In 1920 Feb 23 at UT 21:00? an Unknown observer saw peaks on the south cusp were like a string of perls elongating the cusp. Lines drawn through Stoffler and Curtiunto(?) limb gives position. The Cameron 1978 catalog ID=376a and weight=0. The ALPO/BAA weight=1.
On 1969 Jul 18 at UT 23:00-00:15 Ronaldo R. de F. Mourao (Rio de Janeiro, Brazil, 8" refractor, 10" refractor(?), 19.5" refractor) saw a TLP in Aristarchus that they had seen earlier in the evening involving: Luminosity in Aris. strong & prolonged northward with impression of 2 lum. pts. (Apollo 11 watch). The Cameron 1978 catalog ID 1159 and weight=4. The ALPO/BAA weight=1.
On 1989 May 10 at UT02:30-03:50 M. Wisniewski (Chicago, IL, USA, 8" & 6" reflector, x123) found Aristachus to be unusually bright and "glowing" as a blue-white magnitude 8 disk, though it faded close to the end of his observing period (02:30-02:50). A ray from Tycho could be seen in the direction toards Aristarchus crater. Darling (Sun Praire, WI, USA, 12.5" reflector, x50) found Aristarchus Z to be both bright and diffuse. The Cameron 2006 catalog ID=363 and the weight=2. The ALPO/BAA weight=1.
On 1989 May 10 at UT01:54 D. Weier (Sun Praisre, WI, 12.5" reflector, x50?) detected a flash east of Grimaldi crater "like a small electrostatic charge - radiated out like a decorative plasma lamp - not fuzzy. Darling (Sun Praisre, WI, 12.5" reflector, x50?) saw it but dismissed it as he had seen it many times before (in same loc?). The Cameron 2006 catalog ID=363 and the weight=2. The ALPO/BAA weight=2.
On 1994 Jan 16 at UT19:30-21:10 D. Strachen (England, UK, 4" refractor, x21 and x143) whist looking at an occultation of ZC3453, saw a bright spot in Earthsine, just north of Aristarchus (47W, 25N) at position angle 30deg-40deg, only a little way in from the limb. It appeared like a star through haze and a few seconds of arc in diameter. It was Visible for more than 1 hour until 20:50UT although had faded somewhat by that time. However J. & M. Cook (Frimley, UK, 12" reflector, x143 and x244) saw nothing in Earthshine from UT 20:02-21:10. The Cameron 2006 catalog ID=472 and weight=1. The ALPO/BAA weight=1.
Cape Agarum 1995 Feb 05 UTC 18:10-19:20 Observer: P.Moore (Sussex, UK, 15" reflector) - obscuration seen - Antoniadi II seeing, and Moon high up. BAA Lunar Section report. ALPO/BAA weight=3.
Alphonsus area? 1949 Jun 01 UT 22:06 H.P. Wilkins (Kent, UK, 6" reflector x200) observed a bright white 1 sec stationary (mag 3?) flash in Earthhsine, close to the central meridian, and due E of Theophilus (potentially in the general area of Alphonsus?). The flash was approximately 6 km in diameter. ALPO/BAA weight=1.
On 1970 Apr 11 at UT 22:04-23:00 Claudio Pamplona and Jackson Barbosa(Fortaleza, Brazil, 2" refractor, x160, seeing=fair) observed an obscuration over Peirce, in particular they could not see the crater wall and the crater itself was like a black pit. (Apollo 13 watch). The Cameron 1978 catalog ID=1238 and weight=1. The ALPO/BAA weight=1.
On 1969 Jul 20 at 22:50-23:15UT Jean Nicolini (Sao Paulo, Brazil, 12" reflector x430, S=II.5-III.5) saw a weak reddish area on the north west(east?) wall of Eudoxus crater. An English Moon Blink device showed it dark in blue and opaque in red. Reddening remained unchanged while comparing it to adjacent region and Aristotles. Colour index was toward dirty orange. Colour most apparent in the good moments of seeing and disappeared in the poorer moments of seeing, Cameron says that this is opposite to what was expected if the effect was atmospheric in origin and no colour was seen in Aristotles. Apollo 11 watch. Cameron 1978 catalog ID=1177 and weight=3. The ALPO/BAA weight=3.
On 1970 Apr 12 at UT 22:10-22:40 Censorinus was observed by Jean Nicolini (Sao Paulo, Brazil, 12" reflector, x680). The crater had a visible reddish hue--gap in bright area on western slope. Colourless to pink to reddish. Environs also involved. Photographs were taken. (Apollo 13 watch). Cameron 1978 catalog TLP ID 1241 and weight=3. ALPO/BAA weight=3.
2005 Jul 13 UT 01:18 W.Watson (USA, East coast, transparancy: heavy hazy cirrus, and the only other object visible was Jupiter) observed a naked eye flash on the Moon in the northern hemisphere, with a magnitude of -3 to -4. The ALPO/BAA weight=1.
Proclus 2005 Jun 13 UT 16:00-17:10 Observed by Julio Lobo (Campinas, Brazil, 500mm telescope + finder scope) "Glow and reddishness (pink) seen on circular rim. Also crater was intensely bright all over. After 16:30 the brightness fades, returning to normal. The ALPO/BAA weight=3.
Piton 1970 Apr 13 UT 22:06-01:30 Observed by Cutts (Waverton, UK) "Peak was bright (Apollo 13 watch. Shining in dark?)" NASA catalog weight=1. NASA catalog ID #1247. Similar illumination shown on Hatfield Plate 2E(left). ALPO/BAA weight=1.
