Triensecker Rille 1915 Jul 03 UTC 00:00? Observed by Markov (Russia)
"Several spots changed their shapes compared with Gordeenko's depiction
on 5/23/12 see #339; which cannot be explained by light variations."
NASA catalog weight=3. NASA catalog ID #356.
On 1981 Oct 18 UT 22:14022:16 M.Mobberley (Bury St Edmunds, UK,
14" Cassegrain, seeing variable, transparency misty) found that
the central craterlet on the floor of Plato was not visible,
despite it being visible under similar colongitudes on other
nights. Might be due to observing conditions, but observer
suspicous. At 02:08 the observer comments that the central
craterlet was ellusive, and at 02:42, though it is uncertain
whether they regarded it as suspicous still at this stage?
ALPO/BAA weight=1.
On 1891 Sep 23 at UT 22:00 Pickering, based at Arequipa, Peru, and
using a 12" reflector, saw in Schroter's Valley and the vicinity
"Varitions in vapor column. Drawings. Time estimated from given
colongitude)." Cameron 1978 catalog ID=272 and weight=1. ALPO/BAA
weight=1.
Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK,
10.25" reflector, x250, Wratten 44a and 25, seeing II) noted
that Aristarchus was surrounded by a dark area in the blue
filter. They did not regard this as a TLP at the time. However
because Aristarchus is surrounded by blue material in real life,
this should have been brighter? For this reason, despite the
observer regarding this as a negative TLP, an ALPO/BAA weight=1
has been applied.

Aristarchus and Cobra Head 1968 Jul 18 UT 00:50-01:30
Observed by Moseley & Corvan (Armagh, N.Ireland, 10"
refractor, x255) and by Moore (Selsey, England, 3" refractor,
x 120) "Distinct red glow & obscur. 1st at 0050 S. of C.H. &
same size. At 0052h saw color on S.wall of Aris. Both
persisted till 0100h then both (faded, then brightened, then
faded. Plato, Gassendi & Kepler checked with neg. results.
Obscured areas reached greatest extent at 0125h wgen it was
1/2 size of C.H. & SSE (ast. ?) of it. Moore was alerted to
it & saw it in blink, but not vis. at 0107-0220". NASA
catalog weight=5. NASA catalog ID 1085. ALPO/BAA weight=4.
On 1977 Nov 03 at 22:13UT P.W. Foley (Kent, UK, 11" reflector, x285)saw
some flickering in Gassendi (Clouds on limb - according to Csmeron?).
The Cameron 1978 catalog ID=18 and weight=1. The ALPO/BAA weight=1.
Closest parts of the Moon at Saturn appearing from
occultation were dull and hazy. Was this an effect of
the lunar atmosphere or a high haze and halo around the Moon?
Cameron's 2006 catalog extension gives this an ID No. of 3
and a weight of 1. The ALPO/BAA catalog weight is also 1.
Aristarchus 1973 May 27 UTC 01:09-01:56 Observed by Theiss (51N, 9.67E,
75mm reflector) "3 diameters of Aristarchus around its center: orange
bright area from 01:09-01:56" Ref: Hilbrecht & Kuveler, Moon & Planets
Vol 30 (1984) p53-61"
In 1919 Dec 19 at UT 04:00 Scholes (Huddersfield, England? USA)
observed near Littrow a conspicuous ink-black mark (North of Cape
Argaeus or S of Kittrow, The Cameron 1978 catalog ID=374 and the
weight=1. The ALPO/BAA weight=1.
Southern cusp obseved by H.Hill (UK) on 1984 Jul 25. Solar
Selenographic colongitude=232.6. Observer noted a dusky ill-
defined strip in Earthshine extending beyond the southern cusp
that appeared "atmospheric". 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.
On 1982 Aug 04 at UT19:25 Arkhipov (Ukraine). found that for 3 minutes
Aristarchus brightened. Cameron 2006 catalog ID=180 and weight=0.
ALPO/BAA weight=1.
On 1982 Aug 04 at UT19:25 Arkhipov (Ukraine). found that for 5 minutes
Copernicus flashes. Cameron 2006 catalog ID=180 and weight=0. ALPO/BAA
weight=1.
On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade
2045 reflector, x40, seeing=turbulent) detected flashes coming from
just north of the centre of Mare Tranquilitatis. Some of these flashes
were of a duration of seconds whilst others were several minutes.
Altogether ~20 flashes were seen, and not in the same place. "5 small
star-like points could be located - and there were lots of craterlets".
The spots were "lined up E-W at N of 10 deg latitude." Colour was not
visible on these nor variations. Apparently the observer had seen this
type of TLP before but had not reported them. The Cameron 2006 catalog
ID=323 and weight=2. the ALPO/BAA weight=2.
