On 1790 Jan 17 at UT 1800 Schroter (Lilienthal, Germany) observed a
small hazt spot of light in the vicinity of Aristarchus crater. The
1978 Cameron catalog ID=65 and the weight=4. 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.
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.
Cameron's 1978 ALPO catalog has a TLP ID No. of 33 and a weight of

In 1824 May 01 at UT 21:00 Gobel (Koburg, Germany) observed near
Aristarchus, a blinking light of magnitude 9-10, in Earthshine. The
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 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
weight=0. The ALPO/BAA weight=1.
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 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.
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.
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.
SE of Ross D 1964 Aug 16 UT 04:18-05:20 Observed by Harris and
Cross (Whittler, CA, USA, 19" reflector?) "Bright area.
Condensations varying with time" NASA catalog weight=3. NASA
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.
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.
Clavius 1915 Apr 23 UTC 20:00 Observed by Cook (England?) "Narrow
straight beam of light from crater A to B" NASA catalog weight=1 (very
poor). NASA catalog ID #352. ALPO/BAA weight=1.
On 1972 Apr 22 at UT 18:58-00:28 Hopp (75mm refractor, 1200mm focal
length,transparency 4 out of 5 and seeing 4 out of 5, located at 52deg
30' N and 13deg 15'E) Censorinus brighter than normal relative to
Proclus. Published in Hilbrecht and Kuveler, Moon and Planets, 30
(1984) p53-61. ALPO/BAA weight=1.
Birt 1955 Apr 15 UT 03:20-05:00 Observed by Capen (California
Seeing=Excellent) "Small craters between Birt & wall were invis. at
times under excellent seeing, while craterlets on w.side were
continually obs." NASA catalog weight=4 (high). NASA catalog ID #586.
On 1882 Jan 29 at UT 17:00-17:30 an unknown observer noted an unusual
shadow in Eudoxus crater. The Cameron 1978 catalog ID=227 and the
weight=2. Reference: Sirius Vol 15, 167, 1882. The ALPO/BAA weight=2.
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.
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.
