In 1825 Apr 22 at UT0030 Argelander (England) and Gobel (Koburg,
Germany) saw the following in the vicinity of Aristarchus: "Points of
light in center. In low magn. appeared as a small star, somewhat
scintillating. At higher magn. became larger & diffused. (date 1824 ?

On 1989 Apr 10 at UT01:30-02:00 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x64, seeing excellent) observed that Earthshine was not as
good as the previous night "~1/4 north shore looked unusually bright compared to other similar
features. BAA Lunar Section observation. ALPO/BAA weight=0.
Boussingalt 1860 Apr 24 UT 20:00? Observed by Schmidt (Athens, Greece,
7" refractor) "Noted weak glows on the crater he tho't prob. due to
wall reflections on floor" NASA catalog weight=0 (very unlikely to be a
TLP). NASA catalog ID #132. ALPO/BAA weight=1.
Bright spot (in dark part of Moon - confirmation of Arkhipov?). Cameron
1978 catalog weight=5 and Cameron 1978 catalog serial No. 418,
Proclus 1955 May 25 UT 19:30 Observed by Firsoff (Somerset, England,
6.5" reflector x240, seing=very good) "E. (IAU?) wall equally bright in
red and green filters, dull in blue, invisible in violet. (in p.c. time
given is 0730UT, but must have been 7:30PM loc. time." NASA catalog
weight=4 (good). Cameron 1978 catalog ID=594 and weight=4. 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.
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?)".

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.".

On 1885 Feb 19 at UT 19:00-20:00, Gray of England?, saw a small crater
(in it?) that was dull red with vivid contrast. The Cameron 1978
catalog ID is 247 and the weight=3. The ALPO/BAA weight=3.
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.
McClure vicinity 1976 Apr 04 UT 19:36-2009 Observed by McKay
(England, 3" refractor, x160), Savill (England, 10x50

"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,

lunation since July. The Cameron 1978 catalog ID=908 and weight=5. The
ALPO/BAA weight=2.
Posidonius 1821 Apr 07 UTC 18:00? Observed by Gruithuisen (Munich,
Germany) "Small bright crater in it was shadowless. Schroter also saw
it shadowless several X" NASA catalog weight=4 (good). NASA catalog ID
#87. ALPO/BAA weight=3.
In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of
twilight (Cameron says also seen by Gruithuisen, Henry and others at
times). Webb gives a low weight to his own observation, saying "for
want of better optical means". The Cameron 1978 catalog ID=130 and
weight=1. The ALPO/BAA weight=1.
Observations made by Challis of Cambridge, and N. Pogson of Hartwell,
both of the UK. Before the occultation, Saturn's rings were
distorted. A dark border was seen around the Moon. Just before
re-appearance a sea green colour was noticed. Cameron 2006
catalog extension ID=5 and weight=2-5. ALPO/BAA weight=1.
On 1993 Dec 19 at UT 16:00-17:00 S. Beaumont (Cambridge, UK, 12"
reflector, x230) observed in Theophilus that the "c.p. > reddish brown
tint to SW (on peak?)" but suspected that it was probably spurious
colour, however no colour was seen later. The ALPO/BAA catalog ID=469
and the weight=3. The ALPO/BAA weight=2.
On 1965 Oct 30 at 23:30-23:50UT Fehring and Garris (Parasmus, NJ, USA,
using a 2.4" refractor x88, seeing very good) saw a fuzzy area --
variations in shape and distinctness, seen in an area east of Atlas
crater. A drawing was made. It was noted that no other area had a
similar effect. Cameron 1978 catalog ID=909 and weight=3. ALPO/BAA
weight=3.
On 2012 Mar 28 at UT 20:45-20:50 Two unknown Italian
observers, reported on an on-line formum that they had
independently seen a distinct glow with a comma/drop shape.
One of them moved the Moon and the glow moved with the Moon.
It is uncertain how experienced the observers where. A chart
was provided which shows the lcoation of the glow in the
western side of Mare Imbrium. It is just possible that this
was Aristarchus in Earthshine, though that is very slightly
further west and south than the observers reported. ALPO/BAA
weight=1.
On 1881 May 04 at UT 20:00? Trouvelot (Meudon, France)
observed an unexplained light inside Eudoxus crater. The
Cameron 1978 catalog ID=222 and the weight=3. The ALPO/BAA
weight=3.
On 1994 Apr 17 at UT02:00 R. Zit (Madison, WI, USA) whilst observing a
grazing lunar occultation, found that Aristarchus (and the surrounding
region) was glowing in Earthshine. This was confirmed by D. Weier
(Madison, WI, USA) at 02:00 UT also. The ALPO/BAA weight=1.
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.
On 1970 Apr 13 at UT09:00-09:03 Whelan (Walters, New Zealand, using a
10" reflector) observed Menelaus to have a deep red cloud that seemed
to surge upward from outside the southern edge of the crater wall and
disperse around the outside edge, spreading out on reaching Mare
Serentiatis. All clear again though by 09:03UT, (Apollo 13 watch).
Drawing supplied. Cameron 978 catalog ID=1246 and weight=3. ALPO/BAA
weight=3.
Pitiscus 1981 Sep 05 UT ??:?? but assumed to be AM? which would make
it 00:00-03:00UTC. Observed by Slayton (Fort Lauderdale, Florida, USA,
8" reflector, ASA 64EK7 f/170, Kodak Kodachrome) photographed a bright
glow in the crater that appeared to move. Observer also reported seeing
it visually noting that it looked gray with a tinge of red. For further
information see p266 of Sky & Telescope (1991, March). Note that
Cameron gives the date and UT at 1981 Sep 06 UT 01:00-01:30, or one day
later. I will use this date and time from now on. The Cameron 2006
catalog ID=152 and weight=5. The ALPO/BAA weight=3.
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.
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.
Albategnius 1972 Jun 18 UTC 19:20-19:25 Observed by Schnuchel (13.25E,

Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson,
Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw
something in Proclus, alerted Jamieson who saw nothing unusual
at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw
Proc. fluctuate. Red & blue filters showed some reduction in
brightness. E. edge showed darkening, but not as dark as in
shadows. 10 min later, returned to normal. (Sparks confirmed
Dean)." NASA catalog weight=5. NASA catalog ID #1267. ALPO/BAA
weight=3.
1970 Jul 11 UT 20:35-20:45 During a TLP alert for Proclus, Jamieson

reduce over time." An ALPO report. The ALPO/BAA report=2.
2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw
Mons Pico to be incredibly bright. Adee reported naked eye visibility,
though this does not show up in later CCD images. Jarwaski saw another
nearby Mt very bright as well. This has been assigned an ALPO/BAA
weight of 1, though I suspect it is just normal for Pico to get quite
bright at sunrise.
Patches of brightness seen in the area between craters Aratus and Joy.
Seemed to the observer to be perhaps slightly brighter than one would
expect - the observer thought that their observation only barely
constitured a TLP but decided to send the report in anyway. This
has been assigned an ALPO/BAA weight of 1.
Plato 1918 May 20 UT 18:00? Observed by Markov (Russia) "Brightness in
shadow of the light sector & 1 spot" NASA catalog weight=3 (average).

8" reflector and 3" refractor, seeing poor) found that the west wall of
Eimmart was unusually bright (8.3) and apparently it was almost as
bright as the "WEBS(of Aris?) at its brightest". The crater was
apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID=
228 and the weight=3. The ALPO/BAA weight=2.
Purbach 1970 Apr 14 UT 12:00-14:00 Observed by Osawa (Awajt-Shima,
Japan, 8" reflector, x288) "Photos in blue and orange taken. Ill-

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

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.
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

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

Proclus 1984 Jul 06 UT 20:29-20:43 light green spot observed by Madej
(England) in the central region. No colour seen elsewhere. At 20:10
Foley (Kent, UK, 12" reflector) had seen a small extending of darkening
in the south east floor (not present 2 hours before) and a lot of fine
detail - though everything was normal again by 22:50UT. At 22:15 Amery

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.
A track of reddish light, like a beam, was seen
crossing the shadowed floor of Plato.This TLP has an ID

less so (?) and the shape changed. When viewed through a green filter
it was less distinct. "Change with two other filters. Polarizer gave a
circular shape with a knot on SE side & W58 in White." The measured
brightness of Proclus was 9 on three sides and 8.5 on its west rim. The
floor was 5.5, but the dark spot was 4. Alphonsus, Bullialdus,

detected "purple"in the vicinity of Aristarchus crater and this was
stongest on the north and north west external rims, however there was
no "violet glare"from inside the crater. However the region of the
central peak was very bright - though he could not detect the central
peak. The brightness of the TLP was 4.5 and it should normally be 3

seen on the crater. There was also violet on the northen wall of
Herodotus crater and the Cobra Head. Īt appeared dark blue in the blue
filter", the surrounds remained gray". Apparently on the 26th the"ring

watch. The Cameron 1978 catalog ID=1127 and 1128 and weight=5. The
ALPO/BAA weight=4.
On 1990 Feb 18 at UT18:00 Schroter(Lillienthal, Germany) saw a small
hazy spot of light in the vicinity of Aristarchus crater. The Cameron
1978 catalog ID=64 and weight=4. The ALPO/BAA weight=1.
On 1822 Jun 23 at UT 21:20 Ruppell (Germany?) observed a "lunar
volcano" in Aristarchus. The Cameron 1978 catalog ID=96 and the weight=
1. The ALPO/BAA weight=1.
On 1969 Jul 18 at UT 23:00-00:15 Ronaldo R. de F. Mourao (Rio
de Janeiro, Brazil, 8" refractor, 10" refractor(?), 19.5"
refractor) saw a TLP in Aristarchus that they had seen
earlier in the evening involving: Luminosity in Aris. strong
& prolonged northward with impression of 2 lum. pts. (Apollo
11 watch). The Cameron 1978 catalog ID 1159 and weight=4. The
ALPO/BAA weight=1.
On 1989 May 10 at UT02:30-03:50 M. Wisniewski (Chicago, IL, USA, 8" &
6" reflector, x123) found Aristachus to be unusually bright and
"glowing" as a blue-white magnitude 8 disk, though it faded close to
the end of his observing period (02:30-02:50). A ray from Tycho could
be seen in the direction toards Aristarchus crater. Darling (Sun
Praire, WI, USA, 12.5" reflector, x50) found Aristarchus Z to be both
bright and diffuse. The Cameron 2006 catalog ID=363 and the weight=2.
The ALPO/BAA weight=1.
On 1989 May 10 at UT01:54 D. Weier (Sun Praisre, WI, 12.5" reflector,
x50?) detected a flash east of Grimaldi crater "like a small
electrostatic charge - radiated out like a decorative plasma lamp - not
fuzzy. Darling (Sun Praisre, WI, 12.5" reflector, x50?) saw it but
dismissed it as he had seen it many times before (in same loc?). The
Cameron 2006 catalog ID=363 and the weight=2. The ALPO/BAA weight=2.
On 1994 Jan 16 at UT19:30-21:10 D. Strachen (England, UK, 4" refractor,
x21 and x143) whist looking at an occultation of ZC3453, saw a bright
spot in Earthsine, just north of Aristarchus (47W, 25N) at position
angle 30deg-40deg, only a little way in from the limb. It appeared like
a star through haze and a few seconds of arc in diameter. It was
Visible for more than 1 hour until 20:50UT although had faded somewhat
by that time. However J. & M. Cook (Frimley, UK, 12" reflector, x143
and x244) saw nothing in Earthshine from UT 20:02-21:10. The Cameron
2006 catalog ID=472 and weight=1. The ALPO/BAA weight=1.
Cape Agarum 1995 Feb 05 UTC 18:10-19:20 Observer: P.Moore (Sussex, UK,
15" reflector) - obscuration seen - Antoniadi II seeing, and Moon high
up. BAA Lunar Section report. ALPO/BAA weight=3.
On 1970 Jun 08/09 at UT 23:30-00:00 Celis (Quilpue, Chile, 3"
refractor, x60, seeing=good?) observed lots of activity in the
Aristarchus region - blue luminous star-like points, frequently
appearing. Cameron comments that maybe atmospheric effects. The Cameron
1978 catalog ID=1260 and weight=1. The ALPO/BAA weight=1.
On 1939 Feb 23 at UT17:00 Malakhov, Filippoova (Russia) observed an
intensive luminescence in background of ashen light that had ceased in
March, in Aristarchus (confirmed of Andrenko - says Cameron). Cameron
1978 catalog ID=446 and weight=5. ALPO/BAA weight=3.
On 1969 May 21 at UT 03:40-04:25 Kohlenberger (Fullerton, CA, 12"
reflector), Harris, Miller (Torrence, CA, 12" reflector), Bell and
Calkins (Ojai, Duarts, CA, USA), Kelsey (West Covins, CA, Riverside,
CA, USA) observed scintillations in Aristarchus - Cameron says
independent observations?). Members of Astronet took part in this
observation. Kelsey saw a brightening but not on the order of seconds
as others reported. Cameron suspects an atmospheric effect and also
comments that this was during the Apollo 10 watch. The Cameron 1978
catalog ID=1130 and weight=2. The ALPO/BAA weight=2.
On 1881 May 04 UT 20:00 "Gamma" a psuedonym for an astronomer
(Germany?) observed Aristarchus to be be a very bright 8th magnitude
star with pulsations. The Cameron 1978 catalog ID=221 and the weight=3.
The ALPO/BAA weight=2.
