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

(Springfield, VA, 4.5" reflector, S=7) observed four glowing spots on
the Moon during a lunar eclipse (including Aristarchus). At 23:50UT
Aristarchus was an oval shape with no details seen. It had a ray
extending from the south west rim (normal). The north rim was slightly
blue and the south west rim very very slightly red. At 23:55UT it was
clearing and details showed. At 00:02UT it was clear. Sketches were
provided. Cameron comments that the colours fit Fitton's predictions on
spectral dispersion in our atmosphere from atmospheric inversions. The
brightness measued was 10+ and normal should be 9, and the plain is
4.5. The Moon's altitude at the LeCroy site was 45 deg. The Cameron

out of the north east rim of menelaus (Normal?). It appeared just
before the artea emerged and increased in brightness. At 23:58UT it
decreased and continued to do so. The north east edge of Menelaus
appeared very dark at the point that the ray was extending from SW edge
(a ridge there) and apperared to obscure features along its path
(Albedo=9). The Albedos of Manilius and Delambre were 8.5 at 00:05UT.

in Macrobius. His report is as follows: "Blinked Macrobius with Wratten
Filters Blue 38A and Red 29. Macrobius became almost invisible through
the Blue 38A and essentially the same as in white light through the Red
29. The interior of the crater was completely in shadow. The only part
of the east wall that was visible was an apparent high point still in
the sun and seen as a bright point of light. This faded into darkness
before 13:56UT. No sign of any illumination of the east wall crater
interior or the interior of the west wall was seen during the
observation period. The outer west wall was a rough looking,
complicated mix of deep shadow and illuminated sunlit terrain." The
observer concluded that there was not a TLP - although he did get a
filter reaction, this may have been due to the different densities of
the filters? ALPO/BAA weight=2.
