Leibnitz Mountains 1955 May 24 UT 21:30-22:00 Observed by Firsoff
(Somerset, England 6.5" reflector, x240, seeing = very good). "Changing
lights over a period of time, lunar aurora? Beyond cusps were 2 bright
pts. 1 was sparkling and dancing and weaker intensity. Then a faint
beam detached itself & shot up vertically, becoming more intense but
faded at the base. Total length @ 160 km. Endured for > 2 s. Due to
telescope spider or lunar aurora?" NASA catalog weight=4 (good). NASA

In 1965 Jul 02 at UT 04:20-05:50 Albert and Welch (Azuss, CA, USA, 8"
reflector, x375) and Emanuel (West Covina, CA, USA, 4.5" reflector)
observed 4th magnitude star-like flashes to blotches in Aristarchus, in
ashen light. Cameron says that this is independent confirmation and
also that the date in MBMW is 7/1/65 which is local time + 2nd UT. The
Cameron 1978 catalog ID=881 and weight=3. The ALPO/BAA weight=3.
On 1981 Jan 09 at UT 00:30-00:45 D. Darling (Sun Praire, WI, USA,
12.5" reflector, seeing=8/10, transparency clear, but Moon low at 7 deg
above the horizon) found that despite Aristarchus being seen to be
bright in Earthshine, it was not as bright as Menelaus and Manilius.

On 1981 Jan 09 at UT 00:30-00:45 D. Darling (Sun Praire, WI, USA,
12.5" reflector, seeing=8/10 and the sky was clear - the Moon was at
7deg altitude though) saw that Manilius outshone Aristarchus - or was
it that Aristarchus was especially faint tonight? Manilius could be
seen even when the illuminated part of the Moon was in the eyepiece.

In 1949 May 02 at UT 03:30-04:00 Barcroft (Madera, CA, USA, 10"
reflector, x96) observed in Aristarchus crater, in Earthshine, a
dull glow -- silvery phosphorescence.This was not visible for 30
min prior. Cameron comments that this is a confirmation of
Wilkins TLP from a few hours earlier? The Cameron 1978 catalog
ID=519 and weight=5. The ALPO/BAA weight=2.
In 1965 Jul 03 at UT 04:25-05:34 Emanuel (West Covina, CA, USA, 4.5"
reflector) observed 4th magnitude star-like flashes and pulsations
coming from Aristarchus. Cameron says this confirmed and that the date
in MBMW is 7/2/65 which is local time = 3rd UT. The Cameron 1978
catalog ID=882 and weight=3. The ALPO/BAA weight=3.
Proclus C region 1985 May 23 UT 17:41 Photographed by Kolovos (observer
from Thessoloniki, Greece, observing site near Bafra Serrain, Greece,
4"refractor, seeing excellent) "Observer took a series of expousres on
a portable scope of the Moon. On one of them a very bright slightly
elliptical spot was seen. Spot was very close to the Proclus C crater.
Upon analysis it was claimed that the spot of light had rotated the
direction of illumination of shadows in adjacent craters - however
subsequent analysis casts doubt on this. Papers on this report
were published in Icarus. Rast and Maley suggested that it was sun
glint off a spinning US ex-military weather satellite that just by
chance came across the field of view of the Moon a few tens of seconds
around the time of the photographed flash. Was this a coincidence or
not? If it were a satellite sun-glint then the satellite would have to
be tumbling incredibly fast in order for the flash to be so sharp in
the photograph - so the satellite explanation is not completely 100%
confirmed." The Cameron 2006 catalog ID=273 and the weight=5. The
ALPO/BAA weight=2.
On 1990 Jun 27 at UT02:17-03:00 D. Darling (Sparta, WI, USA, 3"
refractor, x36) reported that the crater had "Flared up at 0225 as a
point of light then went down" - the effect was fairly brief.
Earthshine was quite clearly seen and all features elsewhere were
normal. The Cameron 2006 catalog ID=405 and the weight=0. The ALPo/BAA
weight=1.
On 1971 Jul 26 at UT 21:40-22:05 daSilva (Paranaiba, Brazil, 13"
refractor, x224, seeing=good and transparency=fair) observed two
brilliant points in Aristarchus - the right one was the more
brilliant of the two. The observer says that this was not a TLP,
but is similar to other reports (Apollo 15 watch). The Cameron
1978 catalog ID=1300 and weight=1. The ALPO/BAA weight=1.
In 1965 Jul 04 at UT 03:53-05:59 Gridley, Welch (West Covina, CA, USA,
4.5" and 8" reflector, seeing=excellent), Albert (CA, 8" reflector,
x375) and Emanuel (8" reflector) observed star-like flashes in
Aristarchus crater. Cameron says this confirmed and that the date
in MBMW is 7/3/65 which is local time = 4th UT also but is in error due
to misreading of handwriting. The Cameron 1978 catalog ID=883 and
weight=3. The ALPO/BAA weight=3.
On 1965 Oct 30 at UT 0200 Eastman (Palos Verdes, CA, USA, 12"
reflector) observed a brightening in Aristarchus in ashen light. The
photographs that were taken show it. The phenomenon was seen each
lunation since July. The Cameron 1978 catalog ID=908 and weight=5. The
ALPO/BAA weight=2.
McClure vicinity 1976 Apr 04 UT 19:36-2009 Observed by McKay
(England, 3" refractor, x160), Savill (England, 10x50
binoculars), Moore (Sussex, England, 15" reflector, x360, seeing
II), Buss (England, 6" reflector), Brady (England, 8"
reflector), Ross (England), Foley (Kent, England, 12" reflector)
"Noted a fuzzy, glowing spot at 1936h at 160x. 2 min later, spot
grew larger & flashed up to very bright. Changed power to 106x,
& 80x, still vis. Spot faded 10 m later, then suddenly flashed
up again. 5 m later it faded again & disappeared at 1959h. At
2006h returned to fuzzy, glowing spot then disappeared at 2009h,
never to reappear. Some obs. confirmed, others did not. Photos
afterward don't show anything, nor did blink aftwerward." Moore
though nothing unusual. NASA catalog weight=5. NASA catalog ID #
1431. ALPO/BAA weight=3.
On 2009 Mar 01 at UT 18:50-21:00 G. Smith (East Yorkshire, UK, 127mm
Maksutov Cassegrain telescope with zoom eyepiece and later a Plossl
eyepiece) observed an area between Plato and Sinus Iridum to be glowing
as a bright nebulous patch. It was brighter than anything else in
Eartshine. A change in eyepiece did not affect the appearance of the
nebulous patch. The patch had faded somewhat by 21:00UT. The observers
brother attempted to observe the patch through a 114mm reflector at
20:30UT but the optics were of poor quality and the effect was not
seen. BAA observers were alerted, but only after the event had faded -
they made observations from 22:00-23:46 UT but failed to detect
anything unusual in the region concerned. The ALPO/BAA weight=1.
This may have been a mis-identification with Aristarchus - however
we cannot be 100% sure.
Posidonius 1821 Apr 07 UTC 18:00? Observed by Gruithuisen (Munich,
Germany) "Small bright crater in it was shadowless. Schroter also saw
it shadowless several X" NASA catalog weight=4 (good). NASA catalog ID

On 1984 Jul 04 UT 22:08-23:09 Foley (12" reflector, Kent, UK) found
that Censorinus gave a low brightness CED reading of 58%, despite all
other measured points on the Moon as being normal. M. Cook (Frimley,
UK) found Censorinus to be extremely dull compared to Proclus. J.D.
Cook (Frimley, UK) found Censorinus to be quite dull, barely above
background levels. The Cameron 2006 catalog ID=246 and the weight=4.
The ALPO/BAA weight=3.
On 1984 Jul 04 at UT 22:05-23:09 Richardson (Swinton, Yorkshire, UK,
seeing=VE) found that a peak west of Theophilus crater had a deep blue
colour, and this was strange because no colour was seen elsewhere on
the Moon. Foley (Kent, UK, 12" reflector), once alerted, found a dome
east of Kant? to be blue, and likewise no colour was seen elsewhere on
the Moon. Cameron 2006 catalog ID=246 and the weight=4. The ALPO/BAA
weight=3.
On 1984 Jul 04 UT 22:08-23:09 Foley (12" reflector, Kent, UK) found
that Torricelli B was a much lower brightness than was expected and
this remained the case for the rest of the lunation. The Cameron 2006
catalog ID=246 and the weight=4. The ALPO/BAA weight=1.
Albategnius 1972 Jun 18 UTC 19:20-19:25 Observed by Schnuchel (13.25E,

Censorinus 1984 Jul 05 UT 21:05-21:25 Observed by Cook (24" reflector
with line scan photodiode array at Mill Hill observatory, London) "Two
line scan photodiode array images were taken which used the motion of
the Moon to build up an image. The first image at 21:25UT did not
include all of Censorinus, but the part that it did include was not
very bright. The 21:25UT image did include all of Censorinus and the
crater was bright, including the part that was just visible in the
previous image. Possibly the seeing was worse at 21:05? and this could
explain the brightness descrepency, but it is worth checking again by
taking images at the same illumination conditions" BAA Lunar Section
report. At 21:17 M. Cook (Frimley, UK) found Proclus to be brighter
than Censorinus (more so than the previous night) and obtained variable
readings for Censorinus. Cameron 2006 catalog ID=247 and weight=3.

Proclus 1984 Jul 06 UT 20:29-20:43 light green spot observed by Madej
(England) in the central region. No colour seen elsewhere. At 20:10
Foley (Kent, UK, 12" reflector) had seen a small extending of darkening
in the south east floor (not present 2 hours before) and a lot of fine
detail - though everything was normal again by 22:50UT. At 22:15 Amery

On 1979 Sep 29 at UT10:00-12:00 S. Turner (Maryborough, Australia)
observed a strong beacon like flash in white light that moved back and
forth in the east wall of Plato (very bright) and Mons Pico. tried
changing eyepiece and the field of view, but this wasn't the cause of
the effect. A check at 11:07UT did not show the effect, but it was back
again by 11:18UT being more pronounced at Mons Pico than the east wall
of Plato. SSW of Mons Pico was also blinking slightly. At 11:32 the
blinking effect was irregular 5-10 sec and this continued until
12:00UT. Cameron 2006 catalog ID=71 and weight=0 but she suggests
atmospheric scintillation as a cause. ALPO/BAA weight=1.

On 1871 Nov 20 at UT 17:30-19:30 H. Pratt (UK) saw one of the most
spectacular TLP obscurations that he had ever seen in Mare Frigoras. He
observed a kind of haze around the north west (NE?) slopes of Plato.
This effect was not seen elsewhere and all objects in Mare Frigoris
were indistinct or veiled. By 18:30 the effect was modified and by
19:30 very little trace was seen. Ref. from Corliss.

90mm Quastar Cat., Seeing III, transoparency hazy) and by Moore
(Selsey, England) "Following an alert call by Miles concerning the
crater Proclus looking different, Cook observed a circular dark patch
that filled about half of the eastern half of the crater floor. To cut
down the glare a blue filter was then used and a slightly less dark
area was seen extending from this in a southerly direction. 8 rays were
seen. The dark patch was confirmed by Patrick Moore. However David

A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and
definition fairly good. Observer noticed that the Mare seemed covered
with a close network of innumerable streaks, and spotted with countless
numbers of light specks, so that it would hardly be possible to
delineate them all in one night. The spots and streaks together must
have numbered ~1000. The observer had never seen anything like the
number of spots and streaks. Peirce A, was not at all easy to se and
neighboring spots almost as bright made it difficult to distinguish
which one was Peirce A. ALPO/BAA weight=3.
Plato 1966 Sep 25 UT 23:12-23:35 Observed by Moseley (Armagh, Nortern
Ireland, 10" refractor, x140) "Eng. moon blink sys. blinks inside the

quite good) noticed a faint red glow at the south west wall of Gassendi
covering a span of about 35 deg arc. The observer had some doubts about
this because they were using a small telescope, but thought that they
ought to report it, just in case. A BAA Lunar Section report. ALPO/BAA

On 1982 Aug 01 at 00:00-01:00 K. Marshall (Medellin, Columbia, 12"
reflector, seeing I-II) noted shading on the east floor of Plato that
was apparently lighter than the rest of the floor and this was seen at
both low and high magnifications. Foley notes that this was unusual.
There were three craterlets visible on the floor - the central one was
the brightest. Cameron 1978 catalog ID=178 and weight=3. ALPO/BAA

On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector)
and at the same time Doherty (Sussex, UK, 15" reflector) observed a
strangely bright and pink/red north rim of Aristarchus crater during
UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT.
M.C. Cook (Frimley, UK) found the northern wall to have a red/purple
colour but the effect vanished after 50 minutes. Cook also saw a "V"-
like notch in the NW crater shadow and this appeared to be bigger than
normal. G. North (Sussex, UK) saw a tinge of pink colour on the
northern rim and a bit later a "ruby red" colour on the north-west wall
- again this effect lasted 50 minutes. Moseley verified the colour.
Finally M. Hather (Yorkshire, UK) suspected the north wall of
Aristarchus to be blue in colour. Cameron suspects that this TLP is not
spurious colour because it is in the wrong place. The Cameron 2006
catalog ID=276 and the weight=5. The ALPO/BAA weight=4.

10" f/4 reflector, x200, seeing 6, Transparency 3 - scattered
cirrus) observed visually (depicted in sketch) the two closely
spaced NW wall dark bands) to have a rusty-red hue. The colour
of these bands did not change over the period of the observing
session. Images were taken, but resolution and image S/N is
not sufficient to resolve separate bands here, or to detect
colour. The ALPO/BAA weight=2.
In 1950 Aug 25 at UT 10:55 T.Saheki (Osaka, Japan) observed a

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

On 1980 Sep 24 at UT 21:13-23:50 P.Moore (Selsey, UK) at 22:45 saw loss
of detail in the north west wall, especially in red light, but also
slightly in blue light too. By 22:48 there was activity on the crater
floor i.e. the four bright spots were visible in white light but not in
red. In blue the central spot was seen and there were dark radial
streaks to the south wall and south east. At 22:50 there was a loss of
detail. Other craters were normal. At 23:08 the floor was dark in red,
but some details were visible in blue. the effect had finished by
23:35. At21:34 J-H Robinson found Plato to be normal and no blinks,
though floor clearer in red than in blue, however the floor detail had
gone by 21:57. Blair suspected a dusty patch in north of Plato,
especially in red light. at 21:57 and it started spreading at 21:13,
then east at 21:15 and then north. Though it faded at 21:25 but was
back again at 21:35, and Moon blink colour filters still gave a
reaction at 21:50 - the TLP remained strong until 23:50UT. The Cameron
2006 catalog ID=110 and weight=5. The ALPO/BAA weight=4.
On 1980 Sep 24 at UT21:34 J-J. Robinson (Teighmouth, Devon, UK, 10"

colour on the crater floor from 19:10-20:05, but suddenly the floor
colour changed to a slate blue-grey colour from 20:05-21:45UT. Colour
was not detected elsewhere. CED brightness measurements taken - these
were normal for Proclus, Mons Pico, Mons Piton and Tycho, but for
showed that Aristarchus varied in brightness. Crater Extinction Device

On 1980 Sep 25 at UT20:20-22:14 P. Moore (Selsey, UK) noticed that the
central craterlet was more visible in red than in blue. There was also
a streak on the floor that was "shifted to S & W." The floor was dark
and Mons Pico was bright. Peters found Plato's floor (and central
craterlet) to be dark, and darker in blue than in red, however he was
suffereing from spurious colour at his observing site. Cameron 2006

Torricelli B 2002 Oct 23/24 UT 23:25-23:52 Observed by Clive Brook
(Plymouth, UK, 60 mm OG x120 + prism) "Observed that Torricelli was
very diffuse and Tor B showing shadow ? observer considered a shadow
perhaps a little surprising this far from the terminator. Nothing
unusual seen by M.Cook at 23:52UT or by A Cook at 00:40-00:52 and
indeed other craters did appear to have shadows this far from the

14" Cassegrain, seeing variable, transparency misty) found that
the central craterlet on the floor of Plato was not visible,
despite it being visible under similar colongitudes on other

10.25" reflector, x250, Wratten 44a and 25, seeing II) noted
that Aristarchus was surrounded by a dark area in the blue
filter. They did not regard this as a TLP at the time. However
because Aristarchus is surrounded by blue material in real life,
this should have been brighter? For this reason, despite the
observer regarding this as a negative TLP, an ALPO/BAA weight=1
has been applied.
On 1891 Sep 25 at UT 20:00 Pickering, based at Arequipa, Peru, and
using a 12" reflector, saw in Schroter's Valley and the vicinity
"Varitions in vapor column. Time estimated from given colongitude)."
Cameron 1978 catalog ID=273 and weight=1. ALPO/BAA weight=1.
On 1977 Nov 03 at 22:13UT P.W. Foley (Kent, UK, 11" reflector, x285)saw
some flickering in Gassendi (Clouds on limb - according to Csmeron?).
The Cameron 1978 catalog ID=18 and weight=1. The ALPO/BAA weight=1.
On 1981 Dec 19 at UT 01:00-05:00 E.V. Arsyukhin (Moscow, Russia, 3"
reflector) observed that Plato was consdierably brighter than
Aristarchus by several times. The image quality was very clear. The
Cameron 2006 catalog ID=161 and weight=3. The ALPO/BAA weight=2.
Aristarchus and Cobra Head 1968 Jul 18 UT 00:50-01:30
Observed by Moseley & Corvan (Armagh, N.Ireland, 10"
refractor, x255) and by Moore (Selsey, England, 3" refractor,
x 120) "Distinct red glow & obscur. 1st at 0050 S. of C.H. &
same size. At 0052h saw color on S.wall of Aris. Both
persisted till 0100h then both (faded, then brightened, then
faded. Plato, Gassendi & Kepler checked with neg. results.
Obscured areas reached greatest extent at 0125h wgen it was
1/2 size of C.H. & SSE (ast. ?) of it. Moore was alerted to
it & saw it in blink, but not vis. at 0107-0220". NASA
catalog weight=5. NASA catalog ID 1085. ALPO/BAA weight=4.
On 1971 Jun 16 at UT 07:08-07:09 Raimundo Nonato da Silva
(Parnaiba, PI, Brazil, 9.5" reflector, x90, seeing=good)
observed during a lunar eclipse that the Straight Wall
surroundings were darker than an observation from two days
earlier. At 07:09UT tonality became clearer. As dawn was in
progress and atmospheric turbulence, not sure if it was a TLP?
Other features were normal. The Cameron 1978 catalog ID=1297 and
weight=1. The ALPO/BAA weight=1.
Closest parts of the Moon at Saturn appearing from
occultation were dull and hazy. Was this an effect of
the lunar atmosphere or a high haze and halo around the Moon?
Cameron's 2006 catalog extension gives this an ID No. of 3
and a weight of 1. The ALPO/BAA catalog weight is also 1.
Aristarchus 1973 May 27 UTC 01:09-01:56 Observed by Theiss (51N, 9.67E,
75mm reflector) "3 diameters of Aristarchus around its center: orange
bright area from 01:09-01:56" Ref: Hilbrecht & Kuveler, Moon & Planets
Vol 30 (1984) p53-61"
On 1966 Sep 09 at UT 21:00-21:30 Cave (England, UK, 6" reflector, x364,
S=F) observed that the flor of Wargentin was a very dark gray, two
shades darker (on scale of 1-10) than the floor of Nasmyth and nothing
to be seen on it even along the ridge. A drawing was made. The Cameron
1978 catalog ID=976 and weight=3. The ALPO/BAA weight=2.
Near Gassendi 2003 Aug 23 UT 09:00 Observed by Weeks (USA, 88deg 33'
W, 22deg 33' N, 20cm reflector) "Observation period ~30 min, terminator
straight down middle of Gassendi, very bright spot seen glaring on
the dark side ~2-3 Gassendi diameters away (SW or NW?). Intense glare
unlike anything seen on Moon before. Spot did not brighten or fade. The
ALPO/BAA weight=2.
Mercurius E (76E, 48N) 2004 Aug 11 UT 18:28:27 Takamura_Y (Ogawamura
Observatory, 137:59:13E, 36:39:34N) observed a 9th magnitude impact
flash. This was verified by 2 other observers elsewhere in Japan.
The ALPO/BAA weight=1.
Aristarchus 1969 Aug 09 UT 01:00? Observed by Hiscott
(Canterbury, 12" reflector) "Bright spots photog. on E. wall
(EWBB) (crater wall seen in ashen light at this time accord.
to LION obs.). Pearce, in BAA Circ. 5 (3) says LO 4, fr. 150
shows highlights in similar areas & in Cobra Head & are due
to slopes.) Spots were on all 8 negs." NASA catalog weight=5.
NASA catalog ID #1199. ALPO/BAA weight=3.
Southern cusp obseved by H.Hill (UK) on 1984 Jul 25. Solar
Selenographic colongitude=232.6. Observer noted a dusky ill-
defined strip in Earthshine extending beyond the southern cusp
that appeared "atmospheric". Note that this is almost certianly
not a TLP but is worth checking out if the libration and solar
colongitude is similar, just to verify that this is what the Moon
normally looks like. ALPO/BAA weight=1.
Grimaldi 1938 Mar 28 UTC 09:30 Observer: Firsoff (Glastonbury, UK - 6"
reflector) - Slight greenish colour - {Note the UTC given in the NASA
catalog is 09:30 which is in daylight here in the UK - possibly the
catalog is wrong, else the observer was observing in daylight, but
worth checking out just in case}. NASA catalog ID No. #433 and NASA
weight=4 (good).
On 1790 Mar 19 UT 21:00? Schroter (Lilienthal, Germany) described in
the Aristarchus region a "Small hazy spot of light". The Cameron 1978
catalog ID=68 and weight=4. The ALPO/BAA weight=1.
