Southern cusp obseved by H.Hill (UK) on 1985 Sep 12 UT0435-0455.
Solar Selenographic colongitude=241.3. Observer saw an extremely
attenuated cusp extending well beyonf the Moon's prime meridian.
There were also dusky ill-defined stips along the Earthlit limb
nearby. Note that this is almost certianly not a TLP but is
worth checking out if the libration and solar colongitude is
similar, just to verify that this is what the Moon normally
looks like. ALPO/BAA weight=1.
Knopp of Paysandu, Uruguay on 1885 Feb 21 at 23:00-23:30? UT saw red
patches in the crater. Reddish smoke or mist. The observer says several
others had seen a star like point there that night. Cameron's 1978
catalog ID=348 and weight=4. ALPO/BAA weight=3.
Plato 1964 Nov 14 UT 01:00? Observed by Bartlett (Baltimore,
MD, USA, 4" refractor?) "Peak on E. wall brilliant white,
strong blue band at inner base; on S. wall was a small, bright
red spot." NASA catalog weight=4. NASA catalog ID #864.
ALPO/BAA weight=3.
La Hire 1887 Feb 02 UTC 20:00? Observed by Klein (Cologne, Germany, 6"
refractor) "Intense yellow streak that cast shadows around neighboring
features". NASA catalog weight=4 (good). NASA catalog ID #255.
Scarcely a trace of nebulae tonight. As long as to June 10 at
2000UT? A little blackness remained. (P. Moore thinks it
was a LTP, WSC it was a permanent feature?) Drawing. Seen
by Nevelius Emmett, J. Boroughbridge, England. The 2006
Extension catalog by Cameron assigns an ID No. of 4 and a
weight of 1. The ALPO/BAA weight=1.
Aristarchus 1963 Oct 30 UT 01:50-02:15 Observed by Greenacre and
Barr (Flagstaff, AZ, USA, 24" Clark Refractor) observed 2 ruby
red spots - one just to the SW of the cobra's Head and the other
on a highland area east of Vallis Schroteri. A pink colour
formed coverting the SW rim of Aristarchus. Effects present with
or without Yellow Wratten 15 filer. Similar effects checked for
elsewhere on other craters but not seen. So presumed not to have
been due to chromatic aberation or astmospheric dispersion.
Effecta not seen in 12" refractor, but this may have been a
resolution issue. The NASA catalog ID No. is #778. The NASA
catalog weight is 5 (highly reliable). ALPO/BAA weight=4.
Aristarchus 1963 Oct 30 UT 05:00-08:00 Observed by Greenacre and
Barr (Flagstaff, AZ, USA, 24" Clark Refractor) a violet or
purple-blue colour formed beyond the NW of Aristarchus. ALPO/BAA
weight=2. This followed an earlier observation that night of two
red spots and a pink glow.
On 1981 Nov 10 at UT 07:54-08:22 D. Louderback (South Bend, WA, USA,
3" refractor and filters, seeing=2-3 and transparency=5) observed a
blue light at the Cobra's Head, near Aristarchus, that fell back down
to a normal brightness of 7. although the west wall (his point D) went
down to 6.5 (this was 8 back on Oct 5). The Cameron 2006 catalog ID=158
and the weight=3. The ALPO/BAA weight=2.
On 1981 Oct 12 at UT 00:00?(?) B.W. Chapman (12cm refractor,
Seeing II, transparency poor, Kingston-Upon-Thames, UK) found
that Mons Pico was brighter in red light than in blue.
Aristarchus for comparison was the same brightness in both
filters. ALPO/BAA weight=1.

On 1976 Feb 14 at UT23:35-0053 LeCroy (Springfield, VA, USA, 4.5"
reflector, x75, S=6 and T=4.5). A blue haze was seen on the east side
of Aristarchus and red haze on the west side. At 00:00UT details were
more clear and at 00:24UT Aristarchus and Herodotus, were seperated. At
00:34UT colours were gone. At 00:35UT blue was on Aristarchus and the
area was bright, but was black in a red filter. At 00:53UT the features
were clear and the colour gone and the brightness had decreased to 9.
Cameron comments that the colour was not due to temp. inversion because
of being dark in the red filter, implying a medium). The Cameron 1978
catalog TLP ID is 1428 and the weight=1. This is an ALPO report. The
ALPO/BAA weight=1.

x260) saw at 01:25UT an unmistakable red-orange glow on the south and
south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected
it easily. At 01:33UT the colour was barely visible. No TLP alert was
issued because the souther edge of Mons Pico also exhibited a hint of
colour, and anyway the seeing conditions were poor. Despite this no
other features revealed colour. The Cameron 2006 catalog ID=446 and the
weight=0. The ALPO/BAA weight=1.
On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector,

the best example that he had ever seen. The Cameron 2006 catalog ID=474

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?

was a slight, but definite illumination of small areas of the
crater floor west of the central; peak. Also seen by T. Ferrel

gray in colour - Ferrel noted some diffuseness. It brightened

four new features that he had not seen before in Earthsine in
comparison with what he saw on 16 Jul 1979, this time in the southern
part of the Moon. pin-point flashes were seen within these bluish
areas. Each time a flash occurred the gas clouds brightened (sometimes

moving clouds on the Earth's limb e.g. mackeral sky. Cameron 2006
