-10

     On 1886 Jun 10 at UT 21:00 (estimated) Tempel of Germany, saw a star-

2019-Apr-13 UT 18:07-20:03 Ill=61% Proclus observed by Cook_MC on 1981-5-12

     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 
     obtained the reverse of this. Cameron 2006 extension catalog ID=138 and 
     weught=3. ALPO/BAA weight=2.


2019-Apr-13 UT 18:10-20:02 Ill=61% Proclus observed by Darling_D on 1989-12-6

     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.


2019-Apr-13 UT 18:52-20:48 Ill=61% Censorinus observed by Cook_MC on 1981-5-12

     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.


2019-Apr-13 UT 22:44-23:29 Ill=63% 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.

     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 cery, just detactable 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.

2019-Apr-14 UT 20:14-22:11 Ill=73% 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.

2019-Apr-14 UT 21:24-23:19 Ill=73% 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.

     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

     than the nearby mare and no detail could be seen on the floor or the 
     eastern wall - the later was obscured. At 23:40UT some dimming was 
     still present on the north east wall and still no detail on the floor 
     of Plato. Cook noticed that the eastern floor close to the wall was 
     misty and also noted no detail on the floor. Amery though noted that 
     all parts of the floor were sharp although some darkening was visible 
     in the north west and a hint of obscurtion. The east wall though was 
     quite sharp. Mosely could see the central craterlet but from 8-6 
     o'clock tricky to define (Foley says that this effect has been seen at 
     this colongitude before). Streak ray across the floor of Plato seen 
     (North) - filter measurements made. Cameron 2006 catalog extension ID=

2019-Apr-17 UT 18:03-19:47 Ill=96% Aristarchus observed by Louderback_D on 1988-1-2

     On 1988 Jan 02 at 06:41-07:08 UT D. Louderback (South Bend, WA, USA, 
     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 
     weight=4. ALPO/BAA weight=3.


2019-Apr-17 UT 18:03-18:48 Ill=96% Promontorium_Agarum observed by Louderback_D on 1988-1-2

     On 1988 Jan 02 at 05:57-06:13 UT D. Louderback (South Bend, WA, USA, 
     using a 8" reflector, seeing 4 out of 10) observed that points B and D 
     on Cape Agarum faded suddenly from 7.0 to 6.4 (B) and 6.0 (D). However 
     these returned to their normal levels at 06:13 UT. Cameron 2006

2019-Apr-17 UT 19:47-19:58 Ill=96% 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.


2019-Apr-17 UT 22:20-00:16 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.

2019-Apr-17 UT 23:42-01:24 Ill=97% 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.

2019-Apr-19 UT 23:06-00:53 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 
     when it dimmed suddenly over a period of about a minute or so. No 
     colour effects seen. ALPO/BAA weight=2.

2019-Apr-20 UT 00:32-02:04 Ill=99% 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.
