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.

On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9 refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP in Macrobius. His report is as follows: "Blinked Macrobius with Wratten Filters Blue 38A and Red 29. Macrobius became almost invisible through the Blue 38A and essentially the same as in white light through the Red 29. The interior of the crater was completely in shadow. The only part of the east wall that was visible was an apparent high point still in the sun and seen as a bright point of light. This faded into darkness before 13:56UT. No sign of any illumination of the east wall crater interior or the interior of the west wall was seen during the observation period. The outer west wall was a rough looking, complicated mix of deep shadow and illuminated sunlit terrain." The observer concluded that there was not a TLP - although he did get a filter reaction, this may have been due to the different densities of the filters? ALPO/BAA weight=2.

(albedos disagree at same phases, so are real anomalies). (normal here?)." NASA catalog weight=4 (high). NASA catalog ID #461.
Alphonsus 1966 Apr 20 UT 22:28 Observed by Smith (Nottingham, England, 10" reflector) Reddish patch possibly detected on SE flank of central peaks, but more dubious than that from 28th Apr. ALPO/BAA weight=1.
On 1987 Mar 09 at UT20:00 M. Mobberley (Sussex, UK) obtained some video of Mons Pico - apparently these show the mountain with a puzzling appearance (not sure whether it was the observer who claimed this or some one who analyzed the tape). The Cameron 2006 catalog ID=300 and the weight=5. ALPO/BAA=1.
Gassendi 1966 Apr 30 UT 21:30-23:28 Observed by Sartory, Ringsdore (England, 8.5" reflector, S=E), Moore, Moseley (Armagh, Northern Ireland, 10" refractor, S=VG), Coralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moon Blink) "English moon blink system detected red spots with vis. confirm. Ringsdore says no color but saw obscuration. (LRL 60-in photos showed nothing unusual by my casual inspection). Indep. confirm. (even E. wall was in dark). Corralitos did not confirm by MB." N.B. event had finished by the time Corralitos came on-line. NASA catalog weight=5. NASA catalog ID #931. ALPO/BAA weight=4.
Eratosthenes 1968 Nov 01 UT 01:50-02:06 Observed by Chilton (Hamilton, Canada, 12" reflector, 300x) "Red glow in the crater. Weak blink beyond ESE (IAU?) wall. Visually, area would not focus & gave impression of fog cascading down slope, but no motion was vis. (Moore has misprint in time in his cat. extension -- should be 0150-0206)." NASA catalog weight=3. NASA catalog ID 1106. ALPO/BAA weight=3.

On 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6" reflector) took some photos (albeit out of focus) that showed a bright spot on the west rim. Cameron comments that this spot was sharp compared to the rest of the photograph, so was probably a photographic artifact. The effect was not seen in the finder scope. The Cameron 2006 catalog ID=103 and weight=2. The ALPO/BAA weight=1.
Aristarchus 1966 May 01 UT 21:55-22:45 Observed by Paterson, Brown, Sartory, Ringsdore (England, 12" reflector x252 for the former and 8.5"? reflector for the latter) "Eng. moon blink system detected red spots with vis. by all but Ringsdore. Brown saw intense white spot NW of crater wall" NASA catalog weight=5. NASA catalog ID 933. ALPO/BAA weight=4.
M. Cook of Frimley, UK observed a brightening of the crater during this observing session. The cameron 2006 extended catalog ID=346 and weight=3. ALPO/BAA weight=2.
Gassendi 1939 Sep 25 UT 01:30 Observed by Haas (New Mexico? 12" reflector?) "NE part pf c.p. had I=9.4 comp. with I=6.4 (normal? in # 458. under similar obs. cond. (& phase. thus real diff.)" NASA catalog weight=4 (high). NASA catalog ID #462.
Gassendi 1967 Mar 22 UTC 19:39-19:43 Observed by Mosely (Armagh, N. Ireland, 10" refractor, x360) "Red color & blink strongly suspected in small area centred on junction of 3 clefts 1/2 way from c.p. & ESE wall. Well-defined & did not note change during obs. period. Clouds terminated obs. till 2120 when it was not seen." NASA catalog weight=3 (average). NASA catalog ID #1018.
On 1989 Sep 12 at UT00:58-02:25 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x159, S=7/10) observed similar light conditions to 1989 Jul 15. At 02:00 he observed pink on the south west wall of Aristarchus crater. At 01:24UT the Aristarchus ray was yellowish, however the entire Moon had a grey-yellow tinge of colour. Chromatic aberation was observed at 01:56UT. By comparison Gassendi was checked and had no colour. At 02:10 the crater wall of Aristarchus was unusual and was quite different in appearance to rims of other craters. The cameron 2006 catalog ID=375 and the weight=1. The ALPO/BAA weight=1.
G. Ward (a lunar observer for 15 years) observed an area just south west of Mersenius C to be blurred and in a greenish cloud. The green colour was more like that of dead grass than one gets from a neon bulb. The effect was seen from 04:50-04:57UT, but could have been going on before it was first noted at 04:50-UT. Seeing was 6-7/10 4" Refractor (2 element). refractor had been used hundreds of hours before (over a 10 year period) with no similar colour was seen. The observer checked other areas but did not see any similar effects. They also rotated and changed eyepieces, but this made no difference to the TLP. The TLP site seen was picked up on an image taken earlier at 04:47UT by W. Bailley, from Sewell, NJ, USA. Unfortunately the area concerned, a mountain on the image, was saturated and so we cannot tell if a colour was present there and the seeing was poor.
Aristarchus 1975 Oct 16 UT 20:00? Observed by Foley (Kent, England, 12" reflector) "Deep blue-viol. spot in NW (IAU?) interior corner." NASA catalog weight=3. NASA catalog ID # 1413. ALPO/BAA weight=1.

Ireland (Moore & Mosely) x360 - seeing Fair to Poor) "Red patch seen intermittently; moon-blink from 1916-2047h. Position agreed with Sartory who alerted them to Aris. area; checks on others were neg." NASA catalog weight=5. NASA catalog ID 1020. Then Aristarchus 1967 Mar 23 UT 18:40-20:30, 21:30 by Marsh and Farrant (Cambridge, England, 8" reflector, x330). "Suspected colour on SW (ast.) wall. Farrant saw color in crater, completely independently, (inform. suggests same phenom. as seen by Moore & Moseley tho they said Cobra head). NASA Catalog weight=5. NASA catalog ID # 1021. ALPO/BAA weight=3.

Mersenius 1975 Jun 21 UT 21:50-22:45 Observed by McConnell (Northern Ireland, 6" reflector) Moore? (Sussex, Enland, 15" reflector, 5" refractor, S=F), Reading (Rushden, England, ? 14" reflector) and Foley (Kent, England, 12" reflector, S=P) "McConnell saw an obscur. starting at 2150h which disappeared at 2245h. Moore(?) alreted, saw no anomaly in 15 in refl. & 5-in refr. under fair conditions from 2209-2228h. Reading reported neg. fr. 2250-2345h (after phenom.). Foley reported color in it but also a crater to S. of it & Aris., prob. due to seeing conditions." NASA catalog weight=5. NASA catalog ID#1408. ALPO/BAA weight=3.
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.
Aristarchus-Herodotus 1971 Sep 02 UTC 20:00 Observed by Ayeau (Paris, France, 12" reflector, x100) "Brownish-red or maroon seen on Aris. W.wall ridge to Herod. on S.wall of Herodotus" NASA catalog weight=2. NASA catalog ID #1311. ALPO/BAA weight=2.

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 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.
Alphonsus 1966 May 03 UTC 21:30 Observed by Smith (England, 10" reflector) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moonblink) "Reddish patches. Not confirmed by Corralitos MB (but in their report they give the feature as Gassendi)." NASA catalog weight=2. NASA catalog ID #936. ALPO/BAA weight=1.
