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.
On 1969 Jul 19 at UT 1845-18:47 Pruss and Witte (Bochum, Germany, 6"
refractor x36 and binoculars) saw brightenings in the north west wall
of Aristarchus for 3-7 seconds of about 1 magnitude over the
background. From orbit at UT 18:46 the Apollo 11 crew Armstrong,
Aldrin, and Collins (in orbit around the Moon and using the naked eye)
were asked to take a look at Aristarchus after Earth-based reports of
TLP activity. Armstrong reported (after the solar corona had set, on
the night side) that probably Aristarchus "to be considerably more
illuminated than the surrounding area. It just has - seem to have, a
slight amount of flourescence to it". Collins reported a moment later:
"Looking out on the same area now. Well at least there is one wall of
the crater that seems to be more illuminated than the others. I am not
sure that I am actually identifying any phosporesecence, but that
definitely is lighter than anything else in the neighborhood". Houston
then asked if the crew could detect any colour and if the inner wall
was the inner or outer part? Aldrim commnted that it was the inner
wall and Collins mentioned thatno colour was incolved. The Cameron 1978
catalog ID=1165 and weight=5. The ALPO/BAA weight=3.
On 1969 May 21 at UT 20:00-21:00 Brandli and Germann (Switzerland, 6"
refractor) observed a slow orange-red blinking on the surrounding area
of Aristarchus. It was seen less markedly the next night. Wald (Zurich,
Switzerland) noted at 20:30UT that the crater was pink (Confirmation
says Cameron) - this was during the Apollo 10 watch. The cameron 1978

Mons Piton 2022 Aug 04 UT 19:41-20:10 T. Smith (Codnor, UK,
16inch Newtonian, x247, Seeing IV) mountain was very bright
and red around its eastern slopes. An examination of the
bright and contrasty Proclus crater revealed that to be
relatively colour free compared to Piton. An examination of
other features, north and south along the terminator revealed
some tinge of coloiur but not as strong as on Mon Piton. Mons
Piton examined with a yellow filter at 19:50 and still showed
red along the eastern side, other features along the
terminator had no colour through the filter. Video images by.
A.Cook (Newtown, UK) made earlier at 1929 & 19:40 UT, (in the
SWIR (1.5-1.7 microns) did not reveal Mons Pico as especially
bright - but resolutioin was poor. A friend of Smith, phoned
up the next day to say that they saw a mountain on the limb
exhibiting red on the 14th August. Probably the redness was
due to atmospheric spectral dispersion as the Moon was low,
and it was especially visble on Mons Piton as this is an
exceedingly contrasty object on the terminator. ALPO/BAA
weight=1.
Theophilus 1969 Jul 21 UT 19:30-21:45 and 21:00-22:00 Observed by Fox

On 1991 May 21 at UT05:30-06:15 J. Green (Orangevale, CA, USA, 11"
reflector) photgrapphed a broad bright band stretching east and north
of Cassini crater in 3 exposures taken 10 minutes apart. This
photographic sequence shows a gradual widening towards Cassini and by
the 3rd exposure the band is touching (and then obscuring) Cassini. A
"fan" was visible in the north east and WSW directions, later this was
seen as rays and this was even seen in the view finder of the camera.

College, Whittier, CA, USA, using a 10" f/8.2 Newtonian
reflector, x78 & x208, seeing 5-6, transparency 2-0) observed a
ridge obscured SSW of Ross D. No drawing was made, only a
written description. "Ridge not visible near crater; possible
white patch 1/3 Ross D diameter" The ridge is the wrinkle ridge
extending NNE from Ross D, a well established often visible
feature. Harris comments that this was not one of the better TLPs
seen near Ross D, and there were no independent observers,
neverless he was ceratin of this being a TLP, and it was
consistant with other activity seen near this crater between 1964
and 1970. Cameron 1978 catalog ID 891 and weight=3. ALPO/BAA

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

On 1983 Aug 22 at UT 05:44-06:33 D. Louderback (South Bend, WA, USA,
3"refractor, x150) found the brightness of Aristarchus (diffuse white
patch) to be 7 to 7.5 but apparently it is normally 8-8.5, so fainter
than normal. Another brightness reading found "brightening then nearly
extinction at S. wall similar to changes seen on Eimmart before.
Watched fluctuation compared to Cobra Head, they were similar but more
pronounced at Aristarchus" especially in blue light compared to red
(although there was a little brightness in red). Timings of these
fluctuations were 7sec, 7sec, 9-10sec and 9-10sec. The latter two might
have been seeing related as the crater enlarged up at these times. The
observer felt that the Cobra Head appeared fainter than the previous
year and had faded during the second set of brightness measurements.
Cameron 2006 catalog ID=227 and weight=3. ALPO/BAA weight=2.
On 1983 Aug 22 at UT05:44-06:33 D. Louderback (South Bend, WA, USA, 3"

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.

On 1985 Sep 28 UTC 20:54-23:52 P.W. Foley (Suffolk, UK) found (actually
before 20:54 UT) brightness variance in Torricelli B. J.D. Cook
(Frimley, UK) observed a brief blue coloured patch somewhere in the
Torricelli B region, but could not pin it down precisely. At 22:50UT
M.C. Cook (Frimley, UK, 30cm reflector, seeing III - occasionally V,
transparency moderate to good) Found the crater to have an elongated
appearance (in SSW-NNE direction) in white light, similar to the
previous night. A bright elongated spot was seen on the NNE floor,
close to where the wall should be. Not able to define the rim. There
was a very dark surrounding area to the crater, similar to what it was
on the previous night (roughly 1/4 brightness of Censorinus). 23:04UT
brighter in yellow, then red, then blue. At 23:10 it was seen that blue
filter dulled the crater - this was odd because both Censorinus and
Proclus were brighter in blue, which is what he would normally expect.
At23:15 UT Censorinus was brighter in blue, then yellow then red
filters and some orange spurious colour seen to the south of
Censorinus. At 23:23UT no spurious colour seen on Proclus or
Censorinus. 23:46UT Torricelli B elongated as before, but a very faint
ray might have been seen to the south west of the rim. This report is
not in the 2006 Cameron catalog. The ALPO/BAA weight=3.

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.
On 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a
darkening in the Cobra Head, Schroter's valley area of Aristarchus -
the best example that he had ever seen. The Cameron 2006 catalog ID=474
and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section
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?
Aristarchus 1964 Jul 31 UT 02:00-02:23 Observed by Bartlett
(Baltimore, MD, USA, 5" reflector x180) "Deep ravine on E.glacis
interrupted midway of its length by apparent break just below

Triesnecker 1966 Jul 10 UTC 02:00-02:15 Observed by Allen (Cambridge,
England) and other observations by Corralitos Observatory (Organ Pass,
NM, USA). Described in NASA catalog as: "Faint illum. of a ridge in
shadow; faded quickly (in BAA judged dubious). Not confirmed by
Corralitos MB." 12?" refractor (x280) used at Cambridge and at
Corralitos 24" reflector. NASA catalog weight=1 (very low). NASA
catalog TLP ID No. #956.
On 1996 Feb 12 at UT 07:30-08:27 J.Sandel (Caycee, SC, USA)
noted a contrast effect inside Tycho at sunset. At 07:30UT there
was a slight, but definite illumination of small areas of the
crater floor west of the central; peak. Also seen by T. Ferrel
(Lawrenceville, GA, USA, SCT C8). This was oval in shape and
gray in colour - Ferrel noted some diffuseness. It brightened
over 30 minutes. At 08:11UT a definite brightness fade noted in
Tycho's central peak. The crater floor had increased
illumination of entire crater floor. ALPO/BAA weight=3.
On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52"
reflector) observed that central craterlet in Plato was
unusually bright and shows up as a bright white spot on his
sketch - though this might have been artistic license in his
sketch. His written notes refer to the unusual lack of a rim
(especially the northern part) to this craterlet.
The ALPO/BAA weight=2.
Aristarchus 1970 Jul 26 UT 15:00? Observed by Sekiyuchi (Tokyo, Japan,
36" reflector) "Polarimetric and photoeletric anomalies on Moon" NASA
catalog weight=5. NASA catalog ID #1268. ALPO/BAA weight=5.
On 1979 Sep 16 at UT 08:00-09:00 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x62-x97, clear, but Moon at low altitude) detected
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
by 6x) for a few seconds. Cameron thinks that these are related to
moving clouds on the Earth's limb e.g. mackeral sky. Cameron 2006
catalog ID=69 and weight=1. ALPO/BAA weight=1.
Herodotus 1969 Aug 09 UTC 03:00-04:03 Observed by Gomez (Sabadell,
Spain) desribed in NASA catalog as: "Bright point on SE wall at 0300h,
gone at 0322h. Brightened in blink device (Eng.) at 3:30:50, 3:41:36,
04:03:21" 12" reflector x155,x258,x388. Average weight=3 in NASA
Catalog.
ALPO/BAA weight=2,
James Short, Dr Harris and Mr Stephens saw initially a streak of
light on the shadowed floor of Plato. They were not expecting to see
any light to reach the floor. Shortly afterwards they saw a second
streak of light parallel to the first and this shortly divided
into two. Gaps in the mountains were found for both streaks,
but they were unable to understand why one of the streaks divided
into two. Cameron's 1978 assigns this TLP an ID of 20 and a weight
of 5. The ALPO/BAA catalog assigns a weight of 1.
