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.
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 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

of Aristarchus and red haze on the west side. At 00:00UT details were
more clear and at 00:24UT Aristarchus and Herodotus, were seperated. At
00:34UT colours were gone. At 00:35UT blue was on Aristarchus and the
area was bright, but was black in a red filter. At 00:53UT the features
were clear and the colour gone and the brightness had decreased to 9.
Cameron comments that the colour was not due to temp. inversion because
of being dark in the red filter, implying a medium). The Cameron 1978

Aristarchus 1987 June 14 UT 04:43-08:00 Observed by Curtis, Jacobs, and
Manske (Yanna Research Station, Carl A. Fosmark Jr. Memorial
Observatory, Madison Astronomical Society, WI, USA, 17" f4.5 Dobsonian
and the 8" f10 SCT Celestron) "On the night 13/14 June 11:42 P.M. to
3:00 A.M. local time or 14 June 04:43 to 8:00 UT. Three people
witnessed this event and all three of them observed with three
different telescopes to rule out instrumental aberration. These three
pople were members of the Madison Astronomical. The three observers
involved are Keith Curtis, Tom Jacobs and Robert Manske. Keith Curtis
took detailed notes of the event as he observed it. The observations
were made at the Yanna Research Station, Carl A. Fosmark Jr.
Memorial Observatory of the Madison Astronomical Society following the
annual picnic. This is MAS dark sky site and is located near Brooklyn,
Wisconsin. As they were observing the night sky they saw the Moon
rising and noted a strong orange color due to atmospheric effects.
Approximately 1/2 hour after the Moon rise they decided to turn one of
the telescopes on it. It was at 04:43 UT, it was noted by Keith Curtis
that as the Moon rose it began to loose the horizon color effect and
return to its normal color, but he found that the red color was not
leaving the crater Aristarchus. At first they all thought this was an
atmospheric effect but decided it was a real event since they detected
a second crater (Euler) showing red color on its rim. Keith Curtis
said that the red color was very strong on the Western rim of
Aristarchus with a strong blue/green or aqua green on the Eastern rim.
Keith also reported that the glow opaque enough to prevent viewing of
the interior of crater Aristarchus. He said they observed until 3:00
A.M. daylight saving time or 8:00 UT. and the red glow was still
visible when they ended their observing session. Robert Manske
description of the event was that he saw two craters glowing a strong
red and blue giving it a rainbow effect. He said that the red glow was
so strong he was unable to see the craters underneath during the entire
observing session. Concerning the orientation of the red and blue was
on the crater he stated that he did not remember since he failed to
take any notes. Concerning whether there was any difference in
appearance when they observed it with the 17" f4.5 Dobsonian and the
8" f10 SCT Celestron. He said that he could not detect any difference
to the lunar formation or the color on it regardless of which telescope
he used. He did mention that as the Moon was rising it had the
appearance of one large Maria in the center of the disk. This illusion
disappeared as the Moon rose higher into the sky. When talking to Tom
Jacobs he said that he remembered that he did not see anything on the
Moon until 1/2 hour after Moon rise. He said that he remembered that
the entire Aristarchus region had a strong reddish or pinkish color.
All three witness all reported variations in the type of color they
were seeing. This would indicate that individuals color perception is a
major factor during a color event. Keith Curtis saw a very strong
coloration around the rim of the craters, where Robert Manske saw the
entire region covered by this red and blue coloration and he could not
see the interior of the craters underneath. Tom Jacobs reported that
the glow covered the entire crater but he could see the crater
underneath it. The Moon never achieved a height greater than 21 degrees
so it could be that what the observers saw was caused by the Earths
atmosphere. Further details can be found on the following web site:

On 1981 Oct 26 UT 20:44-21:14 M. Mobberley (Bury St Edmunds, UK,
14" Cassegrain, seeing III) noticed an ~100deg wide fan on the
floor of Theophius, radiating on the central peak upto the
surrounding base of the wall next to Cyrillus crater. This fan
had a hint of yellow/red. The observer did not consider this to
be abnormal - there was certainly no loss of focus here as far
as the observer was concerned, and no mention is made of this
effect in later observations that night. Plenty of spurious
colour was reported. The ALPO/BAA weight=1.
Aristarchus 1966 Aug 05 UT 05:22-05:38 Observed by Bartlett (Baltimore,

On 1989 Apr 26 at UT 10:22-10:44 D. Darling (Sun Praire, WI, USA, 3"
refractor, x36-x140) found that the eastern half of Plato crater was
dark - and he checked this using several eyepieces. moderate

On 1981 Oct 18 UT 22:14022:16 M.Mobberley (Bury St Edmunds, UK,
14" Cassegrain, seeing variable, transparency misty) found that
the central craterlet on the floor of Plato was not visible,
despite it being visible under similar colongitudes on other
nights. Might be due to observing conditions, but observer
suspicous. At 02:08 the observer comments that the central
craterlet was ellusive, and at 02:42, though it is uncertain
whether they regarded it as suspicous still at this stage?

On 1982 Aug 11 at UT03:30-04:15 Mobberley (Suffolk, UK) obtained a
photograph and made a sketch that revealed a needle-like shadow from
the west wall to near by the central craterlet - the latter was quite
clearly visible. What were not visible were the other four craterlets.

Tycho 1983Aug30 UT 00:15-00:18 R. Moseley (Coventry, UK, 6"
f/10 reflector, x60, transparency very good, seeing III,
improving with altitude) attention initially caught by the
impression of a rosy colouration along the NW crest and outer
wall. For perhaps 2-3 min this persisted - before fading
entirely. The observer felt that the cause may have been
psysiological - or short-lived spurious colour. However
interestingly nearby craters did not show the effect. A
sketch was made over a longer time span 00:15-00:40UT.
ALPO/BAA weight=1.
In 1919 Feb 21 at UT 22:00? an unknown English observer observed in
Lexell crater an intensely dark line going out from it. The Cameron

On 1981 Sep 20 at UT 08:00-09:40 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x342, seeing=excellent) detected the small crater on
its western rim But not on the eastern floor. This was odd because both
are equal in size, furthermore smaller craters could be seen and the
Moon was at a high altitude above the horizon, so seeing not a problem.

Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK,
10.25" reflector, x250, Wratten 44a and 25, seeing II) noted
that Aristarchus was surrounded by a dark area in the blue
filter. They did not regard this as a TLP at the time. However
because Aristarchus is surrounded by blue material in real life,
this should have been brighter? For this reason, despite the
observer regarding this as a negative TLP, an ALPO/BAA weight=1
has been applied.

Aristarchus and Cobra Head 1968 Jul 18 UT 00:50-01:30
Observed by Moseley & Corvan (Armagh, N.Ireland, 10"
refractor, x255) and by Moore (Selsey, England, 3" refractor,
x 120) "Distinct red glow & obscur. 1st at 0050 S. of C.H. &
same size. At 0052h saw color on S.wall of Aris. Both
persisted till 0100h then both (faded, then brightened, then
faded. Plato, Gassendi & Kepler checked with neg. results.
Obscured areas reached greatest extent at 0125h wgen it was
1/2 size of C.H. & SSE (ast. ?) of it. Moore was alerted to
it & saw it in blink, but not vis. at 0107-0220". NASA

On 1989 Jun 28 at UT 08:39-09:00 D. Darling (Sun Praire, WI, USA,
3" refractor, x36) discovered that at this time Mons La Hire was the
brightest feature on the Moon. LaPrice was also very bright. Cameron
quotes that Darling recorded that LaHire had a brightness of 7.0 and
LaPlace=7.5. Darling did not think that this was a TLP. The Cameron
2006 catalog ID=369 and weight=0. The ALPO/BAA weight=1.
On 1989 Jun 28 at UT 08:39--9:00 D. Darling (Sunpraire, WI, USA, 3"
refractor, x36) noted that promontorium LaPlace was very bright.
LaHire brigtness was 7.0 and LaPlace was 7.5. Darling suspects
that this was not a TLP because "as did not have mother-of-perl
appearance as seen on Piton at times"The Cameron 1978 catalog ID=369

Grimaldi 1971 Jun 18 UTC 02:12-02:31 Observed by Jorgensen
(Denmark, 36" refractor, 60, 200x, seeing good) "Dark reddish
spot in SW part of crater. At 60x. Became clearer at 200x &
seen in midwest also. At 0331h phenom. clearest in west, while
S. region had faded. Air turb. & dawn ended obs. at 0331h.
Seen best in yellow filter, well in red, invis. in green &
blue." NASA catalog weight=3. NASA catalog ID #1298. ALPO/BAA
weight=3.
Closest parts of the Moon at Saturn appearing from
occultation were dull and hazy. Was this an effect of
the lunar atmosphere or a high haze and halo around the Moon?
Cameron's 2006 catalog extension gives this an ID No. of 3
and a weight of 1. The ALPO/BAA catalog weight is also 1.

Reiner 1986 Jun 04 UT 09:15-09:33 Observed by Darling (Sun Praire, WI,
USA, 12.5" Newtonian x79, x40, x35, Seeing 6, sky clear and steady -
Moon 9deg above horizon). David Darling was out on the morning of 4
June observing the planet Mars. While studying Mars the crescent Moon
rose giving me a splendid view of the earthshine portion of the disk.
As the Moon rose higher into the sky he decided to turn the telescope
onto it to the earthshine region of the Moon. He made it a practice
to examine this region of the Moon to monitor for craters that appear
to glow under this light. While observing he became aware of a black
spot located in the sunlit portion of the Moon about 60 miles west of
the sunset terminator. At first he thought the black spot was a shadow
being cast by a large mountain or crater. When looking at his lunar
charts he could not locate any feature that would account for it. As he
continued to study the black spot he realized that it appeared darker
than any shadows on the Moon. It was at 4 June 1986 4:15 A.M. CDT or
9:15 U.T. when he first sighted the phenomena and it was at 4:25 A.M.
CDT or 9:25 U.T. that he realized he was seeing a lunar transient
phenomena event. It was at this time that he could start to see silvery
filaments or streaks in the black patch. Between 9:23 and 9:25 U.T. he
watched the black patch disappear. When the black spot had disappeared
he found that the location of the black spot was over the crater
Reiner. he estimated that during the L.T.P. event that area covered by
the black cloud was approximately 40 to 50 square miles. He also had
examined other formations on the Moon during this event and none were
exhibiting the same phenomena witnessed over the crater Reiner.
