states: Variable transparency - colourless bright area SE of
Ross D with variable condensation. ALPO/BAA weight=1.
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.
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 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.
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 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 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 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

(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.

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

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 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.
In 1962 Sep 09 at UT 01:42-02:00 Bartlett (Baltimore, MD, USA,
5" reflector, x180, S=5-4, T=3) observed in Agrippa the shadow
of the central peak to be grayish, not much darker than the

On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector,
seeing=III) found the region around the cleft on the souther rim to be
out of focus - however atmospheric conditions were turbulent until
23:18UT. An unsual dark triangular region (long base against rim) was
seen to extend from the inner rim at 12 o'clock onto the floor for 13-
16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK)
found the south east to soth west to be obscured again, but not as
badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the
dark region had 2 white bands on the side and the south west wall was
blurred like it was on the 20th July - this time tough colour was not
present. There were also two light patches on the floor. Mosely
(Coventry, UK) observed the south wall at x120 and found the wall out
of focus at the 11 o'clock location. Through a yellow filter he saw a
"white mistiness: on the top of the southern rim and only the south
east cleft could be seen (no colour). By 22:40-23:00 the effect had
cleared up. No dark triangular patch was seen. When Marshall (Surrey,
UK) observed (22:30-03:00) nothing unsual was seen, though a sketch
provided shows a light patch on the floor located at 11 o'clock. All
observations, made by all observers had some atmospheric turbulence,

Aristarchus 1989 Jul 15 UT 02:00-04:20 Observed by Manske, Weier,
Curtis, Keyes, Yanna, Norman, Knutson, Sullivan, Eichman and Radi (Carl
Fosmark Jr. Memorial Observatory, Madison, WI, USA, SCT C11) "Manske
initially observed a reddish tinge on the SE rim of Aristarchus. The
colour was present in different eyepieces. Two other pinkish tinge
areas were seen on the SE and NE rims. 4 of the observers did not see
colour. Independent confirmation was made by Don Spain (KY) and Smith
in LA. Full details can be found on the following web site:

On 1992 May 13 at UT 20:16-21:29 several observers reported a TLP in
Plato mostly concerning the visibility of floor craterlets, however
observer seeing varied from III-V. North (UK, 18.25" reflector)
reported "Colouration and floor craterlets very prominent. Seeing
Antoniadi V, Transparancy Poor.". Foley (Kent, UK, 12" reflector
seeing=III-IV) found the floor to be bright and in the better moment of
seeing detected floor craterlets. The WNW spot was misty some of the
time. Moore (Selsey, UK, 15" reflector, seeing V) had very poor seing
conditions. J.D. Cook and M.C. Cook (Frimley, UK, 3.6" reflector,
seeing II-III) used a CCD camera at 22:11 UT. The Cameron 2006 catalog

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.

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.

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

On 2017 Sep 02/03 UT 23:55-00:30 A.Anunziato (Parana,
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.

Cavendish 1956 Jan 24 UTC 20:34-20:45 Observed by Houghton and Warner
(England) "Variable flashes seen from W. inner(?) wall of crater, then
a little inside the terminator. Flashes began with a bright glare at
20:34, were very bright for ~3 min, then faded. Flash rate
approximately every 1.5 sec. Other point like peaks did not flash. Also
indications were seen of reflections of flashes from E. (inner?) wall
and the crater's floor was faintly lit by a glare. Ref: Strolling

On 1985 Jun 29 at UT 22:56 M.C. Cook (Frimley, UK, seeing poor)
observed that Torricelli B looked as bright as a mountain to its south
west - no colour was seen. Cameron comments that this was similar to
Marshall's 1985 Jul 1 observation. The cameron 2006 catalog ID=278 and
the weight=3.
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 22:30-00:00 Fisher (Colefax, CA, USA, 8"

reflector, x140 and 2.5" refractor) observed in Promitorium Agarum that
one of his pre-designated points, called "A", through to "C and "D" was
at least 5 brightness points brighter in red than in blue light. The
reverse was true on Sep 25th. Tonight the red seemed to be on a narrow

On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar
telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a
dusky dark gray area just north of Herodotus and just south of the
Cobra Head. The interior shadow on the east of Herodotus by comparison
wad black and distinct. No change was seen when viewed through a
rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA)
was observing at the same time but had better observing conditions and
could see detail in this region, suggesting that it was not a TLP.
There is no Cameron entry for this report. The ALPO/BAA weight=1.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi
III seeing, 12.5" reflector) "Intensely bright craterlet south of central

Aristarchus 1976 Jan 15 UT 19:30-20:50 Observed by P.W. Foley
(Kent, UK, 12" reflector) - Aristarchus was abnormally bright
(Cameron suspects that this is a confirmation an explosion
effect seen earlier by Greenland: "On 1976 Jan 15 at 19:45Ut
Greenland (Crawley, UK, 7x50 binooculars) thought that they
saw an "explosion" on the Moon (in the general region of
Aristarchus) for a fraction of a second, followed by a bright
spot in the same position (not an astronomer). After
discussions with others, decided it was a moment of transition
to greater intensity (better seeing?). Moore thinks it was
atmospheric but says it should be on record. Cmeron's 1978

On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by N. Hazel
(Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max,
with 2x teleconverter, at f9, 1/320 sec, ISO 400 – tripod
mounted, mirror up), A series of images were taken. The 21:06 one
showed a grey column cutting across the central floor of the
crater from the west and then bisecting the eastern rim. All
detail inside is completely invisble. Some (but not all) of the
other images showed a more blurred view of this feature. It's
possible that this was a seeing ripple effect, or just the
natural appearance of shadings on the Moon at this time, however
for now this will be given an ALPO/BAA weight of 1.

On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade
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
visible on these nor variations. Apparently the observer had seen this
type of TLP before but had not reported them. The Cameron 2006 catalog

telescope, x130, seeing=III) managed to see the central craterlet in
Plato and an unnamed one north west of Mons Pico. Cameron comments -
"were this & No. 429 LTP or just good seeing?)." Note it is possible
that she mean LTP 439 in which case it would refer to the previous
nights TLP. The Cameron 2006 catalog ID=439 and the weight=2. The
ALPO/BAA weight=1.
In 1962 Sep 16 at UT08:05 Wildey, Pohn (Mt Wilson, CA, USA, 60"
reflector) Taruntius faded from Vmag-3.21 to 4.04, a 0.82 difference in
magnitude in 2.5 hours - a photometric measurement. The average
magnitude for this age is 4.03, so therefore the crater had brightened
by two times above normal. The Cameron 1978 catalogID=769 and the
weight=5. The ALPO/BAA weight=3.
Mare Crisium 1965 Oct 11 UTC 10:10 Observed by McCord (Mt Wilson, CA,

x260) saw at 01:25UT an unmistakable red-orange glow on the south and
south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected
it easily. At 01:33UT the colour was barely visible. No TLP alert was
issued because the souther edge of Mons Pico also exhibited a hint of
colour, and anyway the seeing conditions were poor. Despite this no
other features revealed colour. The Cameron 2006 catalog ID=446 and the
weight=0. The ALPO/BAA weight=1.
On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector,

Aristarchus 1970 Apr 23 UTC 07:00
Observed by Thomas
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.

On 1981 Jan 09 at UT 00:30-00:45 D. Darling (Sun Praire, WI, USA,
12.5" reflector, seeing=8/10, transparency clear, but Moon low at 7 deg
above the horizon) found that despite Aristarchus being seen to be
bright in Earthshine, it was not as bright as Menelaus and Manilius.
Cameron 2006 catalog ID=121 and weight=1. ALPO/BAA weight=1.
On 1981 Jan 09 at UT 00:30-00:45 D. Darling (Sun Praire, WI, USA,
12.5" reflector, seeing=8/10 and the sky was clear - the Moon was at
7deg altitude though) saw that Manilius outshone Aristarchus - or was
it that Aristarchus was especially faint tonight? Manilius could be
seen even when the illuminated part of the Moon was in the eyepiece.

Heywood of Wheatville, Ohio, USA, using a 2" refractor under fair
seeing conditions, saw a misty light on the dark limb (similar to
Cameron's 1978 catalog TLP 239). The effect had narrowed down on the
30th. Cameron comments : "old moon in new moon's arms?". Cameron 1978
catalog TLP ID=242 and weight=1. ALPO/BAA weight=1.
In 1949 May 02 at UT 03:30-04:00 Barcroft (Madera, CA, USA, 10"
reflector, x96) observed in Aristarchus crater, in Earthshine, a
dull glow -- silvery phosphorescence.This was not visible for 30
min prior. Cameron comments that this is a confirmation of
Wilkins TLP from a few hours earlier? The Cameron 1978 catalog
ID=519 and weight=5. The ALPO/BAA weight=2.
Proclus C region 1985 May 23 UT 17:41 Photographed by Kolovos (observer
from Thessoloniki, Greece, observing site near Bafra Serrain, Greece,
4"refractor, seeing excellent) "Observer took a series of expousres on
a portable scope of the Moon. On one of them a very bright slightly
elliptical spot was seen. Spot was very close to the Proclus C crater.
Upon analysis it was claimed that the spot of light had rotated the
direction of illumination of shadows in adjacent craters - however
subsequent analysis casts doubt on this. Papers on this report
were published in Icarus. Rast and Maley suggested that it was sun
glint off a spinning US ex-military weather satellite that just by
chance came across the field of view of the Moon a few tens of seconds
around the time of the photographed flash. Was this a coincidence or
not? If it were a satellite sun-glint then the satellite would have to
be tumbling incredibly fast in order for the flash to be so sharp in
the photograph - so the satellite explanation is not completely 100%
confirmed." The Cameron 2006 catalog ID=273 and the weight=5. The
ALPO/BAA weight=2.
On 1990 Jun 27 at UT02:17-03:00 D. Darling (Sparta, WI, USA, 3"
refractor, x36) reported that the crater had "Flared up at 0225 as a
point of light then went down" - the effect was fairly brief.
Earthshine was quite clearly seen and all features elsewhere were
normal. The Cameron 2006 catalog ID=405 and the weight=0. The ALPo/BAA
weight=1.
Om 1990 Mar 01 at UT 00:59-02:20 D. Darling (Sun Praire, WI, USA, 3"
refractor, x36) observed that Aristarchus could barely be seen, but at
02:15 UT it brightened by about two times. Note that brightening might
refer to Lambert - it is worded in an ambiguous way in Cameron's
catalog). The Cameron 2006 catalog ID=392 and weight=0. The ALPO/BAA
weight=1.
Om 1990 Mar 01 at UT 00:59-02:20 D. Fryback (Madison, WI, USA, 8"
reflector) observed that Lambert was a star-like point, but later saw
it brighten up (02:15UT) by two times (note that this brightening might
refer to Aristarchus - it is worded in an ambiguous way in Cameron's
catalog). The Cameron 2006 catalog ID=392 and
weight=0. The ALPO/BAA weight=1.
On 1971 Jul 26 at UT 21:40-22:05 daSilva (Paranaiba, Brazil, 13"
refractor, x224, seeing=good and transparency=fair) observed two
brilliant points in Aristarchus - the right one was the more
brilliant of the two. The observer says that this was not a TLP,
but is similar to other reports (Apollo 15 watch). The Cameron
1978 catalog ID=1300 and weight=1. The ALPO/BAA weight=1.
In 1965 Jul 03 at UT 04:25-05:34 Emanuel (West Covina, CA, USA, 4.5"
reflector) observed 4th magnitude star-like flashes and pulsations
coming from Aristarchus. Cameron says this confirmed and that the date
in MBMW is 7/2/65 which is local time = 3rd UT. The Cameron 1978
catalog ID=882 and weight=3. The ALPO/BAA weight=3.
On 1965 Oct 30 at UT 0200 Eastman (Palos Verdes, CA, USA, 12"
reflector) observed a brightening in Aristarchus in ashen light. The
photographs that were taken show it. The phenomenon was seen each
lunation since July. The Cameron 1978 catalog ID=908 and weight=5. The
ALPO/BAA weight=2.

On 1971 Jul 27 at UT 18:30 Miranda (Piaui, Brazil, 4" refractor, Moon
at 70deg altitude) observed Beaumont to have a curious brilliance in
its interior: suspected a change (Apollo 15 watch?). The Cameron 1978
catalog ID=1301 and weight=2. The ALPO/BAA weight=2.
McClure vicinity 1976 Apr 04 UT 19:36-2009 Observed by McKay
(England, 3" refractor, x160), Savill (England, 10x50
binoculars), Moore (Sussex, England, 15" reflector, x360, seeing
II), Buss (England, 6" reflector), Brady (England, 8"
reflector), Ross (England), Foley (Kent, England, 12" reflector)
"Noted a fuzzy, glowing spot at 1936h at 160x. 2 min later, spot
grew larger & flashed up to very bright. Changed power to 106x,
& 80x, still vis. Spot faded 10 m later, then suddenly flashed
up again. 5 m later it faded again & disappeared at 1959h. At
2006h returned to fuzzy, glowing spot then disappeared at 2009h,
never to reappear. Some obs. confirmed, others did not. Photos
afterward don't show anything, nor did blink aftwerward." Moore
though nothing unusual. NASA catalog weight=5. NASA catalog ID #
1431. ALPO/BAA weight=3.
On 2009 Mar 01 at UT 18:50-21:00 G. Smith (East Yorkshire, UK, 127mm
Maksutov Cassegrain telescope with zoom eyepiece and later a Plossl
eyepiece) observed an area between Plato and Sinus Iridum to be glowing
as a bright nebulous patch. It was brighter than anything else in
Eartshine. A change in eyepiece did not affect the appearance of the
nebulous patch. The patch had faded somewhat by 21:00UT. The observers
brother attempted to observe the patch through a 114mm reflector at
20:30UT but the optics were of poor quality and the effect was not
seen. BAA observers were alerted, but only after the event had faded -
they made observations from 22:00-23:46 UT but failed to detect
anything unusual in the region concerned. The ALPO/BAA weight=1.
This may have been a mis-identification with Aristarchus - however
we cannot be 100% sure.
In 1965 Jul 04 at UT 03:53-05:59 Gridley, Welch (West Covina, CA, USA,
4.5" and 8" reflector, seeing=excellent), Albert (CA, 8" reflector,
x375) and Emanuel (8" reflector) observed star-like flashes in
Aristarchus crater. Cameron says this confirmed and that the date
in MBMW is 7/3/65 which is local time = 4th UT also but is in error due
to misreading of handwriting. The Cameron 1978 catalog ID=883 and
weight=3. The ALPO/BAA weight=3.
Proclus 1877 Mar 21 UT 20:00? Observed by Barrett (England?)

Albategnius 1972 Jun 18 UTC 19:20-19:25 Observed by Schnuchel (13.25E,
52.5N, 20x60 binoculars?) "Bright area at the inner N wall, diminution
of brightness well observable" S=4 T=4. Ref: Hilbrecht & Kuveler Moon &
Planets (1984) Vol 30, pp53-61.
Proclus 1972 Jun 18 UTC 20:50-21:15 Observed by Kern (8.75E, 48.25N,
60mm refractor) "Yellow to white bright pattern at the NW wall, visible
only occasionally" S=4, T=3 Ref: Hilbrecht & Kuveler Moon & Planets

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.
Alphonsus 1968 May 05 UT 20:00 Observed by Farrant (Cambridge,
England, 8" reflector, x220, Seeing: Good). "Did not see gray patch SE
(ast. ?) of c.p. Noted W. (ast. ?) dark patch was invis. while S. one
was seen easily, emerging from shadow. On 7th all seen easily, emerging

Daniell 1983 Jun 18 UT 22:06-22:25) P.Madej (Huddersfield, UK,
77mm refractor, x83,x166, seeing II-III, transparency fair).
Noted on the inside W eall a faint red rose like glow (with a
diameter? about it). The red glow varied in brightness with a
period of about 2 minutes. It looked somewhat brighter at x166.
The glow was still visible when the observation ended at 22:15
ALPO/BAA weight=1.
Vallis Alpes 1983 Jun 18 UT 22:01-22:23 P.Madej (Huddersfield, UK,
77mm refractor, x83,x250, seeing II-III, transparency fair).
After studying the whole length of this valley, the observer saw
a change in "albedo" and a small change in colour of the valley
floor near to the Plato end. This colour was not seen in a
yellow Wratten 15 filter but was noted in a purple Wratten 35
filter, and was strong in a red filter. Also the crater
Trouvelot was not seen at x250 with a x2 Barlow.Wratten 25.
ALPO/BAA weight=1.
On 1979 Sep 29 at UT10:00-12:00 S. Turner (Maryborough, Australia)
observed a strong beacon like flash in white light that moved back and
forth in the east wall of Plato (very bright) and Mons Pico. tried
changing eyepiece and the field of view, but this wasn't the cause of
the effect. A check at 11:07UT did not show the effect, but it was back
again by 11:18UT being more pronounced at Mons Pico than the east wall
of Plato. SSW of Mons Pico was also blinking slightly. At 11:32 the
blinking effect was irregular 5-10 sec and this continued until
12:00UT. Cameron 2006 catalog ID=71 and weight=0 but she suggests
atmospheric scintillation as a cause. ALPO/BAA weight=1.

On 1871 Nov 20 at UT 17:30-19:30 H. Pratt (UK) saw one of the most
spectacular TLP obscurations that he had ever seen in Mare Frigoras. He
observed a kind of haze around the north west (NE?) slopes of Plato.
This effect was not seen elsewhere and all objects in Mare Frigoris
were indistinct or veiled. By 18:30 the effect was modified and by
19:30 very little trace was seen. Ref. from Corliss.
Plato 1887 Feb 01 UT 18:00 Observed by Elger (England) "Ill-defined
shadow of peaks of W.border-in contrast to sharpness of mts. outside
it. Never seen before. Such phenomena occur on floor, but never on
