Crisium. There was one on the north and the other two in the south west
to south. They lasted approximately 30 minutes and then promptly
vanished. Cameron says that it cannot be this date because the Moon was
not visible at 17:00UT Suggests 05:00-05:30UT? The Cameron 2006 catalog

On 1978 Jan 06 at UT 01:00 Anorati (Firenze, Italy) observed inside a

not suspect that it was a meteor, but instead produced by an
intelligent being????? Cameron suggests a terrestrial meteor?

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.

pink in colour on the edge of its wall. The effect lasted from 01:15-
01:44UT and he could discern the terrace on the western wall.
Comparisons were made to Tycho and Copernicus - all of which were

Tycho 1940 Dec 09 UTC 04:00? Observer Barcroft (Madera, CA, USA). The

Campanus 2014 Jan 11 UT 22:00-22:30 S.Bush (UK, 6" SCT, x180,
seeing average) made a sketch of the Campanus and Mercator
craters. He found that the central peak of Campanus difficult
to resolve and the floors of both craters were devoid of
detail. Mercator was the lighter shade of the two floors.
Earlier at 19:47 UT M.Brown (Huntingdon, UK) imaged this
region and using Registax resolved details on the floors of
both craters, though Mercator clearly was slightly lighter in
floor shade and had less detail on its floor than Campanus.
The most likely explanation was that it was just seeing
effects blocking the visibility of detail - this of course is
less of a problem for a Registax usid on the CCD image.
However just to be sure this observation is being given an
ALPO/BAA TLP weight of 1, to encourage visual observers to
attempt this observation under similar illumination and
seeing.
On 1983 Aug 19 at UT 07:15-07:30 D. Louderback (South Bend, WA, USA,
3" refractor, x150) found that the direct sunlit side of Mons Piton
mountain (E) was brighter than (his designated) points C and D and this
happened at the same time as some "blurring"at 07:15UT. The darker
side, between C, A and B were not so dark through a red filter as
through a blue filter (this was the opposite of what had been seen
before at a high sun angle). Louderback suspects that there had been a
colour change since he last observed. He also noted that in red light
the whole lunar disk appeared fuzzy and out of focus. Louderback noted
a 1 sec brightness on the east slope and the whole mountain sharp in
blue light. The Moon's altitude was low though. Brightness measurements
were 4 in blue light and >= 4.6 in red light and "so illdefined almost
blended into plain". Cameon commnets that a telescope colour/focussing
issue may have been at work here! The Cameron 2006 catalog ID=226 and

At the start of the observation, the NE wall and immediate

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.
