On 1971 Jun 16 at UT 07:08-07:09 Raimundo Nonato da Silva
(Parnaiba, PI, Brazil, 9.5" reflector, x90, seeing=good)
observed during a lunar eclipse that the Straight Wall
surroundings were darker than an observation from two days
earlier. At 07:09UT tonality became clearer. As dawn was in
progress and atmospheric turbulence, not sure if it was a TLP?
Other features were normal. The Cameron 1978 catalog ID=1297 and
weight=1. The ALPO/BAA weight=1.
Grimaldi 1938 Mar 28 UTC 09:30 Observer: Firsoff (Glastonbury, UK - 6"
reflector) - Slight greenish colour - {Note the UTC given in the NASA
catalog is 09:30 which is in daylight here in the UK - possibly the
catalog is wrong, else the observer was observing in daylight, but
worth checking out just in case}. NASA catalog ID No. #433 and NASA
weight=4 (good).
Southern cusp obseved by H.Hill (UK) on 1984 Jul 25. Solar
Selenographic colongitude=232.6. Observer noted a dusky ill-
defined strip in Earthshine extending beyond the southern cusp
that appeared "atmospheric". Note that this is almost certianly
not a TLP but is worth checking out if the libration and solar
colongitude is similar, just to verify that this is what the Moon
normally looks like. ALPO/BAA weight=1.
In 1920 Mar 22 at UT 17:00? an unknown observer in England noted an

On 1877 Jun 15 at UT 20:00 Birt (England, UK) observed a bright spot
east of Picard. The reason why this was regarded as a TLP, accoridng to
Cameron was that it was supposed to be faint or invisible. The Cameron

On 1983 Sep 11 at UT 23:52 K.P. Marshall (Columbia, 12"
reflector, x268, seeing II), whilst sketching the crater
Janssen noticed a tenuous red patch on the southern junction
of the valley which joins Fabricius to A. Nothing resembling
this found on nearby areas. The ALPO/BAA weight=1.
On 2010Apr18 at UT 20:45-21:00 P. Grego (St Dennis, UK, 17"
reflector - first practice run) observed that Aristarchus in
Earthishine was the brightest that he had seen it before. The
effect had faded to normal in the next 15 minutes though. "The
bright spot was initially thought to be part of the wall of
Aristarchus, but on closer examination the spot was probably the
crater’s central peak. At around this time I estimated the
brightness of the peak to be around magnitude 8, but this is a
poor estimate as no suitable comparison stars in the immediate
vicinity of the field of view were to be seen. Aristarchus’
outline was visible, as was a clearly defined sweep of
brightness to its west (presumably the high albedo markings
southeast of Herodotus) and another illuminated area to the
north of Aristarchus (presumably the Vaisala area), and a small
illuminated patch on the eastern flanks of Aristarchus. No other
areas of the Moon in earthshine appeared to be as bright as
these markings, and there were certainly no other clearly-
defined spots as brilliant as the one that lay in Aristarchus. A
watch was kept until 22:00 UT, when the Moon went out of view
behind a tree. During this period it appeared that the spot was
becoming less bright and less clearly-defined, although the
other albedo markings in its vicinity remained visible; this may
have been a consequence of the Moon’s diminishing altitude.

On 1991 Apr 22 at UT 02:03-02:14 D. Darling (Sun Praire, WI, USA,
12.5", x99, seeing 7/10) found, using a red and blue Moonblink
device that Atlas crater gave a blink, the dark spots inside the
crater have a dark nucleus in the blue filter. This effect was
not detected earlier that night. The Cameron 2006 catalog then
says "Atlas normal". The Cameron 2006 catalog ID=424 and the

On 1993 Mar 30 at UT19:35-21:15 J. Knott (England, UK, 8.5" reflector,
x180 and x216, seeing=II and Transparency=good) observed at 19:35 the
central peak of Alphonsus appeared to be extra bright although was
normal later, however the observer suspects that this was a contrast
related and was not confident to send out a TLP alert. The Cameron 2006
catalog ID=458a and 458b and weights=0. The ALPO/BAA weight=1.
Torricelli B 2002 Oct 14 UT 02:58-03:43 Observed by Gray (Winnemucca,
NV, USA, 152mm refractor x114, x305, seeing Antoniadi III, transparency
good) "I was out this morning (2:58-3:43 UT, October 14, 2002)
observing Torricelli B. At 3:17 UT the west sunlit wall of the crater
brightened from an intensity (Elger Scale) of 5.0 to 9.0. In actual
terms it went from slightly less bright than the walls of Picard to as
bright as the sunlit west wall of Dionysius. This was observed at 114x
in white light, where all three craters were in the field of view
simultaneously. This event lasted less than a minute and no comparable
brightening in Dionysius or Picard was seen. The wall of Torricelli B
returned to 5.0 in brightness. I continued to observe Torricelli B in
white light until 3:43 UT, but the brightness remained at 5.0. Before
the brightening I tried blinking Torricelli with the following
combinations of filters: Wratten Red 25 and Blue 38A, Red 25 and Blue
80, and Red 25 and Schott BG38 (Blue Green). Nothing showed up more
prominently in any combination except the Red 25-Blue 38A combination,
where Torricelli B became invisible in the Blue, probably because of
the filter density. Both the Blue 80 and Schott BG 38 seemed closer in
density to the Red 25 than the Blue 38A is. I could not see any details
inside Torricelli B during this session, including the bright spot on
the NE rim." The ALPO/BAA weight=3.
On 2009 Apr 02 at UT 21:45-22:05 C. Brook (Plymouth, UK,
5" refractor, x40 and x100, using red and blue gelatine
Edmund Optics filters (rose No. 47 and blue No. 80),
transparency poor due to thick haze. seeing was excellent)
observed that that the rays that crossed Mare Cisrium from
Proclus were brighter in red light than in blue. A similar
effect was also observed, to a lesser extent south of the
Mare. Non-mare Crisium rays from Proclus did not have this effect.
The TLP was not seen at the higher magnification of x100.
The ALPO/BAA weight=2.
Ptolemeus 2020 Jul 27 UT 23:00 N. Travnik (Brazil) observed
visually for 2nd time ever (first seen back in 1970), an
effect on the floor of this crater at local lunar sunrise:
"kind of glimmering mist lifted and wafted inside the shady
hollow of the crater". Almost certainly this is a combination
of atmopsheric seeing on the narrow shadow spires, but we
would like observers to look at this visually or obtain time
sequence images to try to replicate this effect. This report
is assigned an ALPO/BAA weight of 1 for now.
Aristillus 1973 Apr 10 UT 20:18-20:24 Observed by Pasternak (53.33N,

(Meudon, France, 33" x460) whilst checking up on a 1923 28"
refractor sketch by W.H. Stevenson's, thry failed to detect a
prominent floor craterlet (featured in the 1923 sketch) just
inside the W wall. They suspected an obscuration.
Interestingly the whole floor was was reported to be lacking
in detail many hours later as observed by Cragg in the USA.

On 1989 Jun 12 at UT 21:18-22:25 G. North (Herstmonceaux, UK,
Coude, seeing=V) noted at 21:18UT that Torricelli B was
"barely visible"- possibly this was seeing related. M. Cook
(Frimley, UK, 8" reflector, seeing=IV) found Toricelli B to be
ëxtremely dull - impossible to judge shadows on floor in
contrast to Cens." Holmes (Rockdale, England, UK, 8"
reflector, seeing=II-III) at UT21:30 also found Toricelli B
difficult to find at magnifications less than 200x. Cameron
comments that "Dulling is common on it at high Sun but
illumination doesn't seem to be the cause or related". The

45'E, 60mm refractor) "The SW inner wall became brighter at times" -
Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61.
On 2009 Apr 04 at UT 21:40 M.C Cook (Mundesley, UK) after receiving a
telephone alert call, examined Plato crater. Although she did not
report C. Brook's slight mottled pink on the floor of Plato, she did
report through that the floor patches looked darker than normal,
especially in blue light and in red they were not visible at all. In
white light they were darker than normal. A.C. Cook was probably
observing at the same time via a couple of remotely controlled
telescopes in Aberystwyth. The results (time lapse imagery
through narrow band filters) will be examined at a later date.
Note that this observation was made after C. Brook said that he could
no longer see his TLP. Therefore this constitutes a different TLP
as there had been a gap of 1 hour since the last TLP report.
On 1979 Dec 29 at UT 17:45-18:20 Crick (Merchtem, Belgium, 6"
reflector, x140, seeing=III) found a violet spot in the NW inner wall.
The floor was obscured of detail on the northern half. All other
regions studied appeared normal. Observer unsure if this was a TLP or
spurious colour. Cameron 2006 catalog ID=80 and weight=3. ALPO/BAA
