On 1969 May 20 at UT 21:00-22:00 Bury (France, 4" refractor) observed
Aristarchus to be very bright, as an elliptical bluish spot at 21:00UT.
This observation was made during the Apollo 10 watch. The Cameron 1978

On 1969 May 20 at UT 21:10-22:30 Marcomede Rangel Nunes and
Julio Dias Nogueira (Rio de Janeiro, Brazil, 18" refractor)
Harpalus brighter than Bouguer - this was during the Apollo 10
watch and Cameron comments that the observers were
inexperienced. The Cameron 1978 catalog ID=1129 and weight=0.
The ALPO/BAA weight=1.
On 1988 Apr 21 at UT 01:53 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 again but the direction was different. Next 2
small red flashes were seen at 02:00 and 02:01UT of magnitude 7 (<1sec)
in the vicinity of Aristarchus. The Cameron 2006 catalog ID=327 and the
weight=1.
On 2002 Aug 12 at UT 19:27 James Cook (Chelmsford, UK) detected a flash
on the Moon. The ALPO/BAA weight=1.
On 2011 Apr 07 UT 19:45-20:10 Aristarchus was seen to be “very
bright” in Earthshine. Giorgio Sancristoforo (Milan, Italy,
203mm SCT, atmospheric seeing good) noticed Aristarchus to be
exceptionally bright (Sketch supplied) at around 20:00 and was
the first to report this. Although he did not record the start
and end times, he commented that the effect lasted 20-30 minutes
and then was significantly reduced in brightness. Although
direct comparison in terms of brightnes could not be made with a
star, he thought Aristarchus to be brighter than +0.7 in
magnitude (Saturn). Furthermore Aristarchus was visible when
daylight was still present, when looking through the telescope,
although it could not be seen with the naked eye due to too much
extraneous light. Aristarchus was probably white in colour, but
the observer was partly colour blind and so was uncertain. Not
much detail was seen elsewhere in Earthshine, even when the sky
darkened, and he was not able to see Kepler or Copernicus, just
the limb. No details were seen in Aristarchus itself, for
example no ray to the SW was visible. It later transpired that
Lajos Bartha (Budapest, Hungary, 70mm refractor, x83, seeing
conditions good) had observed Earthshine even earlier from
UT19:45-20:10 and noticed a bright area close to the edge of the
Moon that he later confirmed was Aristarchus. When he started
observing the sky twilight was still a deep blue, but the dark
side of the Moon was seen both with the naked eye and through
the telescope. Earthshine was medium in brightness and grey in
colour. Copernicus and Kepler were weak in brightness but
certainly visible. There was some scattered light from the
sunlit side of the Moon noticed, but not enough to obscure
Copernicus and Kepler from visibility. As a test he moved the
telescope around and the bright spot moved with the Moon and so
was not a glare problem. The following day he checked Earthshine
again but found that the bright spot was not so conspicuous. As
a footnote, Tim Haynes (UK) had been observing an occultation of
37 Tauri, much earlier at 19:14UT, through 10x50 binoculars. He
commented that Earthshine was visible, but that he hadn't
noticed Aristarchus - though he was not looking at the Moon
specifically to see this crater. ALPO/BAA weight=3.
Mare Crisium 1826 Apr 12 UT 20:00 Observed by Emmett (England?) "Black

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 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.
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.
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.
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.
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.
Mare Crisium 1826 Apr 13 UT 20:00 Observed by Emmett (England?) "Black

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.

(confirmed by CED readings). Cameron 2006 catalog ID=247 and weight=3.
ALPO/BAA weight=1.
On 1984 Jul 05 at UT 00:00-01:25 Marshall (Medelin, Columbia) found
Proclus to be much brighter than Censorinus (which of the two was
abnormal is a question) - though he thought that Censorinus looked
dull. The Cameron 2006 catalog ID=247 and weight=3. The ALPO/BAA

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.

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

weight=1.
On 1972 Feb 23 at UT0010-0035 Fornarucci (Garfield, NJ, USA, 6"
reflector, x250, seeing=fair and transparency=3.5). Shading
usually visible west of it was not seen. Cameon comments that
the albedo must have been at 5, where normally it is 4.5 and the
nearby plain is 5). Cameron 1978 catalog ID=1322 and weight=2.
ALPO/BAA weight=2.
Plato 1964 Nov 14 UT 01:00? Observed by Bartlett (Baltimore,

On 1980 Jan 26 at UT21:35-22:25 Blair (Refrewshire, Scotland, 10"
reflector, 83-276x, seeing=III-IV and transparency poor) discovered a
bright spot on the north rim and through filters it "flashed" green,
red and blue. Clouds interupted observing, but when they cleared the
effect was still present. Other craters did not show this effect.
Cameron catalog ID=83 and weight=4.
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.
Birt 1955 Apr 15 UT 03:20-05:00 Observed by Capen (California
Seeing=Excellent) "Small craters between Birt & wall were invis. at

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.
Aristarchus 1963 Oct 30 UT 05:00-08:00 Observed by Greenacre and
Barr (Flagstaff, AZ, USA, 24" Clark Refractor) a violet or
purple-blue colour formed beyond the NW of Aristarchus. ALPO/BAA
weight=2. This followed an earlier observation that night of two
red spots and a pink glow.
Aristarchus and Cobra Head 1966 Jul 30 UT 06:35-07:29 Observers Ariola
and Cross (Whittier, CA, USA). NASA catalog states: "S. part of Cobra
Head nr. Herodotus was a red spot; also nr. Aris. & the fork of
Schroter's Valley. Variations in phenom. color, 1st on S. rim of Aris.,
later on N. rim. Drawings". 19" x390 reflector used. NASA catalog

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
well. The ALPO/BAA weight=1.
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
near the shadow under the south wall, indistinct small area, no colour.
At UT 20:00 activity increased. Colour negative fr. 150-300x till 21:10
(Hunt, Cambridge, UK, 2.5" refractor, seeing Poor-Very good). Negative
fr. 20:20-21:00 in bad seeing, and very good seeing at 200x all
negative (colour blink filters). From 23:45-00:20UT (Fitton,
Lancashire, UK, 8" reflector). Turner of Sussex, UK with an 8"
reflector, observed as well. (confirm. of activity earlier & neg.
later). Cameron 1978 catalog ID=1397 and weight=5. ALPO/BAA weight=3.
On 1975 Apr 23 at UT 20:30 J-H Robinson (Teighmouth, Devon, UK, 260mm
reflector, x200). Observer was observing since 20:30UT, at 21:00UT
though they noticed red on the outside south wall of Aristarchus, a
hazy ill defined area that was larger in a red filter than in blue
filter, and outside east wall was bright in red. At 21:08UT the outside
west wall of Aristarchus no longer gave a colour blink reaction, and at
21:22UT the colour blink on the southern end of the crater ceased, but
the image blur remained (in both red and blue filters) despite the rest
of the crater being sharp in detail. Observations ceased at UT 21:35
because the blurring at the southern end seemed to be normal and this
was confirmed when checked with photographic atlases. Other craters
such as Proclus, Pickering, Tycho, Gassendi, Copernicus, Alphonsus,
Plato, Menelaus, Manilius, Linne and Theophilus, showed no colour blink
reactions. However Picard had a red bright blink from 20:30-20:40 and
the permanant blink on the N. Floor of Fracastorius was detectable.
Also Plato floor shadings were clearer in red than in blue -
intermittently. This is a BAA lunar section observation. No estimation
of transparency or seeing is given, nor any comment on whether spurious
colour was seen in any craters visually. ALPO/BAA weight=1.
On 1981 Oct 11 at UT 00:05-02:00 B.Hobdell (St Petersberg, FL, USA, 4"
refractor, S=3 and T=5) observed a brightening on the floor of Plato. 4
bright spots appeared and vanished and there was a fith one in the
centre that was very bright at times. At UT 00:14 the central spot
became bright then was "followed by a haze permeating entire floor,
heaviest in the northern quadrant. Came from 2 S peaks or white spots,
shaped like a boomerang extending to presumed c.p. (c.c ?). White
flashed at 0052 from it cloud changed shape - spread N. At 0136
brightening from c.c. area 0419 dissipated. All white spots seen at
0200. Its outer flanks seen clearly the whole time". The above is
quoted from the Cameron 2006 catalog ID=155 and weight=3. The ALPO/BAA
weight=3.
On 1981 Nov 10 at UT 07:54-08:22 D. Louderback (South Bend, WA, USA,
3" refractor and filters, seeing=2-3 and transparency=5) observed a
blue light at the Cobra's Head, near Aristarchus, that fell back down
to a normal brightness of 7. although the west wall (his point D) went
down to 6.5 (this was 8 back on Oct 5). The Cameron 2006 catalog ID=158
and the weight=3. The ALPO/BAA weight=2.
Interior bands were faint at 22:40 but sharper at 23:20.
Observer noted some blue spurious colour to the north of
Aristarchus but this had gone by 23:50.
Observer noted some variability in the brightness of Moltke
and Torricelli B. This observation has an ALPO/BAA weight of 3.
Observer noted some variability in the brightness of
Torricelli B and Moltke. This observation has an

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.

Galvani B: On 2019 Sep 13 UT 23:26 K. Kilburn (Manchester, UK,
BAA - ED80 refractor, x2 Barlow, Canon 550 DSLR) took a
sequence of images from 23:25-23:27 UT. On one of the images,
taken at 23:26UT there is a blue/green spot on Galvani B.
There is a hint of a possible fade of the spot in the other
images but this is not conclussive. Te spot might just be a
cosmic ray event or a bright part of the crater rim coming
into view under brief exceptional seeing for one frame only.
We need simlar illumination, and if possible topocentric
libtation images, under different atmospheric conditions to
confirm this. It would be great if the images were in colour
too. The ALPO/BAA weight=1.
