On 1979 Oct 04 at UT21:05-23:40 P.W. Foley (Kent, UK, 12" reflector,
x360, seeing=II) detected colour in Aristarchus (and also in Bullialdus
- there was a TLP alert at this time for Bullialdus) but nowehere else
on the Moon. Aristarchus had a CED brightness value of 3.8 at 21:05

On 1985 Sep 28 UTC 20:54-23:52 P.W. Foley (Suffolk, UK) found (actually
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
Censorinus. 23:46UT Torricelli B elongated as before, but a very faint
ray might have been seen to the south west of the rim. This report is
not in the 2006 Cameron catalog. The ALPO/BAA weight=3.

showed a grey column cutting across the central floor of the
crater from the west and then bisecting the eastern rim. All
detail inside is completely invisble. Some (but not all) of the
other images showed a more blurred view of this feature. It's
possible that this was a seeing ripple effect, or just the

1994? The Cameron catalogue does actually mention a TIFF on Clementine
mission? The Cameron 2006 catalog ID=474 and the weight=3. I am
assuming that the year should be 1994 and not 1995? The ALPO/BAA
catalog weight=1 until we can find out what the correct date is?

On 1996 Feb 12 at UT 07:30-08:27 J.Sandel (Caycee, SC, USA)
noted a contrast effect inside Tycho at sunset. At 07:30UT there
was a slight, but definite illumination of small areas of the
crater floor west of the central; peak. Also seen by T. Ferrel
(Lawrenceville, GA, USA, SCT C8). This was oval in shape and
gray in colour - Ferrel noted some diffuseness. It brightened
over 30 minutes. At 08:11UT a definite brightness fade noted in
Tycho's central peak. The crater floor had increased
illumination of entire crater floor. ALPO/BAA weight=3.
On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52"
reflector) observed that central craterlet in Plato was
unusually bright and shows up as a bright white spot on his
sketch - though this might have been artistic license in his
sketch. His written notes refer to the unusual lack of a rim
(especially the northern part) to this craterlet.

the weight=1. The ALPO/BAA weight=1.
On 1903 Mar 03 at UT 20:00 Gheury (London, UK) observed a star-like
point in the dark side in Sharp(?) "Gray-blue marbling, glimmering,

On 1969 Jul 19 at UT 06:30 Whelan (Wellington, New Zealand) observed a
pulsating glow in Aristarchus crater, extending towards the north. The
Cameron 1978 catalog ID=1162 and weight=2. The ALPO/BAA weight=2.
On 1970 apr 11 atUT 05:29 Lucas (San Diego, CA, USA, 10" refelctor,
seeing=fair) and others (Oregon, USA) obtained a photometric record of
light level changes in Grimaldi crater. Visible reports by others
during the same time. The photometer paper chart pen moved off scale on
a 10mV scale adjusted to 1000mV. The peaks correlate with the visible
observers from California and Oregon. Bright flashes, 3-5 events
(confirmation during the Apollo 13 watch). The Cameron 1978 catalog ID=
1237 and weight=5. The ALPO/BAA weight=4.
On 1983 Sep 11 at UT 23:52 K.P. Marshall (Columbia, 12"
reflector, x268, seeing II), whilst sketching the crater
Janssen noticed a tenuous red patch on the southern junction
of the valley which joins Fabricius to A. Nothing resembling
this found on nearby areas. The ALPO/BAA weight=1.
On 2010Apr18 at UT 20:45-21:00 P. Grego (St Dennis, UK, 17"
reflector - first practice run) observed that Aristarchus in
Earthishine was the brightest that he had seen it before. The
effect had faded to normal in the next 15 minutes though. "The
bright spot was initially thought to be part of the wall of
Aristarchus, but on closer examination the spot was probably the
crater’s central peak. At around this time I estimated the
brightness of the peak to be around magnitude 8, but this is a
poor estimate as no suitable comparison stars in the immediate
vicinity of the field of view were to be seen. Aristarchus’
outline was visible, as was a clearly defined sweep of
brightness to its west (presumably the high albedo markings
southeast of Herodotus) and another illuminated area to the
north of Aristarchus (presumably the Vaisala area), and a small
illuminated patch on the eastern flanks of Aristarchus. No other
areas of the Moon in earthshine appeared to be as bright as
these markings, and there were certainly no other clearly-
defined spots as brilliant as the one that lay in Aristarchus. A
watch was kept until 22:00 UT, when the Moon went out of view
behind a tree. During this period it appeared that the spot was
becoming less bright and less clearly-defined, although the
other albedo markings in its vicinity remained visible; this may
have been a consequence of the Moon’s diminishing altitude.
ALPO/BAA weight=1.
In 1821 May 06 at UT 21:45 Ward (England? Large aperture
telescope, x80), Bailey (England?) and Olbers (Bremen, Germany,
refractor) observed in the Earthlit part of the Moon an apperent small
comet like feature extended from Aristarchus towards Grimaldi. The
light was similar to a glow worm. The observer had never seen anything
like it. The cameron 1978 catalog ID=89 and weight=5. The ALPO/BAA
weight=3.
Messier 1981 Sep 03 UT 19:15-19:55 Observed by Evans (England, 254mm
Newtonian, seeing II-III, transparency fair). "Messier was under going
obscuration" BAA Lunar Section Circular report. ALPO/BAA weight=1.

On 1969 Jul 20 at UT 0530-0540 Younger and Byl (Victoria, BC, Canada,
48" reflector) saw a fuzzy brightening near Aristarchus of less than
0.5 minute of arc diameter (Apollo 11 watch). The Cameron 1978 catalog
ID=1171 and weight=4. The ALPO/BAA weight=2.
On 1967 Jul 20 at UT 07:00 Whelan, (Wellington, New Zealnd) saw a
pulsating glow from Aristarchus crater, and this continued, although
less pronounced. This was during the apolo 11 watch. The Cameron 1978
catalog ID=1172 and the weight=2. The ALPO/BAA weight=2.
Proclus NW ray 2003 Sep 02 UTC 02:20-03:35 Observed by Haas (Las
Cruces, NM, USA) "Everyone knows the bright ray running northwest from
Proclus. In this view from 2:20 to 2:36, UT on September 2 I remarked a
thin, pink southwest border to the ray. One thinks of chromatic
aberration, and the position supports this interpretation; but other
bright lunar features showed no such effect. The pink border lay 1 to
2.5 diameters away from Proclus (S=2, T=3.5). At 2:55, UT (S=1-2, S=
3.5) the border was gone; neither its appearance nor disappearance was
observed. At 03:25 UT there is no sign of the pink border (S=2, T=3),
moreover the Moon was lower, so atmospheric dispersion must be greater
by now? 12.5" Newtonian x321 at 02:20-02:36, x202 at other times.?"
Note that experiments to simulate spurious colour using Adobe Photoshop
were able to recreate colour in the correct place on the NW ray -
however there should have been colour reported on the SW ray too and
there was no mention of this, therefore the observational report is
intriguing. The ALPO/BAA weight=2.
On 1974 Feb Weith-Knudson (Copenhagen, Denmark, 12" refrlector, x72)
observed a magnitude 7.7 flash (comparison between SAO093043=mag 7,8
and SAO093052 mag=7.5 that happened to lie in the field of view at the
time) in Earthshine. The observer speculates whether this was a lunar
meteorite impact or a reflection from an artificial satellite (or
indeed as Cameron suggests from an Earth meteor?). The cameron 1978
catalog ID=1388 and weight=0. The ALPO/BAA weight=1.
M. Price of Camberley, UK noticed that an area in relation
to the central area of the floor could not be resolved. Averted
vision was used, but this did not help to resolve detail. The crater
was close to the terminator and was in general sharply in focus
apart from the suspect area. No spurious colour seen. Sketch
supplied.P. Foley wonders if the effect was due to the resolution
limit of Price's scope? Cameron 2006 extension catalog ID=78
and weight=2. ALPO/BAA weight=2. 6" reflector x64 and x120.
Seeing=III-IV and Transparency=good.
On 1969 Jul 20 at UT 0845 McIntosh (Auckland, New Zealand, 14"
reflector) saw Aristarchus crater to be brighter in red light. This was
during the Apollo 11 watch. The Cameron 1978 catalog ID=1173 and
weight=3. The ALPO/BAA weight=3.
On 1975 Mar 18 at UT17:30 M.Kidger (Winterbourne Down, Bristol, UK,
60mm refractor, x36, very good conditions with a very sharp image and
the sky was almost perfectly clear apart from a very few small clouds).
In Mare Crisium it was observed that only a ray of Proclus could be
seen to cross the floor - normally there are at least four craters
visible inside mare Crisium on good nights and at least one being
visible under bad conditions. So despite it being very clear and the
image quality being good, the observer found it odd that no craters
were visible on the floor of mare Crisium. This is a BAA Lunar Section
report. The ALPO/BAA weight=2.
On 1993 Dec 19 at UT 16:00-17:00 S. Beaumont (Cambridge, UK, 12"
reflector, x230) observed in Theophilus that the "c.p. > reddish brown
tint to SW (on peak?)" but suspected that it was probably spurious
colour, however no colour was seen later. The ALPO/BAA catalog ID=469
and the weight=3. The ALPO/BAA weight=2.
Theophilus 1972 May 19 UT 23:48 Theophilus observed by Ruchatz (51N

30cm reflector, seeing IV, transparency moderate, very litle
spectral dispersion noticed - Wratter 25 and 44a filters used)
UT 21:16-21:19 Censorinus slightly brighter in red and more
detail seen. Observed other features before and after this.
Checked again UT21:31-21:40 - same appearance. Torricelli and
Torricelli B in comparison looked normal with other craters of
similar size. ALPO/BAA weight=1.
Proclus NW ray 2003 Sep 03 UTC 02:46-03:07 Observed by Haas (Las
Cruces, NM, USA) "The curious reddish edge to the conspicuous bright
ray running N2 from Proclus is seen again (x321, x366 (S=1-3, T=3.5-
2.5). It lies on the SW side of the ray, with no corresponding blue
border on its NE edge. The effect persists as the Moon drifts across
the whole eyepiece field. However at 03:46 (x202) the coloured edge is
not recognized now, but perhaps only because of worse conditions (S=3,
T=2) 12.5" Newtonian reflector used." The ALPO/BAA weight=3.
On 2010 Apr 20 some time between UT 22:00 and 23:00 I.

Zealand, 4" f/10 reflector) "observed two possible L.T.Ps. on the edge
of the terminator near the crater Archimedes. They appeared to be two
bright points of light about the size of Mount Piton. They seem to
form a triangle with Mount Piton. He observed them for two hours and
they were still visible when he ended his observing session. He was
observing with a 4" f10 reflector. Then Moon age was 7.9 days old and

On 1988 Jul 22 at UT 02:15-04:00 P.W. Foley (Kent, UK, 11"
reflector) made a sketch of a dark area of the (East) floor of
Proclus that revealed a large anomalous dark region - there
should be no shade here when the sun is at an altitude of above
50 deg!. BAA lunar section archives reveal similar dark shadings
- however on this night it was a different shaped dark area. The
appearance was confirmed by several observers. Foley reported
that the region affected stretched from Proclus to Theophilus.
The TLP was seen in the USA too by D, Darling as early as
01:31UT and by others on his TLP network - brightness
measurements of the "c.p." were 3.5 and the remainder of the
floor was 5.5. However the observers did not all agree on the
same position for this dark area. The Cameron 2006 catalog ID=
331 and the weight=2. The ALPO/BAA weight=2.
Flash seen in Ptolemaeus (A?) - possibly a meteor. Cameron 1978

2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw
Mons Pico to be incredibly bright. Adee reported naked eye visibility,
though this does not show up in later CCD images. Jarwaski saw another
nearby Mt very bright as well. This has been assigned an ALPO/BAA
weight of 1, though I suspect it is just normal for Pico to get quite
bright at sunrise.
Patches of brightness seen in the area between craters Aratus and Joy.
Seemed to the observer to be perhaps slightly brighter than one would
expect - the observer thought that their observation only barely
constitured a TLP but decided to send the report in anyway. This
has been assigned an ALPO/BAA weight of 1.
Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson,
Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw
something in Proclus, alerted Jamieson who saw nothing unusual
at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw
Proc. fluctuate. Red & blue filters showed some reduction in

On 1983 Sep 15 at UT 05:20-05:24 Louderback (South Bend, WA, USA,
8" reflector and 3" refractor, seeing poor) found that the west wall of
Eimmart was unusually bright (8.3) and apparently it was almost as
bright as the "WEBS(of Aris?) at its brightest". The crater was
apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID=

On 1989 Jun 12 at UT 21:18-22:25 G. North (Herstmonceaux, UK,
Coude, seeing=V) noted at 21:18UT that Torricelli B was
"barely visible"- possibly this was seeing related. M. Cook
(Frimley, UK, 8" reflector, seeing=IV) found Toricelli B to be
ëxtremely dull - impossible to judge shadows on floor in
contrast to Cens." Holmes (Rockdale, England, UK, 8"
reflector, seeing=II-III) at UT21:30 also found Toricelli B
difficult to find at magnifications less than 200x. Cameron
comments that "Dulling is common on it at high Sun but
illumination doesn't seem to be the cause or related". The
Cameron 2006 catalog ID=365 and weight=5.

On 1988 Jul 23 at UT03:07 D. Darling (Sun Praire, WI, USA, 12"
reflector, x150, seeing = 6/10) discovered that the dark area on the
floor of Proclus, seen earlier by UK observers was still present, but
less so (?) and the shape changed. When viewed through a green filter
it was less distinct. "Change with two other filters. Polarizer gave a

Aristarchus 1976 Jan 14 UT 20:00-23:00 Observed by P.W. Foley
(Wilmington, Kent, UK) - Deep Violet/Blue spot interior N/WW
corner. No colour seen elsewhere. It was only a blue spot on the
Jan 13. ALPO/BAA weight=1.
Aristarchus, Herodotus - 1967 Sep 16 UTC 23:50-23:55 observed by
Seeliger (Dresden, Germany, 30" reflector, 90, 140x) "Dark streaks on
E.(ast. ?) outside walls of both craters. No shadow from Herod. wall.
Drawings (wall < 18 deg slope if no shadow normally)." NASA catalog
weight=3 (average). NASA catalog ID=#1044.
Plato 1976 Jan 14 UT 20:50 Observed by J.H-Robinson (Teignmouth,
UK, 26cm Newtonian, Wratten 25 and 44a filters, x200, seeing
fair to poor). The Plato floor patches were clearer in red than
in blue light. ALPO/BAA weight=1.
Schickard 1944 Aug 31 UTC 21:00? Observed by Wilkins (Kent, England)
described in the NASA catalog as: "Saw a mist in it which was gone next
nite. interor was dotted with white spots, contrasting sharply with
dark areas. All very clear on Aug 15 at sunset". 8.5" reflector. NASA
catalog weight=4 {high). NASA catalog TLP ID No. #492. ALPO/BAA
weight=3.
On 2010 Apr 27 at UT 00:10-00:30 and 01:45-02:00 P. Grego (St
Dennis, UK, 20 and 30cm reflectors) noticed a craterlet just
to the east of Briggs and an E-W trending lineament or wrinkle
ridge that did not show on NASA LAC charts. Further checks did
not reveal it on Lunar Orbiter mosaics, but the craterlets
(and not the E-W trending ridge) were visible in LROC
topography data. The ridge is possibly a very low relief
feature that shows only under very shallow illumination
conditions. The ALPO/BAA weight=1 until we get confirmation at
repeat illumination.
Aristarchus 1967 Sep 17 UTC 02:05-02:21 Observers: Delano (Fall River,
MA, USA) and Corralitos Observatory (Organ Pass, NM, USA). The former
used a 12.5" reflector at 400x and the latter a 24" reflector. The NASA
catalog states the following: "A rimtop cratelet on SW rim appeared
almost as bright as c.p. thru a Wratten 25 filter (red) but no brighter
than a lower central wall & rim thru a Wratten 48 (blue) filter. Inner
W. slope of craterlet displayed a bright red color which became less &
less noticeable until 0212h It was no longer brighter than other parts.
At 0217 it flared again brighter red for 1m. (indep. confirm. of
Seeliger for activity in Aris. ?) Corralitos MB did not confirm. NASA
catalog weight=4. NASA catalog TLP ID No. #1045.
ALPO/BAA weight=2.
On 1975 Mar 25 at UT18:50-20:50 P.W. Foley (Kent, UK) observed
blue/grey in Aristarchus. The ALPO/BAA weight=1.
On 1983 Sep 20 at UT 05:08-06:13 Louderback (South Bend, WA, USA,
3" refractor, x150, seeing poor and chromatic aberation on the limb)
detected "purple"in the vicinity of Aristarchus crater and this was
stongest on the north and north west external rims, however there was
no "violet glare"from inside the crater. However the region of the
central peak was very bright - though he could not detect the central
peak. The brightness of the TLP was 4.5 and it should normally be 3
(nimbus area). Near the "big plain"it was 7. The chromatic aberation
seen on the crater. There was also violet on the northen wall of
Herodotus crater and the Cobra Head. Ït appeared dark blue in the blue
filter", the surrounds remained gray". Apparently on the 26th the"ring
was still dark with faint violet - nearly normal". Cameron comments
that the TLP was due to spurious colour. The Cameron 2006 catalog ID=
229 and the weight=3. The ALPO/BAA weight=2.
On 1975 Mar 25 at UT19:59-20:02 P.W. Foley (Wilmington, Dartford, Kent,
UK, 30cm Newtownian) observed blueness along the inner southern wall of
Plato. This is a BAA report. The ALPO/BAA weight=1.
On 1985 Jul 01 at 02:00-03:00 UT K. Marshall (Medellin, Columbia)
observed thatTorricelli B was very bright - verified using a C.E.D. No
colour was seen though. the Cameron 2006 catalog ID=279 and the weight=
4. The ALPO/BAA weight=3.
On 1980 Jan 01 at UT 00:10-00:21 A.C.Cook (Frimley, UK, 12" reflector,
Wratten 29 and 44A filters, Seeing II-III and transparency poor-
moderate) suspected that the floor was slightly brighter in blue light
than in red. No such effect was seen earlier at 23:54-23:57. Cameron
2006 catalog ID=81 and weight=3. ALPO/BAA weight=1.
Grimaldi 1839 Jun 24 UT 22:00? Observed by Gruithuisen (Munich,
Germany) "Smokey, grey mist". NASA catalog weight=4 (high). NASA
catalog ID #117. ALPO/BAA weight=2.
In 1959 Nov (Day unknown) at UT 21:15-22:15 Bradford (South Shields,
UK, 15" reflector, x480) observed in Littrow: "Cocealed by a dusky cloud.
Appeared to be stream or smoke. No change in 1h. Following week no
trace. (SR Nov 5, SS Nov 18. Says he obs. at time of unmanned landing,
but there were none in Nov.) Similar to #722". The Cameron 1978 catalog
ID=726 and weight=2. The ALPOS/BAA weight=2.
On 1983 Oct 19 at UT 21:09-23:40 G. North (Bexhill on Sea, UK, seeing
III) found Aristarchus crater to be slightly blue in colour, and very
bright, despite the fact that no colour was seen elsewhere on the Moon.
At 22:08UT Foley (Kent, UK, 12"reflector, seeing II) obtained an
extremely high CED brightness measurement and also picked up a "blue-
violet" cast, especially inside the west rim, furthermore he saw noe
detail in it. The Cameron 2006 catalog ID=230 and the weight=5. The
ALPO/BAA weight=3.
On 1989 Jun 17 at UT 06:33-07:16 R. Manske (Sun Prairie, WI, USA, 1"
refractor) sketched a nebulous spot near to Herodotus crater that at
06:49 (when he tried some filters out) was visile through red, blue and
yellow filters, though it was slightly fainter through the red filter.
The Cameron 2006 catalog ID=366 and the weight=3. The ALPO/BAA weight=2.
Aristarchus 1963 Oct 30 UTC 22:00? Scarfe (Cambridge, UK)
observed a 30% enhancement at 540nm in the spectra of
Aristarchus. The Cameron 1978 catalog ID No. is 778 and weight
is 5. The ALPO/BAA weight=1 because Oct 30 is not mentioned in
Cameron's refernce.
In 1963 Oct 30 UT 22:00? Scarfe (Cambridge, UK) observed a
30% enhancement at 540nm in the spectra of Copernicus. The
Cameron 1978 catalog ID No. is 778 and weight is 5. The
ALPO/BAA weight=1 because Oct 30 is not mentioned in the ref
that Cameron give's to Scarfe's paper.
Plato 1938 Feb 14 UT 00:25 Observed by Fox (Newark, England,
6.5" reflector, x240) "Prominent gold-brown spot on E. wall
with yellow glow without definite boundary, spreading over
floor." NASA catalog weight=3. NASA catalog ID #431. ALPO/BAA
weight=3.
Aristarchus 1976 Jan 15 UT 19:30-20:50 Observed by P.W. Foley
(Kent, UK, 12" reflector) - Aristarchus was abnormally bright
(Cameron suspects that this is a confirmation an explosion
effect seen earlier by Greenland: "On 1976 Jan 15 at 19:45Ut
Greenland (Crawley, UK, 7x50 binooculars) thought that they
saw an "explosion" on the Moon (in the general region of
Aristarchus) for a fraction of a second, followed by a bright
spot in the same position (not an astronomer). After
discussions with others, decided it was a moment of transition
to greater intensity (better seeing?). Moore thinks it was
atmospheric but says it should be on record. Cmeron's 1978
catalog ID=1425 and weight=5". For the Foley report: Cameron
1978 catalog TLP ID=1427 and weight=5. ALPO/BAA weight=1.
