On 1964 Jun 29 at UT 07:05-07:33 Bartlett (Baltimore, MD, USA, 4" reflector x240, S=5, T=4) suspected a violet glare? on the EWBS of Aristarchus, but was too faint to be certain.

On 1984 Jul 04 UT 22:08-23:09 Foley (12" reflector, Kent, UK) found that Censorinus gave a low brightness CED reading of 58%, despite all other measured points on the Moon as being normal. M.

On 1984 Jul 04 at UT 22:05-23:09 Richardson (Swinton, Yorkshire, UK, seeing=VE) found that a peak west of Theophilus crater had a deep blue colour, and this was strange because no colour was seen elsewhere on the Moon. Foley (Kent, UK, 12" reflector), once alerted, found a dome east of Kant? to be blue, and likewise no colour was seen elsewhere on the Moon. Cameron 2006 catalog ID=246 and the weight=4. The ALPO/BAA weight=3.
On 1984 Jul 04 UT 22:08-23:09 Foley (12" reflector, Kent, UK) found that Torricelli B was a much lower brightness than was expected and this remained the case for the rest of the lunation. The Cameron 2006 catalog ID=246 and the weight=4. The ALPO/BAA weight=1.
On 1972 Feb 23 at UT0010-0035 Fornarucci (Garfield, NJ, USA, 6" reflector, x250, seeing=fair and transparency=3.5). Shading usually visible west of it was not seen. Cameon comments that the albedo must have been at 5, where normally it is 4.5 and the nearby plain is 5). Cameron 1978 catalog ID=1322 and weight=2. ALPO/BAA weight=2.
1964 Jul 23 UTC 04:45-06:07 Observed by Bartlett (Baltimore, MD, USA, 5" reflector, x180, S=1-4, T=3) "S.region of floor was granulated & rated 6deg bright, rest of crater 8deg.

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.

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.
