illuminated and a central feature on the floor, faintly seen -
both of these are normal. The crater itself though was much
brighter in a red filter, bright in a wellow filter, but dull
in a blue filter. Possible variation seen whilst using the red
filter, but this may have been due to haze. All other features

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.

La Hire 1922 Nov 28 UT 22:00? Observer Wilkins (England). NASA
catalog states: "Shadow cut thru by white streak (real LTP?.
Pickering's atlas shows same phase & col. & shadow is all

Manilius 1972 May 22 UTC 20:10-20:40 observed by Kern (48deg 45'N, 8deg
45'E, 60mm refractor) "The SW inner wall became brighter at times" -
Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61.
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 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.
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.
On 1983 Aug 19 at UT 07:15-07:30 D. Louderback (South Bend, WA, USA,
3" refractor, x150) found that the direct sunlit side of Mons Piton
mountain (E) was brighter than (his designated) points C and D and this
happened at the same time as some "blurring"at 07:15UT. The darker
side, between C, A and B were not so dark through a red filter as
through a blue filter (this was the opposite of what had been seen
before at a high sun angle). Louderback suspects that there had been a
colour change since he last observed. He also noted that in red light
the whole lunar disk appeared fuzzy and out of focus. Louderback noted
a 1 sec brightness on the east slope and the whole mountain sharp in
blue light. The Moon's altitude was low though. Brightness measurements
were 4 in blue light and >= 4.6 in red light and "so illdefined almost
blended into plain". Cameon commnets that a telescope colour/focussing
issue may have been at work here! The Cameron 2006 catalog ID=226 and
weight=4. The ALPO/BAA weight=1.
Campanus 2014 Jan 11 UT 22:00-22:30 S.Bush (UK, 6" SCT, x180,
seeing average) made a sketch of the Campanus and Mercator
craters. He found that the central peak of Campanus difficult
to resolve and the floors of both craters were devoid of
detail. Mercator was the lighter shade of the two floors.
Earlier at 19:47 UT M.Brown (Huntingdon, UK) imaged this
region and using Registax resolved details on the floors of
both craters, though Mercator clearly was slightly lighter in
floor shade and had less detail on its floor than Campanus.
The most likely explanation was that it was just seeing
effects blocking the visibility of detail - this of course is
less of a problem for a Registax usid on the CCD image.
However just to be sure this observation is being given an
ALPO/BAA TLP weight of 1, to encourage visual observers to
attempt this observation under similar illumination and
seeing.
Parry 1974 April 03 UT 01:10-01:45 Observed by Porter (Narragansett,
Rhode Island, USA, 6" reflector, S=F, T=2) "Darkening of floor &

sketching Gassendi, that at 02:14 the central peak was very
bright in red light, and barely detectable in blue light. By
02:26UT a strong blink was noticed on the NW rim, being very
bright in the red filter. Effect still present at 02:32UT. The
effect was not seen earlier at 01:57UT. The Cameron 2006 catalog

red filter at 02:18UT saw a bright area on the west wall of
Aristarchus crater become 2x brighter than normal then faded
back to normal in < 1 min duration. The spot was 8km centred on
sigma=0.682 and eta=0.397. No events seen at Kepler (Apollo 10

On 1969 May 28 at UT 02:18 Delano (Taunton? MA, USA, 12.5"
reflector, x300) suspected a short duration flare up on the W
wall of Aristarchus at 0.682 and 0.397, but it may have been due
to poor seeing. No events seen at Kepler (Apollo 10 watch). The
Cameron 1978 catalog ID=1149 and weight=4. ALPO/BAA weight=1.
On 1975 Feb 22 at 19:00-22:50 Fitton (Lancashire, UK, 8" reflector,
seeing=II-III-I) saw Aristarchus (at 19:00UT) blue, with no obscuration
visible in white, red or blue filters. This was not a telescopic
effect. "Obs. 4.5h. Says it & next 5 nites obs. were due to high
pressure system W. of obs.". Foley found nothing unsual in Aristarchus
in his observing session, which overlapped Fittons. The 1978 catalog

On 1975 Feb 22 at 20:04-22:50 P.W. Foley (Kent, UK, 12" reflector,
seeing=good) observed Prinz to have a diffuse white obsecuration. There
were pulsations of 30-50sec intervals. Effect ceased at 22:50UT and
indeed was fading earlier from 22:35UT. Photgraphs were taken but
showed nothing unusual and no colour. Aristarchus was also negative.

On 1980 Dec 18 at UT20:46-23:58 A.C. Cook (Frimley, UK, 12" reflector,
40-250x, S=IV and transparency good) found the north west wall to be
brighter in red than in blue light, however the effect faded during
21:29-21:41UT and was gone by 22:40UT. There was however spurious
colour on the north west wall. M. Cook (Frimley, UK) found the central
peak to be both bright and diffuse, and brighter in red than in blue
light during 20:52-20:57UT, however at "22:53-23:58 c.p. very bright &
previous area decreased in size. No detail in white or red, just

On 1992 Mar 16 at UT 00:39-01:14 D. Weier (Sun Praire, WI, USA, 11"
reflector) at 00:39UT noted some soft, diffused, faint ïllumination
within the shadow projected over the Cobra Head area, though it had a
sharp appearance to the edge of the shadow. D. Darling (Sun Praire, WI,
USA, 11" reflector) was taking photographs from UT 00:51 and making
drawings and visual descriptions. The first 3 photographs in the
sequence have the crater as normal. Four other photographs reveal an
abnormality. Seeing conditions were excellent and a great deal of
surface detail was seen inside Aristarchus crater - however the
apeparance of the Cobra's Head was "washed out" and again shadows near
to this were illuminated. The NASA catalog ID=442 and the weight=5. The
ALPO/BAA weight=3.
Herodotus 1950 Jun 27 UTC 02:30 Bartlett (Baltimore, MD, USA) reported

Aristarchus 1983 Aug 03 UT 0305-0400 Observed by R,Moseley
(Coventry, UK, 6" reflector, seeing II, Transparency very good).
At the start of the observation, the NE wall and immediate
exterior was the brightest area visible (this is normal) and
seemed tinged with a faint blue/violet. At 03:45 the impression
of colour was fading in the brightening sky, but by 03:55 the
colour was back again with a faint violet/purple surrounding the
whole formation from E clockwise to N. The observer found it
difficult to decide whether it was really a colour on the Moon,
or an optical illusion. ALPO/BAA weight=1.

On 1978 Jan 12 at 08:21UT (assuming this is not local time) V.A.
Golubev (Ussurian Sam Station, Vladivostock, Russia, x100) saw on the
western edge of the Moon an occultation of the magnitude 6? star
ZC2394. Just prior to the occultation, between the star and the dark
limb could be seen a bridge of light. The ALPO/BAA weight=1.
On 1980 Nov 10 at UT18:05 J-H Robinson (Teighmouth, Devon, UK, Seeing
III, Transparency poor, Filters Wratten 25 (red) and 44A(blue)) found
the area to be bright in red and dull in blue - but suspected that this
might have been a permanent colour blink e.g. natural colour. This does
not have an entry in the 2006 Cameron catalog. ALPO/BAA weight=1.
On 1980 Nov 10 UT 17:55-18:15 J-H Robinson (Teighmouth, Devon, UK)
observed the floor patches in Plato to be easy in red, but not so well
seen in blue. This is a BAA Lunar Section report. ALPO/BAA weight=1.

the previous night". Its diameter is less than 3"
(5-6 km) as judged by comparing with the angular diameter
of Jupiter and also Jupiter's third satellite (the
diameter of the active part of the volcano was at least
twice the angular diameter of Jupiter's Moon). The shape
was an irregular round figure with very sharply defined edges.
It resembled a small piece of burning charcoal, when it is covered
by a thin coat of white ash. The other two volcanos were
much further towards the centre of the Moon and
resembled large faint nebulae that are gradually
much brighter in the middle; but with no well defined luminous
spot within them. These three spots are plainly to be
distinguished from the rest of the marks upon the Moon;
for the reflection of the Sun's rays from Earth is, in its present
situation, sufficiently bright with a ten-foot reflector, to
show the Moon's spots, even the darkest of them. Such
similar phenomena were not perceived in the previous month,
despite using the same telescope. The volcano was not as bright
as his 4th May 1783 sighting (resembling a 4th magnitude star as
seen with the naked eye), though the latter was smaller in diameter.

1978 catalog weight=5 and Cameron 1978 catalog serial No. 418,
In 1948 Aug 09 at UT 02:40 Woodward (Toronto, Canada, sky very
clear) observed, using a telescope, a bright, bluish-white to
greyish-yellow, 3 sec duration flash in Earthshine. The flash
was between magnitude 0 to 1 if one were looking for a similar
magnitude star in the sky without a telescope. There was
possibly a very slight motion of the flash in a southerly
direction. Also there were two terminal bursts. Cameron suggsts
that this might have been a meteor? Ref: Moore, P.A. Guide to
the Moon (1953), p117. The Cameron 1978 catalog ID=508 and
weight=0. The ALPO/BAA weight=1.
On 1970 Jul 07 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3"
refractor, x60, x100, x135, seeing=good) observed the following in
Aristarchus: "Similar conditions as last night (#1264) but diminished
in brightness to 40% (to 6deg bright. Real phenom. in the dimming?)".
The Cameron 1978 catalog ID=1265 and weight=3. The ALPO/BAA weight=3.
On 1980 Nov 11 at UT17:35-18:32 G. Blair (Weir, Scotland, UK) at
17:35UT immediately noted that the Earthsine was extremeley bright. All
large detail easily seen on unilluminated disk. 17:38UT a definite pale
reddish brown tinge enveloped the Aristarchus area. 17:39 seemed to be
getting larger and more intense west (IAU) side. Attempted to contact
other observers. 17:40UT Aristarchus still had a bright central peak.
17:50UT fading a little from the west (IAU). 18:00UT slight revival in
brightness. 18:15UT effect still visible when Aristarchus set behind a
high western horizon. The two sketches supplied show the illuminated
region around the crater with extension to the west (IAU). P. Foley
(Kent) found thatAristarchus was bright enough in Earthshine to be seen
with the naked eye. Telescope in operation at 18:00UT and the entire
Aristarchus region was bathed in violet/rose colour with what appeared
to be a strong ray extending to the west (IAU). Detail could be clearly
seen inside Aristarchus crater such as the central zone, west and north
wall and rim in relief from point southeat to northwest. CED measure
0.8 (white), 0.9 (blue), 0.2 (red). No other reading in Earthshine gave
a measure in red. Observation ceased by 18:32UT as the Moon was very
low. ALPO/BAA weight=3.
Macrobius 1972 Apr 17 UT 20:10-20:45 Observed by Persson (Hvidore,
Danmark, 2.5" refractor x58 & x100, seeing=good) "Macrob. was a white
ring without outline or shadow. (shad. should have been seen--sun only
up 5deg alt. Something was raising albedo from 0 to surround." NASA
catalog weight=3 (average). NASA catalog ID #1328.
Proclus 1972 Apr 17 UT 20:10-20:45 Observed by Persson (Hvidore,
Danmark, 2.5" refractor x58 & x100, seeing=good) "Proclus not as clear
as usual" NASA catalog weight=3 (average). NASA catalog ID #1328.
On 1972 Apr 17 at UT 20:10-20:45 Hvidore (Denmark, 2.5" refractor, x58,
x100, seeing=good) noted a brightening of the dark limb between
Hercynian mountains and Cleostratus crater. Thought that it was due to
atmospheric disturbance. Cameron says similar to other reports e.g. No.
1156. The Cameron 1978 catalog ID=1330 and weight=1. The ALPO/BAA
weight=1.
On 1970 Jul 08 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3"
refractor, x60, x100, x135, seeing=excellent) observed the following at
Aristarchus: "Conditions again similar (to #1264). Brighter tonite(8
deg) than last nite. but not as bright as on the 6th. Pin pts. of light
very accentuated. The radial open hand extended fingers form not so
frequently, perhaps because of the larger crescent illum. now.".
The Cameron 1978 catalog ID=1266 and weight=3. The ALPO/BAA weight=2.
Cyrillus G 1983 Aug 13 UT 20:17-20:59 L. Paynter (Radcliffe,
UK, 22cm reflector, seeing III or better, transparency good).
Cyrillus G was relatively bright and surrounded by a shaded
area. On increasing the magnification from x65 to x130 he became
aware of a diffused "carise" colouration, in and around the
crater. The colouration was similar though to other spurious
colour on the Moon, but unlike other areas affected by spurious
colour, was more diffuse and spread out and not so concentrated.
In view of some uncertainty by the observer, ALPO/BAA weight=1.
