On 1979 Sep 14 at 13:30-14:42 D. Louderback (South Bend, WA, USA, 8"
reflector, x146) found that half of the northern rim was "extinguished)
in the violet filter (made the crater look U-shaped), but appeared
normal in red and other filters. Cameron 2006 ID=67 and weight=4.

On 1991 Jan 29 at UT17:34-17:52 A.C. Cook (Frimley, UK, 20cm reflector
+ image intensified CCD camera, transparency moderate to very poor)
observed that Aristarchus was fainter than a nearby magnitude 7.3 star
(SAO 146315) and may have varied in brightness and size. However the
image intensifier output was quite grainy. No obvious signs of impact
flashes or cosmic rays seen during a visual inspection of the video
tape recorded. Foley commented that from UT 18:53-19:10 the Earthshine
was strong with the naked eye and Aristarchus was bright as expected.

On 2012 May 26 UT21:21 J. Moeller (Syracuse, NY, USA, using a
Konica Minolta DIMAGE Z5 digital camera, f/7.1, 1/250 sec
exposure, ISO-50, 69mm focal length, digital zoom x3) captured
a hand held image of the Moon in daylight. On the SW limb of
the dark side of the Moon a bright spot can be seen. This has
a brightness comparable to that of Mare Serenitatis. There is
also a fainter dark blurred marking further inside the dark side.
ALPO/BAA weight=1.
On 1994 Apr 17 at UT02:00 R. Zit (Madison, WI, USA) whilst observing a
grazing lunar occultation, found that Aristarchus (and the surrounding

On 1982 Jul 28 at UT20:38-20:48UT A.C. Cook (Frimley, Surrey, UK, 12"
reflector, seeing IV-V, some spurious colour prsent) observed that the
central peak of Alphonsus was brighter in red light than in blue, so
much so that at the start of the session the peak could hardly be seen
in blue light. The central peak varied in brightness in red light but
not in white light. The central peak of arzachel was brighter than that
of Alphonsus in white light but had no colour - Arzachel's central peak
did however appear to fade in brightness over time (or was it Alphonsus
getting brighter?). Cameron 2006 catalog ID=177 and weight=3. The

On 1975 May 18 at UT2115-2145 C. Lord (St Annes-on-sea,
Lancashire, UK, 76mm f/16 refractor, x170, Wratten 25, and 44a
Moon blink filters used, Transparency 4.5/5, no wind, S=F). The
west flank of Maginus, and the interior, appeared to be partly
obscured. No other features in a similar position along the
terminator were obscured. No colour blink was detected with the
filters, though a pronounced red/white light blink was noted; the
device employed a N.D. x4 filter. By 21:45UT the floor was no
longer obscured and only Magninus G was masked in a white haze;
however immediately adjacent to the terminator was an ill defined
misty patch lying where the outer flank of maginus would have
been visible. The rest of the terminator was sharp. The
obscuration was only seen to advantage in blue and int. light,
and the blue/int blink was only very slight. Findlay and
McDonnell observed 21:30-23:00 using a 25cm refractor (Seeing II-
III) but failed to see anything unsual. NASA catalog weight=3.

Vallis Alpes 1983 Jun 18 UT 22:01-22:23 P.Madej (Huddersfield, UK,
77mm refractor, x83,x250, seeing II-III, transparency fair).
After studying the whole length of this valley, the observer saw
a change in "albedo" and a small change in colour of the valley
floor near to the Plato end. This colour was not seen in a
yellow Wratten 15 filter but was noted in a purple Wratten 35
filter, and was strong in a red filter. Also the crater
Trouvelot was not seen at x250 with a x2 Barlow.Wratten 25.

Daniell 1983 Jun 18 UT 22:06-22:25) P.Madej (Huddersfield, UK,
77mm refractor, x83,x166, seeing II-III, transparency fair).
Noted on the inside W eall a faint red rose like glow (with a
diameter? about it). The red glow varied in brightness with a
period of about 2 minutes. It looked somewhat brighter at x166.
The glow was still visible when the observation ended at 22:15

On 1979 Sep 29 at UT10:00-12:00 S. Turner (Maryborough, Australia)
observed a strong beacon like flash in white light that moved back and
forth in the east wall of Plato (very bright) and Mons Pico. tried
changing eyepiece and the field of view, but this wasn't the cause of
the effect. A check at 11:07UT did not show the effect, but it was back
again by 11:18UT being more pronounced at Mons Pico than the east wall
of Plato. SSW of Mons Pico was also blinking slightly. At 11:32 the
blinking effect was irregular 5-10 sec and this continued until
12:00UT. Cameron 2006 catalog ID=71 and weight=0 but she suggests
atmospheric scintillation as a cause. ALPO/BAA weight=1.

On 1969 Mar 27 at UT 18:42-18:47 Ringsdore (England, 15"
reflector, x350), Moseley (Armagh, Northern Ireland) and P.
Moore (Selsey, UK) observed nothing unusual in Alphonsus at
18:40UT, but at 18:45UT Ringsdore saw a blurring. At 18:43UT
Mosely saw a reddush-orange patch and this was confirmed by
Moore. NNW of the central peak, Mosely got a blink, but Moore
did not because of too much stray light. The colour was like
Jupiter's red spot, but less pronounced. The Cameron 1978
catalog ID=1118 and weight=5. The ALPO/BAA weight=4.
Plato 1932 Apr 15 UT 06:57 Observed by A.V. Goddard & friend

On 1974 Jan 03 at UT 18:30 a Norwegian amateur astronomer,
Hoydalsvik (Hakonsgate, in West Norway, 60mm refractor)
photographed the Moon using High Speed Ektacrome (400ASA) film
with good focus. The TLP was located on the southern slope of
Sasserides H and was pink in colour with some bluish in it.
The coloured area was circular with a diameter of 0.5 minutes
of arc. Only one exposure was taken. The photograph was
checked by the Institute of Theoretical Astrophysics,
University of Oslo. Although they thought it was probably
genuine (could have been an impact flash?) suggestions by the
BAA lunar section favoured static electrical discharge on the
film. It is uncertain whether the film was ever examined by a
Photographic developing lab such as Kodak, who would be able
to tell if it was real or an artefact. ALPO/BAA weight=1.
On 1984 Jun 09 at UT 04:55-05:14 P. Jean (Outremont, Canada) detected
in the dark side of the Moon, a few km east of Kies crater, a bright

Archimedes 1971 Aug 01 UT 22:00(?) (19:00 originally given
probably local time) Miranda (Plaui, Brazil, 4" refractor,
x80) observed two grooves going from east to west, broadening
towards the west, across Archimedes. A drawing was supplied.
Apparently this was the first time that this was ever seen.
Cameron suggests rays? and also says that in fact a similar
phenomenon reported before in neasrly the same position
(Apollo 15 watch?). The Cameron 1978 catalog ID=1303 and

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 west (IAU?) 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 1964 Jun 21 at UT 03:43-05:44 Harris, Cross and Helland (Whittier,

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

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 see 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
weight=1.
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 north-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.
On 1985 May 30 P.Madej (Huddersfield, UK, 77mm refractor, x111

USA, 12.5" reflector, x159 and 3" refractor x90, seeing 5/10,
transparency 3/6) found that Aristarchus was brighter through
a red filter than through a blue filter on its western wall.
He checked Aristarchus in two telecopes and obtained the same
result. The Cameron 2006 catalog ID=419 and the weight=4. The
ALPO/BAA weight=3.

(Dartford, England, 12" reflector, S=II) and Moore (Sussex,
UK, 15" reflector x250 S=IV) and Argent and Brumder (Sussex,
UK). In early sunrise conditions, W. wall was less brilliant
than usual -- matched only by Sharp, Bianchini, & Marian.
Extraordinary detail could be seen on this wall. Also noted
intense & distinctly blue color entire length of W. wall. 3
others corroborated detail, but not color. Moore found things
normal & saw Aris. brightest at 2030-2125h tho Argent &

On 2013 Apr 22 UT 01:39-02:37 P. Zeller (Indianapollis, USA,
10" f/4 reflector, x200, seeing 6, Transparency 3 - scattered
cirrus) observed visually (depicted in sketch) the two closely
spaced NW wall dark bands) to have a rusty-red hue. The colour
of these bands did not change over the period of the observing
session. Images were taken, but resolution and image S/N is
not sufficient to resolve separate bands here, or to detect
colour. The ALPO/BAA weight=1.
On 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector,

Proclus 1990 Mar 09 UT 00:12-00:13 Observed by Marie Cook (Frimley, UK,
3.5" Questar telescope) observed a "long plume of light" the brightness
was the same as the wall region. It went from the southern rim about
half of the way across to the centre in the "northerly". The plume
feature was not seen at higher magnifications. Change in brightness
also noted. The Cameron 2006 catalog ID=394 and the weight=1. The
ALPO/BAA weight=1.
On 1993 Jun 02 at Ut 04:30-05:45 S. Beaumont (Cambridge, UK) saw that
the shadow of the Cobra's Head in Schroter's Valley was lighter and
more diffuse seen at user defined locations of C or B rim (these were
black versus medium gray for Cobra's Head). The TLP had vanished by
05:45UT. The Cameron 2006 catalog ID=462 and weight=3. The ALPO/BAA

around the Moon, obtained images of the Cobra Head region of
Aristarchus crater that suggested a ~15x colour ratio 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
weight=1.

2s then image blurred at 5-10s (atm) at 2034 became pink). At 21:35UT
M. Mobberley (Suffolk, UK) found a white patch in the crater centre and
a mag 8 flash was seen (confirmed independently by a 2nd observer ~
113km away)- there was no shadow. At UT 20:30 P.W. Foley (Kent, UK,
12"reflector, seeing excellent) found no colour, but the brightness was
changiong and he confirmed the bright patch on the crater's floor,
variable 22:15-22:25UT, "then expanded over rim". The Cameron 2006
catalog ID=277 and weight=5. the ALPO/BAA weight=4.

On 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st
7:24PM PST) saw a naked eye flash on the Moon. The observers were
glancing up at the Moon in daylight when they saw a bright white flash
(observer and his wife together) in the upper/mid Mare Serenitatis
region, west of the crater Posidonius. "Larger than how Venus appears".
"It was a quick flash like white, intense lightning. I'm not sure how
to report degrees of arc but if the face we see is 900, and we start
from the east then the flash occurred about 225 arc seconds to the
west. This was observed by the naked eye, with clear skies between us
and the moon." The observers checked for signs of aircraft vapour
trails but could not see any. There is a possibility that it could have
been sun glint from an Iridium satellite, but this needs to be checked
out and usually these last longer than the observed effect. It would be
useful to obtain whole Moon images under the same illunination and
libration so that we can judge this observation properly. 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
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

and Kepler were of the same brightness. The ALPO/BAA weight=1.
Plato 1869 Aug 23/24? UTC 23:00-01:00? Observed by Gledhill? (Halifax,
England, 9" refractor) Group I of craterlets (as designated by several
famous obs. before) exhibited notable illumination, accompanied by a
single light on a distinct spot. (if obs. similar to Ap 1870 obs. then
date =Au 23-24). NASA catalog weight=2 (low). NASA catalog ID #162.
On 1975 Dec ?? at 19:00UT P.W.Foley (Kent, UK), and possibly P. Moore?
(Selsey, UK) - unusual events were reported which might have been due
to minor structral changes. Albedo=76% (=7.6?). Cameron 1978 catalog
ID=1425 and weight=3. ALPO/BAA weight=1.
Aristarchus 1975 Dec 19 UT 22:45 Observed by Foley (Kent, England)
"Suspected anomaly in it", NASA catalog weight=1 (very low). NASA
catalog ID #1424.
In 1942 Feb 02 at UT 18:20-19:15 Y.W.I. Fisher (Brussels,
Belgium) a whitish glow near the Earthlit limb, near to
Kepler (37W, 7N). The duration of the event was 55 min.
The Cameron 1978 catalog ID=488 and weight=2. The
ALPO/BAA weight=1. Ref. p220-221 IAU Symposium
No. 14 - The Moon.
On 1975 Dec 19 at UT22:45 P.W. Foley (Kent, UK) suspected an anomaly in
Aristarchus. Cameron 1978 catalog weight=1424 and weight=1. ALPO/BAA
weight=1.
Aristarchus 1983 Oct 23 UT 19:00-01:30 Observer: Foley (Kent, UK,
12" reflector, seeing=II) noiced at 19:00UT an extended bright
spot on E wall and extending beyond. This was brighter than other
areas of the crater. There was also occasional star-like
glistening. Foley comments that the inside of Aristarchus was
slightly obscured. The TLP started fading from UT20:30 and
finished by 01:30UT. six out of nine independent observers
confirmed the effects seen. In total 14 observers observed, 9
reported back and 6 found abnormalities in Aristarcus though all
encountered variable seeing conditions - some had spurious
colour. Cameron comments that this was one of the best
recorded/confirmed TLP events. All CED brightness measurements
obtained were very high. Moore, Nicolson and Clarke (5" refractor
and 15" reflector, 230-350xseeing III) found the crater to be
very bright at 19:11UT through a 5" refractor and there was a
blob on the east rim (Bartlet's EWBS?) at 19:14UT. Nicolson also
saw a very bright star-like area on the eastern wall but this was
not defined as it usually is. The crater was also very bright at
22:43UT using the 15" reflector available to these observers. At
01:07UT they used a Moon blink and discovered that the bright
region was bright in blue light and less bright in red - although
this was not a detactable blink when switching rapidly between
filters. They found that the crater had returned to normal by
01:15UT. M.C. Cook (Frimley, UK, seeing III-IV) observed a large
diffuse spot on the east of the crater that was brighter in blue
than in red light and the CED device gave a high reading. J.D.
Cook (Frimley, UK, seeing III-IV) made a skecth that showed the
bright spot extended on the east wall - again the CED reading was
high and a lot of detail was visible on the floor. A.C. Cook
(Frimley, UK, seeing III-IV) also noted remarkable detail and the
bright (as confirmed by CED) blob on the eastern rim. G. North
(Sussex, UK, seeing III-II) also confirmed the bright blob on the
eastern wall. Wooller found the north west wall was a dirty
yellow colour - though no colour was seen elsewhere in or outside
the crater. Mosely found the crater to be bright and his sketch
revealed the extension of the bright blob on the eastern rim and
again a great deal of interior detail. Amery (Reading, UK, seeing
III) found Aristarchus to be "a brilliant splash against dulled
background in violet filter, especially polarizing filter. CED +
polarizer readings high, but not as high as previous night".
Mobberley (Suffolk, UK, seeing III-IV) remarked that "spurious
colour a total mess around Aristarchus & nothing abnormal seen".
A photograph was taken at 20:50UT reveals the bright blob and
entire detail. Peters (Kent, UK, seeingIII-II) observed
Aristarchus with a UV screen from 20:15-21:23UT and comented that
althogh being very bright, there was no variation between white
and UV. It was checked with a Moon Blink device and the radial
bands were clearly seen in white light, < in blue. The Cameron
2008 catalog ID=233 and the weight=5. The ALPO/BAA weight=4.
On 1984 Nov 10 at UT19:15-19:50 R. Moseley (Coventry, UK, the Moon's
altitude was low) noticed that the region from the central peak and
over and onto the east wall looked unusual. 8 bands were visible, "two
on E. wall of c.p. strongest, surrounding collar grey increasing
intensely outward. Band at 2 o'clock position was very dark. Bright
spot on W. wall at 4 o'clock position." A sketch was made that
illustrates bands on either side with bright patch. The Cameron 2006
catalog ID=252 and the weight=2. The ALPO/BAA weight=2.
On 1988 Jul 31 at UT 07:09-08:10 D. Darling (Sun Prairie, WI, USA,
12.5"reflector, seeing=7/10 and T=3) did not detect the dark region on
the south east floor of Proclus (the TLP from a few days earlier), but
did see 2 "linear mounds". The Cameron 2006 catalog ID=335 and the
weight=0. The ALPO/BAA weight=1.
On 2011 Jan 21 at 22:30UT N.Longshaw (UK, 4" Achromatic
refractor, x128 & x160, Seeing III, transparancy average)
suspected on the eastern edge of Geminus, on the border of the
crater filled shadow and the eastern illuminated rim, a
brownish, almost speia hue. This extended for a short distance
from the floor shadow into the illuminated rim width and spanned
from the north to the south of the crater. For a comparison,
Cleomedes was checked but nothing unusual was noticed in its
shadow. The observer notes that Elger also saw a warm brown or
sepia tone. ALPO/BAA weight=1.
On 1989 Jun 21 at UT07:03-07:27, R. Manske (Sun Praire, WI, USA, 1
"refractor) found the colours pink and blue on Aristarchus, like the
previous day, however this time there was also an orange tinge on the
"back"" (North?) rim of Sinus Iridum and the same too on mare Crisium,
all the way past Plato, in the direction of Cassini. This colour was
not seen at higher magnifications. The Cameron 2006 catalog ID=368 and
the weight=0. The ALPO/BAA weight=1.
On 1989 Jun 21 at UT 07:03-07:27 R. Manske (Sun Praire, WI, USA, 1"

On 1966 Nov 11 at UT05:55-1000 Hall and Johnson (Port Tabacoo, MD, 16"
x400, S=VG), Nordling (MD, USA), Genatt (Greenbelt, MD, USA, 6"
refractor, x50, 20" reflector x400) and Wagman (Pittsburgh, PA, 30"
refractor) observed the folloowing on Aristarchus: "Color ob c.p.
detected with Trident MB, not seen vis. at Port Tobacoo. Network
alerted & 6 responded. 4 did not see anything unusual; 2 others did &
saw red on c.p. in 6-in refr., but not in 20-in refl. at 400x; other
saw indistinctness. Port Taboacoo obs. took 5 rolls of film in blue &
red & neutral. Phenom. not detectable on them, but focus poor. Blue
images had most detail, whereas would expect red or neutral to. Phenom.
still present at dawn in Moon Blink device". The Cameron 1978 catalog
ID=914 and weight=5. The ALPO/BAA weight=5.
On 1986 Apr 26 at UT 21:00 etimated) H. Miles (Cornwall?, UK)
found that Aristarchus was "still brighter in moments of
better seeing". The rim could be seen as a complete circle.
The Cameron catalog ID=283 and the weight=3. The ALPO/BAA
weight=1.
Messier A 1951 Aug 20 UT 01:48-03:00 Observed by P.Moore
(England, 8.5" reflector, x350). Bright cloud like circular
patch seen on S wall of Messier A. It was the brightest object
in the vicinity. Observations ceased due to the Moon setting
behind a tree. W.Haas thinks that this effect is not unusual at
similar colongitudes. Moore checked again under similar
illumination and still considers the Aug 20 appearance abnormal.
NASA weight=4. NASA catalog ID #545. ALPO/BAA weight=2.
On 1993 Dec 31 at UT 05:00-07:40 S. Beaumont (Cambridge, UK, 12"
reflector) "saw a patch of hazy light to NW (from c.p. alpha) at 0550
craters B & J shadow of alpha had not reached E wall yet, but at 0536
it did. Alpha > at 0550. Craters B & J to SE had faded, vanished at
0630. Hazy patch remained around peak, alpha low mainly to NE like a
comet's tail. Slightly reddish fringe to E wall. (shown in sketch)".
The above has been quoted in full from the Cmeron catalog because the
catalog desription is slightly ambiguous and any attempted summary
might make the description more unreliable. The cameron 2006 catalog
ID=470 and the weight=3. The ALPO/BAA weight=2.
Aristarchus 1975 Nov 18-19 UT 23:30-00:30? Observed by Foley (Kent,
England, 12" reflector) "Deep blue-viol. spot in NW (IAU ?) interior
corner. (seen occasionally with obscur. but dates not given)." NASA
catalog weight=3 (average). NASA catalog ID #1421."
On 1984 Nov 11 at UT21:00? Marshall (England) noted that there was no
normal brightness on the floor to most southernmost craterlet. The
Cameron 2006 catalog ID=253 and the weight=2. The ALPO/BAA weight=1.
On 1992 May 20 at UT 11:15 D. Weier (Sun Prairie, WI, USA,
naked eye and 7x50 binouculars, sky conditions excellent)
noted that Aristarchus and, an area, were very bright to the
eye. In binoculars the feature was quite sharp and distinct,
"> anything else on the Moon". When observing please try using
your eyes alone and then a small aperture and low
magnification. The Cameron 2006 catalog ID=447

On 1980 Aug 29 at UT07:32 D. Loudernack (South Bend, WA, USA, 8"
reflector, x140) found the south wall to have a broad dark band (only
visible in red light) at its base that covered nearly all of the
southern half of the crater. The brightness reading was 8.4 (in blue
light) and 4 (in red light). Cameron 2006 catalog ID=107 and weight=3.
ALPO/BAA weight=3.

(average). NASA catalog ID #196.
In 1937 Apr 29 at UT 09:30 Firsoff (Glastonbury, UK, 6" reflector and
filters) observed a slight greenish colour (Cameron says colour of
ground? no TLP?). The Cameron 1978 catalog ID=420 and Weight=4. The

On 1964 Jun 29 at UT 07:05-07:33 Bartlett (Baltimore, MD, USA,
4" reflector x240, S=5, T=4) suspected a violet glare? on the
EWBS of Aristarchus, but was too faint to be certain. The bright
art of the floor was granulated and had a ceppery tint. The
Cameron 1978 catalog ID=827 and weight=4. The ALPO/BAA weight=2.
1999 Jan 07 UT 01:57 C. Brook (Plymouth UK, 65mm refractor,

On 1980 Aug 31 at UT 08:00? D. Louderback (South bend, WA,
USA, 8" refletor x140) found the north wall to be very bright
in red light (this is not normal as it is usually bright in
blue - according to Cameron). The brightness was 9.7 (red) and
9 (blue no filter)compared to Eimmart's 8.7. Louderback
thought that they observed an orange-yellow tinge. Cameron
2006 catalog ID=108 and weight=3. ALPO/BAA weoght=2.
Triensecker Rille 1915 Jul 03 UTC 00:00? Observed by Markov (Russia)
"Several spots changed their shapes compared with Gordeenko's depiction

On 1982 Aug 11 at UT03:30-04:15 Mobberley (Suffolk, UK) obtained a
photograph and made a sketch that revealed a needle-like shadow from
the west wall to near by the central craterlet - the latter was quite
clearly visible. What were not visible were the other four craterlets.
The Cameron 2006 catalog ID=183 and weight=4. The ALPO/BAA weight=2.
Ptolemaeus 1825 UT 23:45 Observed by Schwabe (Germany?) "Bright spot"
NASA catalog weight=4 (high). NASA catalog ID #108. ALPO/BAA weight=3.
Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK,
10.25" reflector, x250, Wratten 44a and 25, seeing II) noted
that Aristarchus was surrounded by a dark area in the blue
filter. They did not regard this as a TLP at the time. However
because Aristarchus is surrounded by blue material in real life,
this should have been brighter? For this reason, despite the
observer regarding this as a negative TLP, an ALPO/BAA weight=1
has been applied.
