On 1988 Apr 20 at UT02:06-03:00 D. Fryback (Madison, WI, USA, 8"
reflector, S=3-4) commented that Aristarchus crater looked like a "city
from high above "glowing under a cloud". Spain (Fairfield, KY, USA, 8"
reflector, S=VG) detected a streak and flashes but reports that the
crater was not "glowing", though it was the brightest feature in the
Earthshine, but Kepler and Copernicus were bright too. Aristarchus was
brighter in shorter exposures than in longer exposures. The Cameron
2006 catalog ID=326 and weight="confirmed". The ALPO/BAA weight=2.
On 1992 Jun 04 at 01:28UT whilst driving home K.Jenks (NASA JSC)
observed with the naked eye a bright flash near to and slighly
south east of the middle of the Moon. ALPO/BAA weight=1.
Bright point on dark part. Cameron 1978
catalog ID=38 and weight=5. ALPO/BAA catalog

In 1832 Dec 25 at 18:00UT Piazzi-Smyth (Edinburgh, Scotland) observed a
bright spot near Aristarcus. The Cameron 1978 catalog weight=4 and the
ID=112. The ALPO/BAA weight=3.
On 1978 Mar 13 at 17:25UT V.M. Chernov (Soviet Union) observed that the
northern cusp was elongated into Earthshine, 4.6 days after New Moon.
One day before this the cusps appeared nromal to him. The ALPO/BAA
weight=1.
On 1968 May 02 at UT 01:20-02:14 Doughty (Red Bank, New Jersey, USA,
8" reflector, x120) observed a bright area in Aristarchus, surrounded
by a faint glow. May have been atmospheric dispersion. Glow fainter at
01:56UT and imperceptible at 02:14UT. Kelsey and Ricker consider the
observation abnormal. The Cameron 1978 catalog ID=1070 and weight=3.
The ALPO/BAA weight=2.
On 2012 May 25 UT 05:35 Brenner F crater was recorded in a larger
area image by M. Collins (Palmerstone North, New Zealand, ETX-90
with LPI imager (monochrome mode) - seeing not good). He took a
sequence of 108 images from 05:35-05:40UT, and in the 65th frame,
a light spot, approximately 4 pixels wide can be seen just
outside the western illuminated rim of Brenner F. It is not
visible in any other frames. The exposure time was 0.125 Sec.
Because the western edge of the spot is very sharp, and the rest
of the Moon is slightly blurred due to seeing, it is thought that
this was most likely a cosmic ray event in the CCD camera - the 4
pixel width was perhaps contributed to by the image compression.
It could also be some bright surface spot that was made invisible
most of the time by poor seeing, and then during a brief period
the atmosphere is sharp enough at that locality to make it
visible. ALPO/BAA weight=1.
On 2009 Jan 30 ay 22:35:20UT +/-2 min R. Masini (Perth, Australia) saw
a bright clound just west the south pole and along of the southern
limb. The effect lasted a few seconds and faded. It was seen with the
naked eye. There was a grazing occultation of a 6th magnitude star from
this site, however the star would have been in the wrong place at the
time of the TLP. The ALPO/BAA weight=2.
On 1992 Dec 29 at UT 17:42-17:54 A. Dollfus (Meudon, France, 1m
aperture telescope used) detected evidence for a dust cloud using CCD
polarimetry. The ALPO/BAA weight=5.
On 1975 Dec 08 at UT18:00-20:40 P.W. Foley (Wilmington, Kent,
UK, 12" reflector, x60-x624, seeing II, slight mist) found
Aristarchus to be less well visible than features such as:
Grimaldi, Reiner, Darwin/Byrgius, Kepler, Plato and Sinus
Iridum. Earthshine was exceptionally good tonight and was
orange/red in colour. Photographs were taken and these confirmed
the apparent dullness of Aristarchus. ALPO/BAA weight=2.
On 1991 Jun 17 at UT 20:30 T. Castro (Sao Paulo, Brazil, 24"
reflector, x500) observed "Large white spot with tail eastward

Alphonsus 1990 Feb 03 UT 18:00-18:23 Observed by A.C. Cook
(Frimley, UK, CCD video camera, seeing III-IV). At 18:06 W and
SE dark floor patches, equally dark, but at 18:10 and 18:23 the
W dark patch was the darker of the two?. Between 18:06 and 18:23
and a bright patch to the north of the central peak brightned
slightly wrt the its surroundings. However seeing conditions
worsened as the observing session progressed, and in view of
this the ALPO/BAA weight=1.
On 1972 Feb 23 at UT0010-0035 Fornarucci (Garfield, NJ, USA, 6"
reflector, x250, seeing=fair and transparency=3.5). Shading
usually visible west of it was not seen. Cameon comments that

On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector,
seeing II-III) noted that the south wall of Plato at the 11 o'clock
position, at the location of a cleft, was fuzzy on either side of the
cleft. There was also a deep red colour along the cleft and the outside
wall. The colour had gone by 22:40 though. All other parts of the rim
of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III)
sketched some obscurations at 22:03UT. At 22:08UT the red colour
reduced to a red line and vanished by 22:37. The south wall obscuration
varied in size and there was a possible obscuration at the 7 o'clock
position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and
M.Cook's observations. Detail inside the crater was sharp, but colour
oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km
away had atmospheric ripples affecting his observations. At 21:36UT G.
North described the south wall as odd in appearance and the terrain
south of this was lacking in detail - this was odd because elsewhere
Plato was nice and sharp. At 21:45UT though the north section of the
crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5.
The ALPO/BAA weight=3.
Sinus Iridum 2004 May 29 UT 20:44 Observed by Clementelli (Rome, Italy,
102mm diameter Vixen refractor 80-160x, sky conditions: clear, no wind)
"A blue/violet streak, lasting ~10 minutes was seen on the floor of
Sinus Iridum between crater Bianchini and Promontorium Heraclides. The
suspect TLP mybe an effect of instrumental achromatic aberration, but
there is the small possibility that the effect was real." A UAI
observational report. The ALPO/BAA weight=1.
Archimedes 1979 Oct 01 UT 20:57-21:00 Observed by Cook (Frimley, UK,

Aristarchus 1975 Dec 14/15 UT 17:05-00:30 Observed by Foley
(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 &
Brumder made it < Proclus" NASA catalog weight=4. NASA catlog

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 1981 Aug 11 at UT21:05-21:36 G. North (England, seeing=poor)
detected, in green light, a darkening on the floor of Plato. This
effect was not seen elsewhere. J-H Robinson (Teighmouth, Devon, UK)
detected on the SSE rim (inner and beyond) a triangle that appeared
hazy in a wide range of filters at 21:05UT. However at 21:36UT it was
only hazy in green and blue light. No similar effect was seen
elsewhere. The Cameron 2006 catalog ID=150 and weight=5. The ALPO/BAA

exposure 0.003 sec) saw on a computer monitor screen a flash
to far to the west of Herodotus and Aristarchus at the
location 54.53W, 23.5N. It had a duration of 0.5 sec and on a
brightness scale of 0 = night side of the Moon to 10 =
Aristarchus, ranked 7. Unfortunately they were not recording
at the time. As there was no confirmation observation and it
could be a cosmic ray air shower detection, the ALPO/BAA
weight=1
In 1934 Feb 25 at UT 18:30 Rawstron (USA?, 4" refractor, x250, S=6/12)
observed in Pico B: "A large patch of haze appeared & drifted off

Aristarchus 1989 Jul 15 UT 02:00-04:20 Observed by Manske, Weier,
Curtis, Keyes, Yanna, Norman, Knutson, Sullivan, Eichman and Radi (Carl
Fosmark Jr. Memorial Observatory, Madison, WI, USA, SCT C11) "Manske
initially observed a reddish tinge on the SE rim of Aristarchus. The
colour was present in different eyepieces. Two other pinkish tinge
areas were seen on the SE and NE rims. 4 of the observers did not see
colour. Independent confirmation was made by Don Spain (KY) and Smith
in LA. Full details can be found on the following web site:

Gassendi. 2023 May 02 UT 01:35-02:23. J. Albert (Lake Worth,
FL, USA - ALPO. 8” SCT via a 9mm ortho eyepiece. Transparency
magnitude 3 and seeing was 7/10) checked the crater without
filters as well as comparing with W25 red and W44A blue
filters using 226x. He saw no color on the SW part of the
crater floor or on the NW wall. Using the filters, however,
he did note that the high peak on the S wall was brighter in
blue than red. He tried this filter blink a number of times
because he had never seen this before in Gassendi, but the
result was the same each time. A colour image was taken
earlier at 01:21UT but shows not colour on S wall as it was
saturated. ALPO/BAA weight=2.
On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector,
x300) using an English Moonblink device found colour on the south west
part of the floor. Note that for the times given by Cameron, the Moon
was below the horizon from California - so possibly these are local
times and these times need to be correctly converted into UT? The
Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.
Gassindi 1966 Oct 25 UTC 22:30-23:10 Observed by Moore and
Moseley (Armagh, Northern Ireland, 10" refractor) and Sartory

ALPO/BAA weight=3.
On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector,
seeing=III) found the region around the cleft on the souther rim to be
out of focus - however atmospheric conditions were turbulent until
23:18UT. An unsual dark triangular region (long base against rim) was
seen to extend from the inner rim at 12 o'clock onto the floor for 13-
16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK)
found the south east to soth west to be obscured again, but not as
badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the
dark region had 2 white bands on the side and the south west wall was
blurred like it was on the 20th July - this time tough colour was not
present. There were also two light patches on the floor. Mosely
(Coventry, UK) observed the south wall at x120 and found the wall out
of focus at the 11 o'clock location. Through a yellow filter he saw a
"white mistiness: on the top of the southern rim and only the south
east cleft could be seen (no colour). By 22:40-23:00 the effect had
cleared up. No dark triangular patch was seen. When Marshall (Surrey,
UK) observed (22:30-03:00) nothing unsual was seen, though a sketch
provided shows a light patch on the floor located at 11 o'clock. All
observations, made by all observers had some atmospheric turbulence,
however trsnparency was good. The Cameron 2006 catalog ID=225 and the
weight=5. The ALPO/BAA weight=3.
Plato 1873 Nov 01 UTC 20:00? Observed by Pratt (England?) "Unusual
Appearance". NASA catalog weight=1 (very low). NASA catalog ID #182.
ALPO/BAA weight=1.
Aristarchus 1971 Mar 08 23:00-23:10 Observed by Lyttle (Northern
Ireland, 6" reflector, x98) "Suspicion of white spot W of N-S radial
band, slightly brighter than wall. Diam. @5-6km. Area affected by temp.
?Term. passed over it just 5h before. Gradual decline in brightness
over the 10m period." NASA catalog weight=1 (very low). NASA catalog ID
1288.
On 1788 May 17 at UT 21:00 Schroter (Lilleanthal, Germany, 210x
reflector) observed small depression, 1, near Aristarchus to be a
bright spot, similar to Cameron 1978 catalog ID report #45. The Cameron
catalog ID=48 and the weight=4. The ALPO/BAA weight=2.
NE of Philolaus 1948 May 20 UT 22:00-22:15 Observed by Baum
(Chester, UK, 4.5" refractor) A distinct reddish tint suddenly
appeared to the NE of the crater, and persisted for 15 min,
before rapidly fading away. NASA catalog weight=3. NASA
catalog ID #505. ALPO/BAA weight=3.
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

On 1978 Mar 21 at UT 20:57 an Unknown observer observed a TLP in
Aristarchus crater. The details for this report are still being looked
up in the archives. In view of the uncertain details this TLP has been
given an ALPO/BAA weight of 1.
On 1965 Jun 12 at UT > 00:00 an unknown observer (Porta?) reported that
the area of Herodotus and the Cobra Head expanded and the colour went
to rose. The next night the floor was normal. In filters, phenomenon
accentuated in orange. The cameron 1978 catalog ID=880 and weight=3.
The ALPO/BAA weight=2.
Aristarchus 1982 Jul 03/04 UTC 20:55-01:08 Observed by Foley (Kent, UK,
Seeing Antoniadi III) "Brightness variance" - CED 3.6-4.1-4.9. When the
crater was dark it had a slate-blue-grey interior. Moore found the
crater to be exceptionally bright and this was confirmed by J.D. Cook
(CED 3.8-4.1). The Cameron 2006 catalog ID=174 and weight=5. The
ALPO/BAA weight=3.
On 1982 Jul 03/04 at UT 20:45-01:08 J.D. Cook (Frimley,
Surrey, UK) found the Mare Frogoris area, north of Plato was
pink at 20:45UT. Saxton found flashes in Mare Frigoris and
near thye Alps. The Cameron 2006 catalog ID=174 and the
weight=5. The ALPO/BAA weight=2.
Interior craterlets could not be seen and some of the walls and
exterior features were fuzzy. ALPO/BAA weight=1.
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.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi
III seeing, 12.5" reflector) "Intensely bright craterlet south of central
peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed
the crater was highly luminous at 21:20, and surrounded by a blue halo that
had a darker blue band within it. This craterlet faded over time, and by 21:20
Moore considered that it was no longer prominent, by 21:22 Foley confirmed the
reduced brilliance, and by 21:30 Moore considered it to be perfectly normal.
Moore considers the nimbus effect to be normal. The Cameron 2006 catalog ID=

On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar
telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a
dusky dark gray area just north of Herodotus and just south of the
Cobra Head. The interior shadow on the east of Herodotus by comparison
wad black and distinct. No change was seen when viewed through a
rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA)
was observing at the same time but had better observing conditions and
could see detail in this region, suggesting that it was not a TLP.
There is no Cameron entry for this report. The ALPO/BAA weight=1.

Bullialdus 1979 Oct 04 UT 20:24-21:25 JH-Robinson (Devon, UK,
260mm Newt. x200 Seeing Antoniadi IV-V, Transp.=haze) observed a two
bright points on the south west floor patch to be brighter in red than
in blue at 21:12. The effect was still present at 20:36 but back to
normal by 20:43-20:48. Amery (Reading, UK) found a possible brownish
tinge on the west wall, though spuroius colour was present elsewhere on
the Moon. Foley found the WSW corner darkened in blue light. Cook found
pink on south rim of Bullialdus and Pedler found Bullialdus to be a
confused mass with bright and dusky spots and patches - no colour seen.

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

x286) observed that east of Lichtenberg were ëxtensive rosy areas"
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)
and Baum's (UK) 1951 observation. The colour was "ünmistakable" and
nothing to do with the atmospheric spurious colour. Other features were

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

the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively
bright spot appeared in the southern part of Mare Fecunditatis. The
spot looks sharper than the rest of the Moon and so might be a cosmic
ray? CCD images taken from Washington D.C. by A.C. Cook at this time,
do not show this spot, however exposures were at intervals of 0.25 sec

reflector, x75 and photography used, seeing 4/10 and the Moon's
altitude was 45deg) photographed Romer crater and recorded two adjacent
bright cigar shaped objects - these were the same size as an
observation made in 1987. Darling believes that these are ridges.

On 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a
darkening in the Cobra Head, Schroter's valley area of Aristarchus -
the best example that he had ever seen. The Cameron 2006 catalog ID=474
and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section
circular 1995 Oct, p125 and personal communication from David Darling
to the BAA on 6/6/1995. Note it is uncertain whether this refers to the
Clementine mission or to somebody who observed during the Clementine
mission, or somebody with that surname. Anyway if it is the Clementine
mission then the date is wrong - possibly the year should have been
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?
In 1930 Sep 15 at UT00:00 Vasilev (Russia) observed the following in
Alphonsus crater: "During SS there was a triangular spot nr. W. wall
until merging with shad. of wall (normal?) (date wrong as age is 3.2d &
should be @ 23d. 9/15/30 would be correct: aux. data for 15th". The
Cameron 1978 catalog ID=0. The Cameron 1978 catalog ID=398 and
weight=0. The ALPO/BAA weight=1.
