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 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

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

On 1975 Apr 23 at UT 20:30 J-H Robinson (Teighmouth, Devon, UK, 260mm
reflector, x200). Observer was observing since 20:30UT, at 21:00UT
though they noticed red on the outside south wall of Aristarchus, a
hazy ill defined area that was larger in a red filter than in blue
filter, and outside east wall was bright in red. At 21:08UT the outside
west wall of Aristarchus no longer gave a colour blink reaction, and at
21:22UT the colour blink on the southern end of the crater ceased, but
the image blur remained (in both red and blue filters) despite the rest
of the crater being sharp in detail. Observations ceased at UT 21:35
because the blurring at the southern end seemed to be normal and this
was confirmed when checked with photographic atlases. Other craters
such as Proclus, Pickering, Tycho, Gassendi, Copernicus, Alphonsus,
Plato, Menelaus, Manilius, Linne and Theophilus, showed no colour blink
reactions. However Picard had a red bright blink from 20:30-20:40 and
the permanant blink on the N. Floor of Fracastorius was detectable.
Also Plato floor shadings were clearer in red than in blue -
intermittently. This is a BAA lunar section observation. No estimation
of transparency or seeing is given, nor any comment on whether spurious
colour was seen in any craters visually. ALPO/BAA weight=1.

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

observation made in 1987. Darling believes that these are ridges.
Cameron comments that in LO-IV 192-3,2 a ridge is revealed on the
inside wall that matches the description. Cameron 2006 catalog ID=66
and weight=2. ALPO/BAA weight=1.
On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"?
reflector, seeing III) found that Aristarchus was very bright and
slightly blue. Cameron comments that Moore's eyesight is not very blue
sensitive. The Cameron 2006 catalog ID=175 and weight=4. The ALPO/BAA
weight=2.
On 1982 Jul 09 at UT01:05-01:25 P. Moore (Selsey, UK, 12.5" reflector,

On 1989 Aug 20 at UT13:55 M. Lucas (Melbourne, Australia, naked eye)
witnessed a "pin-point flash" in the middle of the lower right quadrant
of the Full Moon. Foley suspects that this was in the Proclus region?
The Cameron 2006 catalog ID=374 and the weight=2. The ALPO/BAA
weight=2.
1964 Jul 28 Aristarchus UTC 04:30-04:57 Observed by Bartlett

pale viol. on VA." NASA catalog weight=4 (high). NASA catalog ID #867.
On 1991 Dec 28 at UT 02:10 P. Moore (Selsey, UK) could see no detail on
the floor of Plato crater. This report needs to be read in context with
the comments by Cameron for A.C. Cook's observation of the floor of
Plato on 1992 Jan 18 - Cameron 2006 catalog ID=438.
On 1916 Jan 27 at 22:00? Markov (Russia) noticed that a light sector
was visible at the bottom of Plato, in shadow, and contained 3 bright
spots, reminiscent of phfescent bodies. The Cmaeron 1978 catalog ID=362
and weight=3. The ALPO/BAA weight=3.
On 1979 Sep 16 at UT 08:00-09:00 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x62-x97, clear, but Moon at low altitude) detected
four new features that he had not seen before in Earthsine in
comparison with what he saw on 16 Jul 1979, this time in the southern
part of the Moon. pin-point flashes were seen within these bluish
areas. Each time a flash occurred the gas clouds brightened (sometimes
by 6x) for a few seconds. Cameron thinks that these are related to
moving clouds on the Earth's limb e.g. mackeral sky. Cameron 2006
catalog ID=69 and weight=1. ALPO/BAA weight=1.
On 1824 Jan 27 at UT03:00 Gobel (Koburg, Germany) observed a reddish
colour in Aristarchus crater. The Cameron 1978 catalog ID=98 and the
weight=4. The ALPO/BAA weight=3.
In 1936 Jun 22 at UT 05:00 Roth, Weldy (Alliance, OH, Oak Park, IL,
USA, 10" refractor, 6" reflector) observed in the Southern part of mare
Crisium (60E, 10N) "Both noted reddish spots nr. S. end of mare, (Martz
could not confirm, moon had set for him)". The Cameron 1978 catalog ID=
415 and weight=4. The ALPO/BAA weight=3.
On 1971 Feb 27 at UT 23:50-00:00 Dezmelyk (Newtown Square,
Pennsylvania, 2" refractor, x225, x500, seeing=good) observed in
Earthshine a peculiar white glow too far from the terminator to be
sunlit. 9 minutes later they could not detect this, nor any other
spots. The spot concerned was about 8-9th magnitude - "like galaxies".
They checked the lens for dirt but it was clean. A drawing was
provided. The Cameron 1978 catalog ID=1285 and weight=2. The ALPO/BAA
weight=2.
On 1985 Apr 23 at UT20:00 Smith (England, UK) found two large glows in
Earthshine, one was somewhere in the vicinity of Gruithuisen (i.e.
between Aristarchus and Sinus Iridum). The Cameron 2006 catalog ID=263
and weight=1. The ALPO/BAA weight=2.
On 1985 Apr 23 at UT20:00 Smith (England, UK) found two large glows in
Earthshine, one was west of Bullialdus crater. The Cameron 2006 catalog
ID=263 and weight=1. The ALPO/BAA weight=2.
On 1991 Jan 19 at UT10:25 P. Jean (Outremont, Canada) noted that
there was a red glow on the north west limb near Carpenter,
lasting just a few seconds. The Cameron 2006 catalog ID=418 and
the weight=0. The ALPO/BAA weight=1.
On 1989 Feb 09 at UT 19:00 Ashton (Stafford, UK, seeing=V) observed a
"green glow in the "peninsular region" of Cape La Place (south of poss.
Helicon A?) and brown on the Earthlit limb. Foley (Kent, UK, 12"
reflector) noticed a "pin point glow surrounded by blue-green halo"
through a blue filter, but not seen through a red filter. He also
suspected some brightness variations. He noted that Aristarchus was
barely seen and Copernicus was only a faint smudge, presumably because
of the bright limb? J. Cook (Frimley, UK) observed a white glow in the
Cape region (made up of pin points?) - no other places had a similar
effect. P. Moore (Selsey, UK, 12" reflector) reported that nothing
unsual was to be seen anywhere on the Moon. M. Cook (Frimley, UK) found
a "bright point source near the tip of LaPlace perhaps maupertius D (or
LaPlace D?)." This was seen in a blue filter but not through a red
filter - the limb was also seen as bright and the cape as a faint
patch. Holmes (Lancashire, UK, 30"? reflector or refractor?) although
commenting that Aristarchus was a bit dull, could not see the Sinus
Iridum glow, North (UK) could only detect the vague presence of
Earthshine throug his finder scope, but not in his telecope. The
Cameron 2006 catalog ID=349 and the weight=2. The ALPO/BAA weight=3.
On 1989 Feb 10 at UT 19:00? D. Holmes and Wooler (Lancashire, UK) found
Aristarchus to be bright, but so too was an area near crater. The
Cameron 2006 catalog ID=350 and weight=3. The ALPO/BAA weight=1.
On 1989 Feb 10 at UT 19:00? D. Holmes and Wooler (Lancashire, UK) found
area near Prinz to be bright, but so too was Aristarchus crater. The
Cameron 2006 catalog ID=350 and weight=3. The ALPO/BAA weight=1.
On 1989 Feb 10 at UT 19:00? Edmonds (England) observed a "bright red
coppery" colour in the northwestern part of Proclus crater. He checked
and found that there was no colour elsewhere, though he still suspects
that the effect was spurious colour. Cameron comments that usually blue
is seen in the north and red in the south if due to spurious colour.
The Cameron 2006 catalog ID=350 and the weight=3. The ALPO/BAA
weight=2.
On 1988 Mar 23 at UT 01:15-01:30 M. Wisniewski (Chicago, IL, USA, S=F)
observed that Aristarchus was the brightest (mag 5), and only feature
visible in Earthshine. It had the appearance of a steady blue-white
star like point. Darling (Sun Praire, WI, USA) though observed other
features as well: Proclus, Theophilus, Cyrillus and Censorinus - all of
which were normal. The cameron 2006 catalog ID=319 and the weight=0.
The ALPO/BAA weight-1.
Posidonius 1968 Apr 03/04 UTC 22:29-00:15 Observed by McConnell
(Antrim, N.Ireland, 3.5" refractor, x117, S=E) "Peculiar haziness in NE
(ast. ?) corner of crater. Greenish-yellow tint similar to M.Crisium at
FM. Central crater was clearly vis. N.wall showed no detail at all."
NASA catalog weight=3 (average). NASA catalog ID #1064.
Proclus 1983 Jan 19 UT 20:36-21:00 Observed by Cook (Frimley, UK,
Seeing III, Transparency, Moderate) "Colouration seen". BAA Lunar
Section Report. ALPO/BAA weight=2.
On 1985 Apr 25 at UT 21:34-22:04 H. Miles (England) observed
Aristarchus within Earthshine. Foley (Kent, UK, 12" reflector) had
observed it one hour prior to Miles and found it to be both dull and
blue - with a bright patch west of the crater on Aristarchus Upsilon
Mountain. At 21:45UT 6 star-like flashes seen on the floor. They
occurred again a few minutes later and repeated at 22:04UT.By 21:45UT
the bright patch had gone though. Smith (England) had also apparently
seen the flashes and a further glow, albeit more north of the one seen
by Foley. Miles confirmed Smith's glow north of Aristarchus. The
Cameron 2006 catalog ID=264 and the weight=3. The ALPO/BAA weight=2.
Curious lack of detail, but this may have been related to
the seeing. Of greater interest though was a dark blue
splodge where the crater should have been. Shadow seen through
this splodge, but no crater rim seen.
Almost certainly the following was spurious colour and not
a TLP. Proclus was found to be brighter than Censorinus.
Red was seen on the northern inner floor and blue on the
edge of the external north rim NNE-NW. The rim to the SW
could not be seen. ALPO/BAA weight=1.
A German observer by the pseudonym of "R" on 1883 Nov 05 UT 18:00 saw
Aristarchus as a vry bright 7-8th magnitude star in the dark part of
the Moon. The Cameron 1978 catalog assigns this event an ID of 240 and
a weight of 3. The ALPO/BAA weight is 1.
On 2001 Jun 26 at UT 22:16-22:20 C. Brook (Plymouth, UK, seeing
conditions very good, x120) reported that the central peak of Alphonsus
was brighter than the central peak of Arzachel (or was it the other way
around?). Cook observed 4 hours later from Washington DC, USA and found
that on CCD images that the central peak of Alphonsus was only slightly
less than that of Arzachel. The ALPO/BAA weight=2.
Aristarchus appeared to glow in Earthshine with a faint
green luminescence that moved from side to side. A bright
blue central spot was also seen. The green colour was detected
in two seperate eyepieces. Observation made from England.
Cameron 2006 catalog extension ID=266 and weight=2.

G Johnson of Swanton, MD, USA used a 2" refractor at f/12.
Aristachus revealed as a red spot on a photo of the Moon. This
was similar to another photo obtained on 1988 Apr 21st. Frame (with 3
exposures present)reveals a dim star like point near Campanus on
exposure 1. Expsoure 2 shows it a little east on the Earth-lit
part. Exposure 3 shows it off the south-east limb. Apparently 20
minutes later took 2 exposures and frame 18 was a double. The
second exposure revealed an object farther from the limb but the
first exposure does not show the object. The two high power exposures
do not show it. Cameron could not see the spots that Johson describes
on his slides, but did see several spots (defects?) on the
8 and 12 second exposures near Hevelius and also on the 20 second
exposure near to Hecataeus only. BAA members observed star like
flashes a few hours earlier - near Aristarchus. One BAA member, Madej,
had seen a green glow in Arisarchus in two places in two eyepieces.

"Eudoxus" 1877 Feb 20 UTC 21:30-22:30 Observed by Trouvelot (Meudon,
France, 13" refractor?) "Fine line of light like a luminous cable,
drawn W. to E. across crater". NASA catalog weight=1 (very low). NASA
catalog ID #185. ALPO/BAA weight=1.
On 1993 May 28 at UT 21:02-21:30 M.C. Cook (Frimley, UK, 3.3" Questar
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
extent still there one hour later. The Cameron 2006 catalog ID=461 and
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
detail in Earthshine (apart from Aristarchus), except that there was a
brightness on the western limb of the Moon. The Cameron 2006 catalog
ID=267 and the weight=5. The ALPO/BAA weight=1.
On 1985 Oct 11 at UT 04:56-05:12 D. Louderback (South Bend, WA, USA,
4" refractor, x95, seeing=1-2-1 and transparency=4) detected a change
in brightness of Mons Piton point D (his designation) during 04:56-
04:59. The whole of the east slope was affected - initially bright and
then faded and there was a blue colour (detected with filters). The
variabilty was 8-11sec (Cameron suspects atmosphere as the altitude was
low). The brightness stabilized at 05:12UT, but variability resumed
until observing finished. As a comparison Aristillus was not seen to
change. The Cameron 2006 catalog ID=287 and the weight=1. The ALPO/BAA
weight=1.
On 1973 Dec 02 at UT 22:17:33 Barrett and Brick (New York, 3.5" Questar
freflector) observed an occultation of Kappa Aquari, a wide double
star, on the western limb. The star faded perceptably before
disappearing. Cameron says that the fact that the star was a double was
not an explanation - she says that there are many reports of similar
fades for single stars. The Cameron 1978 catalog ID=1384 and weight=4.
The ALPO/BAA weight=1.
On 1931 Mar 27 R.Barker (observing from Cheshunt, UK, 12.5" reflector)
found that the central mountain in the brilliant ray crater Tycho was a
curious shade of grey. This was despite the interior of Tycho being
fully in shadow. Cameron 1978 catalog ID=400 and weight=3. ALPO/BAA
weight=3.
Cusps 1941 Mar 07 UT 04:00? Observed by Barcroft (Madera, CA, USA, 6"
reflector) "Prolongation suspected. (date reported =6th, but if loc.
time =7th UT). In this case we have assumed the 7th" NASA catalog
weight=1 (very low) NASA catalog ID #485.

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.
Tycho 2003 May 10 UTC 03:15 Observer Robert Spellman (Los Angeles, USA)
- "CCD video of spur-like features coming off N & S edges of central
peak - spurs pointed eastwards". It is now thought that this effect is
almost certainly seeing flare as it is visible on other features in the
image, although to a much lesser extent. The ALPO/BAA weight=1.
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.
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.
Linne 1867 Mar 15 UT 20:00? Observed by Dawes (England?) "Excessively
minute black dot in middle of feature. A geom. fig. boarded & centered
with black that formed, dissolved & formed again" NASA catalog weight=3
(average). NASA catalog ID #150.
W. of Mare Humorum (50W, 25S) UTC 00:00? Observed by Mac Farline
(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.
Gassendi 1977 Sep 23 UTC 21:15 Observed by Cook (Frimley, England, 6"
reflector x144, Seeing IV (Antoniadi)) "Prominent red dot seen at
central peak, also a hint of red on floor in N. quadrant of crater.
More likely to be spurious colour than TLP the observer feels"
