A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and
definition fairly good. Observer noticed that the Mare seemed covered
with a close network of innumerable streaks, and spotted with countless
numbers of light specks, so that it would hardly be possible to
delineate them all in one night. The spots and streaks together must
have numbered ~1000. The observer had never seen anything like the
number of spots and streaks. Peirce A, was not at all easy to se and
neighboring spots almost as bright made it difficult to distinguish
which one was Peirce A. ALPO/BAA weight=3.
On 1982 Aug 01 at 00:00-01:00 K. Marshall (Medellin, Columbia, 12"
reflector, seeing I-II) noted shading on the east floor of Plato that
was apparently lighter than the rest of the floor and this was seen at
both low and high magnifications. Foley notes that this was unusual.
There were three craterlets visible on the floor - the central one was
the brightest. Cameron 1978 catalog ID=178 and weight=3. ALPO/BAA

On 1976 Apr 10 at 21:15-21:49UT S.Spencer (60mm refractor x60, seeing
quite good) noticed a faint red glow at the south west wall of Gassendi
covering a span of about 35 deg arc. The observer had some doubts about
this because they were using a small telescope, but thought that they
ought to report it, just in case. A BAA Lunar Section report. ALPO/BAA

Plato 1966 Sep 25 UT 23:12-23:35 Observed by Moseley (Armagh, Nortern
Ireland, 10" refractor, x140) "Eng. moon blink sys. blinks inside the

On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector)
and at the same time Doherty (Sussex, UK, 15" reflector) observed a
strangely bright and pink/red north rim of Aristarchus crater during
UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT.
M.C. Cook (Frimley, UK) found the northern wall to have a red/purple
colour but the effect vanished after 50 minutes. Cook also saw a "V"-
like notch in the NW crater shadow and this appeared to be bigger than
normal. G. North (Sussex, UK) saw a tinge of pink colour on the
northern rim and a bit later a "ruby red" colour on the worth-west wall
- again this effect lasted 50 minutes. Moseley verified the colour.
Finally M. Hather (Yorkshire, UK) suspected the north wall of
Aristarchus to be blue in colour. Cameron suspects that this TLP is not
spurious colour because it is in the wrong place. The Cameron 2006
catalog ID=276 and the weight=5. The ALPO/BAA weight=4.

before 20:54 UT) brightness variance in Torricelli B. J.D. Cook
(Frimley, UK) observed a brief blue coloured patch somewhere in the
Torricelli B region, but could not pin it down precisely. At 22:50UT
M.C. Cook (Frimley, UK, 30cm reflector, seeing III - occasionally V,
transparency moderate to good) Found the crater to have an elongated
appearance (in SSW-NNE direction) in white light, similar to the
previous night. A bright elongated spot was seen on the NNE floor,
close to where the wall should be. Not able to define the rim. There
was a very dark surrounding area to the crater, similar to what it was
on the previous night (roughly 1/4 brightness of Censorinus). 23:04UT
brighter in yellow, then red, then blue. At 23:10 it was seen that blue
filter dulled the crater - this was odd because both Censorinus and
Proclus were brighter in blue, which is what he would normally expect.
At23:15 UT Censorinus was brighter in blue, then yellow then red
filters and some orange spurious colour seen to the south of
Censorinus. At 23:23UT no spurious colour seen on Proclus or

On 2010 Dec 09 at UT 17:00 A. Heath (Long Eaton, UK) whilst
observing the Earthsine with 10x50 binoucluars, noticed some
coloured bands on the night side. The NW sector of Eartshine,
closest the limb was a normal dull brown, there was a whitish
fringe on this going from the N to the SE, followed by a thicker
bluish fringe. The rest of the Earthshine beyond, until reaching
the illuminated crescent was black. The two coloured fringes
curved slightly. Local temperature 38F and some broken cloud
present. Thickening cloud prevented further observations. The
observer suspects that it could have been caused by the weather
conditions, but could also have been due to a cataract starting
to form in his observing eye. This is unlikely to be a TLP due
to the above observer suggested reasons, and anyway it would
have to have been an unbelievably large phenomena to cover such
a large part of the Moon. However it is worth checking to see if
anybody else was observing at the time. ALPO/BAA weight=0.

telescope, x80-x130, atmosphere hazey - poor transparency) noticed that
the east side rims were slightly fuzzy and suspects that this might
have been due to the illumination angle. A.C. Cook (Frimley, UK)
obtained some CCD images that revealed that the effect was to some

the weight=5. The ALPO/BAA weight=2.
Mobberley and Foley note that Aristarchus was very
prominent in Earhshine. Little other detail seen
in Earthshine other than the limb. The Cameron
2006 extension catalog then says: "Confirm moving
side to side. Saw bright blue spot in center" however
it is unclear whether this refers to Aristarchus,
or Torricelli-B - the latter was also undergoing a TLP
at this time. Cameron 2006 extension catalog ID=267
and weight=5 (confirmed?).
On 1985 Apr 27 UT 22:00 M. Mobberley (Suffolk, UK) could not see much

On 1981 Aug 09 at UT05:08-05:21 D. Louderback (South Bend, WA, USA, 3"
refractor) found that the bright patch in the southern part of Eimmart,
could only be seen well in red light (this is between A, C and D in his
feature notation) i.e. 5 brightness values higher than in white or blue
light. Indeed in white light this bright area was closer to the east
wall bright spot. The Cameron 2006 catalog ID=149 and weight=4. The
ALPO/BAA weight=2.
Proclus 1971 Aug 30 UTC 00:34 Observed by Bartlett (Baltimore, MD, USA,
5" reflector x79-283, S=7, T=3) "C.p. very dull, grayish, 4 deg albedo.
Floor much darker=3.5 deg, still showing olive tint." NASA catalog
weight=3 (average). NASA catalog ID #1308.
On 2001 Jun 29 at UT22:16-22:22 C. Brook (Plymouth, UK, 60mm refractor,
x120, no spurious colour seen, seeing I) observed that the central
peaks of Alphonsus looked bright at 22:16UT but had dimmed by 22:22UT.
the three dark patches on the floor of Alphonsus were clearly seen. The
ALPO/BAA weight=1.
1996 Apr 27 UTC 02:26-03:14 Observed by Spellman (Los Angeles, CA, USA)
" 0232:26 U.T. Sunrise on Tycho 3/4 of the crater was in shadow,
topmost section of the central peak was in sunlight. In white light
brightness of the central peak rivaled the brightness of the Eastern
(sunlit) wall. No change was detected in red light, however in blue
light definite strong darkening was observed. Blink obtained when
viewing thru 25A and 38 filters. At 2:52 U.T. in the poor to fair
seeing the apparent size of the central peak in white and red light was
the same, in blue light the central peak in white and red light was the
same, in blue light the central peak size shrank to 1/2 white and red
size (and brightness). Also appearing sharper. Comparison was made also
with the central peak of Alphonsus, no changes were observed. The
significant part of the observation was the relative brightness of the
central peak to the sunlit rim in white and red light, they appeared
almost identical with the crater rim, being just slightly brighter. In
blue light the brightness of the central peak was reduced by at least
half while the rim brightness was not, (relative to one another). I
strongly believe that this was a real event. The shadow filled
portion of Tycho was examined for any abnormalities but none
were observed. Observations were ended shortly after 3:14 U.T. due to
clouds. I also conducted about 20 Moon blink observations during this
observing run and got the same strong reaction each time." ALPO/BAA
weight=3.
On 1994 Apr 19 at UT 22:00 R. Knopp (Berlin, Germany) noticed a
darkening of the interior of the crater Atlas. The ALPO/BAA weight=1.
Remarkable bright spot seen. Cameron 1978 catalog ID=134 and
weight=3. ALPO/BAA weight=2.
East of Picard 1864 May 15-16 UT 23:00-01:00? Observed by Ingall
(Camberwell, England?) "Remarkable bright spot" NASA catalog weight=3
(average). NASA catalog ID #134. ALPO/BAA weight=3.
On 1982 Jul 01 at UT 02:23-02:58 Robotham (Springfield, ON, Canada,
seeing=II) found that the west rim of Pytheas crater was a very bright
yellow-white, indeed brighter than Proclus. At lower magnifications,
Pytheas was one of the brightest spots on the Moon. The Cameron 2006
catalog ID=173 and weight=2. ALPO/BAA weight=2.
Plato 1937 Dec 12 UT 16:45-21:00 Observed by Barker (Chestnut,
England, 12.5" reflector x420) and Fox (Newark, England, 6.5"
reflector, 24?x) "Strong streak of orange-brown on E.wall. Floor
nearly clear of shad. composed of many veins & thin streaks
interwoven. At 21h irreg. extension seen spreading eastward down
wall. Confirmed by Barker's younger son. NASA catalog weight=5
(very high). ALPO/BAA weight=4. NASA catalog ID #428.
Peirce A 1927 Dec 03 UT 22:00 Observed by Wilkins (England, 15"
reflector) "Invisible (date in MBM) is wrong, would be only 6h before
NM. Sunrise on crater is at 3d & ? h. No interposition of dates works
e.g. 13th or 1926 or Dec 26 1923. Only Dec 3 1927 is feasible as it
would be just after 1st Q. & more similar to the May obs.)" NASA
catalog weight=4? (high). NASA catalog ID #396.
On 1988 Mar 27/28 UT23:30-00:30 M.C. Cook (Frimley, UK, 12" reflector)
found Censorinus to have a "foggy/fuzzy" appearance that was not seen
in adacent areas. The Cameron 2006 catalog ID=321 and weight=4.
ALPO/BAA weight=2.
On 1988 Mar 27/28 at UT 23:30-00:30? M.C. Cook (Frimley, UK, 12"
reflector) noted that the crater Proclus was bright visibly, but the
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.
On 1968 Oct 01 at UT 21:00? Bartlett (Baltimore, MD, USA) and Beck
(Ohio, USA, x437) observed lack of detail on the floor of Plato,
however the wall of the crater was easily resolved. Cameron says that
this was an independent confirmation. The Cameron 1978 catalog ID=1092
and weight=5. The ALPO/BAA weight=3.
Ross D 1965 Dec 04 UT 04:25 Observed by Cross (Whittier, CA, USA, 19?"
reflector) "Obscuration of part of the rim, also bright area 7-10km
diam. Not seen on following nite." NASA catalog weight=4 (good). NASA
catalog ID #917.

(England?) "Bright Point" NASA catalog weight=2 (low). NASA catalog ID
719.
Plato and Plato A 1972 Jan 26 UT 18:25-18:55 Observed by Watkons and
Hunt (England, 4.5" reflector x150, x225, and a 2.75" refractor) "Misty
patch over A, & a misty brightness over SW wall of Plato. Hunt saw
nothing unusual." NASA catalog weight=2 (low). NASA catalog ID #1321.
On 1980 Aug 21 at UT20:00 J.H. Robinson (Teighmouth, Devon, UK)
detected colour, using a Moon Blink device, and "mistiness" on the
southern floor of Tycho crater. The seeing was poor! Cameron 2006
catalog ID=104 and weight=1. ALPO/BAA weight=1.
Proclus 1958 Sep 24 UTC 02:46-03:02 Observed by Bartlett (Baltimore,
MD, USA, 5" refletor x180) "Proc. C remarkably dull, 4deg,
grayis. Appear. does not conform to any comp. col. The ray (ridge?
connecting to the c.p. was also grayish & 4deg as was the c.p.
Suggestion is strong that a common factor affected all 3." Nore Proc. C
is probably not Proclus C crater but a spot inside or in the vicinity
of Proclus from Bartlett's own notation. NASA catalog weight=4 (high).
NASA catalog ID #698.
