On 2001 Jun 29 at UT22:16-22:22 C. Brook (Plymouth, UK, 60mm refractor, x120, no spurious colour seen, seeing I) observed that the central peaks of Alphonsus looked bright at 22:16UT but had dimmed by 22:22UT.

On 2001 Jun 29 at UT 22:16-22:20 C. Brook (Plymouth, UK, seeing conditions very good, x120) reported that the central peak of Alphonsus was brighter than the central peak of Arzachel (or was it the other way around?). Cook observed 4 hours later from Washington DC, USA and found that on CCD images that the central peak of Alphonsus was only slightly less than that of Arzachel. The ALPO/BAA weight=2.
On 1964 Jun 21 at UT 21:18 Lipskii and Pospergelis (Shternberg State Ast. Institute, AZI-2" reflector (Cass.) observed Aristarchus: "Polarization meas. with electron polarimeter. Plane of polariz. rotated 2deg fr. the adjacent areas. They interpret it as some scattering medium over the crater. (Source gave date as 6/31/64, misprint =21st?)". The Cameron 1978 catalog ID=820 and weight=5. The ALPO/BAA weight=4.
On 1960 Sep 04 at UT00:00? Miranova (Russia or Israel) observed a TLP at an unnamed lunar feature: "Spectral photom. of some lunar obj. in 4250, > 5000A bands. Spectral plates". Cameron suspects luminescence? The Cameron 1978 catalog ID=730 and weight=5. The ALPO/BAA weight=1.
During an eclipse of the Moon the crater appeared normal until it emerged from the shadow. In the north east the dark floor was not its normal hue and two light areas appeared to join. The emerging patches became less and less bright, finally disappearing at 0345 UT when the crater returned to normal. Cameron 2006 catalog extension ID=10 and weight=2. ALPO/BAA weight=2.
Bright spot (4th magnitude) seen on eclipsed Moon and glimmering specks. Seen by nephew and neice of Beccaria. Cameron 1978 catalog weight=4. ALPO/BAA catalog weight=2.
On 1877 Aug 23/24 at UT 23:10-01:00 Airy, Pratt and Capron (Greenwich, England, France) observed during a lunar eclipse an unusual spectrum with strong absorption in yellow. (Airy) 2 patches of crimson light of short duration. Cameron says that this is a confirmation observation and that Airy was the Astronomer Royal. The cameron 1978 catalog ID=197 and weight=5. The ALPO/BAA weight=4.

On 1964 Jun 25 at UT ~01:07 Rubens de Azevedo (Brazil) observed a white streak from Grimaldi on the limb, during an eclipse. The Cameron 1978 catalog ID=822 and weight=4. The ALPO/BAA weight=2.
On 1964 Dec 19 at UT 01:55 A.R.Taylor (London, UK) suspected a brief pinpoint of light near Janssen (unconfirmed). The ALPO/BAA weight=1.
On 1964 Jun 25 at UT ~01:07 Titulaer (Utrecht, the Netherlands) observed that Aristarchus crater was very bright during an eclipse. The Cameron 1978 catalog ID=822 and weight=4. The ALPO/BAA weight=1.
On 1905 at Feb 19 at UT 18:00-19:03 Moye (Montpelier, France) observed Aristarchus shining as a star in the dark, during a lunar eclipse. The Cameron 1978 catalog ID=320 and he weight=3. The ALPO/BAA weight=3. The ALPO/BAA weight=2.
In 1950 Apr 02 at UT 20:00 Chernov (Russia) observed two dark spots in Atlas during a penumbral phase of a lunar eclipse to quickly darken and become sharp in detail. The cameron 1978 catalog ID=524 and weight=1. The ALPO/BAA weight=1.
On 1968 Apr 13 at UT05:00-05:45 Cameron and Laczo (Greenbelt, MD, USA, 6" refractor, x50, 36" reflector x400, 12" reflector x80, seeing= excellent) observed for the folliwing craters: Aristarchus, Pytheas, Euler?, Censorinus, Plinius?, Proclus, Menelaus, Manilius: "Star-like pts. in the craters. Only Aris. identified certainly, rest fairly certain except Euler & Plinius. Seen in 6-in refr. at 50x but not in 36-in refl. at 400x where they were bright, but not star-lie pts. Seen later in 12-in refl. at 80x. In another bldg. Seen 1st @ 1/2h before totality ended, but not earlier dur. tot. tho't by author (WSC) to be geom. & instrumental = power effect". Chilton, K.E. reports in RASCJ that another observer did not report any of what the Greenbelt observers saw at all?The Cameron 1978 catalog ID=1065 and weight=4. The ALPO/BAA weight=1.
Proclus 1938 Nov 08 UTC 20:00 Observed by Green (England? Seeing = good) "2 bright spots in Schmidt & Wilkins' craterlets. Was struck by whitish aspect of parts of floor -- possibly mists. S.wall concealed by these strong white patches, as if breached ring." NASA catalog weight=3 (average). NASA catalog ID #443.
