(Denmark, 36" refractor, 60, 200x, seeing good) "Dark reddish
spot in SW part of crater. At 60x. Became clearer at 200x &
seen in midwest also. At 0331h phenom. clearest in west, while
S. region had faded. Air turb. & dawn ended obs. at 0331h.
Seen best in yellow filter, well in red, invis. in green &
blue." NASA catalog weight=3. NASA catalog ID #1298. ALPO/BAA
weight=3.
On 1989 Jun 28 at UT 08:39-09:00 D. Darling (Sun Praire, WI, USA,
3" refractor, x36) discovered that at this time Mons La Hire was the
brightest feature on the Moon. LaPrice was also very bright. Cameron
quotes that Darling recorded that LaHire had a brightness of 7.0 and
LaPlace=7.5. Darling did not think that this was a TLP. The Cameron
2006 catalog ID=369 and weight=0. The ALPO/BAA weight=1.
On 1989 Jun 28 at UT 08:39--9:00 D. Darling (Sunpraire, WI, USA, 3"
refractor, x36) noted that promontorium LaPlace was very bright.
LaHire brigtness was 7.0 and LaPlace was 7.5. Darling suspects
that this was not a TLP because "as did not have mother-of-perl
appearance as seen on Piton at times"The Cameron 1978 catalog ID=369
and the weight=0. The ALPO/BAA weight=1.
On 1982 Oct 22 at UT23:55 K. Marshall (Medellin, Columbia) found
the NE cleft in Posidonius to be abnormally bright, much more so
than the walls of the crater. The ALPO/BAA weight=1.
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
ALPO/BAA weight=3.

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.
