display of lights. Says not effect of sunlight" NASA catalog weight=4
(high). NASA catalog ID #167.
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.
Censorinus 1981 Apr 15 UT 22:15-23:10 M. Cook (Frimley, UK),
using a 12" reflector,found Censorinus to be glowing exceedingly
bright and was brighter than Proclus. It dulled later, but was
still brighter than Proclus. Censorinus was also slightly
brighter in blue than in red light. Cameron 2006 catalog

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

lights. 27 seen by Pratt, 28 by Elger, only 4 by Gledhill. (independ.
confirm. ?" NASA catalog weight=5 (very good) NASA catalog ID #168.
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."
ALPO/BAA weight=4.
Mobberley of Suffolk, UK, and using a 14" reflector and
seeing=I-II saw yellowish/brown streaks within Aristarchus. A
sketch indicates that these extended from a region on the east
floor to the north west corner, and then finally onto the
bands on the west wall. Cameron 2006 extension catalog ID=132

Madler 1962 Apr 22 UTC 08:24 Observed by Wildey, Pohn (1st measurement)
(Mt Wilson, CA, USA, 60" reflector with photometer) "Photometric
measures show change in brightness from Vmag=3.79 to V=4.40. The
average brightness for age 17d is V=3.99. Crater faded from .2 mag

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.

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)

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.
Aristarchus 1974 Sep 08 UT 04:45-06:30 Observed by Cowan and Johnson
(Dublin, TX, 8" reflector, x59, x152, S=7) "Saw a bright luminous,
blue, misty cloud on th NE rim. Obscur. for 1st hr. then gave way to
pink & features became vis. Cloud was tear-drop shape. No movement to
glow. Pink cloud glowed too. Very tenuous by 0130h. (Nakamura says
there were no seismic events within several hrs. of this time). Another
person saw it without being advised as the where it was." NASA catalog
weight=5. NASA catalog ID #1393. ALPO/BAA weight=4.
On 2009 Sep 11 UT00:15-00:20 and 01:00-01:05 C.Brook (Plymouth, UK, 5"
O.G., x100, seeing tremourlous but definition improving over time)
noticed that the central peak(s) in Alphonsus were brightening
gradually. No effect was seen earlier at UT23:30-23:35. One presumes
that the effect also occured between these two observing times?
The observer suspects that this was not a TLP, but is uncertain.

Tycho 2006 Jan 22 UT 06:34-06:36 Observed by Fabio Carvalho
(Assis, Sao Paulo Brazil, 25cm f/6 Newtonian) "Green colouration

On 2009 Sep 11/12 UT23:28-00:00 M.C. Cook (Mundesley, UK, 90mm Questar,
x80 and x190, seeing II and transparency moderate-poor) observed
pink on the north west rim of Tycho and green-blue on the inner
SW rim. No sign of colour elsewhere on the Moon except for the
S-E rim of Plato that was red. The Moon was about 20 deg in altitude
at the time. The effect had gone by the end of the observing period.
A simulation of spurious colour in different directions
was generated by the BAA Lunar Section and found to possibly account
for these colours, although there should have been some strong colours
seen elsewhere in Tycho and none were. The BAA/ALPO weight=2.
Mare Numbium 1878 Oct 21 UT 01:02-03:00? Observed by Hirst (England)

Aristarchus and a pale shade of blue on the E(IAU?) half. The
effect faded from 19:56UT onwards and had gone 2 minutes later.
No information on whether other craters exhibited this effect,
given. Burgess, who observed later did not see any colour.
ALPO/BAA weight=1.
On 1980 Apr 18 at UT 19:00-22:30 P. Madej (Huddersfield, UK) saw two
very bright flashes on the eastern edge of Littrow, spaced 40 seconds
apart. Ricketts observed blue flashes approximately 20-30 sec apart and
Foley saw faint blue. Cameron 2006 catalog ID=86 and weight=5. ALPO/BAA
weight=3.
On 1980 Apr 16 at UT 20:00-22:20 P.W. Foley (Kent,UK, 12" reflector,
seeing II-III) found that Aristarchus could barely be seen. Therefore
it was not possible to take CED brightness measurements. Strangely
Cassini, Kepler, Plato and Mons Pico could be seen. However at
20:16 UT St Elmo fire-like flashes were seen coming from the interior
south east corner of Aristarchus at 20:16 UT and then the brightnesss
spread to fill the rest of he crater. Duration was about 5-20 sec
(Cameron comments: atmospheric effects?). The crater reached peak
brightness at 20:17UT (CED reading of 8). Foley comments that the
crater rim and area 16-24km around this (including Herodoyus) had a
translucent radiance. However at 20:25UT the brightness reduced
(including Herodotus) down to CED 3, however the blue radiance
remained. At 21:07UT Foley saw a star-like flash in the south east of
the floor (CED 3-4). Grimaldi was found to be of constant brightness by
comparison using the CED Brightness=2). At 20:20UT Amery (Reading, UK)
found Aristarchus to be a well visible circular fluorescent patch. At
20:40 Amery found the region between Aristarchus and Herodoutus was
glowing - appeared almost as a flare from Aristarchus and by 20:55UT
there was also a flare to the west of Aristarchus. At 20:27 Madej
(Huddersfield) detected only a slight glow from Aristarchus and the
region affected was small - indeed the glow had gone by 20:46. At 20:40
Ricketts detected a "continuous blue emission" - this had a cycle of 5-
10 sec (Cameron comments: atmosphere?). Saxton (Leeds, UK) detected at
20:42 "translucent effects and variations" at 20:42 noticed a star-like
point. At 19:00-21:40 M. Price (Camberley, UK) decided that Aristarchus
was fainter in brightness than normal. Peters observed a faint nebulous
spot at at 20:25-21:00 that changed in brightness in an irregular way.

1837Mar11 UT 15:27 (20:48 local time) T.G. Taylor (Madras,
India) whilst observing a star being occulted, noticed a
6th magnitude nebulous spot where Aristarchus should be. Had
never seen anything quite as bright as this on previous
occasions (except the day before). ALPO/BAA weight=2.
On 1881 Sep 27 at UT 19:00 Marokwic (South Africa) observed a comet-

Atlas 1968 Dec 24 at UT 09:15-10:45 Osawa (Kyoto-Ken, Japan, 8"
reflector, 9mm Ortho, Seeing=5, later worse) saw a slight
brownish hue on the northern shadowy bed in the crater. It was
difficult to see the difference between the glow and chromatic
aberation of the eyepiece. The tint never showed up in filters.
The ALPO/BAA weight=1.
On 1980 Apr 19 at UT 20:37-20:49) P. Madej (Huddersfield, UK,
77mm refractor, x83 and x111) at 20:37 UT saw a slight glow at
x83, quite small in size. At 20:46UT no glow was seen at x83.
At 20:49 a slight glow seen again, but unclear and
illdefined - appeared larger in area at x111. Observatons
ceased at 21:56 dues to clid. ALPO/BAA weight=1.
On 1980 Apr 19 at UT20:30-22:59. The following is quoted from the
Cameron 2006 catalog.... "(Buczynski) alerted by colleague (Greenwood)
who used filters W15 (IR), W25 (red), W44A (blue), & W58 (UV) and had
located a possible blink in it. (Bucz) used W15, W44A & W25. C.P was
very bright in W25 (red), dull but vis. In W44A (blue) & floor was
noticibly darker in W44A than in W25. Bright cp vis. In W15 & floor was
of a light shade. Other craters checked for color, none found. In 44A
floor lost some definition (gas?). Sketches from Bucz. & Greenwood.
(Pedler) at 2140, floor area around cp was seen in white & red as
normal but blink was vis in white, darker in blue. Checks of other
features were negative. (Amery) small dark center & small dark area -
not shadow - under S wall. N wall obscured by dark area extending N
onto surrounding mare. (normal?) which was difficult to focus (gas?).
At 2155 N wall now sharper & dark area less intense. Craterlet Cameron
in N wall clearly seen which was invisible 1/2 h earlier. (Saxton)
whole crater flashed and blinked at 2155. Could see detail in brighter
W 1/2 of crater - not seen earlier. At 2205 seeing poor, at 2215 it was
normal. (Blair) at 2155 used red & blue filters & in blue it was darker
than in red. W. wall not well defined. (J. Cook) saw spurious color on
N & S rims. Saw a pink tinge on SE rim. (A. Cook) saw spur. Color on
most craters as seeing deteriorated. Got a blink on SE region > red
than blue". The Cameron 2006 catalog ID=87 and the weight=5. The
ALPO/BAA weight=3.
In 1879 Oct 20 UT 23:00 (Local time Oct 21 9AM) Hirst (Blue Mountains,
NSW, Australia) saw a large part of the Moon covered with a dark shadow
that was as dark as the Earth's shadow would have been if there had
been an eclipse. Cameron says that this is a confirmed observation.
Note that the Moon was just before first quarter. The Cameron 1978
catalog ID=215 and the weight=4. The ALPO/BAA weight=3.
On 1969 Nov 15 at UT 02:20-03:20 Lagunas (Santiago, Chile, 10"
reflector) observed some brightenings in Aristarchus during the Apollo
12 watch. The Cameron 1978 catalog ID=1209 and weight=0. The ALPO/BAA
weight=1.
On 1980 Apr 20 at UT 19:25-23:43 P.W. Foley (Kent, UK, 10" reflector,
seeing II-III) found that Aristarchus was very bright in Earthshine
(also found on the photographs that he took), giving off a blue
"incadescence", the CED brightness reading was 5. Occasionally Foley
could see a star-like point in the south east corner. For comparison in
brightness he used highland terrain near to Grimaldi (CED=2). By
comparison, Buczynski and Lord, could not see Aristarchus. Earlier,
Geenwood saw the crater easily as a star-like point with a diffuse
exterior glow. Cameron says thyat this was confirmed by Buczynski and
Lord (?). At 20:35UT Amery decided that Aristarchus looked brighter
than normal. Pedler though described the crater as "small dim nebulous
blue or blue-green" that was invisible by 20:27UT. At 20:28-22:01 Blair
could not detect Aristarchus, nor could J-H Robinson at 20:40UT though
he did see it at 20:55UT as both diffuse and blue. Ricketts detected a
blow glow with irregularly spaced flashes of roughly 5-10 sec apart.
Cook's at Frimley, UK, saw no features in Earthshine. Cameron 2006
catalog ID=88 and weight=4. ALPO/BAA weight=2.
On 1980 Apr 20 at UT20:05-21:02 J.D. Cook (Frimley, UK, 12" reflector,
x60, seeing III-IV) at the start of this session found some bright
spots in the area of Copernicus, and at 21:02 detected some flashes in
this region. Cameron 2006 catalog ID=88 and weight=1. ALPO/BAA
weight=1.
On 1980 Apr 20 at UT 19:45-22:45 M.C.Cook (Frimley, UK) - colour
(probably spurious) seen on Piccolomini. Cameron 2006 catalog ID=88 and
weight=4. ALPO/BAA weight=1.
On 1980 Apr 20 at UT20:27 M.Price (Camberley, UK) saw a flash in the
Grimaldi-Aristarchus area. Cameron 2006 catalog TLP ID=88 and weight=4.
ALPO/BAA weight=2.
On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teignmouth, UK, 10.5"
reflector, x180) found, using a Moon Blink device, evidence of colour
on the flor patches of Fracastorius crater, brighter in blue than in
red. Also the floor to center varied in brightness in blue and in red.
Peters observed in white light and found the south east-south wall had
a slight orange cast and when a Moon blink was used it was less bright
in blue than in red light. M. Cook found spurious colour on the south
rim and also on Mons Pico. There was a colour blink reaction on the
southeast floor of Fracastorius - this was both faint and blurred and
not seen in white light. A.C Cook detected the permanent blink in the
south east floor of the crater at 21:47 and a fainter one in the north
west (marginally brighter in red than in blue). J.D. Cook found no
colour with the Moon blink device. 21:22-22:10 P.W. Foley got a strong
colour reaction with the Moon Blink device - brighter in red than in
blue and detected a pink colour visually on the south east wall 22:10-
22:45 (this did not give a blink effect though). Cameron 2006 catalog
ID=88 and weight=4. ALPO/BAA weight=2.
On 1988 Nov 15 UT 19:15 Holmes (Rockdale, UK, 215mm Newtonian) noticed
the Censorinus apron (just east of the crater and including the rim)
was fuzzy but the crater was clear - a sketch was provided. A BAA Lunar
Section observation.Cameron 2006 Catalog Extension ID=339 and weight=3.
ALPO/BAA weight=3.
Apianus D On 2011 Oct 03 UT 21:00-21:20 F. Power (Meath,
Ireland, 11" SCT) observed changing colours (blue, white, and
red) on the inner western rim of this crater. He changed
eyepieces and moved the scope around to look at dufferent parts
of the Moon, but nowhere else exhibited anything similar. As
another test he asked his wife to have a look without telling
her what he was seeing. She confirmed the same effect. 5 digital
camera images had been taken. Most of these were out of focus
and the first one was saturated, however one of them showed a
approximately 35 km long, by 11 km wide (at the north) lopsided
carrot shaped orange colour to the western rim of Apianus D. No
similar strong colour could be seen anywhere else on the image,
nor on the other 4 images. This TLP is being given an ALPO/BAA
weight of 1 as the Moon was low, but an image taken looks
interesting.
On 2001 Apr 29 at UT 20:50 R. Braga (Italy) reported that without any
filter, the brightness of the east wall of Torricelli B was halfway
Torricelli C (faintest) and Moltke (brightest). By insering a Wratten
25 red filter though, the crater was slightly more evident. However
using a blue Wratten 39A filter, the crater vanished completely, whilst
Toricelli C remained. The ALPO/BAA weight=3.
Near Ross D (24E, 11N) 1964 Mar 21 UT 05:00-06:20 Observed by
Harris, Crow, Cross (Whittier, CA, USA) - negative confirmation
from Las Cruces. NASA catalog weight=0 (unreliable). NASA catalog
ID #805. ALPO/BAA weight=1.
On 1983 Mar 21 at UT 21:05-22:00 P. Horne and J. Horne (Hertz, England,
UK, 11" reflector, x180 and x330) found that Mons Piton (totally
illuminated and brightest feature on the Moon - but no variability) was
brighter than Aristarchus (would have been if it had been in sunlight)
and the mountain was contained within a circular illuminated patch.
"Brilliant white and no shadow. Size ~16km." There was no details
visible but the adjacent features had distinct shadows. Hutton was also
observing. Foley examined the photographs and believes that they are
inconclusive. D. Mansbridge was photographing the Moon at 19:30UT and
detects Piton but it is not bright. However in a photograph taken by D.
Mansbrdige and 20:30UT the mountain is much brighter than any other
sunward facing slopses on the northern part of the Moon's terminator.
R. Mosley had been observing earlier at 18:10-19:40 and although
finding the mountain to be shining briliantly beyond the terminator, he
also comments that this is normal. Cameron though has seen the
photographs taken and thinks it might be a real TLP. The Cameron 2006
catalog ID=208 and weight=5. The ALPO/BAA weight=2.
On 1984 Apr 08 UT 19:50 Mobberley (14" reflector, x194, seeing
III-IV, Transparency Fair-Poor, Cockfield, UK) found that
Torricelli B's shadow was 1/2 the way across the floor, which
was normal, but that there was a very dar grey/brown shroud
around the carter, out to several radii.
The ALPO/BAA weight=1.
On 1988 Nov 16 at UT 18:20 M.C. Cook (Frimley, UK) observed that a ray
north east of censorinus appeared to be very diffuse and this did not
change during the observation. This was odd because proclus ray
material remained clear. The apron material of Censorinus was diffuse
E-W and the northern part was dull, but not fuzzy. The Cameron 2006
catalog ID=340 and the weight=3. The ALPO/BAA weight=2.
On 1988 Nov 16 at UT 18:20 M.C. Cook (Frimley, UK) observed that
Torricelli B changed in brightness (at times), but thinks that this was
due to atmospheric transparency. The Cameron 2006 catalog ID=340 and
the weight=3. The ALPO/BAA weight=1.
On 1980 Apr 22 at UT20:30 R.Rohslberger (Hittfield, (near Hamburg) West
Germany, 8" reflector, x170 25mm occular used, 300mm focal length?)
took some photographs using projection. One of these recorded an
apparent "ejecta curtain". Cameron considered lens flare, but the other
photographs did not show this. If real then the plume was at a height
of ~40km and the ray was ~130km. Cameron concludes that this was an
impact photograph. The Cameron 2006 catalog ID=90 and the weight=5. The
ALPO/BAA weight=3.
Alphonsus 1952 Nov 24 UT 18:00 A.P. Lenham (Swindon, UK, 3-
inch efractor x120) noted that the usual dark spots were not
visible, but floor ridges and craterlets were surperbly seen.
This may not be a TLP but has been given a TLP category as it
is a curious appearance and needs to be verified on a repeat
repeat illumination apeparance. ALPO/BAA weight=1.
On 1987 Jan 07 at UT19:10-20:30 H.Miles of Cornwall, UK saw two bright
patches were seen in Earthshine at clock positions of 4 (this patch was
defined by the dark limb and the brightness faded inwards to the disk,
over a short distance. "Centred at 60 deg along the limb from the north
- a sketch showed approximately 10-15 deg along it") and 5:30 (this
second patch was smaller and not so bright as the first patch - it was
west of the north pole. P. Foley (Kent, UK) also detcted the patches
and said that one was not far from the sunrise terminator.
The Cameron 2006 Extension catalog gives this TLP an ID of 291 and a
weight of 2. The ALPO/BAA weight=2.
Plato 1789 Jul 30 UTC 21:00? Observed by Schroter (Lilienthal, Germany)
NASA Catalog Event #61, NASA Weight=2 (slightly low) Event described
as: "Soon after sunrise saw a kind of fermentation on the floor which
clearly resembled a kind of twilight, (due to some kind of aberration
unknown to the observer?)" For further details see reference:
Middlehurst, B.M., Burley, J.M., Moore, P.A. and Welther, B.L., 1968,
NASA TR R-277.
Eratosthenes 1952 Nov 25 UT 16:30 A.P. Lenham (Swindon, UK, 3-
inch refractor x150, Definition Good) noted that there was
faint/slightly bright detail inside the interior shadow -
observer comments "presumably peaks of central mountains & W.
Wall ridge, but very faint" - however this is worth checking
out. ALPO/BAA weight=1.
On 2009 Nov 25 UT18:42-21:03 P.Abel, T.Little and C.North (Selsey, UK,
15" reflector, seeing II-III, transparency very good), all saw visually
a brownish tinge on the north west rim of Eratosthenes crater. P.Abel
made a sketch and T.Little took some high resolution CCD images, some
of which were through coloured filters. Checks were made for spurious
colour, but none was seen elsewhere on the Moon. The eyepiece was
changed but this made no difference. M.C.Cook (Mundesley) was observing
with a smaller scope at the same time, but saw no colour, however
observing conditions were worse. W.Leatherbarrow (Sheffield, UK) was
observing with a instrumenet mid way in size, and saw a brownish tinge
in the NW rim area, but saw a similar colour elsewhere and put this
down to spurious colour. Normally multiple observers seeing the same
thing would result in a weight of 4, however as this was only observers
at Selsey and some of the evidence contradicts, I am allocating an
ALPO/BAA weight=3.
Pallas-Schroter 1953 Nov 13 UTC 02:00 Observed by L.Stuart (USA)
"Saw and photographed a bright spot on term. between these two
craters. Used Kodak 103aF3." NASA catalog weight=5 and catalog
ID #559. ALPO/BAA weight=5.
On 2012 Aug 25 UT1944-1952 Eratosthenes crater was imaged by C.
Galdies (Malta,Nexstar 8SE, Philips SPC 900NC camera). 4
Registaxed images were produced covering 19:45, 19:48, 19:49,
and 19:51. All but the first image, once first order spurious
colour had been removed, showed orange on the shaded terraces on
the western illuminated rim (similar to what Paul Abel and
others saw in 2009, albeit just confined to the NW rim), and the
interior floor shadow was slightly smaller in red light. However
orange colour was also seen on the eastern side of mountains to
the south of the crater, which infers that the spurios colour
removal did not fully acomplish its main goal. The effects were
not caused by the registax software as the orange colour is
visible on individual images. Although probably the colour is
not lunar in orgin, its explanation is not fully explaianed,
therfore an ALPO/BAA weight of 1 is used for now.
On 1969 Nov 18 at UT 04:22 Loocks (Valparaiso, Chile, 12" reflector)
observed a flash of light of magnitude 12. Cameron speculates a meteor
and mentions the apollo 12 watch. The Cameron 1978 catalog ID=1214 and
weight=1. The ALPO/BAA weight=1.
North (?) (left) Cusp 1912 Jan 28 UT 00:00 (27th 20:00 L.T.) Observed
by Harris (Philadelphia? Pennsylvania?, naked eye?): Intensely black
curved object 400x240km, shaped like a "crow". Cameron 1978 weight=1
(very low) and ID=334. ALPO/BAA weight=1.
Eratosthenes: On 2017 May 04 UT 21:50-22:10 N. Longshaw (BAA,
UK, 78mm APO refractor, x125 & x175, seeing II-III,
transparency Good). A brownish (orange) tint was seen on the
inner NW wall light terraces - this was immediately obvious
when first looking at the crater, but as time progressed the
effect became less bright. Other craters were checked for
similar coloured tints, but none were seen elsewhere on the
Moon. UAI observers in Italy (F. Taggogna & A. Tonon) had been
imaging the region in colour 17:57-21:47, but their images do
not show any colour on the inner NW rim terraces, the their
last image is 3 min before Longshaw saw the colour. The
ALPO/BAA weight=2.
On 1936 Oct 25 at 01:35 UT W. Haas (Alliance, OH, USA, 12"
reflector) saw small bright spots on the floor of Eratosthenes,
(Pickering's atlas 9A, col. 30deg, shows no spots - according to
Cameron). Cameron 1978 catalog TLP=417 and weight=4. ALPO/BAA
weight=1.
Aristillus 1939 Jul 26 UT 02:30 Observed by Haas? (NM?, USA, 12?"
reflector) "Dark area to W. part of floor was I=3.7. (see #450, 459 &
461). Used diff. telescopes but can not explain difference)" NASA
catalog weight=4 (good). NASA catalog ID #454.
Copernicus 1966 Mar 01-02 UT 22:06-09:45 Observed by Lovell (Auburn,
OH, 4" refractor, x120m S=E, T=3.5) "As sun rose higher, west (ast.?)
outer wall was bathed in a soft viol. color -- not in evidence on flat
ground below the wall" NASA catalog weight=3, NASA catalog ID #922.
Alphonsus 1969 Nov 19 UT 03:30 Observed by Argus/Astronet (CA?, USA)
Brightening in W. rim & S. central floor, seen by 2 obs. (Apollo 12
watch)" NASA catalog weight 3 (average). NASA catalog ID #1219.
Plato 2005 Dec 10 UT 20:46 Observed by Brook (Plymouth, UK, 4"
refractor. Conditions excellent with the Moon at a high altitude) "2
second duration white flash seen on the floor of the crater" - BAA
Lunar Section Report.
Daniell 1979 Jun 05 UT 20:15-21:10 Observed by Price (Camberley,
England, 152mm reflector x64 and x128, seeing III, transparency good)
"Obscuration seen" BAA Lunar Section report.
Daniell 1979 Jun 05 UT 20:15-23:00 Observed by Price (Camberley,
England, 152mm reflector x64 and x128, seeing III, transparency good)
observed that Posidonius lacked sharpness.
Plato. 2024 Nov 11 UT 20:33-20:52. T.Smith (Codnor, UK - 16
inch Newtonian, seeing IV) the inner northern rim was an
orange-white colour and this faded, and had vanished by 20:52.
Observation ceased at 20:56. the effect was not present
earlier at 17:49-18:04, nor during a visual check at
23:14-23:24. No other features on the Moon exhibited this
effect at the time. Colour imagery by C.Longthorn at 20:14 and
A.Cook at 20:54 failed to detect any colour in this region,
but these lay outside Smith's observing window. ALPO/BAA
weight=1.
Bullialdus 1979 Jun 05 UT 22:00-23:00 Observed by Cook M.C.
and J.D. (Frimley, UK, 12-inch reflector, Seeing III-IV, good
transparency). MC Cook observed internittently over this time
period (due to cloud) and found the crater sharper in a blue
filter than in a red filter. No obscuration seen apart from a
darkish patch on the SW rim and spreading over onto an area
surrounding the rim, which she took to be shadow, though the
main shadow was along the east rim of the crater. JD. Cook
observed an orange colouration seen on eastern and the cleft
on the SW rim. Dark area seen on southern floor of crater,
south of central peak. ALPO/BAA weight=1.
On 1981 Apr 15 at UT06:27-06:40 D. Louderback (South Bend, WA, USA
using a 3" refractor x134 and S=4.5-5 and T=5-0) saw a bright spot on
the western wall of Eimmart (sketch supplied) have an unusual
brightening and shade. Variations occurred over 2-3 minute intervals.
Louderback commented that the spot looked like a flare with its apex
located at the crater wall and there was some blurring effect on the
spot - it decreased in size during the phenomenon. Seeing worsened
later. Apparently on the 18th and 19th of April everything was back to
normal. Cameron comments that there is no bright spot on the Moon at
this location. Lunar Orbiter IV plates 192-3.2 shows evening
conditions. Cameron 2006 Catalog Extension TLP ID=130 and weight=3.
ALPO/BAA weright=3.
G. Ward (a lunar observer for 15 years) observed an area just south
west of Mersenius C to be blurred and in a greenish cloud. The green
colour was more like that of dead grass than one gets from a neon bulb.
The effect was seen from 04:50-04:57UT, but could have been going on
before it was first noted at 04:50-UT. Seeing was 6-7/10 4" Refractor
(2 element). refractor had been used hundreds of hours before (over a
10 year period) with no similar colour was seen. The observer checked
other areas but did not see any similar effects. They also rotated and
changed eyepieces, but this made no difference to the TLP. The TLP site
seen was picked up on an image taken earlier at 04:47UT by W. Bailley,
from Sewell, NJ, USA. Unfortunately the area concerned, a mountain on
the image, was saturated and so we cannot tell if a colour was present
there and the seeing was poor.
Torricelli B 2005 Jan 22 UT 01:00 Observed by Serio (Houston, TX, USA,
6" Cassegrain, x150 and x180, Seeing 3, high deck of Cirrus clouds)
"Torricelli B hard to make out in the videos taken, but images taken
through cloud. A check on the image received by the coordinator shows
that Torricelli B is in fact visible, but perhaps not very bright. A
later observational sequence of images by Raul Salvo (Montevideo,
Uraguay UT 03:15-03:23) showed similarly that Torricelli B was dark,
and there was some brightness variability although the
background setting on these was low" An ALPO report.
At 03:30UT observer noticed a hint of yellow colour
on the floor of the crater and by 03:57UT the south
east and central parts of the floor and the circular
feature on the south west floor had turned a deep
yellow colour. The rest of the crater remained colourless.
Other craters also remained colourless. By 04:05UT the colour
was fading and by 04:15UT it was gone. Maurice Collins
in New Zealand took some low resolution colour images about
4 hours later but these failed to show any yellow colour.
Zac Pujic obtained colour images at a different time of
natural surface colour on the Moon and finds that Bullialdus
does actually have a natural yellow cast to most of the floor.
However this does not explain the variability in colour strength
seen by Robin Gray. ALPO/BAA weight=3.
Observed by Firsoff (Somerset, England, 6.5" reflector? x240) "Red
glow." NASA catalog weight=4 (high). NASA catalog ID #573.
On 1987 Jan 11 at UT 18:15-23:00 P. Grego (Birmingham, UK, 6"
reflector, seeing=III) sketched Aristarchus crater and saw two
luminous circular patches on the exterior west wall - these
were less bright than the inner wall but brighter than the
outer wall. The Cameron 1978 catalog ID=292 and weight=5.
ALPO/BAA weight=2.
On 1987 Jan 11 at UT P. Moore (Sussex, UK) found the the floor of Plato
was much more drk than the adjacent Mare Imbrium. Furthemore there was
a blurring of detail over the northeast wall and onto the nearby floor.
detail elsewhere in the crater was OK. By 23:00UT there was less lack
of detail effects. M. Cook (Frimley, UK) at 21:55UT noted the obscured
area but decided that it was narrower than the same effect one month
ago and suspected that she may have been observing towards the end of
this TLP. The effect gradually dimmed between 21:55 and 22:45UT. Other
craters were normal. G. North was affected by poor seeing conditions.
Davies detected a slight obscurtion on the north east corner - it was a
misty gray feature at x200. The Cameron 2006 catalog extension ID was
292 and the weight was 5. Tha ALPO/BAA weight was 4.
On 1889 May 11 at 22:00? UT an unknown observer saw an ink black spot
on the rampart of Gassendi. It had not been seen before ar at the next
lunation or indeed ever again. Cameron 1978 catalog ID=261 and
weight=3. ALPO/BAA weight=2.
Cobra Head 1949 Feb 10 UT 00:00? Observed by Thorton (Northwich,
England, 18" reflector) "I was examining the Cobra Head of the Schroter
Valley, when I noticed what seemed to be a diffuseed patch of thin
smoke or vapour, apparently originating from the valley on the E. Side
where the landslip is, and spread over the edge on to the plain for a
short distance. Every detail of the edge of the valley was perfectly
clear and distinct except where this patch occurred, but there the
definition was poor and very blurred" NASA catalog
weight=4 and catalog ID #515. ALPO/BAA weight=1.
Bullialdus 1974 Sep 27 UT 22:45-23:40 Observed by Findlay, Ford
(Dundee, Scotland, 10" refractor, 150x, 180x, filters) "Saw yellowish-
orange color in crater. After clouds passed at 2300h color still there
& gave a slight blink which no other craters did. Not seen in red
filter, dark in blue. Ford saw it along ridge fr. c.p. to SW wall.
Alert did not bring confirm. as clouds intervened for all others." NASA
catalog weight=4. NASA catalog ID #1394. ALPO/BAA weight=3.
Torricelli B 2005 Jan 22 UT 03:15-03:23 Observed by Raul Salvo
(Montevideo, Uraguay UT 03:15-03:23) showed that Torricelli B
was dark, and there was some brightness variability although the
background setting on these images was low and seeing could
account for the brightness variation? An ALPO report.
On 1990 Oct 1st at 00:44-01:24UT D Darling (Sun Praire, WI, USA)
observed that Gassendi still had a blink effect when viewed through
blue (Wratten 38A) and red (Wratten 25A) filters. No effect was seen on
Aristarchus. Gassendi was brighter in the red filter and this was
confirmed by Weier. Sketches were made and brightness measurements
taken. Both observers used a 12.5" reflector x159. At 01:00UT the NW
wall was 7.5, the SW wall 8.0, the S. wall 7.5, the floor 6.0, the
outer E. wall 8.0, the N. floor 5.5. Gassendi A W. wall was 9.5,l
Aristarchus W. floor was 8.0, NW wall 8.0, shadowed floor 0.0, E. outer
wall 7.0, NBP 5.5, area between Aristarchus and Herodotus 6.0, and the
comet like tail: 8.2 on the E. and 8.5 on the W. The Cameron 2006
