Barker's Quadrangle (26W, 34S) 1949 Mar 03 UT 20:00 Observed by
Moore (England, 12" reflector) "Whole area hazy. (in Capuanus?
see Wilkins and Moore, The Moon, p124) (It may not be this
identification as 3 of 4 obs. are in dark, some nr. FQ so

On 1965 Dec 27 at UT Bornhurst (Monterey Park, CA, USA, 10" reflector)
and (Harris (Whittier? CA, USA, 19" reflector?) observed brightening of
Aristarchus in Ashen light. Cameron says that this is an independent
confirmation? The Cameron 1978 catalog ID=918 and weight=4. The
ALPO/BAA weight=2.
On 1982 May 26 at UT 20:25-20:40 Kalauch (Berlin?, Germany, 9"
refractor, x60, T=1(best) and scintilation=2) found Aristarhus to be
"very visible" in Earthshine - which was very clear. At 20:25 UT
Aristarchus was seen to blink irregularly and then it attained
magnitude 7 (red). Telescopes and eyepieces were changed but did not
effect the appearance. It disappered at 20:40UT. Cameron 2006 catalog
ID=168 and weight=2. ALPO/BAA weight=2.
On 1983 Feb 15 at UT 18:00? G. Amery (Reading, UK) found that he could
not see Aristarchus in Earthshine, despite less normally priminent

On 1986 Mar 15 UT 19:51-19:55 A. Cook (Frimley, UK, Naked Eye
and 12" reflector, x60, seeing IV, transparancy poor)
observed a naked eye flash at 19:50.5 UT in the Mare Nubium
area. The flash was white in colour and lasted not longer
than 0.5 sec and was about magnitude 2 at most in brightness.
There was no rise or fade associated with this flash. Upon
checking the area with the telescope, the observer reproted
seeing a faint fuzzy small patch that came and went over
several seconds in the same general area - but this may have
been due to the seeing conditions and/or glare from the
bright side of the Moon. The patch area was about the same
size as Aristarchus, i.e. approx 40 km across. Note however
that observing conditons were too poor that night to see
Aristarchus. At later observing sessions from 20:30UT
onwards, the patch was not seen. The ALPO/BAA weight=3.
On 1990 Jan 01 at UT 16:55-18:45 H. Miles (Cornwall, UK) observed that
Aristarchus was seen in Earthshine at 16:55UT before the limb (was
visible in Earthshine?). "1705 Aris>>1723 fading 1727 > again." Then:
"1740 Aris << and just visible at 1845". Apparently Foley suspects that
Aristarchus had brightened up before 16:55UT (shwen H. Miles started to
observe) and then gradually retruned to normal. The Cameron 2006
catalog ID=385 and the weight=0. The ALPO/BAA weight=1.

On 1994 Jun 14 UT 21:45-22:00 G.Rogers (Crendon, UK, 3" Zeiss
refractor, sky conditions perfectly clear) reported seeing three
very large whitish clouds against the Moon. The strongest seemed
to "stem" from the vicinity of Santbech crater (crater
identified the next day from an atlas), and was a milk chocolate
colour near the stem. The other two large clouds were to the
north - in the general area of Mare Fecunditatis and Mare
Crisium though perhaps slightly further west and in contact with
the terminator? The effect was confirmed (independently) by 4
other observers using the same telescope. The telescope was
moved but the clouds remained in the same position over the
Moon. This report comes from The Astronomer Jan 2013 p 230.

On 1983 Apr 19 at 21:45UT M.C. Cook (Frimley, UK) reported that
Censorinus' exterior white patch was grayish at this time and there was
a "momentary glow outisde the crater to the North West. The Crater
Extinction Device brightness measurement for Censorinus was 4.0 whereas
Proclus was 4.4. Cook was expecting a lower CED brightness measurement.
Foley notes that Censorinus is usually brighter than Proclus. On 1983
Jan 29 Chapman obtained a very high brightness measurement for this
spot. The Cameron 2006 catalog extension ID=212 and the weight=3. The

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
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

bright points about 5 magnitudes brighter than any other part of the
Moon. The Alpine valley points directly between these two points. "Came
from apparently featureless area. Both points about the same size, but
different shapes ~ width of alpine valley" The observer used 4

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 1955 Aug 27 at UT 01:51 McCorkle (Memphis, Tennessee, USA, 6.5"
reflector, x200) observed a 2nd magnitude bright flare on the dark side
of the Moon. This remained steady, fading slightly before abruptly
disappearing. Cameron suggests that this might have been a meteor. The
Cameron 1978 catalog ID=604 and weight=0. The ALPO/BAA weight=1.
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

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
all seemed normal. Quick checks were made again on Tycho

Williams of the UK, on 1892 Aug 23 at Moon's age 10.0 days, noticed a
spot now rated at +1.5 (in brightness) that had been seen on the 21st
Aug, near Picard. Williams comments that this is the only obsewrvation
that departs "much" from the curve of diurnal brightness. The spot was
descibed as "nearly as large as Picard and nearly half as bright. This
observation was reported in the Astronomical Register of the Royal
Astronomical Society and is not included in the Cameron catalogs. It is

initially no craterlets in Plato, despite the Moon being at a high
altitude. At 01:45UT the northwest corner of Plato was red. Again no
other craterlets showed. He found the surrounding wall to be too bright
and this was confirmed by Crater Extenction Device readings and had
problems focussing on the crater. By 02:00-02:50UT he noticed
variability in the visibility of the craterlets. By 03:48UT the central
craterlet was much brighter than before and the crater doublet had
brightened but the southern craterlet was still invisible. Cameron
comments that Marshall was a very experienced observer. A. Cook (of
Frimley, UK) obtained a photodiode line scan image of Plato. The
brightness of the north west wall was brighter than the bright area on
the west wall. Marshall and Mosely both saw a dark area on the floor of
Plato close to the south wall (from clock position of 11 o'clock. There
was a prominent white spot on the floor and the central craterlet was
seen, but only under good conditions. Mosely does not discuss the west

Plato 1982 Jun 02 UT 22:00. Mobberley could not see the
central craterlet on the floor of Plato tonight. Foley notes
that he could only just see the central craterlet on nights of
2-5th Jun and it was of reduced in brightness from normal.
North reported that the floor seemed nearly black, but
brighter in a green filter (x144 magnification used). All
three observers compared the Plato area to other areas for

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

(Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5,
x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red
25. The illuminated west crater wall stood out brilliantly in blue
light, much more so than in white light. This was true also of
Aristarchus. Red light did not increase contrasts in Herodotus any more
than they were in white light. Shadows in Herodotus appeared as black
as the night west of the terminator and remained that way throughout
the observing period. No TLP seen in Herodotus tonight. A possible TLP
was seen to the west of Herodotus near the terminus of Schroters
Valley. It was noted at the beginning of the observing period that
there were four very bright spots of light, one near the end of
Schroters Valley, the other three grouped together a little farther
north. Although not far from the terminator they were definitely east
of it. It was noted that all of them nearly vanished in the Blue 38A
filter while Aristarchus and the rim of Herodotus gleamed brilliantly.
At 5:19UT it was noted that the most brilliant of the four lights, the
one near the terminus of Schroters Valley, had faded almost to
invisibility in white light. When first seen it had been brighter than
Aristarchus. It remained very dim after this through the remainder of
the observing period, and was unchanged at 7:35-7:49UT when I again
examined the area. The other three bright spots remained brilliant and
unchanged."

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.

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

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.

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

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."

detectabilty changed such that sometimes it was visible and sometimes
not. Foley (Kent, UK)noticed that the central craterlet could only just
be seen between June 2 to June 5 and was much less discernable than
during the previous lunation. No CED brightness measurements made. The
floor of Plato was noted to be very dark though. Cameron 2006 catalog

crater. This is probably normal, but we are flagging this up
as a weight 1 TLP, in order to obtain some repeat illumination
observations and confirm that the strength of the blueness is
normal.

Plato 1973 Aug 13 UT 22:25-22:35 observed by Pedler (Devon, UK).
Observer noticed a slight blink on a lighter patch on the floor
just beneath the south(?) rim using Moon blink filters.
ALPO/BAA weight=1.
David Darling observed bright glittering on Aristarchus. This
was followed by a flare up in brightness at 00:38:05 UT in the
comet-like ray area of the crater equivalent in intensity to the
central peak. Then he saw another one on the north east rim of
Aristarchus of the same brightness. A third flare was seen at
00:49UT in south of Herodotus, on the comet-like ray. Another
two flares were observed at 00:56UT on the north west rim of
Aristarchus. Darling suspects that these effects were due
to seeing effects and Cameron agrees. However Weier suspects
that they were TLP? Brightness measurements by Weier were for
the south west rim of Herodotus 8.0, for a spot at the Cobra's
Head 9.0 and 7.5 for C.H. Cameron apparently did not see the flashes
but did suspect that the interior of Aristarchus was a bit unusual.
Don Spain did not see anything unsual at all. Cameron 2006 extended

On 2002 Mar 29 at 02:20-02:38UT C. Brook (Plymouth, UK, 60mm refractor,
x120 - no cloud, slight haze, no wind, seeing good) noticed during
first part of observing period that Aristarchus was getting steadily
brighter, very much brighter than Proclus. This continued until 02:36UT
when it dimmed suddenly over a period of about a minute or so. No
colour effects seen. ALPO/BAA weight=2.
On 2002 mar 29 at 02:20-02:38UT C. Brook (Plymouth, UK, 60mm refractor,

when it dimmed suddenly over a period of about a minute or so. No
colour effects seen. ALPO/BAA weight=2. Just as an after thought - was
it Aristarchus that was varying, or Proclus?
Louderback, of South Bend, WA, USA observed a bright area over
Mons Anguis and Eimmart - it resembled a comet and had a bluish
colour and varied in brightness. The colour was confirmed as it
was not seen in a red filter but could be seen in blue and white
light. Other features were checked but did not show anything
similar although a violet glare was suspected in the blue filter. A
sketch was made. Observer made Eimmart 8 in brightness at 07:30UT.
Noted that the area around Eimmart appeared opaque at times and less so
at other times. At 08:52UT the phenomenon was seen again. On May 2nd
a bright spot was still seen in the region but it was not changing
dimensions. During the observation on Apr 30th the atmospheric
transparency was excellent. A 2.5" refractor was used. Reference:

On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor,
seeing=II) found that the inner bands of Aristarchus were hard to see,
this was odd because the seeing conditions were good and he usually
sees them? However he did not believe that there was any obscuration
going on. The Cameron 2006 catalog ID=37 and weight=0. The ALPO/BAA

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

23:50UT on Jul 1st 1977 and 00:10UT on Jul 2nd 1977 observed
Aristarchus. The south wall of the crater was reddish, extending
down to the outer south east wall (IAU). However seeing was no

spurious. His report was submitted only in case any other
observers reported something similar. ALPO/BAA weight=1.

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

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.
