On 1966 Sep 20 at UT 03:22 Three Astronet observers (Phoenix, AZ, and
Los Angeles, CA, USA) (independently?) reported flashes in Grimaldi
crater. One observer was in Phoenix AZ, and another in Losa Angeles,
CA, so probably not due to the atmosphere. Cameron comments that the
astronaut Schmidt on Apollo 17 saw a flash in it while orbiting the
Moon. the Cameron 1978 catalog ID=977 and the weight=5. The ALPO/BAA
weight=4.
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 Jul 19 at UT 19:30-21:30 Gervais (Lodure, France, 4.5"
refractor?) saw the whole region of Aristarchus and its environs
as brighter than normal. Two photographs were obtained. The
Cameron 1978 catalog ID=1156 and weight=5. At UT 20:30-20:55
Oliver (Spain, using a reflector) found the Aristarchus to have
brightened by about 1 magnitude. From UT 20:12-20:30 the crater
had been normal. The Cameron 1978 catalog ID=1167 and the
weight=2. At UT 21:00-00:35 P. Mourilhe Silva (Rio de Janeiro,
Brazil, 19.5" refractor) saw Aristarchus as a very bright
elliptical shape which extended to the north like a bridge
between two points. Jose M. L. da Silva and Ronaldo Mourao (Rio
de Janeiro, Brazil, 13" refractor) saw a brightening on the
north west wall from 21:24-23:22UT intermittently but cont'd.
Wall was extraordinarilly bright, along NW wall brighter.
Moseley (Armagh, Northern Ireland, UK, 10" refractor) detected
an unusual bright, along north west wall, brighter than normal
in Earthshine and brighter than crater. It was not constant, but
pulsated irregularly with frequency of 20 seconds and amplitude
0.75-1.0 magnitudes. No colour seen or obscuration though lokked
for. Clouds interrupted observations. Vasquez (Valparaiso,
Chile, 12" reflector) saw it as a very luminous point of
magnitude 1. Wairy Cardoso (Rio de Janeiro, Brazil, 12"
reflector and 18" refractor) noted a bright. 1s??? The Cameron
catalog ID=1168 and the weight=5. The ALPO/BAA weight=4.
Theophilus 1969 Jul 19 UT 19:30-21:30 Observed by Fox (Notts.
England, 6.5" reflector) and Ringsdore (England, 15"
reflector). Fox saw intermittent glow in Theoph. for > 2h
(time not given). Ringsdore confirmed. (Apollo 11 watch)"
Confirmed by Baum 21:00-21:20UT. NASA catalog weight=5. NASA
catalog ID No. 1166. ALPO/BAA weight=4.
Fracastorius 1973 Mar 09 UT ~19:57 Robinson (Devon, UK) saw a
Moon Blink (colour) in this crater. This crater is long
suspected of giving permanent blinks due to natural colour. The
ALPO/BAA weight=1.
South Pole 2011 Apr 08 UT 19:30-20:00 A.Kemp (Mold, Flintshire, UK) observed that the
Leibnitz peaks at the southern pole stood out sharply. However one of the peaks was “shining
like a spot light. So bright that I couldn’t make out its shape”. – image clear and steady with
excellent transparency and seeing in the 70mm f/13 refractor (25mm and 10mm eyepieces).
Inspections during the above time period revealed no changes in brightness. Previous
observations of this area had never shown such an unusual brightness, and Arthur likened the
brightness to “a maximum brightness of Venus shining amongst 2nd magnitude stars”. The
observer was an experienced observer. ALPO/BAA weight=2.
Mare Crisium 1826 Apr 12 UT 20:00 Observed by Emmett (England?) "Black
moving haze or cloud". NASA catalog weight=2 (low). NASA catalog ID
109. ALPO/BAA weight=1.
Grimaldi 1969 Jul 19 UT 20:39-20:45 Delaye (France, 25cm
refractor) saw a bright bluish spot near Grimaldi. 20:43 a
flash was seen by Thinon. Delaye saw flashes at 20:44 and
20:45. Between 21:00 and 23:00 (J. M. L.) da Silva (Rio de
Janeiro, Brazil, 19.5" refractor) saw a bright spot on the W
(IAU??) of Grimaldi. However there is a bright spot near
Grimaldi, so this maybe normal. NASA ID = 1167. The ALPO/BAA
weight=2.
On 1990 Mar 31 at UT 21:30 L. Jackson (England, UK?) observed a red
glow in Earthshine in Gassendi as shown in a sketch. Apparently
Gassendi can often show up red colours (according to Cameron) but
rarely is this seen in Earthshine. Foley saw the sketch and suspects
that the location was Gassendi. The Cameron 1978 catalog ID=397 and
weight=2. The ALPO/BAA weight=3.
On 1969 Jul 20 at UT 19:55-20:10 Delaye, Thinon, Donas, and Jourdran
(Marseilles, France, 10" refractor, x60) saw between 19:55-20:04UT
Aristarchus to be bright and in it pulsations with 10 sec duration. At
20:05UT it's spot brightened, at 20:08:50-20:35:50UT brightening and
pulsations of variable duration. At 20:55:50UT just a feeble flash.
Cameron comments that this is probably not atmpsheric effects as the
period is too long - also it was during the Apollo 11 watch. The
Cameron 1978 catalog ID=1175 and th weight=3. The ALPO/BAA weight=3.
On 1969 May22 at UT2045-2105 Wald (Zurich, Switzerland) observed the
pinkish colour in Aristarchus was less marked tonight. The astronauts
were alerted and at 22:12 reported no activity but could see the crater
and Earthshine was strong near the terminator. Apollo 10 watch,
spacecraft far from the terminator. The Cameron 1978 catalog ID=1134
and the weight=2. The ALPO/BAA weight=2.
Atlas 1969 May 22 UT 21:20-21:40 Observed by Germann, Wild, Vieli

109. ALPO/BAA weight=1.
On 1969 May 22 at UT23:20 an unknown observer reported some
brightenings with pulsations in Aristarchus crater, Cameron suspects
atmospheric aberrations. This was during the Apollo 10 watch. The
Cameron 1978 catalog ID=1136 and weight=1. The ALPO/BAA weight=1.
2005 Jul 13 UT 01:18 W.Watson (USA, East coast, transparancy:
heavy hazy cirrus, and the only other object visible was
Jupiter) observed a naked eye flash on the Moon in the northern
hemisphere, with a magnitude of -3 to -4. The ALPO/BAA weight=1.
Hyginius Cleft 1966 Jul 25 UT 04:40 observed by Kelsey (Riverside, CA,
USA, 8" reflector, x300) "Points at opposite ends of cleft were very
brilliant in red Wratten 25 filter & very dull in blue Wratten 47

Theophilus 1969 Jul 21 UT 19:30-21:45 and 21:00-22:00 Observed by Fox
(Newark, England, 6.5" reflector,) and Baum (Chester, England, 4.5"
refractor) (S=6, T=4) "At wall, adjacent to Cyrillus was a redish glow,
then obscur. (Fox). Baum saw intermittant white-blue shimmering as if
glowing thru dust glowing & upsurge in brightness on c.p. Gradually
faded to normal at 21:20. 1st time ever seen by him tho. obs. since
1947. Image sharp, no haziness. (indep. confirm. of activity, but
details differ, but same time, Apollo 11 watch)." NASA catalog

On 1991 May 21 at UT05:30-06:15 J. Green (Orangevale, CA, USA, 11"
reflector) photgrapphed a broad bright band stretching east and north
of Cassini crater in 3 exposures taken 10 minutes apart. This
photographic sequence shows a gradual widening towards Cassini and by
the 3rd exposure the band is touching (and then obscuring) Cassini. A
"fan" was visible in the north east and WSW directions, later this was
seen as rays and this was even seen in the view finder of the camera.
Cameron comments that this might be lens flare but suspects that it
would not have been seen in the view finder. The Cameron 2006 catalog
ID=427 and the weight=5. The ALPO/BAA weight=2.
Mons Piton 2022 Aug 04 UT 19:41-20:10 T. Smith (Codnor, UK,
16inch Newtonian, x247, Seeing IV) mountain was very bright
and red around its eastern slopes. An examination of the
bright and contrasty Proclus crater revealed that to be
relatively colour free compared to Piton. An examination of
other features, north and south along the terminator revealed
some tinge of coloiur but not as strong as on Mon Piton. Mons
Piton examined with a yellow filter at 19:50 and still showed
red along the eastern side, other features along the
terminator had no colour through the filter. Video images by.
A.Cook (Newtown, UK) made earlier at 1929 & 19:40 UT, (in the
SWIR (1.5-1.7 microns) did not reveal Mons Pico as especially
bright - but resolutioin was poor. A friend of Smith, phoned
up the next day to say that they saw a mountain on the limb
exhibiting red on the 14th August. Probably the redness was
due to atmospheric spectral dispersion as the Moon was low,
and it was especially visble on Mons Piton as this is an
exceedingly contrasty object on the terminator. ALPO/BAA
weight=1.

Theophilus 1978 Nov 08 UT 20:49-22:00 Observed by J.D. Cook
(Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV)
Orange discolouration seen on ESE crater floor. Moon blink
tried, but no blink detected. By 21:10 the effect had lessened,
but was still orange. By 21:50-21:58 the effect was smaller and
perhaps more on the SE of the floor. Colour confirmed by Foley.
Fitton may also have been observing. At 22:00 A.C. Cook observed
and commented that a darkish, perhaps brown-orange colour seen -
but suspected it was probably spurious colour - but by now the
seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of
several features, including Theophilus, had not noticed anything
unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect
a blink, but noticed intermittent darkining on the shaded area
on the E. floor, but seeing was now IV. The darkening was more
noticeable in blue than red light. BAA Lunar Section

Birt 1955 Apr 15 UT 03:20-05:00 Observed by Capen (California
Seeing=Excellent) "Small craters between Birt & wall were invis. at
times under excellent seeing, while craterlets on w.side were
continually obs." NASA catalog weight=4 (high). NASA catalog ID #586.
Observer made a drawing over a period of 30 minutes. Upon
examining drawing, and comparing with photos made under
similar illumination was struck by the abnormality of a
a small white blob in the north east corner of the shadowed
floor. There should be no raised topography between the wall
and the central peaks that could give rise to this. The making
of the sketch overlapped with an earlier drawing made by Rony
de Laet (Belgium) which did not show this blob. Subsequent attempts
to find sketches/images at very similar illumination angles have
failed to show the blob in the north east corner of the chadowed
floor. ALPO/BAA weight=3.
On 1990 Apr 04 at UT 21:30-21:50 B. LeFranc (France?) reported
observing a white flame effect in Copernicus crater (sketch made) -

On 1938 Mar 13 at UT 04:00-06:00 Barker (Chestnut, England, UK) noted a
slight reddish colour in Plato. However Fox (Newark, UK, 6.5"
reflector, x240) saw none on the south east wall, but instead saw a
yellowish glow on the southern floor at the same time (confirmation?).
Appearently Fox saw the same effect on Apr 10, 11, and May 8-11, then

On 1989 May 17 at UT Fabian (Chicago, IL, USA, 4" reflector, x35-x50
and 8" reflector) noted a pale blue colouration in the ridges situated
west of Aristarchus and north of Herodotus craters, in the vicinity of
the terminator (and on the night side). Aristarchus itself did not have
any colour. Ďt was only area with such color though there were numerous
others of similar elevation and relation to term. The colour was seen
in a 4" Cassegrain telescope, but when an 8" reflector was used at
02:30UT, even with the same eyepieces. Cameron comments that maybe the
larger telescope spread the colour out? The sketch that Fabian
suplied, suggested to Cameron that the TLP was located at Herodotus,
and the ridge was part of Schroter's valley - Cobra Head. The Cameron
2006 catalog ID=364 and the weight=2. The ALPO/BAA weight=2.
Herodotus 1950 Jul 27 UT 03:56 Observed by Bartlett

Aristarchus 1963 Oct 30 UT 01:50-02:15 Observed by Greenacre and
Barr (Flagstaff, AZ, USA, 24" Clark Refractor) observed 2 ruby
red spots - one just to the SW of the cobra's Head and the other
on a highland area east of Vallis Schroteri. A pink colour
formed coverting the SW rim of Aristarchus. Effects present with
or without Yellow Wratten 15 filer. Similar effects checked for
elsewhere on other craters but not seen. So presumed not to have
been due to chromatic aberation or astmospheric dispersion.
Effecta not seen in 12" refractor, but this may have been a
resolution issue. The NASA catalog ID No. is #778. The NASA
catalog weight is 5 (highly reliable). ALPO/BAA weight=4.

Torricelli B 2002 Oct 18 UTC 20:56-21:59 Observer: G.North (UK, 8"
reflector, x134, Seeing Antoniadi IV, Transparency good) - thought that
Torricelli B was perhaps a little brighter than expected, especially
when compared to Moltke and Censorinus based upon past recollection of
relative brightnesses at this colongitude). Slight bluish tint seen as

On 1975 Feb 23 at UT 18:00-00:24 P.W. Foley (Kent, UK, 12 inch
reflector, seeing Good), noticed that Aristarchus was a slate-grey
tinged with blue, and abnormally bright, fading at UT 18:47, and
decreased activity at UT20:45 after a cloudy period. Blue was seen on
the northern wall at UT19:00, but at 19:10 no colour, but instead an
obscuration. All normal from UT 21:04-21:46 according to Foley. At
UT19:00 G. Amery (Reading, UK, 10 inch reflector) noted shadowy grey

On 1983 Aug 22 at UT 05:44-06:33 D. Louderback (South Bend, WA, USA,
3"refractor, x150) found the brightness of Aristarchus (diffuse white
patch) to be 7 to 7.5 but apparently it is normally 8-8.5, so fainter
than normal. Another brightness reading found "brightening then nearly
extinction at S. wall similar to changes seen on Eimmart before.
Watched fluctuation compared to Cobra Head, they were similar but more
pronounced at Aristarchus" especially in blue light compared to red
(although there was a little brightness in red). Timings of these
fluctuations were 7sec, 7sec, 9-10sec and 9-10sec. The latter two might
have been seeing related as the crater enlarged up at these times. The
observer felt that the Cobra Head appeared fainter than the previous
year and had faded during the second set of brightness measurements.

mission then the date is wrong - possibly the year should have been
1994? The Cameron catalogue does actually mention a TIFF on Clementine

James Short, Dr Harris and Mr Stephens saw initially a streak of
light on the shadowed floor of Plato. They were not expecting to see
any light to reach the floor. Shortly afterwards they saw a second
streak of light parallel to the first and this shortly divided

but they were unable to understand why one of the streaks divided
into two. Cameron's 1978 assigns this TLP an ID of 20 and a weight
of 5. The ALPO/BAA catalog assigns a weight of 1.

the weight=1. The ALPO/BAA weight=1.
On 1980 Oct 12 at UT23:30 D.Darling (Sun Praire, WI, USA, 12.5"
reflector, x75, seeing 10/10) observed the crater to be glowing faintly
- photos showed it to be blue. Cameron 2006 TLP catalog ID=113 and
weight=3. ALPO/BAA weight=1.
Mare Crisium 1998 Jan 31 UT 17:15-17:35 R. Braga (Corsica
(MI), Italy, 102mm f8.8 refractor, x180, with no diagonal,
seeing II, Transparency poor). A very bright point located at
23N 54.5E this was normal! - what was unusual was that it
vanished when viewed through a blue Wratten 38A filter (this
filter absorbs red, UV, and some green light). The ALPO/BAA
weight=2.
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"?
reflector) "Faint extension of the cusps. (high peaks in sunlight)."
NASA catalog weight=2 (low). NASA catalog ID 558.
Cusps 1953 Apr 18 UT 21:00? Observed by Wilkins (Kent, England, 15"?
reflector) "Faint extension of the cusps. (high peaks in sunlight)."
NASA catalog weight=2 (low). NASA catalog ID #558.
Messier 1981 Sep 03 UT 19:15-19:55 Observed by Evans (England, 254mm
Newtonian, seeing II-III, transparency fair). "Messier was under going
obscuration" BAA Lunar Section Circular report. ALPO/BAA weight=1.
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.
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 1990 Mar 02 at UT 19:35-19:50 P. Williamson (Shropshire, UK, 14"
reflector, x178, seeing=good and steady) noticed a yellow-orange glow
in Gassendi (from a small illumnated crater?) in Earthshine at 19:35UT
and by 19:40UT it had become very bright white, afterwhich it
completely faded within 10 minutes. The Cameron 2006 catalog ID=393 and
the weight=1. 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.
