Aristarchus 1972 Mar 30 UTC 23:03-23:05 Observed by Kufer (11.5E,
48.25N, 110mm reflector) "A sudden brightening, but observations
limited by cloud" Ref: Hilbrecht & Kuveler Moon & Planets (1984) Vol
30, pp53-61.
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.
On 1981 Oct 15 at UT06:03-06:51 D. Louderback (South Bend, WA, USA, 3"
refractor, seeing=1-2 and transparency=5) observed that the brightenss
of 4 sun lit bright spots differed in red and blue light. "Appeared as
a cross. the 2 points A & D on his sketch (index) were affceted. They
were 10 pts dimmer in red than blue. Not due to seeing as they did not
fluctuate (as did the seeing)." This report came from the Cameron 2006
catalog and had an ID No. of 156 and a weight=3. The ALPO/BAA weight=2.
On 1981 Oct 21 at UT 11:35-11:48 B. Hobdell (St Petersberg, FL, USA,
10" reflector) found that the south peak of Plato on floor glowed white
at 11:35UT, then a milky shade spread all aorind Plato's floor
(previously completely shadow filled). The needle like shadows started
to be indistiguishable through the sunlight (dawn on Earth). The cloud
like feature was washed out by daylight at 11:48UT and conformed to the
"white area except a tail that reached the cetre of Plato" Spurious
colour was not seen. The Cameron 2006 catalog ID=157 and weight=3.

On 1973 Feb 23 before UT 23:00 P. Moore (Selsey, UK) reported
activity detected in Aristarchus. Fitton ovbserved from 23:40-
00:20 and obsrved nothing unusual except for a minute white
area, about 1 km in diameter about 2km north of the central
peak. This spot kept on coming and going in the seeing. Fitton
regarded this as a permanent spot, although he had never noticed
it before. Nor could Fitton see the colour that he had noticed
on the previous night. A BAA report. ALPO/BAA weight=1.

(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.

Picard 2002 Sep 10 UT 02:30-03:21 Observed by Gray (Winnemucca, NV,
USA, 152mm refractor x248,S=2-3, T=5) "observed in White light and
through Wratten Red 25 and Blue #38A filters. The crater through the
Red 25 filter looked very similar to the view in White light. Using the
Blue 38A filter Picard almost dissapeared - it looked like a dim,
faintly observable black spot with the sunlit, east facing west crater
wall barely visible. Observer had not observed Picard very often, so
was not too familiar with it but it seemed odd that it almost vanished
through the blue filter." ALPO observational report. The ALPO/BAA
weight=3.
In 1965 Jul 02 at UT 04:20-05:50 Albert and Welch (Azuss, CA, USA, 8"
reflector, x375) and Emanuel (West Covina, CA, USA, 4.5" reflector)
observed 4th magnitude star-like flashes to blotches in Aristarchus, in
ashen light. Cameron says that this is independent confirmation and
also that the date in MBMW is 7/1/65 which is local time + 2nd UT. The
Cameron 1978 catalog ID=881 and weight=3. The ALPO/BAA weight=3.
In 1824 May 02 at UT 21:00-21:15 Gobel (Germany, seeing = excellent)
saw near Aristarchus (47W, 23N) a soft (matte) light like a star seen
through mist. Brightness increased suddenly to magnitude 9-10. After
several seconds it became weak, finally disappearing. repeated this 3
to 4 times in 15 minutes. The Moon was a very narrow sickle shape and a
major feature could be seen in Earthsine. The date given was 1821 but
Cameron says it is 1824. The Cameron 1978 catalog ID=88 and weight=4.
The ALPO/BAA weight=3.
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

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

Hercynian mountains and Cleostratus crater. Thought that it was due to
atmospheric disturbance. Cameron says similar to other reports e.g. No.

On 1969 May 20 at UT 19:35-20:30 Gomez (Spain, 12" reflector) observed
blue-white pulsating light in Aristarchus that illuminated the inner
walls - it was maximum at 19:55UT. This observation was made during the
Apollo 10 watch. The Cameron 1978 catalog ID=1128 and weight=5. The

On 1975 Mar 18 at UT 00:57-04:00 Reiland, Brown and Lojeck (Pittsburgh,
Pennsylvania, 6" reflector x45 and 8" reflector x200, photos taken)
observed the following at Aristarchus: "While obs. Earthshine on moon,
saw it glowing -- a bright steady star-like glow, est. at 5-8th mag.
First noted at 0057h. Obs. other obj. then came back to it. It was

On 1969 May 21 at UT 20:00-21:00 Brandli and Germann (Switzerland, 6"
refractor) observed a slow orange-red blinking on the surrounding area
of Aristarchus. It was seen less markedly the next night. Wald (Zurich,
Switzerland) noted at 20:30UT that the crater was pink (Confirmation
says Cameron) - this was during the Apollo 10 watch. The cameron 1978
catalog ID=1131-1132 and weight=5. The ALPO/BAA weight=4.
Fracastorius 1973 Mar 09 UT ~19:57 Robinson (Devon, UK) saw a
Moon Blink (colour) in this crater. This crater is long
suspected of giving permanent blinks due to natural colour. The
ALPO/BAA weight=1.
Cepheus A 2000 Oct 04 UTC 08:15-08:50 Observer: Maurice Collins
(New Zealand, 90cm ETX) - observer noted that crater was
extremely bright - wasn't sure if this was normal and at the
time rated it as the brightest (contrasty?) crater that he had
ever seen on the Moon. Many years later he suspected that he may
have mis-identified the crater. This still leaves us with thr
problem as to why a crater should be so bright in this region,
and if so, which one? ALPO/BAA weight=1.

On 1969 May22 at UT2045-2105 Wald (Zurich, Switzerland) observed the
pinkish colour in Aristarchus was less marked tonight. The astronauts
were alerted and at 22:12 reported no activity but could see the crater
and Earthshine was strong near the terminator. Apollo 10 watch,
spacecraft far from the terminator. The Cameron 1978 catalog ID=1134
and the weight=2. The ALPO/BAA weight=2.
On 1915 Apr 21 at UT 1800? Houdard (France) noticed a special
occurrence south of Posidonius which he took as evidence of water
vapor. The Cameron 1978 catalog ID=351 and weight=3. The ALPO/BAA
weight=2.
A.S.Williams of West Brighton, UK, using a 2.75" Acromatic refractor
(x75, definition good, but it was too windy to use the 5.25") noticed
that the mare was a mass of light streaks and spots. This was not
considered unusual, but these features were unusually plain, distinct
and brught, especially the streaks. The observer could not recall
seeing the streaks so bright and clear with this instrument before, and
indeed hardly ever with the larger 5.25" telescope. The observer
continued to observe Mare Crisium on many nights for several months and
comments that such an unusual exhibition was later seen perhaps once
every 2-3 lunations. They are uncertain how much this effect depends
upon the state of the Earth's atmosphere. This TLP does not make it
into the Cameron 1978 catalog and so may not be a TLP - however it has
been included, just in case, and to try to understand what was actually
seen. ALPO/BAA weight=1.
Mons Piton 2022 Aug 04 UT 19:41-20:10 T. Smith (Codnor, UK,
16inch Newtonian, x247, Seeing IV) mountain was very bright
and red around its eastern slopes. An examination of the
bright and contrasty Proclus crater revealed that to be
relatively colour free compared to Piton. An examination of
other features, north and south along the terminator revealed
some tinge of coloiur but not as strong as on Mon Piton. Mons
Piton examined with a yellow filter at 19:50 and still showed
red along the eastern side, other features along the
terminator had no colour through the filter. Video images by.
A.Cook (Newtown, UK) made earlier at 1929 & 19:40 UT, (in the
SWIR (1.5-1.7 microns) did not reveal Mons Pico as especially
bright - but resolutioin was poor. A friend of Smith, phoned
up the next day to say that they saw a mountain on the limb
exhibiting red on the 14th August. Probably the redness was
due to atmospheric spectral dispersion as the Moon was low,
and it was especially visble on Mons Piton as this is an
exceedingly contrasty object on the terminator. ALPO/BAA
weight=1.
On 1887 Nov 23 at 16:15-17:00 UT Von Speissen & others of Berlin,
Germany, using a 3.5" refractor (x180), saw a "Triangular patch of
light (time in Middlehurst catalog wrong? Moonrise was at > 18:30h. If

catalog ID #840. ALPO/BAA weight=3
On 1972 Apr 21 at UT19:01 Mattingly (Apollo 16 commander, in orbit
around the Moon, using his naked eyes) saw a bright flash from below
his horizon on the lunar farside (approximate longitude=180 deg). he
was dark adapted at the time. However no sesimic event was recorded and
so Cameron suspects that this was not a meteor impact but a cosmic ray
striking his eye. The Cameron 1978 catalog ID=1331 and weight=3. The
ALPO/BAA weight=3.
On 1990 May 03 at UT 02:03 D. Darling (Sun Praire, WI, USA, seeing
steady) observed a point of light inside Alphonsus just to the north
of the central peak, along the "center ridge". It was seen again, half
way between the central peak and the noth west rim - along the ridge.
All other features were normal. The Cameron 2006 catalog ID=403 and the
weight=3. The ALPO/BAA weight=3.
A track of reddish light, like a beam, was seen
crossing the shadowed floor of Plato.This TLP has an ID

Plato 1882 Mar 27 UTC 20:10-21:00 Observer: A.S. Williams (Brighton,
UK, 5.5" saw the shadow filled floor of Plato at Sunrise with a
"Glowing and curious milky kind of light". About 1 hour after sunrise
at Plato, there was no trace of this effect. The TLP filled the whole
floor except at a quarter of the diameter from the east wall which was
actually quite black. The observer saw a curious phosphorescent glimmer
at sunset (April11th?). Cameron comments that Birt, Nelson and Waugh
saw obsecuring mist or fog in Plato on many occasions. Cameron 1978

On 1979 Dec 27 at UT 05:32 D. Louderback (South Bend, WA, USA, 6"
reflector x240, seeing=3-6/10 and T=4) noticed "2 small high-sun areas
nr. Eimmart - brightening around Mare Crisium, except for interior of
Proclus - in blue light. They were brighter than 2 spots on Cap.

On 1965 Sep 03 UT03:00-05:00 D.Harris (Located near Whittier
College, Whittier, CA, USA, using a 10" f/8.2 Newtonian
reflector, x78 & x208, seeing 5-6, transparency 2-0) observed a
ridge obscured SSW of Ross D. No drawing was made, only a
written description. "Ridge not visible near crater; possible
white patch 1/3 Ross D diameter" The ridge is the wrinkle ridge
extending NNE from Ross D, a well established often visible
feature. Harris comments that this was not one of the better TLPs
seen near Ross D, and there were no independent observers,
neverless he was ceratin of this being a TLP, and it was
consistant with other activity seen near this crater between 1964
and 1970. Cameron 1978 catalog ID 891 and weight=3. ALPO/BAA

On 2009 May 03/10 UT23:20-00:11 P. Abel (Leicester, UK, 20cm reflector,
x312, seeing III-IV) observed that the north east wall was slightly
brighter than would have been expected, slightly blurred (not seeing
related blurring) and had a strong orange-brown colour. No spurious
colour seen elsewhere. A change in eyepieces showed the same effect. No
luck in alerting other observers. A drawing was made at 23:20UT and
finished at 00:12UT. At 23:12UT part of the inner NW floor had a dull
brown colour, whereas before it was grey.By 00:11UT the colour effect
was fading and by 00:18 seeing condirions were too bad to continue. M.
Cook (Mundesley, UK, 9cm Questar telescope, x80, x130, seeing III,
transparency moderate to good) had observed Tycho earlier in the
evening at 22:15UT, but had seen no signs of colour. W. Leatherbarrow
(Sheffield, UK, 8cm scope, high cloud interuptions and bad seeing) had
taken monochrome images at UT 20:07 and 20:10, but these showed nothing
unusual, and he checked the crater visually at 00:00-00:30, but
detected no colour, although the Moon's low altitude contibuted to poor
seeing conditions and some spurious colour was seen. CCD images from M.
Collins (Palmerston North, New Zealand) taken at 00:46UT showed
nocolour apart from spurious colour on contrasty edges, in no way
reflecting what was seen early by P. Abel. The ALPO/BAA weight=2.
Observer made a drawing over a period of 30 minutes. Upon
examining drawing, and comparing with photos made under
similar illumination was struck by the abnormality of a
a small white blob in the north east corner of the shadowed
floor. There should be no raised topography between the wall
and the central peaks that could give rise to this. The making
of the sketch overlapped with an earlier drawing made by Rony
de Laet (Belgium) which did not show this blob. Subsequent attempts
to find sketches/images at very similar illumination angles have
failed to show the blob in the north east corner of the chadowed
floor. ALPO/BAA weight=3.
Birt 1955 Apr 15 UT 03:20-05:00 Observed by Capen (California

Ireland, 10" refractor, x140) "Eng. moon blink sys. blinks inside the
crater. Very dubious due to low alt. of moon." NASA catalog weight=1
(very low). NASA catalog ID #982.
Gassendi 1967 Jun 18 UT 22:50-23:59 Observed by Whippey
(Northalt, England, 6" reflector?) "Faint redness outside NE &
SE wall of crater." Moore (10" Armagh refractor, x360) was
observing earlier 22:10-22:40, with and without a Moon Blink but
detected no redness, however his observing conditions were not
very good at the time. NASA catalog ID #1039. NASA catalog
weight=3. ALPO.BAA weight=2.
Aristrachus 1966 Jul 29 UT 03:40 Observed by Simmons (Jacksonville, FL,
USA, 6" reflector x192, S=7, T=4-5) and Corralitos Observatory (Organ
Pass, NM, USA, 24" reflector + Moonblink) "Spot on S.wall vis. only in
red filter, brightness 8deg. Slightly brighter than surrounding wall.
No confirm. Says it might be part that reflected better. Not confirmed
by Corralitos Obs. MB." NASA catalog ID #968. NASA catalog weight=1
(very low).
Aristarchus 1972 Apr 25 UTC 19:15-19:20 Observer Ventzke (located at
48.67N, 12.00E) - diffuse brightening on inner N. wall, reddish. 60mm
refractor used. Ref. p53-61 of Hilrecht & Kuveler Moon & Planets vol
30, 1984.
In 1950 Aug 25 at UT 10:55 T.Saheki (Osaka, Japan) observed a
stationary yellow-white flash on the Moon of duration 0.2 sec
and mag 6.5. Cameron suggests that this was a meteor. The
Cameron 1978 catalog ID=536 and weight=0. The ALPO/BAA weight=1.
Two small conical mountains, near last 4th May eruption,
close to the third one that he had seen before, but not
these two. They were not on any map.
SE of Langrenous 1947 Aug 28 UT 21:00? Observed by Baum
(Chester, England) A long mountain mass, on limb to the SE of
Langrenus crater, had a decidedly bluish cast. To the north, on
the limb, were several ordinary peaks appearing in profile and
some were sharp and pointed. NASA catalog ID=498. NASA catalog
weight=3. ALPO/BAA weight=2.
Proclus 1950 Jul 27 UT 02:56 Observed by Bartlett (Baltimore,
MD, USA) described in the NASA catalog as: "C.p. of Proc.
disappeared)" 5" reflector used at x100, NASA catalog weight=4.
ALPO/BAA weight=2.
Herodotus 1950 Jul 27 UT 03:56 Observed by Bartlett
(Baltimore, MD, USA) described in the NASA catalog as: "Pseudo
c.p. in Herod. Drawings. (Similar to NASA catalog event #523)"
5" reflector used at x100, NASA catalog weight=4. ALPO/BAA
weight=3.
Torricelli B 2002 Oct 18 UTC 20:56-21:59 Observer: G.North (UK, 8"
reflector, x134, Seeing Antoniadi IV, Transparency good) - thought that
Torricelli B was perhaps a little brighter than expected, especially
when compared to Moltke and Censorinus based upon past recollection of
relative brightnesses at this colongitude). Slight bluish tint seen as
well. The ALPO/BAA weight=1.
On 1990 May 09 at UT08:24-08:28 D. Louderback (South Bend, WA, USA, 3"
reflector, x150, Clears sky) noticeed in Promontorium Agarum (Cape
Agarum), that at 08:24UT the west point (C) dimmed to a brightness of
6.5 before ragaining its normal brightness at 7. Cameron comments that
these are wedge measurements equivalent to 0.5 steps in Elger's
brightness scale. No other effects noticed elsewhere. The Cameron 2006
catalog ID=404 and the weight=3. The ALPO/BAA weight=2.
On 1963 Nov 01/12 at UT 22:30-03:00 P. Moore (UK, 12" reflector)
observed something unusual in Aristarchus/Copernicus/Kepler -
the Cameron catalog is not very clear which. The Cameron 1978
catalog ID=779 and weight=5. ALPO/BAA weight=1.
On 1963 Nov 01/12 at UT 22:30-03:00 P. Moore (UK, 12" reflector)
observed something unusual in Aristarchus/Copernicus/Kepler -
the Cameron catalog is not very clear which. The Cameron 1978
catalog ID=779 and weight=5. ALPO/BAA weight=1.
On 1963 Nov 01 at UT 00:20-00:35 Kopal and Rackham (Pic du
Midi, France, 24" reflector) observed in Kepler an
enhancement in red light at 672.5nm and 545.0nm. Luminescence
~86% +/-3% of background. According to the Cameron catalog,
Moore(12" reflector, UK) noted something unsual between 22:30
and 03:00 but this might apply to Kepler, Coperncius, and/or
Aristarchus and that was seen 23:30-03:00? - the catalog is not
very clear. The Cameron 1978 catalog ID=779 and weight=5. The
ALPO/BAA weight=4.
On 1963 Nov 02 at UT 00:00? Scarfe (Cambridge, UK) observed a spectral
line dpeth anomaly? The cameron 1978 catalog ID=780 and weight=5. The
ALPO/BAA weight=4.
