On 1969 Mar 27 at UT 18:42-18:47 Ringsdore (England, 15"
reflector, x350), Moseley (Armagh, Northern Ireland) and P.
Moore (Selsey, UK) observed nothing unusual in Alphonsus at
18:40UT, but at 18:45UT Ringsdore saw a blurring. At 18:43UT
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
catalog ID=1118 and weight=5. The ALPO/BAA weight=4.
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 &
hard to define. Rest was usual sharp definition. Mistiness cleared at
1930. Cleaned his eyepiece & prism but it persisted." NASA catalog
weight=3 (average). NASA catalog ID #402.
Gassendi 1967 Oct 13 UTC 19:17-20:00 Observers: Henshaw (Mansfield, UK,
8.5" reflector x112) and Corralitos Observator (Organ Pass, NM, USA,
24" reflector) "Phenomenon (brightening ?) nr. NW (ast. ?) lasting for

On 1882 May 27 ay UT 20:00 an unknown observer (10" reflector) saw a
bright luminous ray near west (astronomical?) wall on floor of Plato.
Cameron suggests sunlight between peaks?. The Cameron 1978 catalog ID=
233 and weight=0. The ALPO/BAA weight=1.
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 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=
0. 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

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.

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,

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.

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 1975 Nov 18/19 at UT 23:15-0005 LeCroy Jr and Sr (Springfield, VA,
4.5" reflector, S=7) observed that Menelaus was one of four glowing
spots on the Moon during a lunar eclipse (including Aristarchus). At
23:50UT 3 of these patches emerged from the dark and appeared as bright
spots compared to other craters "Älbedo=10+". At 23:55UT a ray appeared
out of the north east rim of menelaus (Normal?). It appeared just
before the artea emerged and increased in brightness. At 23:58UT it
decreased and continued to do so. The north east edge of Menelaus
appeared very dark at the point that the ray was extending from SW edge
(a ridge there) and apperared to obscure features along its path
(Albedo=9). The Albedos of Manilius and Delambre were 8.5 at 00:05UT.
At 00:05UT the rays were still apparent but seemed to have returned to

Other observers noted this effect.
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

Messier A 1951 Aug 20 UT 01:48-03:00 Observed by P.Moore
(England, 8.5" reflector, x350). Bright cloud like circular
patch seen on S wall of Messier A. It was the brightest object
in the vicinity. Observations ceased due to the Moon setting
behind a tree. W.Haas thinks that this effect is not unusual at
similar colongitudes. Moore checked again under similar
illumination and still considers the Aug 20 appearance abnormal.
NASA weight=4. NASA catalog ID #545. ALPO/BAA weight=2.

reflector, x75 and photography used, seeing 4/10 and the Moon's
altitude was 45deg) photographed Romer crater and recorded two adjacent
bright cigar shaped objects - these were the same size as an
observation made in 1987. Darling believes that these are ridges.
Cameron comments that in LO-IV 192-3,2 a ridge is revealed on the
inside wall that matches the description. Cameron 2006 catalog ID=66
and weight=2. ALPO/BAA weight=1.
On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"?
reflector, seeing III) found that Aristarchus was very bright
and slightly blue. Cameron comments that Moore's eyesight is not
very blue sensitive. The Cameron 2006 catalog ID=175 and weight=
4. The ALPO/BAA weight=2.
On 1982 Jul 09 at UT01:05-01:25 P. Moore (Selsey, UK, 12.5" reflector,

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.
Macrobius 1898 Dec 31 UTC 20:00 Observed by Goodacre (Crouch End,
England, 12" reflector) "Interior nearly filled with shadow at sunset.

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.

On 1991 Dec 28 at UT 02:10 P. Moore (Selsey, UK) could see no detail on
the floor of Plato crater. This report needs to be read in context with
the comments by Cameron for A.C. Cook's observation of the floor of
Plato on 1992 Jan 18 - Cameron 2006 catalog ID=438.
On 1916 Jan 27 at 22:00? Markov (Russia) noticed that a light sector
was visible at the bottom of Plato, in shadow, and contained 3 bright
spots, reminiscent of phfescent bodies. The Cmaeron 1978 catalog ID=362
and weight=3. The ALPO/BAA weight=3.
On 1983 Jan 08 at UT01:00? P. Madej (Huddersfield, UK) noticed some
colour on Aristarchus. The Cameron 2006 catalog ID=196 and the weight=

Theophilus 1955 Jun 25 UTC 20:30 Observed by Firsoff (Somerset, UK,
6.5" reflector, x240) "Blue mist. Both c.p. & ENE (IAU?) ridge appear
misty, slightly blueish & milky -- renders effect perfectly. Absent
next nite". NASA catalog weight= 4 (high). NASA catalog ID #596.
On 1983 Jan 19 at UT 18:00-19:00 G. Amery (Reading, UK) discovered that
Aristarchus could not be seen in Earthshine, this was odd because less
prominent features could be seen. Other observers (Moore and Foley)
confirmed the very low brightness of the crater. The Cameron 2006
catalog ID=197 and the weight=2. The ALPO/BAA weight=2.
On 1983 Jan 19 at UT 18:00-19:00 G.W. Amery (Reading, UK) found that
Messier was difficult to define. The Cameron 2006 catalog ID=197 and
the weight=2. The ALPO/BAA weight=1.
1968 Apr 04 UT 18:45-19:20 Observed by Darnella (Copenhagen,
Denmark, 6" refractor, x183) "Small area just E(ast.) of
Menelaus was seen with a reddish color which gradually faded.
Area was as large as Menelaus & had just come into sunlight. The
dome just W.(IAU) of Menelaus?)." NASA catalog weight=3. NASA
catalog ID #1065. ALPO/BAA weight=3.
On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP
coordinator, Patrick Moore, to report a possible colour anomaly in
Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing
unusual. However by this time North was reporting that, the colour was
fading. Two other BAA members were alerted, but were clouded out. The
ALPO/BAA weight=3.
Webb (England, using a fluid achromat) saw brilliant minute spots and
streaks in Mare Crisium dotting its surface. This was seen near first
quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall
had all seen it this way at times. Cameron 1978 catalog iD=111 and
weight=3. ALPO/BAA weight=2.
Proclus 1972 Jan 23 UT 15:20-16:50 observed by Stolzen (51.17N, 9.25E,
50mm refractor, T=2, S=2) "Pure bright white point within crater" -
Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61
On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia)
noted that Mons Piton was too bright near the terminator and was
surrounded by shadow. A sketch was made. The mountain appeared
segmented with one thin shadow line. The mountain looked like a
Mexican Sombrero hat. This appearance is normal. What was
abnormal was that Piton was brighter than Proclus, and only
slightly fainter than Censorinus. The CED brightness
measurements were normal Piton=3.6, Proclus=3.5 and Censorinus=
3.7. Please check to see whether this is still the case. The

weight=1.
Ptolemaeus 2020 Feb 01 UT 19:40-19:50 P. Sheperdson (York, UK,
102mm Mak - BAA) saw an "ashen" sliver of bright light across
the floor. Images taken. This maybe normal appearance - though
observer re-observed in May and found the effect different in
that there was no "ashen" like effect. Visual sketches and
time lapse image sequences welcome. If doing visual work - try
using a polaroid filter and rotate it to see if that makes any
difference. For imaging work, please over-expose slightly to
bring out detail on the floor; you could also try colour
imaging of the floor as an interesting experiment - though for
comparison purposes image other terminator features exhibiting
shadow spires. ALPO/BAA weight=1.

the Cassini area. The ALPO/BAA weight=2.
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
a Society for Popular Astronomy member and they described "a
homogeneous grey veil over the 20 km floor of the crater". The
Cameron 2006 catalog ID=255 and the weight=2. ALPO/BAA weight=2.
On 1982 Jun 30 at UT 02:05-02:15 Marco Petek (Porto Alegre,

On 1931 Mar 27 R.Barker (observing from Cheshunt, UK, 12.5" reflector)
found that the central mountain in the brilliant ray crater Tycho was a
curious shade of grey. This was despite the interior of Tycho being
fully in shadow. Cameron 1978 catalog ID=400 and weight=3. ALPO/BAA
weight=3.
Tycho 2003 May 10 UTC 03:15 Observer Robert Spellman (Los Angeles, USA)
- "CCD video of spur-like features coming off N & S edges of central
