On 1972 Feb 23 at UT0010-0035 Fornarucci (Garfield, NJ, USA, 6" reflector, x250, seeing=fair and transparency=3.5). Shading usually visible west of it was not seen. Cameon comments that the albedo must have been at 5, where normally it is 4.5 and the nearby plain is 5). Cameron 1978 catalog ID=1322 and weight=2. ALPO/BAA weight=2.
Alphonsus 1990 Feb 03 UT 18:00-18:23 Observed by A.C. Cook (Frimley, UK, CCD video camera, seeing III-IV). At 18:06 W and SE dark floor patches, equally dark, but at 18:10 and 18:23 the W dark patch was the darker of the two?. Between 18:06 and 18:23 and a bright patch to the north of the central peak brightned slightly wrt the its surroundings. However seeing conditions worsened as the observing session progressed, and in view of this the ALPO/BAA weight=1.
Fracastorius 1975 Apr 19 UT 19:47, 20:40, 20:45 Observed by Robinson (Teignmouth, UK, 26cm reflector) "Fracastorius had a blink - it was bright in red and darker in blue at these three times, and probably in between. This was possibly natural surface colour being detected?". ALPO/BAA weight=1.
Mare Crisium 1975 Apr 19 UT 19:47-20:37 Observed by Robinson (Teignmouth, UK, 26cm reflector) "Mare Crisium N. end of floor - blink (red and blue filters) in patches, bright in red. Blink stops at 20:37". ALPO/BAA weight=1.
Alphonsus 1990 Feb 03 UTC 20:05-21:22 Observed by Brook (Plymouth, UK, 10" reflector) "Brightness variance noted". The Cameron 2006 catalog does not have an entry for this observation. The ALPO/BAA weight=2.
On 1975 Apr 19 UT 21:09 P. Foley (Kent, UK), detected blue in Plato on east. Fiton at UT20:45 found blue along the south wall at the east (IAU?) end, which was very bright white. Blueness extended towards the large landslip at the east of the formation. Immediately north of the landslip, where the bright wall curves first westwards, then again northwards, red could be faintly detected, folloowed by a very faint blue. All other parts of the formation were normal. Examination with a Moon blink device revealed no colour blink. J-H Robinson also found blue, with red on the west wall (exterior?). By 21:30UT Fitton found Plato to be normal and so was Proclus, though he did find Epigenes (bright cresecent of east wall only) slightly blue to the N.W and red to the S.E. Mare Crisium was normal. Prominent spurious colour seen on Venus, but it was low in the sky, with blue to the north and red to the south. However J.H. Reading, managed to see the north east floor blurred and slightly blue from 22:45-23:00UT. These reports are BAA observation. The ALPO/BAA weight=2.
At 03:00UT(?) Evrard et al from the western US(?) saw somewhere a reddish glow, followed by black obscuration. The date in the Middlehurst catalog is 18/1/65, but there may have been a descrepency between local time date and UT date? Cameron 1978 catalog TLP No=916 and weight=3.
On 1980 Jan 26 at UT21:35-22:25 Blair (Refrewshire, Scotland, 10" reflector, 83-276x, seeing=III-IV and transparency poor) discovered a bright spot on the north rim and through filters it "flashed" green, red and blue. Clouds interupted observing, but when they cleared the effect was still present. Other craters did not show this effect. Cameron catalog ID=83 and weight=4.
On 1993 Jan 02 at UT 17:42 A. Dollfus (Meudon, France, 1m aperture telescope used) detected evidence for a dust cloud in Langrenous crater using CCD polarimetry. The ALPO/BAA weight=4.

On 1987 Oct 03 at UT 01:0?0-02:00 R. Manske (Brooklyn, WI, USA, 8" reflector, x226) observed sunlight glinting of the walls in spectacular display of colours. White (even gold) was seen at the centre, and blue on the top most part of the rim. The white (or gold) band was thin in comparison to other bands. The observer suspects that this effect was terrestrial atmosphere related. Cameron 2006 catalog ID=307 and weight= 0. ALPO/BAA weight=1.

On 1991 Jan 26 at UT 23:38-23:50 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x159 and 3" refractor x90, seeing 5/10, transparency 3/6) found that Aristarchus was brighter through a red filter than through a blue filter on its western wall. He checked Aristarchus in two telecopes and obtained the same result. The Cameron 2006 catalog ID=419 and the weight=4. The ALPO/BAA weight=3.
On 2013 Apr 22 UT 01:39-02:37 P. Zeller (Indianapollis, USA, 10" f/4 reflector, x200, seeing 6, Transparency 3 - scattered cirrus) observed visually (depicted in sketch) the two closely spaced NW wall dark bands) to have a rusty-red hue. The colour of these bands did not change over the period of the observing session. Images were taken, but resolution and image S/N is not sufficient to resolve separate bands here, or to detect colour. The ALPO/BAA weight=1.
On 1987 Oct 04 at UT 02:20 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x170, S=8, VG, T=5) obtained the brightest measurement he had ever recorded on the northern rim of Proclus.

On 1981 Aug 11 at UT21:05-21:36 G. North (England, seeing=poor) detected, in green light, a darkening on the floor of Plato. This effect was not seen elsewhere. J-H Robinson (Teighmouth, Devon, UK) detected on the SSE rim (inner and beyond) a triangle that appeared hazy in a wide range of filters at 21:05UT. However at 21:36UT it was only hazy in green and blue light. No similar effect was seen elsewhere. The Cameron 2006 catalog ID=150 and weight=5. The ALPO/BAA weight=3.
On 2017 Feb 08 UT 01:45 A.Martini Jr (10" Schmidt-Cassegrain with ASI 120 MC camera +IR filter, Gain 40, Gamma 36, exposure 0.003 sec) saw on a computer monitor screen a flash to far to the west of Herodotus and Aristarchus at the location 54.53W, 23.5N. It had a duration of 0.5 sec and on a brightness scale of 0 = night side of the Moon to 10 = Aristarchus, ranked 7. Unfortunately they were not recording at the time. As there was no confirmation observation and it could be a cosmic ray air shower detection, the ALPO/BAA weight=1
In 1934 Feb 25 at UT 18:30 Rawstron (USA?, 4" refractor, x250, S=6/12) observed in Pico B: "A large patch of haze appeared & drifted off across the mare in same direction as haze from Pico (white patch).

Gassendi. 2023 May 02 UT 01:35-02:23. J. Albert (Lake Worth, FL, USA - ALPO. 8” SCT via a 9mm ortho eyepiece. Transparency magnitude 3 and seeing was 7/10) checked the crater without filters as well as comparing with W25 red and W44A blue filters using 226x. He saw no color on the SW part of the crater floor or on the NW wall. Using the filters, however, he did note that the high peak on the S wall was brighter in blue than red. He tried this filter blink a number of times because he had never seen this before in Gassendi, but the result was the same each time. A colour image was taken earlier at 01:21UT but shows not colour on S wall as it was saturated. ALPO/BAA weight=2.
On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector, x300) using an English Moonblink device found colour on the south west part of the floor. Note that for the times given by Cameron, the Moon was below the horizon from California - so possibly these are local times and these times need to be correctly converted into UT? The Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.
Gassindi 1966 Oct 25 UTC 22:30-23:10 Observed by Moore and Moseley (Armagh, Northern Ireland, 10" refractor) and Sartory (England, 8.5" ? reflector) "2 faint blinks (Eng.) on NW (IAU ?) wall. (Indep. confirm.?). NASA catalog weight=5. NASA catalog ID #987. ALPO/BAA weight=4.

NE of Philolaus 1948 May 20 UT 22:00-22:15 Observed by Baum (Chester, UK, 4.5" refractor) A distinct reddish tint suddenly appeared to the NE of the crater, and persisted for 15 min, before rapidly fading away. NASA catalog weight=3. NASA catalog ID #505. ALPO/BAA weight=3.
Moon 1967 Apr 22 UT 02:30 Observed by Dunlap et al. (Corralitos Observatory, Organ Pass, NM, USA, 24" reflector) "UV excess as in # 1029. Gradient was 10# at term. to 25-30$ at subsolar pt. (153 deg long)." NASA catalog weight=5 (very high). NASA catalog ID #1031.
On 1982 Dec 27 at UT 23:00 M. Price (Camberley, Surrey, UK, Seeing=III and transparency=good) observed that Piazzi-Smyth was brighter than Mon Piton at 23:00. Photographic atlas was checked to verify that this was abnormal. The Cameron 2006 catalog ID=193 and weight=4. The ALPO/BAA weight=2.
On 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st 7:24PM PST) saw a naked eye flash on the Moon. The observers were glancing up at the Moon in daylight when they saw a bright white flash (observer and his wife together) in the upper/mid Mare Serenitatis region, west of the crater Posidonius. "Larger than how Venus appears". "It was a quick flash like white, intense lightning. I'm not sure how to report degrees of arc but if the face we see is 900, and we start from the east then the flash occurred about 225 arc seconds to the west. This was observed by the naked eye, with clear skies between us and the moon." The observers checked for signs of aircraft vapour trails but could not see any. There is a possibility that it could have been sun glint from an Iridium satellite, but this needs to be checked out and usually these last longer than the observed effect. It would be useful to obtain whole Moon images under the same illunination and libration so that we can judge this observation properly. The ALPO/BAA weight=4.
Herodotus 1965 Jun 11 UTC 21:35-21:40 Observed by Porta, Garau (Mallorca, Baleares, 4" refractor x250) "Red glow in crater at 2140, then clouds stopped obs. After clouds, floor was abnormal rose color" NASA catalog weight=5. NASA catalog ID #879. ALPO/BAA weight=4.
On 1978 Mar 21 at UT 20:57 an Unknown observer observed a TLP in Aristarchus crater. The details for this report are still being looked up in the archives. In view of the uncertain details this TLP has been given an ALPO/BAA weight of 1.
Aristarchus 1982 Jul 03/04 UTC 20:55-01:08 Observed by Foley (Kent, UK, Seeing Antoniadi III) "Brightness variance" - CED 3.6-4.1-4.9. When the crater was dark it had a slate-blue-grey interior.

On 1982 Jul 03/04 at UT 20:45-01:08 J.D. Cook (Frimley, Surrey, UK) found the Mare Frogoris area, north of Plato was pink at 20:45UT. Saxton found flashes in Mare Frigoris and near thye Alps. The Cameron 2006 catalog ID=174 and the weight=5. The ALPO/BAA weight=2.
Interior craterlets could not be seen and some of the walls and exterior features were fuzzy. ALPO/BAA weight=1.
On 1965 Jun 12 at UT > 00:00 an unknown observer (Porta?) reported that the area of Herodotus and the Cobra Head expanded and the colour went to rose. The next night the floor was normal. In filters, phenomenon accentuated in orange. The cameron 1978 catalog ID=880 and weight=3. The ALPO/BAA weight=2.
S. of Aristarchus 1951 Sep 13 UTC 14:00? Observed by Osawa (Japan, 6" reflector) "Bownish-red color, blue on NW rim of A." NASA catalog weight=3 (average). NASA catalog ID #546.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi III seeing, 12.5" reflector) "Intensely bright craterlet south of central peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed the crater was highly luminous at 21:20, and surrounded by a blue halo that had a darker blue band within it. This craterlet faded over time, and by 21:20 Moore considered that it was no longer prominent, by 21:22 Foley confirmed the reduced brilliance, and by 21:30 Moore considered it to be perfectly normal. Moore considers the nimbus effect to be normal. The Cameron 2006 catalog ID= 306 and weight=5. The ALPO/BAA catalog weight=3.
On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a dusky dark gray area just north of Herodotus and just south of the Cobra Head. The interior shadow on the east of Herodotus by comparison wad black and distinct. No change was seen when viewed through a rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA) was observing at the same time but had better observing conditions and could see detail in this region, suggesting that it was not a TLP. There is no Cameron entry for this report. The ALPO/BAA weight=1.
Aristarchus and Cobra Head 1966 Oct 27 UTC 02:30-03:00 Observed by Delano (New Bedford, Massachusetts, USA, 12.5" reflector, x360) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moonblink). "C.p. of Aris. noticeably less bright thro blue filter but very bright thru red & no filter. Shadow of c.p. faint & grayish whereas wall shad. were normal black. (confirm. of Gordon, even tho 2h later?). Sketch. C.p. rated 10deg in red & no filter, & 8deg in blue. Other features rated same in all 3. Cobra Head had 2 red patches. Sketches.

On 1985 May 02 at UT 20:20-20:38 J.D. Cook (Frimley, UK) noted at 20:20 found the south rim (and just outside) to be blurred in appearence and there was also a hazy shadow inside the crater. M.C. Cook found a "break in clarity in break on S wall". Miles (UK) also found the south wall blurred in appearance and Foley (Kent, UK) noted that the area was featureless and the 2 craters positions at 1 o'clock high up on the inner wall were obscured", although just north of these was sharp detail. Foley also recorded that the shadow on the east wall was opaque"and that thye inside of Aristarchus was slate/blue in colour and dull, however by 20:28 the crater had brightened by 0.4 steps on Foley's CED device and the missing craterlets were visible again. Jean (Canada, 4" refractor) observed a rose colour intermittently (UT 1948- 20:58) - however Cameron suspects that this is chromatic aberation. The Cameron 2006 catalog ID=269 and the weight=5. The ALPO/BAA weight=3.

Phosphor. light distinguished easily against gray-green background of mare. Irreg., intermittent. Did not perceive them all dur. totality. Next day had impression that all of area was less clear & lightly veiled.". The Cameron 1978 catalog ID=561 and weight=3. The ALPO/BAA weight=2.
Aristarchus 1959 Mar 24 UT 04:35-05:15 Observed by Bartlett (Baltimore, MD, USA, 4" reflector x180, S=3, T=5) "Strong blue & blue-viol. gl. on E.wall, EWBS, SWBS with intermittent display.

On 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW, Australia, 8" reflector, x100, x160, S=III) observed a bright star-like point on the western (IAU) edge of Mare Tranquilitatis (x100) that appeared unlike any other crater and a check of the location revealed no suitably bright crater in that region (from a map?). Changed to a higher power (x160) and it was still there, but not as conspicuous. Observer thinks that this may have been due to the Moon's low altitiude (16 deg) and the seeing. At 18:35 he compared it to the brilliant crater Proclus and found the star-like point to be 75% of the brightness of Proclus. Ken Wallace (Australia) had been taking photos and observed the object at 17:37.5UT. The object gradually faded over the next 15 minutes and by 18:52UT could only be seen in averted vision at x100.

On 2000 Jan 21 UT04:40 G. Emersen (Golden, CO, USA, 30cm focal length lens with Wratten 25 ref filter) took 43 CCD images of the eclipse of the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively bright spot appeared in the southern part of Mare Fecunditatis. The spot looks sharper than the rest of the Moon and so might be a cosmic ray? CCD images taken from Washington D.C. by A.C. Cook at this time, do not show this spot, however exposures were at intervals of 0.25 sec and so might have missed this spot if it happened during image readout. The ALPO/BAA weight=1.

There was hardly any detail seen inside the crater. Herodotus could hardly be seen either and Schroter's valley was totally unrecognizable. A sketch was supplied. The Cameron 2006 catalog ID=223 and the weight=3.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3" refractor) observed that the south floor of Aristarchus was wellow - "almost gold, spilled over S wall on ray toward Herodotus". Cameron comments that Bartlett often reported a yellow floor but not a spill of the colour over to the external ray. Cameron also comments that Louderback's refractor would refract more in blue light than in yellow, therefore she did not think that it was due to chromatic aberation. The Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=2.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3" refractor) found that all of Mons Piton was "unusually dark". Points D, C (E and S resp), usually brightest points, but this time were not bright. "Whole mt was as dark as W wall usually is at this time. In violet filter Piton disappeared completely, but was a little brighter in red filter and points D & G showed. Color not seen by eye. No albedo measured. Suggests red event." Cameron rules out chromatic aberation from Louderback's refractor. The Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=1.
On 1985 May 09 at UT 22:50-03:10 P. Foley (Kent, UK) observed the whole of Aristarchus to be a strong violet color. No colour was seen elsewhere on the Moon. The Cameron 2006 catalog ID is 272 and the weight is 2. The ALPO/BAA weight is 2.
On 1985 May 09/10 at UT 22:50-03:10 P.W. Foley (Kent, UK) found that Torricelli B was very bright in Earthshine and was blue in colour. The Cameron 2006 catalog ID=272 and the weight=2. The ALPO/BAA weight=2.
On 1974 Jun 12 at UT0256 an unknown observer noted a dark blob on the northern edge of the floor of Pitatus crater.
Elger 1970 Aug 22 UTC 02:35-02:43 Observed by Merosi (Pecs?, Hungary, 6" reflector x150). "Brightening in dark beyond term., 3deg size, 1.5x size of Elger. Not variable for 5 min. but decreased & became in-vis. after 0243h. No high peaks there." NASA catalog weight=3 (average). NASa catalog ID #1275.
In 1835 Dec 22 at UT17:00-18:30 Piazzi-Smyth (Edinburgh, UK) at 18:30UT observed near Aristarchus a bright spot of magnitude 9-10 and at 17:00UT Baily (England) observed a star-like point, in Aristarchus. The Cameron 1978 catalog ID=113-114 and the weight=5. The ALPO/BAA weight=3.
On 1989 Feb 09 at UT 19:00 Ashton (Stafford, UK, seeing=V) observed a "green glow in the "peninsular region" of Cape La Place (south of poss. Helicon A?) and brown on the Earthlit limb. Foley (Kent, UK, 12" reflector) noticed a "pin point glow surrounded by blue-green halo" through a blue filter, but not seen through a red filter. He also suspected some brightness variations. He noted that Aristarchus was barely seen and Copernicus was only a faint smudge, presumably because of the bright limb? J. Cook (Frimley, UK) observed a white glow in the Cape region (made up of pin points?) - no other places had a similar effect. P. Moore (Selsey, UK, 12" reflector) reported that nothing unsual was to be seen anywhere on the Moon. M. Cook (Frimley, UK) found a "bright point source near the tip of LaPlace perhaps maupertius D (or LaPlace D?)." This was seen in a blue filter but not through a red filter - the limb was also seen as bright and the cape as a faint patch. Holmes (Lancashire, UK, 30"? reflector or refractor?) although commenting that Aristarchus was a bit dull, could not see the Sinus Iridum glow, North (UK) could only detect the vague presence of Earthshine throug his finder scope, but not in his telecope. The Cameron 2006 catalog ID=349 and the weight=2. The ALPO/BAA weight=3.
In 1909 May 23 at UT 18:00? an unknown English observer observed a bright spot east of Picard. The Cameron 1978 catalog ID=330 and the weight=1. The ALPO/BAA weight=1.
On 1989 Feb 10 at UT 19:00? D. Holmes and Wooler (Lancashire, UK) found area near Prinz to be bright, but so too was Aristarchus crater. The Cameron 2006 catalog ID=350 and weight=3. The ALPO/BAA weight=1.
On 1989 Feb 10 at UT 19:00? Edmonds (England) observed a "bright red coppery" colour in the northwestern part of Proclus crater. He checked and found that there was no colour elsewhere, though he still suspects that the effect was spurious colour. Cameron comments that usually blue is seen in the north and red in the south if due to spurious colour. The Cameron 2006 catalog ID=350 and the weight=3. The ALPO/BAA weight=1.
In 1900 Nov 26 at UT 19:00? an unknown observer (in Europe) observed a suspicious obscuring phenom on a dark plain (mare). The cameron 1978 catalog ID=307 and the weight=2. The ALPO/BAA weight=1.
1951 Mar 13 UT 01:35:50 L.T.Johnson (USA) observed a faint flash near W limb in earthshine - just S of Grimaldi. ALPO/BAA weight=1.
On 1985 Apr 25 at UT 21:34-22:04 H. Miles (England) observed Aristarchus within Earthshine. Foley (Kent, UK, 12" reflector) had observed it one hour prior to Miles and found it to be both dull and blue - with a bright patch west of the crater on Aristarchus Upsilon Mountain. At 21:45UT 6 star-like flashes seen on the floor. They occurred again a few minutes later and repeated at 22:04UT.By 21:45UT the bright patch had gone though. Smith (England) had also apparently seen the flashes and a further glow, albeit more north of the one seen by Foley. Miles confirmed Smith's glow north of Aristarchus. Peters did not see much, indeed found Aristarchus to be quite faint (2130-2141). The Cameron 2006 catalog ID=264 and the weight=3. The ALPO/BAA weight=2.
Curious lack of detail, but this may have been related to the seeing. Of greater interest though was a dark blue splodge where the crater should have been. Shadow seen through this splodge, but no crater rim seen.
Burg 2020 Dec 20 UT 19:00-20:08 (T.Smith, Codnor, UK, 16" Newtonian, seeing III-IV) observed visually that this crater was very red on its western floor and rim. A similar effect seen in Plinius, elsewhere on the Moon. No red was seen to the exterior of both craters. The redness on both of these craters had become diluted by 19:40. Also around this time, it was noted that Proclus had a slight redness to its western interior, though by no means as strong as in Burg and Plinius. A comparison with Censorinus revealed no redness to this crater. By 20:08 Burg was only showing a hint of red at times. ALPO/BAA weight=1.
Plinius 2020 Dec 20 UT 19:00-20:13 (T.Smith, Codnor, UK, 16" Newtonian, seeing III-IV) observed visually that this crater was very red on its western floor and rim. A similar effect seen in Burg, elsewhere on the Moon. The central peak of Plinius was very easy to see and also looked red in colour. No red was seen to the exterior of both craters. The redness on both of these craters had become diluted by 19:40. Also around his time, it was noted that Proclus had a slight redness to its western interior, though by no means as strong as in Burg and Plinius. A comparison with Censorinus revealed no redness to this crater. By 20:08 Plinius still had a slight red hue but Burg was only showing a hint of red at times. Observations ceased at 20:14 due to the Moon being hidden by an obstruction. ALPO/BAA weight=1.
Theophiuls 2020 Dec 20 UT 19:00 (T.Smith, Codnor, UK, 16" Newtonian, seeing III-IV) observed visually that the central peak of this crater appeared excessively/abnormally bright to his eyes. ALPO/BAA weight=1.
G Johnson of Swanton, MD, USA used a 2" refractor at f/12. Aristachus revealed as a red spot on a photo of the Moon. This was similar to another photo obtained on 1988 Apr 21st. Frame (with 3 exposures present)reveals a dim star like point near Campanus on exposure 1. Expsoure 2 shows it a little east on the Earth-lit part. Exposure 3 shows it off the south-east limb. Apparently 20 minutes later took 2 exposures and frame 18 was a double. The second exposure revealed an object farther from the limb but the first exposure does not show the object. The two high power exposures do not show it. Cameron could not see the spots that Johson describes on his slides, but did see several spots (defects?) on the 8 and 12 second exposures near Hevelius and also on the 20 second exposure near to Hecataeus only. BAA members observed star like flashes a few hours earlier - near Aristarchus. One BAA member, Madej, had seen a green glow in Arisarchus in two places in two eyepieces. Cameron 2006 Catalog extension ID=265 and weight=2.

Proclus 2020 Dec 20 UT 19:40 (T.Smith, Codnor, UK, 16" Newtonian, seeing III-IV) observed visually and noted that Proclus had a slight redness to its western interior, though by no means as strong as in Burg and Plinius which exhibited stronger red colours. A comparison with Censorinus revealed no redness to this crater. ALPO/BAA weight=1.
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. ALPO/BAA weight=1.
On 1989 Feb 11 at UT23:30-01:39 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x159, seeing=7/10) observed a linear east to west feature in Proclus. D. Weier (WI, USA, 11" reflector, x378) found the NNW part of the crater to be brighter than expected and confirmed the prescence of the east to west feature - this crossed the shadow on the east floor and over into Mare Crisium. R. Manske (WI, USA) detected another "streak" parallel to this. All observers suspect that the linear features were due to raised topography on the floor of Proclus - however Cameron comments that there does not seem to be any linear features on the floor of Proclus to cause these effects. The Cameron 2006 catalog ID=351 and the weight=5. The ALPO/BAA weight=2.

On 1895 Sep 25 at UT 20:00? Gaboreau (Paris, France) observed on the Moon s shaft of light (same observation as Cameron's TLP report #281 and further more it is on the same day and month as it was back in 1893. The Cameron 1978 catalog ID=286 and weight=0. The ALPO/BAA weight=1.
Mobberley and Foley note that Aristarchus was very prominent in Earhshine. Little other detail seen in Earthshine other than the limb. The Cameron 2006 extension catalog then says: "Confirm moving side to side. Saw bright blue spot in center" however it is unclear whether this refers to Aristarchus, or Torricelli-B - the latter was also undergoing a TLP at this time. Cameron 2006 extension catalog ID=267 and weight=5 (confirmed?).
On 1985 Apr 27 UT 22:00 M. Mobberley (Suffolk, UK) could not see much detail in Earthshine (apart from Aristarchus), except that there was a brightness on the western limb of the Moon. The Cameron 2006 catalog ID=267 and the weight=5. The ALPO/BAA weight=1.

On 1973 Dec 02 at UT 22:17:33 Barrett and Brick (New York, 3.5" Questar freflector) observed an occultation of Kappa Aquari, a wide double star, on the western limb. The star faded perceptably before disappearing. Cameron says that the fact that the star was a double was not an explanation - she says that there are many reports of similar fades for single stars.

Ptolemaeus 1978 Apr 15 UTC 21:54-22:20 Observed by A.Cook (Frimley, Surrey, UK, 12" reflector x240, S=IV (Antoniadi)) "Small triangular area on the NW floor of the crater, at the foot of the rim, was slightly brighter in blue light than in red (Moonblink used). Suspected this was due to the poor observing conditions. Certainly blink reaction was not unmistakable". ALPO/BAA weight=2.
On 1986 Nov 09 at UT 23:00 Quinn (Glebview, IL, USA, 8" reflector, x49- x305) found ïn the vicinity of an unnamed ridge points toward Pico- two bright points about 5 magnitudes brighter than any other part of the Moon. The Alpine valley points directly between these two points. "Came from apparently featureless area. Both points about the same size, but different shapes ~ width of alpine valley" The observer used 4 different eyepieces and the points were brightest in the lowest power. Other specks of light could be seen in the darkness wound the N point. The Cameron 2006 catalog ID=289 and the weight=3. The ALPO/BAA weight=2.
1996 Apr 27 UTC 02:26-03:14 Observed by Spellman (Los Angeles, CA, USA) " 02:26 U.T. Sunrise on Tycho 3/4 of the crater was in shadow, topmost section of the central peak was in sunlight. In white light brightness of the central peak rivaled the brightness of the Eastern (sunlit) wall. No change was detected in red light, however in blue light definite strong darkening was observed. Blink obtained when viewing thru 25A and 38 filters. At 2:52 U.T. in the poor to fair seeing the apparent size of the central peak in white and red light was the same, in blue light the central peak in white and red light was the same, in blue light the central peak size shrank to 1/2 white and red size (and brightness). Also appearing sharper. Comparison was made also with the central peak of Alphonsus, no changes were observed. The significant part of the observation was the relative brightness of the central peak to the sunlit rim in white and red light, they appeared almost identical with the crater rim, being just slightly brighter. In blue light the brightness of the central peak was reduced by at least half while the rim brightness was not, (relative to one another). I strongly believe that this was a real event. The shadow filled portion of Tycho was examined for any abnormalities but none were observed. Observations were ended shortly after 3:14 U.T. due to clouds. I also conducted about 20 Moon blink observations during this observing run and got the same strong reaction each time." ALPO/BAA weight=3.
