Colour confirmed by Foley. Fitton may also have been observing. At 22:00 A.C. Cook observed and commented that a darkish, perhaps brown-orange colour seen - but suspected it was probably spurious colour - but by now the seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of several features, including Theophilus, had not noticed anything unusual 18:50-19:10.

On 1976 Feb 14 at UT23:35-0053 LeCroy (Springfield, VA, USA, 4.5" reflector, x75, S=6 and T=4.5). A blue haze was seen on the east side of Aristarchus and red haze on the west side. At 00:00UT details were more clear and at 00:24UT Aristarchus and Herodotus, were seperated. At 00:34UT colours were gone. At 00:35UT blue was on Aristarchus and the area was bright, but was black in a red filter. At 00:53UT the features were clear and the colour gone and the brightness had decreased to 9. Cameron comments that the colour was not due to temp. inversion because of being dark in the red filter, implying a medium). The Cameron 1978 catalog TLP ID is 1428 and the weight=1. This is an ALPO report. The ALPO/BAA weight=1.
On 1985 Sep 28 UTC 20:54-23:52 P.W. Foley (Suffolk, UK) found (actually before 20:54 UT) brightness variance in Torricelli B. J.D. Cook (Frimley, UK) observed a brief blue coloured patch somewhere in the Torricelli B region, but could not pin it down precisely. At 22:50UT M.C. Cook (Frimley, UK, 30cm reflector, seeing III - occasionally V, transparency moderate to good) Found the crater to have an elongated appearance (in SSW-NNE direction) in white light, similar to the previous night. A bright elongated spot was seen on the NNE floor, close to where the wall should be. Not able to define the rim. There was a very dark surrounding area to the crater, similar to what it was on the previous night (roughly 1/4 brightness of Censorinus). 23:04UT brighter in yellow, then red, then blue. At 23:10 it was seen that blue filter dulled the crater - this was odd because both Censorinus and Proclus were brighter in blue, which is what he would normally expect. At23:15 UT Censorinus was brighter in blue, then yellow then red filters and some orange spurious colour seen to the south of Censorinus. At 23:23UT no spurious colour seen on Proclus or Censorinus. 23:46UT Torricelli B elongated as before, but a very faint ray might have been seen to the south west of the rim. This report is not in the 2006 Cameron catalog. The ALPO/BAA weight=3.
On 1996 Dec 24/25 at 18:12-00:02UT P. Moore (Selsey, UK, using a 15" reflector x250-360, and seeing III) saw a strong orange colour on the south wall and floor of Aristarchus. He suspected it to be spurious colour but could not detect colours on any other craters. The colour remained but at 18:12 UT he suspected a trace on colour on Mons Pico but was not sure. However he reported it to the TLP coordinator of the BAA Lunar Section. The orange in Aristarchus gradually faded and had almost vanished by 00:20UT when seeing was too bad to continue observing. At 02:30UT he was able to re-observe again and there was still a very very slight hint of orange in Aristarchus - but he comments that if he had not been looking for it he might not have noticed. ALPO/BAA weight=2.
Plato 1966 Aug 01 UT 06:14 Observed by Kelsey (Riverside, CA, USA, 8" reflector x300) The wall from the S to the NNE wouldn't focus well though at least 4 craterlets on the floor were clearly seen (Ricker uncertain if real TLP.

Aristarchus 1987 June 14 UT 04:43-08:00 Observed by Curtis, Jacobs, and Manske (Yanna Research Station, Carl A. Fosmark Jr. Memorial Observatory, Madison Astronomical Society, WI, USA, 17" f4.5 Dobsonian and the 8" f10 SCT Celestron) "On the night 13/14 June 11:42 P.M. to 3:00 A.M. local time or 14 June 04:43 to 8:00 UT. Three people witnessed this event and all three of them observed with three different telescopes to rule out instrumental aberration. These three pople were members of the Madison Astronomical. The three observers involved are Keith Curtis, Tom Jacobs and Robert Manske. Keith Curtis took detailed notes of the event as he observed it. The observations were made at the Yanna Research Station, Carl A. Fosmark Jr. Memorial Observatory of the Madison Astronomical Society following the annual picnic. This is MAS dark sky site and is located near Brooklyn, Wisconsin. As they were observing the night sky they saw the Moon rising and noted a strong orange color due to atmospheric effects. Approximately 1/2 hour after the Moon rise they decided to turn one of the telescopes on it. It was at 04:43 UT, it was noted by Keith Curtis that as the Moon rose it began to loose the horizon color effect and return to its normal color, but he found that the red color was not leaving the crater Aristarchus. At first they all thought this was an atmospheric effect but decided it was a real event since they detected a second crater (Euler) showing red color on its rim. Keith Curtis said that the red color was very strong on the Western rim of Aristarchus with a strong blue/green or aqua green on the Eastern rim. Keith also reported that the glow opaque enough to prevent viewing of the interior of crater Aristarchus. He said they observed until 3:00 A.M. daylight saving time or 8:00 UT. and the red glow was still visible when they ended their observing session. Robert Manske description of the event was that he saw two craters glowing a strong red and blue giving it a rainbow effect. He said that the red glow was so strong he was unable to see the craters underneath during the entire observing session. Concerning the orientation of the red and blue was on the crater he stated that he did not remember since he failed to take any notes. Concerning whether there was any difference in appearance when they observed it with the 17" f4.5 Dobsonian and the 8" f10 SCT Celestron. He said that he could not detect any difference to the lunar formation or the color on it regardless of which telescope he used. He did mention that as the Moon was rising it had the appearance of one large Maria in the center of the disk. This illusion disappeared as the Moon rose higher into the sky. When talking to Tom Jacobs he said that he remembered that he did not see anything on the Moon until 1/2 hour after Moon rise. He said that he remembered that the entire Aristarchus region had a strong reddish or pinkish color. All three witness all reported variations in the type of color they were seeing. This would indicate that individuals color perception is a major factor during a color event. Keith Curtis saw a very strong coloration around the rim of the craters, where Robert Manske saw the entire region covered by this red and blue coloration and he could not see the interior of the craters underneath. Tom Jacobs reported that the glow covered the entire crater but he could see the crater underneath it. The Moon never achieved a height greater than 21 degrees so it could be that what the observers saw was caused by the Earths atmosphere.

Torricelli B 2002 Oct 23/24 UT 23:25-23:52 Observed by Clive Brook (Plymouth, UK, 60 mm OG x120 + prism) "Observed that Torricelli was very diffuse and Tor B showing shadow ? observer considered a shadow perhaps a little surprising this far from the terminator. Nothing unusual seen by M.Cook at 23:52UT or by A Cook at 00:40-00:52 and indeed other craters did appear to have shadows this far from the terminator ? so perhaps only unusual aspect of the original observation that could not be checked due to poor seeing by the latter observer was the fuzziness. The ALPO/BAA weight=1.
In 1790 Mar 03 at 22:00 UT Wilkins (England?) observed Herschel's 1787 lumninous point (Aristarchus) in the same place. The Cameron 1978 catalog ID=67 and weight=4. The ALPO/BAA weight=2.

On 1981 Oct 26 UT 20:44-21:14 M. Mobberley (Bury St Edmunds, UK, 14" Cassegrain, seeing III) noticed an ~100deg wide fan on the floor of Theophius, radiating on the central peak upto the surrounding base of the wall next to Cyrillus crater. This fan had a hint of yellow/red. The observer did not consider this to be abnormal - there was certainly no loss of focus here as far as the observer was concerned, and no mention is made of this effect in later observations that night. Plenty of spurious colour was reported. The ALPO/BAA weight=1.

Aristarchus darker in red light. all other craters were normal in red. Attempts to change the eyepiece did not make any difference to the blue colour. Cameron 2005 catalog ID=43 and weight=4. ALPO/BAA weight=3.
Gassendi 1971 Jun 13 UT 07:22-08:05 Observed by Raimundo Nonato da Silva (Parnaiba, Brazil, 9.5" reflector, x180) "At 0755h variation on W.(IAU?) edge of crater "brightness seemed to become a little darker" as it was gugacious (foggy?), Was not sure it was a LTP. Other features & it were normal from 0658- 0755h". NASA catalog weight=1. NASA catalog ID 1295. ALPO/BAA weight=1.
On 1979 Nov 09 at 10:30-11:05UT D. Louderback (South Bend, WA, USA, S= 4-2/10, T=P) detected a rapid fade in brightness of south and north sunlit slopes of Mons Piton. Then the western flank faded and became obscured in detail. The variations detected were approximately 5 sec in duration, where as seeing effects were of the order of 15 sec. Mons Pico and other mountains did not show a similar effect. "It was seen only in viol. filter tho once seemed blurred in red. No changes, dimming was like a veil of mist covering the mtn - swiftly, then dissipating as rapidly. Sketch. Phenomenon went on & off till 11:00UT. Cloud was cir. In viol & spreadover mtn in 2s. Saw 6 rapid, spinning motions within the cloud like an explosion or tornado seen from above. Blurring in red was more elongated. Motion across it was like a heat wave. Whole event lasted ~35m but disappeared in a few secs. Albedos 7.4 cp, 7.5 pt A, 7 pt B." Cameron 2005 catalog ID=75 and weight=4. ALPO/BAA weight=3.

On 1981 Oct 18 UT 22:14022:16 M.Mobberley (Bury St Edmunds, UK, 14" Cassegrain, seeing variable, transparency misty) found that the central craterlet on the floor of Plato was not visible, despite it being visible under similar colongitudes on other nights. Might be due to observing conditions, but observer suspicous. At 02:08 the observer comments that the central craterlet was ellusive, and at 02:42, though it is uncertain whether they regarded it as suspicous still at this stage? ALPO/BAA weight=1.
