"Attention distracted from Ptolemaeus to Klein where floor was
not normal. It had a pink line at foot of inner N. wall which
was bright in sunlight. Pink extended from N. to W. pt. Floor in
NW quad. was reddish-brown. All similarly illum. craters were
examined & no trace. Klein shifted to all parts of lens but
color persisted, but could not be induced in other craters. At
2230h floor took on more color in NW. In filters floor detail
vis. in red, almost invis. in blue, c.p. barely vis. Color
bright in red, & black in blue filter. In white light looked
like atm. above surface. Ptol. was equal in red & blue, & also
other craters. All seemed normal again on May 2nd. (date in ref.

On 1982 Oct 22 at UT23:45-00:10 K. Marshall (Medellin,
Columbia) found the W-NW rim of Proclus was both red and very
bright. The brightness is normal, but as no similar colour
effect was seen elsewhere on the Moon, this was regarded as a
TLP. The Cameron 2006 catalog ID=187 and the weight=3. The

variations of brilliancy along the dark limb reembled light of a moving

they were same cause on the Moon. The effect was brighter two days

On 2009 Mar 31 at UT 19:26-19:50 Cook M.C. (Mundesley, UK,
90mm Questar reflector, x130, seeing II-III, transparency poor
to moderate). The crater had it's north-east to west wall
illuminated and a central feature on the floor, faintly seen -
both of these are normal. The crater itself though was much
brighter in a red filter, bright in a wellow filter, but dull
in a blue filter. Possible variation seen whilst using the red
filter, but this may have been due to haze. All other features
behaved normally. The ALPO/BAA weight=3.

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.

Eimmart 1913 Apr 14 UT 01:00 Observed by Pickering (Mandeville,

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
weight=4. The ALPO/BAA weight=1.
