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.
On 1966 Sep 09 at UT 21:00-21:30 Cave (England, UK, 6" reflector, x364,

shades darker (on scale of 1-10) than the floor of Nasmyth and nothing
to be seen on it even along the ridge. A drawing was made. The Cameron
1978 catalog ID=976 and weight=3. The ALPO/BAA weight=2.

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).

On 1965 Aug 01 at UT 05:00 Welch (Table Mountain, CA, USA, 6"
reflector, seeing=excellent) observed some star-like flashes in
Aristarchus in ashen light. Cameron says 7/31/65 in MBMW=local time =
6/1/65 in UT. The Cameron 1978 catalog ID=886 and the
weight=2. The ALPO/BAA weight=2.
On 1969 Jul 18 at UT06:15-08:00 Heath (Christchurch, New Zealand) noted
that Aristarchus was brighter than normal (Apollo 11 watch). The
Cameron 1978 catalog ID=1157 and weight=1. The ALPO/BAA weight=1.
On 1973 Apr 06 at UT19:34-19:40 E. and C. Moore (England?, UK)
and Hitchens (Lincolnshire, UK, 11" reflector) observed the
following in Aristarchus crater: "Unusual brightness . Att'n
drawn from occultation. Had a bright pt. of mag. 7 as if
slightly defocussed star, yellowish in color on NE (IAU?) rim.
Brightened & expamded. Later scintillate. Wife called, each
idep. drew same phenom. Hitchens also saw glowing in same time
period (indep. confirm.)". The Cameron 1978 catalog ID=1365 and

On 1970 apr 11 atUT 05:29 Lucas (San Diego, CA, USA, 10" refelctor,
seeing=fair) and others (Oregon, USA) obtained a photometric record of
light level changes in Grimaldi crater. Visible reports by others
during the same time. The photometer paper chart pen moved off scale on
a 10mV scale adjusted to 1000mV. The peaks correlate with the visible
observers from California and Oregon. Bright flashes, 3-5 events
(confirmation during the Apollo 13 watch). The Cameron 1978 catalog ID=
1237 and weight=5. The ALPO/BAA weight=4.
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.
ALPO/BAA weight=1.
In 1937 Feb 15 at UT 16:00? Arkhipov (Russia) observed in Cassini:
"Blue-greenish scintillating spots at bottom of crater were vis. on

10" reflector, x240, S=F-G) and Leasure and Emanuel (Whittier, CA, USA)
observed some star-like flashes in Aristarchus in ashen light
(confirmed). The Cameron 1978 catalog ID=888 and the weight=5. The

On 1969 Jul 20 at UT 0530-0540 Younger and Byl (Victoria, BC, Canada,
48" reflector) saw a fuzzy brightening near Aristarchus of less than
0.5 minute of arc diameter (Apollo 11 watch). The Cameron 1978 catalog
ID=1171 and weight=4. The ALPO/BAA weight=2.
Proclus NW ray 2003 Sep 02 UTC 02:20-03:35 Observed by Haas (Las
Cruces, NM, USA) "Everyone knows the bright ray running northwest from
Proclus. In this view from 2:20 to 2:36, UT on September 2 I remarked a
thin, pink southwest border to the ray. One thinks of chromatic
aberration, and the position supports this interpretation; but other
bright lunar features showed no such effect. The pink border lay 1 to
2.5 diameters away from Proclus (S=2, T=3.5). At 2:55, UT (S=1-2, S=
3.5) the border was gone; neither its appearance nor disappearance was
observed. At 03:25 UT there is no sign of the pink border (S=2, T=3),
moreover the Moon was lower, so atmospheric dispersion must be greater
by now? 12.5" Newtonian x321 at 02:20-02:36, x202 at other times.?"
Note that experiments to simulate spurious colour using Adobe Photoshop
were able to recreate colour in the correct place on the NW ray -
however there should have been colour reported on the SW ray too and
there was no mention of this, therefore the observational report is
intriguing. The ALPO/BAA weight=2.
On 1967 Jul 20 at UT 07:00 Whelan, (Wellington, New Zealnd) saw a
pulsating glow from Aristarchus crater, and this continued, although
less pronounced. This was during the apolo 11 watch. The Cameron 1978
catalog ID=1172 and the weight=2. The ALPO/BAA weight=2.
On 1974 Feb Weith-Knudson (Copenhagen, Denmark, 12" refrlector, x72)
observed a magnitude 7.7 flash (comparison between SAO093043=mag 7,8
and SAO093052 mag=7.5 that happened to lie in the field of view at the
time) in Earthshine. The observer speculates whether this was a lunar
meteorite impact or a reflection from an artificial satellite (or
indeed as Cameron suggests from an Earth meteor?). The cameron 1978
catalog ID=1388 and weight=0. The ALPO/BAA weight=1.
On 1965 Oct 02 at 04:00UT an unknown observer saw a TLP (feature name
not given in the Cameron catalog - nor a description or reference). The
Cameron 1978 catalog ID=898 and weight=1. The ALPO/BAA weigh=1.
Theophilus 1972 May 19 UT 23:48 Theophilus observed by Ruchatz (51N
10E, 60mm refractor, T=4, S=2) "Diminution of brightness of the S wall

30cm reflector, seeing IV, transparency moderate, very litle
spectral dispersion noticed - Wratter 25 and 44a filters used)
UT 21:16-21:19 Censorinus slightly brighter in red and more
detail seen. Observed other features before and after this.
Checked again UT21:31-21:40 - same appearance. Torricelli and
Torricelli B in comparison looked normal with other craters of
similar size. ALPO/BAA weight=1.
Proclus NW ray 2003 Sep 03 UTC 02:46-03:07 Observed by Haas (Las
Cruces, NM, USA) "The curious reddish edge to the conspicuous bright
ray running N2 from Proclus is seen again (x321, x366 (S=1-3, T=3.5-
2.5). It lies on the SW side of the ray, with no corresponding blue
border on its NE edge. The effect persists as the Moon drifts across
the whole eyepiece field. However at 03:46 (x202) the coloured edge is
not recognized now, but perhaps only because of worse conditions (S=3,
T=2) 12.5" Newtonian reflector used." The ALPO/BAA weight=3.
On 2010 Apr 20 some time between UT 22:00 and 23:00 I.

Near archimedes 2001 Sep 25 UT 08:30 Observed by Try (Whangarei, New
Zealand, 4" f/10 reflector) "observed two possible L.T.Ps. on the edge
of the terminator near the crater Archimedes. They appeared to be two
bright points of light about the size of Mount Piton. They seem to
form a triangle with Mount Piton. He observed them for two hours and
they were still visible when he ended his observing session. He was
observing with a 4" f10 reflector. Then Moon age was 7.9 days old and
the colongitude was 4.83. submitted a drawing showing the area where
the lights were observed." ALPO report. ALPO/BAA weight=1.

D.Harris and E.Arriola (Whittier, CA, USA, 19" reflector x146,
and spectrum, S=4, T=1-0) "Absorp. spectrum (visual) of c.p.
band at 475+/-5nm (1st est.); 2nd est. at 485+/-5nm. Band
degraded towards the viol. Band nr.Hydrogen Beta. as if
abnormally broadened. So sign of anything unusual visually in
central peak in white light. Absorption appeared only on C.P.,

NASA catalog weight=5. NASA catalog ID #948. ALPO/BAA weight=5.
Large plume-like diffuse cloud over central peak, very
large compared to central peak (@ approx 30km diameter)

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
