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 1988 Apr 18 at UT 19:00 R. Manske (Madison, WI, USA) observed that
Aristarchus? was glowing in Earthshine. Weier (Madison, WI, USA)
detected it easily in 7x50 binouculars. Spain (Fairfield, KY, USA)
though detected no TLP, nor could he see Aristarchus. The Cameron 2006
catalog ID=324 and the weight=0. The ALPO/BAA weight=1.
Southern cusp obseved by H.Hill (UK) on 1992 Apr 04 at solar
selenographic colongitude=294.Observer noted that the southern
cusp was extended by 350" - the effect appeared "atmospheric".
Note that this is almost certianly not a TLP but is worth
checking out if the libration and solar colongitude is similar,
just to verify that this is what the Moon normally looks like.
ALPO/BAA weight=1.
On 1970 May 08 at UT 23:00-23:30 Celis (Quilpue, Chile, 3" refractor,
x60, atmosphere turbulent) observed in the Aristarchus region a clear
line(?) and several star-like points. Cameron suspects atmospheric
effects due to low altitude and turbulence? The Cameron 1978 catalog
ID=1259 and weight=1. The ALPO/BAA weight=1.
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.
On 1970 Jul 06 at UT 22:45-23:45 Celis (Paso Hondo, Chile, 3"
refractor, x60, x100, x135, seeing=very good) saw Aristarchus as an
outstanding bright patch (10 deg bright) electric blue colour, every 10
sec groups of 3 or 4 separate sparkles for 10sec then a period of calm
for 30sec-1min. At 130x was almost constant form. Sometimes the form
would be radial like an open band with extended fingers. This was
observed in the dark part of the Moon and Cameron suspects atmopsheric
effects. The Cameron 1978 catalog ID=1264 and weight=2. The
ALPO/BAA weight=2.
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 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.
East of Picard (56E, 15N) 1877 May 15 UT 20:30 Observed by an
unknown observer (in England?) "Bright spot. (white patch)
there unlikely to be bright at sunrise normally)." NASA
catalog weight=3. NASA catalog ID #189. ALPO/BAA weight=2.
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.
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,
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?)".
The Cameron 1978 catalog ID=1265 and weight=3. 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 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.
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.
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 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 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.
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.
SW of Pico 1844 Apr 25 UT 20:00? Observed by Schmidt (Athens,
Greece, ? refractor) "A bluish glimmering patch of light not
quite within the dark side" NASA catalog weight=4. NASA
catalog ID #123. ALPO/BAA weight=3.
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-
defined obscur. in blue photo in S. part of crater compared with
orange. (neg. is so faint it is doubtful. Apollo 13 watch. Similar to
Alter's findings in Alphonsus)." NASA catalog weight=2 (low). NASA
catalog ID #1250.
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.
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.
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

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

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.
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
(Reading, UK) found a large dark spot on the south east floor. Other
observers: J and A.cook (Frimley, England) could not confirm but their
seeing was IV and tranparency was poor" Mobberley found no colour and
also no detail on the floor. BAA Lunar Section Report. Cameron 2006

hills, then why would the cental areas, presumably the higher
parts, be dark - when the contrary is usually the case?

slightly in blue light too. By 22:48 there was activity on the crater
floor i.e. the four bright spots were visible in white light but not in
red. In blue the central spot was seen and there were dark radial
streaks to the south wall and south east. At 22:50 there was a loss of
detail. Other craters were normal. At 23:08 the floor was dark in red,
but some details were visible in blue. the effect had finished by
23:35. At21:34 J-H Robinson found Plato to be normal and no blinks,
though floor clearer in red than in blue, however the floor detail had
gone by 21:57. Blair suspected a dusty patch in north of Plato,
especially in red light. at 21:57 and it started spreading at 21:13,
then east at 21:15 and then north. Though it faded at 21:25 but was
back again at 21:35, and Moon blink colour filters still gave a
