On 1981 Feb 10 at UT21:46-21:49 P. Madej (Huddersfield, UK) found a 2nd
mag star-like point on the north east wall of Aristarchus crater. M.
Price (Camberley, UK) at 21:46 and 21:49. North (UK) detected flashes
from the central peak. Foley saw Aristarchus as a "translucent glow".
Moore, Pedler and Ratcliff could not find Aristarchus. Earlier though
Amery (Reading, UK) had found Aristarchus to be sharply defined.

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

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.
Tycho 2003 May 09 UT 21:04 Observer Brendan Shaw (UK) "CCD

Section member (Southam, Warwickshire, UK) found no detail on the floor
of Autolycus, despite there being plenty of detail on the floor of
Aristillus crater. According to Foley, there should be some detail at
this stage of illumination. Grego reports that the observation was from

reflector, x159, S=7/10) observed similar light conditions to 1989 Jul
15. At 02:00 he observed pink on the south west wall of Aristarchus
crater. At 01:24UT the Aristarchus ray was yellowish, however the
entire Moon had a grey-yellow tinge of colour. Chromatic aberation was
observed at 01:56UT. By comparison Gassendi was checked and had no

On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in
Gassendi - some obsevers detected colour, others did not. P. Moore did
not notice anything unsual earlier at 18:50-19:00, though his seeing
was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing
was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also
reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did
however notice a small reddish spot to west of central ridge, but by
20:30UT the colour was less obvious, but the spot was back again at
20:45, but not easily seen at 21:00 and gone completely by 21:45UT.
N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red

On 1965 May 12 at UT 19:10 E. Penzel (Rodewisch, East Germany) was
taking a sequence of images during the impact of the Soviet Lunik 5. He
detected a tens of km scale elongated cloud after the impact over a
duration of 9.5 minutes. However there are differences between the
images elsewhere on the Moon, possibly due to different exposures or
some other effects and it is not 100% sure that what he detected was
impact debris/cloud?. The ALPO/BAA weight=3.
On 1964 Jun 21 at UT 21:18 Lipskii and Pospergelis (Shternberg State
Ast. Institute, AZI-2" reflector (Cass.) observed Aristarchus:
"Polarization meas. with electron polarimeter. Plane of polariz.
rotated 2deg fr. the adjacent areas. They interpret it as some
scattering medium over the crater. (Source gave date as 6/31/64,
misprint =21st?)". The Cameron 1978 catalog ID=820 and weight=5. The
ALPO/BAA weight=4.

On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK,
12" reflector, x200, seeing=II) noticed in the area south east of
Manilius that it was brighter in red light than in blue light at
20:15UT whereas 1 minute later it was the same brightness in each
filter. The effect reappeared at 20:21UT and was particularly strong at
20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was
of high reflectivity in white light and was bright in red at 21:15UT,
thougjh the south east area stopped giving a colour reaction at
21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT
however at 23:55UT it was surrounded by a transient white ring that
varied in visibility in an irregular way. Foley found Manilius B had a
vivid blue interior and in blue light the ring was black. and not at
all seen in red or white light. The CED brightness measurement varied
from 1.9 to 2.4. All other regions observed were normal in brightness.
Violet was seen on the west wall of Aristarchus though. M.Price
(Camberley, UK) found a possible blink in Manilius B but was observing
under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5.

accentuated in orange. The cameron 1978 catalog ID=880 and weight=3.
The ALPO/BAA weight=2.
On 1995 October 6 at UT 21:30 R. Lena (Rome, Italy - a UAI observer,
11.4cm reflector) saw 4 or 5 flashes from Herodotus crater. Light
intensities (mag?) ranged from 9 to 8 and they were brighter through a
red filter. There is no 2006 Cameron catalog entry for this observation
- it has come from the UAI web site. The ALPO/BAA weight=3.

On 1985 May 02 at UT 20:20-20:38 J.D. Cook (Frimley, UK) noted at 20:20
found the south rim (and just outside) to be blurred in appearence and
there was also a hazy shadow inside the crater. M.C. Cook found a
"break in clarity in break on S wall". Miles (UK) also found the south
wall blurred in appearance and Foley (Kent, UK) noted that the area was
featureless and the 2 craters positions at 1 o'clock high up on the
inner wall were obscured", although just north of these was sharp
detail. Foley also recorded that the shadow on the east wall was
opaque"and that thye inside of Aristarchus was slate/blue in colour and
dull, however by 20:28 the crater had brightened by 0.4 steps on
Foley's CED device and the missing craterlets were visible again. Jean
(Canada, 4" refractor) observed a rose colour intermittently (UT 1948-
20:58) - however Cameron suspects that this is chromatic aberation.
The Cameron 2006 catalog ID=269 and the weight=5. The ALPO/BAA
weight=3.
On 1988 Sep 23 at 19:40-19:55 & 20:36-20:41 G. North (760mm
Coude Rrefractor, x250, Royal Grenwwich Observatory,
Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55
image very unsteady. All seems normal in other crtaters with
the exception of Arcimedes. Much of the rim seems indistinct
apart from a 1/4 length of the west rim. Strongly suspected
that this was due to a combination of seeing and illumination.
UT 20:02-20:06 - checked the area with a lower magnification
10" Astrographic Refractor - the crater seems more normal, so
suggesting that the theory was correct. 20:36-20:41 returned
to the 30" reflector, and the crater appeared similar to the
start of the session. This is almost certainly not a TLP, but
it would be helpful to have some images or sketches to check
this theory out. Weight=1.
On 1987 Mar 13 at UT02:00-03:00 De Groof (Belgium, 8" reflector x150,

On 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW,
Australia, 8" reflector, x100, x160, S=III) observed a bright star-like
point on the western (IAU) edge of Mare Tranquilitatis (x100) that
appeared unlike any other crater and a check of the location revealed
no suitably bright crater in that region (from a map?). Changed to a
higher power (x160) and it was still there, but not as conspicuous.
Observer thinks that this may have been due to the Moon's low altitiude
(16 deg) and the seeing. At 18:35 he compared it to the brilliant
crater Proclus and found the star-like point to be 75% of the
brightness of Proclus. Ken Wallace (Australia) had been taking photos
and observed the object at 17:37.5UT. The object gradually faded over

On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK,
seeing=IV-V, transparency=good, spurious colour seen) found 2
bright pathces on the east rim on alternate sides of a bright region.
The band from the central 16km wide region was dark on the east side.
Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be
not as bright as normal, apart from the band that Mobberley found (1
hour later). The dark regions were a murky green colour (bright through
green, blue and yellow filters and dark through red and orange
filters). Cook (Frimley, UK, transparency=excellent, CCD camera used)
found a bright "bulge"on the eastern side. Apparently data suggests
that the band was brighter in red than in near IR light. Cook's
calibrated brightness measurements suggest that there was no change in
brightness over the crater with time. Two other bright points were
seen: one at the Cobra's Head and another half way between the east rim
of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87
(near IR) and combined Wratten 29 and Wratten 87 were used. In the red
Wratten 29 filter the brightness falls at22:20 at Shroters valley and
then rises in the bright ray. They return to normal at 22:30UT. There
was however a lot of measurement noise from the brightness readings of

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

England) "Brilliant in blue & green filters. Didn't seem to be as clear
as other craters." NASA catalog weight=4 (good). NASA catalog ID #598.
Tycho 1990 Dec 10 UT 11:03-12:49 Observed by Darling (Sun Prairie, WI,
USA, 12.5" Newtonian, x63) "Nebulous patch seen where the central peak
should have been in the 90% shadow filled crater. The nebulous patch is
seen to vary in size and a star-like point is seen inside it briefly
for 1 sec. The nebulous patch was a bit like what one expects from a
close-up view of a cometry nucleus. A sketch and an image can be found
on the following web site:

Report.
On 1987 Oct 17 at UT17:00-18:00 (in daylight) J. Moeller (Kerkville,
NY, USA, 6" reflector, x80-x135) observed that Aristarchus had a long
trench-like feature going off to the north west limb. On the 18th this
feature was more cloud like, "bright white and opaque. (Trench =
Schrotes Valley? Similar to 10/13/67)". The Cameron 2006 catalof ID=311
and the weight=1. The ALPO/BAA weight=1.
In 1835 Dec 22 at UT17:00-18:30 Piazzi-Smyth (Edinburgh, UK) at 18:30UT
observed near Aristarchus a bright spot of magnitude 9-10 and at
17:00UT Baily (England) observed a star-like point, in Aristarchus.
The Cameron 1978 catalog ID=113-114 and the weight=5. The ALPO/BAA
weight=3.
On 1867 May 06 at UT 20:00-22:00 Tempel (Germany?) and Flammarion
(France?) observed Aristarchus to be a reddish-yellow beacon-like
light. Left (E. ?) side of crater very bright luminous point. The
Cameron 1878 catalog ID=152 and weight=5. The ALPO/BAA weight=4.
On 1965 Dec 27 at UT Bornhurst (Monterey Park, CA, USA, 10" reflector)
and (Harris (Whittier? CA, USA, 19" reflector?) observed brightening of
Aristarchus in Ashen light. Cameron says that this is an independent
confirmation? The Cameron 1978 catalog ID=918 and weight=4. The
ALPO/BAA weight=2.
On 1982 May 26 at UT 20:25-20:40 Kalauch (Berlin?, Germany, 9"
refractor, x60, T=1(best) and scintilation=2) found Aristarhus to be
"very visible" in Earthshine - which was very clear. At 20:25 UT
Aristarchus was seen to blink irregularly and then it attained
magnitude 7 (red). Telescopes and eyepieces were changed but did not
effect the appearance. It disappered at 20:40UT. Cameron 2006 catalog
ID=168 and weight=2. ALPO/BAA weight=2.
On 1867 May 07 at UT 20:00-22:00 Tempel (Germany?) and Flammarion
(France?) observed Aristarchus to be a reddish-yellow beacon-like
light. Left (E. ?) side of crater very bright luminous point. The
Cameron 1878 catalog ID=152 and weight=5. The ALPO/BAA weight=4.
Barker's Quadrangle (26W, 34S) 1949 Mar 03 UT 20:00 Observed by
Moore (England, 12" reflector) "Whole area hazy. (in Capuanus?
see Wilkins and Moore, The Moon, p124) (It may not be this
identification as 3 of 4 obs. are in dark, some nr. FQ so
doubtful it could be seen)." NASA catalog ID #516, weight=4.
ALPO/BAA wight=2.
In 1909 May 23 at UT 18:00? an unknown English observer observed a
bright spot east of Picard. The Cameron 1978 catalog ID=330 and the
weight=1. The ALPO/BAA weight=1.
On 1986 Mar 15 UT 19:51-19:55 A. Cook (Frimley, UK, Naked Eye
and 12" reflector, x60, seeing IV, transparancy poor)
observed a naked eye flash at 19:50.5 UT in the Mare Nubium
area. The flash was white in colour and lasted not longer
than 0.5 sec and was about magnitude 2 at most in brightness.
There was no rise or fade associated with this flash. Upon
checking the area with the telescope, the observer reproted
seeing a faint fuzzy small patch that came and went over
several seconds in the same general area - but this may have
been due to the seeing conditions and/or glare from the
bright side of the Moon. The patch area was about the same
size as Aristarchus, i.e. approx 40 km across. Note however
that observing conditons were too poor that night to see
Aristarchus. At later observing sessions from 20:30UT
onwards, the patch was not seen. The ALPO/BAA weight=3.
On 1990 Jan 01 at UT 16:55-18:45 H. Miles (Cornwall, UK) observed that
Aristarchus was seen in Earthshine at 16:55UT before the limb (was
visible in Earthshine?). "1705 Aris>>1723 fading 1727 > again." Then:
"1740 Aris << and just visible at 1845". Apparently Foley suspects that
Aristarchus had brightened up before 16:55UT (shwen H. Miles started to
observe) and then gradually retruned to normal. The Cameron 2006
catalog ID=385 and the weight=0. The ALPO/BAA weight=1.
On 1969 Oct 16 at UT 00:00-00:30 Celis (Quilpue, Chile, 3" refractor,
x60, seeing=very good) observed brilliant points at 8.5 magnitude in
Aristarchus. This was not seen the next night or the one after, nor
after 5 days age. The Cameron 1978 catalog ID=1204 and weight=1. The
ALPO/BAA weight=1.
A faint white pinpoint flash seen and also in the same position
a whitish glow around the crater. No futher flashes seen after the
first one. From UT2117-2130 the glow was still visible but faded
making it more difficult to locate. When Foley observed he found
Aristarchus not very visible in Earthshine, despite Plato, Grimaldi,
and several other features being visible. Both observers used
12" reflectors. Cameron's 2006 catalog Extension ID=124 and
weight=0. ALPO/BAA weight=3.
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.

On 1994 Jun 14 UT 21:45-22:00 G.Rogers (Crendon, UK, 3" Zeiss
refractor, sky conditions perfectly clear) reported seeing three
very large whitish clouds against the Moon. The strongest seemed
to "stem" from the vicinity of Santbech crater (crater
identified the next day from an atlas), and was a milk chocolate
colour near the stem. The other two large clouds were to the
north - in the general area of Mare Fecunditatis and Mare
Crisium though perhaps slightly further west and in contact with
the terminator? The effect was confirmed (independently) by 4
other observers using the same telescope. The telescope was
moved but the clouds remained in the same position over the
Moon. This report comes from The Astronomer Jan 2013 p 230.
