Aristarchus 1975 Dec 19 UT 22:45 Observed by Foley (Kent, England)
"Suspected anomaly in it", NASA catalog weight=1 (very low). NASA
catalog ID #1424.
On 1975 Dec ?? at 19:00UT P.W.Foley (Kent, UK), and possibly P. Moore?
(Selsey, UK) - unusual events were reported which might have been due
to minor structral changes. Albedo=76% (=7.6?). Cameron 1978 catalog
ID=1425 and weight=3. ALPO/BAA weight=1.
Aristarchus 1978 Nov 16 UTC 19:40-19:45. Observer: Mark Kidger (UK, 6"
refractor x40, x133, x200, seeing poor-boiling) - saw the north wall of
Aristarchus to be an electric blue. No spurious colour was seen in
other craters (despite the conditions). No other observers were able to
confirm this due to the weather. ALPO/BAA weight=2.
On 1975 Dec 19 at UT22:45 P.W. Foley (Kent, UK) suspected an anomaly in
Aristarchus. Cameron 1978 catalog weight=1424 and weight=1. ALPO/BAA
weight=1.

On 1975 Feb 27 at UT21:26-23:32 P.W. Foley (Wilmington, Dartford, Kent,
U.K., 12" reflector) picked up a colour Moonblink blink (brighter in
blue) in Plato crater at 21:36, 22:15 and 23:32UT extended from 11 - 3
o'clock along entire area inside the crater - the effect was
particularly diffuse and obscure, despite the surrounding localities
being sharp. The effect was seen visually and was continuous. A check
was made on star images and these were found to be very sharp and not
pulsating, thuis indicating good atmospheric conditions. This is a BAA
Lunar Section report. The ALPO/BAA weight=3.

On 1981 Oct 15 at UT06:03-06:51 D. Louderback (South Bend, WA, USA, 3"
refractor, seeing=1-2 and transparency=5) observed that the brightenss
of 4 sun lit bright spots differed in red and blue light. "Appeared as
a cross. the 2 points A & D on his sketch (index) were affceted. They
were 10 pts dimmer in red than blue. Not due to seeing as they did not
fluctuate (as did the seeing)." This report came from the Cameron 2006

On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector,
x260) saw at 01:25UT an unmistakable red-orange glow on the south and
south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected
it easily. At 01:33UT the colour was barely visible. No TLP alert was
issued because the souther edge of Mons Pico also exhibited a hint of
colour, and anyway the seeing conditions were poor. Despite this no
other features revealed colour. The Cameron 2006 catalog ID=446 and the
weight=0. The ALPO/BAA weight=1.
On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector,

obscured in detail. The variations detected were approximately 5 sec in
duration, where as seeing effects were of the order of 15 sec. Mons
Pico and other mountains did not show a similar effect. "It was seen
only in viol. filter tho once seemed blurred in red. No changes,

On 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a
darkening in the Cobra Head, Schroter's valley area of Aristarchus -
the best example that he had ever seen. The Cameron 2006 catalog ID=474
and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section
circular 1995 Oct, p125 and personal communication from David Darling
to the BAA on 6/6/1995. Note it is uncertain whether this refers to the
Clementine mission or to somebody who observed during the Clementine
mission, or somebody with that surname. Anyway if it is the Clementine
mission then the date is wrong - possibly the year should have been
1994? The Cameron catalogue does actually mention a TIFF on Clementine
mission? The Cameron 2006 catalog ID=474 and the weight=3. I am
assuming that the year should be 1994 and not 1995? The ALPO/BAA
catalog weight=1 until we can find out what the correct date is?
Aristarchus 1964 Jul 31 UT 02:00-02:23 Observed by Bartlett
(Baltimore, MD, USA, 5" reflector x180) "Deep ravine on E.glacis

On 1996 Feb 12 at UT 07:30-08:27 J.Sandel (Caycee, SC, USA)
noted a contrast effect inside Tycho at sunset. At 07:30UT there
was a slight, but definite illumination of small areas of the
crater floor west of the central; peak. Also seen by T. Ferrel
(Lawrenceville, GA, USA, SCT C8). This was oval in shape and
gray in colour - Ferrel noted some diffuseness. It brightened
over 30 minutes. At 08:11UT a definite brightness fade noted in
Tycho's central peak. The crater floor had increased
illumination of entire crater floor. ALPO/BAA weight=3.
On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52"
reflector) observed that central craterlet in Plato was
unusually bright and shows up as a bright white spot on his
sketch - though this might have been artistic license in his
sketch. His written notes refer to the unusual lack of a rim
(especially the northern part) to this craterlet.
The ALPO/BAA weight=2.

weight=3 (average). NASA catalog ID #1090.
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
into two. Gaps in the mountains were found for both streaks,
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.
In 1821 May 04 at UT 21:30-22:00 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=3. The ALPO/BAA
weight=4.
On 1989 Apr 09 at 00:00? R.Horton (N.Scituate, RI, USA, 6" reflector)

On 1989 Apr 09 at UT 00:00? R. Horton (N. ScN. Scituate, RI, USA, 6"
reflector) took an Earthshine photograph that revealed Copernicus to be
brighter than Aristarchus and Kepler. Cameron comments that usually
Aristarchus is the brighter and thought it a bit odd because Copernicus
should have been less visible, being nearer the terminator3 The Cameron
2006 catalog ID=359a and the weight=5. The ALPO/BAA weight=2.

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.
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

Aristarchus 1949 May 01 at UT 20:45 H.P. Wilkins (Kent, UK, 3"
refractor x100) observed Earthshine was very detailed and
Aristarchus was noticeably a bright patch. Upon concentrating on
Aristarchus, he observed that it flared up in brightness
considerably more still for about 2 sec. During this flare up
time, inner terraces and the central peak became visible.
Cameron says that this was confirmed by Barcroft a few hours
later???? The Cameron 1978 catalog ID=518 and Weight=5. The

obscuration" BAA Lunar Section Circular report. ALPO/BAA weight=1.
Sirsalis 1990 Mar 01 UT18:30-19:45 M. Holmes (Rochdale, UK,
21.5cm Newtonian, seeing Antoniadi I/II, Transparency very
good) was observing in earthine and saw an intense blue spot
"wink on" near to Sirsalis (sketch shows location on SE rim),
until clouded out at 18:30. When the sky cleared at 19:15UT
the spot was still visible but fainter, with a halo, the size
of Sirsalis A. By 19:35 there was a loss of detail, region
only a faint patch of light covering area twice the size of
Sirsalis crater. Clouded out permanently at 19:45UT. Cameron
2006 catalog event #392, weight=0. ALPO/BAA weight=3.
On 1967 Jul 20 at UT 07:00 Whelan, (Wellington, New Zealnd) saw a
pulsating glow from Aristarchus crater, and this continued, although
less pronounced. This was during the apolo 11 watch. The Cameron 1978
catalog ID=1172 and the weight=2. The ALPO/BAA weight=2.
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.
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 1969 Jul 20 at UT 0845 McIntosh (Auckland, New Zealand, 14"

during the Apollo 11 watch. The Cameron 1978 catalog ID=1173 and
weight=3. The ALPO/BAA weight=3.
On 1993 Dec 19 at UT 16:00-17:00 S. Beaumont (Cambridge, UK, 12"
reflector, x230) observed in Theophilus that the "c.p. > reddish brown
tint to SW (on peak?)" but suspected that it was probably spurious
colour, however no colour was seen later. The ALPO/BAA catalog ID=469

UT 21:16-21:19 Censorinus slightly brighter in red and more
detail seen. Observed other features before and after this.
Checked again UT21:31-21:40 - same appearance. Torricelli and
Torricelli B in comparison looked normal with other craters of
similar size. 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).
Drawing supplied. Cameron 978 catalog ID=1246 and weight=3. ALPO/BAA

On 1982 Jul 27 at UT 20:04 P. Madej (Newsome, Huddersfield, UK, 16cm
reflector, x33, seeing I to II, transparency fair, Hoya linear type
polarizer filter) observed that when the filter was used on Mare
Crisium, that the north part became a bright gray when turned to 45deg,
but when turned the other way it returned to normal. The ALPO/BAA
weight=3.
Large plume-like diffuse cloud over central peak, very
large compared to central peak (@ approx 30km diameter)
with intensity much different from other parts. Brightness
between walls and shadowed floor. Would take 3 minutes to
collapse, so continuously fed. 13-14 days later, at SS,
central peak was normal. Kuiper took photos after Kozyrev's
observations, but saw nothing abnormal. Drawing. Haas saw
nothing in 12inch reflector at the time. Cameron 1978

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.
Herschel 2005 Aug 13 UT 00:07-00:29 Observed by Daniel del Valle
Hernandez (Aguadilla, PR, 8"SCT, x225, S=7, T=4) "Interesting

Plato 1918 May 20 UT 18:00? Observed by Markov (Russia) "Brightness in
shadow of the light sector & 1 spot" NASA catalog weight=3 (average).
NASA catalog ID #369. ALPO/BAA weight=2.
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
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
weight=3.
1970 Jul 11 UT 20:35-20:45 During a TLP alert for Proclus, Jamieson
saw nothing unusual, but found instead that Secchi was quite bright.
NASA catalog weight=5 (very good). NASA catalog ID #1267. ALPO/BAA
weight=1.
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 1994 Apr 19 at UT 22:00 R. Knopp (Berlin, Germany) noticed a
darkening of the interior of the crater Atlas. The ALPO/BAA weight=1.
Plato 1982 Nov 24 UT 22:00-23:30. K.P. MArshall (Columbia, 12"
reflector, x100, x200, x480, seeing III, reasonably steady, but
some turbulence. No craters could be seen on Plato's floor,
despite observing conditions being acceptable. The floor was
evenly toned, and the walls were sharply defined. By 23:10 there
was a suspicion that the central craterlet was there, but he
could not quite make it out, even with averted vision. ALPO/BAA
weight=1.
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
Cameron 2006 catalog ID=332 and the weight=1. The ALPO/BAA weight=1.

USA, 31cm reflector, x420, seeing fairly good, transparency
fair) - Obscur. of floor (seen a few hours after Wilkins & Moore
obs. confirm.?) " - indeed Haas in Stolling Astronomer 2002 Vol
45, p29 states that Cragg was amazed to see Plato's floor with
absolutely nothing on it! He was able to draw details elsewhere
in other features. NASA catalog weight=5. NASA TLP ID No. #551.
ALPO/BAA weight=2.
On 1994 Apr 20 at UT 01:31 D. Darling (Sun Praire, WI, USA) found that

On 1965 Jul 08 at 01:00?UT a white streak was seen in Grimaldi,
extended towards the limb. This was observed by Rubens de
Azevedo, et. al., Brazil. The Cameron 1978 catalog ID=884 and

In 1962 Sep 09 at UT 01:42-02:00 Bartlett (Baltimore, MD, USA,
5" reflector, x180, S=5-4, T=3) observed in Agrippa the shadow
of the central peak to be grayish, not much darker than the
floor, estimated at 3deg bright, whereas on 1962 Jul 12, at col
28deg, in the 5" telescope the dhadow was anormal black and
sharply defined against the floor which was 3 deg bright. The
Cameron 1978 catalog ID=768 and the weight=4. The ALPO/BAA

level 5. ALPO/NAA weight=1 as it is not mentioned in the Cameron
catalog.
On 1986 May 18 at UT 20:45-22:25 M. Mobberley (Suffolk, UK, seeing II-
IV) found that the central craterlet of Plato was an ëasily seen "white
splodge" although it was quite difficult to see when imaged with video.
Foley and Cameron comment on IR sensitivity of the CCD camera used. The
Cameron 2006 catalog ID=285 and the weight=1. The ALPO/BAA weight=1.
On 1988 Jul 24 D. Darling (Sun Praire, WI, USA, 12" reflector,
x150, S=7/10, T=3) observed the following in Proclus: "At 0213
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
III-IV and trasnaparency good) observed a light orange transparent
cloud extending from the north east inner corner across over the floor
of Plato. Camero comments that this report was confirmed by 3 othr
observers. The shape of this clud varied. The Cameron 2006 catalog ID=
153 and weight=4. The ALPO/BAA weight=3.

Alphonsus 1966 May 29 UT 21:45-22:45 Observed by Wise (England, 4.5"
reflector, x125). and Corralitos Observatory (NM, USA). "Glint lasting
1.5s. (onset of Smith's anomaly? Specular reflection should last
longer). Not confirmed by Corralitos MB, (however they report Gassendi?
misident., or did they obs. another feature?). At UT 22:45 Smith and
Brown (England, UK, 10" reflector) observed reddish patches in
Alphonsus. Negative results from Brown though at 21:21Ut and 22:25UT).

On 1984 Jun 09 at UT 04:55-05:14 P. Jean (Outremont, Canada) detected
in the dark side of the Moon, a few km east of Kies crater, a bright
point that should not be poking out of the shadow (according to Foley).

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.
Tycho 1998 Feb 06 UT 22:48-22:54 R. Braga (Corsica (MI),
Italy, 102mm f8.8 refractor, x180, with diagonal, Wratten 23A,

refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not
visible, however Heraclides E, Helicon G, and indeed many other smaller
craters could be seen. There were two small mountains in the general
area of Bianchini G. and a mare ridge - all these were clearly seen.
Caruso states that Bianchini G should normally be much more clearly
seen than the other features mentioned and is the same size as
Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3. The

Plato 1872 Jul 16 UTC 21:00? Observed by Pratt (England?) "NW portion
of floor was hazy" NASA catalog weight=3 (average). NASA catalog ID #
179.
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 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

Aristarchus 1982 Nov 27 UT 20:13-01:00 J-H Robinson (Teighmouth, Devon,
UK) found that the bands of Aristarchus were clearer in red than in
blue light. North found that the sunlit part of the crater was very
bright. M. Cook described the crater as a "kaleidoscope of colour.

On 1997 Oct 13 at UT11:09-11:21 D. Rodway (Oamaru, South Island, New
Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in
the south east corner interior of the crater Aristarchus. This colour
was confirmed by the observers wife. By 11:21 UT the colour had faded
completely. Rodway had been a lunar observer since 1958, using a wide
range of instruments from 3 inch refractors to 12 inch reflectors and
had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so
was an experienced observer. The ALPO/BAA weight=4.
On 1963 Nov 28 at UT 05:00-06:00 Greenacre, Barr, Hall and
Dungan (Flagstaff, AZ, USA, 24" refractor) observed a deep violet
area form on the western exterior of Aristarchus, and a less deep
violet area form to the eastern edge of Aristarchus. As these
were becoming stronger, a blue-like haze formed on the sunlit
floor of Aristarchus, that obscured underlying detail. The
ALPO/BAA weight=2.
On 1985 Jun 29 at UT 22:56 M.C. Cook (Frimley, UK, seeing poor)
observed that Torricelli B looked as bright as a mountain to its south
west - no colour was seen. Cameron comments that this was similar to
Marshall's 1985 Jul 1 observation. The cameron 2006 catalog ID=278 and
the 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.
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.
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 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.
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.

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.

Conditions good, seeing 6/10) saw a small white bright point of
light appear suddenly close to the W. wall of Plato glowed
briefly as by far the most conspicuous object in the lunar field
of view and vanished quickly after approximately 2 sec. It was
star-like in appearance and was stationary on the Moon's surface

Plato and an unnamed one north west of Mons Pico. Cameron comments -
"were this & No. 429 LTP or just good seeing?)." Note it is possible
that she mean LTP 439 in which case it would refer to the previous
nights TLP. The Cameron 2006 catalog ID=439 and the weight=2. The

reflector) Taruntius faded from Vmag-3.21 to 4.04, a 0.82 difference in
magnitude in 2.5 hours - a photometric measurement. The average
magnitude for this age is 4.03, so therefore the crater had brightened
by two times above normal. The Cameron 1978 catalogID=769 and the
weight=5. The ALPO/BAA weight=3.

central craterlet was more visible in red than in blue. There was also
a streak on the floor that was "shifted to S & W." The floor was dark
and Mons Pico was bright. Peters found Plato's floor (and central
craterlet) to be dark, and darker in blue than in red, however he was
suffereing from spurious colour at his observing site. Cameron 2006
catalog ID=111 and weight=0. ALPO/BAA weight=1.
On 1980 Sep 25 at UT 20:20-22:14 Peters (Kent,UK, x240 and x120,

On 1984 Nov 10 at UT19:15-19:50 R. Moseley (Coventry, UK, the Moon's
altitude was low) noticed that the region from the central peak and
over and onto the east wall looked unusual. 8 bands were visible, "two
on E. wall of c.p. strongest, surrounding collar grey increasing
intensely outward. Band at 2 o'clock position was very dark. Bright
spot on W. wall at 4 o'clock position." A sketch was made that

refractor, x128 & x160, Seeing III, transparancy average)
suspected on the eastern edge of Geminus, on the border of the
crater filled shadow and the eastern illuminated rim, a
brownish, almost speia hue. This extended for a short distance
from the floor shadow into the illuminated rim width and spanned
