Boussingalt 1860 Apr 24 UT 20:00? Observed by Schmidt (Athens, Greece,
7" refractor) "Noted weak glows on the crater he tho't prob. due to
wall reflections on floor" NASA catalog weight=0 (very unlikely to be a
TLP). NASA catalog ID #132. ALPO/BAA weight=1.
On 1989 Apr 10 at UT01:30-02:00 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x64, seeing excellent) observed that Earthshine was not as
good as the previous night "~1/4 north shore looked unusually bright compared to other similar
features. BAA Lunar Section observation. ALPO/BAA weight=0.
Bright spot (in dark part of Moon - confirmation of Arkhipov?). Cameron
1978 catalog weight=5 and Cameron 1978 catalog serial No. 418,
Proclus 1955 May 25 UT 19:30 Observed by Firsoff (Somerset, England,
6.5" reflector x240, seing=very good) "E. (IAU?) wall equally bright in
red and green filters, dull in blue, invisible in violet. (in p.c. time
given is 0730UT, but must have been 7:30PM loc. time." NASA catalog
weight=4 (good). Cameron 1978 catalog ID=594 and weight=4. The ALPO/BAA
weight=3.
On 1980 Nov 11 at UT17:35-18:32 G. Blair (Weir, Scotland, UK) at
17:35UT immediately noted that the Earthsine was extremeley bright. All
large detail easily seen on unilluminated disk. 17:38UT a definite pale
reddish brown tinge enveloped the Aristarchus area. 17:39 seemed to be
getting larger and more intense west (IAU) side. Attempted to contact
other observers. 17:40UT Aristarchus still had a bright central peak.
17:50UT fading a little from the west (IAU). 18:00UT slight revival in
brightness. 18:15UT effect still visible when Aristarchus set behind a
high western horizon. The two sketches supplied show the illuminated
region around the crater with extension to the west (IAU). P. Foley
(Kent) found thatAristarchus was bright enough in Earthshine to be seen
with the naked eye. Telescope in operation at 18:00UT and the entire
Aristarchus region was bathed in violet/rose colour with what appeared
to be a strong ray extending to the west (IAU). Detail could be clearly
seen inside Aristarchus crater such as the central zone, west and north
wall and rim in relief from point southeat to northwest. CED measure
0.8 (white), 0.9 (blue), 0.2 (red). No other reading in Earthshine gave
a measure in red. Observation ceased by 18:32UT as the Moon was very
low. ALPO/BAA weight=3.
On 1970 Jul 07 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3"
refractor, x60, x100, x135, seeing=good) observed the following in
Aristarchus: "Similar conditions as last night (#1264) but diminished
in brightness to 40% (to 6deg bright. Real phenom. in the dimming?)".
The Cameron 1978 catalog ID=1265 and weight=3. The ALPO/BAA weight=3.
Om 1990 Mar 01 at UT 00:59-02:20 D. Darling (Sun Praire, WI, USA, 3"
refractor, x36) observed that Aristarchus could barely be seen, but at
02:15 UT it brightened by about two times. Note that brightening might
refer to Lambert - it is worded in an ambiguous way in Cameron's
catalog). The Cameron 2006 catalog ID=392 and weight=0. The ALPO/BAA
weight=1.
Om 1990 Mar 01 at UT 00:59-02:20 D. Fryback (Madison, WI, USA, 8"
reflector) observed that Lambert was a star-like point, but later saw
it brighten up (02:15UT) by two times (note that this brightening might
refer to Aristarchus - it is worded in an ambiguous way in Cameron's
catalog). The Cameron 2006 catalog ID=392 and
weight=0. The ALPO/BAA weight=1.
In 1948 Aug 09 at UT 02:40 Woodward (Toronto, Canada, sky very
clear) observed, using a telescope, a bright, bluish-white to
greyish-yellow, 3 sec duration flash in Earthshine. The flash
was between magnitude 0 to 1 if one were looking for a similar
magnitude star in the sky without a telescope. There was
possibly a very slight motion of the flash in a southerly
direction. Also there were two terminal bursts. Cameron suggsts
that this might have been a meteor? Ref: Moore, P.A. Guide to
the Moon (1953), p117. The Cameron 1978 catalog ID=508 and
weight=0. The ALPO/BAA weight=1.
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 1970 Jul 08 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3"
refractor, x60, x100, x135, seeing=excellent) observed the following at
Aristarchus: "Conditions again similar (to #1264). Brighter tonite(8
deg) than last nite. but not as bright as on the 6th. Pin pts. of light
very accentuated. The radial open hand extended fingers form not so
frequently, perhaps because of the larger crescent illum. now.".
The Cameron 1978 catalog ID=1266 and weight=3. The ALPO/BAA weight=2.
On 1885 Feb 19 at UT 19:00-20:00, Gray of England?, saw a small crater
(in it?) that was dull red with vivid contrast. The Cameron 1978
catalog ID is 247 and the weight=3. The ALPO/BAA weight=3.
Cyrillus G 1983 Aug 13 UT 20:17-20:59 L. Paynter (Radcliffe,
UK, 22cm reflector, seeing III or better, transparency good).
Cyrillus G was relatively bright and surrounded by a shaded
area. On increasing the magnification from x65 to x130 he became
aware of a diffused "carise" colouration, in and around the
crater. The colouration was similar though to other spurious
colour on the Moon, but unlike other areas affected by spurious
colour, was more diffuse and spread out and not so concentrated.
In view of some uncertainty by the observer, ALPO/BAA weight=1.
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 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.
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
#87. 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.
In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of
twilight (Cameron says also seen by Gruithuisen, Henry and others at
times). Webb gives a low weight to his own observation, saying "for
want of better optical means". The Cameron 1978 catalog ID=130 and
weight=1. The ALPO/BAA weight=1.
On 1965 Oct 30 at 23:30-23:50UT Fehring and Garris (Parasmus, NJ, USA,
using a 2.4" refractor x88, seeing very good) saw a fuzzy area --
variations in shape and distinctness, seen in an area east of Atlas
crater. A drawing was made. It was noted that no other area had a
similar effect. Cameron 1978 catalog ID=909 and weight=3. ALPO/BAA
weight=3.
On 2012 Mar 28 at UT 20:45-20:50 Two unknown Italian
observers, reported on an on-line formum that they had
independently seen a distinct glow with a comma/drop shape.
One of them moved the Moon and the glow moved with the Moon.
It is uncertain how experienced the observers where. A chart
was provided which shows the lcoation of the glow in the
western side of Mare Imbrium. It is just possible that this
was Aristarchus in Earthshine, though that is very slightly
further west and south than the observers reported. ALPO/BAA
weight=1.
On 1881 May 04 at UT 20:00? Trouvelot (Meudon, France)
observed an unexplained light inside Eudoxus crater. The
Cameron 1978 catalog ID=222 and the weight=3. The ALPO/BAA
weight=3.
On 1994 Apr 17 at UT02:00 R. Zit (Madison, WI, USA) whilst observing a
grazing lunar occultation, found that Aristarchus (and the surrounding
region) was glowing in Earthshine. This was confirmed by D. Weier
(Madison, WI, USA) at 02:00 UT also. The ALPO/BAA weight=1.
On 2012 Mar 28 P. Grego (Cornwall, UK, seeing II, 100mm
refractor, x132) observed a patch of light just inside the NW
rim of Menelaus on the shadowed wall or floor. Computer
visulaiztions of the illumination conditions using a digital
elevation model failed to produce this effect. ALPO/BAA weight=3.
Cepheus A 2000 Oct 04 UTC 08:15-08:50 Observer: Maurice Collins
(New Zealand, 90cm ETX) - observer noted that crater was
extremely bright - wasn't sure if this was normal and at the
time rated it as the brightest (contrasty?) crater that he had
ever seen on the Moon. Many years later he suspected that he may
have mis-identified the crater. This still leaves us with thr
problem as to why a crater should be so bright in this region,
and if so, which one? ALPO/BAA weight=1.
Pitiscus 1981 Sep 05 UT ??:?? but assumed to be AM? which would make
it 00:00-03:00UTC. Observed by Slayton (Fort Lauderdale, Florida, USA,
8" reflector, ASA 64EK7 f/170, Kodak Kodachrome) photographed a bright
glow in the crater that appeared to move. Observer also reported seeing
it visually noting that it looked gray with a tinge of red. For further
information see p266 of Sky & Telescope (1991, March). Note that
Cameron gives the date and UT at 1981 Sep 06 UT 01:00-01:30, or one day
later. I will use this date and time from now on. The Cameron 2006
catalog ID=152 and weight=5. The ALPO/BAA weight=3.
In 1982 Sep 24 at 22:45-23:40 K. Marshall (Medellin, Columbia) saw in
Theophilus an obscuration on the south west wall close to Cyrillus and
furthermore it had a red / mauve colouration (seen best in a 12mm Ortho
eyepiece). Through a Wratten 15 yellow filter the region was quite
bright. At23:40UT the obscuration faded. There was plenty of detail in
the region between Theophilus and Cyrils. The Cameron 2006 catalog ID=
184 and the weight=3. The ALPO/BAA weight=3.
On 1915 Apr 21 at UT 1800? Houdard (France) noticed a special
occurrence south of Posidonius which he took as evidence of water
vapor. The Cameron 1978 catalog ID=351 and weight=3. The ALPO/BAA
weight=2.
Albategnius 1972 Jun 18 UTC 19:20-19:25 Observed by Schnuchel (13.25E,
52.5N, 20x60 binoculars?) "Bright area at the inner N wall, diminution
of brightness well observable" S=4 T=4. Ref: Hilbrecht & Kuveler Moon &
Planets (1984) Vol 30, pp53-61.
A.S.Williams of West Brighton, UK, using a 2.75" Acromatic refractor
(x75, definition good, but it was too windy to use the 5.25") noticed
that the mare was a mass of light streaks and spots. This was not
considered unusual, but these features were unusually plain, distinct
and brught, especially the streaks. The observer could not recall
seeing the streaks so bright and clear with this instrument before, and
indeed hardly ever with the larger 5.25" telescope. The observer
continued to observe Mare Crisium on many nights for several months and
comments that such an unusual exhibition was later seen perhaps once
every 2-3 lunations. They are uncertain how much this effect depends
upon the state of the Earth's atmosphere. This TLP does not make it
into the Cameron 1978 catalog and so may not be a TLP - however it has
been included, just in case, and to try to understand what was actually
seen. ALPO/BAA weight=1.
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.
ALPO/BAA weight=2.
Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson,
Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw
something in Proclus, alerted Jamieson who saw nothing unusual
at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw
Proc. fluctuate. Red & blue filters showed some reduction in
brightness. E. edge showed darkening, but not as dark as in
shadows. 10 min later, returned to normal. (Sparks confirmed
Dean)." NASA catalog weight=5. NASA catalog ID #1267. ALPO/BAA
weight=3.
1970 Jul 11 UT 20:35-20:45 During a TLP alert for Proclus, Jamieson
saw nothing unusual, but found instead that Secchi was quite bright.
NASA catalog weight=5 (very good). NASA catalog ID #1267. ALPO/BAA
weight=1.
On 1983 Sep 15 at UT 05:20-05:24 Louderback (South Bend, WA, USA,
8" reflector and 3" refractor, seeing poor) found that the west wall of
Eimmart was unusually bright (8.3) and apparently it was almost as
bright as the "WEBS(of Aris?) at its brightest". The crater was
apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID=
228 and the weight=3. The ALPO/BAA weight=2.
2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw
Mons Pico to be incredibly bright. Adee reported naked eye visibility,
though this does not show up in later CCD images. Jarwaski saw another
nearby Mt very bright as well. This has been assigned an ALPO/BAA
weight of 1, though I suspect it is just normal for Pico to get quite
bright at sunrise.
Patches of brightness seen in the area between craters Aratus and Joy.
Seemed to the observer to be perhaps slightly brighter than one would
expect - the observer thought that their observation only barely
constitured a TLP but decided to send the report in anyway. This
has been assigned an ALPO/BAA weight of 1.
Purbach 1970 Apr 14 UT 12:00-14:00 Observed by Osawa (Awajt-Shima,
Japan, 8" reflector, x288) "Photos in blue and orange taken. Ill-
defined obscur. in blue photo in S. part of crater compared with
orange. (neg. is so faint it is doubtful. Apollo 13 watch. Similar to
Alter's findings in Alphonsus)." NASA catalog weight=2 (low). NASA
catalog ID #1250.
SW of Pico 1844 Apr 25 UT 20:00? Observed by Schmidt (Athens,
Greece, ? refractor) "A bluish glimmering patch of light not
quite within the dark side" NASA catalog weight=4. NASA
catalog ID #123. ALPO/BAA weight=3.
On 1965 Jul 08 at 01:00?UT a white streak was seen in Grimaldi,
extended towards the limb. This was observed by Rubens de
Azevedo, et. al., Brazil. The Cameron 1978 catalog ID=884 and
weight=3. ALPO/BAA weight=2.
On 1990 May 03 at UT 02:03 D. Darling (Sun Praire, WI, USA, seeing
steady) observed a point of light inside Alphonsus just to the north
of the central peak, along the "center ridge". It was seen again, half
way between the central peak and the noth west rim - along the ridge.
All other features were normal. The Cameron 2006 catalog ID=403 and the
weight=3. The ALPO/BAA weight=3.
Alphonsus 1967 Aug 13 UT 18:40-18:55 Observed by Horowitz (Haifa,
Israel, 8" reflector?) "Glow or hazy patch seen while using filters.
Brighter than background. Not seen after 2055 or next nite" NASA
catalog weight=3 (average). NASA catalog ID #1041.
On 1972 Apr 21 at UT19:01 Mattingly (Apollo 16 commander, in orbit
around the Moon, using his naked eyes) saw a bright flash from below
his horizon on the lunar farside (approximate longitude=180 deg). he
was dark adapted at the time. However no sesimic event was recorded and
so Cameron suspects that this was not a meteor impact but a cosmic ray
striking his eye. The Cameron 1978 catalog ID=1331 and weight=3. The
ALPO/BAA weight=3.
Peirce A (Swift=IAU name) 1937 Mar? 23? UTC 22:00 Observed by Wilkins
(England, UK, 12.5" reflector) "Obscuration on floor if crater. Crater
invis. (similar to #394, 396)." NASA catalog weight=4 (high). NASA

On 1887 Nov 23 at 16:15-17:00 UT Von Speissen & others of Berlin,
Germany, using a 3.5" refractor (x180), saw a "Triangular patch of
light (time in Middlehurst catalog wrong? Moonrise was at > 18:30h. If

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
(Reading, UK) found a large dark spot on the south east floor. Other
observers: J and A.cook (Frimley, England) could not confirm but their
seeing was IV and tranparency was poor" Mobberley found no colour and
also no detail on the floor. BAA Lunar Section Report. Cameron 2006

Plato 1882 Mar 27 UTC 20:10-21:00 Observer: A.S. Williams (Brighton,
UK, 5.5" saw the shadow filled floor of Plato at Sunrise with a
"Glowing and curious milky kind of light". About 1 hour after sunrise
at Plato, there was no trace of this effect. The TLP filled the whole
floor except at a quarter of the diameter from the east wall which was
actually quite black. The observer saw a curious phosphorescent glimmer
at sunset (April11th?). Cameron comments that Birt, Nelson and Waugh
saw obsecuring mist or fog in Plato on many occasions. Cameron 1978
catalog ID=229 and weight=3. ALPO/BAA weight=3.
A track of reddish light, like a beam, was seen

On 1988 Jul 23 at UT03:07 D. Darling (Sun Praire, WI, USA, 12"
reflector, x150, seeing = 6/10) discovered that the dark area on the
floor of Proclus, seen earlier by UK observers was still present, but
less so (?) and the shape changed. When viewed through a green filter
it was less distinct. "Change with two other filters. Polarizer gave a
circular shape with a knot on SE side & W58 in White." The measured
brightness of Proclus was 9 on three sides and 8.5 on its west rim. The
floor was 5.5, but the dark spot was 4. Alphonsus, Bullialdus,

Plato 1976 Nov 30 UT 19:15 T. Flynn (Edinburgh, UK, 29cm
reflector, Wratten 25 and 44a filters) observed that there
were two whitish semi-circular tide like marks enclosing two
dark patches adjoining the interior west wall The observer was
puzzled because if these were two masses of spawning foot
hills, then why would the cental areas, presumably the higher
parts, be dark - when the contrary is usually the case?

very good at the time. NASA catalog ID #1039. NASA catalog
weight=3. ALPO.BAA weight=2.
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 see and
neighboring spots almost as bright made it difficult to distinguish
which one was Peirce A. ALPO/BAA weight=3.

good). Observer reports a bright spot, as bright as the
central peak in Aristarchus on the NW rim of Herodotus at
19:10 (still there at 19:15, but the curious thing was that it
was not visible earlier at 18:50? Now there is a bright
craterlet here, and the observer doubted if what he had seen
was unusual - though we have the rise in brightness o20
minutes to account for? The ALPO/BAA weight=1.
On 1971 Apr 09 at UT 22:30-23:05 N. Brown (Huntington, York, UK, 37cm

in the north east (IAU?) quadrant of the floor there was a very bright
pin-point blue-white flash of magntude 2 for approximately 0.5seconds.
After this the bright glowing of the crater diminished over about 15-
20 sec befofre returning to normal. The Cameron 1978 catalog ID=1366
and weight=3. The ALPO/BAA weight=3.
Plato 1919 Mar 05 UT 17:19:17:34 Observed by Selivanov, Tartakov
(Russia, 4" refractor? x150) "Crater seemed to be an intense green in
the background of Ashen light. Slightly to the left (east?) of it's
centre a bright spot that sparkled with a phosphor. light, lighting up
the whole crater so that its W. edge could be seen. Light did not
change for the whole time." NASA catalog weight=4 (good). NASA catalog

Watkins,et al in England - but this was later than the event)" NASA
catalog weight=2 (poor). NASA catalog ID #1325.
On 1939 Feb 23 at UT17:00 Malakhov, Filippoova (Russia) observed an
