Archimedes 1973 Jun 11 UTC 21:05-21:15 observed by Pasternak (53deg
20'N, 7deg 30'E, 75mm reflector) "Faint red area at the E of Archmedes,
diminution from 21.10-21.15UT" - Hilbrecht and Kuveler, Earth, Moon &

Om 1987 Sep 04 at UT 03:00 J. Caruso (Middletown, CT, USA, 3"
refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not
visible, however Heraclides E, Helicon G, and indeed many other smaller
craters could be seen. There were two small mountains in the general
area of Bianchini G. and a mare ridge - all these were clearly seen.
Caruso states that Bianchini G should normally be much more clearly
seen than the other features mentioned and is the same size as
Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3. The
ALPO/BAA weight=1.
Gassendi 1966 May 30 UT 20:32-20:59 Observed by Sartory (England, 8.5"

On 1955 Jan 05 at 01:00-01:30 UT D.A. Logue (Larchment, PA,
USA, 15cm reflector at x340, seeing Good) saw a strange blue
light above the surface of the Moon where the night and the
day meet. He observed this light for more than 30 min and it
did not appear to move. It appeared like a star in that the
rays of light came from it. The observer adds that he first
thought thst the objects was a star, but later decided that it
had to be on the Moon itself. A drawing shows the blue spot
near the rugged south west (IAU?) limb of the Moon. The editor
of the Strolling Astronomer (Vol 8, No. 11-12, Nov-Dec 1954,
p146) was unable to identify the craters drawn. The editor
speculates that the observer saw a high mountain peak with its
summit in sunlight and detached from the illuminated regions -
however this would not explain the blue colour. Note this is
an ALPO observation and does not apear in the Cameron
catalogs. ALPO/BAA weight=2.
On 1964 Jun 21 at UT 03:43-05:44 Harris, Cross and Helland (Whittier,
CA, USA, 19" reflector) observed south of Ross D: "Moving dark area".

On 1982 Aug 01 at 00:00-01:00 K. Marshall (Medellin, Columbia, 12"
reflector, seeing I-II) noted shading on the east floor of Plato that
was apparently lighter than the rest of the floor and this was seen at
both low and high magnifications. Foley notes that this was unusual.
There were three craterlets visible on the floor - the central one was
the brightest. Cameron 1978 catalog ID=178 and weight=3. ALPO/BAA
weight=1.
A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and
definition fairly good. Observer noticed that the Mare seemed covered
with a close network of innumerable streaks, and spotted with countless
numbers of light specks, so that it would hardly be possible to
delineate them all in one night. The spots and streaks together must
have numbered ~1000. The observer had never seen anything like the
number of spots and streaks. Peirce A, was not at all easy to se and
neighboring spots almost as bright made it difficult to distinguish
which one was Peirce A. ALPO/BAA weight=3.
On 1976 Apr 10 at 21:15-21:49UT S.Spencer (60mm refractor x60, seeing
quite good) noticed a faint red glow at the south west wall of Gassendi
covering a span of about 35 deg arc. The observer had some doubts about
this because they were using a small telescope, but thought that they
ought to report it, just in case. A BAA Lunar Section report. ALPO/BAA
weight=1.
On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector)
and at the same time Doherty (Sussex, UK, 15" reflector) observed a
strangely bright and pink/red north rim of Aristarchus crater during
UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT.
M.C. Cook (Frimley, UK) found the northern wall to have a red/purple
colour but the effect vanished after 50 minutes. Cook also saw a "V"-
like notch in the NW crater shadow and this appeared to be bigger than
normal. G. North (Sussex, UK) saw a tinge of pink colour on the
northern rim and a bit later a "ruby red" colour on the north-west wall
- again this effect lasted 50 minutes. Moseley verified the colour.
Finally M. Hather (Yorkshire, UK) suspected the north wall of
Aristarchus to be blue in colour. Cameron suspects that this TLP is not
spurious colour because it is in the wrong place. The Cameron 2006
catalog ID=276 and the weight=5. The ALPO/BAA weight=4.
On 1985 May 30 P.Madej (Huddersfield, UK, 77mm refractor, x111
and x250, seeing II-III, transparency good) whole spectrum of
colours seen on the central peak area, visible in both
eyepieces, and was more prominent at the higher magnification.
Not aware if the observer checked for this effects on other
terminator peaks? xALPO/BAA weight =1.
On 1991 Jan 26 at UT 23:38-23:50 D. Darling (Sun Praire, WI,
USA, 12.5" reflector, x159 and 3" refractor x90, seeing 5/10,
transparency 3/6) found that Aristarchus was brighter through
a red filter than through a blue filter on its western wall.
He checked Aristarchus in two telecopes and obtained the same
result. The Cameron 2006 catalog ID=419 and the weight=4. The
ALPO/BAA weight=3.

Aristarchus 1982 Nov 27 UT 20:13-01:00 J-H Robinson (Teighmouth, Devon,
UK) found that the bands of Aristarchus were clearer in red than in
blue light. North found that the sunlit part of the crater was very
bright. M. Cook described the crater as a "kaleidoscope of colour.
Foley observed UT 23:05-01:00 (Kent, UK, Antionadi III, Transparency

Cameron 2006 catalog ID=190 and weight=5. The ALPO/BAA weight=3.
On 2017 Sep 02/03 UT 23:55-00:30 A.Anunziato (Parana,
Argentina, 105 mm Maksutov-Cassegrain, x154, seeing 6/10, some
interuption from clouds) observed a light spot SE of the
centre of the floor of the crater, which came and went in
visibility. There is a light spot here, but what was unusual
was that the visibility decreased over time.
ALPO/BAA weight=1.
Herodotus 1950 Mar 30 UT 19:00? Observed by Wilkins (Kent,
UK, 15" reflector) "Transient c.p. (similar phen. to

On 1997 Oct 13 at UT11:09-11:21 D. Rodway (Oamaru, South Island, New
Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in
the south east corner interior of the crater Aristarchus. This colour
was confirmed by the observers wife. By 11:21 UT the colour had faded
completely. Rodway had been a lunar observer since 1958, using a wide
range of instruments from 3 inch refractors to 12 inch reflectors and
had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so
was an experienced observer. The ALPO/BAA weight=4.
On 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector,
seeing III-IV) found that LaPlace A was significantly more prominent
than usual - comparisons were made with photographs in books. The
Cameron 2006 catalog ID=178 and weight=3. The ALPO/BAA weight=1.
On 1993 Jun 02 at Ut 04:30-05:45 S. Beaumont (Cambridge, UK) saw that
the shadow of the Cobra's Head in Schroter's Valley was lighter and
more diffuse seen at user defined locations of C or B rim (these were
black versus medium gray for Cobra's Head). The TLP had vanished by
05:45UT. The Cameron 2006 catalog ID=462 and weight=3. The ALPO/BAA
weight=1 because the date or time is wrong.
On 1984 Nov 05 at UT18:00 Marshall (England) noted that there was no
normal brightening on the floor just next to the southern most
craterlet. The Cameron 2006 catalog ID=251 and the weight=2. The

On 1994 Apr 23 at UT02:41 D. Fryback (Madison, WI, USA) observed a
starlike flash in Alphonsus crater. The ALPO/BAA weight=2.
On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit
around the Moon, obtained images of the Cobra Head region of
Aristarchus crater that suggested a ~15x colour ratio increase (0.4
microns / 1.0 microns) in comparison with images obtained on 1994 Mar
03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting.
However it was later suggested that this was due to incorrect
radimetric calibration procedures being followed. The ALPO/BAA
weight=1.
On 2004 May 01 at UT 22:20 R. Lena (GLR, Italy) received an image from
one of his observers showing possible blue colour in Aristarchus crater

very bright. However the colul had gone by 20:29UT. "Varied in albedo
2s then image blurred at 5-10s (atm) at 2034 became pink). At 21:35UT
M. Mobberley (Suffolk, UK) found a white patch in the crater centre and
a mag 8 flash was seen (confirmed independently by a 2nd observer ~
113km away)- there was no shadow. At UT 20:30 P.W. Foley (Kent, UK,
12"reflector, seeing excellent) found no colour, but the brightness was
changiong and he confirmed the bright patch on the crater's floor,
variable 22:15-22:25UT, "then expanded over rim". The Cameron 2006

Antionadi III, Transparency Moderate) - Colouration Seen - Ref: BAA
Lunar Section Circular. ALPO/BAA weight=2.
Aristarchus 1975 May 23 P.W. Foley (Wilmington, UK, 12"
reflector, x200, x360, x624, atmospheric clarity good, seeing
III from 20:15-22:30, but the clouded out at 22:30, and from
23:15-01:15 seeing was IV-V with poor transparency) observed
(22:20-20:45 UT) variation in the SE corner of the
Aristarchus, namely the usual dark bands were alternating
light to dark, not in keeping with otyher crater features.
This effect was not linked to atmospheric turbulence. Also
projected image of bands beyond the crater W. wall were
repeatedly noted. The observer broke away from observing at
20:45UT to make a telephonealert call. At 20:55UT they noted
that the area between Vallis Schroteri and Herodotus seemed
very light/bright, also the E. exterior of the crater wall of
Herodotus. From 21:01-21:11 A slight blueness was seen to
extend from the NE corner of Aristarchus, along the exterior
rim, acrossand beyond Herodotus to the SW. A tgorough search
was made of many bright areas, both near the terminator and to
the E., but no blueness could be detected elsewhere. A slight
orange hue was noted along the E. limb of theMoon (Spurious
colour). From 21:18;22:30 Aristarchus seemed normal again, and
likewise the head of Vallis Schoteri too. The observer was
clouded out from 22:30-23:15and from 23:15-01:30 the seeing
was so appaling that no colour or projection of the bands
could be seen. A Moon Blink was used during the session, but
no colour was detected in this? Another observer, R.W. Rose
(Devon, UK) observed 21:20-21:30 but had IV seeing, and saw
nothing unusual, but commented that if TLP wactivity had been
taking place, then they would probably not have seen it. The
ALPO/BAA weight=1.
On 1964 Jun 23 at UT 04:45-05:05 Bartlett (Baltimore, MD, USA, 5"
reflector, x180, S=4-1 and T=3) observed a blue-violet glare on the
north east rim and a strong violet tinge in the nimbus. The effect was
absent 1 hour earlier. The Cameron 1978 catalog ID=821 and weight=4.

Aristarchus 2015 Mar 03 UT 23:58 Brendan Shaw (UK) saw a flash
on the NW rim of Aristarchus on his computer screen - the camera
was working in the near IR. Seeing was not very good at the
time. Unfortunately this flash occurred in between imaging
sessions. No other flashes seen, despite looking. The observer
considerd the possibility that it might have been a cosmic ray
detection, but cannot say for sure. The ALPO/BAA TLP weight=1.

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

(this is not normal as it is usually bright in blue - according to
Cameron). The brightness was 9.7 (red) and 9 (blue no filter)compared
to Eimmart's 8.7. Louderback thought that they observed an oranfe-
yellow tinge. Cameron 2006 catalog ID=108 and weight=3.
1999 Jan 07 UT 01:57 C. Brook (Plymouth UK, 65mm refractor,

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 1981 Dec 19 at UT 01:00-05:00 E.V. Arsyukhin (Moscow, Russia, 3"
reflector) observed that Plato was consdierably brighter than
Aristarchus by several times. The image quality was very clear. The

158mm reflector, x72 and x110, seeing II, transparency fair?)
saw a small circular area of grey or white in the dark south end
of Copernicus.The area showed up better through a Wratten 15
yellow filter, but was not seen at all through a purple Wratten
35 filter. P.W. Foley (Kent, UK), confirmed this but thinks that
it is normal. Cameron 2006 catalog ID=68 and weight=1. ALPO/BAA
weight=1.
Copernicus 1979 Sep 15 UT04:40-05:25 J.Saxton (Leeds, UK,
8.5" reflector, x185, seeing I-IV, worsening towards local
sunrise) made a sketch and noted that the northern tip of the
internal shadow, by the floor, was not completely dark. The edge
of the floor here could be distingished, even though it was in
shadow. ALPO/BAA weight=1.
Closest parts of the Moon at Saturn appearing from
occultation were dull and hazy. Was this an effect of
the lunar atmosphere or a high haze and halo around the Moon?
Cameron's 2006 catalog extension gives this an ID No. of 3
and a weight of 1. The ALPO/BAA catalog weight is also 1.

moments of atmospheric seeing conditions. A spectra was taken but
nothing unusual was seen. The Cameron 2006 catalog ID=284 and the
weight=1. The ALPO/BAA weight=1.
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.
"Suddenly some flashes of light streaked across dark surface,
but definitely within the limbs of the moon's outline. Then
repeated at least 6-7x during 20-30 min (~every 5 min).

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.

Adams D On 2019 Sep 06 UT 21:44-22:20 T. Smith (near Great
Yarmouth, UK, 90 mm Maksutov, x80, Seeing IV) saw a very
bright spot on the SW. rim of Adams D - at first sight looked
perhaps raised above the lunar background, but this was just
due to its brightness. It was by far the brightest object on
the NW quadrant of the Moon. In terms of brightness it was
almost but not quite bright as Proclus, but only half the sie
of Proclus. No colour was seen to the spot. The spot was not
emitting any false colour, there was no change in appearance,
and there was no ray structure visible either. Observations
ceased when the Moon got too low. ALPO/BAA weight=1.

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

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 2009 Apr 04 at UT 20:30-20:45 C. Brook (Plymouth, UK) observed a
slight pinkish mottling on the floor of Plato. The effect was no longer
visible after 20:45UT. A telephone alert was put out to M. Cook and G.
North. The former saw no colour, but this was after the event finished.
The latter observer reported cloudy conditions. A.Cook was probably
observing at the same time as C. Brook, via a couple of remotely
controlled telescopes in Aberystwyth. The results (time lapse imagery
through narrow band filters) will be examined at a later date.
Plato 1972 Mar 24/25 UT 20:38-00:00 Observed by M.Burton (UK,
13.5" reflector, seeing IV-V, Transparency Fair, x180) UT20:38-
20:45 floor was darker in a red filter than in a blue. UT20:47-
20:56 JS Burgess (seeing 2/5, x200, with and without filters)
found everything normal (with and without filters). UT20:00-
20:07 and 21:30-21:35 A.J. Beddoes found everything normal (with
and without filters). However at 23:10 L.Fitton suspected that
the E (IAU?) floor of Plato had a red-brown cast, but could not
be quite sure. UT23:54-00:00 M.Burton, detected the floor was
darker in red than in blue light. Burton did not detect any
colour without the use of filters on either of the two occasions
that he detecetd a blink. In view of the fact that two observers
did not detect anything, albeit not concurrently with the TLP
reports, this TLP is being given an ALPO/BAA weight of 1.
On 2009 Apr 04 at UT 21:40 M.C Cook (Mundesley, UK) after receiving a

report C. Brook's slight mottled pink on the floor of Plato, she did
report through that the floor patches looked darker than normal,
especially in blue light and in red they were not visible at all. In
white light they were darker than normal. A.C. Cook was probably
observing at the same time via a couple of remotely controlled
telescopes in Aberystwyth. The results (time lapse imagery
through narrow band filters) will be examined at a later date.
Note that this observation was made after C. Brook said that he could
no longer see his TLP. Therefore this constitutes a different TLP
as there had been a gap of 1 hour since the last TLP report.
On 1982 Aug 29 at UT 02:13-02:30 Robotham (Springfield, ON,
Canada, x97 and x160) found that the west rim of Pytheas crater
was very bright, especially at lower magnifications, being one of
the brightest spots on the Moon. The Cameron 2006 catalog ID=182
and weight=3. ALPO/BAA weight=1.
Scarcely a trace of nebulae tonight. As long as to June 10 at
2000UT? A little blackness remained. (P. Moore thinks it
was a LTP, WSC it was a permanent feature?) Drawing. Seen
by Nevelius Emmett, J. Boroughbridge, England. The 2006
Extension catalog by Cameron assigns an ID No. of 4 and a
weight of 1. The ALPO/BAA weight=1.
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
crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5.
The ALPO/BAA weight=3.
Sinus Iridum 2004 May 29 UT 20:44 Observed by Clementelli (Rome, Italy,
102mm diameter Vixen refractor 80-160x, sky conditions: clear, no wind)
"A blue/violet streak, lasting ~10 minutes was seen on the floor of
Sinus Iridum between crater Bianchini and Promontorium Heraclides. The
suspect TLP mybe an effect of instrumental achromatic aberration, but
there is the small possibility that the effect was real." A UAI
observational report. The ALPO/BAA weight=2.
On 1983 Aug 19 at UT 07:15-07:30 D. Louderback (South Bend, WA, USA,
3" refractor, x150) found that the direct sunlit side of Mons Piton
mountain (E) was brighter than (his designated) points C and D and this
happened at the same time as some "blurring"at 07:15UT. The darker
side, between C, A and B were not so dark through a red filter as
through a blue filter (this was the opposite of what had been seen
before at a high sun angle). Louderback suspects that there had been a
colour change since he last observed. He also noted that in red light
the whole lunar disk appeared fuzzy and out of focus. Louderback noted
a 1 sec brightness on the east slope and the whole mountain sharp in
blue light. The Moon's altitude was low though. Brightness measurements
were 4 in blue light and >= 4.6 in red light and "so illdefined almost
blended into plain". Cameon commnets that a telescope colour/focussing
issue may have been at work here! The Cameron 2006 catalog ID=226 and
weight=4. The ALPO/BAA weight=1.
On 1989 Jul 14 at UT 03:28 D. Darling (Sun Praire, WI, USA) found a
darkening in the crater Proclus, but the shadow seen by Cook and Moore,
from a few hours earlier was not seen. The Cameron 2006 catalog ID=371
and the weight=2. The ALPO/BAA weight=1.
Parry 1974 April 03 UT 01:10-01:45 Observed by Porter (Narragansett,
Rhode Island, USA, 6" reflector, S=F, T=2) "Darkening of floor &
brightening of central crater. Pulsations for 1 min. Albedo of LTP=2
(fl.), 6.5 (c.p.). Normal floor=3?. Floor seemed darker than earlier &
approached surrounding plain(=2) while N-S streak seemed more
conspicuous. Pulsations same freq. as star excursions so prob. due to
terr. atm. aberr. Streak most conspicuous at 0145h" NASA catalog
weight=2 (poor). NASA catalog ID #1391.
Archimedes 1979 Oct 01 UT 20:57-21:00 Observed by Cook (Frimley, UK,
13mm Monocentric + Barlow eyepiece, Seeing IV, transparency: thin
cloud) "Red seen on east, blue seen on west - almost certainly spurious
colour".
Bullialdus 1979 Oct 01 UT 21:04-21:07 Observed by Cook (Frimley, UK,
13mm Monocentric + Barlow eyepiece, Seeing IV, transparency: thin
cloud) "Red seen on east, blue seen on west - almost certainly spurious
colour". ALPO/BAA weight=1.
Alphonsus 1959 Feb 18 UT 21:00? Observed by hole (Brighton,
England, 24" reflector) "Red patch (Moore in Survey of the Moon
says Jan. '59). Moore says, Warner, in Eng. saw it bright red in
an 18-in refr. Hedervari & Botha in Hungary saw red patch &
several in US (indep. confirm. ?)" NASA catalog weight=5. NASA
catalog ID #714. ALPO/BAA weight=5.
On 1991 Feb 25 at UT 01:26-01:49 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x248, seeing=10/1, transparency=good) found
Gassendi's western rim to be bright in red and diffuse in blue
light. A sketch was provided. The Cameron 2006 catalog ID=420 and
the weight=4. The ALPO/BAA weight=2.
Plato 1967 May 20 UT 01:13 K.Simmons (Jacksonville, FL, USA, 10"
reflector) observed a large bright (intensity 6.5) oval area on
near the central floor. According to Ricker and Kelsey (ALPO
selected area coordinators) this is unusual. ALPO/BAA weight=1.
On 1979 Dec 29 at UT 17:45-18:20 Crick (Merchtem, Belgium, 6"
reflector, x140, seeing=III) found a violet spot in the NW inner wall.
The floor was obscured of detail on the northern half. All other
regions studied appeared normal. Observer unsure if this was a TLP or
spurious colour. Cameron 2006 catalog ID=80 and weight=3. ALPO/BAA
weight=3.
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
areas were seen on the SE and NE rims. 4 of the observers did not see
colour. Independent confirmation was made by Don Spain (KY) and Smith
in LA. Full details can be found on the following web site:
http://www.ltpresearch.org/ltpreports/LTP19890715.htm " An ALPO report.
On 1978 Jan 20 at UT19:10 P.W. Foley (Kent, UK, 12" reflector) observed
a red spot at the southern edge of Gassendi C. P. Moore (Slesey, UK,
15" reflector, S=II-III) reported nothing unusual 17:00-17:50. Turner
and others reported negative at 22:01. Pedler (UK, 12.5" reflector,
S=III-IV) though detected a yellow-orange tint on the east floor of
Gassendi A but the effect faded during poor seeing moments. Cameron
2005 catalog ID=24 and weight=5. ALPO/BAA weight=3.
Aristarchus 1967 May 20 UTC 20:15 Observed by Darnella (Copenhagen,
Denmark, 3.5?" refractor) "Red spots on S.rim. Moon was low." NASA
catalog weight=1 (very low). NASA catalog ID #1036.
On 1969 May 28 at UT 02:18 Delano (Taunton? MA, USA, 12.5"
reflector, x300, seeing=fair and transparency=good) through the
red filter at 02:18UT saw a bright area on the west wall of
Aristarchus crater become 2x brighter than normal then faded
back to normal in < 1 min duration. The spot was 8km centred on
sigma=0.682 and eta=0.397. No events seen at Kepler (Apollo 10
watch). The Cameron 1978 catalog ID=1149 and weight=4. ALPO/BAA
weight=3.
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 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
c.p. Similar effects seen on other craters. (madej) c.p. & W. rim wall
very sharp. c.p. disappears in yellow but still seen in purple.
(pedler) c.p. > red than blue but no obstruction. W wall interior
dusky, darker in blue." A.C. Cook's photo depicts the central peak as
very bright. Cameron 2006 catalog TLP ID=120 and weight=5. ALPO/BAA
weight=2.
On 1969 May 28 at UT 02:18 Delano (Taunton? MA, USA, 12.5"
reflector, x300) suspected a short duration flare up on the W
wall of Aristarchus at 0.682 and 0.397, but it may have been due
to poor seeing. No events seen at Kepler (Apollo 10 watch). The
Cameron 1978 catalog ID=1149 and weight=4. 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 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.
Aristarchus 1969 Jul 26 UT 02:15-03:00 Observed by Jose L. da
Silva (Rio de Janeiro, Brazil, 13" refractor) "Unusual
brightness whole time in center of W. inner slope; rest of
crater & Herodotus appeared normal. SW to NW inner slope had
pronounced brightness. Aris. still in dark! Apollo 11 watch)."
NASA catalog weight=3. NASA catalog ID=1186. ALPO/BAA weight=1.
Aristarchus 1969 Jul 26 UT 02:30-03:00 Observed by Mauro Migon
(19" refractor), Julio Nogueira (10" refractor), Wairy Cardoso
(13" refractor) all from Rio de Janeiro, Brazil "Crater was
gray-bluish, different from any other region & unusually bright.
Cardoso saw brightening, used blue, red, green & neutral
filters. Apollo 11 watch, Jose da Silva says obs. no good, obs.
was inexperienced. However it is similar to many other obs. with
much experience)." NASA catalog weight=2. NASA catalog ID
No. 1187. ALPO/BAA weight=1.
On 1992 May 13 at UT 22:30 R. Turner (Wolverhampton, UK, 3.6"
reftactor, x50) noticed that there was a white spot on the WSW rim that
he had not seen earlier. The Cameron 2006 catalog ID=445 and weight=5.
ALPO/BAA weight=1.
Aristarchus 1971 Mar 08 23:00-23:10 Observed by Lyttle (Northern
Ireland, 6" reflector, x98) "Suspicion of white spot W of N-S radial
band, slightly brighter than wall. Diam. @5-6km. Area affected by temp.
?Term. passed over it just 5h before. Gradual decline in brightness
over the 10m period." NASA catalog weight=1 (very low). NASA catalog ID
1288.
Pico 1976 Mar 12 UT 21:00? Observed by Findlay (England?) "A ray seen
extended fr. mt. in SW (IAU?) direction -- likened to a hockey stick.
(not seen in Pickering's photo atlas at col.=53 deg)." NASA catalog
weight=3 (average). NASA catalog ID #1430.
Gassendi 1951 May 17 UT 22:45 Observed by Wilkins (Kent,
England, 15" reflector) "Bright speck glowed for 3s. (meteor ?)"
This was to the W of the central Mts and about the same
magnitude as a 4th mag star to the naked eye. JALPO Vol 5 No 8
p4, quotes a 1s duration. NASA catalog weight=0. NASA catalog
weight=544. ALPO/BAA weight=1.
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
vis. within floor shadow. Peak est. 5 bright. Had seen it at successive
lunations in '66" 4" x280 refractor used. NASA catalog weight=4 (high).
