2020-May-01 UT 12:46-13:31 Ill=58% N_Pole observed by Harris on 1912-1-28

     North (?) (left) Cusp 1912 Jan 28 UT 00:00 (27th 20:00 L.T.) Observed 
     by Harris (Philadelphia? Pennsylvania?, naked eye?): Intensely black 
     curved object 400x240km, shaped like a "crow". Cameron 1978 weight=1 
     (very low) and ID=334. ALPO/BAA weight=1.


2020-May-01 UT 12:46-14:18 Ill=58% Eratosthenes observed by Hill_H on 1947-1-30

     Eratosthenes 1947 Jan 30 Mean Col. 16deg. Observed by Hill (UK) "Main 
     peak of massive central mountain group appeared to be in a shadowless 
     having regard to it's claimed height of 6,600 ft. The whole of the 
     floor to the west should have still been in darkness. Instead 
     immediately to the west was a dark (intensity 1.5-2) region extending 
     almost to the foot of the bright inner wall and very diffuse in 
     outline. The observation could not be followed through due to 
     increasing cloud, but on the following night all was normal."


2020-May-01 UT 12:46-13:25 Ill=58% Aristarchus observed by Loocks on 1969-11-18

     On 1969 Nov 18 at UT 04:22 Loocks (Valparaiso, Chile, 12" reflector) 
     observed a flash of light of magnitude 12. Cameron speculates a meteor 
     and mentions the apollo 12 watch. The Cameron 1978 catalog ID=1214 and 
     weight=1. The ALPO/BAA weight=1.


2020-May-01 UT 12:46-13:54 Ill=58% Eratosthenes observed by Longshaw_N on 2017-5-4

     Eratosthenes: On 2017 May 04 UT 21:50-22:10 N. Longshaw (BAA, 
     UK, 78mm APO refractor, x125 & x175, seeing II-III, 
     transparency Good). A brownish (orange) tint was seen on the 
     inner NW wall light terraces - this was immediately obvious 
     when first looking at the crater, but as time progressed the 
     effect became less bright. Other craters were checked for 
     similar coloured tints, but none were seen elsewhere on the 
     Moon. UAI observers in Italy (F. Taggogna & A. Tonon) had been 
     imaging the region in colour 17:57-21:47, but their images do 
     not show any colour on the inner NW rim terraces, the their 
     last image is 3 min before Longshaw saw the colour. The 
     ALPO/BAA weight=2.


2020-May-01 UT 13:58-15:24 Ill=58% Aristarchus observed by Tempel on 1886-6-10

     On 1886 Jun 10 at UT 21:00 (estimated) Tempel of Germany, saw a star-
     like light (Cameron comments that the reference in the Middlehurst 
     catalog is wrong). Cameron 1978 catalog ID= and weight=4. ALPO/BAA 
     weight=3.


2020-May-01 UT 15:24-17:09 Ill=58% 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 15:28-17:03 Ill=58% 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.

     On 1980 Apr 24 at 23:35UT Marco Petek (Porto Alegre, Brazil, 
     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 
     confirmed the appearance. Cameron mentions that Petek is an 
     experienced observer. Cameron 2006 catalog extension TLP ID=91 
     and weight=5. ALPO/BAA weight=3.


2020-May-02 UT 14:27-16:14 Ill=69% Cichus observed by Ryder_JW on 1975-9-15

     Cichus 1975 Sep 15 UT 11:15-11:30 G.Ryder (Corinda, Australia, 
     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 
     clouded over by 11:30. A Moon Blink was used but no colour was 
     detected. 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=70% 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 18:18-19:22 Ill=70% Atlas observed by Chernov on 1957-8-5

2020-May-02 UT 18:42-19:22 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 18:42-19:22 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. 
     ALPO/BAA weight=3.

     Bulialdus 1979 Aug 03 UT 21:36-21:48 Observed by Cook (Frimley, UK, 
     seeing III, Moonblink device) "Bullialdus eastern side of the crater 
     looked brighter in red i.e. rim and exterior, extending to the south 
     slightly and this reddish areas was slightly hazy. At 21:41 it clouded 
     over but at 21:47-21:48 it cleared briefly and effect was noted again. 
     Also Darney appeared very visible through the red filter. Probably 
     spurious colour as the Moon was -18 deg in declination and the whole 
     Moon had a slight brownish tinge" ALPO/BAA weight=1.


2020-May-03 UT 12:46-13:28 Ill=79% Darney observed by Cook_AC on 1979-8-3

     Darney observed by Cook (Frimley, UK, seeing III, Moonblink device) 
     See TLP report for Bullialdus (eastern side) concerning reddish
     areas. At 21:41 it clouded over but at 21:47-21:48 it 
     cleared briefly and the effect was noted on Bulialdus again.
     Also Darney appeared very visible through the red filter. 
     Probably both effects were spurious colour related as the Moon 
     was -18 deg in declination and the whole Moon had a slight 
     brownish tinge. An ALPO/BAA weight of 1 is assigned to this TLP."


2020-May-03 UT 12:46-13:20 Ill=79% Eimmart observed by Louderback_D on 1981-4-15

     On 1981 Apr 15 at UT06:27-06:40 D. Louderback (South Bend, WA, USA 
     using a 3" refractor x134 and S=4.5-5 and T=5-0) saw a bright spot on 
     the western wall of Eimmart (sketch supplied) have an unusual 
     brightening and shade. Variations occurred over 2-3 minute intervals. 
     Louderback commented that the spot looked like a flare with its apex 
     located at the crater wall and there was some blurring effect on the 
     spot - it decreased in size during the phenomenon. Seeing worsened 
     later. Apparently on the 18th and 19th of April everything was back to 
     normal. Cameron comments that there is no bright spot on the Moon at 
     this location. Lunar Orbiter IV plates 192-3.2 shows evening

     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 
     reference. All the above seems normal, apart from the floor
     being brighter in the green filter. Cameron 2006 extension

     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

     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 15:17-16:31 Ill=95% 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

2020-May-05 UT 16:00-17:56 Ill=95% 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.


2020-May-05 UT 16:32-17:19 Ill=95% 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

2020-May-05 UT 16:32-17:19 Ill=95% 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.

2020-May-05 UT 19:38-21:23 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 
     unusual when he started observing at UT 22:00. Cameron says 
     "Photos marked at location of phenomenon". Cameron 2006

2020-May-05 UT 19:43-21:04 Ill=96% 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.

     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,

2020-May-05 UT 20:44-21:52 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.

     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

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.

     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 
     weight=1.


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 
     weight was 4. ALPO/BAA weight=3.


2020-May-08 UT 15:27-16:23 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.


2020-May-08 UT 15:28-16:27 Ill=98% Aristarchus observed by Pasternak on 1973-10-12

2020-May-08 UT 17:12-18:45 Ill=97% Copernicus observed by Rawlings_G on 1978-4-23

     On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50) 
     observed a bright flash (~0.3 sec duration) near to Copernicus (20W, 
     9N) with rays to the south east whilst he looked through a finder 
     scope. Moore, who studied the drawing, suggests that the area of the 
     flash was near Copernicus. However Cameron says this cannot be the case 
     if the flash was in darkness as mentioned in the BAA Lunar Section 
     circular. She comments that it might have been a meteor? The Cameron 
     2005 catalog ID=28 and weight=1. The ALPO/BAA weight=1.

     South Pole 1997 Apr 10 UTC 20:45 Observed by Livesey (Scotland, 65x33, 
     Seeing Antioniadi II, Transparency : Thick Haze Alto Stratus, windy) 
     "Two bright spots seen - one on southern tip of crescent and 2nd way 
     over on the dark side of the S. limb. Earthshine seen, but no 
     features". Probably these are just peaks making it into sunlight -
     though one of them was of considerable distance from the tip of
     the cresecent (was this the peak of eternal light?). So therefore 
     the ALPO/BAA weight=1 i.e. it is worth checking out - however we 
     may not be able to tell for sure until the libration matches 
     up too.

     Earth, he said that he was dark adapted at the time and was unable to 
     say whether it was a cosmic ray or an impact flash. Cameron says that 
     there have been many similar reports in the past from Earth-based 
     observers e.g. TLP report No. 1167). The Cameron 1978 catalog ID=1352

     On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8" 
     reflector, x110 and x220) observed that Proclus and Piccolomini craters 
     both had a pink colour inside them. At a higher magnification of x220 
     Piccolomini was still pink and it was stronger on the central peak's 
     wesern side. The cameron 2006 catalog ID=407 and the weight=3. The 
     ALPO/BAA weight=1 as the Moon was not above the horizon at the date and UT given.

     reflector, x110, x220, seeing=good) observed that the north wall of 
     Proclus crater was the brightest part of the crater, indeed very 
     bright. Proclus and Picolomini had pink colours inside them. CED 
     brightness measurements were as follows: "Proc. at 100x 4.0, 4.0; at 
     200x 3.4, 3.4; Theop. 3.5, 3.9; 3.5; Herc. 2.5, 2.75; 3.5; Atlas 2.8,

     reflector, x110 and x220, seeing=good) observed that the west wall of 
     Theophilus crater was red (on terminator). However Posidonius was also 
     on the terminator and no colour was seen elsewhere along the 
     terminator, however Proclus and Piccolomini had pink interiors. At a 
     higher power of x220 a prismatic effect was seen on the terminator in 
     Theophilus and opther craters - "even on W rim of a crater due W of 
     Theoph.". CED measurements of Theophilus... 3.5, 3.9, 3.5. The Cameron 
     2006 catalog ID=407 and the weight=3. The ALPO/BAA weight=1
     because the Moon was below the horizon at this time.

2020-May-28 UT 15:14-16:25 Ill=33% Messier observed by Robinson_JH on 1981-2-10

     Messier 1981 Feb 10 UT 19:20-20:10 TLP discoevered by Hedley 
     Robinson (Devon, England) "Messier was brighter than Aristarchus 
     in both red and blue filters and also appeared indistinct, later 
     becoming invisible - lost in a bright streak. In comparison 
     Aristarchus was clear. Another observer, Amery confirmed that 
     Aristarchus was sharp in appearance but Messier certainly was 
     not. Cook likewiese found Messier not to be as sharp as Messier 
     A dueto a big shadow in Messier A. Pedler found that the sun 
     facing wall of Messier was OK but that the shadow was changing 
     from black to grey periodically at intervals of 2-3 minutes to a 
     few seconds. By contrast he found that Messier A remained quite 
     well defined. He tried red and blue filters but found no blink 
     effect. At 20:23UT Pedler found that the shadow had stabilized 
     to a shade of "mid grey" although remaining ill-defined. North 
     also found that Messier A was distinct but Messier itself was 
     ill-defined. Moore found the same thing but thinks that this is 
     normal for Messier under this illumination to appear indistinct. 
     More also saw the grey interior shadow. Price saw similar 
     appearance to Moore and suspected that this was normal for this 
     stage in illumination. Ratcliffe suspected everything normal - 
     just commenting that Messier was smaller and no detail in 
     comparison to Messier A. Madej and Taylor provided a sketch that 
     showed again a grey interior and merging with the east 
     wall/mare. Foley found Messier's pale grey interior to be un-
     focusable but in comparison Messier A was sharp. He says that he 
     would expect a grey interior and the east wall to merge with the 
     mare. However the complete loss of deatil and variability were 
     not normal. Cameron comments that the Kuiper atlas confirms the 
     fuzzy indistinct appearance of Messier and that a Lunar Orbiter 
     picture shows a grey shadow. The Cameron extended catalog 
     weight=5. The ALPO/BAA weight=2.

     6.5" reflector x200) "Great brilliance of the terraces in E(IAU?) wall 
     system(?) gets specular refl. (he gave 0820UT, but must have meant

2020-May-31 UT 12:50-14:22 Ill=66% 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.


2020-May-31 UT 12:50-14:22 Ill=66% 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 
     eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog 
     ID=408 and weight=0. The ALPO/BAA weight=1.

     NASA catalog ID #998.


2020-May-31 UT 16:34-17:34 Ill=67% Vitello observed by Unknown_Observer on 1960-8-1

     On 1960 Aug? 01 at UT 22:00? an unknown observer detected that Vitello 
     was illuminated -it should have been in shadow? Cameron says that if 
     several days before sunrise then the date could have been July through 
     to December, with August 1st most likely, and ancilary data is 
     therefore given for this date. The Cameron 1978 catalog ID=729 and 
     weight=1. The ALPO/BAA weight=1.

     On 1989 Jan 16 at UT 20:00 G. North (Herstmonceux, UK, 30" reflector) 
     observed Toricelli B to change in brightness and found colour in it. A 
     10 minute exposure spectrum was taken (Cameron does not have 
     information on whether anything unusual was recoeded) before clouds 
     obscured the Moon. Normally a 30 minute exposure would be needed. The 
     Cameron 2006 catalog ID=345 and the weight=3. The ALPO/BAA weight=3.
