On 1969 Jul 20 at UT 0845 McIntosh (Auckland, New Zealand, 14" reflector) saw Aristarchus crater to be brighter in red light. This was during the Apollo 11 watch. The Cameron 1978 catalog ID=1173 and weight=3. The ALPO/BAA weight=3.
On 1974 Feb Weith-Knudson (Copenhagen, Denmark, 12" refrlector, x72) observed a magnitude 7.7 flash (comparison between SAO093043=mag 7,8 and SAO093052 mag=7.5 that happened to lie in the field of view at the time) in Earthshine. The observer speculates whether this was a lunar meteorite impact or a reflection from an artificial satellite (or indeed as Cameron suggests from an Earth meteor?). The cameron 1978 catalog ID=1388 and weight=0. The ALPO/BAA weight=1.
M. Price of Camberley, UK noticed that an area in relation to the central area of the floor could not be resolved. Averted vision was used, but this did not help to resolve detail. The crater was close to the terminator and was in general sharply in focus apart from the suspect area. No spurious colour seen. Sketch supplied.P. Foley wonders if the effect was due to the resolution limit of Price's scope? Cameron 2006 extension catalog ID=78 and weight=2. ALPO/BAA weight=2. 6" reflector x64 and x120. Seeing=III-IV and Transparency=good.
On 1975 Mar 18 at UT17:30 M.Kidger (Winterbourne Down, Bristol, UK, 60mm refractor, x36, very good conditions with a very sharp image and the sky was almost perfectly clear apart from a very few small clouds). In Mare Crisium it was observed that only a ray of Proclus could be seen to cross the floor - normally there are at least four craters visible inside mare Crisium on good nights and at least one being visible under bad conditions. So despite it being very clear and the image quality being good, the observer found it odd that no craters were visible on the floor of mare Crisium. This is a BAA Lunar Section report. The ALPO/BAA weight=2.
Observations made by Challis of Cambridge, and N. Pogson of Hartwell, both of the UK. Before the occultation, Saturn's rings were distorted. A dark border was seen around the Moon. Just before re-appearance a sea green colour was noticed. Cameron 2006 catalog extension ID=5 and weight=2-5. ALPO/BAA weight=1.
In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of twilight (Cameron says also seen by Gruithuisen, Henry and others at times). Webb gives a low weight to his own observation, saying "for want of better optical means". The Cameron 1978 catalog ID=130 and weight=1. The ALPO/BAA weight=1.
Sabine 1967 Sep 11 UT 00:32,00:45 Observers: Jean at al. (27 obs., 21 telescopes, Montreal, Canada, 3-6" refractors, reflectors) "A black, rectangular-shaped cloud vis. in M.Tranquill, moving W-E (IAU ?) & dissipated nr. term., surrounded by viol. colour. Bright yellow flash at 00:45, (obs. in response to request to obs. impact of Surveyor V at 0046) NASA catalog weight=3. NASA catalog ID #1043. ALPO/BAA weight=2.
On 1988 Jul 21 at UT 01:00? an Unknown observer (name and geographical position not given in the cameron catalog) detected a darkening on the floor of Proclus crater - this was also seen by other observers - some of whom were making observations independently. The Cameron 2006 catalog ID=330 and the weight=1.
Proclus NW ray 2003 Sep 03 UTC 02:46-03:07 Observed by Haas (Las Cruces, NM, USA) "The curious reddish edge to the conspicuous bright ray running N2 from Proclus is seen again (x321, x366 (S=1-3, T=3.5- 2.5). It lies on the SW side of the ray, with no corresponding blue border on its NE edge. The effect persists as the Moon drifts across the whole eyepiece field. However at 03:46 (x202) the coloured edge is not recognized now, but perhaps only because of worse conditions (S=3, T=2) 12.5" Newtonian reflector used." The ALPO/BAA weight=3.
On 2010 Apr 20 some time between UT 22:00 and 23:00 I. Bryukhanov (Minsk, Zeiss Refractor at the Minsk planetarium) observed an orange-brown tint a little to the west of Zollner and Kant craters. Apparently images were obtained. ALPO/BAA weight=1.
On 1969 Jul 20 at UT09:30 Whelan (Wellington, New Zealand, 10" and 6" reflectors. Other observers involved were: Mackrell (New Zealand, 6" reflector) and Spellman (4" reflector) observed Maskelyne crater undergoing a whitish glowing brightening. Shadowy filling of whole crater. Apollo 11 watch. The Cameron 1978 catalog ID=1179 and the weight=3. The ALPO/BAA weight=2.

Hue seen thruout obs. (true ground color? or seeing ? or true LTP?) thin clouds. (Apollo 10 watch)". NASA catalog weight=3 average. NASA catalog ID #1141.
On 1970 Apr 13 at UT09:00-09:03 Whelan (Walters, New Zealand, using a 10" reflector) observed Menelaus to have a deep red cloud that seemed to surge upward from outside the southern edge of the crater wall and disperse around the outside edge, spreading out on reaching Mare Serentiatis. All clear again though by 09:03UT, (Apollo 13 watch). Drawing supplied. Cameron 978 catalog ID=1246 and weight=3. ALPO/BAA weight=3.
Alphonsus 1960 Jan 06 UT 18:00 Observed by Warner and Hole (London, England, 18" refractor and 24" reflector, Moon blink used) "Red spot. Hole saw this on several other occasions(indep. confirm)." NASA catalog weight=5 (very good). NASA catalog ID 727.
Jansen 1966 Aug 24 UT 04:15-04:25 Observed by deBerard (Flossmoor, IL, USA, 6" reflector, x360, S=V, moonblink used) "Bright green glow -- using red & blue filters & green polariz. filter." NASA catalog weight= 3 (average). NASA catalog ID #965.
On 1988 Jul 22 at UT 02:15-04:00 P.W. Foley (Kent, UK, 11" reflector) made a sketch of a dark area of the (East) floor of Proclus that revealed a large anomalous dark region - there should be no shade here when the sun is at an altitude of above 50 deg!. BAA lunar section archives reveal similar dark shadings - however on this night it was a different shaped dark area. The appearance was confirmed by several observers. Foley reported that the region affected stretched from Proclus to Theophilus. The TLP was seen in the USA too by D, Darling as early as 01:31UT and by others on his TLP network - brightness measurements of the "c.p." were 3.5 and the remainder of the floor was 5.5. However the observers did not all agree on the same position for this dark area. The Cameron 2006 catalog ID= 331 and the weight=2. The ALPO/BAA weight=2.
On 1941 Jan 06 at UT04:00 Barcroft (Madera, CA, USA, 6" reflector) saw an anomalous shadow in Arzachel crater. Cameron 1978 catalog ID=482 and weight=3. ALPO/BAA weight=3.
Flash seen in Ptolemaeus (A?) - possibly a meteor. Cameron 1978 catalog weight=1. Cameron 1978 catalog ID=863.
Herschel 2005 Aug 13 UT 00:07-00:29 Observed by Daniel del Valle Hernandez (Aguadilla, PR, 8"SCT, x225, S=7, T=4) "Interesting configuration of shadows with umbra and penumbra. Effect seemed to reduce over time." An ALPO report. The ALPO/BAA report=2.
2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw Mons Pico to be incredibly bright. Adee reported naked eye visibility, though this does not show up in later CCD images. Jarwaski saw another nearby Mt very bright as well. This has been assigned an ALPO/BAA weight of 1, though I suspect it is just normal for Pico to get quite bright at sunrise.
Patches of brightness seen in the area between craters Aratus and Joy. Seemed to the observer to be perhaps slightly brighter than one would expect - the observer thought that their observation only barely constitured a TLP but decided to send the report in anyway. This has been assigned an ALPO/BAA weight of 1.
On 1983 Sep 15 at UT 05:20-05:24 Louderback (South Bend, WA, USA, 8" reflector and 3" refractor, seeing poor) found that the west wall of Eimmart was unusually bright (8.3) and apparently it was almost as bright as the "WEBS(of Aris?) at its brightest". The crater was apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID= 228 and the weight=3. The ALPO/BAA weight=2.
Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson, Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw something in Proclus, alerted Jamieson who saw nothing unusual at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw Proc. fluctuate. Red & blue filters showed some reduction in brightness. E. edge showed darkening, but not as dark as in shadows. 10 min later, returned to normal. (Sparks confirmed Dean)." NASA catalog weight=5. NASA catalog ID #1267. ALPO/BAA weight=3.
1970 Jul 11 UT 20:35-20:45 During a TLP alert for Proclus, Jamieson saw nothing unusual, but found instead that Secchi was quite bright. NASA catalog weight=5 (very good). NASA catalog ID #1267. ALPO/BAA weight=1.
Alphonsus 1958 Dec 19 UT 20:00? Observed by Wilkins (Kent, UK) described in the NASA catalog as: "Reddish patch on central peak" 15" reflector used. NASA catalog weight=4. NASA catalof TLP ID No. 711. ALPO/BAA weight=3.
On 1989 Jun 12 at UT 21:18-22:25 G. North (Herstmonceaux, UK, Coude, seeing=V) noted at 21:18UT that Torricelli B was "barely visible"- possibly this was seeing related. M. Cook (Frimley, UK, 8" reflector, seeing=IV) found Toricelli B to be ëxtremely dull - impossible to judge shadows on floor in contrast to Cens." Holmes (Rockdale, England, UK, 8" reflector, seeing=II-III) at UT21:30 also found Toricelli B difficult to find at magnifications less than 200x. Cameron comments that "Dulling is common on it at high Sun but illumination doesn't seem to be the cause or related". The Cameron 2006 catalog ID=365 and weight=5. The ALPO/BAA weight=2.
Eratosthenes 1954 May 11 UTC 20:00 Observer: Catermole (UK, 3" refractor) "Central peak invis. tho surroundings were sharp". NASA catalog ID #563, NASA weight=4 (high). ALPO/BAA weight=2.

Entire inside of crater seemed filled with haze or smoke. Shad. of E.wall was black & sharp. CP & floor seen thru haze. No other craters showed this appear. (date&time rep't=Sep3, 1830L.T)." N.B. Sun above the horizon at 02:30 - sun sets at Lick at 02:37! NASA catalog weight=4 (good). NASA catalog ID #264. ALPO/BAA weight=3.
On 1988 Jul 23 at UT03:07 D. Darling (Sun Praire, WI, USA, 12" reflector, x150, seeing = 6/10) discovered that the dark area on the floor of Proclus, seen earlier by UK observers was still present, but less so (?) and the shape changed. When viewed through a green filter it was less distinct. "Change with two other filters. Polarizer gave a circular shape with a knot on SE side & W58 in White." The measured brightness of Proclus was 9 on three sides and 8.5 on its west rim. The floor was 5.5, but the dark spot was 4. Alphonsus, Bullialdus, Copernicus, Eratosthenes, Plato and Ptolemeaus were all normal. The Cameron 2006 catalog ID=332 and the weight=1. The ALPO/BAA weight=1.
Tycho observed by G. North (UK) seen to have greyness inside parts of its shadow. Confirmed by J.D. and M.C. Cook Possibly light scattered of illuminated wall into shadow or highland starting to break through the shadow. ALPO/BAA weight=2.

" - indeed Haas in Stolling Astronomer 2002 Vol 45, p29 states that Cragg was amazed to see Plato's floor with absolutely nothing on it! He was able to draw details elsewhere in other features. NASA catalog weight=5. NASA TLP ID No. #551. ALPO/BAA weight=2.
Morales of France?, observed "an illumination" in Kepler on 1884 Feb 05 at UT20:00?. The Cameron 1978 catalog ID is 241 and the weight=1. The ALPO/BAA weight=1.
On 1972 Apr 22 at UT 17:30-18:15 Iwanoff (60mm refractor, 1000mm focal length,transparency 3 out of 5 and seeing 3 out of 5, located at 53deg 5' N and 8deg 45'E) At Censorinus a diffuse bright area, greater than the crater itself, yellow to white in colour. Published in Hilbrecht and Kuveler, Moon and Planets, 30 (1984) p53-61. ALPO/BAA weight=1.
On 1974 Mar 02 at UT 23:00 Fitton (Lancashire, UK, 8.5" reflector, x200, seeing = excellent and transparency = excellent) observed "A fine deep red line seen at 1st contact with B-ring of Saturn. Nothing unusual at A-ring contact. Persisted during occult. of B-ring. It divided into 2 components & space between B-ring & globe cutting ring into 2 disjointed ends persisted till dark limb passed onto globe of Saturn, then a short red line corresponding exactly to chord of planet disk defined by lunar limb. It increased in length as occult. progressed. It suddenly vanished after 3/4 of globe had been occulted. No afterglow at spot on limb, no irreg. at limb could be seen. Obs. eliminates Saturn, telescope, & atmosp. as possible cause. Suggests refraction from tenuous atm. of destructive interference of reflected light from very small angle at limb, or diffraction of Saturn light grazing limb". The Cameron 1978 catalog ID=1389 and weight=1. The ALPO/BAA weight=1.
Linne 1867 Jan 14 UT 20:00 Observed by Knott (England?) "White covering had seemingly disappeared, was a dark spot. Definition (seeing?) was poor." NASA catalog weight=1 very low. NASA catalog ID #148.
Shadow of central peak barely distinguishable. Residual wall shadow normal black. Landslip very conspicuous, 10 deg bright. Cameron 1978 catalog TLP ID=1040 and weight=4. Cameron 2006 Catalog Extension ID=12 and weight=4. ALPO/BAA weight=2.
On 1974 Mar 3 at UT 19:06-20:20 J-H Robinson (Teighmouth, Devon, UK, 10" refractor, x200, seeing=poor) got a Moon Blink reaction on the South east wall of Plato, adjacent to the rim shadow and alerted the BAA TLP network. Ford reported a negtive result at 19:35UT, although Robinson was still getting a blink reaction at 19:40UT, albeit fainter, red at times. Findlay at 19:43-19:52 and 20:00-20:05 saw nothing unusual. Robinson at 19:56UT no longer saw a blink, but it returned at 20:05UT. Light in bothred and blue filters. Not steady, but coming and going and gone at 20:09UT. Moore at 19:59-21:00, kennedy at 20:12-20:30, Taylor at 20:48-21:03 and Fitton at 20:05UT all got negative results. The latter time coincides with Robinson's second blink reaction.

On 1988 Jul 24 D. Darling (Sun Praire, WI, USA, 12" reflector, x150, S=7/10, T=3) observed the following in Proclus: "At 0213 the previously observed gray area was 1/3 of July 22 and V shaped and fanned out across the floor. Could see hint of knot seen before. Craters named in 7/23/88 (#319) were all normal this time too". Is it possible that this report refers to the crater "Gray" rather than "Proclus" as the column field suggests in the Cameron catalog? The Cameron 1978 catalog ID=333 and weight=5. The ALPO/BAA catalog weight=2.
On 1981 Sep 08 at UT 21:28-21:34 P. Madej (Huddersfield, UK, seeing III-IV and trasnaparency good) observed a light orange transparent cloud extending from the north east inner corner across over the floor of Plato. Camero comments that this report was confirmed by 3 othr observers. The shape of this clud varied. The Cameron 2006 catalog ID= 153 and weight=4. The ALPO/BAA weight=3.

On 1975Mar22 at UT 21:17-21:23 Findlay and Ford (Mills Observatory, Dundee, UK, 25cm refractor, Wratten 25 and 44a filters used) A white spot was observed on the rim of Bulialdus that was perhaps slightly brighter in red than in white light. The observers however decided that they did not regard this as a TLP. This is a BAA Lunar Section Observation. ALPO/BAA weight=1.
Gassendi 1979 Dec 29 UTC 20:09-22:04 - Observer: Cook (Frimley, Surrey, UK) "Colour seen - almost certainly spurious colour and not a TLP". ALPO/BAA weight=1.

On 1963 Nov 28 at UT 05:00-06:00 Greenacre, Barr, Hall and Dungan (Flagstaff, AZ, USA, 24" refractor) observed a deep violet area form on the western exterior of Aristarchus, and a less deep violet area form to the eastern edge of Aristarchus. As these were becoming stronger, a blue-like haze formed on the sunlit floor of Aristarchus, that obscured underlying detail. The ALPO/BAA weight=2.
Alphonsus 1966 Aug 28 UTC 06:00-08:00 Observers from Astronet (Tucson, AZ, USA). NASA catalog states: "Brightenings in 2 dark patches & near fainter (40%) dark patch (40% of way from the c.p. to W. wall). 21" x200 reflector used. NASA catalog weight=2 (poor). NASA catalog TLP ID No. 969.
Herodotus 2002 Sep 18 UT 22:00 Observed by Raffaello Lena (GLR, Italy). Event described was of two pseudo-peak/hill-like features, one on the southern floor of the crater, and another just slightly to the NW of the centre. on the southern floor of the crater. Lena suspects a combination of seeing effects and albedo markings on the floor. However this effect of two spots on the floor has not been repeated again.For further information, theory, and a sketch please see Fig 5 in this web link: http://utenti.lycos.it/gibbidomine/analisi123.htm ALPO/BAA weight=2.

Alphonsus (black spot, upland #1) 1965 Oct 08 UT 05:48-08:23 Observed by McCord (Mt Wilson, CA, USA, 60" reflector + spectrograph) "Line depth ratios a/b(H?), c/d (K?) were significantly low for upland #1 & abnormally high for Alphonsus black spot, but not as pronounced as the other area was high compared with 23 other areas" NASA catalog weight=5 (very good). NASA catalog ID #899.
Schickard 1944 Aug 31 UTC 21:00? Observed by Wilkins (Kent, England) described in the NASA catalog as: "Saw a mist in it which was gone next nite. interor was dotted with white spots, contrasting sharply with dark areas. All very clear on Aug 15 at sunset". 8.5" reflector. NASA catalog weight=4 {high). NASA catalog TLP ID No. #492. ALPO/BAA weight=3.
Plato 1976 Jan 14 UT 20:50 Observed by J.H-Robinson (Teignmouth, UK, 26cm Newtonian, Wratten 25 and 44a filters, x200, seeing fair to poor). The Plato floor patches were clearer in red than in blue light. ALPO/BAA weight=1.
On 2010 Apr 27 at UT 00:10-00:30 and 01:45-02:00 P. Grego (St Dennis, UK, 20 and 30cm reflectors) noticed a craterlet just to the east of Briggs and an E-W trending lineament or wrinkle ridge that did not show on NASA LAC charts. Further checks did not reveal it on Lunar Orbiter mosaics, but the craterlets (and not the E-W trending ridge) were visible in LROC topography data. The ridge is possibly a very low relief feature that shows only under very shallow illumination conditions. The ALPO/BAA weight=1 until we get confirmation at repeat illumination.
Aristarchus 1967 Sep 17 UTC 02:05-02:21 Observers: Delano (Fall River, MA, USA) and Corralitos Observatory (Organ Pass, NM, USA).

The NASA catalog states the following: "A rimtop cratelet on SW rim appeared almost as bright as c.p. thru a Wratten 25 filter (red) but no brighter than a lower central wall & rim thru a Wratten 48 (blue) filter. Inner W. slope of craterlet displayed a bright red color which became less & less noticeable until 0212h It was no longer brighter than other parts. At 0217 it flared again brighter red for 1m. (indep. confirm. of Seeliger for activity in Aris. ?) Corralitos MB did not confirm. NASA catalog weight=4. NASA catalog TLP ID No. #1045. ALPO/BAA weight=2.

On 1983 Sep 20 at UT 05:08-06:13 Louderback (South Bend, WA, USA, 3" refractor, x150, seeing poor and chromatic aberation on the limb) detected "purple"in the vicinity of Aristarchus crater and this was stongest on the north and north west external rims, however there was no "violet glare"from inside the crater. However the region of the central peak was very bright - though he could not detect the central peak. The brightness of the TLP was 4.5 and it should normally be 3 (nimbus area). Near the "big plain"it was 7. The chromatic aberation seen on the crater. There was also violet on the northen wall of Herodotus crater and the Cobra Head. Ït appeared dark blue in the blue filter", the surrounds remained gray". Apparently on the 26th the"ring was still dark with faint violet - nearly normal". Cameron comments that the TLP was due to spurious colour. The Cameron 2006 catalog ID= 229 and the weight=3. The ALPO/BAA weight=2.
On 1975 Mar 25 at UT19:59-20:02 P.W. Foley (Wilmington, Dartford, Kent, UK, 30cm Newtownian) observed blueness along the inner southern wall of Plato. This is a BAA report. The ALPO/BAA weight=1.

On 1983 Oct 19 at UT 21:09-23:40 G. North (Bexhill on Sea, UK, seeing III) found Aristarchus crater to be slightly blue in colour, and very bright, despite the fact that no colour was seen elsewhere on the Moon. At 22:08UT Foley (Kent, UK, 12"reflector, seeing II) obtained an extremely high CED brightness measurement and also picked up a "blue- violet" cast, especially inside the west rim, furthermore he saw noe detail in it. The Cameron 2006 catalog ID=230 and the weight=5. The ALPO/BAA weight=3.

The ALPOS/BAA weight=2.
Aristarchus 1963 Oct 30 UTC 22:00? Scarfe (Cambridge, UK) observed a 30% enhancement at 540nm in the spectra of Aristarchus. The Cameron 1978 catalog ID No. is 778 and weight is 5. The ALPO/BAA weight=1 because Oct 30 is not mentioned in Cameron's refernce.
In 1963 Oct 30 UT 22:00? Scarfe (Cambridge, UK) observed a 30% enhancement at 540nm in the spectra of Copernicus. The Cameron 1978 catalog ID No. is 778 and weight is 5. The ALPO/BAA weight=1 because Oct 30 is not mentioned in the ref that Cameron give's to Scarfe's paper.

Herodotus 1968 Aug 09 UTC 02:05-03:45 Observed by Lowe (Springfield, VA, USA) described in the NASA catalog as: "With naked eye saw a bright spot in NW part of Moon; tho't it was Aristarchus, but 7x binoculars showed it to be Herod. which was brighter than Aris! still apparent at 0245h, but was normal at 0345h. (at FM, must have been an extraordinary event)". Naked eye and 7x binoculars used. The NASA catalog assigns this a high weight of 4. The NASA catalog TLP ID No. is #1087. Reference for observation is personal communication from the observer to Winified Sawtell Cameron. ALPO/BAA weight=3.
1974 Mar 08 UT 22:55 R. Livesey (Scotland, UK) noted that this crater was reddish, but suspected that it was an optical effect? ALPO/BAA weight=1.
On 1975 Mar 27 at UT22:30-01:45 P.W. Foley (Wilmington, Dartford, Kent, UK, 30cm Newtownian) observed blueness along the inner southern wall of Plato, though the centre of the activity was offset on one side. This is a BAA report. The ALPO/BAA weight=1.

The Moon, Longmans, Green and Co., London, 1876; Astron. Reg. 17, 204, 1877?
Plato 1944 Sep 03 UTC 03:40 - A.W. Mount (Fort Worth, TX, USA, Conditions good, seeing 6/10) saw a small white bright point of light appear suddenly close to the W. wall of Plato glowed briefly as by far the most conspicuous object in the lunar field of view and vanished quickly after approximately 2 sec. It was star-like in appearance and was stationary on the Moon's surface - about magnitude 6? Angular diameter of the flash was <= 1". Observing conditions good enough to see the central craterlet in Plato. 20cm reflector used. Ref. DJALPO Vol 45, p28 Spring 2003.
On 1963 Nov 01/12 at UT 22:30-03:00 P. Moore (UK, 12" reflector) observed something unusual in Aristarchus/Copernicus/Kepler - the Cameron catalog is not very clear which. The Cameron 1978 catalog ID=779 and weight=5. ALPO/BAA weight=1.

According to the Cameron catalog, Moore(12" reflector, UK) noted something unsual between 22:30 and 03:00 but this might apply to Kepler, Coperncius, and/or Aristarchus and that was seen 23:30-03:00? - the catalog is not very clear. The Cameron 1978 catalog ID=779 and weight=5. The ALPO/BAA weight=4.
Aristarchus 1939 Dec 27 UT 08:00? Observed by Barcroft (Madera, CA, USA, 6" reflector) "Faint bluish mist on inner W. wall (according to Firsoff it was right after SR, but this can't be as age=16d & SR comes at 11d)" NASA catalog weight=3 (average). NASA catalog ID #464.
In 1962 Sep 16 at UT08:05 Wildey, Pohn (Mt Wilson, CA, USA, 60" reflector) Taruntius faded from Vmag-3.21 to 4.04, a 0.82 difference in magnitude in 2.5 hours - a photometric measurement. The average magnitude for this age is 4.03, so therefore the crater had brightened by two times above normal. The Cameron 1978 catalogID=769 and the weight=5. The ALPO/BAA weight=3.
Mare Crisium 1965 Oct 11 UTC 10:10 Observed by McCord (Mt Wilson, CA, 100" reflector + spectrogram) "Line depth ratios a/b (H),, c/d (K) abnormally high compared with 23 other areas (including Aristarchus?)." NASA catalog weight=5 (very high). NASA catalog ID 902.

On 1989 Jun 20 UT 0628-06:58 R. Manske (Sun Praire, WI, USA, 1" refractor) discovered blue on the north west inner wall and red on the south east outer wall. At 05:39 he could see the blue but not the red. No colour was detected on Tycho, but he thought that he could detect a pinkish colouration over the whole Moon. The Cameron 2006 catalog ID= 367 and the weight=1. The ALPO/BAA weight=1.
Aristarchus 1983 Oct 22 UT 22:00 G.W. Amery, (Reading, UK, Seeing III-IV) found Aristrachus so bright that the CED was unable to give a reading. The crater's interior was also diffuse in appearance. The Cameron 2008 catalog ID=232 and weight=4. The ALPO/BAA weight=3.
Aristarchus 1969 May 03 UTC 07:00? Observed by Smith, Gallivan (Corralitos Observatory, Organ Pass, NM, 24" reflector, photos) "Bluing around crater. Visible on monitor, but immeasurable in photos" NASA catalog weight=5. NASA catalog ID #1125
On 1898 Apr 07 at UT 22:30 Pickering (Cambridge, Mass, USA, 15" refractor?) observed in Schroter's valley and it's vicinity "Variations in vapor col. Lge. gap in main column near edge of C. Gap not previously seen, but fine lines crossing it had. E is still most conspic. (time est. fr. col. given)". The Cameron 1978 catalog ID=298 and weight=3. The ALPO/BAA weight=2.
On 1980 Sep 25 atUT 20:20-22:14 P. Moore (Selsey, UK, 15"? reflector, seeing=III) found that Mons Pico was bright and had a reddish glow to its south west. The Cameron 2006 catalog ID=111 and weight=0. The ALPO/BAA weight=1.
On 1980 Sep 25 at UT20:20-22:14 P. Moore (Selsey, UK) noticed that the central craterlet was more visible in red than in blue. There was also a streak on the floor that was "shifted to S & W." The floor was dark and Mons Pico was bright. Peters found Plato's floor (and central craterlet) to be dark, and darker in blue than in red, however he was suffereing from spurious colour at his observing site. Cameron 2006 catalog ID=111 and weight=0. ALPO/BAA weight=1.
On 1980 Sep 25 at UT 20:20-22:14 Peters (Kent,UK, x240 and x120, seeing=III) observed Proclus to have an orange tint, however there was a lot of spurious colour in the area. The Cameron 1978 catalog ID=111 and weight=0. The ALPO/BAA weight=1.
2004 Aug 31 UT 22:30-22:35 C. Brook (Plymouth, UK) looked at Gassendi and noted a slight chestnut brown colouration in the dark area on the crater floor to the north of the central mountain leading to Gassendi A. It lasted for about two minutes during 22-30 hrs UT to about 22-35 hrs UT (observer unable be more precise). Used 60mm OG x120. Seeing quite steady trans good. Checked Gassendi again at 23hrs UT to 23-05. No sign of colour. Also area mentioned earlier seemed lighter now. No colour on Aristarchus. Plato floor dark -no sign of craterlets. Seeing good with just slight tremor. Trans good 60mm OG x120 used. The ALPO/BAA weight=2.
East of Picard (56E, 15N) 1877 May 29 UT 00:30 Observed by an unknown observer (in England?) "Bright spot. (nr. sunset, should normally be faint? as in Kuiper atlas where it is invisible.)" NASA catalog weight= 3. NASA catalog ID #191.
Plato 1965 Sep 12 UT 05:00 Observed by McCord (Mt Wilson Observatort, CA, USA, 60" reflector+spectrometer) "line depth ratios in spectra a/b (H), c/d (K) were abnormally high compared with 23 other areas, but not quite as pronounced as other areas on other dates." NASA catalog weight=5 (very high). NASA catalog ID 895. ALPO/BAA weight=5.
In 1950 Jul 02 UT07:22 Bartlett (Baltimore, MD, USA, 3.5" reflector) saw no dark bands on the inside of Aristarchus, despite detail being seen elsewhere. He would normally have expected to have seen bands at this colongitude, based upon past observations. The ALPO/BAA weight=2.
Aristarchus 1964 Oct 23 UTC 02:35-02:45 Observed by Bartlett (Baltimore, MD, USA, 3" refractor, 133 & 200x, S=3-5, T=4) "South floor region granulated, 6 deg bright with very faint trace of pale yellow color; rest of crater 8 deg bright." NASA catalog weight=4 (good), NASA catalog ID #859.
Aristarchus 1983 Oct 23 UT 19:00-01:30 Observer: Foley (Kent, UK, 12" reflector, seeing=II) noiced at 19:00UT an extended bright spot on E wall and extending beyond. This was brighter than other areas of the crater. There was also occasional star-like glistening. Foley comments that the inside of Aristarchus was slightly obscured. The TLP started fading from UT20:30 and finished by 01:30UT. six out of nine independent observers confirmed the effects seen. In total 14 observers observed, 9 reported back and 6 found abnormalities in Aristarcus though all encountered variable seeing conditions - some had spurious colour. Cameron comments that this was one of the best recorded/confirmed TLP events. All CED brightness measurements obtained were very high. Moore, Nicolson and Clarke (5" refractor and 15" reflector, 230-350xseeing III) found the crater to be very bright at 19:11UT through a 5" refractor and there was a blob on the east rim (Bartlet's EWBS?) at 19:14UT. Nicolson also saw a very bright star-like area on the eastern wall but this was not defined as it usually is. The crater was also very bright at 22:43UT using the 15" reflector available to these observers. At 01:07UT they used a Moon blink and discovered that the bright region was bright in blue light and less bright in red - although this was not a detactable blink when switching rapidly between filters. They found that the crater had returned to normal by 01:15UT. M.C. Cook (Frimley, UK, seeing III-IV) observed a large diffuse spot on the east of the crater that was brighter in blue than in red light and the CED device gave a high reading. J.D. Cook (Frimley, UK, seeing III-IV) made a skecth that showed the bright spot extended on the east wall - again the CED reading was high and a lot of detail was visible on the floor. A.C. Cook (Frimley, UK, seeing III-IV) also noted remarkable detail and the bright (as confirmed by CED) blob on the eastern rim. G. North (Sussex, UK, seeing III-II) also confirmed the bright blob on the eastern wall. Wooller found the north west wall was a dirty yellow colour - though no colour was seen elsewhere in or outside the crater. Mosely found the crater to be bright and his sketch revealed the extension of the bright blob on the eastern rim and again a great deal of interior detail. Amery (Reading, UK, seeing III) found Aristarchus to be "a brilliant splash against dulled background in violet filter, especially polarizing filter. CED + polarizer readings high, but not as high as previous night". Mobberley (Suffolk, UK, seeing III-IV) remarked that "spurious colour a total mess around Aristarchus & nothing abnormal seen". A photograph was taken at 20:50UT reveals the bright blob and entire detail. Peters (Kent, UK, seeingIII-II) observed Aristarchus with a UV screen from 20:15-21:23UT and comented that althogh being very bright, there was no variation between white and UV. It was checked with a Moon Blink device and the radial bands were clearly seen in white light, < in blue. The Cameron 2008 catalog ID=233 and the weight=5. The ALPO/BAA weight=4.
On 2002 Sep 23 at UT22:45-23:56 C. Brook (Plymouth, UK) noticed that the bands inside Aristarchus varied (UT22:45-22:56) in definition whilst the rim of Herodotus and the rays of Kepler and Copernicus remained sharp. These bouts of variation were 1-2min in duration. At 23:56UT when he checked again the periodic blurrings of the bands were still present. The observer suspected atmospheric effects. M.Cook (Frimley, UK) observed 22:00-22:30 and could see only 2 bands on the west wall - but this may have been because of poor transparancy. The ALPO/BAA weight=1.
In 1962 Sep 16 at UT08:05 Spirad (Victoria, B.C., Canada, 48" reflector) obtained a spectrum with a UV emission, in H & K lines compared to Jupiter and Mars. II-AO plates, 6A/mm dispersion. Fraunhofer lines much shallower than planetary ones. (whole Moon). The Cameron 1978 catalog ID=770 and weight=5. The ALPO/BAA weight=4.
On 2013 Dec 19 N. Longshaw (Oldham, UK, Seeing III, TAK FS 78 APO Refracror) observed a diffuse area east of the central peak of Geminus, to be sepia/brownish tint. The ALPO/BAA weight=3.
On 1989 Jun 21 at UT07:03-07:27, R. Manske (Sun Praire, WI, USA, 1 "refractor) found the colours pink and blue on Aristarchus, like the previous day, however this time there was also an orange tinge on the "back"" (North?) rim of Sinus Iridum and the same too on mare Crisium, all the way past Plato, in the direction of Cassini. This colour was not seen at higher magnifications. The Cameron 2006 catalog ID=368 and the weight=0. The ALPO/BAA weight=1.
On 1989 Jun 21 at UT 07:03-07:27 R. Manske (Sun Praire, WI, USA, 1" refractor) saw orange on Cassini all the way past Mare Imbrium edge, Plato etc - maybe atm. At high power (8mm eyepiece) & no filter. Saw no hint of color (due to smearing at high power?)." The Cameron 2006 catalog ID=368 and the weight=0. The ALPO/BAA weight=1.
On 1989 Jun 21 at UT 07:03-07:27 R. Manske (Sun Praire, WI, USA, 1" refractor) saw orange on Mare Imbrium edge all the way past Plato upto Cassini - maybe atm.

Using a 15.2 cm refractor he conducted a Moon blink search with Wratten 25a and 38a blue filters. His report goes as follows: Moon Blink carried out. In Red 25 Proclus looked nearly the same as in white light. Through the Blue 38a filter, however, only the brilliant lit south east wall was clearly visible. The northeast wall was very dim with this filter. With no filters the NE and SE wall were brilliantly lit, the SE wall was almost as bright as Aristarchus. A thread like strip along the NW wall, possibly the rim of the crater, was also brilliantly illuminated. The interior of the crater was a featureless stygian black with the exception of a brilliant (intensity 9) thread of light that ran parallel to the illuminated east wall. Whether this was an L.T.P. or an optical effect of atmospheric turbulence is unknown, did not see anything similar elsewhere along the terminator though" ALPO/BAA weight=3.

On 1989 Apr 26 at UT 10:22-10:44 D. Darling (Sun Praire, WI, USA, 3" refractor, x36-x140) found that the eastern half of Plato crater was dark - and he checked this using several eyepieces. moderate magnification resolved the dark region into bands, but too high a magnification (x140) made the bands dissappear. The Cameron 2006 catalog ID=362 and the weight=0. The ALPO/BAA weight=1.

Tycho 1983Aug30 UT 00:15-00:18 R. Moseley (Coventry, UK, 6" f/10 reflector, x60, transparency very good, seeing III, improving with altitude) attention initially caught by the impression of a rosy colouration along the NW crest and outer wall. For perhaps 2-3 min this persisted - before fading entirely. The observer felt that the cause may have been psysiological - or short-lived spurious colour. However interestingly nearby craters did not show the effect. A sketch was made over a longer time span 00:15-00:40UT. ALPO/BAA weight=1.
On 1982 Aug 11 at UT03:30-04:15 Mobberley (Suffolk, UK) obtained a photograph and made a sketch that revealed a needle-like shadow from the west wall to near by the central craterlet - the latter was quite clearly visible.

There was one on the north and the other two in the south west to south. They lasted approximately 30 minutes and then promptly vanished. Cameron says that it cannot be this date because the Moon was not visible at 17:00UT Suggests 05:00-05:30UT? The Cameron 2006 catalog ID ID=189 and weight=3. The ALPO/BAA weight=2.
On 1978 Jan 06 at UT 01:00 Anorati (Firenze, Italy) observed inside a "good sized crater?" an orange light that became bright green. The efect did not recur over the many hours of observing.

On 1969 Jul 20 at 22:50-23:15UT Jean Nicolini (Sao Paulo, Brazil, 12" reflector x430, S=II.5-III.5) saw a weak reddish area on the north west(east?) wall of Eudoxus crater. An English Moon Blink device showed it dark in blue and opaque in red. Reddening remained unchanged while comparing it to adjacent region and Aristotles. Colour index was toward dirty orange. Colour most apparent in the good moments of seeing and disappeared in the poorer moments of seeing, Cameron says that this is opposite to what was expected if the effect was atmospheric in origin and no colour was seen in Aristotles.
