Bright point seen near Plato. A much brighter one was near
Aristarchus. Apparently seen by both Schroter and Bode.
The Cameron 1978 catalog ID=43 and weight=5. The
ALPO/BAA catalog weight=3.
Bright point 26" N of Aristarchus rim. Resembled one
near Plato but less conspicuous. The was a confirmed
observation by Schroter and Bode?
On 1965 Aug 03 at UT 04:18-04:24 Bornhurst (Monterey Park, CA, USA,
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
ALPO/BAA weight=4.
On 1965 Oct 01 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=897 and weight=1. The ALPO/BAA weigh=1.
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.
M. Price of Camberley, UK noticed that an area in relation
to the central area of the floor could not be resolved. Averted
vision was used, but this did not help to resolve detail. The crater
was close to the terminator and was in general sharply in focus
apart from the suspect area. No spurious colour seen. Sketch
supplied.P. Foley wonders if the effect was due to the resolution
limit of Price's scope? Cameron 2006 extension catalog ID=78

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 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

In 1962 Sep 16 at UT08:05 Wildey, Pohn (Mt Wilson, CA, USA, 60"
reflector) Taruntius faded from Vmag-3.21 to 4.04, a 0.82 difference in
magnitude in 2.5 hours - a photometric measurement. The average
magnitude for this age is 4.03, so therefore the crater had brightened

On 1989 Jun 20 UT 0628-06:58 R. Manske (Sun Praire, WI, USA, 1"
refractor) discovered blue on the north west inner wall and red on the
south east outer wall. At 05:39 he could see the blue but not the red.
No colour was detected on Tycho, but he thought that he could detect a
pinkish colouration over the whole Moon. The Cameron 2006 catalog ID=
367 and the weight=1. The ALPO/BAA weight=1.
Plato 1966 Sep 02 UT 0625 Observed by Kelsey (Riverside, California,
USA, 8" reflector x300) "Landslip at west would not focus. (Ricker not
certain it was a real LTP)." NASA catalog weight=2 (low). NASA catalog
ID 973.
In 1950 Jul 02 UT07:22 Bartlett (Baltimore, MD, USA, 3.5"
reflector) saw no dark bands on the inside of Aristarchus,
despite detail being seen elsewhere. He would normally have
expected to have seen bands at this colongitude, based upon past
observations. The ALPO/BAA weight=2.
Aristarchus 1983 Oct 23 UT 19:00-01:30 Observer: Foley (Kent, UK,
12" reflector, seeing=II) noiced at 19:00UT an extended bright
spot on E wall and extending beyond. This was brighter than other
areas of the crater. There was also occasional star-like
glistening. Foley comments that the inside of Aristarchus was
slightly obscured. The TLP started fading from UT20:30 and
finished by 01:30UT. six out of nine independent observers
confirmed the effects seen. In total 14 observers observed, 9
reported back and 6 found abnormalities in Aristarcus though all
encountered variable seeing conditions - some had spurious
colour. Cameron comments that this was one of the best
recorded/confirmed TLP events. All CED brightness measurements
obtained were very high. Moore, Nicolson and Clarke (5" refractor
and 15" reflector, 230-350xseeing III) found the crater to be
very bright at 19:11UT through a 5" refractor and there was a
blob on the east rim (Bartlet's EWBS?) at 19:14UT. Nicolson also
saw a very bright star-like area on the eastern wall but this was
not defined as it usually is. The crater was also very bright at
22:43UT using the 15" reflector available to these observers. At
01:07UT they used a Moon blink and discovered that the bright
region was bright in blue light and less bright in red - although
this was not a detactable blink when switching rapidly between
filters. They found that the crater had returned to normal by
01:15UT. M.C. Cook (Frimley, UK, seeing III-IV) observed a large
diffuse spot on the east of the crater that was brighter in blue
than in red light and the CED device gave a high reading. J.D.
Cook (Frimley, UK, seeing III-IV) made a skecth that showed the
bright spot extended on the east wall - again the CED reading was
high and a lot of detail was visible on the floor. A.C. Cook
(Frimley, UK, seeing III-IV) also noted remarkable detail and the
bright (as confirmed by CED) blob on the eastern rim. G. North
(Sussex, UK, seeing III-II) also confirmed the bright blob on the
eastern wall. Wooller found the north west wall was a dirty
yellow colour - though no colour was seen elsewhere in or outside
the crater. Mosely found the crater to be bright and his sketch
revealed the extension of the bright blob on the eastern rim and
again a great deal of interior detail. Amery (Reading, UK, seeing
III) found Aristarchus to be "a brilliant splash against dulled
background in violet filter, especially polarizing filter. CED +
polarizer readings high, but not as high as previous night".
Mobberley (Suffolk, UK, seeing III-IV) remarked that "spurious
colour a total mess around Aristarchus & nothing abnormal seen".
A photograph was taken at 20:50UT reveals the bright blob and
entire detail. Peters (Kent, UK, seeingIII-II) observed
Aristarchus with a UV screen from 20:15-21:23UT and comented that
althogh being very bright, there was no variation between white
and UV. It was checked with a Moon Blink device and the radial
bands were clearly seen in white light, < in blue. The Cameron
2008 catalog ID=233 and the weight=5. The ALPO/BAA weight=4.
On 2002 Sep 23 at UT22:45-23:56 C. Brook (Plymouth, UK) noticed that
the bands inside Aristarchus varied (UT22:45-22:56) in definition
whilst the rim of Herodotus and the rays of Kepler and Copernicus
remained sharp. These bouts of variation were 1-2min in duration. At
23:56UT when he checked again the periodic blurrings of the bands were
still present. The observer suspected atmospheric effects. M.Cook
(Frimley, UK) observed 22:00-22:30 and could see only 2 bands on the
west wall - but this may have been because of poor transparancy. The
ALPO/BAA weight=1.
Aristarchus 1964 Oct 23 UTC 02:35-02:45 Observed by Bartlett
(Baltimore, MD, USA, 3" refractor, 133 & 200x, S=3-5, T=4) "South floor
region granulated, 6 deg bright with very faint trace of pale yellow
color; rest of crater 8 deg bright." NASA catalog weight=4 (good), NASA

On 1989 Jun 21 at UT07:03-07:27, R. Manske (Sun Praire, WI, USA, 1
"refractor) found the colours pink and blue on Aristarchus, like the
previous day, however this time there was also an orange tinge on the
"back"" (North?) rim of Sinus Iridum and the same too on mare Crisium,
all the way past Plato, in the direction of Cassini. This colour was
not seen at higher magnifications. The Cameron 2006 catalog ID=368 and

Solar Selenographic colongitude=241.3. Observer saw an extremely
attenuated cusp extending well beyonf the Moon's prime meridian.
There were also dusky ill-defined stips along the Earthlit limb
nearby. 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.
On 1847 Dec 11 at 18:00UT Hdgson (Eversley, UK, x80 refractor and 40x
reflector) observed in Plato (Though it might have been Cape Agassiz or
Teneriffe Mts) a bright spot of about a 1/4 the angular diameter of
Saturn that varied intermittently and was at all times visible on the
night side of the Moon. The following day he glimpsed the same spot
rhough clouds. From his drawing the spot was ~5' below the true N.
point & near the following limb (IAU E. limb) Cameron comments that
Plato fits the angular distance better than the other two candidates
unless there was a large northern libration. The Cameron 1978 catalog

On 1988 Apr 21 at UT 01:28-04:00 D. Fryback (Madison, WI, USA) took a
series of photographs - Aristarchus was a luminous patch and in one
photograph a red spot (Cameron suspects marks on the film). is seen
near Aristarchus. Strangely though when looking through the telescope,
the crater was not excessively bright. D. Spain (Fairdale, KY, USA,
3.5" reflector?, x60) observed a narrow white streak of mag 5-6 of
duration 0.5 sec that covered 160-320km near the centre of the Moon at
01:53UT. A similar streak happened but the direction was different.
Next 2 small red flashes were seen at 02:00 and 02:01UT of magnitude 7

On 1969 Jul 19 at UT 1845-18:47 Pruss and Witte (Bochum, Germany, 6"
refractor x36 and binoculars) saw brightenings in the north west wall
of Aristarchus for 3-7 seconds of about 1 magnitude over the
background. From orbit at UT 18:46 the Apollo 11 crew Armstrong,
Aldrin, and Collins (in orbit around the Moon and using the naked eye)
were asked to take a look at Aristarchus after Earth-based reports of
TLP activity. Armstrong reported (after the solar corona had set, on
the night side) that probably Aristarchus "to be considerably more
illuminated than the surrounding area. It just has - seem to have, a
slight amount of flourescence to it". Collins reported a moment later:
"Looking out on the same area now. Well at least there is one wall of
the crater that seems to be more illuminated than the others. I am not
sure that I am actually identifying any phosporesecence, but that
definitely is lighter than anything else in the neighborhood". Houston
then asked if the crew could detect any colour and if the inner wall
was the inner or outer part? Aldrim commnted that it was the inner
wall and Collins mentioned thatno colour was incolved. The Cameron 1978
catalog ID=1165 and weight=5. The ALPO/BAA weight=3.
On 1969 May 21 at UT 20:00-21:00 Brandli and Germann (Switzerland, 6"
