On 1979 Aug 12 at UT07:00-10:35 D. Darling and wife (Sun Prarie, WI,
USA, 12.5" reflector, x342, photos, S=9/10) observed a cigar shaped
protruberance in Romer crater that cast a 32km long shadow, nestled in
a valley rille next to Romer. This was a confirmed observation. The
effect persisted intil sunset. The top of the object and two points on
the crater rim were reflecting the Sun's rays. "Top of obj. & 2 pts on
crater rim reflected suns rays. It was as high as the crater rim

On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK,
seeing=IV-V, transparency=good, spurious colour seen) found 2
bright pathces on the east rim on alternate sides of a bright region.
The band from the central 16km wide region was dark on the east side.
Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be
not as bright as normal, apart from the band that Mobberley found (1
hour later). The dark regions were a murky green colour (bright through
green, blue and yellow filters and dark through red and orange
filters). Cook (Frimley, UK, transparency=excellent, CCD camera used)
found a bright "bulge"on the eastern side. Apparently data suggests
that the band was brighter in red than in near IR light. Cook's
calibrated brightness measurements suggest that there was no change in
brightness over the crater with time. Two other bright points were
seen: one at the Cobra's Head and another half way between the east rim
of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87
(near IR) and combined Wratten 29 and Wratten 87 were used. In the red
Wratten 29 filter the brightness falls at22:20 at Shroters valley and
then rises in the bright ray. They return to normal at 22:30UT. There
was however a lot of measurement noise from the brightness readings of
points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The
ALPO/BAA weight=3.
F. Graham took some photos of the Cobras Head and found a blue cloud
about 50 km in diameter and scattering light - Cameron says that
this indicates high density. Darling found the Cobra's Head obscure and
variable "clear and bright to diffused". Cameron was alerted observed
(02:40UT) variations with periods of approximately 30 seconds, and
thought that she could see a red tinge on the east rim of Aristarchus -
checks elsewhere found no other colours. Darling found that a blue
filter enhanced the effect and a red filter made it disappear. There
was a blink at 02:55UT but no blink in the Cobra's Head, which looked
fuzzy and lacking in detail. The effect was confirmed by Weier, who
also saw two dark spots in the Cobra Head in blue but not in red light.
The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall
7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south
wall 7.0, East wall 8.0, and the central peak 10.0. Observer details
were as follows: Darling (Sun Praire, WI, USA, 12.5" reflector, x159,

Cobra Head 1955 Oct 31 UTC 19:00 Observed by Milligan (England?) "Dark
blue obscuration" NASA catalog weight=3 (average). NASA catalog ID 624.
Mobberley noticed that Torricelli B was bright and had an even brighter
spot on the inner north wall. The observation was made from UT19:45-
21:40 using visual and video techniques. There was also a bright region
NNE of Toricelli B, that was noticed. Foley examined the video and
found that the crater faded in brightness over time and also the bright
area to the NNE was not as bright on video as had been seen visually.
Foley speculates that because the CCD camera was sesnitive to the near
IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and
also saw the bright spot on the inner north wall - but saw a blue halo
around the crater. Response in blue filter, darkening over whole
region. Brightness measures with a crater extinction device (CED)
indicated that the crater was 80-85% the brightness of Censorinus.
There was a bright area NNE of the region. M. Cook observed 22:10-
22:16UT (15cm reflector and seeing III-IV) and also saw that the crater
was very bright indeed with a spot NNE of the region (same position as
28/28 1985 observation) - suspected that the crater might have been
brighter than Censorinus, but judgement effected by seeing. In a blue
filter the crater dulled leaving the bright spot prominent (but only
during a good moment of seeing) - therefore had some suspicion of
seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the
area, but the seeing was even worse - but did manage a check of the
brightness of Torricelli B to Censorinus and now made it one quarter of
that of Censorinus and no sign of the crater dimming in the blue as had
been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at
21:15UT (Dec 27) thought that Torricelli B looked normal and saw no
colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images
through red+IR (Wratten 25) and IR (Wratten 87) but found no colour
differences, though there was a very slight hint that a brightness fade
may have occurred between those two observing times. Note that this
report does not have an entry in the Cameron 2006 Extension Catalog.

that the central peak of Aristarchus was quite bright and extended to a
circular region in the east in the crater "sprout" area - Cameron
suggests that this is Bartletts self defined EWBS area?. Beyond the rim
to the east was very bright. However no colour effect was seen in

On 1985 Dec 29th at UT 23:23-23:58, M. Mobberley (Bury St. Edmunds,
Suffolk, UK, seeing II-III) made a video scan of the Moon. P.W. Foley
examined the tape and noted something that Mobberley had not seen
visually. Two scans of Totticelli B had taken place, one at 23:23 and
the other at 23:58UT. In the first a brilliant point appeared briefly,
on the western rim, positioned at 3o'clock. In the second video
sequence this brilliant spot was present continuously and wandered
along the rim. It was possible to monitor frequency of turbulence
present, this apparent movement did not ppear to conform, although
judgement here was extremelydifficult as the feature was at absolute
point of resolution, a little better than 0.5 mile. Also considered was
the implication of the equipment effect, this did not seem to fit
either as other nerby craters in the same configuration, 30% shadow

craters. Sun's elev. @ 6deg. Drawing (possibly a high peak on E.wall of
A casting a shadow?)" NASA catalog weight=1 (very low). NASA catalog ID
#1342.
On 1944 Mar 12 at UT 23:00 H.P. Wilkins (Kent, UK, 8.5" reflector)
observed that Plato appeared incomplete - the central crater had it's
north wall obscured. cameron comments that maybe this was due to the
low altitude of the Moon? The Cameron 1978 catalog ID=491 and
the weight=4. The ALPO/BAA weight=2.
In 1955 Oct 05 at UT 03:40-03:48 Bartlett (Baltimore, MD, USA, 5"
reflector, x180, S=6, T=5) observed in aristarchus an itenseley bright
blue-violet glare on EWBS, E, and NE wall. The Cameron 1978 catalog IF=
620 and weight=4. The ALPO/BAA weight=2.
Near Kepler 1966 Dec 31 UT 03:00? Observed by Petrova,
Pospergelis (Pulkova Observatory, Russia) "Special glow in this
area. Confirmed by photoelectric method (Petrova) & polarimetric
(Pospergelis?) almost simultaneously recorded by both" NASA
catalog weight=5. ALPO/BAA weight=4. NASA catalog ID #1007.
On 1989 Jan 26 at UT 03:45 De Groof (Belgium) noted a white few second
long flash from Copernicus crater. The Cameron 2006 catalog ID=347 and
weight=3. The ALPO/BAA weight=3.
C.Brook (Plymouth, UK) noticed that the east wall of this crater was
brighter than the walls of nearby craters. Cameron comments that Foley
says that this is normal and agrees. Cameron 2006 Catalog Extension ID=
433 and weight=1. ALPO/BAA weight=1.
On 1964 Feb 02 at UT08:30-09:40 G.Reneau and B.Crowe (2.4"
refractor, x90)observed Ross D to be double. This was during a
time when observers were looking for a Ranger crash plume. The
Cameron 1978 catalog ID=799 and weight=1. The ALPO/BAA weight=1.
Something resembling a cigar shaped shiny object seen
on S rim - hanging over a smaller crater. It looked like a bright
aluminum can in the sun & cast a shadow onto the rim. The length
was 8-10 miles long x 1 mile wide at the central point.
It appeared tapered to points at both ends. Observer studied it
for several hours. S term. ~60-70miles away. Apparently not related
to topog. Alt. 8deg. Cameron 2006 Extension catalog weight=3.
ALPO/BAA catalog weight=1.
Plinius 1937 Jul 27 UT 04:37 Observed by Haas (Alliance, OH,
12"? reflector) "E. end of c.p. varied in intensity at similar
lighting conditions. Intensity was low est on this nite, being
at I=5.0. Other nites were:
Date Time col. I
6/23/37 0600 84 8.5
7/20/37 0200 58 6.0
7/22/37 0300 78 6.5
9/22/37 0700 114 6.0

10/17/37 0100 59 8.5
10/21/37 0500 109 8.5
NASA catalog weight=4 (good) on this and the nights listed. NASA
catalog ID #422. ALPO/BAA weight=3.
Jansen 2013 Aug 26 UT 00:30-01:30 P. Grego (Cornwall, UK, 20cm
SCT, x200, seeing II, transparency good) observed a dark patch
just east of Jansen D. He had not seen this before. There maybe
a depression here hinted at in LOLA ndata. ALPO/BAA weight=1.
Fracastorius 2022 Apr 21 UT 01:35-02:12 A. Amorim (Brazil -
90mm f/10 refractor, 25 & 10mm eyepieces ) observed visually a
little bright spot near the centre of the otherwise completely
shadow filled crater. The bright spot was surrounded by a coma
effect. Clouds intervened but by 02:12 the spot was no longer
visible, just a thin patch of light close to the crater's
centre. Observations started when the Moon's altitude was 15
deg and ended when it was 23 deg above the horizon. ALPO/BAA
weight=1.
