Cook (Frimley, UK, 3.3" Questar telescope, x80-x130, atmosphere hazey - poor transparency) noticed that the east side rims were slightly fuzzy and suspects that this might have been due to the illumination angle. A.C. Cook (Frimley, UK) obtained some CCD images that revealed that the effect was to some extent still there one hour later. The Cameron 2006 catalog ID=461 and the weight=5. The ALPO/BAA weight=2.
On 1931 Mar 27 R.Barker (observing from Cheshunt, UK, 12.5" reflector) found that the central mountain in the brilliant ray crater Tycho was a curious shade of grey. This was despite the interior of Tycho being fully in shadow. Cameron 1978 catalog ID=400 and weight=3. ALPO/BAA weight=3.

On 1982 Jun 30 at UT 02:05-02:15 Marco Petek (Porto Alegre, Brazil) found that the region between Eratosthenes and Bode (7W, 13N) looked like it had a darkening (cloud?) that had even darker points inside. The Cameron 2006 catalog ID=172 and weight=3. The ALPO/BAA weight=2.
Tycho 2003 May 10 UTC 03:15 Observer Robert Spellman (Los Angeles, USA) - "CCD video of spur-like features coming off N & S edges of central peak - spurs pointed eastwards". It is now thought that this effect is almost certainly seeing flare as it is visible on other features in the image, although to a much lesser extent. The ALPO/BAA weight=1.
Proclus 1972 Jul 19 UT 21:24-21:30 observed by S.Westmoorland (Cropwell-Bishop, UK, 15cm reflector, x48 & x96, image dull but steady) observed a brilliant spot in the NE (IAU?) wall which lasted for about 90 seconds. After fading it was replaced by pulsations for a further 2 minutes. Clouds prevented further observations. ALPO/BAA weight=1.

Peirce A 1927 Dec 03 UT 22:00 Observed by Wilkins (England, 15" reflector) "Invisible (date in MBM) is wrong, would be only 6h before NM. Sunrise on crater is at 3d & ? h. No interposition of dates works e.g. 13th or 1926 or Dec 26 1923. Only Dec 3 1927 is feasible as it would be just after 1st Q. & more similar to the May obs.)" NASA catalog weight=4? NASA catalog ID #396. ALPO/BAA weight=2.
On 1968 Oct 01 at UT 21:00? Bartlett (Baltimore, MD, USA) and Beck (Ohio, USA, x437) observed lack of detail on the floor of Plato, however the wall of the crater was easily resolved. Cameron says that this was an independent confirmation. The Cameron 1978 catalog ID=1092 and weight=5. The ALPO/BAA weight=3.
W. of Mare Humorum (50W, 25S) UTC 00:00? Observed by Mac Farline (England?) "Bright Point" NASA catalog weight=2 (low). NASA catalog ID 719.

On 1980 Aug 21 at UT20:00 J.H. Robinson (Teighmouth, Devon, UK) detected colour, using a Moon Blink device, and "mistiness" on the southern floor of Tycho crater. The seeing was poor! Cameron 2006 catalog ID=104 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=1.
Deslandre - 1965 May 12 at UT 19:10 E. Penzel (Rodewisch, East Germany) was taking a sequence of images during the impact of the Soviet Lunik 5 (upper stage of the carier rocket?). He detected a tens of km scale elongated cloud after the impact over a duration of 9.5 minutes. This was near to Deslandre crater. However there are differences between the images elsewhere on the Moon, possibly due to different exposures or some other effects and it is not 100% sure that what he detected was impact debris/cloud?. The ALPO/BAA weight=1.
Plato 1873 Nov 01 UTC 20:00? Observed by Pratt (England?) "Unusual Appearance". NASA catalog weight=1 (very low). NASA catalog ID #182. ALPO/BAA weight=1.

On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in Gassendi - some obsevers detected colour, others did not. P. Moore did not notice anything unsual earlier at 18:50-19:00, though his seeing was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did however notice a small reddish spot to west of central ridge, but by 20:30UT the colour was less obvious, but the spot was back again at 20:45, but not easily seen at 21:00 and gone completely by 21:45UT. N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red patches on the floor between 20:54 and 21:31UT. A BAA Lunar Section report. ALPO/BAA weight=3.
Gassendi 1968 Oct 03/04 UT 19:30-19:50 & 00:20-01:40 Observed by Rawlings (Aylesbury, UK, 6" reflector low magnification) and by Moore (Selsey, Sussex, UK, 12.5" reflector, x360) "Slight blink (Eng.) arcuate in shape, N. of c.p. (Rawlings dubious). Moore, with blink device saw none at 0020-0140h. No LTP in Gass., Ptol. or Aris. 5th or 6th.". NASA catalog weight=1. NASA catalog ID #1093. ALPO/BAA weight=1.
On 1964 Jun 21 at UT 21:18 Lipskii and Pospergelis (Shternberg State Ast. Institute, AZI-2" reflector (Cass.) observed Aristarchus: "Polarization meas. with electron polarimeter. Plane of polariz. rotated 2deg fr. the adjacent areas. They interpret it as some scattering medium over the crater. (Source gave date as 6/31/64, misprint =21st?)". The Cameron 1978 catalog ID=820 and weight=5. The ALPO/BAA weight=4.
On 1980 Aug 22 at UT20:15-21:29 J-H Robinson () detected violet on the west wall of Aristarchus. Cameron 2006 catalog ID=105 and weight=5. ALPO/BAA weight=2.
On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK, 12" reflector, x200, seeing=II) noticed in the area south east of Manilius that it was brighter in red light than in blue light at 20:15UT whereas 1 minute later it was the same brightness in each filter. The effect reappeared at 20:21UT and was particularly strong at 20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was of high reflectivity in white light and was bright in red at 21:15UT, thougjh the south east area stopped giving a colour reaction at 21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT however at 23:55UT it was surrounded by a transient white ring that varied in visibility in an irregular way. Foley found Manilius B had a vivid blue interior and in blue light the ring was black. and not at all seen in red or white light. The CED brightness measurement varied from 1.9 to 2.4. All other regions observed were normal in brightness. Violet was seen on the west wall of Aristarchus though. M.Price (Camberley, UK) found a possible blink in Manilius B but was observing under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5. ALPO/BAA weight=4.
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.
On 2003 May 13 at UT06:40-07:26 W. Haas (Las Cruces, NM, USA, 12.5" reflector, x321 and x202, S=2, T=3.5) suspected (06:40-06:55UT) that he saw an oval bright feature (intensity 5.5) near the centre of the floor of Herodotus crater indenting into the shadow - however the seeing was none too good, so it is more of a suspicion than a definite sighting. At 07:14-07:26UT he re-examined the region (x202 and x321, S=1-2 and T= 3.5) and had better glimpses that conformed his initial suspicions of there being an oval indentation bright spot (now intensity 6) into the shadow in the centre of the floor. Of course Herodotus does not have a central peak! There was also a very bright spot on the NW> sunlit rim of Herodotus crater. The ALPO/BAA weight=2.
On 1825 Jan 01 UT17:00? an unknown Russian observer noticed a cloud in Mersenius.
Herodotus 1950 Mar 30 UT 19:00? Observed by Wilkins (Kent, UK, 15" reflector) "Transient c.p. (similar phen. to Bartlett's in later yrs.? see #532). NASA catalog weight=4 (good). NASA catalog ID #523. ALPO/BAA weight=3.
Herodotus 1956 Nov 15 UT 01:05-01:30 Observed by Bartlett (Baltimore, MD, USA, 3.5" reflector x100) "Pseudo c.p. clearly seen est. I=5.5, wratten filters showed it neutral to green, red, & yellow, but duller in blue. Floor est. 2deg, distinctly olive-green. Precise time at 0117 at col. 55.27deg" NASA catalog weight=4. NASA catalog ID #655. ALPO/BAA weight=3.
Herodotus 2022 Nov 06 UT 00:05-00:38 A. Anunziato (Parna, Argentina - 105mm Meade EX 105, x154). Glimpsed an elongated light patch on the floor, slightly east of the centre of the floor. Observer was a bit uncertain if this was a genuine observation, or a biased observation – based upon the written account in the repeat illumination predictions. Detailed sketch made. Anyway, seeing detail on the floor of Herodotus was at the limit of his telescope. We shall therefore assign an ALPO/BAA weight of 1.
Aristarchus area 1967 Apr 21 UT 19:00-21:20 Observed by Darnella (Copenhagen, Denmark, 3.5" refractor, S=1-2), Farrant (Cambridge, England, 8" reflector, x160), Corralitos Observatory (Organ Pass, NM, USA, 24" reflector with Moonblink) "On exterior wall of Aris., 3 pts. in Cobra Head & banks of valley were star-like & glowing; & Herod. were red. Farrant could not bring hill N. of Herod. into focus. He says color was deep red-orange & steady for 3 min. Started at 1915h (1916-1925h seeing was too bad) (indep. confirm.). Suspected next nite but bad seeing. Not confirmed by Corralitos MB." NASA catalog weight=5. NASA catalog ID #1030. ALPO/BAA weight=4.
On 1995 October 6 at UT 21:30 R. Lena (Rome, Italy - a UAI observer, 11.4cm reflector) saw 4 or 5 flashes from Herodotus crater. Light intensities (mag?) ranged from 9 to 8 and they were brighter through a red filter. There is no 2006 Cameron catalog entry for this observation - it has come from the UAI web site. The ALPO/BAA weight=3.
On 1995 Oct 06/07 at UT 22:45-00:00 P. Mirteto (a UAI observer, RI, Italy, 20cm reflector) observed some brightness changes in Herodotus. Please note that this description is a summary of the material on the UAI web site. The ALPO/BAA weight=2.
On 1995 Oct 06/07 at UT 23:05-00:00 P. Mirteto (a UAI observer, RI, Italy, 20cm reflector) observed some brightness changes in Prinz. Please note that this description is a summary of the material on the UAI web site. The ALPO/BAA weight=2.
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.
On 1988 Sep 23 at 19:40-19:55 & 20:36-20:41 G. North (760mm Coude Rrefractor, x250, Royal Grenwwich Observatory, Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55 image very unsteady. All seems normal in other crtaters with the exception of Arcimedes. Much of the rim seems indistinct apart from a 1/4 length of the west rim. Strongly suspected that this was due to a combination of seeing and illumination. UT 20:02-20:06 - checked the area with a lower magnification 10" Astrographic Refractor - the crater seems more normal, so suggesting that the theory was correct. 20:36-20:41 returned to the 30" reflector, and the crater appeared similar to the start of the session. This is almost certainly not a TLP, but it would be helpful to have some images or sketches to check this theory out. Weight=1.
On 1987 Mar 13 at UT02:00-03:00 De Groof (Belgium, 8" reflector x150, seeing=clear) noted that the north west part of Aristarchus had a blood red shimmering filling the whole crater. A video by Mobberley some 18 hours later, shows variation in Aristarchus. Cameron 2006 catalog ID= 301 and weight=5. ALPO/BAA weight=3.
Aristarchus, Herodotus 1963 Dec 28 UTC 15:55-16:26 Observered by Yamada et al, (Hiroshima, Japan, 10" reflector, x278) "Red area, spreading to Herod., a perculiar obscuring gray area on N. edge of glow.

On 1983 Dec 17 at UT 17:25-19:20 Moseley (Covington, England, UK, x120 and x240, seeing=III and spurious colour present) found that the inside of Aristarchus crater was dull and slightly blue. Suspected the colour to be spurious: at 19:20 at x240 the colour was pink but at x120 there was no colour. Cameron 2006 catalof ID=234 and weight=3. ALPO/BAA weight=2.
On 1960 Sep 04 at UT00:00? Miranova (Russia or Israel) observed a TLP at an unnamed lunar feature: "Spectral photom. of some lunar obj. in 4250, > 5000A bands. Spectral plates". Cameron suspects luminescence? The Cameron 1978 catalog ID=730 and weight=5. The ALPO/BAA weight=1.
Aristarchus 1975 May 23 P.W. Foley (Wilmington, UK, 12" reflector, x200, x360, x624, atmospheric clarity good, seeing III from 20:15-22:30, but the clouded out at 22:30, and from 23:15-01:15 seeing was IV-V with poor transparency) observed (22:20-20:45 UT) variation in the SE corner of the Aristarchus, namely the usual dark bands were alternating light to dark, not in keeping with otyher crater features. This effect was not linked to atmospheric turbulence. Also projected image of bands beyond the crater W. wall were repeatedly noted. The observer broke away from observing at 20:45UT to make a telephonealert call. At 20:55UT they noted that the area between Vallis Schroteri and Herodotus seemed very light/bright, also the E. exterior of the crater wall of Herodotus. From 21:01-21:11 A slight blueness was seen to extend from the NE corner of Aristarchus, along the exterior rim, acrossand beyond Herodotus to the SW. A tgorough search was made of many bright areas, both near the terminator and to the E., but no blueness could be detected elsewhere. A slight orange hue was noted along the E. limb of theMoon (Spurious colour). From 21:18;22:30 Aristarchus seemed normal again, and likewise the head of Vallis Schoteri too. The observer was clouded out from 22:30-23:15and from 23:15-01:30 the seeing was so appaling that no colour or projection of the bands could be seen. A Moon Blink was used during the session, but no colour was detected in this? Another observer, R.W. Rose (Devon, UK) observed 21:20-21:30 but had IV seeing, and saw nothing unusual, but commented that if TLP wactivity had been taking place, then they would probably not have seen it. The ALPO/BAA weight=1.

Moretus? 1871 Dec 25 UTC 22:00? Observed by Webb? (England?, 9" reflector?) "Internal twilight in crater #132- a large circular crater nr. S.pole (crater #132 on Goodacre's map is Plato. Webb's map?)" NASA catalog weight=3 (average). NASA catalog ID #173.
On 1977 Apr 02 at UT22:00-00:00 L. Fitton (Shaw, Lancashire, UK, 8.5" reflector, x200, Wratten 25 and 44A filters, seeing II-III, transparency, good) noticed in Aristarchus, blue to the north west (IAU?) internal wall, also blue observed in other small bright objects against dark backgrounds. Lunar rotational axis and optical normal related such that the normal runs NW-SE (IAU?) through these features. Observer deduced that the coliur was obviously spurious and no blink was seen in any feature. The blue disappeared as the lunar altitude increased and no blue seen by 00:00UT. This is a BAA lunar section observation. The ALPO/BAA weight=1.
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.

During an eclipse of the Moon the crater appeared normal until it emerged from the shadow. In the north east the dark floor was not its normal hue and two light areas appeared to join. The emerging patches became less and less bright, finally disappearing at 0345 UT when the crater returned to normal. Cameron 2006 catalog extension ID=10 and weight=2. ALPO/BAA weight=2.
1963Dec29/30 UT 22:00-03:00. Doherty (Small Thorne, UK) 8.5" reflector, x110, x200 & x274, S=8-8.5, T=8, Moon 57 deg in alt) and 3 others, using the same instrument, saw a bright purple- blue patch in Aristarchus. Other areas checked for colour and none sen elsewhere. Attempts were made to contact observers elsewhere but with no success. Sketch made and shows the patch covering the floor area of Aristarchus and extending out beyond the east rim. Patch was elliptical in shape and the semi-major diameter was approximately 2/3rds of the diameter of Aristarchus, or about 27 km. The event lasted 5 hours and gradually faded. NASA catalog weight=5 (very high quality)". ALPO/BAA weight=4.
