On 1988 Apr 21 at UT 01:28-04:00 D. Fryback (Madison, WI, USA) took a series of photographs - Aristarchus was a luminous patch and in one photograph a red spot (Cameron suspects marks on the film). is seen near Aristarchus. Strangely though when looking through the telescope, the crater was not excessively bright. D. Spain (Fairdale, KY, USA, 3.5" reflector?, x60) observed a narrow white streak of mag 5-6 of duration 0.5 sec that covered 160-320km near the centre of the Moon at 01:53UT.

On 1871 Nov 20 at UT 17:30-19:30 H. Pratt (UK) saw one of the most spectacular TLP obscurations that he had ever seen in Mare Frigoras. He observed a kind of haze around the north west (NE?) slopes of Plato. This effect was not seen elsewhere and all objects in Mare Frigoris were indistinct or veiled. By 18:30 the effect was modified and by 19:30 very little trace was seen. Ref. from Corliss.
Knopp of Paysandu, Uruguay on 1885 Feb 22 at 23:00-23:30? UT saw a definite light, looking like Saturn in Cassini?. The previous night he had seen red patches in the crater. Cameron's 1978 catalog ID=348 and weight=4. ALPO/BAA weight=3.
Plato 1895 May 02 UT 20:45, 23:45 Observed by Brenner and Fauth (Germany?) "Streaks of light (Brenner) bright parallel bands in center Fauth (indep. confirmation?)." NASA catalog weight=5. NASA catalog ID #284. ALPO/BAA weight=1.
Plato 1972 Jun 19 UT 21:40-22:30 Observed by S.A. Jones (Swansea, Wales, 12" reflector x150) and Moore (Selsey, England, 12.5" reflector x450) "Noted a bright area in the center.

Plato 1887 Feb 01 UT 18:00 Observed by Elger (England) "Ill-defined shadow of peaks of W.border-in contrast to sharpness of mts. outside it. Never seen before.

On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector, seeing II-III) noted that the south wall of Plato at the 11 o'clock position, at the location of a cleft, was fuzzy on either side of the cleft. There was also a deep red colour along the cleft and the outside wall. The colour had gone by 22:40 though. All other parts of the rim of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III) sketched some obscurations at 22:03UT. At 22:08UT the red colour reduced to a red line and vanished by 22:37. The south wall obscuration varied in size and there was a possible obscuration at the 7 o'clock position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and M.Cook's observations. Detail inside the crater was sharp, but colour oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km away had atmospheric ripples affecting his observations. At 21:36UT G. North described the south wall as odd in appearance and the terrain south of this was lacking in detail - this was odd because elsewhere Plato was nice and sharp. At 21:45UT though the north section of the crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5. The ALPO/BAA weight=3.
On 1938 Jan 16 at UT 00:00 Barker (Chestnut, England, UK, 12.5" reflector) noticed that Plato crater had a brownish-gold veined surface, colour irregular - laid on a smooth floor. The Cameron 1978 catalog ID=430 and weight=3. The ALPO/BAA weight=2.

Craters B & J to SE had faded, vanished at 0630. Hazy patch remained around peak, alpha low mainly to NE like a comet's tail. Slightly reddish fringe to E wall. (shown in sketch)". The above has been quoted in full from the Cmeron catalog because the catalog desription is slightly ambiguous and any attempted summary might make the description more unreliable. The cameron 2006 catalog ID=470 and the weight=3. The ALPO/BAA weight=2.
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.

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?

Wilkins (Kent, UK, 8.52" reflector) observed that central craterlet in Plato was unusually bright and shows up as a bright white spot on his sketch - though this might have been artistic license in his sketch.

During an occultation of lambda Geminorum on the eastern limb the light from the star took 3 seconds to fade. Cameron 2006 catalog extension ID=8 and weight=2. ALPO/BAA weight=1.
On 1987 Oct 28 at UT 05:05 G. Hewick (UK) observed a 1 sec duration flash on the lunar surface (night side) whilst waiting to observe a lunar occultation of X17959. The colour was yellow and the brightness was approximately magnitude 1 - there was no movement. The location of the flare was between Daws and Vitruvius (17N, 29E).
James Short, Dr Harris and Mr Stephens saw initially a streak of light on the shadowed floor of Plato. They were not expecting to see any light to reach the floor. Shortly afterwards they saw a second streak of light parallel to the first and this shortly divided into two. Gaps in the mountains were found for both streaks, but they were unable to understand why one of the streaks divided into two. Cameron's 1978 assigns this TLP an ID of 20 and a weight of 5. The ALPO/BAA catalog assigns a weight of 1.
