On 1987 Nov 28 M. Cook (Frimley, UK) found Censorinus varied in
brightness as measured using CED devices. P. Foley decided that the
north was was much brighter than Proclus (beyond the limits of the
scale). However both Moore and Mason agreed that the north wall of
Proclus was very bright but shimmering around in the bad seeing. They
did not see any bright spots either. A.C. Cook (20:18-20:44UT)
confirmed that the north wall of Proclus was very bright. Towards the
end of the observing period the north wall had faded from this maximum
brightness - Cameron suspects that this might have been as a result of
an eyepiece misting up. The TLP was also observed by Foley (Maidstone,
Kent, UK) and he reported: "Bright spot on north wall, Moon blink
reaction". A BAA Lunar Section report with extracts from the 2006
Cameron catalog. Cameron 2006 catalog ID=315 and weight=4 (or 5?).

On 1987 Nov 28 UT at 20:14 (possibly earlier)-20:44 M.Mobberley saw the
northern rim of Proclus very bright for first quarter. There were
streaks half way up the wall and these seemed to vary in brightness and
length in seconds. Seeing was at first suspected but became doubtful
over this being a cause. There was also another bright streak that
changed brightness over 5 minute intervals (Cameron says that this is
not atmospheric) Apparently video was taken and confirms the effects. A
sketch was also made. M. Cook detected a blink with coloured filters
i.e. being brighter in red light (Also apparently confirmed by
Louderback). Estimated the north west wall was x3 brighter than
Censorinus. Censorinus itself varied in brightness as measured using
CED devices. P. Foley decided that the north was was much brighter than
Proclus (beyond the limits of the scale. However both Moore and Mason
agreed that the north wall of Proclus was very bright but shimmering

On 1979 May 04 at 21:30-22:00UT Coates detected a star-like point
inside Hipparchus L crater using averted vision. Cameron in her 2006
catalog extension comments that Hipparchus L is a highlands impact
crater with a rille on the western ejecta blanket. The crater is the
smallest one in a chain that are sequenced to be half the size of the
previous crater in the chain. Apparently the largest crater in the
chain is Hind with a largely landslide covered floor - although on the
south is a dome? with a summit crater. Cameron's 2006 catalog extension
gives this TLP an ID of 51 and a weight=2. The ALPO/BAA weight=2.

On 2009 Aug 28 at UTC 17:00:15-17:00:42 S. Khachatryan (Yerevan,
Armenia, 127mm Maksutov-Cassegrain, x171, seeing 9 (1=worst and 10-
best), Transparency 5-6 on a scale of 1 to 6) observed in the Chacornac
area a series of fiery sparks (dot like with tiny rays), slightly
elongated with the multitudinal rays orientated towards the south west
direction. The colour was mostly red, with some yellow. The final flash
was the most clear. The TLP was tiny in area, but "was distinctly
bright against any other object on the Moon". The positional
uncertainty of the location of the spark effect was approximately +/-
150 km, based upon an examination of an atlas afterwards. Just prior to
the spark effect, something dark, small and fuzzy (only just discrnable
to the eye, through the eyepiece) was seen to pass from the west across
the Moon in a slight curve, round the surface of the Moon to the east
(post observation estimate: seen for 3.5 sec and covered roughly 8% of
the lunar diameter in that time). The area of the dark object was
comparable in size to (or slightly less than?) craters such as
Autolycus F (diameter 3km) or le Monnier E (diameter 4km) i.e. on the
limits of vision of the scope used. The location of the flash was not
exactly at the same location as the dark object passed across, but gave
the impression of starting from it? A back of the envelope calculation
of the lunar diameter covered in the time quoted gives an approximate
speed (at the lunar distance) of 80km/s or on the very high end of
typical meteor streams that pass by. At closer distances, and
recalculated velocities, it is unlikely to be a satellite in low Earth
orbit (20m/sec at 100km distance), but could perhaps be a bird or
insect at a few km range? So was this dark object something in our
atmosphere by chance passing across the field of view close to the time
of the TLP flare or was at the lunar distance and related to the TLP?
Incidentally, no attempt was made during this observation to move the
scope to check that the TLP remained stationary against the Moon. The
ALPO/BAA weight=2.

Although the crater was on the night side, a small bright spot
was seen. This was blue, almost UV, and equivalent to a star of
magnitude 2. It flashed over intervals of about 30 seconds
and changed in colour from UV to blue. The BAA Lunar Section
TLP network was alerted. Mobberly and J.Cook did not see much
although J. Cook may have seen something, but located else where?
Cameron lists this as a confirmed? observation? The Cameron

effect from the original TLP report, but did see, immediately at
looking at Tycho a very faint hint of redness in a pencil thin
arc (< 1/4 circumference of the rim) confined to the top of the
rim of the well-lit north east wall. Coloured arc similar in
thickness to Rupes Recta, but not as sharply defined. The outer
(E) edge was perhaps sharper than the inner edge. The redness
was more on the inside of the top of the rim. The outside of the
rim was bright white. This effect was seen in three different
eyepieces, at 311x, 224x and 400x. Checked for the effect on
other craters nearby but could not see this effect anywhere
else. The colour had dissapeared by 01:02UT. The fade took about
1-2 minutes. Observation of Tycho continued until 01:06UT, but

Aristarchus 1976 Jun 06 UT 21:30-21:40 S.Spencer and R. Hunt
(60mm refractor, x150 and x60) both observed red on the SW
corner of Aristarchus. ALPO/BAA weight=1.
Atlas 1966 Dec 21 UT 17:10 Observed by Andre (Belgium, 3" refractor)
"Bright spot on SE part of floor, not seen in photo on 12/18/66" NASA
catalog weight=2 (low). NASA catalog ID #1003.
2012 Sep 24 UT 22:00-23:00 Copernicus. E. Horner (Salisbury,
UK, 15cm reflector) observed a prominent red arc where the
sunlit part of the interior wall met the shadow. Sometimes the
arc was 1/4 the way around the interior, and sometimes half of
the way around. Telescope moved, but the red arc stayed where
it was. Eyepieces change, but the effect remained. Other parts
of the Moon checked, but no red seen. There were however
splashes of green e.g. Longomontanus on the terminator,
elsewhere further inland from the termionator, and little
splashes of green on Mare Frigoras - but lasting a brief time.
The red colour was as strong as a red LED and the green similar
to that of the northern lights. The observer's husband was asked
to independetly check Copernicus and remarked that he could see
a little bit of green at the top and some red near the bottom,
along the line of the internal shadow. Although there were
checks for red elsewhere on the Moon and none were seen, the
Moon was starting to get low and it is typical of spurious
colour in a few respects. Therefore the ALPO/BAA weight=1 for
safety.
On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3"
refractor, x90, seeing conditions: "at,. boiling") noted a coloured
area on the west wall of Copernicus that was unusual in appearance -
however other craters along the terminator had a similar effect. There
was also a "dazzling bright spot on the E. rim and he witnessed 6
flashes from the lighted part of Copernicus over a very short time
interval. Cameron comments that the colour may well have been dur to
chromatic aberation because a refractor was used. The Cameron 2006
catalog ID=408 and the weight=0. The ALPO/BAA weight=1.
On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3"
reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc.
bright interior uniform gray". The Cameron 2006 catalog report is
slight unclear as the description for thnis 1990 Aug 30 TLP also
includes Copernicus and Censorinus in the list of TLP craters. So one
description which might refere to Copernicus, could possibly have been
meant for Proclus, namely: "Dazling bright spot on E rim. Rotated
eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog
ID=408 and weight=0. The ALPO/BAA weight=1.
On 1980 May 25 at UT 22:18 G. Blair (Bridge of Weir, Scotland, 216mm
reflector, seeing II-IV) suspected a short sharp flash, white in colour
north of Tycho's north wall. Nothing more seen. ALPO/BAA weight=1.
M.C. Cook (Frimley, UK) got an abnormally low brightness reading for
Proclus, despite nearby Censorinus being normal. Crater Extinction
Device used. The Cameron 2006 Extension catalog ID was 163 and the
weight was 3. The ALPO/BAA weight was 2 too.

On 1988 Dec 18 at UT20:25 W. Cameron (Sedona, AZ, USA - TV camera
telephoto) noticed on a live TV shot of the Moon (apparently channel 3
TV broadcast at 11:25PM local time), that Proclus was brighter than
Censorinus (or Dionysus) and was the brightest feature on the Moon. It
was photographed from San Juan in Puerto Rico. Cameron 2006 catalog ID=

On 1982 Apr 04 at UT 23:30-00:25 P. Madej (Huddersfield, UK, 7cm
refractor & 16cm reflector) noticed the TLP in his refractor
first of all at x25. So stepped up the magnification to x111 and
found the crater brightness not what he was expecting. He tried
different filters but found no difference in brightness. With
the 16cm reflector however some changes in brightness were
dected. The crater has a very pale yellow colour and it was
slightly darker than Lacus Somniorum. P. Foley tried to confirm
at 00:09 but the crater looked normal then. The Cameron 2006
catalog extension TLP ID is 167 and weight=3. ALPO/BAA weight=2.
On 1990 Jan 07 at UT 20:20-20:58 G.North (Herstmonceux, UK) thought
that he detected dullness in Torricelli B crater - Cameron comments
that this cannot be shadow). The Cameron 2006 catalog ID=386 and the

On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5"
reflector, x159) observed an "anomalous black bar across Aris. Nearly
digonal to terminator." The nearby crater Prinz had curious shadow
patterns, perhaps related to the rising sun projecting shadows from the
eastern rim and "reflected down"? "At 0224 W wall had a break in it & a
diffuse glow where it should not be. Manske thinks it was Earthshine
effect. At 0305 Weier saw Manske's bar - with diffused light and
flicker like an aurora - like a gas with electric charge. At 0325 saw a
strange glow in Aris. but may be due to atm. though thought it to be a

On 1993 Sep 28 at UT 04:30-06:10 S.Beaumont (Cambridge, UK)observed
that the north east edge of Herodotus appeared as a "highland area
spilling over into" the Cobra's Head border or "overlook". The shadow
on the elevation was contiguous with a similar shadow over the Cobra's
Head "like a darkening of the terrain. Shadow appears softer diffused

On 1821 Jan 16 at UT 21:00 S. Cooke (Stonehouse, UK) An
effusion of smoke effect, which lasted about a minute, seen.
It appeared like the fluttering of a bird and passed over the
Moon before it evaporated, and must have been foreshortened,
as it seemed in effect to have passed over the whole disc,
starting from west of Menelaus, and near Plinius. ALPO/BAA
weight=1.
Peter Foley (Kent, UK, 8" reflector, seeing=II) noticed that
the floor beneath the north wall, and the area over the north
wall were indistinct (almost out of focus). Despite looking
elsewhere in the crater and surrounds, no other blurring
(obscuration of detail) could be seen, indeed everywhere else
was sharp and detailed. Foley tried several eyepieces but this
made no difference. He used a crater extinction device but
found no variations in brightness. There was a slight
darkening when he used a red filter in the Moon Blink device.
The obscuration effect weakened between UT20:56 and 21:10,
was difficult to see at 21:13 and had finished by 00:15.
Patrick Moore (12" reflector, Dublin, Ireland) saw nothing
unusual when he started observing at UT 22:00. Cameron says
"Photos marked at location of phenomenon". Cameron 2006
extension catalog ID=37 and weight=5. ALPO/BAA weight=3.
On 1980 Apr 28, Louderback (South Bend, WA, USA using a 8" reflector
and a 2.5" refractor) observed a very bright reg region on top of the
south west rim of Aristarchus crater. This was on the same side as the
ray system between Aristarchus and Herodotus. Louderback noticed some
chromatic aberation - blue where he had seen the red patch before.
Louderback suspects chromatic aberation was the cause although did not
see red in that region ever again. "Patch was between his observation
points A and C. Point C was 5 points brighter in the red filter than in
the blue." A sketch was made. Cameron suspects that the TLP was real.
Cameron 2006 TLP catalog extension ID=92 and weight=3. ALPO/BAA
weight=2.
Louderback observed that the south west wall was a creamy deep yellow.
There was also strong fluorescent blue on the west wall of the Cobra
Head - Schroter's Valley area and this was similar to the violet glare
seen on Aristarchus at times. Violet was seen between Aristarchus and
the Cobra Head. Seeing coditions were poor. Brightening of a point
near C occurred roughly every 10-15 seconds and lasted 0.5 sec -
(Cameron concludes that this was not due to the Earth's atmosphere).
A 0.2 step drop in brightness was seen on point A (twin spots).
Point C had reduced by 0.6 steps. Elsewhere was stable in brightness.
Cameron 2006 catalog ID=281 and weight=4. ALPO/BAA weight=3.
Variations in vapor column rising from the Cobra Head feature

the southern station of Harvard University in Arequipa, Peru.
Aristarchus normal in red and blue filters however the
Cobra Head part of Schroter's Valley was brighter in blue.
Indeed it was very dull in red - Louderback says that this
was not surprising as the whole areas around Aristarchus is
brighter in blue. Louderback is an experienced observer
of the Aristarchus area of more than 10 years. Cameron 2006

On 2009 Jan 09 at UT 20:00 P. Brierley (UK) took a CCD image of the
Aristarchus area - P.Grego upon examining this comments that he thinks
that Schiaparelli crater looked "muted in brightness -- it is normally

On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a
6" reflector, Seing = 6/10) noticed blue on the north east corner of
Aristarchus and an orange glow on the south east wall. They detected no
movement or change in brightness. The observer used both eyes, to make
sure it was not an eye defect, and three filters: red Wratten 25, blue
Wratten 82 and Violet Wratten 47. Porter found that the colours faded
for a duration of 5 minutes and then returned. Their right eye gave a
good view and using their left eye they suspected that it was 0.5 steps
brighter than the remainder of the crater. The suspected colour
remained visible, even under moments of good seeing conditions. The
colour eventually faded over time and was eventually gone. Porter
reportd seein gcolour here on the following night. Apparently other
bright spots showed no colour. Fitton suggests that the filters used
confirm that the south east wass was definitely red in colour. The

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.

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.
