CED brightness measurement gave the same brightness as Censorinus
crater. The Cameron 2006 catalog ID=321 and the weight=4. The ALPO/BAA
weight=2.
In 1962 Sep 09 at UT 01:42-02:00 Bartlett (Baltimore, MD, USA, 5"
reflector, x180, S=5-4, T=3) observed in Agrippa the shadow of the
central peak to be grayish, not much darker than the floor, estimated
at 3deg bright, whereas on 1962 Jul 12, at col 28deg, in the 5"
telescope the dhadow was anormal black and sharply defined against the
floor which was 3 deg bright. The Cameron 1978 catalog ID=768 and the

shaped and fanned out across the floor. Could see hint of knot
seen before. Craters named in 7/23/88 (#319) were all normal
this time too". Is it possible that this report refers to the
crater "Gray" rather than "Proclus" as the column field suggests
in the Cameron catalog? The Cameron 1978 catalog ID=333 and
weight=5. The ALPO/BAA catalog weight=2.
On 1981 Sep 08 at UT 21:28-21:34 P. Madej (Huddersfield, UK, seeing

refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not
visible, however Heraclides E, Helicon G, and indeed many other smaller
craters could be seen. There were two small mountains in the general

Caruso states that Bianchini G should normally be much more clearly
seen than the other features mentioned and is the same size as
Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3. The
ALPO/BAA weight=3.
On 1988 Jul 25 at UT03:15 H. Davis (Madison, WI, USA) stated that

On 1955 Jan 05 at 01:00-01:30 UT D.A. Logue (Larchment, PA, USA, 15cm
reflector at x340, seeing Good) saw a strange blue light above the
surface of the Moon where the night and the day meet. He observed this
light for more than 30 min and it did not appear to move. It appeared
like a star in that the rays of light came from it. The observer adds
that he first thought thst the objects was a star, but later decided
that it had to be on the Moon itself. A drawing shows the blue spot
near the rugged south east limb of the Moon. The editor of the
Strolling Astronomer (Vol 8, No. 11-12, Nov-Dec 1954, p146) was unable
to identify the craters drawn. The editor speculates that the observer
saw a high mountain peak with its summit in sunlight and detached from
the illuminated regions - however this would not explain the blue
colour. Note this is an ALPO observation and does not apear in the
Cameron catalogs. ALPO/BAA weight=2.
On 1963 Nov 28 at UT 00:30-01:45 Greenacre, Barr, Hall and
Dungan (Flagstaff, AZ, USA, 24" refractor and 69" reflector),

On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK,
12" reflector, x200, seeing=II) noticed in the area south east of
Manilius that it was brighter in red light than in blue light at
20:15UT whereas 1 minute later it was the same brightness in each
filter. The effect reappeared at 20:21UT and was particularly strong at
20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was
of high reflectivity in white light and was bright in red at 21:15UT,
thougjh the south east area stopped giving a colour reaction at
21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT
however at 23:55UT it was surrounded by a transient white ring that
varied in visibility in an irregular way. Foley found Manilius B had a
vivid blue interior and in blue light the ring was black. and not at
all seen in red or white light. The CED brightness measurement varied
from 1.9 to 2.4. All other regions observed were normal in brightness.
Violet was seen on the west wall of Aristarchus though. M.Price
(Camberley, UK) found a possible blink in Manilius B but was observing
under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5.
ALPO/BAA weight=4.

Aristarchus 1982 Nov 27 UT 20:13-01:00 J-H Robinson (Teighmouth, Devon,
UK) found that the bands of Aristarchus were clearer in red than in
blue light. North found that the sunlit part of the crater was very
bright. M. Cook described the crater as a "kaleidoscope of colour.
Foley observed UT 23:05-01:00 (Kent, UK, Antionadi III, Transparency

cloud in Mersenius.
On 1997 Oct 13 at UT11:09-11:21 D. Rodway (Oamaru, South Island, New
Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in
the south east corner interior of the crater Aristarchus. This colour
was confirmed by the observers wife. By 11:21 UT the colour had faded
completely. Rodway had been a lunar observer since 1958, using a wide
range of instruments from 3 inch refractors to 12 inch reflectors and
had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so
was an experienced observer. The ALPO/BAA weight=4.
On 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector,
seeing III-IV) found that LaPlace A was significantly more prominent
than usual - comparisons were made with photographs in books. The
Cameron 2006 catalog ID=178 and weight=3. The ALPO/BAA weight=1.
On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit
around the Moon, obtained images of the Cobra Head region of
Aristarchus crater that suggested a ~15x colour ration increase (0.4
microns / 1.0 microns) in comparison with images obtained on 1994 Mar
03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting.
However it was later suggested that this was due to incorrect
radimetric calibration procedures being followed. The ALPO/BAA

around the northern edge of the lava sheet. Hill believes that it may
have been the same effect as seen by Madler (Germany), Barcroft (USA)

transparency, good) noticed in Aristarchus, blue to the north west
(IAU?) internal wall, also blue observed in other small bright objects
against dark backgrounds. Lunar rotational axis and optical normal
related such that the normal runs NW-SE (IAU?) through these features.
Observer deduced that the coliur was obviously spurious and no blink

Messier 1981 Feb 10 UT 19:20-20:10 TLP discoevered by Hedley
Robinson (Devon, England) "Messier was brighter than Aristarchus
in both red and blue filters and also appeared indistinct, later
becoming invisible - lost in a bright streak. In comparison
Aristarchus was clear. Another observer, Amery confirmed that
Aristarchus was sharp in appearance but Messier certainly was not.
Cook likewiese found Messier not to be as sharp as Messier A due
to a big shadow in Messier A. Pedler found that the sun facing
wall of Messier was OK but that the shadow was changing from black
to grey periodically at intervals of 2-3 minutes to a few seconds.
By contrast he found that Messier A remained quite well defined.
He tried red and blue filters but found no blink effect. At 20:23UT
Pedler found that the shadow had stabilized to a shade of
"mid grey" although remaining ill-defined. North also found that
Messier A was distinct but Messier itself was ill-defined. Moore found
the same thing but thinks that this is normal for Messier under
this illumination to appear indistinct. More also saw the grey
interior shadow. Price saw similar appearance to Moore and suspected
that this was normal for this stage in illumination. Ratcliffe
suspected everything normal - just commenting that Messier was smaller
and no detail in comparison to Messier A. Madej and Taylor provided
a sketch that showed again a grey interior and merging with the east
wall/mare. Foley found Messier's pale grey interior to be un-focusable
but in comparison Messier A was sharp. He says that he would expect
a grey interior and the east wall to merge with the mare. However
the complete loss of deatil and variability were not normal. Cameron
comments that the Kuiper atlas confirms the fuzzy indistinct appearance
of Messier and that a Lunar Orbiter picture shows a grey shadow.
The Cameron extended catalog weight=5. The ALPO/BAA weight=3.
On 1992 Dec 30 at UT 17:36 A. Dollfus (Meudon, France, 1m aperture
telescope used) detected evidence for a dust cloud using CCD
polarimetry. The ALPO/BAA weight=5.
SE of Ross D 1967 Oct 10 UTC 02:15 Observers: Harris (Tucson, AZ?)
Corralitos Obs (Organ Pass, NM, USA, 24" reflector) "Bright area moved
80km/hr towards SSE & expanded as contrast reduced. Corralitos MB did
not confirm" NASA catalog weight=3 (average). NASA catalog ID #1049.
On 1981 Feb 10 at UT21:46-21:49 P. Madej (Huddersfield, UK) found a 2nd
mag star-like point on the north east wall of Aristarchus crater. M.
Price (Camberley, UK) at 21:46 and 21:49. North (UK) detected flashes
from the central peak. Foley saw Aristarchus as a "translucent glow".
Moore, Pedler and Ratcliff could not find Aristarchus. Earlier though
Amery (Reading, UK) had found Aristarchus to be sharply defined.
Cameron 2006 catalog ID=122 and weight=5. ALPO/BAA weight=3.
Limb North? 1881 Jul 04 UT 00:30 Observed by Several observers
(Lebanon, CT, USA, naked eye, alt @ 10 deg) "2 pyramidal protruberances
on upper limb (dark?). Points were darker than rest of moon's face then
slowly faded away (atm ? moon very low)" NASA catalog weight=? NASA
catalog ID #223.
On 1982 Dec 22 at UT 19:20-20:10 J-H Robinson (Teighmouth, Devon, UK,
10" reflector, x150, seeing=IV-V) could not distinguish between Messier
and Messier A. The tail of these features was very bright - two
telescopes were used. Moore (Selsey, UK, 12" reflector, seeing=III)
could see Messier A but found Messier itself obscured - just see the
west wall and thought that the comet like tail was unusual as it did
not appear divided. The Cameron 2006 catalog ID=192 and weight=5. The
ALPO/BAA weight=3.
On 1888 Jul 16 at UT 05:35? Holden, at Lick observatory, CA, USA
saw a "Lunar Volcano, 1st magnitude star on the dark side.
Yellow light tinged with red from refractor's secondary spectrum
(facet glint? or peak catching sun before others? Hunt saw
similar phenomenon in 1863." Corliss states that it was later
revealed to be a mountain ridge near the southern termination of
the Alpes. Cameron 1978 catalog ID=357 and weight=1. ALPO/BAA
weight=1.
Torricelli area 2003 Nov 01 UT 17:45-19:59 Observed by M. Cook
(Mundesley, UK, 90mm Quastar Catadioptric x80, Seeing III, Transparency
Very Poor) and A. Cook (Long Eaton, UK, 20cm Newtonian + CCD camera +
3x Barlow). "At 17:45 UT M. Cook noticed an extremely dark, dense,
circular area with a ghost type crater surrounding it. It lay in the
Mare Tranquillitatis - not easy to identify the region. A. Cook
observed with a CCD camera (seeing V) and commented that: as the
feature concerned was probably Torricelli and that as the sun was 29
deg above the horizon at this crater, it seemed strange that most of
the floor appeared dark (perhaps in shadow?), although this could be
due to small scale steep topography making the area look dark from lots
of local shadow. Other nearby craters did not appear to have such dark
shadows." Note it is possible that this may have been the shadow of the
west rim of Torricelli casting a shadow? BAA Lunar Section observation.
ALPO/BAA weight=1.

On 1987 Oct 03 at UT 01:0?0-02:00 R. Manske (Brooklyn, WI, USA, 8"
reflector, x226) observed sunlight glinting of the walls in spectacular
display of colours. White (even gold) was seen at the centre, and blue
