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 1790 Jan 17 at UT 1800 Schroter (Lilienthal, Germany) observed a

1978 Cameron catalog ID=65 and the weight=4. The ALPo/BAA weight=1.
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.

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.
Note the month or day must be wrong!
On 1990 Apr 28 at UT 01:19-01:25 F. Graham (Marshall TWP, OH, USA, 6"
reflector) during a failed attempt to observe the occultation of X6493
that was thwarted by clouds, noticed that Gassendi was "Gass,>>,>Aris
or anything else". The crater had a "milky lustre". It is possible that
another occultation observing group may have a video of the Earthshine
at this time. Darling (Sun prairem WI, USA, 20x50 binoculars) could not
see Earthsine, though the sky was bright at the time. The Cameron 2006
catalog ID=402 and the weight=0. The ALPO/BAA weight=1.
William Herschel and Mrs Lind saw a red, 4th magnitude brightness, less
than 3 arc sec in diameter. Herschel believed that he was seeing a
lunar volcano in eruption.
A guest star trespassed against the moon. Cameron
suspects that this was a meteor? ALPO/BAA catalog weight=1.

ALPO/BAA ID=99 and the weight=4. The ALPO/BAA weight=3.
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 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.
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.
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.
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.
In 1963 Oct 22 at UT 21:00? Andre (Belgium, 2.25" refractor) noticed
that Posidonius A's shadow was not seen when it should have been seen.
The Cameron 1978 catalog ID=777 and weight=3. The ALPO/BAA weight=2.
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
still there -- till moonset (@0500h). Saw it in other telscopes &
Lojeck took photos. (photo shows Aris. prominent, but also LaLande,
Pytheas & Timocharis. 2 prs. in Aris. but there are other pts on the
print, it may be grain)". The Cameron 1978 catalog ID=1404 and
weight=5. The ALPO/BAA weight=2.
On 2012 Mar 28 P. Grego (Cornwall, UK, seeing II, 100mm
refractor, x132) observed a patch of light just inside the NW
rim of Menelaus on the shadowed wall or floor. Computer
visulaiztions of the illumination conditions using a digital
elevation model failed to produce this effect. ALPO/BAA weight=3.
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.
Lunar volcano, seen on the dark side, as bright as a
6th magnitude star,
A bright spot was seen. Cameron 1978 catalog
ID=40 and weight=3. ALPO/BAA catalog 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.
In 1982 Sep 24 at 22:45-23:40 K. Marshall (Medellin, Columbia) saw in
Theophilus an obscuration on the south west wall close to Cyrillus and
furthermore it had a red / mauve colouration (seen best in a 12mm Ortho
eyepiece). Through a Wratten 15 yellow filter the region was quite
bright. At23:40UT the obscuration faded. There was plenty of detail in
the region between Theophilus and Cyrils. The Cameron 2006 catalog ID=
184 and the weight=3. The ALPO/BAA weight=3.
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.
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
year =1887, age=8.8 days & time OK. must be same observation as ID=256
in Cameron 1978 catalog - note similarity of names and also the
reference date). Cameron 1978 catalog ID=258 and weight=1.
Peirce A (Swift=IAU name) 1937 Mar? 23? UTC 22:00 Observed by Wilkins
(England, UK, 12.5" reflector) "Obscuration on floor if crater. Crater
invis. (similar to #394, 396)." NASA catalog weight=4 (high). NASA
catalog ID #412. Note this is almost certainly supposed
to be 1934 Dec 23!

Alphonsus 1967 Aug 13 UT 18:40-18:55 Observed by Horowitz (Haifa,
Israel, 8" reflector?) "Glow or hazy patch seen while using filters.
Brighter than background. Not seen after 2055 or next nite" NASA
catalog weight=3 (average). NASA catalog ID #1041.
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
No. of 17 in Cameron's 1978 catalog and a weight
of 3. It has an ALPO/BAA weight of 2.
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
catalog ID=229 and weight=3. ALPO/BAA weight=3.
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.
Agarum rated 8.5 & Proc. 9. Not as bright next night. Probably a real
blue light brightening". Cameron 2006 catalog ID=79, location on Moon:
(70E, 23N) and weight=4.
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
weight=2.

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.
Birt 1955 Apr 15 UT 03:20-05:00 Observed by Capen (California
Seeing=Excellent) "Small craters between Birt & wall were invis. at

On 1975 Mar 22 at UT22:10-22:25 T.Flynn (Edinburgh, UK, 30cm
Newtownian, x75) observed 3 large areas on the floor of Plato to be
delicately darker in the blue filter. There were of different darkness.
He did not regard these as TLP, but permanent blinks. This is a BAA
report. The ALPO/BAA weight=1.
On 1991 May 24 at UT 00:05-00:08 UT Romualdo Lourencon (Sao
Paulo, Brazil, 60mm refractor, seeing=III) detected a circular

(Cambridge, England, 8" reflector, x160, S=G) "Had misty
portion of SW(ast. ?) floor from 2030-2105h at which time it
was gone. Clearly seen, had ill-defined boundaries & was an
easy obj. to see. Alt.=33 deg. (Apollo 10 watch)." NASA

Gassendi 1967 Jun 18 UT 21:10-22:30 Observed by Whippey
(Northalt, England, 6" reflector?) "Faint redness outside NE &
SE wall of crater." Moore (10" Armagh refractor, x360) was
observing too 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.
2004 Jul 28 UT 07:25-07:31 R. Dewitt (Transparancy very poor due
to forest fire pollution - Moon looks red, USA, location: Mill
Creek, WA) observed several pin point-like orange flashes of
light occur (2-5 sec duration each and static wrt the Moon's
surface) across the bright illuminated side of the Moon with the
naked eye. Other much fainter, almost instantaneous sparkles
were seen. The brightest flash seen was of 5 sec duration.
Switching to binoculars (15x45, another fainter one was seen
too. Binouculars were handed to wife, who also confirmed similar
flashes. The ALPO/BAA weight=2.
Plato 1966 Sep 25 UT 23:12-23:35 Observed by Moseley (Armagh, Nortern
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.
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.
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.
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 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.
