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.

On 1975 Mar 04 at UT03:46-06:01 P.W.Foley (Wilmington, Dartford,
Kent, UK, 12" reflector) observed bluesness along the southern
wall of Plato. This is a BAA observation. The Cameron 1978
catalogue ID is #1403 and has a weight of 1. The ALPO/BAA
weight=1.
On 1975 Mar 04 UT 04:01-05:30 P.W. Foley (Wilmington, Dartford, Kent,
UK, 12" reflector, seeing excellent, no turbulence, slight frost and
mist) had a suspicion of blue on the entire north wall of Aristarchus
crater - not seen visually but detected with a Moon Blink device.
Crater extremely bright and unable to penetrate it visually.
Surrounding areas charp. No red/orange on south wall. All other areas
proved negative. Photographs taken. No change in appearance over this
time. ALPO/BAA weight=2.
Triesnecker 1966 Jul 10 UTC 02:00-02:15 Observed by Allen (Cambridge,

In 1930 Sep 15 at UT00:00 Vasilev (Russia) observed the following in
Alphonsus crater: "During SS there was a triangular spot nr. W. wall
until merging with shad. of wall (normal?) (date wrong as age is 3.2d &
should be @ 23d. 9/15/30 would be correct: aux. data for 15th". The
Cameron 1978 catalog ID=0. The Cameron 1978 catalog ID=398 and
weight=0. The ALPO/BAA weight=1.
Aristarchus 1970 Jul 26 UT 15:00? Observed by Sekiyuchi (Tokyo, Japan,
36" reflector) "Polarimetric and photoeletric anomalies on Moon" NASA
catalog weight=5. NASA catalog ID #1268. ALPO/BAA weight=5.
Aristarchus 1965 Oct 18 UTC 07:30-07:36 Observed by George, Dervas
(Huntsville, Alabama, 20" reflector x125) "Color with intermittent
displays, detected with Trident MB device. Observers dubious. NASA
catalog weight=2 (low). NASA catalog ID #907.
Copernicus 1955 May 15 UTC 03:30 Observed by Firsoff (Somerset, UK,
6.5" reflector x70) "Almost as bright in violet filter as Aristarchus"
NASA catalog weight=4. NASA catalog ID #592.
1965 Aug 21 UTC 06:55-08:05 Observed by Gilheany, Johnson, Segerstrom
(Port Tobacoo, MD, USA) described in the NASA catalog as: "Color patch
detected by Trident; MB device. Color was pink. Astronauts on Gemini 5
saw terrestrial auroras from space on this date". 16" reflector used.
NASA catalog weight=5 (very high). NASA catalog ID No.#890.
Aristarchus 1983 Aug 03 UT 0305-0400 Observed by R,Moseley
(Coventry, UK, 6" reflector, seeing II, Transparency very good).
At the start of the observation, the NE wall and immediate
exterior was the brightest area visible (this is normal) and
seemed tinged with a faint blue/violet. At 03:45 the impression
of colour was fading in the brightening sky, but by 03:55 the
colour was back again with a faint violet/purple surrounding the
whole formation from E clockwise to N. The observer found it
difficult to decide whether it was really a colour on the Moon,
or an optical illusion. ALPO/BAA weight=1.
