it faded. Strong colour also seen by all observers e.g. green-blue to
violet. Report of observations written up in JBAA Vol 100, No. 3, p117

On 1983 Jan 29 at UT22:09 M.Mobberley (Sulfolk, UK, 14" reflector)

less (bright?) than Torricelli B's blueness. Other craters checked but

On 1986 Oct 20 at UT 03:30 Slager (Grand Rapids, MI, USA)
detected colour in Aristarchus, red on the south wall and a
blue "washed out gun metal colour on the "whole"inner north
wall. A 2nd observer confirmed the observation. Cameron
suspects that this is simply spectral dispersion. The Cameron
2006 catalog ID=288 and the weight=1. The ALPO/BAA weight=1.

measured that the brightness of the region around Toricelli B was 2.3
(high) and there was a slight blue colour. The Cameron 2006 catalog ID=
199 and the weight=4. The ALPO/BAA weight=2.
Herodotus 1972 Jul 27 UT 2250-2350 M.Brown (Hutington, UK)
thought that he saw a pseudo peak in the centre of Herodotus.
He could not decide if it was real or an optical illusion.

(Houston, TX, USA, 16" reflector, x130) "Intermittent blue color on SE

On 1983 May 31 at UT03:45-04:30 K. Marshall (Medellin, Columbia) noted
that the whole area of Aristarchus, Herodotus, and Schroter's valley
was both blurred and violet. There was hardly any detail seen inside
the crater. Herodotus could hardly be seen either and Schroter's valley
was totally unrecognizable. A sketch was supplied. The Cameron 2006
catalog ID=223 and the weight=3.
On 1964 Feb 02 at UT08:30-09:40 G.Reneau and B.Crowe (2.4"
refractor, x90)observed Ross D to be double. This was during a
time when observers were looking for a Ranger crash plume. The
Cameron 1978 catalog ID=799 and weight=1. The ALPO/BAA weight=1.
Something resembling a cigar shaped shiny object seen
on S rim - hanging over a smaller crater. It looked like a bright
aluminum can in the sun & cast a shadow onto the rim. The length
was 8-10 miles long x 1 mile wide at the central point.
It appeared tapered to points at both ends. Observer studied it
for several hours. S term. ~60-70miles away. Apparently not related
to topog. Alt. 8deg. Cameron 2006 Extension catalog weight=3.
ALPO/BAA catalog weight=1.
On 1895 Sep 07 an unknown observer (Lewis Swift?) observed a pale blue
segment on the upper limb - this was apparently confirmed by Faulkes
(Mem. BAA, 1895). Cameron says that this is probably 1895 Sep 08 at UT
06:00 as Sep 07 is local time. She also infers that "upper limb" is the
southern limb and that Swift was at the Lowell Observatory, Flagstaff,
AZ, USA. The Cameron 1978 catalog ID=285 and weight=5. The ALPO/BAA
weight=2.
Plato 1975 Jun 28/29 UT 23:00-01:20. Foley (Wilmington, UK, 12"
reflector, seeing, III, good clarity transparency). At 23:00,
00:30, and 01:15 blue was seen on the inner wall:floor southern
boundary, and red on the corresponding northern floor:wall
boundary. However by 01:20, blue was now on the S-NW floor:wall
boundary, and red on the NE-SE floor:wall boundary. Atmospheric
spectral dispersion existed in many regions, but did not change
like the colours in Plato. Similar appearance craters such as
Grimaldi, Schickard, and Riccioli, were checked for a similar
change in colour, but no change was noticed in these. ALPO/BAA
weight=1.
Aristarchus 1975 Nov 15 UT 06:34 Observed by Rule (Edinburgh, Scotland,
4" reflector x36) "Blue patch in crater (similar to many of Bartlett's
obs.?)" NASA catalog weight=2 (low). NASA catalog ID #1383.
Aristarchus 2004 Dec 02 UT 01:55-02:45 Observed by Brook (Plymouth,
England, 60mm OG x120) "Fluctuation in the brightness and definition of
A of about 1/4 to 1/2 minute period. Rest of field unaffected. Checked
for cloud wih naked eye during fades - negative. Checked for misting
and tear salt on eyepiece by shifting A around the field - negative."
BAA Lunar Section report.
Aristarchus 2004 Dec 02 UT 03:00 Observed bt Michael Amato (West Haven,
CT, USA, 127mm Maksutov, x123) "The brightness variation (as seen by
Brook earlier) was very apparent. One thing never seen before by Amato
was a thin short bright ray that extended out in the opposite direction
as Aristarchus bright ray". The higher the Moon climbed in the sky the
more obvious this short thin bright ray became. An ALPO report.
Plato 1975 Jun 29/30 UT 23:05-00:30. Foley (Wilmington, UK, 12"
reflector, seeing, III, good clarity transparency). At 23:05,
blue was seen on the inner wall:floor southern boundary, and red
on the corresponding northern floor:wall boundary. However by
00:30, blue was now on the W floor:wall boundary, and red on the
E floor:wall boundary. Atmospheric spectral dispersion existed
in many regions, but did not change like the colours in Plato.
Similar appearance craters such as Grimaldi, Schickard, and
Riccioli, were checked for a similar change in colour, but no
change was noticed in these. ALPO/BAA weight=1.
Marcus Price (Camberley, Surrey, UK) noted that Aristarchus
was extremely bright. A 6" reflector was used. The Cameron
2006 Catalog ID is #98 and the weight is 1. The ALPO/BAA weight
is 1 too.
On 1987 Oct 13 at UT14:00-17:00 J. Moeller (Kirkville, NY, USA,
6" reflector) observe and 10x70 binoculars) noted that
Aristarchus was brilliant in the sky and the most striking
feature on the lunar surface (2-3x brighter than Tycho). It
appeared as a hazy white cloud at first. The effect lasted for 3
hours. The Cameron 2006 catalog ID=309 and the weight=1. The
ALPO/BAA weight=1.
On 1974 Jun 12 at UT0256 an unknown observer noted a dark blob on the
northern edge of the floor of Pitatus crater.
Aristarchus 1980 Aug 04 UT 11:40-11:53 Observed by Jean
Nicolini (Campinas, SP, Brazil, 6" reflector and 12"
reflector) "Red glow seen on SE exterior of Aristarchus".
ALPO/BAA weight=2.
Spitzenberg Mountains 1980 Jul 06 UT 02:05-02:26 Observed by Madj
(Newsome, Huddersfield, UK, 70mm OG, Seeing started as I and ended up
as IV) "Obscuration seen near Spitzenberg Mountains" BAA Lunar Section
Report.
Grimaldi 1998 Mar 22 UT05:15-06:00 S. Beaumont (Windermere, UK,
127mm rich field refractor, seeing III, transparency Good)
observed that the northern half of Grimaldi seemed much lighter
than the southern half. She comments that she has seen this
before in last quarter phases, but it was really quite marked
how lighter the northern half was on this occasion. The ALPO/BAA
weight=1.
Aristarchus 1976 Oct 18 UT 07:42 Observed by Bartlett (Baltimore, MD,
USA, 4.5" reflector and 3" refractor, S=3, T=5) "Inner E. wall 6 deg
with very large EWBS at 8deg. No viol. color anywhere & floor was gray
at 4 deg (very low). C.p. is only 8 deg. At base of c.p. between peak &
advancing shadow a very faint but definite red glow was seen. It was
also seen later in the 3" refr. Was confined to W.base of peak & no
color on E. base tho. carefully searched for. This red glow was unique
in his experience of 28 yrs. His obs. thru. col. 223deg saw nothing
more unusual." Cameron 1978 catalog weight=4 and ID #1455.
Elger 1970 Aug 22 UTC 02:35-02:43 Observed by Merosi (Pecs?, Hungary,
6" reflector x150). "Brightening in dark beyond term., 3deg size, 1.5x
size of Elger. Not variable for 5 min. but decreased & became in-vis.
after 0243h. No high peaks there." NASA catalog weight=3 (average).
NASa catalog ID #1275.
Four bright spots intersected terminator on dayside
only. Two of the spots were identical. Reciprocating
motion of the terminator in five or six minutes
between pairs touching in turn. The terminator in
Mare Fecunditatis was still. Similar phenomena seen on
Jupiter's satellite once. Cameron thinks that the
1774 date in the Middlehurst catalog is wrong and should
be this one.
