On 1982 May 26 at UT 20:25-20:40 Kalauch (Berlin?, Germany, 9" refractor, x60, T=1(best) and scintilation=2) found Aristarhus to be "very visible" in Earthshine - which was very clear. At 20:25 UT Aristarchus was seen to blink irregularly and then it attained magnitude 7 (red). Telescopes and eyepieces were changed but did not effect the appearance. It disappered at 20:40UT. Cameron 2006 catalog ID=168 and weight=2. ALPO/BAA weight=2.
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 1965 Dec 27 at UT Bornhurst (Monterey Park, CA, USA, 10" reflector) and (Harris (Whittier? CA, USA, 19" reflector?) observed brightening of Aristarchus in Ashen light. Cameron says that this is an independent confirmation? The Cameron 1978 catalog ID=918 and weight=4. The ALPO/BAA weight=2.
Barker's Quadrangle (26W, 34S) 1949 Mar 03 UT 20:00 Observed by Moore (England, 12" reflector) "Whole area hazy. (in Capuanus? see Wilkins and Moore, The Moon, p124) (It may not be this identification as 3 of 4 obs. are in dark, some nr. FQ so doubtful it could be seen)." NASA catalog ID #516, weight=4. ALPO/BAA wight=2.
On 1983 Feb 15 at UT 18:00? G. Amery (Reading, UK) found that he could not see Aristarchus in Earthshine, despite less normally priminent features being clearly seen. This observation was confirmed. Other observers were: Moore, Cooks, and Foley. The Cameron 2006 catalog ID= 203 and weight=2. The ALPO/BAA weight=2.
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.
On 1990 Jan 01 at UT 17:29 H. Miles (Cornwall, UK) observed that Copernicus had a faint glow in it. The Cameron 2006 catalog ID=385 and the weight=0. ALPO/BAA weight=1.
On 1983 Feb 17 at 19:00?UT G. Amery (Reading, UK) noticed that Aristarchus was not visible in Earthshine, despite other less prominent features being seen. The observation was confirmed by other observers. The Cameron 2006 catalog extension ID=204 and the weight=2. The ALPo/BAA weight=2.
On 1983 Feb 17 at 19:00?UT G. Amery (Reading, UK) noticed that Messier was ill-defined. The Cameron 2006 catalog extension ID=204 and the weight=2. The 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.

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.

Moeller (Syracuse, NY, USA, using a Konica Minolta DIMAGE Z5 digital camera, f/7.1, 1/250 sec exposure, ISO-50, 69mm focal length, digital zoom x3) captured a hand held image of the Moon in daylight. On the SW limb of the dark side of the Moon a bright spot can be seen. This has a brightness comparable to that of Mare Serenitatis. There is also a fainter dark blurred marking further inside the dark side. ALPO/BAA weight=1.
On 1789 Sep 26 at UT04:25? Schroter (Lillienthal, Germany) noted a bright point 26" north of Aristarchus crater. Note that the year might have been 1788? The Cameron 1978 catalog ID=50 and the weight=3. The ALPO/BAA weight=3.
Schroter, from Lillenthal in Gemany, in 1789 (possibly it was 1788) Sep 26 UT 04:30 saw a small nebulous bright spot on the northern edge of Mare Crisium. Cameron 1978 catalog ID=50 and weight=3. ALPO/BAA weight=1.
On 1789 Sep 29 at UT04:25? Schroter (Lillienthal, Germany) noted 1'18.5" south east of plato was a whitish bright spot shining somewhat hazily, 4-5"in diameter and at 5th magnitude. He never saw this again. The spot became conspicuous at times and then disappeared. There was nothing else similar in Earthshine. Note that the year might have been 1788? The Cameron 1978 catalog ID=50 and the weight=3. The ALPO/BAA weight=3.
In 1948 Apr 15 at UT 20:00? Vince (England, UK) observed a bright spot, about magnitude 3, in Earthshine, about 30deg north of Grimaldi., on the west limb (90W, 25N). The Cameron 1978 catalog ID=503 and the weight=3. The ALPO/BAA weight=3.
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.
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. The Cameron 1978 catalog ID=1384 and weight=4. The ALPO/BAA weight=1.
2004 Nov 20 UT 02:34:03 R. Spellman (120mm F8.3 refractor at prime focus, PC23C CCTV camera, via a DVD recorder) recorded a flash of light. The ALPO/BAA weight=2.

Seemed to be 2 active volcanoes. Ridge was normal color. Spots were yellow or flame color. Never seen before in 40 yrs. of observing." NASA catalog weight=4 (high). NASA catalog ID #129. ALPO/BAA weight=3.
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. This report was submitted to the GLR group in Italy. 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.
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.
Proclus 1967 Apr 18 UTC 18:40-18:45 Observed by Farrant (Cambridge, England, 8" reflector x175) "Crater appeared quite dark, even bright ring was subdued & seemed thicker than normal. Drawing." NASA catalog weight=3 (average). NASA catalog ID #1028. ALPO/BAA weight=1.
On 1995 Sep 03 at UT19:40-20:15 P. Moore (Selsey, UK, 15" reflector at x400) observed that the floor of Plato was much darker than he would normally expect and futhermore no interior craterlets were seen. there was however a white patch that was barely visible at the location of the central craterlet should have been. G. North (UK) attempted to observe nut the Moon was too low and seeing terrible. F. Doherty reported Plato normal. Cameron 2006 catalog ID=475 and weight=3. ALPO/BAA weight=1.
Linne 1868 Jul 28 UT 20:00? Observed by Tacchini (Palermo, Italy) "Shadow not so marked-had a light penumbra, indicated a feeble cavity. Other craters had a black shad.

On 2010 Aug 19 at UT 00:50-01:02 J.Albert (Lakeworth, FL, USA, C11, Transparency 3, Seeing 7-8, 86F and very humid. Oberver checking out repeat illumination condition appearence for Tycho concerning LTP #468 in the 1978 Cameron catalog. Did not see the effect from the original TLP report, but did see, immediately at looking at Tycho a very faint hint of redness in a pencil thin arc (< 1/4 circumference of the rim) confined to the top of the rim of the well-lit north east wall. Coloured arc similar in thickness to Rupes Recta, but not as sharply defined. The outer (E) edge was perhaps sharper than the inner edge. The redness was more on the inside of the top of the rim. The outside of the rim was bright white. This effect was seen in three different eyepieces, at 311x, 224x and 400x. Checked for the effect on other craters nearby but could not see this effect anywhere else. The colour had dissapeared by 01:02UT. The fade took about 1-2 minutes. Observation of Tycho continued until 01:06UT, but all seemed normal. Quick checks were made again on Tycho periodically until 02:50UT but the colour was not seen again. ALPO/BAA weight=3.
Plato 1949 Mar 09 UT 02:00-03:00 E.J.Reese (6" reflector x240) and one hour later T.R.Hake (5" refractor x300) both unable to see any detail on the floor of Plato, despite both being able to see a "difficult to see" cleft near to the crater Connon. Reese was able to see detail under similar illumination back in 1948 and 1947 and saw the floor craterlets in Plato clearly then. ALPO/BAA weight=1.
On 1989 Feb 15 at UT 03:15-03:30 M. Dixon (Palenque Ruins, Mexico, 7x35 binouculars) observed a point of light that was very bright in or near Mare Humorum. It was visible for 5 minutes then vanished. The Cameron 2006 catalog ID=353 and weight=1. The ALPO/BAA weight=1.
On 1964 Feb 22 at UT 05:00 Harris (Whittier, CA, 19" reflector, x100) observed the appearance of a ring to the south east of Ross D. Cameron says that 7 persons have seen this over a 2.5 year period. The Cameron 1978 catalog ID=801 and weight=1. The ALPO/BAA weight=1.
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.
2004 Jan 02 UT 09:05 (approx) M. Collins (Palmeston North, New Zealand, ETX 90, seeing 3, clear) saw a possible(?) flash north of Carlini D at about 16W, 35N in adverted vision. It lasted only a split second. The ALPO/BAA weight=1.
M.C. Cook (Frimley, UK) got an abnormally low brightness reading for Proclus, despite nearby Censorinus being normal. Crater Extinction Device used. The Cameron 2006 Extension catalog ID was 163 and the weight was 3. The ALPO/BAA weight was 2 too.

No similar effect seen elsewhere. A.C. Cook (Frimley, UK) detected spurious colour on several craters, including Plato that night. Cameron 2006 Catalog Extension ID= 337 and weight=0. ALPO/BAA weight=1.
Arsyukhin and others (Moscow, USSR), with naked eye and binouculars saw three dark spots suddenly appear on Mare Crisium and disappear approximately 30 minutes later. Cameron 2006 catalog extension ID=145 and catalog weight=4. ALPO/BAA weight=2.
Arsyukhin and others (Moscow, USSR), with naked eye and binouculars saw TLP activity in Plato that Cameron thinks confirms what UK observers saw later. Cameron 2006 catalog extension ID=145 and catalog weight=4. ALPO/BAA weight=1.
Alphonsus 1966 Apr 01 UT(?) 03:00-03:20 Observed by Jenning, Harris (Coral Estates, CA, USA, 12" reflector) "Red patch from c.p. to W. wall (no confirm. from Corralitos obs. moon blink device & obs. at that time)" NASA catalog weight=3. NASA catalog ID #924. ALPO/BAA weight=2.
Agrippa and vicinity 1878 Dec 04 UT 20:00? Observed by Capron (France?) "Odd, misty look as if vapor were in or about them" NASA catalog weight=3 (average). NASA catalog ID #209.
On 1980 Jul 22 at UT20:08-21:50 G.North (Sussex, UK, 8" reflector, x144 and x207, seeing III-V and transparency fair) suspected an obscuration on the north and north west wall. The effect came and went. May have been due to seeing and image contrast? Cameron 2006 catalog ID=101 and weight=1. ALPO/BAA weight=1.
Plato 1982 Jun 02 UT 22:00. Mobberley could not see the central craterlet on the floor of Plato tonight. Foley notes that he could only just see the central craterlet on nights of 2-5th Jun and it was of reduced in brightness from normal. North reported that the floor seemed nearly black, but brighter in a green filter (x144 magnification used). All three observers compared the Plato area to other areas for reference. All the above seems normal, apart from the floor being brighter in the green filter. Cameron 2006 extension catalog ID 170 and weight=5. BAA/ALPO weight=2.
A blue tinge was seen inside and outside the crater perimeter. The surrounding halo lost brightness that was observed on 1993 Jan 29. Observed on Apr 19, 20 and 28th. Cameron 2006 extension catalog ID=213 and weight=5. ALPO/BAA weight=3.
On 1990 Jan 07 at UT 20:20-20:58 G.North (Herstmonceux, UK) thought that he detected dullness in Torricelli B crater - Cameron comments that this cannot be shadow). The Cameron 2006 catalog ID=386 and the weight=3. ALPO\/BAA weight=2.
Plato 1971 Oct 30 UT 19:35-20:55 E.Watkins (Braintree, UK, 4.5" reflector, x45,x150, x225), thought he saw a faint patch at 19:35 and it still was visible at 19:40. At 19:50-19:55 he saw what may have been the remainder. At 20:55 he noticed a shadow in the area. ALPO/BAA weight=1.
Plato 1906 Mar 06 UT 22:00? Observed by Fauth (Germany? 6" refractor) "Color (brightness?) greatly enhanced as it was to be on the next nite" NASA catalog weight=3 (average). NASA catalog ID #324.
Peice A (Swift=IAU name?) 1927 May 12 UT 22:03 Observed by Wilkins (England, 15" reflector) "Complete obscuration of crater. Saw no trace of it. It was vis. May 11 & faint on May 13. 3x in 1948 Moore saw whole area misty gray & devoid of detail, whereas surroundings were sharp & clear. Birt also found it invis. at times in late 1800's" NASA catalog weight=4. NASA catalog ID #394. ALPO/BAA weight=3.
Near Hyginus 1959 Sep 13 UT Observed by Bradford (S.Shields, England, 15"? reflector), Feist, Lovas (Hungary), Moore, Wilkins (Kent, England, 7" refractor, x500) "Obliterated by a hovering cloud (Feist disagrees).

The ALPO/BAA weight=1.
On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5" reflector, x159) observed an "anomalous black bar across Aris. Nearly digonal to terminator." The nearby crater Prinz had curious shadow patterns, perhaps related to the rising sun projecting shadows from the eastern rim and "reflected down"? "At 0224 W wall had a break in it & a diffuse glow where it should not be. Manske thinks it was Earthshine effect. At 0305 Weier saw Manske's bar - with diffused light and flicker like an aurora - like a gas with electric charge. At 0325 saw a strange glow in Aris. but may be due to atm. though thought it to be a LTP. Darling had never seen such effects before (flickering implies a medium in it)." The Cameron 2006 catalog ID=387 and the weight=3. The ALPO/BAA weight=3.
On 1933 oct 01 at UT 03:00 Rawstron (USA, 4" refractor, x330) observed the following in Mons Pico B: "Haze -- much narrower & elongated than on Sep. 1". The Cameron 1978 catalog ID=407 and weight=3. The ALPO/BAA weight=2.
Observed by Haas (Las Cruces, NM, USA) "Temporary greyness seen in interior shadow." ALPO/BAA weight=3.
On 1955 Oct 28 at UT00:00? Kozyrev (Crimea, Soviet Union, 50" reflector) detected in Aristarchus Fraunhofer lines in UV spectra that were much narrower than in the solar spectrum. This indicated luminescent glow which overlapped contour(?) lines. Greatest after Full Moon, but fluctuated monthly with no indication of solar activity effect. The Cameron 1978 catalog ID=621 and the weight=5. The ALPO/BAA weight=5.
On 1955 Oct 28 at UT 00:06 W. Taylor saw a naked eye flash on the Moon in the north east area, on the edge of Mare Vaporum. The flash was intense and radiated to a large area. The duration was 1/4 seconds.
Aristarchus 1981 Mar 17 UT 22:40-23:25 Observed by Moore (Selsey, England, 15" reflector, seeing III) "Aristarchus very bright according to Crater Extinction Device and a coloured blink detected" BAA Lunar Section TLP report. ALPO/BAA weight=1.
On 1965 May 12 at UT 22:20 H. Miles (UK) found a possible obscuration in Bailly crater. Most of the region was as sharp as normal, but the central area was greyish and blurred. Although the observer concerned considered themselves a non-experienced observer, another BAA Lunar Section observer saw the same effect. ALPO/BAA weight=2.
Aristarchus Area 2004 Nov 22 UT 04:58-05:49 Observed by Gray (Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5, x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red 25. The illuminated west crater wall stood out brilliantly in blue light, much more so than in white light. This was true also of Aristarchus. Red light did not increase contrasts in Herodotus any more than they were in white light. Shadows in Herodotus appeared as black as the night west of the terminator and remained that way throughout the observing period. No TLP seen in Herodotus tonight. A possible TLP was seen to the west of Herodotus near the terminus of Schroters Valley. It was noted at the beginning of the observing period that there were four very bright spots of light, one near the end of Schroters Valley, the other three grouped together a little farther north. Although not far from the terminator they were definitely east of it. It was noted that all of them nearly vanished in the Blue 38A filter while Aristarchus and the rim of Herodotus gleamed brilliantly. At 5:19UT it was noted that the most brilliant of the four lights, the one near the terminus of Schroters Valley, had faded almost to invisibility in white light. When first seen it had been brighter than Aristarchus. It remained very dim after this through the remainder of the observing period, and was unchanged at 7:35-7:49UT when I again examined the area. The other three bright spots remained brilliant and unchanged."
Aristarchus 1973 Aug 10 UTC 20:14 observed by Baumeister (48.63N, 9.25E, 110mm reflector, T=2, S=2) "Orange to red colours at the crater floor disappeared until 21:04" - Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61. ALPO/BAA weight=2.
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 and weight=2. ALPO/BAA weight=1.
Plato 1973 Aug 10 UT 22:45 observed by Robinson (Devon, UK). Observer noticed that the lighter areas on the floor were more distinct in red than in the blue filter. ALPO/BAA weight=1.
Proclus 1972 Dec 17 UTC 18:30 Observed by Farrant (Cambridge, England, 8.5" reflector) "Crater appeared very bright (Apollo 17 Watch)." NASA catalog weight=2 (low). NASA catalog ID #1359.
Herodotus 1966 Nov 24 UT 21:50 H.Hill (UK, 7.25" reflector, x240), seeing 4-6/10, transparancy 4/5) sketched a central white diffuse patch inside the floor of the crater, with a size of about 1/7th the diameter of the crater. The eastern edge of the white patch was encroached by the shadow of the eastern rim. ALPO/BAA weight=3.
Proclus 1976 Sep 06 UT 02:00 Observed by Bartlett (Baltimore, MD, USA, 4.5" reflector 45-300x, S=3, T=5) "Nothing vis. on floor of 2deg brightness. Usually floor ray & Proc. A are vis. at this col. & c.p. is 5 deg bright. (must have been 2 deg tonite)." NASA catalog weight=4. NASA catalog ID #1450.
All observers saw a blue tinge seen inside and outside the crater. Marshall observed a bright spot in the middle of the crater floor and thought perhaps that it was a central peak. No central peak can be found on Lunar Orbiter images. Cameron 2006 Catalog extension ID=214 and weight=5. ALPO/BAA weight=4.
Cobra Head, Aristarchus 1964 Feb 25 UT 02:37-02:38, 02:39-02:42 Observed by Budine (Binghamton, New York, USA, 4" refractor, x250, S=6, T=4) "Red flashes" NASA catalog weight=3 (average). NASA catalog ID # 802.
In 1949 Nov 03 UT 01:06 J.Bartlett (3.5" refractor, x100) noted that the floor of Herodotus was very dark, the east wall was very bright, and the floor contained a central bright peak. The BAA/ALPO weight=3.
Crick of Belgium 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 weight=3. ALPO/BAA weight=3. 6" reflector used. Seeing=II and transparency=good.
M. Cook of Frimley, "NE ray distinct & also floor E of it, not distinct as on Dec 13 & Jan 11, while March 10, 11 & 12 seen by Price, North, Peters, Foley & M Cook, where rim was clear and sharp." - quote from the 2006 Cameron Catalog extyension - TLP ID=297 and weight=5. Cameron gives the observers confirming this TLP as: M. Cook, G. North and Davies.. ALPO/BAA weight=3.
Aristillus 1972 Dec 17 UTC 21:50-22:20 observed by Berger (51.5N, 9E, 60mm refractor, T=2, S=3) "Diffuse bright cloud in the NE corner of the crater" - Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53- 61.
Kepler 1954 Nov 07 UTC 23:20 Observed by Lugo (Caracus, Venezula) "Luminous pts. (MBMW say "bright pt.; just outside E.wall). NASA catalog weight=3 (average). NASA catalog ID #580.
Aristarchus 1919 Jun 10 UT 19:00-19:30 Observed by Lapshin (Russia) a "Greenish-yellow light shone from inside the crater for 1/2 hr. after which it returned to normal. Violet tint on W. bank & surrounding area & the dark color of the saddle & dark spot were distinct. Term. slightly E. of Herodotus. (Ast. E)=IAU W." NASA catalog weight=3. NASA catalog ID #372. ALPO/BAA weight=3.
Plato 1906 Mar 07 UT 22:00? Observed by Fauth (Germany? 6" refractor) "Color (brightness?) greatly enhanced as on the previous nite" NASA catalog weight=3 (average). NASA catalog ID #324.
On 1980 Jul 24 at UT22:10-22:55 P. Moore (Selsey, UK, 15" reflector, x360 and x400) found an area just south east of the central peak (and upto the wall) to be quite dark in blue light, but normal brightness in red light or in white light. All other features were normal colour- wise. At 22:55UT Tycho was normal again. Cameron 2006 catalog ID=103 and weight=4. ALPO/BAA weight=3.
Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore (Sussex, UK) saw the wall as normal. However Cameron points out that Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely (Covington, UK) at 22:10 UT noticed a brightening on the East wall and at 01:10-01:25 UT suspected that the interior had a weak yellow-green cast to it. Cook (Frimley, UK) states that orange colour was within the interior crater, but green beyond the east rim at the 9 O'Clock and the south east corner to floor blue/mauvre beyond the northern rim NW/WSW. Foley sstates that orange and blue/mauvre might be spurious colour, but green one cannot get this way. Cameon suggests chromatic aberatons as a possibility but thinks that the observers concerned were experienced enough to recognize this if it were the cause. Cameron 2006 catalog extension ID=239 and weight=0. Moore used a 15?" refletor and Foley used a 12" refletor. Mosely experienced II seeing and good transparency. Cook had III seeing and also good transparency. P. Grego made an observation this night too. The ALPO/BAA weight=2.
Amery (Reading, England) saw blue in Aristarchus but a photograph did not show the colour. Foley thinks this was spurious colour. Cameron 2006 extension catalog ID=27. ALPO/BAA weight=1.
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. Cameron 2006 catalog extension ID=27 and weight=5. ALPO/BAA weight=3.
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.
Aristarchus-Cobra Head, 1967 Nov 15 UT 05:40-06:00 Observed by Cross, Tombaugh (Las Cruces, NM, 12" reflector x800) and Harris (Tucson, AZ), and Dunlap (Organ Pass, NM, 24" reflector with Moonblink). "Obs. reddish color N. & E. of Aris. & more intense color nr. E.(IAU?) rim of Cobra Head. Red color nr.C.H. confirmed by Tombaugh. Obtained 10 photos between 0543-0549h in 3 spectral bands (blue, yellow, red, & integ. light). No change dur. obs. per. but spot got smaller at moments of good seeing. Isodensitometry of photos. At Corralitos 0152-0155 on 24- in image intensifier & filter sys. photoos at 0320-0330h. Harris at Tucson got spectra. Neither of latter 2 show anything unusual. Its edges were nebulous even at best seeing. Size @ that of Cobra's Head." NASA catalog weight=5 (very good). NASA catalog ID #1053.
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 extension catalog ID=37 and weight=5. ALPO/BAA weight=3.
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 extended catalogID=63 and weight=1. ALPO/BAA weight=1.
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. Cameron 2006 catalog ID=281 and weight=4. ALPO/BAA weight=3.
Plato 1873 Apr 10 UTC 21:00? Observed by Schmidt (Athens, Greece, 6" refractor) "Under high sun, 2 faint clouds in E. part of crater."
Aristarchus 1975 Sep 18 UT 21:00? Observed by Foley (Kent, England, 12" reflector) "Deep blue-viol. spot in NW (IAU?) interior corner." NASA catalog weight=3. NASA catalog ID #1414. ALPO/BAA weight=3.
Aristarchus 1989 Oct 13 UTC 21:00 Observed by Cook (Frimley, Surrey, UK, 20cm reflector (visual and video)) "Aristarchus had what appeared to be a outline of a ghost crater on it's eastern side - quite large and bright". Cameron 2006 extended catalog TLP ID No=378 and weight=5. ALPO/BAA weight=3.
Gassendi 1976 Oct 04 UT 21:30 P. Moore (Selsey, UK, x400, seeing poor) observed redness in the c.p. area. The ALPO/BAA weight=1.
Plato 1981 Jun 15 UTC 21:30 Observed by Amery (Reading, England, 25cm reflector, seeing Antoniadi IV-V) At the 4 O'Clock position on the North West corner?, there was a dark smudge which reached from the floor across and over the wall and onto the terrain outside the crater. Foley, alerted by Amery, saw a dark show-like patch in the crater's north west corner, again lying across the rim. 2006 Cameron catalog extension ID=148 and weight=4. Foley used a 12" reflector and seeing was III-V. ALPO/BAA weight=3.
Plato 1870 May 13 UT 22:00? Observed by Pratt (---), Elger (Liverpool, England), (Gledhill (Brighton, England) "Extraordinary display of lights. 27 seen by Pratt, 28 by Elger, only 4 by Gledhill. (independ. confirm. ?" NASA catalog weight=5 (very good) NASA catalog ID #168. A bit more of a detailed report is as follows: "Upon the 13th of May, 1870, there was an "extraordinary display," according to Birt: 27 lights were seen by Pratt, and 28 by Elger, but only 4 by Gledhill, in Brighton. Atmospheric conditions may have made this difference, or the lights may have run up and down a scale from 4 to 28. As to independence of sunlight, Pratt says (Rept. B.A., 1871-88), at to this display, that only the fixed, charted points so shone, and that other parts of the crater were not illuminated, as they would have been to an incidence common throughout.(30) In Pratt's opinion, and, I think, in the opinion of the other observers, these lights were volcanic." ALPO/BAA weight=4.
On 1892 May 10th at 19:00UT? Pickering, based at Arequipa. Peru, using a 12" reflector, saw varitions in vapor col. Drawings were made. Time calculated from the given colongitude. Cameron 1978 catalog ID= and weight=3. ALPO/BAA weight=2.
Plato 1937 Jul 22 UT 06:20 Observed by Haas (Alliance, Ohio, USA, 12" reflector?) "Floor distinctly greenish, but was gray on June 23, 1937 at 0430 & col.84 (normal?)" NASA catalog weight=4 (high). NASA catalog ID #421. ALPO/BAA weight=3.
On 1982 Jun 05 at 22:00? UT, Chapman (UK, using a 12" reflector), again using a x2 yellow filter, noticed that the central craterlet detectabilty changed such that sometimes it was visible and sometimes not. Foley (Kent, UK)noticed that the central craterlet could only just be seen between June 2 to June 5 and was much less discernable than during the previous lunation. No CED brightness measurements made. The floor of Plato was noted to be very dark though. Cameron 2006 catalog ID=172 and weight=4. ALPO/BAA weight=2.
Aristarchus 1965 May 15 UTC 01:40-02:15 Observed by Weresuik, McClench, Johnson (Pt. Tobacco, MD, USA, 16" reflector x240, S=F, T=G) and Delano (Massachusetts, USA, 12" reflector). "Crater had color(red?) detected by Trident MB & photos were obtained. There were pulsations. Delano saw E. wall of crater unusually bright (confirm. if at same time)." NASA catalog weight=5 (very good). NASA catalog ID #876.
Bailly 1974 Oct 29 22:00-23:00 Observed by Lord (St Annes-on- Sea, UK), 25cm reflector, x125 & x400,seeing III, transparency 5/5. South west floor was darker in a blue filter than in other filters. Observer thought this was due to a natural green colour here. Had seen this on 3 other occasions under early morning illumination. ALPO/BAA weight=1,
Eratosthenes 1976 Sep 08 UTC 04:29 Observed by Bartlett (Baltimore, MD, USA, 4.5" reflector 45-225x, S=5-4, T=5) "Psuedo-shadow X3 was present but X disappeared from wall(same intensity?) which was rated 4 deg. Disappearance of X so unexpected that he examined inner S wall very carefully & was certain it was free from psuedo-shad. Had vanished within 24h. Other pseudo-shadows showed no change. X reappeared next nite. (X must have been 4deg; &this is much higher than any other meas.). Variability of wall shadows may habe been what Pickering saw, suggests Bartlett." Cameron 1978 TLP catalog weight=4 and catalog ID 1452. ALPO/BAA weight=2.
Madler 1940 Sep 16 UT 02:10 Observed by Haas (New Mexico? USA, 12" reflector?) "Bright spot on S. rim was I=5.8 comp. with 8.9 on Aug 17 (see #470)." NASA catalog weight=4. NASA catalog ID # 473. ALPO/BAA weight=2.
On 1964 Jan 28 at 21:00? Scarfe (UK) obtained spactra showing luminescence? The Cameron 1978 catalog ID=798 and weight=5. The ALPO/BAA weight=3.
Plato 1973 Aug 13 UT 22:25-22:35 observed by Pedler (Devon, UK). Observer noticed a slight blink on a lighter patch on the floor just beneath the south(?) rim using Moon blink filters. ALPO/BAA weight=1.
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 catalog ID=380 and the observation weight=3. The ALPO/BAA weight=2.
Herodotus 1971 Dec 02 UT 20:40 Observed by Kilburn (Manchester, UK, 8" refractor, x130, Transparency very good with a thin mist, seeing excellent, x130). Bright point (considerably brighter than its surroundings) was seen on the SE of the illuminated floor of Herodotus in white light. It was quite close to the crater rim. The spot had no colour. ALPO/BAA weight=2.
Aristarchus 1967 Dec 16 UTC 22:00? Observed by Farrant (Cambridge, England, 8" reflector) "Crater took on an unusual appearance on inner NE (ast. ?) wall. Showed a very pale blue & the opposite wall a pale red color seen in no other features. Lasted only 10m & survived a change of eyepieces." Seeing=I (Antoniadi). NASA catalof weight=3 (average). NASA catalog ID #1056.
On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor, seeing=II) found that the inner bands of Aristarchus were hard to see, this was odd because the seeing conditions were good and he usually sees them? However he did not believe that there was any obscuration going on. The Cameron 2006 catalog ID=37 and weight=0. The ALPO/BAA weight=1.
On 1893 Apr 01 at UT 22:00 deMoraes of the Azores, Portugal, saw a shaft of light projecting from the Moon. Cameron 1978 catalog ID=280 and weight=0. ALPO/BAA weight=1.
Manillus 1955 Aug 03 UTC 21:00 Observed by Firsoff (Sommerset, England, 6.5" reflector, x200) "Maniluus very bright in all colors, especially blue, extraordinarily so" NASA catalog weight=4 (good). NASA catalog ID #602.
Timocharis 1955 Aug 03 UTC 21:00 Observed by Firsoff (Sommerset, England, 6.5" reflector, x200) "Crater was bright in blue, seemed large & diffused." NASA catalog weight=4 (good). NASA catalog ID #602.
On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a 6" reflector, Seing = 6/10) noticed blue on the north east corner of Aristarchus and an orange glow on the south east wall. They detected no movement or change in brightness. The observer used both eyes, to make sure it was not an eye defect, and three filters: red Wratten 25, blue Wratten 82 and Violet Wratten 47. Porter found that the colours faded for a duration of 5 minutes and then returned. Their right eye gave a good view and using their left eye they suspected that it was 0.5 steps brighter than the remainder of the crater. The suspected colour remained visible, even under moments of good seeing conditions. The colour eventually faded over time and was eventually gone. Porter reportd seein gcolour here on the following night. Apparently other bright spots showed no colour. Fitton suggests that the filters used confirm that the south east wass was definitely red in colour. The Cameron 2006 catalog ID=37 and the weight=0. ALPO/BAA weight=1.
Aristarchus 1973 Nov 10 UTC 20:00? Observed by Coates (England, 8" reflector x200, Moon at gigh altitude above horizon). "Attracted to crater because of an orange hue extending towards Herod.

On 1992 Jul 16 at UT 03:32-09:31 D. Louderback (South Bend, WA, USA, 3" refractor, x134) detected yellow on the southern rim of Aristarchus, and the colour looked "darker" through a yellow filter and the region was "duller" than normal. The region was 1 intesnsity step brighter on the 2nd measurement, "on all points in it". The comet tail-like ray had 3 sections and was "mottled" in appearance. Finally the Cobra Head region had possible variations in brightness. The cameron 2006 catalog ID=451 and the weight=3. The ALPO/BAA weight=2.

On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300) noticed a lack of detail in the Cape Agarum area - he would normally have expected to have seen some craterlets. However he would not rate this observation much because the seeing was only III and he does not think that it was an obscuration. However just in case he wanted to record this report in the archives. ALPO/BAA weight=1.
Proclus 1973 Nov 11 UT 20:40-23:05 Observed by Savill (Cambridge, England, 12" refractor, x100?), Young (Yorks, England), Pedler (Bristol, England, 6" reflector?), Livesey (Scotland). "At 100x showed a bright spot in S.part of crater. At 300x was vis. but power too high. In 8-in refr. at 170x, at 2055h 2 spots present. Confirmed by Young. Seeing was improving. At 2104h in 12-in refr. at 260x the lower spot seemed distinctly enlarged & vaporous. Decided it was due to poor seeing. Later the 2 spots were better defined & separated but lower moved away fr. larger one & they seemed more separated than earlier. Obs. ended at 2305h when they decided it was not an LTP. but was 2 craters instead of humps. There were neg. repts. from others at the same time. (there are no craters in Proclus)." NASA catalog weight=2. NASA catalog ID # 1382. ALPO/BAA weight=1.

Aristarchus 1968 Dec 07 UT 07:00? observed by Corralitos Observatory (Organ Pass, NM, USA, 24" reflector+Moon Blink) "Bluing around 3 craters, strongest at Aris. Lasted several days. Photos show 30% more intensity in blue filter than in red or neutral. Moon's declination northerly. Obs. think it was due to atm. effects" NASA catalog weight=5 (very high). NASA catalog ID #1105.
On 1968 Dec 07 at UT 07:00? Corralitos Observatory (Organ Pass, NM, USA, 24" reflector and Moon Blink device) observed a bluing around three craters, one of which was Kepler. This effect lasted several days. Photographs were taken that show30% more intensity in the blue filter than in red or neutral. The Moon's decination was northerly. The observers suspect that it was an atmospheric efect and not a TLP. The Cameron 1978 catalog ID=1105 and the weight=5. The ALPO/BAA weight=3.
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.

There were two white patches of apron material near to the crater Herodotus that were 50% of the brightness of the southern half of Aristarchus. Furthermore the southern half of Aristarchus had a circle - "dull patch on inner S wall with a bright point shining through it. (Bartlett's EWBS?)". The Cameron 2006 catalog ID=389 and the weight=4.
