In 1821 May 06 at UT 21:45 Ward (England? Large aperture
telescope, x80), Bailey (England?) and Olbers (Bremen, Germany,
refractor) observed in the Earthlit part of the Moon an apperent small
comet like feature extended from Aristarchus towards Grimaldi. The
light was similar to a glow worm. The observer had never seen anything
like it. The cameron 1978 catalog ID=89 and weight=5. The ALPO/BAA
weight=3.
Cusps 1953 Apr 18 UT 21:00? Observed by Wilkins (Kent, England, 15"?

On 1969 Jul 20 at UT 0845 McIntosh (Auckland, New Zealand, 14"
reflector) saw Aristarchus crater to be brighter in red light. This was
during the Apollo 11 watch. The Cameron 1978 catalog ID=1173 and
weight=3. The ALPO/BAA weight=3.
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
and weight=2. ALPO/BAA weight=2. 6" reflector x64 and x120.
Seeing=III-IV and Transparency=good.
On 1975 Mar 18 at UT17:30 M.Kidger (Winterbourne Down, Bristol, UK,
60mm refractor, x36, very good conditions with a very sharp image and
the sky was almost perfectly clear apart from a very few small clouds).
In Mare Crisium it was observed that only a ray of Proclus could be
seen to cross the floor - normally there are at least four craters
visible inside mare Crisium on good nights and at least one being
visible under bad conditions. So despite it being very clear and the
image quality being good, the observer found it odd that no craters
were visible on the floor of mare Crisium. This is a BAA Lunar Section
report. The ALPO/BAA weight=2.
Observations made by Challis of Cambridge, and N. Pogson of Hartwell,
both of the UK. Before the occultation, Saturn's rings were
distorted. A dark border was seen around the Moon. Just before
re-appearance a sea green colour was noticed. Cameron 2006
catalog extension ID=5 and weight=2-5. ALPO/BAA weight=1.
In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of
twilight (Cameron says also seen by Gruithuisen, Henry and others at
times). Webb gives a low weight to his own observation, saying "for
want of better optical means". The Cameron 1978 catalog ID=130 and
weight=1. The ALPO/BAA weight=1.
On 1988 Jul 21 at UT 01:00? an Unknown observer (name and geographical
position not given in the cameron catalog) detected a darkening on the
floor of Proclus crater - this was also seen by other observers - some
of whom were making observations independently. The Cameron 2006
catalog ID=330 and the weight=1.

On 1970 Apr 13 at UT09:00-09:03 Whelan (Walters, New Zealand, using a
10" reflector) observed Menelaus to have a deep red cloud that seemed
to surge upward from outside the southern edge of the crater wall and
disperse around the outside edge, spreading out on reaching Mare
Serentiatis. All clear again though by 09:03UT, (Apollo 13 watch).

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.
On 1988 Jul 22 at UT 02:15-04:00 P.W. Foley (Kent, UK, 11"
reflector) made a sketch of a dark area of the (East) floor of
Proclus that revealed a large anomalous dark region - there
should be no shade here when the sun is at an altitude of above
50 deg!. BAA lunar section archives reveal similar dark shadings
- however on this night it was a different shaped dark area. The
appearance was confirmed by several observers. Foley reported
that the region affected stretched from Proclus to Theophilus.
The TLP was seen in the USA too by D, Darling as early as
01:31UT and by others on his TLP network - brightness
measurements of the "c.p." were 3.5 and the remainder of the
floor was 5.5. However the observers did not all agree on the
same position for this dark area. The Cameron 2006 catalog ID=
331 and the weight=2. The ALPO/BAA weight=2.

Hernandez (Aguadilla, PR, 8"SCT, x225, S=7, T=4) "Interesting
configuration of shadows with umbra and penumbra. Effect seemed to
reduce over time." An ALPO report. The ALPO/BAA report=2.
2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw
Mons Pico to be incredibly bright. Adee reported naked eye visibility,
though this does not show up in later CCD images. Jarwaski saw another
nearby Mt very bright as well. This has been assigned an ALPO/BAA
weight of 1, though I suspect it is just normal for Pico to get quite
bright at sunrise.
Patches of brightness seen in the area between craters Aratus and Joy.
Seemed to the observer to be perhaps slightly brighter than one would
expect - the observer thought that their observation only barely
constitured a TLP but decided to send the report in anyway. This
has been assigned an ALPO/BAA weight of 1.
On 1983 Sep 15 at UT 05:20-05:24 Louderback (South Bend, WA, USA,
8" reflector and 3" refractor, seeing poor) found that the west wall of
Eimmart was unusually bright (8.3) and apparently it was almost as
bright as the "WEBS(of Aris?) at its brightest". The crater was
apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID=
228 and the weight=3. The ALPO/BAA weight=2.
Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson,
Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw
something in Proclus, alerted Jamieson who saw nothing unusual
at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw
Proc. fluctuate. Red & blue filters showed some reduction in

On 1988 Jul 23 at UT03:07 D. Darling (Sun Praire, WI, USA, 12"
reflector, x150, seeing = 6/10) discovered that the dark area on the
floor of Proclus, seen earlier by UK observers was still present, but
less so (?) and the shape changed. When viewed through a green filter
it was less distinct. "Change with two other filters. Polarizer gave a
circular shape with a knot on SE side & W58 in White." The measured
brightness of Proclus was 9 on three sides and 8.5 on its west rim. The
floor was 5.5, but the dark spot was 4. Alphonsus, Bullialdus,
Copernicus, Eratosthenes, Plato and Ptolemeaus were all normal. The

On 1974 Mar 3 at UT 19:06-20:20 J-H Robinson (Teighmouth, Devon,
UK, 10" refractor, x200, seeing=poor) got a Moon Blink reaction
on the South east wall of Plato, adjacent to the rim shadow and
alerted the BAA TLP network. Ford reported a negtive result at
19:35UT, although Robinson was still getting a blink reaction at
19:40UT, albeit fainter, red at times. Findlay at 19:43-19:52

the previously observed gray area was 1/3 of July 22 and V
shaped and fanned out across the floor. Could see hint of knot
seen before. Craters named in 7/23/88 (#319) were all normal
this time too". Is it possible that this report refers to the
crater "Gray" rather than "Proclus" as the column field suggests
in the Cameron catalog? The Cameron 1978 catalog ID=333 and
weight=5. The ALPO/BAA catalog weight=2.
On 1981 Sep 08 at UT 21:28-21:34 P. Madej (Huddersfield, UK, seeing

Herodotus 2002 Sep 18 UT 22:00 Observed by Raffaello Lena (GLR,
Italy). Event described was of two pseudo-peak/hill-like
features, one on the southern floor of the crater, and another
just slightly to the NW of the centre. on the southern

3" refractor, x150, seeing poor and chromatic aberation on the limb)
detected "purple"in the vicinity of Aristarchus crater and this was
stongest on the north and north west external rims, however there was
no "violet glare"from inside the crater. However the region of the
central peak was very bright - though he could not detect the central
peak. The brightness of the TLP was 4.5 and it should normally be 3
(nimbus area). Near the "big plain"it was 7. The chromatic aberation
seen on the crater. There was also violet on the northen wall of
Herodotus crater and the Cobra Head. Īt appeared dark blue in the blue
filter", the surrounds remained gray". Apparently on the 26th the"ring

(Parnaiba, PI, Brazil, 10" reflector) noticed that on the
dark part of the Moon, Aristarchus was very bright. However
and Cameron (Greenbelt, MD, USA, 12" reflector) at 01:00-
01:15UT on the 17th saw nothing unusual and indeed could not
see Aristarchus. The Cameron 1978 catalog ID=1151 and weight=
1. the ALPO/BAA weight=1.
On 1978 Jan 11 at UT15:30 S.R. Markov, V.V. Davidenko, and A.R. Kharkov
(Ukraine, 10.5" reflector and 1340mm scope) observed a TLP between
Adams and Hase (66.5E, 29S). Photos taken (more than half) show a
bright luminous spot of size 60x70km. The effect lasted 30 seconds. The
Cameron 2005 catalog ID=22 and the weight=5. The ALPO/BAA weight=4
until we have checked checked out the original report.
Aristarchus 1969 Jul 17 UT 2144-2149 Nelson Travnik (Matias
Barbosa, MG, Brazil). "Uncommon brightness of soft blue tone;
gradual decrease till 21:49 when it became normal. Maximum at
21:46. (Apollo 11 watch)". The Cameron 1978 catalog ID=1155.

Snellius to be indistinct (could not locate). Cameron 2006 catalog ID=
23 and weight=1. ALPO/BAA weight=1.
In 1920 Feb 23 at UT 21:00? an Unknown observer saw peaks on the south
cusp were like a string of perls elongating the cusp. Lines drawn
through Stoffler and Curtiunto(?) limb gives position. The Cameron 1978

On 1981 Oct 02 P. Madej (Huddersfield, UK, 77mm refractor,
seeing I to II) noticed that at 20:48 UT Aristarchus had a 2nd
magnitude star-like point on the NE rim (x38). At x83 he could
see a small disc of around 3-6 arc sec in diameter, and at
x111 it looked the ame but bluish-white in colour. He was able
to see Aristarchus, Herodotus, and Vallis Schroteri.
Observations ceased at 21:27 UT due to trees blocking the
view. The ALPO/BAA weight=1.
On 1989 May 10 at UT01:54 D. Weier (Sun Praisre, WI, 12.5" reflector,
x50?) detected a flash east of Grimaldi crater "like a small
electrostatic charge - radiated out like a decorative plasma lamp - not
fuzzy. Darling (Sun Praisre, WI, 12.5" reflector, x50?) saw it but
dismissed it as he had seen it many times before (in same loc?). The
Cameron 2006 catalog ID=363 and the weight=2. The ALPO/BAA weight=2.
On 2002 Aug 12 at UT 19:27 James Cook (Chelmsford, UK) detected a flash
on the Moon. The ALPO/BAA weight=1.
On 1989 May 10 at UT02:30-03:50 M. Wisniewski (Chicago, IL, USA, 8" &
6" reflector, x123) found Aristachus to be unusually bright and
"glowing" as a blue-white magnitude 8 disk, though it faded close to
the end of his observing period (02:30-02:50). A ray from Tycho could
be seen in the direction toards Aristarchus crater. Darling (Sun
Praire, WI, USA, 12.5" reflector, x50) found Aristarchus Z to be both
bright and diffuse. The Cameron 2006 catalog ID=363 and the weight=2.

refractor) saw a TLP in Aristarchus that they had seen
earlier in the evening involving: Luminosity in Aris. strong
& prolonged northward with impression of 2 lum. pts. (Apollo
11 watch). The Cameron 1978 catalog ID 1159 and weight=4. The
