On 1978 Mar 13 at 17:25UT V.M. Chernov (Soviet Union) observed that the
northern cusp was elongated into Earthshine, 4.6 days after New Moon.
One day before this the cusps appeared nromal to him. The ALPO/BAA
weight=1.
On 1968 May 02 at UT 01:20-02:14 Doughty (Red Bank, New Jersey, USA,
8" reflector, x120) observed a bright area in Aristarchus, surrounded
by a faint glow. May have been atmospheric dispersion. Glow fainter at
01:56UT and imperceptible at 02:14UT. Kelsey and Ricker consider the
observation abnormal. The Cameron 1978 catalog ID=1070 and weight=3.
The ALPO/BAA weight=2.
On 2012 May 25 UT 05:35 Brenner F crater was recorded in a larger
area image by M. Collins (Palmerstone North, New Zealand, ETX-90
with LPI imager (monochrome mode) - seeing not good). He took a
sequence of 108 images from 05:35-05:40UT, and in the 65th frame,
a light spot, approximately 4 pixels wide can be seen just
outside the western illuminated rim of Brenner F. It is not
visible in any other frames. The exposure time was 0.125 Sec.
Because the western edge of the spot is very sharp, and the rest
of the Moon is slightly blurred due to seeing, it is thought that
this was most likely a cosmic ray event in the CCD camera - the 4
pixel width was perhaps contributed to by the image compression.
It could also be some bright surface spot that was made invisible
most of the time by poor seeing, and then during a brief period
the atmosphere is sharp enough at that locality to make it
visible. ALPO/BAA weight=1.
On 2009 Jan 30 ay 22:35:20UT +/-2 min R. Masini (Perth, Australia) saw
a bright clound just west the south pole and along of the southern
limb. The effect lasted a few seconds and faded. It was seen with the
naked eye. There was a grazing occultation of a 6th magnitude star from
this site, however the star would have been in the wrong place at the
time of the TLP. The ALPO/BAA weight=2.
On 1992 Dec 29 at UT 17:42-17:54 A. Dollfus (Meudon, France, 1m
aperture telescope used) detected evidence for a dust cloud using CCD
polarimetry. The ALPO/BAA weight=5.
On 1984 Nov 28 at UT 17:30-18:05 P. Madej (Huddersfield, UK) found that
the crater Hubble had a cream white oval patch for short while that was
2x brighter than it's surroundsings. The Cameron 2006 catalog ID=254
and weight=3. The ALPO/BAA weight=2.
On 1891 Nov 07 at UT=19:00 d'Adjuda of Lisbon, Portugal (seeing fair)
whilst observing Aristarchus noticed that the crater appeared as very
distinct luminous point in the dark. Cameron 1978 catalog ID=275 and
weight=3. ALPO/BAA weight=1.
Messier 1981 Feb 10 UT 19:20-20:10 TLP discoevered by Hedley
Robinson (Devon, England) "Messier was brighter than Aristarchus
in both red and blue filters and also appeared indistinct, later
becoming invisible - lost in a bright streak. In comparison
Aristarchus was clear. Another observer, Amery confirmed that
Aristarchus was sharp in appearance but Messier certainly was
not. Cook likewiese found Messier not to be as sharp as Messier
A dueto a big shadow in Messier A. Pedler found that the sun
facing wall of Messier was OK but that the shadow was changing
from black to grey periodically at intervals of 2-3 minutes to a
few seconds. By contrast he found that Messier A remained quite
well defined. He tried red and blue filters but found no blink
effect. At 20:23UT Pedler found that the shadow had stabilized
to a shade of "mid grey" although remaining ill-defined. North
also found that Messier A was distinct but Messier itself was
ill-defined. Moore found the same thing but thinks that this is
normal for Messier under this illumination to appear indistinct.
More also saw the grey interior shadow. Price saw similar
appearance to Moore and suspected that this was normal for this
stage in illumination. Ratcliffe suspected everything normal -
just commenting that Messier was smaller and no detail in
comparison to Messier A. Madej and Taylor provided a sketch that
showed again a grey interior and merging with the east
wall/mare. Foley found Messier's pale grey interior to be un-
focusable but in comparison Messier A was sharp. He says that he
would expect a grey interior and the east wall to merge with the
mare. However the complete loss of deatil and variability were
not normal. Cameron comments that the Kuiper atlas confirms the
fuzzy indistinct appearance of Messier and that a Lunar Orbiter
picture shows a grey shadow. The Cameron extended catalog
weight=5. The ALPO/BAA weight=2.
On 1992 Dec 30 at UT 17:36 A. Dollfus (Meudon, France, 1m aperture

Alphonsus 1990 Feb 03 UT 18:00-18:23 Observed by A.C. Cook
(Frimley, UK, CCD video camera, seeing III-IV). At 18:06 W and
SE dark floor patches, equally dark, but at 18:10 and 18:23 the
W dark patch was the darker of the two?. Between 18:06 and 18:23

On 1984 Dec 01 at UT 20:00 a British Astronomical Association Lunar
Section member (Southam, Warwickshire, UK) found no detail on the floor
of Autolycus, despite there being plenty of detail on the floor of
Aristillus crater. According to Foley, there should be some detail at
this stage of illumination. Grego reports that the observation was from

On 1977 Apr 29 at UT21:40-23:20 an unknown UK observer reported a TLP
in Gassendi crater. The following are reports by observers attempting
to confirm activity: J.W. Napper (Didcot, UK, 30cm reflector, x287,
Wratten 25 and 44a, conditions clear 5+) received a telephone alert
call at 22:00 but the sky was cloudy until 22:30. An initial look
revealed nothing unusual, then at 22:54 he observed a colour blink just
inside the north wall, appearing bright in red and normal in blue or
white light. No loss of detail seen and the effect lasted only 2
minutes. A sketch was made. However the observer stresses that the very
bad seeing casts some doubt on this observation. L. Fitton observed
using a 8.5" reflector, with Moon blink device at x200, seeing was I-
II. All areas negative, including Gassindi from 21:40-21:55 and again
22;00-22:25 and finally 22:50-23:30 negative. Mike Brown (Huntington,

cirrus) observed visually (depicted in sketch) the two closely
spaced NW wall dark bands) to have a rusty-red hue. The colour
of these bands did not change over the period of the observing
session. Images were taken, but resolution and image S/N is
not sufficient to resolve separate bands here, or to detect
colour. The ALPO/BAA weight=1.

Gassendi. 2023 May 02 UT 01:35-02:23. J. Albert (Lake Worth,
FL, USA - ALPO. 8” SCT via a 9mm ortho eyepiece. Transparency
magnitude 3 and seeing was 7/10) checked the crater without
filters as well as comparing with W25 red and W44A blue
filters using 226x. He saw no color on the SW part of the
crater floor or on the NW wall. Using the filters, however,
he did note that the high peak on the S wall was brighter in
blue than red. He tried this filter blink a number of times
because he had never seen this before in Gassendi, but the
result was the same each time. A colour image was taken
earlier at 01:21UT but shows not colour on S wall as it was
saturated. ALPO/BAA weight=2.
Gassindi 1966 Oct 25 UTC 22:30-23:10 Observed by Moore and
Moseley (Armagh, Northern Ireland, 10" refractor) and Sartory

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

west wall of Aristarchus. Cameron 2006 catalog ID=105 and weight=5.
ALPO/BAA weight=2.
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.

On 1964 Jun 21 at UT 21:18 Lipskii and Pospergelis (Shternberg State
Ast. Institute, AZI-2" reflector (Cass.) observed Aristarchus:
"Polarization meas. with electron polarimeter. Plane of polariz.

Piton at 23:00. Photographic atlas was checked to verify that this was
abnormal. The Cameron 2006 catalog ID=193 and weight=4. The ALPO/BAA
weight=2.
On 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st
7:24PM PST) saw a naked eye flash on the Moon. The observers were
glancing up at the Moon in daylight when they saw a bright white flash
(observer and his wife together) in the upper/mid Mare Serenitatis
region, west of the crater Posidonius. "Larger than how Venus appears".
"It was a quick flash like white, intense lightning. I'm not sure how
to report degrees of arc but if the face we see is 900, and we start
from the east then the flash occurred about 225 arc seconds to the
west. This was observed by the naked eye, with clear skies between us
and the moon." The observers checked for signs of aircraft vapour
trails but could not see any. There is a possibility that it could have
been sun glint from an Iridium satellite, but this needs to be checked
out and usually these last longer than the observed effect. It would be
useful to obtain whole Moon images under the same illunination and
libration so that we can judge this observation properly. The ALPO/BAA
weight=4.
Herodotus 1965 Jun 11 UTC 21:35-21:40 Observed by Porta, Garau

Aristarchus. 2024 Mar 22 UT 22:08. G.Vega (Argentina, Oro
Verde - 20cm f/5 Newtonian on an EQ5 Goto mount - two colour
cameras used: a Player One Ceres C & a Nikon D5100).
Colour images show a region of blueness from the W. rim of
Aristarchus and the NE of Herodotus (maybe also on the inner
SE rim of Herodotus?) i.e. generally SE of the Cobra's Head.
Blue colour is usually present on the rim of Aristarchus and
to the north - but I don't recall seeing such strong blue
colouration in this region before? No other craters exhibit
this blue colour. As the colour is present in two images,
taken with different cameras it looks genuine. Two other
colour images, at lower resolution, were taken from Oro Verde,
by W.Elias, at 23:06 and 23:18, but neither of these exhibit
this blue colour - but that maybe a resolution issue? ALPO/BAA
weight=3.0
On 1995 October 6 at UT 21:30 R. Lena (Rome, Italy - a UAI observer,
11.4cm reflector) saw 4 or 5 flashes from Herodotus crater. Light
intensities (mag?) ranged from 9 to 8 and they were brighter through a
red filter. There is no 2006 Cameron catalog entry for this observation
- it has come from the UAI web site. The ALPO/BAA weight=3.

On 1985 May 02 at UT 20:20-20:38 J.D. Cook (Frimley, UK) noted at 20:20
found the south rim (and just outside) to be blurred in appearence and
there was also a hazy shadow inside the crater. M.C. Cook found a
"break in clarity in break on S wall". Miles (UK) also found the south
wall blurred in appearance and Foley (Kent, UK) noted that the area was
featureless and the 2 craters positions at 1 o'clock high up on the
inner wall were obscured", although just north of these was sharp
detail. Foley also recorded that the shadow on the east wall was
opaque"and that thye inside of Aristarchus was slate/blue in colour and
dull, however by 20:28 the crater had brightened by 0.4 steps on
Foley's CED device and the missing craterlets were visible again. Jean
(Canada, 4" refractor) observed a rose colour intermittently (UT 1948-
20:58) - however Cameron suspects that this is chromatic aberation.

Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55
image very unsteady. All seems normal in other crtaters with
the exception of Arcimedes. Much of the rim seems indistinct
apart from a 1/4 length of the west rim. Strongly suspected
that this was due to a combination of seeing and illumination.
UT 20:02-20:06 - checked the area with a lower magnification
10" Astrographic Refractor - the crater seems more normal, so
suggesting that the theory was correct. 20:36-20:41 returned
to the 30" reflector, and the crater appeared similar to the
start of the session. This is almost certainly not a TLP, but
it would be helpful to have some images or sketches to check
this theory out. Weight=1.

On 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW,
Australia, 8" reflector, x100, x160, S=III) observed a bright star-like
point on the western (IAU) edge of Mare Tranquilitatis (x100) that
appeared unlike any other crater and a check of the location revealed
no suitably bright crater in that region (from a map?). Changed to a
higher power (x160) and it was still there, but not as conspicuous.
Observer thinks that this may have been due to the Moon's low altitiude
(16 deg) and the seeing. At 18:35 he compared it to the brilliant
crater Proclus and found the star-like point to be 75% of the
brightness of Proclus. Ken Wallace (Australia) had been taking photos
and observed the object at 17:37.5UT. The object gradually faded over
the next 15 minutes and by 18:52UT could only be seen in averted vision

On 1978 Sep 16 at UT19:30 R. McKin (Colchester, Essex, UK, 216mm
reflector and binoculars) observed that Aristarchus, in the lighter
region, during the lunar eclipse, was duller than usual but no less
conspicuous than expected. The Cameron 2006 catalog ID=38 and weight=5.

On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK,
seeing=IV-V, transparency=good, spurious colour seen) found 2
bright pathces on the east rim on alternate sides of a bright region.
The band from the central 16km wide region was dark on the east side.
Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be
not as bright as normal, apart from the band that Mobberley found (1
hour later). The dark regions were a murky green colour (bright through
green, blue and yellow filters and dark through red and orange
filters). Cook (Frimley, UK, transparency=excellent, CCD camera used)
found a bright "bulge"on the eastern side. Apparently data suggests
that the band was brighter in red than in near IR light. Cook's
calibrated brightness measurements suggest that there was no change in
brightness over the crater with time. Two other bright points were
seen: one at the Cobra's Head and another half way between the east rim
of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87
(near IR) and combined Wratten 29 and Wratten 87 were used. In the red
Wratten 29 filter the brightness falls at22:20 at Shroters valley and
then rises in the bright ray. They return to normal at 22:30UT. There
was however a lot of measurement noise from the brightness readings of
points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The

On 2000 Jan 21 UT04:40 G. Emersen (Golden, CO, USA, 30cm focal length
lens with Wratten 25 ref filter) took 43 CCD images of the eclipse of
the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively
bright spot appeared in the southern part of Mare Fecunditatis. The
spot looks sharper than the rest of the Moon and so might be a cosmic
ray? CCD images taken from Washington D.C. by A.C. Cook at this time,
do not show this spot, however exposures were at intervals of 0.25 sec
and so might have missed this spot if it happened during image readout.
The ALPO/BAA weight=1.
On 1953 Jan 29/30 UT 23:00?, 01:00? Dubois (Floirae, France) observed

On 1848 at UT 21:00 Rankin and Chevallier (France?): Luminous pts. seen
during an eclipse. Cameron ays that year 1847 given by Middlehurst must
be wrong as age is 2.7 days for this date in 1847 and could not be 18-
19 as in Middlehurst because eclipse is on the 19th at 21h (mid) in
1948. aux. data here are for 1848. At 21:12 Forster (England) and
Bruges (France) observed rapid changes in red colour. The Cameron 1978

On 1895 Sep 07 an unknown observer (Lewis Swift?) observed a pale blue
segment on the upper limb - this was apparently confirmed by Faulkes
(Mem. BAA, 1895). Cameron says that this is probably 1895 Sep 08 at UT
06:00 as Sep 07 is local time. She also infers that "upper limb" is the
