Aristarchus 1950 Jun 29 UT 05:20-05:41 Observed by Bartlett
(Baltimore, MD, USA, 3.5" reflector x100, S=6, T=5) "Strong
bluish glare on E..SE wall." NASA catalog weight=4. NASA

(65E, 56N) near Endymion & Mare Humboldt 1968 Jun 10 UT 02:35 Observed
by Provenmire, Robinson et al. (Hamburg, PA, USA, 6" reflector x105,
Seeing=good, alt=20deg) "While waiting for reappearance of Antares from
a grazing occultation at 13+/-4deg P.A. saw a prolonged blue flash
lasting from minimum of 1/2 to a max. of 2.0 s. Several others along
obs. path of several miles also saw it so not a local phenom. (located
38 deg from cusp, azimuth=157 deg?)" NASA catalog weight=5 (very good).

On 1897 Jun 14 at UT 23:00 Pickering (Cambridge, Mass. USA) observed in
"Schroter's valley and the vicinity variations in vapor colum. Break in
col. toward F and eruption of crater D. 3.4 d after sunrise". The
Cameron 1978 catalog ID=389 and the weight=3. The ALPO/BAA weight=2.
Galvani B: On 2019 Sep 13 UT 23:26 K. Kilburn (Manchester, UK,
BAA - ED80 refractor, x2 Barlow, Canon 550 DSLR) took a
sequence of images from 23:25-23:27 UT. On one of the images,
taken at 23:26UT there is a blue/green spot on Galvani B.
There is a hint of a possible fade of the spot in the other
images but this is not conclussive. Te spot might just be a
cosmic ray event or a bright part of the crater rim coming
into view under brief exceptional seeing for one frame only.
We need simlar illumination, and if possible topocentric
libtation images, under different atmospheric conditions to
confirm this. It would be great if the images were in colour
too. The ALPO/BAA weight=1.
Plato 1980 Oct 23 UT 21:00(+/- approx 1 hour) Observed by
Chapman (Kingston Upon-Thames, UK, 11.5cm refractor, seeing III,

reflector) Taruntius faded from Vmag-3.21 to 4.04, a 0.82 difference in
magnitude in 2.5 hours - a photometric measurement. The average
magnitude for this age is 4.03, so therefore the crater had brightened

On 1981 Oct 15 at UT06:03-06:51 D. Louderback (South Bend, WA, USA, 3"
refractor, seeing=1-2 and transparency=5) observed that the brightenss
of 4 sun lit bright spots differed in red and blue light. "Appeared as
a cross. the 2 points A & D on his sketch (index) were affceted. They
were 10 pts dimmer in red than blue. Not due to seeing as they did not

Aristarchus 1970 Apr 23 UTC 07:00
Observed by Thomas
Aristarchus and vicinity 1975 Feb 28 UT 03:20-03:45 Observers LeCroy
Jr & Sr (Springfield, VA, USA). NASA catalog states: "Orange flash in
crater that then spread over whole crater then turned to bluish haze at
0320h. Couldn't see surface underneath. All W. hemisphere was brighter
than normal. Blue was only on Aris. Rest of Moon was examined for
phenom. but none seen elsewhere. Gone by 0343h (just a few hrs after

Plato 1966 Sep 02 UT 0625 Observed by Kelsey (Riverside, California,
USA, 8" reflector x300) "Landslip at west would not focus. (Ricker not
certain it was a real LTP)." NASA catalog weight=2 (low). NASA catalog
ID 973.
In 1950 Jul 02 UT07:22 Bartlett (Baltimore, MD, USA, 3.5"
reflector) saw no dark bands on the inside of Aristarchus,
despite detail being seen elsewhere. He would normally have
expected to have seen bands at this colongitude, based upon past
observations. The ALPO/BAA weight=2.
On 2002 Sep 23 at UT22:45-23:56 C. Brook (Plymouth, UK) noticed that
the bands inside Aristarchus varied (UT22:45-22:56) in definition
whilst the rim of Herodotus and the rays of Kepler and Copernicus
remained sharp. These bouts of variation were 1-2min in duration. At
23:56UT when he checked again the periodic blurrings of the bands were
still present. The observer suspected atmospheric effects. M.Cook
(Frimley, UK) observed 22:00-22:30 and could see only 2 bands on the
west wall - but this may have been because of poor transparancy. The
ALPO/BAA weight=1.
Aristarchus 1964 Oct 23 UTC 02:35-02:45 Observed by Bartlett
(Baltimore, MD, USA, 3" refractor, 133 & 200x, S=3-5, T=4) "South floor
region granulated, 6 deg bright with very faint trace of pale yellow
color; rest of crater 8 deg bright." NASA catalog weight=4 (good), NASA
catalog ID #859.
Aristarchus 1983 Oct 23 UT 19:00-01:30 Observer: Foley (Kent, UK,
12" reflector, seeing=II) noiced at 19:00UT an extended bright
spot on E wall and extending beyond. This was brighter than other
areas of the crater. There was also occasional star-like
glistening. Foley comments that the inside of Aristarchus was
slightly obscured. The TLP started fading from UT20:30 and
finished by 01:30UT. six out of nine independent observers
confirmed the effects seen. In total 14 observers observed, 9
reported back and 6 found abnormalities in Aristarcus though all
encountered variable seeing conditions - some had spurious
colour. Cameron comments that this was one of the best
recorded/confirmed TLP events. All CED brightness measurements
obtained were very high. Moore, Nicolson and Clarke (5" refractor
and 15" reflector, 230-350xseeing III) found the crater to be
very bright at 19:11UT through a 5" refractor and there was a
blob on the east rim (Bartlet's EWBS?) at 19:14UT. Nicolson also
saw a very bright star-like area on the eastern wall but this was
not defined as it usually is. The crater was also very bright at
22:43UT using the 15" reflector available to these observers. At
01:07UT they used a Moon blink and discovered that the bright
region was bright in blue light and less bright in red - although
this was not a detactable blink when switching rapidly between
filters. They found that the crater had returned to normal by
01:15UT. M.C. Cook (Frimley, UK, seeing III-IV) observed a large
diffuse spot on the east of the crater that was brighter in blue
than in red light and the CED device gave a high reading. J.D.
Cook (Frimley, UK, seeing III-IV) made a skecth that showed the
bright spot extended on the east wall - again the CED reading was
high and a lot of detail was visible on the floor. A.C. Cook
(Frimley, UK, seeing III-IV) also noted remarkable detail and the
bright (as confirmed by CED) blob on the eastern rim. G. North
(Sussex, UK, seeing III-II) also confirmed the bright blob on the
eastern wall. Wooller found the north west wall was a dirty
yellow colour - though no colour was seen elsewhere in or outside
the crater. Mosely found the crater to be bright and his sketch
revealed the extension of the bright blob on the eastern rim and
again a great deal of interior detail. Amery (Reading, UK, seeing
III) found Aristarchus to be "a brilliant splash against dulled
background in violet filter, especially polarizing filter. CED +
polarizer readings high, but not as high as previous night".
Mobberley (Suffolk, UK, seeing III-IV) remarked that "spurious
colour a total mess around Aristarchus & nothing abnormal seen".
A photograph was taken at 20:50UT reveals the bright blob and
entire detail. Peters (Kent, UK, seeingIII-II) observed
Aristarchus with a UV screen from 20:15-21:23UT and comented that
althogh being very bright, there was no variation between white
and UV. It was checked with a Moon Blink device and the radial
bands were clearly seen in white light, < in blue. The Cameron
2008 catalog ID=233 and the weight=5. The ALPO/BAA weight=4.
In 1962 Sep 16 at UT08:05 Spirad (Victoria, B.C., Canada, 48"

London, UK, seeing III, but worsening (but not as bad as IV)
towards the end of the observing period, transparency 100%
clear, 22cm Newtonian reflector, x144, x185). The floor seemed
quite devoid of detail, apart from a vague mottling seen during
the briefest moments of best seeing conditions. At the start of
the observing period he could just glimpse the central craterlet
at x185, but could not be sure. ALPO/BAA weight=1.
On 1994 Apr 03 at 11:23UT D. Darling (Sun Praire, WI, USA) noticed that

On 1981 Oct 21 at UT 11:35-11:48 B. Hobdell (St Petersberg, FL, USA,
10" reflector) found that the south peak of Plato on floor glowed white
at 11:35UT, then a milky shade spread all aorind Plato's floor
(previously completely shadow filled). The needle like shadows started
to be indistiguishable through the sunlight (dawn on Earth). The cloud
like feature was washed out by daylight at 11:48UT and conformed to the
"white area except a tail that reached the cetre of Plato" Spurious

On 1981 Oct 21 at UT13:40-13:45 D. Louderback (South Bend, WA, USA,
10" reflector) observed a cloud on the north east quadrant of
Aristarchus crater, and also covered the bright spot on the east wall
(Cameron says that the east wall bright spot is Bartlett's "EWBS".
Louderback mentions that this TLP gave Aristarchus a diamond ring

On 1973 Feb 23 before UT 23:00 P. Moore (Selsey, UK) reported
activity detected in Aristarchus. Fitton ovbserved from 23:40-
00:20 and obsrved nothing unusual except for a minute white
area, about 1 km in diameter about 2km north of the central
peak. This spot kept on coming and going in the seeing. Fitton
regarded this as a permanent spot, although he had never noticed
it before. Nor could Fitton see the colour that he had noticed
on the previous night. A BAA report. ALPO/BAA weight=1.

of Jupiter and also Jupiter's third satellite (the
diameter of the active part of the volcano was at least
twice the angular diameter of Jupiter's Moon). The shape
was an irregular round figure with very sharply defined edges.
It resembled a small piece of burning charcoal, when it is covered
by a thin coat of white ash. The other two volcanos were
much further towards the centre of the Moon and
resembled large faint nebulae that are gradually
much brighter in the middle; but with no well defined luminous
spot within them. These three spots are plainly to be
distinguished from the rest of the marks upon the Moon;
for the reflection of the Sun's rays from Earth is, in its present
situation, sufficiently bright with a ten-foot reflector, to
show the Moon's spots, even the darkest of them. Such
similar phenomena were not perceived in the previous month,
despite using the same telescope. The volcano was not as bright
as his 4th May 1783 sighting (resembling a 4th magnitude star as

On 1978 Jan 12 at 08:21UT (assuming this is not local time) V.A.
Golubev (Ussurian Sam Station, Vladivostock, Russia, x100) saw on the
western edge of the Moon an occultation of the magnitude 6? star
ZC2394. Just prior to the occultation, between the star and the dark
limb could be seen a bridge of light. The ALPO/BAA weight=1.
On 1980 Nov 10 at UT18:05 J-H Robinson (Teighmouth, Devon, UK, Seeing
III, Transparency poor, Filters Wratten 25 (red) and 44A(blue)) found
the area to be bright in red and dull in blue - but suspected that this
might have been a permanent colour blink e.g. natural colour. This does
not have an entry in the 2006 Cameron catalog. ALPO/BAA weight=1.
On 1980 Nov 10 UT 17:55-18:15 J-H Robinson (Teighmouth, Devon, UK)
observed the floor patches in Plato to be easy in red, but not so well
seen in blue. This is a BAA Lunar Section report. ALPO/BAA weight=1.

On 1990 Apr 28 at UT 01:19-01:25 F. Graham (Marshall TWP, OH, USA, 6"
reflector) during a failed attempt to observe the occultation of X6493
that was thwarted by clouds, noticed that Gassendi was "Gass,>>,>Aris
or anything else". The crater had a "milky lustre". It is possible that
another occultation observing group may have a video of the Earthshine
at this time. Darling (Sun prairem WI, USA, 20x50 binoculars) could not
see Earthsine, though the sky was bright at the time. The Cameron 2006
catalog ID=402 and the weight=0. The ALPO/BAA weight=1.
In 1824 May 01 at UT 21:00 Gobel (Koburg, Germany) observed near
Aristarchus, a blinking light of magnitude 9-10, in Earthshine. The
ALPO/BAA ID=99 and the weight=4. The ALPO/BAA weight=3.
Picard 2002 Sep 10 UT 02:30-03:21 Observed by Gray (Winnemucca, NV,
USA, 152mm refractor x248,S=2-3, T=5) "observed in White light and
through Wratten Red 25 and Blue #38A filters. The crater through the
Red 25 filter looked very similar to the view in White light. Using the
Blue 38A filter Picard almost dissapeared - it looked like a dim,
faintly observable black spot with the sunlit, east facing west crater
wall barely visible. Observer had not observed Picard very often, so
was not too familiar with it but it seemed odd that it almost vanished
through the blue filter." ALPO observational report. The ALPO/BAA

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.
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

On 1972 Apr 17 at UT 20:10-20:45 Hvidore (Denmark, 2.5" refractor, x58,
x100, seeing=good) noted a brightening of the dark limb between
Hercynian mountains and Cleostratus crater. Thought that it was due to
atmospheric disturbance. Cameron says similar to other reports e.g. No.
1156. The Cameron 1978 catalog ID=1330 and weight=1. The ALPO/BAA
weight=1.
In 1824 May 02 at UT 21:00-21:15 Gobel (Germany, seeing = excellent)
saw near Aristarchus (47W, 23N) a soft (matte) light like a star seen
through mist. Brightness increased suddenly to magnitude 9-10. After
several seconds it became weak, finally disappearing. repeated this 3
to 4 times in 15 minutes. The Moon was a very narrow sickle shape and a
major feature could be seen in Earthsine. The date given was 1821 but
Cameron says it is 1824. The Cameron 1978 catalog ID=88 and weight=4.
The ALPO/BAA weight=3.
On 1969 May 20 at UT 19:35-20:30 Gomez (Spain, 12" reflector) observed
blue-white pulsating light in Aristarchus that illuminated the inner
walls - it was maximum at 19:55UT. This observation was made during the
Apollo 10 watch. The Cameron 1978 catalog ID=1128 and weight=5. The
ALPO/BAA weight=2.
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.
In 1963 Oct 22 at UT 21:00? Andre (Belgium, 2.25" refractor) noticed
that Posidonius A's shadow was not seen when it should have been seen.

On 1975 Mar 18 at UT 00:57-04:00 Reiland, Brown and Lojeck (Pittsburgh,
Pennsylvania, 6" reflector x45 and 8" reflector x200, photos taken)
observed the following at Aristarchus: "While obs. Earthshine on moon,
saw it glowing -- a bright steady star-like glow, est. at 5-8th mag.
First noted at 0057h. Obs. other obj. then came back to it. It was

NASA catalog weight=5 (very good). NASA catalog ID #1164.
On 1969 May 21 at UT 20:00-21:00 Brandli and Germann (Switzerland, 6"
refractor) observed a slow orange-red blinking on the surrounding area
of Aristarchus. It was seen less markedly the next night. Wald (Zurich,
Switzerland) noted at 20:30UT that the crater was pink (Confirmation
says Cameron) - this was during the Apollo 10 watch. The cameron 1978
catalog ID=1131-1132 and weight=5. The ALPO/BAA weight=4.
Fracastorius 1973 Mar 09 UT ~19:57 Robinson (Devon, UK) saw a
Moon Blink (colour) in this crater. This crater is long
suspected of giving permanent blinks due to natural colour. The
ALPO/BAA weight=1.
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.

On 1969 May22 at UT2045-2105 Wald (Zurich, Switzerland) observed the
pinkish colour in Aristarchus was less marked tonight. The astronauts
were alerted and at 22:12 reported no activity but could see the crater
and Earthshine was strong near the terminator. Apollo 10 watch,
spacecraft far from the terminator. The Cameron 1978 catalog ID=1134

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.
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.
Mons Piton 2022 Aug 04 UT 19:41-20:10 T. Smith (Codnor, UK,
16inch Newtonian, x247, Seeing IV) mountain was very bright
and red around its eastern slopes. An examination of the
bright and contrasty Proclus crater revealed that to be
relatively colour free compared to Piton. An examination of
other features, north and south along the terminator revealed
some tinge of coloiur but not as strong as on Mon Piton. Mons
Piton examined with a yellow filter at 19:50 and still showed
red along the eastern side, other features along the
terminator had no colour through the filter. Video images by.
A.Cook (Newtown, UK) made earlier at 1929 & 19:40 UT, (in the
SWIR (1.5-1.7 microns) did not reveal Mons Pico as especially
bright - but resolutioin was poor. A friend of Smith, phoned
up the next day to say that they saw a mountain on the limb
exhibiting red on the 14th August. Probably the redness was
due to atmospheric spectral dispersion as the Moon was low,
and it was especially visble on Mons Piton as this is an
exceedingly contrasty object on the terminator. ALPO/BAA
weight=1.

On 1991 May 21 at UT05:30-06:15 J. Green (Orangevale, CA, USA, 11"
reflector) photgrapphed a broad bright band stretching east and north
of Cassini crater in 3 exposures taken 10 minutes apart. This
photographic sequence shows a gradual widening towards Cassini and by
the 3rd exposure the band is touching (and then obscuring) Cassini. A
"fan" was visible in the north east and WSW directions, later this was
seen as rays and this was even seen in the view finder of the camera.
Cameron comments that this might be lens flare but suspects that it
would not have been seen in the view finder. The Cameron 2006 catalog
ID=427 and the weight=5. The ALPO/BAA weight=2.
Hyginius Cleft 1966 Jul 25 UT 04:40 observed by Kelsey (Riverside, CA,
USA, 8" reflector, x300) "Points at opposite ends of cleft were very
brilliant in red Wratten 25 filter & very dull in blue Wratten 47
filter. Richer uncertain if real LTP." NASA catalog weight=1. 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
year =1887, age=8.8 days & time OK. must be same observation as ID=256
in Cameron 1978 catalog - note similarity of names and also the
reference date). Cameron 1978 catalog ID=258 and weight=1.
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
catalog ID #412. Note this is almost certainly supposed
to be 1934 Dec 23!
SE of Ross D 1964 Aug 16 UT 04:18-05:20 Observed by Harris and
Cross (Whittler, CA, USA, 19" reflector?) "Bright area.
Condensations varying with time" NASA catalog weight=3. NASA

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.
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.
A track of reddish light, like a beam, was seen
crossing the shadowed floor of Plato.This TLP has an ID
No. of 17 in Cameron's 1978 catalog and a weight
of 3. It has an ALPO/BAA weight of 2.
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.
On 1979 Dec 27 at UT 05:32 D. Louderback (South Bend, WA, USA, 6"
reflector x240, seeing=3-6/10 and T=4) noticed "2 small high-sun areas
nr. Eimmart - brightening around Mare Crisium, except for interior of
Proclus - in blue light. They were brighter than 2 spots on Cap.
Agarum rated 8.5 & Proc. 9. Not as bright next night. Probably a real
blue light brightening". Cameron 2006 catalog ID=79, location on Moon:

On 1965 Sep 03 UT03:00-05:00 D.Harris (Located near Whittier
College, Whittier, CA, USA, using a 10" f/8.2 Newtonian
reflector, x78 & x208, seeing 5-6, transparency 2-0) observed a
ridge obscured SSW of Ross D. No drawing was made, only a
written description. "Ridge not visible near crater; possible
white patch 1/3 Ross D diameter" The ridge is the wrinkle ridge
extending NNE from Ross D, a well established often visible
feature. Harris comments that this was not one of the better TLPs
seen near Ross D, and there were no independent observers,
neverless he was ceratin of this being a TLP, and it was
consistant with other activity seen near this crater between 1964
and 1970. Cameron 1978 catalog ID 891 and weight=3. ALPO/BAA
weight=2.

Theophilus 1978 Nov 08 UT 20:49-22:00 Observed by J.D. Cook
(Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV)
Orange discolouration seen on ESE crater floor. Moon blink
tried, but no blink detected. By 21:10 the effect had lessened,
but was still orange. By 21:50-21:58 the effect was smaller and
perhaps more on the SE of the floor. Colour confirmed by Foley.
Fitton may also have been observing. At 22:00 A.C. Cook observed
and commented that a darkish, perhaps brown-orange colour seen -
but suspected it was probably spurious colour - but by now the
seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of
several features, including Theophilus, had not noticed anything
unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect
a blink, but noticed intermittent darkining on the shaded area
on the E. floor, but seeing was now IV. The darkening was more
noticeable in blue than red light. BAA Lunar Section
observation. 2006 Cameron catalog ID #40 weight=3. ALPO/BAA
weight=1.
On 1972 Apr 22 at UT 18:58-00:28 Hopp (75mm refractor, 1200mm focal
length,transparency 4 out of 5 and seeing 4 out of 5, located at 52deg
30' N and 13deg 15'E) Censorinus brighter than normal relative to
Proclus. Published in Hilbrecht and Kuveler, Moon and Planets, 30
(1984) p53-61. ALPO/BAA weight=1.
Clavius 1915 Apr 23 UTC 20:00 Observed by Cook (England?) "Narrow
straight beam of light from crater A to B" NASA catalog weight=1 (very
poor). NASA catalog ID #352. ALPO/BAA weight=1.
On 2009 May 03/10 UT23:20-00:11 P. Abel (Leicester, UK, 20cm reflector,
x312, seeing III-IV) observed that the north east wall was slightly
brighter than would have been expected, slightly blurred (not seeing
related blurring) and had a strong orange-brown colour. No spurious
colour seen elsewhere. A change in eyepieces showed the same effect. No
luck in alerting other observers. A drawing was made at 23:20UT and
finished at 00:12UT. At 23:12UT part of the inner NW floor had a dull
brown colour, whereas before it was grey.By 00:11UT the colour effect
was fading and by 00:18 seeing condirions were too bad to continue. M.
Cook (Mundesley, UK, 9cm Questar telescope, x80, x130, seeing III,
transparency moderate to good) had observed Tycho earlier in the
evening at 22:15UT, but had seen no signs of colour. W. Leatherbarrow
(Sheffield, UK, 8cm scope, high cloud interuptions and bad seeing) had
taken monochrome images at UT 20:07 and 20:10, but these showed nothing
unusual, and he checked the crater visually at 00:00-00:30, but
detected no colour, although the Moon's low altitude contibuted to poor
seeing conditions and some spurious colour was seen. CCD images from M.
Collins (Palmerston North, New Zealand) taken at 00:46UT showed
nocolour apart from spurious colour on contrasty edges, in no way
reflecting what was seen early by P. Abel. The ALPO/BAA weight=2.
Observer made a drawing over a period of 30 minutes. Upon
examining drawing, and comparing with photos made under
similar illumination was struck by the abnormality of a
a small white blob in the north east corner of the shadowed
floor. There should be no raised topography between the wall
and the central peaks that could give rise to this. The making
of the sketch overlapped with an earlier drawing made by Rony
de Laet (Belgium) which did not show this blob. Subsequent attempts
to find sketches/images at very similar illumination angles have
failed to show the blob in the north east corner of the chadowed
floor. ALPO/BAA weight=3.
Birt 1955 Apr 15 UT 03:20-05:00 Observed by Capen (California
Seeing=Excellent) "Small craters between Birt & wall were invis. at
times under excellent seeing, while craterlets on w.side were
continually obs." NASA catalog weight=4 (high). NASA catalog ID #586.
On 1990 Apr 04 at UT 21:30-21:50 B. LeFranc (France?) reported
observing a white flame effect in Copernicus crater (sketch made) -
though Foley comments that the actual location was east of the crater.

On 1975 Mar 22 at UT22:10-22:25 T.Flynn (Edinburgh, UK, 30cm
Newtownian, x75) observed 3 large areas on the floor of Plato to be
delicately darker in the blue filter. There were of different darkness.
He did not regard these as TLP, but permanent blinks. This is a BAA
report. The ALPO/BAA weight=1.
On 1991 May 24 at UT 00:05-00:08 UT Romualdo Lourencon (Sao
Paulo, Brazil, 60mm refractor, seeing=III) detected a circular
cloud in Jansen B and H? (Gazateer report says F and K). "The
crater of the event 100km diam. compared to Copernicus, dark

Gassendi 1967 Jun 18 UT 21:10-22:30 Observed by Whippey
(Northalt, England, 6" reflector?) "Faint redness outside NE &
SE wall of crater." Moore (10" Armagh refractor, x360) was
observing too 22:10-22:40, with and without a Moon Blink but
detected no redness, however his observing conditions were not
very good at the time. NASA catalog ID #1039. NASA catalog

2004 Jul 28 UT 07:25-07:31 R. Dewitt (Transparancy very poor due
to forest fire pollution - Moon looks red, USA, location: Mill
Creek, WA) observed several pin point-like orange flashes of
light occur (2-5 sec duration each and static wrt the Moon's
surface) across the bright illuminated side of the Moon with the
naked eye. Other much fainter, almost instantaneous sparkles
were seen. The brightest flash seen was of 5 sec duration.
Switching to binoculars (15x45, another fainter one was seen
too. Binouculars were handed to wife, who also confirmed similar
flashes. The ALPO/BAA weight=2.

Gassendi 1967 Jun 18 UT 22:50-23:59 Observed by Whippey
(Northalt, England, 6" reflector?) "Faint redness outside NE &
SE wall of crater." Moore (10" Armagh refractor, x360) was
observing earlier 22:10-22:40, with and without a Moon Blink but
detected no redness, however his observing conditions were not
very good at the time. NASA catalog ID #1039. NASA catalog

Aristrachus 1966 Jul 29 UT 03:40 Observed by Simmons (Jacksonville, FL,
USA, 6" reflector x192, S=7, T=4-5) and Corralitos Observatory (Organ
Pass, NM, USA, 24" reflector + Moonblink) "Spot on S.wall vis. only in

(very low).
On 1938 Mar 13 at UT 04:00-06:00 Barker (Chestnut, England, UK) noted a
slight reddish colour in Plato. However Fox (Newark, UK, 6.5"
reflector, x240) saw none on the south east wall, but instead saw a
yellowish glow on the southern floor at the same time (confirmation?).
Appearently Fox saw the same effect on Apr 10, 11, and May 8-11, then
on June 8-10. The Cameron 2006 catalog ID=432 and the weight=5. The
ALPO/BAA weight=3.
On 1989 May 17 at UT Fabian (Chicago, IL, USA, 4" reflector, x35-x50
and 8" reflector) noted a pale blue colouration in the ridges situated
west of Aristarchus and north of Herodotus craters, in the vicinity of
the terminator (and on the night side). Aristarchus itself did not have
any colour. Īt was only area with such color though there were numerous
others of similar elevation and relation to term. The colour was seen
in a 4" Cassegrain telescope, but when an 8" reflector was used at
02:30UT, even with the same eyepieces. Cameron comments that maybe the
larger telescope spread the colour out? The sketch that Fabian
suplied, suggested to Cameron that the TLP was located at Herodotus,
and the ridge was part of Schroter's valley - Cobra Head. The Cameron
2006 catalog ID=364 and the weight=2. The ALPO/BAA weight=2.
Aristarchus 1972 Apr 25 UTC 19:15-19:20 Observer Ventzke (located at
48.67N, 12.00E) - diffuse brightening on inner N. wall, reddish. 60mm

Herodotus 1998 Dec 30 UT 18:50-19:10 observed by J.Knott
(Liverpool, UK 22cm Newtonian, x216, seeing II, transparency
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.
In 1950 Aug 25 at UT 10:55 T.Saheki (Osaka, Japan) observed a
stationary yellow-white flash on the Moon of duration 0.2 sec
and mag 6.5. Cameron suggests that this was a meteor. The
Cameron 1978 catalog ID=536 and weight=0. The ALPO/BAA weight=1.
Two small conical mountains, near last 4th May eruption,
close to the third one that he had seen before, but not
these two. They were not on any map.
SE of Langrenous 1947 Aug 28 UT 21:00? Observed by Baum
(Chester, England) A long mountain mass, on limb to the SE of
Langrenus crater, had a decidedly bluish cast. To the north, on
the limb, were several ordinary peaks appearing in profile and
some were sharp and pointed. NASA catalog ID=498. NASA catalog

Aristarchus 1963 Oct 30 UT 01:50-02:15 Observed by Greenacre and
Barr (Flagstaff, AZ, USA, 24" Clark Refractor) observed 2 ruby
red spots - one just to the SW of the cobra's Head and the other
on a highland area east of Vallis Schroteri. A pink colour
formed coverting the SW rim of Aristarchus. Effects present with
or without Yellow Wratten 15 filer. Similar effects checked for
elsewhere on other craters but not seen. So presumed not to have
been due to chromatic aberation or astmospheric dispersion.
Effecta not seen in 12" refractor, but this may have been a
resolution issue. The NASA catalog ID No. is #778. The NASA
catalog weight is 5 (highly reliable). ALPO/BAA weight=4.
In 1962 Dec 09 at UT 07:36 Wildey and Pohn (Mt Wilson, CA, USA, 60"
reflector) observed that Oceanus Procellarum was 1.13 magnitudes
brighter than normal. Observation at sunrise and is abnormal if area
measured was mare. If it were an east facing wall it would be normal.

On 1992 Feb 16 at UT 01:05-01:35 P. Moore (Selsey, UK, 12.5"
reflector, seeing=III) found the north rim area to be both very
bright and misty - though he did not think it to be a TLP but
wanted it to be recorded, just in case. The Cameron 2006 catalog
ID=440 and the weight=1. The ALPO/BAA weight=2.
Aristarchus-Herodotus 1970 Apr 18 UT 20:14 Observed by MacKenzie
(UK,2.5" refractor x45, seeing Antoniadi I) "Fairly strong blink

Torricelli B 2002 Oct 18 UTC 20:56-21:59 Observer: G.North (UK, 8"
reflector, x134, Seeing Antoniadi IV, Transparency good) - thought that
Torricelli B was perhaps a little brighter than expected, especially
when compared to Moltke and Censorinus based upon past recollection of
relative brightnesses at this colongitude). Slight bluish tint seen as
well. The ALPO/BAA weight=1.
Aristarchus and Cobra Head 1966 Jul 30 UT 06:35-07:29 Observers Ariola
and Cross (Whittier, CA, USA). NASA catalog states: "S. part of Cobra
Head nr. Herodotus was a red spot; also nr. Aris. & the fork of

On 1975 Feb 23 at UT 18:00-00:24 P.W. Foley (Kent, UK, 12 inch
reflector, seeing Good), noticed that Aristarchus was a slate-grey
tinged with blue, and abnormally bright, fading at UT 18:47, and
decreased activity at UT20:45 after a cloudy period. Blue was seen on
the northern wall at UT19:00, but at 19:10 no colour, but instead an
obscuration. All normal from UT 21:04-21:46 according to Foley. At
UT19:00 G. Amery (Reading, UK, 10 inch reflector) noted shadowy grey
near the shadow under the south wall, indistinct small area, no colour.
At UT 20:00 activity increased. Colour negative fr. 150-300x till 21:10
(Hunt, Cambridge, UK, 2.5" refractor, seeing Poor-Very good). Negative
fr. 20:20-21:00 in bad seeing, and very good seeing at 200x all
negative (colour blink filters). From 23:45-00:20UT (Fitton,
Lancashire, UK, 8" reflector). Turner of Sussex, UK with an 8"
reflector, observed as well. (confirm. of activity earlier & neg.
later). Cameron 1978 catalog ID=1397 and weight=5. ALPO/BAA weight=3.
Aristarchus 1963 Oct 30 UT 05:00-08:00 Observed by Greenacre and
Barr (Flagstaff, AZ, USA, 24" Clark Refractor) a violet or
purple-blue colour formed beyond the NW of Aristarchus. ALPO/BAA
weight=2. This followed an earlier observation that night of two
red spots and a pink glow.
On 1975 Apr 23 at UT 20:30 J-H Robinson (Teighmouth, Devon, UK, 260mm
reflector, x200). Observer was observing since 20:30UT, at 21:00UT
though they noticed red on the outside south wall of Aristarchus, a
hazy ill defined area that was larger in a red filter than in blue
filter, and outside east wall was bright in red. At 21:08UT the outside
west wall of Aristarchus no longer gave a colour blink reaction, and at
21:22UT the colour blink on the southern end of the crater ceased, but
the image blur remained (in both red and blue filters) despite the rest
of the crater being sharp in detail. Observations ceased at UT 21:35
because the blurring at the southern end seemed to be normal and this
was confirmed when checked with photographic atlases. Other craters
such as Proclus, Pickering, Tycho, Gassendi, Copernicus, Alphonsus,
Plato, Menelaus, Manilius, Linne and Theophilus, showed no colour blink
reactions. However Picard had a red bright blink from 20:30-20:40 and
the permanant blink on the N. Floor of Fracastorius was detectable.
Also Plato floor shadings were clearer in red than in blue -
intermittently. This is a BAA lunar section observation. No estimation
of transparency or seeing is given, nor any comment on whether spurious
colour was seen in any craters visually. ALPO/BAA weight=1.
In 1959 Nov (Day unknown) at UT 21:15-22:15 Bradford (South Shields,
UK, 15" reflector, x480) observed in Littrow: "Cocealed by a dusky cloud.

On 1983 Oct 19 at UT 21:09-23:40 G. North (Bexhill on Sea, UK, seeing
III) found Aristarchus crater to be slightly blue in colour, and very
bright, despite the fact that no colour was seen elsewhere on the Moon.
At 22:08UT Foley (Kent, UK, 12"reflector, seeing II) obtained an
extremely high CED brightness measurement and also picked up a "blue-
violet" cast, especially inside the west rim, furthermore he saw noe

Aristarchus 1963 Oct 30 UTC 22:00? Scarfe (Cambridge, UK)
observed a 30% enhancement at 540nm in the spectra of
Aristarchus. The Cameron 1978 catalog ID No. is 778 and weight
is 5. The ALPO/BAA weight=1 because Oct 30 is not mentioned in
Cameron's refernce.

On 1983 Aug 22 at UT 05:44-06:33 D. Louderback (South Bend, WA, USA,
3"refractor, x150) found the brightness of Aristarchus (diffuse white
patch) to be 7 to 7.5 but apparently it is normally 8-8.5, so fainter
than normal. Another brightness reading found "brightening then nearly
extinction at S. wall similar to changes seen on Eimmart before.
Watched fluctuation compared to Cobra Head, they were similar but more
pronounced at Aristarchus" especially in blue light compared to red
(although there was a little brightness in red). Timings of these
fluctuations were 7sec, 7sec, 9-10sec and 9-10sec. The latter two might
have been seeing related as the crater enlarged up at these times. The
observer felt that the Cobra Head appeared fainter than the previous
year and had faded during the second set of brightness measurements.

On 1976 Feb 14 at UT23:35-0053 LeCroy (Springfield, VA, USA, 4.5"
reflector, x75, S=6 and T=4.5). A blue haze was seen on the east side
of Aristarchus and red haze on the west side. At 00:00UT details were
more clear and at 00:24UT Aristarchus and Herodotus, were seperated. At
00:34UT colours were gone. At 00:35UT blue was on Aristarchus and the
area was bright, but was black in a red filter. At 00:53UT the features
were clear and the colour gone and the brightness had decreased to 9.
Cameron comments that the colour was not due to temp. inversion because
of being dark in the red filter, implying a medium). The Cameron 1978
catalog TLP ID is 1428 and the weight=1. This is an ALPO report. The
ALPO/BAA weight=1.

On 1996 Dec 24/25 at 18:12-00:02UT P. Moore (Selsey, UK, using a 15"
reflector x250-360, and seeing III) saw a strong orange colour on the
south wall and floor of Aristarchus. He suspected it to be spurious
colour but could not detect colours on any other craters. The colour
remained but at 18:12 UT he suspected a trace on colour on Mons Pico
but was not sure. However he reported it to the TLP coordinator of the
BAA Lunar Section. The orange in Aristarchus gradually faded and had
almost vanished by 00:20UT when seeing was too bad to continue
observing. At 02:30UT he was able to re-observe again and there was
still a very very slight hint of orange in Aristarchus - but he
comments that if he had not been looking for it he might not have
noticed. ALPO/BAA weight=2.
Plato 1966 Aug 01 UT 06:14 Observed by Kelsey (Riverside, CA,

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
