Proclus C region 1985 May 23 UT 17:41 Photographed by Kolovos (observer
from Thessoloniki, Greece, observing site near Bafra Serrain, Greece,
4"refractor, seeing excellent) "Observer took a series of expousres on
a portable scope of the Moon. On one of them a very bright slightly
elliptical spot was seen. Spot was very close to the Proclus C crater.
Upon analysis it was claimed that the spot of light had rotated the
direction of illumination of shadows in adjacent craters - however
subsequent analysis casts doubt on this. Papers on this report
were published in Icarus. Rast and Maley suggested that it was sun
glint off a spinning US ex-military weather satellite that just by
chance came across the field of view of the Moon a few tens of seconds
around the time of the photographed flash. Was this a coincidence or
not? If it were a satellite sun-glint then the satellite would have to
be tumbling incredibly fast in order for the flash to be so sharp in
the photograph - so the satellite explanation is not completely 100%
confirmed." The Cameron 2006 catalog ID=273 and the weight=5. The
ALPO/BAA weight=2.
In 1949 May 02 at UT 03:30-04:00 Barcroft (Madera, CA, USA, 10"

10" reflector, x150, seeing=IV-V) could not distinguish between Messier
and Messier A. The tail of these features was very bright - two
telescopes were used. Moore (Selsey, UK, 12" reflector, seeing=III)
could see Messier A but found Messier itself obscured - just see the
west wall and thought that the comet like tail was unusual as it did
not appear divided. The Cameron 2006 catalog ID=192 and weight=5. The

On 1982 Jul 28 at UT20:38-20:48UT A.C. Cook (Frimley, Surrey, UK, 12"
reflector, seeing IV-V, some spurious colour prsent) observed that the
central peak of Alphonsus was brighter in red light than in blue, so
much so that at the start of the session the peak could hardly be seen
in blue light. The central peak varied in brightness in red light but
not in white light. The central peak of arzachel was brighter than that
of Alphonsus in white light but had no colour - Arzachel's central peak
did however appear to fade in brightness over time (or was it Alphonsus
getting brighter?). Cameron 2006 catalog ID=177 and weight=3. The

On 1975 May 18 at UT2115-2145 C. Lord (St Annes-on-sea,
Lancashire, UK, 76mm f/16 refractor, x170, Wratten 25, and 44a
Moon blink filters used, Transparency 4.5/5, no wind, S=F). The
west flank of Maginus, and the interior, appeared to be partly
obscured. No other features in a similar position along the
terminator were obscured. No colour blink was detected with the
filters, though a pronounced red/white light blink was noted; the
device employed a N.D. x4 filter. By 21:45UT the floor was no
longer obscured and only Magninus G was masked in a white haze;
however immediately adjacent to the terminator was an ill defined
misty patch lying where the outer flank of maginus would have
been visible. The rest of the terminator was sharp. The
obscuration was only seen to advantage in blue and int. light,
and the blue/int blink was only very slight. Findlay and
McDonnell observed 21:30-23:00 using a 25cm refractor (Seeing II-
III) but failed to see anything unsual. NASA catalog weight=3.

77mm refractor, x83,x250, seeing II-III, transparency fair).
After studying the whole length of this valley, the observer saw
a change in "albedo" and a small change in colour of the valley
floor near to the Plato end. This colour was not seen in a
yellow Wratten 15 filter but was noted in a purple Wratten 35
filter, and was strong in a red filter. Also the crater
Trouvelot was not seen at x250 with a x2 Barlow.Wratten 25.

observed a strong beacon like flash in white light that moved back and
forth in the east wall of Plato (very bright) and Mons Pico. tried
changing eyepiece and the field of view, but this wasn't the cause of
the effect. A check at 11:07UT did not show the effect, but it was back
again by 11:18UT being more pronounced at Mons Pico than the east wall

Mosely saw a reddush-orange patch and this was confirmed by
Moore. NNW of the central peak, Mosely got a blink, but Moore
did not because of too much stray light. The colour was like
Jupiter's red spot, but less pronounced. The Cameron 1978

On 1974 Jan 03 at UT 18:30 a Norwegian amateur astronomer,
Hoydalsvik (Hakonsgate, in West Norway, 60mm refractor)
photographed the Moon using High Speed Ektacrome (400ASA) film
with good focus. The TLP was located on the southern slope of
Sasserides H and was pink in colour with some bluish in it.
The coloured area was circular with a diameter of 0.5 minutes
of arc. Only one exposure was taken. The photograph was
checked by the Institute of Theoretical Astrophysics,
University of Oslo. Although they thought it was probably
genuine (could have been an impact flash?) suggestions by the
BAA lunar section favoured static electrical discharge on the
film. It is uncertain whether the film was ever examined by a
Photographic developing lab such as Kodak, who would be able
to tell if it was real or an artefact. ALPO/BAA weight=1.
On 1984 Jun 09 at UT 04:55-05:14 P. Jean (Outremont, Canada) detected

England, 8" reflector x220) "Red color No. of landslip in W. wall seen
in blink & vis. Vanished by 2105h. Had not returned at 2125. (Moore has
wrong date in his extended catalog.)." NASA catalog weight=3. NASA
catalog ID #1074.
Archimedes 1971 Aug 01 UT 22:00(?) (19:00 originally given
probably local time) Miranda (Plaui, Brazil, 4" refractor,
x80) observed two grooves going from east to west, broadening
towards the west, across Archimedes. A drawing was supplied.
Apparently this was the first time that this was ever seen.
Cameron suggests rays? and also says that in fact a similar
phenomenon reported before in neasrly the same position
(Apollo 15 watch?). The Cameron 1978 catalog ID=1303 and
weight=2. The ALPO/BAA weight=1.
South of Copernicus 1972 Feb 24 UT 19:30-20:00 Observed by McConnell
(England, 6" reflector, x195, seeing=good) "White spot just S. of Cop.
about same size as Copernicus H (@ 5km), (there is a bright area or mt.
SW of Cop. H)." NASA catalog weight=1 (very low). NASA catalog ID 1323.
On 1994 Apr 21 at UT 06:00 W, Cameron (Sedona, USA) detected a reddiah
colour on Pronontorium Laplace, This is TLP event No. 9 in the ALPO
Clementine LTP program Nov 1994. The ALPO/BAA weight=2.
On 1955 Jan 05 at 01:00-01:30 UT D.A. Logue (Larchment, PA,
USA, 15cm reflector at x340, seeing Good) saw a strange blue
light above the surface of the Moon where the night and the
day meet. He observed this light for more than 30 min and it
did not appear to move. It appeared like a star in that the
rays of light came from it. The observer adds that he first
thought thst the objects was a star, but later decided that it
had to be on the Moon itself. A drawing shows the blue spot
near the rugged south west (IAU?) limb of the Moon. The editor
of the Strolling Astronomer (Vol 8, No. 11-12, Nov-Dec 1954,
p146) was unable to identify the craters drawn. The editor
speculates that the observer saw a high mountain peak with its
summit in sunlight and detached from the illuminated regions -
however this would not explain the blue colour. Note this is
an ALPO observation and does not apear in the Cameron
catalogs. ALPO/BAA weight=2.
On 1964 Jun 21 at UT 03:43-05:44 Harris, Cross and Helland (Whittier,
CA, USA, 19" reflector) observed south of Ross D: "Moving dark area".
The Cameron 1978 catalog ID=819 and weight=4. The ALPO/BAA weight=4.
On 1982 Aug 01 at 00:00-01:00 K. Marshall (Medellin, Columbia, 12"
reflector, seeing I-II) noted shading on the east floor of Plato that
was apparently lighter than the rest of the floor and this was seen at
both low and high magnifications. Foley notes that this was unusual.
There were three craterlets visible on the floor - the central one was
the brightest. Cameron 1978 catalog ID=178 and weight=3. ALPO/BAA
weight=1.
A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and
definition fairly good. Observer noticed that the Mare seemed covered
with a close network of innumerable streaks, and spotted with countless
numbers of light specks, so that it would hardly be possible to
delineate them all in one night. The spots and streaks together must
have numbered ~1000. The observer had never seen anything like the
number of spots and streaks. Peirce A, was not at all easy to see and
neighboring spots almost as bright made it difficult to distinguish
which one was Peirce A. ALPO/BAA weight=3.
On 1976 Apr 10 at 21:15-21:49UT S.Spencer (60mm refractor x60, seeing
quite good) noticed a faint red glow at the south west wall of Gassendi
covering a span of about 35 deg arc. The observer had some doubts about
this because they were using a small telescope, but thought that they
ought to report it, just in case. A BAA Lunar Section report. ALPO/BAA
weight=1.
On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector)
and at the same time Doherty (Sussex, UK, 15" reflector) observed a
strangely bright and pink/red north rim of Aristarchus crater during
UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT.
M.C. Cook (Frimley, UK) found the northern wall to have a red/purple
colour but the effect vanished after 50 minutes. Cook also saw a "V"-
like notch in the NW crater shadow and this appeared to be bigger than
normal. G. North (Sussex, UK) saw a tinge of pink colour on the
northern rim and a bit later a "ruby red" colour on the north-west wall
- again this effect lasted 50 minutes. Moseley verified the colour.
Finally M. Hather (Yorkshire, UK) suspected the north wall of
Aristarchus to be blue in colour. Cameron suspects that this TLP is not
spurious colour because it is in the wrong place. The Cameron 2006
catalog ID=276 and the weight=5. The ALPO/BAA weight=4.
On 1985 May 30 P.Madej (Huddersfield, UK, 77mm refractor, x111
and x250, seeing II-III, transparency good) whole spectrum of
colours seen on the central peak area, visible in both
eyepieces, and was more prominent at the higher magnification.
Not aware if the observer checked for this effects on other
terminator peaks? xALPO/BAA weight =1.
On 1991 Jan 26 at UT 23:38-23:50 D. Darling (Sun Praire, WI,
USA, 12.5" reflector, x159 and 3" refractor x90, seeing 5/10,
transparency 3/6) found that Aristarchus was brighter through
a red filter than through a blue filter on its western wall.
He checked Aristarchus in two telecopes and obtained the same
result. The Cameron 2006 catalog ID=419 and the weight=4. The
ALPO/BAA weight=3.
On 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector,
seeing III-IV) found that LaPlace A was significantly more prominent
than usual - comparisons were made with photographs in books. The
Cameron 2006 catalog ID=178 and weight=3. The ALPO/BAA weight=1.
Proclus 1990 Mar 09 UT 00:12-00:13 Observed by Marie Cook (Frimley, UK,
3.5" Questar telescope) observed a "long plume of light" the brightness
was the same as the wall region. It went from the southern rim about
half of the way across to the centre in the "northerly". The plume
feature was not seen at higher magnifications. Change in brightness
also noted. The Cameron 2006 catalog ID=394 and the weight=1. The
ALPO/BAA weight=1.
On 1993 Jun 02 at Ut 04:30-05:45 S. Beaumont (Cambridge, UK) saw that
the shadow of the Cobra's Head in Schroter's Valley was lighter and
more diffuse seen at user defined locations of C or B rim (these were
black versus medium gray for Cobra's Head). The TLP had vanished by
05:45UT. The Cameron 2006 catalog ID=462 and weight=3. The ALPO/BAA
weight=1 because the date or time is wrong.
On 1984 Nov 05 at UT18:00 Marshall (England) noted that there was no
normal brightening on the floor just next to the southern most
craterlet. The Cameron 2006 catalog ID=251 and the weight=2. The
ALPO/BAA weight=1.
On 1994 Apr 23 at UT02:41 D. Fryback (Madison, WI, USA) observed a
starlike flash in Alphonsus crater. The ALPO/BAA weight=2.
On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit
around the Moon, obtained images of the Cobra Head region of
Aristarchus crater that suggested a ~15x colour ratio increase (0.4
microns / 1.0 microns) in comparison with images obtained on 1994 Mar
03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting.
However it was later suggested that this was due to incorrect
radimetric calibration procedures being followed. The ALPO/BAA
weight=1.
Aristarchus 1965 Nov 06 UTC 03:20-03:50, 05:50 Observed by Bartlett
(Baltimore, MD, USA, 3" refractor x300, S=6, T=5) "Strong blue-viol.
glare on E. & NE wall; dark viol. hue in nimbus. (absent at 0320-0350.
Listed as 11/8/55 in both ref. 210 & MBMW, but should be 1965). NASA
catalog weight=4, NASA catalog ID #911.
On 1985 May 31 at UT 20:23-22:00 G. North (Sussex, UK, turbulent
seeing) found Torricelli B at 20:23 to be mauve in colour and to be
very bright. However the colul had gone by 20:29UT. "Varied in albedo
2s then image blurred at 5-10s (atm) at 2034 became pink). At 21:35UT
M. Mobberley (Suffolk, UK) found a white patch in the crater centre and
a mag 8 flash was seen (confirmed independently by a 2nd observer ~
113km away)- there was no shadow. At UT 20:30 P.W. Foley (Kent, UK,
12"reflector, seeing excellent) found no colour, but the brightness was
changiong and he confirmed the bright patch on the crater's floor,
variable 22:15-22:25UT, "then expanded over rim". The Cameron 2006
catalog ID=277 and weight=5. the ALPO/BAA weight=4.
In 1950 Aug 25 at UT 10:55 T.Saheki (Osaka, Japan) observed a
stationary yellow-white flash on the Moon of duration 0.2 sec
and mag 6.5. Cameron suggests that this was a meteor. The
Cameron 1978 catalog ID=536 and weight=0. The ALPO/BAA weight=1.
On 1964 Jun 23 at UT 04:45-05:05 Bartlett (Baltimore, MD, USA, 5"
reflector, x180, S=4-1 and T=3) observed a blue-violet glare on the
north east rim and a strong violet tinge in the nimbus. The effect was
absent 1 hour earlier. The Cameron 1978 catalog ID=821 and weight=4.
The ALPO/BAA weight=2.
Colour seen between Aristarchus and Herodotus by P. Moore
and G. North. ALPO/BAA weight=3.
Aristarchus 2015 Mar 03 UT 23:58 Brendan Shaw (UK) saw a flash
on the NW rim of Aristarchus on his computer screen - the camera
was working in the near IR. Seeing was not very good at the
time. Unfortunately this flash occurred in between imaging
sessions. No other flashes seen, despite looking. The observer
considerd the possibility that it might have been a cosmic ray
detection, but cannot say for sure. The ALPO/BAA TLP weight=1.
On 1994 Apr 24 at UT 03:50 R. Manske (Waunakee, WI, USA) found that the
Cobra Head appeared to have an obscuration on the top eastern half. The
ALPO/BAA weight=2.
Riccioli 1974 Jan 07 UT 16:30-17:00 Observed by McKay (South Downs,
England, 3" refractor, x135, S=IV boiling) "Bright spot and dark patch
changing in size (atmos. aberr. ?)" NASA catalog weight=1 (very low).
NASA catalog ID #1385.
On 1893 Sep 25 at UT 21:00? Gaboreau (Paris, France), saw a shaft
of light projecting from the Moon. Cameron 1978 catalog ID=281
and weight=0. ALPO/BAA weight=1.
40.5W, 45.7N 1965 Nov 09 UTC 04:59 Observed by McCord (Mt Wilson, CA,
USA, 60" reflector + spectrograph) "Line depth anomaly, low compared
with 23 other areas". NASA catalog weight=5 (very high). NASA catalog
ID #912.
Aristarchus 1983 Oct 22 UT 22:00 G.W. Amery, (Reading, UK, Seeing
III-IV) found Aristrachus so bright that the CED was unable to
give a reading. The crater's interior was also diffuse in
appearance. The Cameron 2008 catalog ID=232 and weight=4. The
ALPO/BAA weight=3.
