On 1982 Dec 22 at UT 19:20-20:10 J-H Robinson (Teighmouth, Devon, UK,
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
ALPO/BAA weight=3.

On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3"
refractor, x90, seeing conditions: "at,. boiling") noted a coloured
area on the west wall of Copernicus that was unusual in appearance -
however other craters along the terminator had a similar effect. There
was also a "dazzling bright spot on the E. rim and he witnessed 6
flashes from the lighted part of Copernicus over a very short time
interval. Cameron comments that the colour may well have been dur to
chromatic aberation because a refractor was used. The Cameron 2006
catalog ID=408 and the weight=0. The ALPO/BAA weight=1.
On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3"
reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc.
bright interior uniform gray". The Cameron 2006 catalog report is
slight unclear as the description for thnis 1990 Aug 30 TLP also
includes Copernicus and Censorinus in the list of TLP craters. So one
description which might refere to Copernicus, could possibly have been
meant for Proclus, namely: "Dazling bright spot on E rim. Rotated
eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog
ID=408 and weight=0. The ALPO/BAA weight=1.
Copernicus 1932 Mar 16 UTC 18:45-19:30 Observed by Barker (Cheshunt,
England, 12.5" reflector, x310) "Term. from Cop. to lat.20S was misty &

On 1987 Oct 03 at UT 01:0?0-02:00 R. Manske (Brooklyn, WI, USA, 8"
reflector, x226) observed sunlight glinting of the walls in spectacular
display of colours. White (even gold) was seen at the centre, and blue
on the top most part of the rim. The white (or gold) band was thin in
comparison to other bands. The observer suspects that this effect was
terrestrial atmosphere related. Cameron 2006 catalog ID=307 and weight=

On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5"
reflector, x159) observed an "anomalous black bar across Aris. Nearly
digonal to terminator." The nearby crater Prinz had curious shadow
patterns, perhaps related to the rising sun projecting shadows from the
eastern rim and "reflected down"? "At 0224 W wall had a break in it & a
diffuse glow where it should not be. Manske thinks it was Earthshine
effect. At 0305 Weier saw Manske's bar - with diffused light and
flicker like an aurora - like a gas with electric charge. At 0325 saw a
strange glow in Aris. but may be due to atm. though thought it to be a
LTP. Darling had never seen such effects before (flickering implies a
medium in it)." The Cameron 2006 catalog ID=387 and the weight=3. The

On 1980 Jul 23 at UT22:00 G.W. Amery (Reading, UK, 8" reflector, x144
and x207, seeing=III-V and transparency=fair) found that the interior
shadow was a light grey. BAA TLP coordinator (Foley) suggests that this
was light reflecting from the illuminated walls? Cameron 2006 catalog

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,
York, UK, 30cm reflector, x220 and x350, seeing 3-4/5, and transparency
5/5) - observed from 22:00-23:25UT no colour seen, nor obsecuration,
all filters negative, despite seeing a lot of fine setail inside this
crater.
Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon,
England) - observer noted that the east outside wall was bright in red
and normal in blue. Note that the Moon was 30 deg above the horizon at
the time of the observation. The crater returned to normal at 20:58.
Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D.
Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at
times) noticed a possible obscuration over the southern part of
Gassendi. He had been observing earlier at 18:40-19:30 but had not
detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot
outside the east wall is again bright in red., though by 22:25 it had
faded and was gone by 22:28UT. The Cameron 1978 catalog further
quotes: "Vivid red spots & general red color seen around rim by 2 obs.
At 2209h blood red small area was seen. 1 h later the most westerly

On 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6"
reflector) took some photos (albeit out of focus) that showed a bright
spot on the west rim. Cameron comments that this spot was sharp
compared to the rest of the photograph, so was probably a photographic
artifact. The effect was not seen in the finder scope. The Cameron 2006
catalog ID=103 and weight=2. The ALPO/BAA weight=1.
On 1989 Sep 12 at UT00:58-02:25 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x159, S=7/10) observed similar light conditions to 1989 Jul
15. At 02:00 he observed pink on the south west wall of Aristarchus
crater. At 01:24UT the Aristarchus ray was yellowish, however the
entire Moon had a grey-yellow tinge of colour. Chromatic aberation was
observed at 01:56UT. By comparison Gassendi was checked and had no
colour. At 02:10 the crater wall of Aristarchus was unusual and was
quite different in appearance to rims of other craters. The cameron

On 1980 Jul 24 at UT22:10-22:55 P. Moore (Selsey, UK, 15" reflector,
x360 and x400) found an area just south east of the central peak (and
upto the wall) to be quite dark in blue light, but normal brightness in
red light or in white light. All other features were normal colour-
wise. At 22:55UT Tycho was normal again. Cameron 2006 catalog ID=103

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.
Cobra Head 1966 May 02 UT 20:05 Observed by Sartory (England, 8.5"

Aristarchus. 2024 Mar 23 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
Plato 1967 Apr 24 UT 02:50 K.Simmons (Jacksonville, FL, USA, 10"

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
at x100. By 18:57UT it was gone. The Cameron 2006 catalog ID=38 and
weight=5. The ALPO/BAA weight=2.
On 1942 Aug 26 at UT 04:00 Haas (New Mexico?, USA, 12"
reflector?, very clear sky and good seeing) observed (during an
lunar eclipse) found an unmistakable lightening of a dark albedo
area in Atlas. This area returned to normal darkness during the
4 houres after Atlas re-entered sunlight. Cameron says that the
mid eclipse was at 04:00. The Cameron 198 catalog ID=489 and
weight=4. The ALPO/BAA weight=2.
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.
The ALPO/BAA weight=1.
On 1964 May 26 UT 04:10-04:35 Bartlett (Baltimore, MD, USA, S=5, T=5).
observed that Aristarchus had a strong blue-violet glow on the east
wall and EWBS, with a strong violet tinge on the nimbus. Crater was
hazy, could not focus it in red, green or blue light. The Cameron 1978
catalog ID= and weight=4. The ALPO/BAA weight=2.
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
ALPO/BAA weight=3.
On 2000 Jun 16 UT 20:37 C. Brook (Plymouth, UK, 60mm
refractor, x117 & x40, seeing good, transparency excellent)
observed abright spot on the north rim of Mare Crisium (57E,
25N). It was comparable to the illuminated rim of Proclus in
brightness. No colour seen. The spot was not visible the next
night. The ALPO/BAA weight=1.
On 1953 Jan 29/30 UT 23:00?, 01:00? Dubois (Floirae, France) observed
excess luminescence, in Mare Fecunditatis, between 420nm and 470nm
(maximum at 435nm) and between 480nm and 520nm (maximum near 505nm).
20-60% during eclipse at 50' from the centre of the umbra, during a

ALPO/BAA weight=4.
On 1953 Jan 29-30 UT 23:05-01:40 G. Brown (UK?) observed a white patch
of light of low brightness was seen to move around the north polar
area. Coloured bands were also seen on the Moon.
On 1877 Feb 27 at UT19:19 Prof. Dorna (Turin, Italy) observed a
flickering light on the lunar surface during a lunar eclipse. The

On 1915 Mar 22 at UT 11:30-12:30 Jackson (France?) observed Aristarchus
during a total lunar eclipse: "Dur. totality there remained vis. to the
NW a red luminous pt. not much larger than Mars & of the same color".

On 1895 Mar 10 L. Swift et. al (Lowell Observatory, Flagstaff, AZ, USA)
and Elger et al. (England), observed during a total lunar eclipse that
Aristarchus was glowing with brilliance never seen before. This
attracted everyones attantion. It extended its radiance to adjecent
craters (e.g. Herodotus) all throughout totality. At the subsequent
eclipse in September 1895 it was seen to be inconspicuous. the Cameron
1978 catalog ID=283 and the weight=5. The ALPO/BAA weight=4.
On 1891 May 23 at 18:36-19:15 UT, Jackson of Sheffield, England, using
a 6" refractor, saw "1/2 hour before the end of a totl eclipse, a
region of the crater and just north of it, become conspicuous and
increased in brightness from then on" Cameron thinks this is just the
edge of the shadow and possibly normal. Cameron 1978 catalog ID=268 and
weight=0. ALPO/BAA weight=1.
In 1954 Jul 16 at UT 01:12 Chernov (Russia, 2" refractor, x33) observed
the following for Aristarchus: "Activity noted in it * in extension of
Moon's shadow on sky for 12 min during .17phase of ecl.(source gave
date as June 16, but ecl was July 16)". The Cameron 1978 catalog ID=566

On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a
6" reflector, Seing = 6/10) noticed blue on the north east corner of
Aristarchus and an orange glow on the south east wall. They detected no
movement or change in brightness. The observer used both eyes, to make
sure it was not an eye defect, and three filters: red Wratten 25, blue
Wratten 82 and Violet Wratten 47. Porter found that the colours faded
for a duration of 5 minutes and then returned. Their right eye gave a
good view and using their left eye they suspected that it was 0.5 steps
brighter than the remainder of the crater. The suspected colour
remained visible, even under moments of good seeing conditions. The
colour eventually faded over time and was eventually gone. Porter
reportd seein gcolour here on the following night. Apparently other
bright spots showed no colour. Fitton suggests that the filters used
confirm that the south east wass was definitely red in colour. The

On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300)
noticed a lack of detail in the Cape Agarum area - he would normally
have expected to have seen some craterlets. However he would not rate
this observation much because the seeing was only III and he does not
think that it was an obscuration. However just in case he wanted to
record this report in the archives. ALPO/BAA weight=1.

On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9
refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP
in Macrobius. His report is as follows: "Blinked Macrobius with Wratten
Filters Blue 38A and Red 29. Macrobius became almost invisible through
the Blue 38A and essentially the same as in white light through the Red
29. The interior of the crater was completely in shadow. The only part
of the east wall that was visible was an apparent high point still in
the sun and seen as a bright point of light. This faded into darkness
before 13:56UT. No sign of any illumination of the east wall crater
interior or the interior of the west wall was seen during the
observation period. The outer west wall was a rough looking,
complicated mix of deep shadow and illuminated sunlit terrain." The
observer concluded that there was not a TLP - although he did get a
filter reaction, this may have been due to the different densities of
the filters? ALPO/BAA weight=2.
On 1989 Jan 26 at UT 03:45 De Groof (Belgium) noted a white few second

Aristarchus 1957 Oct 13 UT 07:00?$ W.Haas, according to the 1978
NASA Catalog is supposed to have seen a bright spot of light --
"explosion" in this crater. Confirmation of activity
in Aristarchus - Three independent observations within 4 hours.
Cameron 1978 catalog weight=5 and TLP ID No.=676. Private
comunication with Haas shows that he recorded nothing unusual
on the 12th or 13th. Therefore an ALPO/BAA weight of 1 has
been given until this matter is cleared up.
Fracastorius 2022 Apr 21 UT 01:35-02:12 A. Amorim (Brazil -
90mm f/10 refractor, 25 & 10mm eyepieces ) observed visually a
little bright spot near the centre of the otherwise completely
shadow filled crater. The bright spot was surrounded by a coma
effect. Clouds intervened but by 02:12 the spot was no longer
visible, just a thin patch of light close to the crater's
centre. Observations started when the Moon's altitude was 15
deg and ended when it was 23 deg above the horizon. ALPO/BAA
weight=1.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3"
refractor) observed that the south floor of Aristarchus was wellow -
"almost gold, spilled over S wall on ray toward Herodotus". Cameron
comments that Bartlett often reported a yellow floor but not a spill of
the colour over to the external ray. Cameron also comments that
Louderback's refractor would refract more in blue light than in yellow,
therefore she did not think that it was due to chromatic aberation. The
Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=2.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3"
refractor) found that all of Mons Piton was "unusually dark". Points D,
C (E and S resp), usually brightest points, but this time were not
bright. "Whole mt was as dark as W wall usually is at this time. In
violet filter Piton disappeared completely, but was a little brighter
in red filter and points D & G showed. Color not seen by eye. No albedo
measured. Suggests red event." Cameron rules out chromatic aberation
from Louderback's refractor. The Cameron 2006 catalog ID=431 and the
weight=3. The ALPO/BAA weight=1.
Plato 1975 Jun 28/29 UT 23:00-01:20. Foley (Wilmington, UK, 12"
reflector, seeing, III, good clarity transparency). At 23:00,
00:30, and 01:15 blue was seen on the inner wall:floor southern
boundary, and red on the corresponding northern floor:wall
boundary. However by 01:20, blue was now on the S-NW floor:wall
boundary, and red on the NE-SE floor:wall boundary. Atmospheric
spectral dispersion existed in many regions, but did not change
like the colours in Plato. Similar appearance craters such as
Grimaldi, Schickard, and Riccioli, were checked for a similar
change in colour, but no change was noticed in these. ALPO/BAA

conditions, saw an unusually bright glow covering the dark part, nearly
uniform. Thought it was electric because it was too bright for
earthshine. It apparently obscured features. Cameron's 1978 TLP catalog
ID=243 and weight=1. ALPO/BAA weight=2.
