On 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a darkening in the Cobra Head, Schroter's valley area of Aristarchus - the best example that he had ever seen. The Cameron 2006 catalog ID=474 and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section circular 1995 Oct, p125 and personal communication from David Darling to the BAA on 6/6/1995. Note it is uncertain whether this refers to the Clementine mission or to somebody who observed during the Clementine mission, or somebody with that surname. Anyway if it is the Clementine mission then the date is wrong - possibly the year should have been 1994? The Cameron catalogue does actually mention a TIFF on Clementine mission? The Cameron 2006 catalog ID=474 and the weight=3. I am assuming that the year should be 1994 and not 1995? The ALPO/BAA catalog weight=1 until we can find out what the correct date is?

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.

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.
Aristarchus 1970 Apr 23 UTC 07:00 Observed by Thomas
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.

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.

Proclus 2001 Nov 04 UTC 07:00-07:43 "Robin Gray of Winneucca, Nevada, U.S.A. reported a contrast effect and brightening in the crater Proclus. 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.

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.

Theophilus 1965 Jul 18 UTC 08:52-09:01 Observed by Cross, Ariola (Whittler, CA, USA, 19" reflector, x450, S=4, T=3) "Red spots; ruby red within a pink area on c.p." NASA catalog weight=5. NASA catalog ID #885. ALPO/BAA weight=4.
Alphonsus 2002 Sep 27 UT 00:00-02:15 Observed by Clive Brook (Plymouth, UK) "Central peak was bright 00:00 UT but had faded by at least 2 deg on the Schroter scale - no colour seen. Observer continued observing until 02:15 UT but central peak had dimmed considerably by then"
Aristarchus 1964 Aug 28 UT 04:30-04:50 Observed by Bartlett (Baltimore, MD, USA, 4" reflector x240) "Faint blue-viol. radiance on EWBS; dark viol. on nimbus. S.floor dull, 6, granulated, distinct yellow-brown; rest of crater 8 bright. NASA catalog weight=4. NASA catalog ID #847. ALPO/BAA weight=2.
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.
On 1982 Oct 08 at UT 04:15-04:30 W. Cameron (Silverspring, MD, USA, 3.5" reflector, x160, Seeing-very good) suspected blue tinge on north west rim and brown/red on south east rim of Aristarchus crater + focus was slightly difficult. No similar colour effect seen on other craters. Cameron 2006 catalog ID=186 and weight=1. ALPO/BAA weight=1.
On 1982 Oct 08 at UT 04:15-04:30 W. Cameron (Silverspring, MD, USA, 3.5" reflector, x160) found that Clavius had a "D" shaped crater on its outskirts that made it appear to have a ridge crossing through it. Cameron 2006 catalog ID=186 and weight=1. ALPO/BAA weight=1.
