refractor, x30-x111, S=5/10, T=5.5) observed (UT01:22-02:25) an orange
flare and some brighenings in the crater Gassendi. With the naked eye
he saw a glowing spot on the Earthshine side of the Moon. When he
turned his telescope onto this he found out that this was Gassendi
crater. By comparison, Aristarchus was just a small point. Herzog
(Racine, WI, USA, 2.5" refractor, x28, S=G and T=6-7) confirmed Spain's
observation UT 01:51-02:37?. Darling (Sun Praire, WI, USA, 3"

In 1949 May 31 UT02:37 LT Johnson observed a flash near the W
limb of the Moon at the same latitude as Riccioli. No colour
seen, the magnitude was 9-10, and duration < 0.5 sec. If there
was any motion then it must have been < 24 km. He wasn't looking
at it when it happened, so the motion aspect is uncertain.
Indeed he was not absolutely certain if it was on the limb, or
just inside or outside? The BAA/ALPO weight=1.

orange outburst from the ctater. When E. Watkins had a look, it just
resembled a misty white area i.e. normal. Eyepieces were changed but it
stayed misty white. Hooke was an inexperienced TLP observer at the
time. Watkins did however notice some variation in brightness but put
this down to atmospheric conditions. This is a BAA observation.

bright lunar features showed no such effect. The pink border lay 1 to
2.5 diameters away from Proclus (S=2, T=3.5). At 2:55, UT (S=1-2, S=
3.5) the border was gone; neither its appearance nor disappearance was

On 1991 Apr 22 at UT 01:10-01:22 D. Darling (Sun Praire, WI, USA,
12.5", x99, seeing=7/10) observed that Piazzi-Smyth was
bright in red light but fuzzy in blue light. The Cameron 2006
catalog ID=424 and the weight=3. The ALPO/BAA weight=3.
On 1993 Mar 30 at UT 19:30 an unknown British observer (Reading, UK)
noted that the crater at the end of the Alpine valley looked unusual.
However M. Cook (Frimley, UK) also observed the feature but found
nothing unusual. The Cameron 2006 catalog ID=457 and weight=0. The
ALPO/BAA weight=1.
On 1993 Mar 30 at UT19:35-21:15 J. Knott (England, UK, 8.5" reflector,
x180 and x216, seeing=II and Transparency=good) observed at 19:35 the
central peak of Alphonsus appeared to be extra bright although was
normal later, however the observer suspects that this was a contrast
related and was not confident to send out a TLP alert. The Cameron 2006
catalog ID=458a and 458b and weights=0. The ALPO/BAA weight=1.
Linne 1866 Dec 14 UT 20:00? Observed by Schmidt? (Athens, Greece?, 7"
refractor?) "Seen as a white spot, had been a fine black spot before as
seen by Schmidt. (Also Buckingham in Dec. 1866; also D 16,25th,27th, --

146.
On 1991 Apr 22 at UT 02:03-02:14 D. Darling (Sun Praire, WI, USA,
12.5", x99, seeing 7/10) found, using a red and blue Moonblink
device that Atlas crater gave a blink, the dark spots inside the
crater have a dark nucleus in the blue filter. This effect was
not detected earlier that night. The Cameron 2006 catalog then
says "Atlas normal". The Cameron 2006 catalog ID=424 and the
weight=3. The ALPO/BAA weight=2.
Atlas 1973 Apr 10 UT 18:37-19:49 Observed by Theiss (51N, 9.67E, 75mm
refractor, T=2, S=3) "N. wall of Atlas was yellow-green, several
magnifications tested with the same results" - Hilbrecht and Kuveler,
Earth, Moon & Planets, 30 (1984), p53-61
Torricelli B 2002 Oct 14 UT 02:58-03:43 Observed by Gray (Winnemucca,
NV, USA, 152mm refractor x114, x305, seeing Antoniadi III, transparency
good) "I was out this morning (2:58-3:43 UT, October 14, 2002)
observing Torricelli B. At 3:17 UT the west sunlit wall of the crater
brightened from an intensity (Elger Scale) of 5.0 to 9.0. In actual
terms it went from slightly less bright than the walls of Picard to as
bright as the sunlit west wall of Dionysius. This was observed at 114x
in white light, where all three craters were in the field of view
simultaneously. This event lasted less than a minute and no comparable
brightening in Dionysius or Picard was seen. The wall of Torricelli B
returned to 5.0 in brightness. I continued to observe Torricelli B in
white light until 3:43 UT, but the brightness remained at 5.0. Before
the brightening I tried blinking Torricelli with the following
combinations of filters: Wratten Red 25 and Blue 38A, Red 25 and Blue
80, and Red 25 and Schott BG38 (Blue Green). Nothing showed up more
prominently in any combination except the Red 25-Blue 38A combination,
where Torricelli B became invisible in the Blue, probably because of
the filter density. Both the Blue 80 and Schott BG 38 seemed closer in
density to the Red 25 than the Blue 38A is. I could not see any details
inside Torricelli B during this session, including the bright spot on
the NE rim." The ALPO/BAA weight=3.
On 2009 Apr 02 at UT 21:45-22:05 C. Brook (Plymouth, UK,
5" refractor, x40 and x100, using red and blue gelatine
Edmund Optics filters (rose No. 47 and blue No. 80),
transparency poor due to thick haze. seeing was excellent)
observed that that the rays that crossed Mare Cisrium from
Proclus were brighter in red light than in blue. A similar
effect was also observed, to a lesser extent south of the
Mare. Non-mare Crisium rays from Proclus did not have this effect.
The TLP was not seen at the higher magnification of x100.

On 1978 Nov 08 at UT03:00 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x95, seeing 8/10) saw near Beer and
Timocharis (11W, 30N) a bright flash inside the dark area. It
appeared like a diamond twinkling in sunlight and was somewhat
dazzling to the eyes. Cameron wonders in this was a meteor?
The Cameron 2005 TLP catalog ID=39 and weight=2. This is an
ALPO observation. The ALPO/BAA weight is 3.

On 1980 Oct 17 at UT18:40-19:10 G. Blair (Weir, Renfrewshire,
Scotland, UK, 22cm reflector, seeing II, transparency excellent,
no spurious colour) noticed at 18:40UT that the bright central
peak of Alphonsus was elongated. At 18:41UT, at higher power,
the central peak separated from a bright point of light,
intensity about that of a 6th magnitude star. at 18:43UT a
filter check was made of the suspect point and surrounding
regions - slightly nrighter in red. At 18:50UT intensity of
bright point reduced to equivalent of 4th magnitude star. Noted
that Earthshine was the brightest that he had ever seen it. At
19:03 UT losing the Moon behind a chimney. UT 19:10 brief
appearance, bright point still seen at 4th magnitude. 19:27UT
the Moon disappears again. 20:15UT reappearance of the Moon and
Alphonsus appeared normal. The ALPO/BAA weight=2. This is a BAA

On 1993 Mar 31 at UT19:35-21:15 J. Knott (England, UK, 8.5" reflector,
x180 and x216, seeing=II and Transparency=good) the central peak of
Alphonsus appeared to be bright but the observer was not confident
enough to initiate a TLP alert. The Cameron 2006 catalog ID=458b and
weights=1. The ALPO/BAA weight=0.
Plato 1952 Apr 03 UT 20:45-21:30 Observed by Wilkins and Moore
(Meudon, France, 33" x460) whilst checking up on a 1923 28"
refractor sketch by W.H. Stevenson's, thry failed to detect a
prominent floor craterlet (featured in the 1923 sketch) just
inside the W wall. They suspected an obscuration.
Interestingly the whole floor was was reported to be lacking
in detail many hours later as observed by Cragg in the USA.

On 1989 Jun 12 at UT 21:18-22:25 G. North (Herstmonceaux, UK,
Coude, seeing=V) noted at 21:18UT that Torricelli B was
"barely visible"- possibly this was seeing related. M. Cook
(Frimley, UK, 8" reflector, seeing=IV) found Toricelli B to be
ëxtremely dull - impossible to judge shadows on floor in
contrast to Cens." Holmes (Rockdale, England, UK, 8"
reflector, seeing=II-III) at UT21:30 also found Toricelli B
difficult to find at magnifications less than 200x. Cameron
comments that "Dulling is common on it at high Sun but
illumination doesn't seem to be the cause or related". The

On 2009 Apr 04 at UT 20:30-20:45 C. Brook (Plymouth, UK) observed a
slight pinkish mottling on the floor of Plato. The effect was no longer
visible after 20:45UT. A telephone alert was put out to M. Cook and G.
North. The former saw no colour, but this was after the event finished.
The latter observer reported cloudy conditions. A.Cook was probably
observing at the same time as C. Brook, via a couple of remotely
controlled telescopes in Aberystwyth. The results (time lapse imagery
through narrow band filters) will be examined at a later date.
Plato 1972 Mar 24/25 UT 20:38-00:00 Observed by M.Burton (UK,
13.5" reflector, seeing IV-V, Transparency Fair, x180) UT20:38-
20:45 floor was darker in a red filter than in a blue. UT20:47-
20:56 JS Burgess (seeing 2/5, x200, with and without filters)
found everything normal (with and without filters). UT20:00-
20:07 and 21:30-21:35 A.J. Beddoes found everything normal (with
and without filters). However at 23:10 L.Fitton suspected that
the E (IAU?) floor of Plato had a red-brown cast, but could not
be quite sure. UT23:54-00:00 M.Burton, detected the floor was
darker in red than in blue light. Burton did not detect any
colour without the use of filters on either of the two occasions
that he detecetd a blink. In view of the fact that two observers
did not detect anything, albeit not concurrently with the TLP
reports, this TLP is being given an ALPO/BAA weight of 1.
On 1882 Feb 27 at UT 18:30-19:30 an unknown observer reported an
unusual shadow in Eudoxus. Apparently the shadow was seen to be normal
on 1882 Feb 25 at UT 20:30-20:45. The Cameron 1978 catalog ID=228 and
weight=3. Reference: Sirius Vol 15, 167, 1882. The ALPO/BAA weight=2.
Eimmart 1913 Apr 14 UT 01:00 Observed by Pickering (Mandeville,
Jamaica, 6.5" reflector) "By this date crater was clear & at an albedo
~5?. Drawings compare Jan. 16 & Aug.9, 1913." NASA catalog weight=3
(average). NASA catalog ID #344.
On 2009 Apr 04 at UT 21:40 M.C Cook (Mundesley, UK) after receiving a
telephone alert call, examined Plato crater. Although she did not
report C. Brook's slight mottled pink on the floor of Plato, she did
report through that the floor patches looked darker than normal,
especially in blue light and in red they were not visible at all. In
white light they were darker than normal. A.C. Cook was probably
observing at the same time via a couple of remotely controlled
telescopes in Aberystwyth. The results (time lapse imagery
through narrow band filters) will be examined at a later date.
Note that this observation was made after C. Brook said that he could
no longer see his TLP. Therefore this constitutes a different TLP
as there had been a gap of 1 hour since the last TLP report.
Agrippa 1966 Aug 26 UTC 01:52-02:24 Observer: Bartlett

On 1974 Mar 3 at UT 19:06-20:20 J-H Robinson (Teighmouth, Devon,
UK, 10" refractor, x200, seeing=poor) got a Moon Blink reaction
on the South east wall of Plato, adjacent to the rim shadow and
alerted the BAA TLP network. Ford reported a negtive result at
19:35UT, although Robinson was still getting a blink reaction at
19:40UT, albeit fainter, red at times. Findlay at 19:43-19:52
and 20:00-20:05 saw nothing unusual. Robinson at 19:56UT no
longer saw a blink, but it returned at 20:05UT. Light in bothred
and blue filters. Not steady, but coming and going and gone at
20:09UT. Moore at 19:59-21:00, kennedy at 20:12-20:30, Taylor at
20:48-21:03 and Fitton at 20:05UT all got negative results. The
latter time coincides with Robinson's second blink reaction.

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

Aristarchus and vicinity 1975 Feb 28 UT 03:20-03:45 Observers LeCroy
Jr & Sr (Springfield, VA, USA). NASA catalog states: "Orange flash in

USA, 8" reflector x300) "Landslip at west would not focus. (Ricker not
certain it was a real LTP)." NASA catalog weight=2 (low). NASA catalog
ID 973.
In 1950 Jul 02 UT07:22 Bartlett (Baltimore, MD, USA, 3.5"
reflector) saw no dark bands on the inside of Aristarchus,
despite detail being seen elsewhere. He would normally have
expected to have seen bands at this colongitude, based upon past
observations. The ALPO/BAA weight=2.
Aristarchus 1964 Oct 23 UTC 02:35-02:45 Observed by Bartlett
(Baltimore, MD, USA, 3" refractor, 133 & 200x, S=3-5, T=4) "South floor
region granulated, 6 deg bright with very faint trace of pale yellow
color; rest of crater 8 deg bright." NASA catalog weight=4 (good), NASA
catalog ID #859.
On 2002 Sep 23 at UT22:45-23:56 C. Brook (Plymouth, UK) noticed that
the bands inside Aristarchus varied (UT22:45-22:56) in definition
whilst the rim of Herodotus and the rays of Kepler and Copernicus
remained sharp. These bouts of variation were 1-2min in duration. At
23:56UT when he checked again the periodic blurrings of the bands were
still present. The observer suspected atmospheric effects. M.Cook
(Frimley, UK) observed 22:00-22:30 and could see only 2 bands on the
west wall - but this may have been because of poor transparancy. The
ALPO/BAA weight=1.
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.
In 1962 Sep 16 at UT08:05 Spirad (Victoria, B.C., Canada, 48"

Proclus 2001 Nov 04 UTC 07:00-07:43 "Robin Gray of Winneucca, Nevada,
U.S.A. reported a contrast effect and brightening in the crater
Proclus. Using a 15.2 cm refractor he conducted a Moon blink search
with Wratten 25a and 38a blue filters. His report goes as follows:
Moon Blink carried out. In Red 25 Proclus looked nearly the
same as in white light. Through the Blue 38a filter, however, only the
brilliant lit south east wall was clearly visible. The northeast wall
was very dim with this filter. With no filters the NE and SE wall were
brilliantly lit, the SE wall was almost as bright as Aristarchus. A
thread like strip along the NW wall, possibly the rim of the crater,
was also brilliantly illuminated. The interior of the crater was a
featureless stygian black with the exception of a brilliant (intensity

Aristarchus 1964 Aug 28 UT 04:30-04:50 Observed by Bartlett
(Baltimore, MD, USA, 4" reflector x240) "Faint blue-viol.
radiance on EWBS; dark viol. on nimbus. S.floor dull, 6,
granulated, distinct yellow-brown; rest of crater 8 bright.

On 1980 Oct 30 at UT03:19-03:41 P. Madej (Huddersfield, UK, 158mm f/4
reflector, seeing I-II, and transparency very good. Wratten 15 (yellow)
and Wratten 35 (purple) used. No spurious colour seen). At 03:19UT, the
observer noted that Mons Spitzbergen looked sharper at x52. At x72
bright flashes of a bright lunar gray to a light orange colour seen.
BAA Lunar Section TLP team alerted. At 03:32UT a yellow filter used and
the flashes were better seen, one flash approximately 20-30 sec apart.
At 03:31UT Madej used a purple filter and could not see Mons
Spitzbergen but did see the flashes (45-60 sec apart). cameron 2006
catalog TLP ID=118 and weight=3. ALPO/BAA weight=3.
Plato 1980 Oct 30 UT 05:00-0704 Observed by F.C. Butler (SW
London, UK, seeing III, but worsening (but not as bad as IV)
towards the end of the observing period, transparency 100%
clear, 22cm Newtonian reflector, x144, x185). The floor seemed
quite devoid of detail, apart from a vague mottling seen during
the briefest moments of best seeing conditions. At the start of
the observing period he could just glimpse the central craterlet
at x185, but could not be sure. ALPO/BAA weight=1.
Alphonsus 1964 Oct 27 UTC 05:18-06:10 Observed by Hall, Johnson,
Weresulk (Pt. Tobacco, MD, USA, 16" reflector x400, S=5-7). "Red spot.
Pink glow detected with Trident MB & seen visually too." NASA catalog
weight=5. NASA catalog ID #863.
Alphonsus 1958 Dec 03 UTC 11:00? Observed by Alter, Mt Wilson, CA, USA,
60" reflector "Photog. spect. showed floor of crater redder than
neighboring areas outside its walls. (Palm had a rep't for this date --
same area?). NASA catalog weight=4 (high). NASA catalog ID #710.
On 1994 Jan 04 at UT21:00 J. Nibbering (Rosendaal, Netherlands)
obtained a photograph that shows a large crescent of light centred on
Tycho crater, but includes also: Lilius, but not to Clavius. Cameron
suspects strongly that it was caused by camera lens flare. The Cameron
2006 catalog ID=471 and the weight=5. The ALPO/BAA weight=1.
On 1981 Oct 21 at UT13:40-13:45 D. Louderback (South Bend, WA, USA,
10" reflector) observed a cloud on the north east quadrant of
Aristarchus crater, and also covered the bright spot on the east wall
(Cameron says that the east wall bright spot is Bartlett's "EWBS".
Louderback mentions that this TLP gave Aristarchus a diamond ring
effect. The Cameron 2006 catalog ID=157 and weight=3. The ALPO/BAA
weight=2.
Aristarchus appeared dimmer than normal.
This report has an ALPO/BAA weight of 1.
On 1882 Apr 11 at UT 21:00 Williams (England, 6.5" reflector) observed
Plato at sunset (date Cameron gives is calculated from #229) and saw a
curious phosphorescent glimmer in the crater where he had seen a
luminous milky appearance before. at sunrise. The cameron 1978 catalog
ID=230 and weight=3. The ALPO/BAA weight=3.
On 1978 Jan 02 at UT23:00? A.V. Arkihpov and A.R. Kharkov (USSR)
observed in the terminator region (near Adams?) a flash enclosed by a
fuzzy envelope (180x120 arc seconds in size). The TLP faded away over
30 seconds. Cameron says that this is the first example of many
photographs that registered activity. The Cameron 2006 catalog ID= and
weight=5. The ALPO/BAA weight=2.
On 1963 Nov 10/11 at UT 23:35-00:32 Kopal (Pic du Midi, France, 24"
refractor) observed a TLP in Copernicus. Cameron says that the date
maybe a misprint, should be 11/1/63? - sunset terminator at 25W and
Copernicus in dark. The Cameron 1978 catalog ID=782 and weight=0. The
ALPO/BAA weight=1.
On 1963 Nov 10/11 at UT 23:35-00:32 Kopal (Pic du Midi, France, 24"
refractor) observed a TLP in Kepler. Cameron says that the date maybe a
misprint, should be 11/1/63? - sunset terminator at 25W and Copernicus
in dark. The Cameron 1978 catalog ID=782 and weight=0. The ALPO/BAA
weight=1.
On 1821 July 25 at UT 03:30 Gruithuisen (Munich, Germany) observed,
near Aristarchus, some brilliant flashing spots on the Earthlit side of
the Moon. These disappeared after a short while then re-appeared. The
Cameron 1978 catalog ID=90 and weight=4. The ALPo/BAA weight=3.
On 1963 Nov 11 at 23:30UT Jacobs (Flagstaff, AZ, USA, 24" refractor,
seeing=very good) observed a reddish-orange colour in Aristarchus
crater and a sparkle in some areas. The Cameron 1978 catalog weight=3.
