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.
On 1997 Jul 25/26 at UT 23:00-00:00 S. Fox (Dundee Tayside, Scotland,
UK, 15cm f/5 reflector with x4 Barlow). A series of photographs were
taken that show a glow just beyond the terminator, near to Callipus
crater. Almost certainly this is lens flare from the Barlow lens. The

Some variability in brightness noted. With the Kodak Wratten
25 and 38A filters there was little or no increase in contrast with the
red filter, but with the blue filter there was a great increase in
contrast of the brighter areas of the crater - the crater floor and
patches of lighter material, especially at the north end. The remaining
areas were supressed with the Blue 38A. ALPO/BAA weight=3.

Observer noted a bright spot on the interior west wall that seemed
brighter than what they would have expected. unfortunately the precise
time of this observation was not recorded so the moon-rise and
midnight UT values are used to place a limit on the time of
observation. Images by Shaw taken at UT 1754, 18:45 and 23:13
do not exhibit the effect.

Plato 1870 May 12 UTC 22:00 Observed by Birt (England)
"Extraordinary display of lights. Says not effect of sunlight"
However an article by Nigel Logshaw in the Feb 2014 LSC suggests
that it was probably just normal fine scale spots and streaks on
the floor of the crater. NASA catalog weight=4. ALPO/BAA weight=

Plato 1986 Dec 13 UT 20:30 Observed by A. Cook (Frimley, UK,
seeing III) North East quadrant of Plato the crater was blurred
and ill-defined. Also no craterlets visible anywhere on the
floor of Plato until the central craterlet was just glimpsed
later at 23:00-23:45, though seeing now III-IV (cirrus at times
in the sky). At this later time the NE rim was less blurred than
before. ALPO/BAA weight=1.
Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore
(Sussex, UK) saw the wall as normal. However Cameron points out that
Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely
(Covington, UK) at 22:10 UT noticed a brightening on the East wall and
at 01:10-01:25 UT suspected that the interior had a weak yellow-green
cast to it. Cook (Frimley, UK) states that orange colour was within the
interior crater, but green beyond the east rim at the 9 O'Clock and
the south east corner to floor blue/mauvre beyond the northern rim
NW/WSW. Foley sstates that orange and blue/mauvre might be spurious
colour, but green one cannot get this way. Cameon suggests chromatic
aberatons as a possibility but thinks that the observers concerned were
experienced enough to recognize this if it were the cause. Cameron 2006
catalog extension ID=239 and weight=0. Moore used a 15?" refletor and
Foley used a 12" refletor. Mosely experienced II seeing and good

On 2016 Jul 17 UT 03:49 P.Zeller (ALPO, Indianapolis, IN, USA)
imaged a pseudo-peak with shadow on the floor of Herodotus,
however the image scale and quality of this colour image were
not great and the observer suspects that it might be an
imaging artefact. ALPO/BAA weight=1.
P. Foley of Kent, UK, using a 12" reflector, seeing=III-II, noticed
that initially that the crater was pretty dull and that the floor
was a slate blue-gray in colour at 22:45UT. A noticeable green spot
inside the crater on the south east appeared at 22:25UT and vanished
at 00:50UT. Cameron notes that one doesn't get green with spurious
colour. Crater Extinction brightness measurements were made at 22:00 UT
(reading=2.8) and at 23:45UT (reading=3.7). The crater dropped in
brightness from 3.7 to 2.8 at 23:50UT and remained lower until 3.0 at
23:50-03:15 UT. A graph was produced and showed Proclus and Censorinus
at similar brightnesses, but Aristarchus variable. The Earthshine was

A bit more of a detailed report is as follows: "Upon the 13th of May,
1870, there was an "extraordinary display," according to Birt: 27
lights were seen by Pratt, and 28 by Elger, but only 4 by Gledhill, in
Brighton. Atmospheric conditions may have made this difference, or the
lights may have run up and down a scale from 4 to 28. As to
independence of sunlight, Pratt says (Rept. B.A., 1871-88), at to this
display, that only the fixed, charted points so shone, and that other
parts of the crater were not illuminated, as they would have been to an
incidence common throughout.(30) In Pratt's opinion, and, I think, in
the opinion of the other observers, these lights were volcanic."

G.Amery (Reading, UK, seeing=II) saw a brilliant white rim,
bands and central peak. There was also a clearly seen white
glare like feature over the ESE wall that had a direction
opposite to the crater interior bands. Cameron states that
Foley says that this is usual. High CED brightness readings
obtained. M.Cook of Frimley, UK, took CED measurements at
23:35UT and recorded a brightness of > 4.9. Reported a
reversal of spurious colour - Cameron suspects that this was a
local effect. No spurious colour noticed by anyone else.
However the brightness of the crater was confirmed by other
observers. Mosely suspected a brightness change on the inner
east wall at a relative position of 8 O'Clock. Cameron 2006

F. Graham took some photos of the Cobras Head and found a blue cloud
about 50 km in diameter and scattering light - Cameron says that
this indicates high density. Darling found the Cobra's Head obscure and
variable "clear and bright to diffused". Cameron was alerted observed
(02:40UT) variations with periods of approximately 30 seconds, and
thought that she could see a red tinge on the east rim of Aristarchus -
checks elsewhere found no other colours. Darling found that a blue
filter enhanced the effect and a red filter made it disappear. There
was a blink at 02:55UT but no blink in the Cobra's Head, which looked
fuzzy and lacking in detail. The effect was confirmed by Weier, who
also saw two dark spots in the Cobra Head in blue but not in red light.
The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall
7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south
wall 7.0, East wall 8.0, and the central peak 10.0. Observer details

On 1955 Oct 02 at UT 05:30-05:55 Bartlett (Baltimore, MD, USA, 3.5"

crater: "Viol. gl. on E, NE rim, over EWBS resembled a viol. mist.
Crater itself was hazy, could not get a sharp focus". The Cameron 1978
catalog ID=615 and weight=4. The ALPO/BAA weight=2.
Mobberley noticed that Torricelli B was bright and had an even brighter
spot on the inner north wall. The observation was made from UT19:45-
21:40 using visual and video techniques. There was also a bright region
NNE of Toricelli B, that was noticed. Foley examined the video and
found that the crater faded in brightness over time and also the bright
area to the NNE was not as bright on video as had been seen visually.
Foley speculates that because the CCD camera was sesnitive to the near
IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and
also saw the bright spot on the inner north wall - but saw a blue halo
around the crater. Response in blue filter, darkening over whole
region. Brightness measures with a crater extinction device (CED)
indicated that the crater was 80-85% the brightness of Censorinus.
There was a bright area NNE of the region. M. Cook observed 22:10-
22:16UT (15cm reflector and seeing III-IV) and also saw that the crater
was very bright indeed with a spot NNE of the region (same position as
28/28 1985 observation) - suspected that the crater might have been
brighter than Censorinus, but judgement effected by seeing. In a blue
filter the crater dulled leaving the bright spot prominent (but only
during a good moment of seeing) - therefore had some suspicion of
seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the
area, but the seeing was even worse - but did manage a check of the
brightness of Torricelli B to Censorinus and now made it one quarter of
that of Censorinus and no sign of the crater dimming in the blue as had
been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at
21:15UT (Dec 27) thought that Torricelli B looked normal and saw no
colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images
through red+IR (Wratten 25) and IR (Wratten 87) but found no colour
differences, though there was a very slight hint that a brightness fade
may have occurred between those two observing times. Note that this
report does not have an entry in the Cameron 2006 Extension Catalog.

On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300)
noticed a lack of detail in the Cape Agarum area - he would normally
have expected to have seen some craterlets. However he would not rate
this observation much because the seeing was only III and he does not
think that it was an obscuration. However just in case he wanted to
record this report in the archives. ALPO/BAA weight=1.
Alphazen Alpha 1972 Oct 23 UT 22:10?-22:13? (Stoke-on-Trent, UK,
21cm Newtonian, x217, seeing very good). Flickering colours seen
on the north field of Alhazen Alpha mountain. Above UTs
estimated by the observer, but the duration of the effect was 3
minutes. Colouration centred on the hills that run north to
south between Mare Anguis and Mare Crisium. The colour
alternated from east to west about 2 or 3 times per second. The
colour was not apparent to the north or south, or indeed on any
other features. Telescope field of view moved, but effect stayed
in the same place on the Moon. Moon't terminator scanned for 15
minutes afterwards, but the effect did not recur. The colour
seen was mostly red, with a band of orange, and a strip of
yellow nearest the hills, the proportions being 6:2:1. The bands
seemed to arc up steep above the Moon's surface and flatten out
over the mare surface either side of the hill features. No
filters were used in the observation. Observer suspects some
kind of diffraction spectrum to explain the larger dispersion in
the red end of the spectrum. ALPO/BAA weight=3.

Cleomedes Alpha 1993 Sep 03 UT2200-22:20 G. North (UK, 18.25"
reflector, x86 & x144) observed it to be a strikingly brilliant
'splodge' seen in the mostly shadow filled interior of
Cleomedes, and around this splodge was a faint halo extending
symetrically in an eastwards direction. The splodge was the
mountain Cleomedes Alpha. Strangely no shadow from the mountain
was seen to be cast onto the halo on the east. Observer alerted
other observers by phone, and upon returning to the scope found
that the splodge had faded in brightness and continued to fade
over the next hour as one would expect from a mountain at
sunset. Some heavy spurious colour was present. J. Cook & M.
Cook (Frimley, UK) observed at 22:20-22:25 and found the bright
splodge, but no halo. M. Cook re-observed later and confirmed
normal fading of splodge. Roscoe observed from 00:30UT next day,
but by that time Cleomedes Alpha had set and was no longer
visible in the shadow filled floor. S. Beaumont had observed
earlier at 20:00 but had recorded all as normal in Cleomedes.

On 1979 Jul 14 at UT 00:24-01:10 P. Madej (Huddersfield, UK, 15cm
reflector, x35, x52, x73 and x110, seeing IV-V, transparency very
good). Note that the observing date was also written as Jul 18th in the
original report? Puiseaux was very clear in white light, but could not
see the cenrtral peak. The central peak though was visible through a
Waretten 15 (yellow) filter. The ALPO/BAA weight=1.
Messier A 1951 Oct 20 UT 00:00? Observed by Moore (England)
"Brilliant white circular patch in it. has seen it & Messier
blurred several times." NASA catalog weight=4 (good). NASA
catalog ID #545 Note that the date and time given are probably
wrong as the Sun is ~7deg below the local horizon at this time.
ALPO/BAA weight=1 to reflect this error.
On 1904 Aug 01 at 05:00? Pickering (Echo Mt., CA, USA) UT Plato:
"Bright hazy obj., 2" diam. on floor, Obs before & after were normal".
The Cameron 1978 catalog ID=318 and the weight=4. The ALPO/BAA
weight=3.
Jansen 2013 Aug 26 UT 00:30-01:30 P. Grego (Cornwall, UK, 20cm
SCT, x200, seeing II, transparency good) observed a dark patch
just east of Jansen D. He had not seen this before. There maybe
a depression here hinted at in LOLA ndata. ALPO/BAA weight=1.
On 2008 Oct 19 during 05:40-06:30UT D. Holt of Chipping, UK observed an
anomalous patch of illumination just to the west of the centre of the
Posidonius J crater. It is possible that this is just some high ground
on the floor protruding through the shadow filled crater at sunset.
Therefore this has been assigned a weight of 1 for now, just in case it
is a TLP - until proven otherwise.
Aristarchus 1976 Aug 15 UT 23:00-23:45 Observed by Garbott (2)
(Bedfordshire, England, 10" reflector x500, seeing Antoniadi I)
and by Moore (Sussex, England, 15" reflector, x360, seeing
Antoniadi IV) "Noted blue color on N. wall extending toward
Herod. Also saw orange color in S. region. Confirmed by father.
(similar to many of Bartlett's rept's.), More noted nothing
unusual at 2320h." NASA catalog weight=4. NASA catalog ID #1444.
ALPO/BAA weight=2.
On 2009 Oct 09 UT11:00-11:04 NASA's LCROSS upper centaur stage,
followed 4 min later by the observation spacecraft, is due to impact
into a the crater Cabeus in the hope of kicking up some dust and
possible frozen volatiles. Note that this description is intended for
observers on the date of impact and it is doubtful that any new
science could be achieved by re-observing the same area months
after the impact. If you are observing on the date of impact, then
please observe around 11:00-11:04UT and ignore the predicted times in
the headings. However this report is included as techniqcally
if something is seen it is a TLP, albeit man-made! For those observing
on the date in question here are a few observing tips to maximize
the science of your observations: (1) If you are imaging, then please
try to obtain images before the impact because you can then subtract
these from images taken during the impact and hence show up faint
changes that you might normally miss. (2) If you have a spare scope and
camera,use this to observe through filters such as UBVR or I, or if you
have narrow band interference filters, try observing in
say Hydrogen Alpha, Methane, OH, or indeed any volatile that you
might expect to see in a comet (the main source of water at the poles).
(3) Please try checking the area long after the impact, just in
case other effects might trigger a TLP. (4) Please go to some trouble
to ensure accurate timings- these will be essential in order to
understand the sequence of events - assuming any are seen. Timings can
be obtained using a short wave radio or via a GPS. Note that you should
always use UT or UTC. (5) Please send any observations that you make
into the upload section of the LCROSS campaign observers web site. If
you belong to an astronomical society e.g. BAA or ALPO, then do please
send copies of your observations to the Lunar Sections of your society
or club. (6) Finally this desription will be updated a day or two after
the planned impact.
On 2009 Sep 09 UT23:31:43 P.Grego (St Dennis, Cornwall, UK, seeing II-
III) suspected a flash south of Cabeus, just beyond the terminator.
It was not bright, and lasted a fraction of a second. Thinks it might
have been illusory as he saw some fainter flashes (cosmic rays?)
during that nights observing session. ALPO/BAA weight=1.
On 1973 Oct 17 at Ut 11:30 Androsan (Edmonton, Canada, 6" reflector,
x230) observed a glow 1-2 sec reappearance of Saturn's rings at a place
of ring's appearance on the dark limb. The observers attributed it to
Saturn and its rings. Cameron speculates that it might be due to gas or
dust at the lunar surface. Eye was attacted to the glow which
delineated the limb at a position angle of 210 deg at emersion, at
Earthshine at Edmonton. The Cameron 1978 catalog ID= and weight=2. The
ALPO/BAA weight=1.
S. Beaumont of Windemere, England noted that the crater appeared
to be divided into two. Cameron 2006 Extension catalog ID=381
and weight=3. ALPO/BAA weight=1.
Aristarchus 2004 Dec 03 UT 00:00-01:00 Observed by Brook (Plymouth,
England, 60mm OG x120) "Fluctuation in the brightness in Aristarchus
still present but less pronounced than yesterday. Also saw the bright
short ray on the opposite side to the main ray in Aristarchus that
Amato saw yesterday - but this may be normal?" BAA Lunar Section
report.
