On 1971 Feb 27 at UT 23:50-00:00 Dezmelyk (Newtown Square,
Pennsylvania, 2" refractor, x225, x500, seeing=good) observed in
Earthshine a peculiar white glow too far from the terminator to be
sunlit. 9 minutes later they could not detect this, nor any other
spots. The spot concerned was about 8-9th magnitude - "like galaxies".
They checked the lens for dirt but it was clean. A drawing was
provided. The Cameron 1978 catalog ID=1285 and weight=2. The ALPO/BAA
weight=2.

seeing=good) saw an intense star-like point of 9th magnitude, with no
angular diameter, 4-5x brighter than the surroundings in Earthshine.
The observer did not think that it was a TLP, but Cameron considers the
report is similar to many other TLP descriptions of Aristarchus in
Earthshine. Marks (England, UK) who was observing at 20:20UT did not
note anything unusual in Aristarchus. The Cameron 1978 catalog ID=1121
and weight=3. The ALPO/BAA weight=1.

Ptolemeus 2020 Jul 27 UT 23:00 N. Travnik (Brazil) observed
visually for 2nd time ever (first seen back in 1970), an
effect on the floor of this crater at local lunar sunrise:
"kind of glimmering mist lifted and wafted inside the shady
hollow of the crater". Almost certainly this is a combination
of atmopsheric seeing on the narrow shadow spires, but we
would like observers to look at this visually or obtain time
sequence images to try to replicate this effect. This report
is assigned an ALPO/BAA weight of 1 for now.
On 1993 May 28 at UT 21:02-21:30 M.C. Cook (Frimley, UK, 3.3" Questar
telescope, x80-x130, atmosphere hazey - poor transparency) noticed that
the east side rims were slightly fuzzy and suspects that this might
have been due to the illumination angle. A.C. Cook (Frimley, UK)
obtained some CCD images that revealed that the effect was to some
extent still there one hour later. The Cameron 2006 catalog ID=461 and
the weight=5. The ALPO/BAA weight=2.

4" refractor, x95, seeing=1-2-1 and transparency=4) detected a change
in brightness of Mons Piton point D (his designation) during 04:56-
04:59. The whole of the east slope was affected - initially bright and
then faded and there was a blue colour (detected with filters). The
variabilty was 8-11sec (Cameron suspects atmosphere as the altitude was
low). The brightness stabilized at 05:12UT, but variability resumed
until observing finished. As a comparison Aristillus was not seen to
change. The Cameron 2006 catalog ID=287 and the weight=1. The ALPO/BAA

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 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 1988 Jul 25 at UT03:15 H. Davis (Madison, WI, USA) stated that
Proclus was normal apart from a "slightly darker area in SW (Ast) SE
(IUE) corner." The Cameron 2006 catalog ID=334 and the weight=0. The
ALPO/BAA weight=1.
Callipus and vicinity 1973 Feb 13 UT 23:16-23:50 Observed by Frank
(E.Pepperell, Massachusetts, USA, 6" reflector x100, Seeing=good,
altitude=45 deg). "Large dark patch, albedo=3 present E. of Calippus.
Drawing. (Shows it into Callippus also). Never seen before or since.
Albedo normal (4.5) at 2350h. (obs. monitors Callippus in ALPO-LTP

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.
Aristarchus 1971 Mar 08 23:00-23:10 Observed by Lyttle (Northern
Ireland, 6" reflector, x98) "Suspicion of white spot W of N-S radial
band, slightly brighter than wall. Diam. @5-6km. Area affected by temp.
?Term. passed over it just 5h before. Gradual decline in brightness
over the 10m period." NASA catalog weight=1 (very low). NASA catalog ID
1288.
On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in
Gassendi - some obsevers detected colour, others did not. P. Moore did
not notice anything unsual earlier at 18:50-19:00, though his seeing
was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing
was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also
reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did
however notice a small reddish spot to west of central ridge, but by
20:30UT the colour was less obvious, but the spot was back again at
20:45, but not easily seen at 21:00 and gone completely by 21:45UT.
N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red
patches on the floor between 20:54 and 21:31UT. A BAA Lunar Section
report. ALPO/BAA weight=3.
On 1963 Nov 28 at UT 00:30-01:45 Barr, Greenacre, Hall and
Dungan (Flagstaff, AZ, USA, 24" refractor, and 69" reflector)
observed pink on the outer SW rim and a red spot towards the S of
this. A red spot was seen on the eastern side of Vallis Schroteri
but only by Barr and Dungan. Other features checked for
atmospheric spectral dispersion and chromatic aberation - but the
colours in Aristarchus were not due to these. Smaller 12" scope
checked but no effects seen - presumably due to resolution and
image contrast issues? Pink on the SW rim may have been seen in a
69" scope by Boyce and Ford. ALPO/BAA weight=4.
On 1980 Aug 22 at UT20:15-21:29 J-H Robinson () detected violet on the
west wall of Aristarchus. Cameron 2006 catalog ID=105 and weight=5.

On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK,
12" reflector, x200, seeing=II) noticed in the area south east of
Manilius that it was brighter in red light than in blue light at
20:15UT whereas 1 minute later it was the same brightness in each
filter. The effect reappeared at 20:21UT and was particularly strong at
20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was
of high reflectivity in white light and was bright in red at 21:15UT,
thougjh the south east area stopped giving a colour reaction at
21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT
however at 23:55UT it was surrounded by a transient white ring that
varied in visibility in an irregular way. Foley found Manilius B had a
vivid blue interior and in blue light the ring was black. and not at
all seen in red or white light. The CED brightness measurement varied
from 1.9 to 2.4. All other regions observed were normal in brightness.
Violet was seen on the west wall of Aristarchus though. M.Price
(Camberley, UK) found a possible blink in Manilius B but was observing
under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5.

Argentina, 105 mm Maksutov-Cassegrain, x154, seeing 6/10, some
interuption from clouds) observed a light spot SE of the
centre of the floor of the crater, which came and went in
visibility. There is a light spot here, but what was unusual
was that the visibility decreased over time.
ALPO/BAA weight=1.
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 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector,

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

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 1988 Apr 01 atUT01:15-03:20 H.Hill (Lancaster, UK, 10" reflector,
x286) observed that east of Lichtenberg were ëxtensive rosy areas"
around the northern edge of the lava sheet. Hill believes that it may
have been the same effect as seen by Madler (Germany), Barcroft (USA)
and Baum's (UK) 1951 observation. The colour was "ünmistakable" and
nothing to do with the atmospheric spurious colour. Other features were
checked. the cameron 2006 catalog ID=322 and the weight=3. THe ALPO/BAA

reflector, x200, Wratten 25 and 44A filters, seeing II-III,
transparency, good) noticed in Aristarchus, blue to the north west
(IAU?) internal wall, also blue observed in other small bright objects
against dark backgrounds. Lunar rotational axis and optical normal
related such that the normal runs NW-SE (IAU?) through these features.
Observer deduced that the coliur was obviously spurious and no blink
was seen in any feature. The blue disappeared as the lunar altitude
increased and no blue seen by 00:00UT. This is a BAA lunar section
observation. The ALPO/BAA weight=1.
On 1992 Jan 18 at UT 22:34-23:48 A.C. Cook (Frimley, UK, 8" reflector,
seeing=III) was able to see 4 craterlets and two rays on the floor of
Plato. This was suprising because Moore, using a larger telescope and
magnification, was unable to see any detail here on 1991 Dec 12th at
02:10 - according to Cameron. The Cameron 2006 catalog ID=438 and the

On 1970 Aug 17 at UT 02:40 Pedler (England) noted that the
shadow flowed around instead of over Plato. Wondered if shadow
matched the gray of the crater. Within minutes the shadow line
looked normal again. At 04:41UT Claudio Pamplona (Brazil) saw a
pulsation in Plato during a lunar eclipse. He thought that this
was due to falling temperatures. The Cameron 1978 catalog ID=

2045 reflector, x40, seeing=turbulent) detected flashes coming from
just north of the centre of Mare Tranquilitatis. Some of these flashes
were of a duration of seconds whilst others were several minutes.
Altogether ~20 flashes were seen, and not in the same place. "5 small
star-like points could be located - and there were lots of craterlets".
The spots were "lined up E-W at N of 10 deg latitude." Colour was not

Aristarchus 1983 Oct 23 UT 19:00-01:30 Observer: Foley (Kent, UK,
12" reflector, seeing=II) noiced at 19:00UT an extended bright
spot on E wall and extending beyond. This was brighter than other
areas of the crater. There was also occasional star-like
glistening. Foley comments that the inside of Aristarchus was
slightly obscured. The TLP started fading from UT20:30 and
finished by 01:30UT. six out of nine independent observers
confirmed the effects seen. In total 14 observers observed, 9
reported back and 6 found abnormalities in Aristarcus though all
encountered variable seeing conditions - some had spurious
colour. Cameron comments that this was one of the best
recorded/confirmed TLP events. All CED brightness measurements
obtained were very high. Moore, Nicolson and Clarke (5" refractor
and 15" reflector, 230-350xseeing III) found the crater to be
very bright at 19:11UT through a 5" refractor and there was a
blob on the east rim (Bartlet's EWBS?) at 19:14UT. Nicolson also
saw a very bright star-like area on the eastern wall but this was
not defined as it usually is. The crater was also very bright at
22:43UT using the 15" reflector available to these observers. At
01:07UT they used a Moon blink and discovered that the bright
region was bright in blue light and less bright in red - although
this was not a detactable blink when switching rapidly between
filters. They found that the crater had returned to normal by
01:15UT. M.C. Cook (Frimley, UK, seeing III-IV) observed a large
diffuse spot on the east of the crater that was brighter in blue
than in red light and the CED device gave a high reading. J.D.
Cook (Frimley, UK, seeing III-IV) made a skecth that showed the
bright spot extended on the east wall - again the CED reading was
high and a lot of detail was visible on the floor. A.C. Cook
(Frimley, UK, seeing III-IV) also noted remarkable detail and the
bright (as confirmed by CED) blob on the eastern rim. G. North
(Sussex, UK, seeing III-II) also confirmed the bright blob on the
eastern wall. Wooller found the north west wall was a dirty
yellow colour - though no colour was seen elsewhere in or outside
the crater. Mosely found the crater to be bright and his sketch
revealed the extension of the bright blob on the eastern rim and
again a great deal of interior detail. Amery (Reading, UK, seeing
III) found Aristarchus to be "a brilliant splash against dulled
background in violet filter, especially polarizing filter. CED +
polarizer readings high, but not as high as previous night".
Mobberley (Suffolk, UK, seeing III-IV) remarked that "spurious
colour a total mess around Aristarchus & nothing abnormal seen".
A photograph was taken at 20:50UT reveals the bright blob and
entire detail. Peters (Kent, UK, seeingIII-II) observed
Aristarchus with a UV screen from 20:15-21:23UT and comented that
althogh being very bright, there was no variation between white
and UV. It was checked with a Moon Blink device and the radial
bands were clearly seen in white light, < in blue. The Cameron
2008 catalog ID=233 and the weight=5. The ALPO/BAA weight=4.

Macrobius 1971 Mar 15 UT 02:07-03:15 Observed by Sparks (Exmouth, UK,
6" reflector x400) "Strong pink color extending whole curve of crater's
illum. wall, starting & ending in shadow side. Color grew deeper, then
faded & ended at 0315h. Changed eyepieces. No other feature had this
tho. looked for. Survived many separate powers of eyepieces."

In 1965 Jul 02 at UT 04:20-05:50 Albert and Welch (Azuss, CA, USA, 8"
reflector, x375) and Emanuel (West Covina, CA, USA, 4.5" reflector)
observed 4th magnitude star-like flashes to blotches in Aristarchus, in
ashen light. Cameron says that this is independent confirmation and
also that the date in MBMW is 7/1/65 which is local time + 2nd UT. The
Cameron 1978 catalog ID=881 and weight=3. The ALPO/BAA weight=3.
Picard 2002 Sep 10 UT 02:30-03:21 Observed by Gray (Winnemucca, NV,
USA, 152mm refractor x248,S=2-3, T=5) "observed in White light and
through Wratten Red 25 and Blue #38A filters. The crater through the
Red 25 filter looked very similar to the view in White light. Using the
Blue 38A filter Picard almost dissapeared - it looked like a dim,
faintly observable black spot with the sunlit, east facing west crater
wall barely visible. Observer had not observed Picard very often, so
was not too familiar with it but it seemed odd that it almost vanished
through the blue filter." ALPO observational report. The ALPO/BAA
weight=3.
On 1788 May 08/09 at UT 20:00-01:00? Mechain (France) observed bright
spots near Aristarchus. This was confirmed by Schroter and Bode
