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 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.
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.
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 2012 Mar 28 at UT 20:45-20:50 Two unknown Italian
observers, reported on an on-line formum that they had
independently seen a distinct glow with a comma/drop shape.
One of them moved the Moon and the glow moved with the Moon.
It is uncertain how experienced the observers where. A chart
was provided which shows the lcoation of the glow in the
western side of Mare Imbrium. It is just possible that this
was Aristarchus in Earthshine, though that is very slightly
further west and south than the observers reported. ALPO/BAA
weight=1.
On 1969 Jul 20 at UT09:30 Whelan (Wellington, New Zealand, 10"
and 6" reflectors. Other observers involved were: Mackrell
(New Zealand, 6" reflector) and Spellman (4" reflector)
observed Maskelyne crater undergoing a whitish glowing
brightening. Shadowy filling of whole crater. Apollo 11 watch.

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).
Drawing supplied. Cameron 978 catalog ID=1246 and weight=3. ALPO/BAA

Jansen 1966 Aug 24 UT 04:15-04:25 Observed by deBerard (Flossmoor, IL,
USA, 6" reflector, x360, S=V, moonblink used) "Bright green glow --
using red & blue filters & green polariz. filter." NASA catalog weight=
3 (average). NASA catalog ID #965.
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.
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.

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
brightness. E. edge showed darkening, but not as dark as in
shadows. 10 min later, returned to normal. (Sparks confirmed
Dean)." NASA catalog weight=5. NASA catalog ID #1267. ALPO/BAA

On 1990 May 03 at UT 02:03 D. Darling (Sun Praire, WI, USA, seeing
steady) observed a point of light inside Alphonsus just to the north
of the central peak, along the "center ridge". It was seen again, half
way between the central peak and the noth west rim - along the ridge.
All other features were normal. The Cameron 2006 catalog ID=403 and the

Purbach 1970 Apr 14 UT 12:00-14:00 Observed by Osawa (Awajt-Shima,
Japan, 8" reflector, x288) "Photos in blue and orange taken. Ill-
defined obscur. in blue photo in S. part of crater compared with

Alter's findings in Alphonsus)." NASA catalog weight=2 (low). NASA
catalog ID #1250.
On 1972 Apr 21 at UT19:01 Mattingly (Apollo 16 commander, in orbit
around the Moon, using his naked eyes) saw a bright flash from below
his horizon on the lunar farside (approximate longitude=180 deg). he
was dark adapted at the time. However no sesimic event was recorded and
so Cameron suspects that this was not a meteor impact but a cosmic ray
striking his eye. The Cameron 1978 catalog ID=1331 and weight=3. The
ALPO/BAA weight=3.
Alphonsus 1967 Aug 13 UT 18:40-18:55 Observed by Horowitz (Haifa,

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,

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
and 20:00-20:05 saw nothing unusual. Robinson at 19:56UT no
longer saw a blink, but it returned at 20:05UT. Light in bothred

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
floor of the crater. Lena suspects a combination of seeing
effects and albedo markings on the floor. However this effect of
two spots on the floor has not been repeated again.For further

Herodotus 1998 Dec 30 UT 18:50-19:10 observed by J.Knott
(Liverpool, UK 22cm Newtonian, x216, seeing II, transparency
good). Observer reports a bright spot, as bright as the
central peak in Aristarchus on the NW rim of Herodotus at
19:10 (still there at 19:15, but the curious thing was that it
was not visible earlier at 18:50? Now there is a bright
craterlet here, and the observer doubted if what he had seen
was unusual - though we have the rise in brightness o20
minutes to account for? The ALPO/BAA weight=1.
On 1975 Mar 25 at UT18:50-20:50 P.W. Foley (Kent, UK) observed
blue/grey in Aristarchus. The ALPO/BAA weight=1.
On 1983 Sep 20 at UT 05:08-06:13 Louderback (South Bend, WA, USA,
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
was still dark with faint violet - nearly normal". Cameron comments
that the TLP was due to spurious colour. The Cameron 2006 catalog ID=

to the east of Briggs and an E-W trending lineament or wrinkle
ridge that did not show on NASA LAC charts. Further checks did
not reveal it on Lunar Orbiter mosaics, but the craterlets
(and not the E-W trending ridge) were visible in LROC
topography data. The ridge is possibly a very low relief
feature that shows only under very shallow illumination
conditions. The ALPO/BAA weight=1 until we get confirmation at
repeat illumination.

Moon Blink carried out. In Red 25 Proclus looked nearly the
same as in white light. Through the Blue 38a filter, however, only the
brilliant lit south east wall was clearly visible. The northeast wall
was very dim with this filter. With no filters the NE and SE wall were
brilliantly lit, the SE wall was almost as bright as Aristarchus. A
thread like strip along the NW wall, possibly the rim of the crater,
was also brilliantly illuminated. The interior of the crater was a
featureless stygian black with the exception of a brilliant (intensity

entirely. The observer felt that the cause may have been
psysiological - or short-lived spurious colour. However
interestingly nearby craters did not show the effect. A

maybe a misprint, should be 11/1/63? - sunset terminator at 25W and
Copernicus in dark. The Cameron 1978 catalog ID=782 and weight=0. The
ALPO/BAA weight=1.
On 1963 Nov 10/11 at UT 23:35-00:32 Kopal (Pic du Midi, France, 24"
refractor) observed a TLP in Kepler. Cameron says that the date maybe a
misprint, should be 11/1/63? - sunset terminator at 25W and Copernicus
in dark. The Cameron 1978 catalog ID=782 and weight=0. The ALPO/BAA
weight=1.
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 Nov 11 at UT 17:00-17:30 E.V. Arsyukhin (Moscow, Russia, 3"
reflector) saw three stationary dark spots suddenly appear in Mare
Crisium. There was one on the north and the other two in the south west
to south. They lasted approximately 30 minutes and then promptly
vanished. Cameron says that it cannot be this date because the Moon was
not visible at 17:00UT Suggests 05:00-05:30UT? The Cameron 2006 catalog
ID ID=189 and weight=3. The ALPO/BAA weight=2.
On 1978 Jan 06 at UT 01:00 Anorati (Firenze, Italy) observed inside a
"good sized crater?" an orange light that became bright green. The
efect did not recur over the many hours of observing. The observer did
not suspect that it was a meteor, but instead produced by an
intelligent being????? Cameron suggests a terrestrial meteor?
