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

a lot of spurious colour in the area. The Cameron 1978 catalog ID=111
and weight=0. The ALPO/BAA weight=1.
2004 Aug 31 UT 22:30-22:35 C. Brook (Plymouth, UK) looked at Gassendi
and noted a slight chestnut brown colouration in the dark area on the
crater floor to the north of the central mountain leading to Gassendi
A. It lasted for about two minutes during 22-30 hrs UT to about 22-35
hrs UT (observer unable be more precise). Used 60mm OG x120. Seeing
quite steady trans good. Checked Gassendi again at 23hrs UT to 23-05.
No sign of colour. Also area mentioned earlier seemed lighter now. No

On 1956 Dec 19 at UT 00:00? an unknown observer apparently saw a TLP
somewhere on the Moon. Cameron gives the reference for this as an
unnamed AGU meeting. The Cameron 1978 catalog ID=659 and weight=0. The
ALPO/BAA weight=1.
Mare Crisium 1973 Mar 20 UT ~19:55 Robinson (Devon, UK) patches
clearer in a red filter than in a blue filter. This is
unlikely to be a TLP, more likley something to do with effects
in our atmosphere, but is worth checking out, just in case.
ALPO/BAA weight=1.
Aristarchus 1978 Nov 16 UTC 19:40-19:45. Observer: Mark Kidger (UK, 6"
refractor x40, x133, x200, seeing poor-boiling) - saw the north wall of
Aristarchus to be an electric blue. No spurious colour was seen in
other craters (despite the conditions). No other observers were able to
confirm this due to the weather. ALPO/BAA weight=2.
On 1975 Dec ?? at 19:00UT P.W.Foley (Kent, UK), and possibly P. Moore?
(Selsey, UK) - unusual events were reported which might have been due
to minor structral changes. Albedo=76% (=7.6?). Cameron 1978 catalog
ID=1425 and weight=3. ALPO/BAA weight=1.
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.
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.
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.
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.
In 1962 Sep 16 at UT08:05 Spirad (Victoria, B.C., Canada, 48"

refractor, x128 & x160, Seeing III, transparancy average)
suspected on the eastern edge of Geminus, on the border of the
crater filled shadow and the eastern illuminated rim, a
brownish, almost speia hue. This extended for a short distance
from the floor shadow into the illuminated rim width and spanned
from the north to the south of the crater. For a comparison,
Cleomedes was checked but nothing unusual was noticed in its
shadow. The observer notes that Elger also saw a warm brown or
sepia tone. ALPO/BAA weight=1.

Aristarchus 1987 June 14 UT 04:43-08:00 Observed by Curtis, Jacobs, and
Manske (Yanna Research Station, Carl A. Fosmark Jr. Memorial
Observatory, Madison Astronomical Society, WI, USA, 17" f4.5 Dobsonian
and the 8" f10 SCT Celestron) "On the night 13/14 June 11:42 P.M. to
3:00 A.M. local time or 14 June 04:43 to 8:00 UT. Three people
witnessed this event and all three of them observed with three
different telescopes to rule out instrumental aberration. These three
pople were members of the Madison Astronomical. The three observers
involved are Keith Curtis, Tom Jacobs and Robert Manske. Keith Curtis
took detailed notes of the event as he observed it. The observations
were made at the Yanna Research Station, Carl A. Fosmark Jr.
Memorial Observatory of the Madison Astronomical Society following the
annual picnic. This is MAS dark sky site and is located near Brooklyn,
Wisconsin. As they were observing the night sky they saw the Moon
rising and noted a strong orange color due to atmospheric effects.
Approximately 1/2 hour after the Moon rise they decided to turn one of
the telescopes on it. It was at 04:43 UT, it was noted by Keith Curtis
that as the Moon rose it began to loose the horizon color effect and
return to its normal color, but he found that the red color was not
leaving the crater Aristarchus. At first they all thought this was an
atmospheric effect but decided it was a real event since they detected
a second crater (Euler) showing red color on its rim. Keith Curtis
said that the red color was very strong on the Western rim of
Aristarchus with a strong blue/green or aqua green on the Eastern rim.
Keith also reported that the glow opaque enough to prevent viewing of
the interior of crater Aristarchus. He said they observed until 3:00
A.M. daylight saving time or 8:00 UT. and the red glow was still
visible when they ended their observing session. Robert Manske
description of the event was that he saw two craters glowing a strong
red and blue giving it a rainbow effect. He said that the red glow was
so strong he was unable to see the craters underneath during the entire
observing session. Concerning the orientation of the red and blue was
on the crater he stated that he did not remember since he failed to
take any notes. Concerning whether there was any difference in
appearance when they observed it with the 17" f4.5 Dobsonian and the
8" f10 SCT Celestron. He said that he could not detect any difference
to the lunar formation or the color on it regardless of which telescope
he used. He did mention that as the Moon was rising it had the
appearance of one large Maria in the center of the disk. This illusion
disappeared as the Moon rose higher into the sky. When talking to Tom
Jacobs he said that he remembered that he did not see anything on the
Moon until 1/2 hour after Moon rise. He said that he remembered that
the entire Aristarchus region had a strong reddish or pinkish color.
All three witness all reported variations in the type of color they
were seeing. This would indicate that individuals color perception is a
major factor during a color event. Keith Curtis saw a very strong
coloration around the rim of the craters, where Robert Manske saw the
entire region covered by this red and blue coloration and he could not
see the interior of the craters underneath. Tom Jacobs reported that
the glow covered the entire crater but he could see the crater
underneath it. The Moon never achieved a height greater than 21 degrees
so it could be that what the observers saw was caused by the Earths
atmosphere. Further details can be found on the following web site:

with Wratten 25a and 38a blue filters. His report goes as follows:
Moon Blink carried out. In Red 25 Proclus looked nearly the
same as in white light. Through the Blue 38a filter, however, only the
brilliant lit south east wall was clearly visible. The northeast wall
was very dim with this filter. With no filters the NE and SE wall were
brilliantly lit, the SE wall was almost as bright as Aristarchus. A
thread like strip along the NW wall, possibly the rim of the crater,
was also brilliantly illuminated. The interior of the crater was a
featureless stygian black with the exception of a brilliant (intensity
9) thread of light that ran parallel to the illuminated east wall.
Whether this was an L.T.P. or an optical effect of atmospheric
turbulence is unknown, did not see anything similar elsewhere along the

On 1982 Aug 11 at UT03:30-04:15 Mobberley (Suffolk, UK) obtained a
photograph and made a sketch that revealed a needle-like shadow from
the west wall to near by the central craterlet - the latter was quite
clearly visible. What were not visible were the other four craterlets.

Tycho 1983Aug30 UT 00:15-00:18 R. Moseley (Coventry, UK, 6"
f/10 reflector, x60, transparency very good, seeing III,
improving with altitude) attention initially caught by the
impression of a rosy colouration along the NW crest and outer
wall. For perhaps 2-3 min this persisted - before fading
entirely. The observer felt that the cause may have been
psysiological - or short-lived spurious colour. However
interestingly nearby craters did not show the effect. A
sketch was made over a longer time span 00:15-00:40UT.

On 1981 Sep 20 at UT 08:00-09:40 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x342, seeing=excellent) detected the small crater on
its western rim But not on the eastern floor. This was odd because both
are equal in size, furthermore smaller craters could be seen and the
Moon was at a high altitude above the horizon, so seeing not a problem.

Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK,
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 1982 Nov 11 at UT 17:00-17:30 E.V. Arsyukhin (Moscow, Russia, 3"
reflector) saw three stationary dark spots suddenly appear in Mare
Crisium. There was one on the north and the other two in the south west
to south. They lasted approximately 30 minutes and then promptly
vanished. Cameron says that it cannot be this date because the Moon was

Reiner 1986 Jun 04 UT 09:15-09:33 Observed by Darling (Sun Praire, WI,
USA, 12.5" Newtonian x79, x40, x35, Seeing 6, sky clear and steady -
Moon 9deg above horizon). David Darling was out on the morning of 4
June observing the planet Mars. While studying Mars the crescent Moon
rose giving me a splendid view of the earthshine portion of the disk.
As the Moon rose higher into the sky he decided to turn the telescope
onto it to the earthshine region of the Moon. He made it a practice
to examine this region of the Moon to monitor for craters that appear
to glow under this light. While observing he became aware of a black
spot located in the sunlit portion of the Moon about 60 miles west of
the sunset terminator. At first he thought the black spot was a shadow
being cast by a large mountain or crater. When looking at his lunar
charts he could not locate any feature that would account for it. As he
continued to study the black spot he realized that it appeared darker
than any shadows on the Moon. It was at 4 June 1986 4:15 A.M. CDT or
9:15 U.T. when he first sighted the phenomena and it was at 4:25 A.M.
CDT or 9:25 U.T. that he realized he was seeing a lunar transient
phenomena event. It was at this time that he could start to see silvery
filaments or streaks in the black patch. Between 9:23 and 9:25 U.T. he
watched the black patch disappear. When the black spot had disappeared
he found that the location of the black spot was over the crater
Reiner. he estimated that during the L.T.P. event that area covered by
the black cloud was approximately 40 to 50 square miles. He also had
examined other formations on the Moon during this event and none were
exhibiting the same phenomena witnessed over the crater Reiner.
On 1988 Apr 19 at UT 01:15-04:00 J. Horne (Steadman, NC, USA, 8"
reflector, S=4/10) took photographs of the Moon's Earthshine (appeared
in the Aug 1988 Sky and telescope magazine). Aristarchus was bright. In
addition several members of the Madison Astronomical Society also found
the crater to be bright and one of them saw streaks and flashes from
the crater. Manske (8" reflector, x97, + binoculars, S=E) found the
crater to be "abnornormally bright" where as other craters in
Earthshine were just normal. Fryback's (Madison, WI, USA, 8" reflector,

of Aristarchus for 3-7 seconds of about 1 magnitude over the
background. From orbit at UT 18:46 the Apollo 11 crew Armstrong,
Aldrin, and Collins (in orbit around the Moon and using the naked eye)
were asked to take a look at Aristarchus after Earth-based reports of
TLP activity. Armstrong reported (after the solar corona had set, on
the night side) that probably Aristarchus "to be considerably more
illuminated than the surrounding area. It just has - seem to have, a
slight amount of flourescence to it". Collins reported a moment later:
"Looking out on the same area now. Well at least there is one wall of
the crater that seems to be more illuminated than the others. I am not
sure that I am actually identifying any phosporesecence, but that
definitely is lighter than anything else in the neighborhood". Houston
then asked if the crew could detect any colour and if the inner wall
was the inner or outer part? Aldrim commnted that it was the inner
wall and Collins mentioned thatno colour was incolved. The Cameron 1978

On 1975 Dec 08 at UT18:00-20:40 P.W. Foley (Wilmington, Kent,
UK, 12" reflector, x60-x624, seeing II, slight mist) found
Aristarchus to be less well visible than features such as:
Grimaldi, Reiner, Darwin/Byrgius, Kepler, Plato and Sinus
Iridum. Earthshine was exceptionally good tonight and was
orange/red in colour. Photographs were taken and these confirmed
the apparent dullness of Aristarchus. ALPO/BAA weight=2.
Grimaldi 1969 Jul 19 UT 20:39-20:45 Delaye (France, 25cm
refractor) saw a bright bluish spot near Grimaldi. 20:43 a
flash was seen by Thinon. Delaye saw flashes at 20:44 and
20:45. Between 21:00 and 23:00 (J. M. L.) da Silva (Rio de
Janeiro, Brazil, 19.5" refractor) saw a bright spot on the W

Grimaldi, so this maybe normal. NASA ID = 1167. The ALPO/BAA
weight=2.
On 1990 Mar 31 at UT 21:30 L. Jackson (England, UK?) observed a red
glow in Earthshine in Gassendi as shown in a sketch. Apparently
Gassendi can often show up red colours (according to Cameron) but
rarely is this seen in Earthshine. Foley saw the sketch and suspects
that the location was Gassendi. The Cameron 1978 catalog ID=397 and
weight=2. The ALPO/BAA weight=3.

(Marseilles, France, 10" refractor, x60) saw between 19:55-20:04UT
Aristarchus to be bright and in it pulsations with 10 sec duration. At
20:05UT it's spot brightened, at 20:08:50-20:35:50UT brightening and
pulsations of variable duration. At 20:55:50UT just a feeble flash.

On 1970 Apr 12 at UT 22:10-22:40 Censorinus was observed by Jean
Nicolini (Sao Paulo, Brazil, 12" reflector, x680). The crater
had a visible reddish hue--gap in bright area on western slope.
Colourless to pink to reddish. Environs also involved.
Photographs were taken. (Apollo 13 watch). Cameron 1978 catalog

On 1969 Jul 20 at 22:50-23:15UT Jean Nicolini (Sao Paulo,
Brazil, 12" reflector x430, S=II.5-III.5) saw a weak reddish
area on the north west(east?) wall of Eudoxus crater. An
English Moon Blink device showed it dark in blue and opaque in
red. Reddening remained unchanged while comparing it to
adjacent region and Aristotles. Colour index was toward dirty
orange. Colour most apparent in the good moments of seeing and
disappeared in the poorer moments of seeing, Cameron says that
this is opposite to what was expected if the effect was
atmospheric in origin and no colour was seen in Aristotles.

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 1975 Apr 19 UT 21:09 P. Foley (Kent, UK), detected blue in
Plato on east. Fiton at UT20:45 found blue along the south wall
at the east (IAU?) end, which was very bright white. Blueness
extended towards the large landslip at the east of the formation.
Immediately north of the landslip, where the bright wall curves
first westwards, then again northwards, red could be faintly
detected, folloowed by a very faint blue. All other parts of the
formation were normal. Examination with a Moon blink device
revealed no colour blink. J-H Robinson also found blue, with red
on the west wall (exterior?). By 21:30UT Fitton found Plato to be
normal and so was Proclus, though he did find Epigenes (bright
cresecent of east wall only) slightly blue to the N.W and red
to the S.E. Mare Crisium was normal. Prominent spurious colour
seen on Venus, but it was low in the sky, with blue to the north

On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector,
seeing II-III) noted that the south wall of Plato at the 11 o'clock
position, at the location of a cleft, was fuzzy on either side of the
cleft. There was also a deep red colour along the cleft and the outside
wall. The colour had gone by 22:40 though. All other parts of the rim
of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III)
sketched some obscurations at 22:03UT. At 22:08UT the red colour
reduced to a red line and vanished by 22:37. The south wall obscuration
varied in size and there was a possible obscuration at the 7 o'clock
position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and
M.Cook's observations. Detail inside the crater was sharp, but colour
oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km
away had atmospheric ripples affecting his observations. At 21:36UT G.
North described the south wall as odd in appearance and the terrain
south of this was lacking in detail - this was odd because elsewhere
Plato was nice and sharp. At 21:45UT though the north section of the

On 2013 Apr 22 UT 01:39-02:37 P. Zeller (Indianapollis, USA,
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=1.
On 1981 Aug 11 at UT21:05-21:36 G. North (England, seeing=poor)
detected, in green light, a darkening on the floor of Plato. This
effect was not seen elsewhere. J-H Robinson (Teighmouth, Devon, UK)
detected on the SSE rim (inner and beyond) a triangle that appeared
hazy in a wide range of filters at 21:05UT. However at 21:36UT it was
only hazy in green and blue light. No similar effect was seen
elsewhere. The Cameron 2006 catalog ID=150 and weight=5. The ALPO/BAA

Aristarchus 1989 Jul 15 UT 02:00-04:20 Observed by Manske, Weier,
Curtis, Keyes, Yanna, Norman, Knutson, Sullivan, Eichman and Radi (Carl
Fosmark Jr. Memorial Observatory, Madison, WI, USA, SCT C11) "Manske
initially observed a reddish tinge on the SE rim of Aristarchus. The
colour was present in different eyepieces. Two other pinkish tinge

On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector,
x300) using an English Moonblink device found colour on the south west
part of the floor. Note that for the times given by Cameron, the Moon
was below the horizon from California - so possibly these are local
times and these times need to be correctly converted into UT? The
Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.
On 1992 May 13 at UT 20:16-21:29 several observers reported a TLP in
Plato mostly concerning the visibility of floor craterlets, however
observer seeing varied from III-V. North (UK, 18.25" reflector)
reported "Colouration and floor craterlets very prominent. Seeing
Antoniadi V, Transparancy Poor.". Foley (Kent, UK, 12" reflector
seeing=III-IV) found the floor to be bright and in the better moment of
seeing detected floor craterlets. The WNW spot was misty some of the
time. Moore (Selsey, UK, 15" reflector, seeing V) had very poor seing
conditions. J.D. Cook and M.C. Cook (Frimley, UK, 3.6" reflector,
seeing II-III) used a CCD camera at 22:11 UT. The Cameron 2006 catalog
ID=445 and the weight=5. The ALPO/BAA weight=2.
On 1980 Dec 18 at UT20:46-23:58 A.C. Cook (Frimley, UK, 12" reflector,
40-250x, S=IV and transparency good) found the north west wall to be
brighter in red than in blue light, however the effect faded during
21:29-21:41UT and was gone by 22:40UT. There was however spurious
colour on the north west wall. M. Cook (Frimley, UK) found the central
peak to be both bright and diffuse, and brighter in red than in blue
light during 20:52-20:57UT, however at "22:53-23:58 c.p. very bright &
previous area decreased in size. No detail in white or red, just
visible in blue. Sketch (J. Cook) Orange out on NW rim & on NW side of

very bright. Cameron 2006 catalog TLP ID=120 and weight=5. ALPO/BAA
weight=2.
On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector,
seeing=III) found the region around the cleft on the souther rim to be
out of focus - however atmospheric conditions were turbulent until
23:18UT. An unsual dark triangular region (long base against rim) was
seen to extend from the inner rim at 12 o'clock onto the floor for 13-
16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK)
found the south east to soth west to be obscured again, but not as
badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the
dark region had 2 white bands on the side and the south west wall was
blurred like it was on the 20th July - this time tough colour was not
present. There were also two light patches on the floor. Mosely
(Coventry, UK) observed the south wall at x120 and found the wall out
of focus at the 11 o'clock location. Through a yellow filter he saw a
"white mistiness: on the top of the southern rim and only the south
east cleft could be seen (no colour). By 22:40-23:00 the effect had
cleared up. No dark triangular patch was seen. When Marshall (Surrey,
UK) observed (22:30-03:00) nothing unsual was seen, though a sketch
provided shows a light patch on the floor located at 11 o'clock. All
observations, made by all observers had some atmospheric turbulence,
however trsnparency was good. The Cameron 2006 catalog ID=225 and the
weight=5. The ALPO/BAA weight=3.

On 1963 Nov 28 at UT 00:30-01:45 Barr, Greenacre, Hall and
Dungan (Flagstaff, AZ, USA, 24" refractor, and 69" reflector)
observed pink on the outer SW rim and a red spot towards the S of
this. A red spot was seen on the eastern side of Vallis Schroteri
but only by Barr and Dungan. Other features checked for
atmospheric spectral dispersion and chromatic aberation - but the
colours in Aristarchus were not due to these. Smaller 12" scope
checked but no effects seen - presumably due to resolution and
image contrast issues? Pink on the SW rim may have been seen in a
69" scope by Boyce and Ford. ALPO/BAA weight=4.
Herodotus 1966 Jun 30 UTC 03:10-03:35 Observed by Bartlett (Baltimore,
MD, USA) described in the NASA catalog as: "Bright pseudo-peak again

lunations in '66" 4" x280 refractor used. NASA catalog weight=4 (high).
NASA catalog TLP ID No. #950. ALPO/BAA weight=3.
Herodotus 1950 Jun 27 UTC 02:30 Bartlett (Baltimore, MD, USA) reported
a bright point in crater. This is mentioned in the Middlehurst TLP
catalog but not in the Cameron catalog. The source comes from a
Strolling Astronomer article. ALPO/BAA weight=3.
On 1980 Aug 22 at UT20:15-21:29 J-H Robinson () detected violet on the
west wall of Aristarchus. Cameron 2006 catalog ID=105 and weight=5.

On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK,
12" reflector, x200, seeing=II) noticed in the area south east of
Manilius that it was brighter in red light than in blue light at
20:15UT whereas 1 minute later it was the same brightness in each
filter. The effect reappeared at 20:21UT and was particularly strong at
20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was
of high reflectivity in white light and was bright in red at 21:15UT,
thougjh the south east area stopped giving a colour reaction at
21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT
however at 23:55UT it was surrounded by a transient white ring that
varied in visibility in an irregular way. Foley found Manilius B had a
vivid blue interior and in blue light the ring was black. and not at
all seen in red or white light. The CED brightness measurement varied
from 1.9 to 2.4. All other regions observed were normal in brightness.
Violet was seen on the west wall of Aristarchus though. M.Price
(Camberley, UK) found a possible blink in Manilius B but was observing
under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5.
ALPO/BAA weight=4.
On 1992 Mar 16 at UT 00:39-01:14 D. Weier (Sun Praire, WI, USA, 11"
reflector) at 00:39UT noted some soft, diffused, faint ïllumination
within the shadow projected over the Cobra Head area, though it had a
sharp appearance to the edge of the shadow. D. Darling (Sun Praire, WI,
USA, 11" reflector) was taking photographs from UT 00:51 and making
drawings and visual descriptions. The first 3 photographs in the
sequence have the crater as normal. Four other photographs reveal an
abnormality. Seeing conditions were excellent and a great deal of
surface detail was seen inside Aristarchus crater - however the
apeparance of the Cobra's Head was "washed out" and again shadows near
to this were illuminated. The NASA catalog ID=442 and the weight=5. The
ALPO/BAA weight=3.
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.
The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
In 1962 Dec 09 at UT 07:42 Wildey and Pohn (Mt Wilson, CA, USA, 60"
reflector) observed that Aristarchus was 0.80 magnitudes (x2) fainter
than average for this age (photometric measurement) Vmag=3.80, average=
3.0. The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
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
in a spot 1/2 way between the 2 craters. Drawing (Apollo 13
watch). NASA catalog weight=2. NASA catalog ID #1257. ALPO/BAA
weight=2.
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.
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.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi
III seeing, 12.5" reflector) "Intensely bright craterlet south of central
peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed
the crater was highly luminous at 21:20, and surrounded by a blue halo that
had a darker blue band within it. This craterlet faded over time, and by 21:20
Moore considered that it was no longer prominent, by 21:22 Foley confirmed the
reduced brilliance, and by 21:30 Moore considered it to be perfectly normal.
Moore considers the nimbus effect to be normal. The Cameron 2006 catalog ID=

On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar
telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a
dusky dark gray area just north of Herodotus and just south of the
Cobra Head. The interior shadow on the east of Herodotus by comparison
wad black and distinct. No change was seen when viewed through a
rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA)
was observing at the same time but had better observing conditions and
could see detail in this region, suggesting that it was not a TLP.

Aristarchus 1996 Oct 25 UTC 19:05-19:55 Observed by Livesey (Scotland,
65mm reflector x88) "red colour seen along E/SE rim and along S.edge of
SW ray - colouration not visible on other craters. Observations
terminated by hazy cloud drifting over Moon. Observer remarked that it
looked like chromatic aberation, but telescope was a reflector and no
colour was seen elswehere on the Moon. Cook (Frimley, Surrey, UK)
19:48-19:55 noted red on E. rim exterior and on SE part of central
peak, and blue on N. rim - strongly suspected spurious colour".

1964 Jul 23 UTC 04:45-06:07 Observed by Bartlett (Baltimore, MD, USA,
5" reflector, x180, S=1-4, T=3) "S.region of floor was granulated &
rated 6deg bright, rest of crater 8deg. Floor there was distinctly
yellow-brown. Had never seen browns or yellows before June 25, 1964.

Bullialdus 1979 Oct 04 UT 20:24-21:25 JH-Robinson (Devon, UK,
260mm Newt. x200 Seeing Antoniadi IV-V, Transp.=haze) observed a two
bright points on the south west floor patch to be brighter in red than
in blue at 21:12. The effect was still present at 20:36 but back to
normal by 20:43-20:48. Amery (Reading, UK) found a possible brownish
tinge on the west wall, though spuroius colour was present elsewhere on
the Moon. Foley found the WSW corner darkened in blue light. Cook found
pink on south rim of Bullialdus and Pedler found Bullialdus to be a
confused mass with bright and dusky spots and patches - no colour seen.
Cameron 2006 catalog ID=72 and weight=0. ALPO/BAA weight=1.
On 1979 Oct 04 at UT21:05-23:40 P.W. Foley (Kent, UK, 12" reflector,
x360, seeing=II) detected colour in Aristarchus (and also in Bullialdus
- there was a TLP alert at this time for Bullialdus) but nowehere else
on the Moon. Aristarchus had a CED brightness value of 3.8 at 21:05
(though at this time no colour) and 3.4 at 23:40 and the floor was now
slate blue/gray in colour. Other features remained constant in
brightness. The Cameron 2006 catalog ID=72 and the weight=0. The
ALPO/BAA weight=1.
Near Aristarchus 1788 Apr 19 UT 20:00? Observed by Schroter
(Lilienthal, Germany) Event described as: "Small area very
brilliant & other bright spots". No additional references
given. NASA Catalog Event #44, NASA Weight=4. ALPO/BAA
weight=1.
Plato 1788 Dec 11 UT 22:00. Bright point seen on the dark part
by observers in Mannheim. Cameron 1978 catalog ID is 38 and
the weight assigned is 5. ALPO/BAA weight=1.
On 1988 Apr 01 atUT01:15-03:20 H.Hill (Lancaster, UK, 10" reflector,
x286) observed that east of Lichtenberg were ëxtensive rosy areas"
around the northern edge of the lava sheet. Hill believes that it may
have been the same effect as seen by Madler (Germany), Barcroft (USA)
and Baum's (UK) 1951 observation. The colour was "ünmistakable" and
nothing to do with the atmospheric spurious colour. Other features were
checked. the cameron 2006 catalog ID=322 and the weight=3. THe ALPO/BAA
weight=2.
On 1977 Apr 02 at UT22:00-00:00 L. Fitton (Shaw, Lancashire, UK, 8.5"
reflector, x200, Wratten 25 and 44A filters, seeing II-III,
transparency, good) noticed in Aristarchus, blue to the north west
(IAU?) internal wall, also blue observed in other small bright objects
against dark backgrounds. Lunar rotational axis and optical normal
related such that the normal runs NW-SE (IAU?) through these features.
Observer deduced that the coliur was obviously spurious and no blink
was seen in any feature. The blue disappeared as the lunar altitude
increased and no blue seen by 00:00UT. This is a BAA lunar section
observation. The ALPO/BAA weight=1.
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 1994 Apr 25 at UT11:08 B. Soulsby (Australia) found a darkening on
the north floor of Copernicus crater. The ALPO/BAA weight=1.

On 1901? Nov 25/25 at 23:00UT Besanceas (France?) observed: "During
lun. ecl. (mid-ecl. at 0118 on 26th) a bright area seen on moon.
Another(?) obser. saw an obj. like a fiery comet leave the moon! (Date

On 1898 Jul 03 at UT 21:35 Moye (France) noted that 30 minutes after
mid eclpise, Proclus shone with a reddish light in shadow. The Cameron
1978 catalog ID=301 and the weight=2. The ALPO/BAA weight=2.
On 1970 Aug 17 at UT 02:40 Pedler (England) noted that the
shadow flowed around instead of over Plato. Wondered if shadow
matched the gray of the crater. Within minutes the shadow line
looked normal again. At 04:41UT Claudio Pamplona (Brazil) saw a
pulsation in Plato during a lunar eclipse. He thought that this
was due to falling temperatures. The Cameron 1978 catalog ID=
1274 and the weight=0. The ALPO/BAA weight=1.
Cauchy 1969 Jul 29 UT 06:00-06:22 Observed by Claudio
Pamplona and Jackson Barbosa (Fortaleza, Brazil, 2"
refractor) "very bright and clear(?) pulsating 3,3s,3s with
crater illum. then 3s area illum. red & no filter area
pulsated for 22m. Confirmed by Jackson (Apollo 11 watch)".

Plato 1921 Nov 15? UT 20:00? Observed by Chernov (Russia, 2" refractor
x94) "Temporary increase in brightness of the light band at bottom
noted close to FM. Crater actively noted in Oct. 10." NASA catalog

On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by N. Hazel
(Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max,
with 2x teleconverter, at f9, 1/320 sec, ISO 400 – tripod
mounted, mirror up), A series of images were taken. The 21:06 one
showed a grey column cutting across the central floor of the
crater from the west and then bisecting the eastern rim. All
detail inside is completely invisble. Some (but not all) of the
other images showed a more blurred view of this feature. It's
possible that this was a seeing ripple effect, or just the
natural appearance of shadings on the Moon at this time, however
for now this will be given an ALPO/BAA weight of 1.
On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade
2045 reflector, x40, seeing=turbulent) detected flashes coming from
just north of the centre of Mare Tranquilitatis. Some of these flashes
were of a duration of seconds whilst others were several minutes.
Altogether ~20 flashes were seen, and not in the same place. "5 small
star-like points could be located - and there were lots of craterlets".
The spots were "lined up E-W at N of 10 deg latitude." Colour was not
visible on these nor variations. Apparently the observer had seen this
type of TLP before but had not reported them. The Cameron 2006 catalog
ID=323 and weight=2. the ALPO/BAA weight=2.
On 1956 Nov 19 at UT 00:00? an unknown observer (Cameron gives an AGU
meeting reference) apparently saw a TLP in Aristarchus crater. The
Cameron 1978 catalog ID=657 and weight=0. The ALPO/BAA weight=1.
On 1970 Aug 12 at UT21:00? an unknown observer commented about Plato:
"Light #22, remarkable increase in brightness. #32 subsided & #14 shone
out then faded & #16 brightened. (Fort says that till Apr. 1871 selenog
recorded 1600 obs. of fluctuations of lights in Plato & had drawn 37
graphs of indiv. lights. These were deposited in the library of the
Royal Astronomical Society by Birt)." The Cameron 1978 catalog ID=169
and the weight=3. The ALPO/BAA weight=2.
On 1975 Dec 19 at UT22:45 P.W. Foley (Kent, UK) suspected an anomaly in
Aristarchus. Cameron 1978 catalog weight=1424 and weight=1. ALPO/BAA

Gassendi 1967 Sep 20 UT 21:11-21:46 Observer: Moore & Moseley
(Armagh, N.Ireland, 10" refractor, x254) "Faint blink & red
glow SSW of c.p. at 2111h. At 2118 was fading & moving
slightly N. Gone at 2110. At 2122h suspected blink close to
SW of c.p. Gone at 2123h. At 2143 both obs. suspected a faint

ALPO/BAA weight=1.
On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector,
x260) saw at 01:25UT an unmistakable red-orange glow on the south and
south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected
it easily. At 01:33UT the colour was barely visible. No TLP alert was
issued because the souther edge of Mons Pico also exhibited a hint of
colour, and anyway the seeing conditions were poor. Despite this no
other features revealed colour. The Cameron 2006 catalog ID=446 and the
weight=0. The ALPO/BAA weight=1.
On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector,
