Cassini E 2002 Dec 11 UT 16:30-18:46 Observed by Knott (Liverpool,
England, 216mm Newtonian, x216, red and blue filters used) seeing III,
transparency good) "Observations carried out of the area extending from
the Alpine Valley to the Crater Cassini. At 17:12 a pin point bright
flash was seen NW of the rim of the crater E in white light. A 2nd pin
point flash was also seen at 18:18, this time thru a blue filter. The
2nd flash was also seen on the NW rim of the crater E. The observer
does not think this was a TLP as the seeing was III, but the flash was
so bright as to be startling. Other peaks within the Alps were bright
but were much less so in red and ble filters, where the rim of the
crater E. NW edge was very bright in all filters, including white
light. Incoming cloud prevented further observation." BAA Lunar Section
report.
On 1982 Dec 22 at UT 19:20-20:10 J-H Robinson (Teighmouth, Devon, UK,
10" reflector, x150, seeing=IV-V) could not distinguish between Messier
and Messier A. The tail of these features was very bright - two
telescopes were used. Moore (Selsey, UK, 12" reflector, seeing=III)
could see Messier A but found Messier itself obscured - just see the
west wall and thought that the comet like tail was unusual as it did
not appear divided. The Cameron 2006 catalog ID=192 and weight=5. The

Lancashire, UK, 76mm f/16 refractor, x170, Wratten 25, and 44a
Moon blink filters used, Transparency 4.5/5, no wind, S=F). The
west flank of Maginus, and the interior, appeared to be partly
obscured. No other features in a similar position along the
terminator were obscured. No colour blink was detected with the
filters, though a pronounced red/white light blink was noted; the
device employed a N.D. x4 filter. By 21:45UT the floor was no
longer obscured and only Magninus G was masked in a white haze;
however immediately adjacent to the terminator was an ill defined
misty patch lying where the outer flank of maginus would have
been visible. The rest of the terminator was sharp. The
obscuration was only seen to advantage in blue and int. light,
and the blue/int blink was only very slight. Findlay and
McDonnell observed 21:30-23:00 using a 25cm refractor (Seeing II-

77mm refractor, x83,x250, seeing II-III, transparency fair).
After studying the whole length of this valley, the observer saw
a change in "albedo" and a small change in colour of the valley
floor near to the Plato end. This colour was not seen in a
yellow Wratten 15 filter but was noted in a purple Wratten 35

On 1977 Apr 29 at UT21:40-23:20 an unknown UK observer reported a TLP
in Gassendi crater. The following are reports by observers attempting
to confirm activity: J.W. Napper (Didcot, UK, 30cm reflector, x287,
Wratten 25 and 44a, conditions clear 5+) received a telephone alert
call at 22:00 but the sky was cloudy until 22:30. An initial look
revealed nothing unusual, then at 22:54 he observed a colour blink just
inside the north wall, appearing bright in red and normal in blue or
white light. No loss of detail seen and the effect lasted only 2
minutes. A sketch was made. However the observer stresses that the very
bad seeing casts some doubt on this observation. L. Fitton observed
using a 8.5" reflector, with Moon blink device at x200, seeing was I-
II. All areas negative, including Gassindi from 21:40-21:55 and again
22;00-22:25 and finally 22:50-23:30 negative. Mike Brown (Huntington,

Gassendi. He had been observing earlier at 18:40-19:30 but had not
detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot
outside the east wall is again bright in red., though by 22:25 it had
faded and was gone by 22:28UT. The Cameron 1978 catalog further
quotes: "Vivid red spots & general red color seen around rim by 2 obs.

upto the wall) to be quite dark in blue light, but normal brightness in
red light or in white light. All other features were normal colour-
wise. At 22:55UT Tycho was normal again. Cameron 2006 catalog ID=103
and weight=4. ALPO/BAA weight=3.
On 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st
7:24PM PST) saw a naked eye flash on the Moon. The observers were
glancing up at the Moon in daylight when they saw a bright white flash
(observer and his wife together) in the upper/mid Mare Serenitatis
region, west of the crater Posidonius. "Larger than how Venus appears".
"It was a quick flash like white, intense lightning. I'm not sure how
to report degrees of arc but if the face we see is 900, and we start
from the east then the flash occurred about 225 arc seconds to the
west. This was observed by the naked eye, with clear skies between us
and the moon." The observers checked for signs of aircraft vapour
trails but could not see any. There is a possibility that it could have
been sun glint from an Iridium satellite, but this needs to be checked
out and usually these last longer than the observed effect. It would be
useful to obtain whole Moon images under the same illunination and
libration so that we can judge this observation properly. The ALPO/BAA
weight=4.

that the TLP referred to might have been
from the 1783 Mar 18 eclipse instead?
On 1881 Dec 05 at UT 17:09 Johnson observed a dark lunar eclipse.
Aristarchus was seen as a white spot in the coppery disk and continued
so. Cameron comments that this is the normal apeparance in an eclipse?

On 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW,
Australia, 8" reflector, x100, x160, S=III) observed a bright star-like
point on the western (IAU) edge of Mare Tranquilitatis (x100) that
appeared unlike any other crater and a check of the location revealed
no suitably bright crater in that region (from a map?). Changed to a
higher power (x160) and it was still there, but not as conspicuous.
Observer thinks that this may have been due to the Moon's low altitiude
(16 deg) and the seeing. At 18:35 he compared it to the brilliant
crater Proclus and found the star-like point to be 75% of the
brightness of Proclus. Ken Wallace (Australia) had been taking photos
and observed the object at 17:37.5UT. The object gradually faded over
the next 15 minutes and by 18:52UT could only be seen in averted vision
at x100. By 18:57UT it was gone. The Cameron 2006 catalog ID=38 and
weight=5. The ALPO/BAA weight=3.

On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK,
seeing=IV-V, transparency=good, spurious colour seen) found 2
bright pathces on the east rim on alternate sides of a bright region.
The band from the central 16km wide region was dark on the east side.
Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be
not as bright as normal, apart from the band that Mobberley found (1
hour later). The dark regions were a murky green colour (bright through
green, blue and yellow filters and dark through red and orange
filters). Cook (Frimley, UK, transparency=excellent, CCD camera used)
found a bright "bulge"on the eastern side. Apparently data suggests
that the band was brighter in red than in near IR light. Cook's
calibrated brightness measurements suggest that there was no change in
brightness over the crater with time. Two other bright points were
seen: one at the Cobra's Head and another half way between the east rim
of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87
(near IR) and combined Wratten 29 and Wratten 87 were used. In the red
Wratten 29 filter the brightness falls at22:20 at Shroters valley and
then rises in the bright ray. They return to normal at 22:30UT. There
was however a lot of measurement noise from the brightness readings of
points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The
ALPO/BAA weight=3.
On 1963 Dec 30 at UT11:00 many observers reported seeing a red glow on
the North East (IAU?) limb of the Moon. This was also captured on a

On 1953 Jan 29/30 UT 23:00?, 01:00? Dubois (Floirae, France) observed
excess luminescence, in Mare Fecunditatis, between 420nm and 470nm
(maximum at 435nm) and between 480nm and 520nm (maximum near 505nm).
20-60% during eclipse at 50' from the centre of the umbra, during a

ALPO/BAA weight=4.
On 2000 Jan 21 UT04:40 G. Emersen (Golden, CO, USA, 30cm focal length
lens with Wratten 25 ref filter) took 43 CCD images of the eclipse of
the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively
bright spot appeared in the southern part of Mare Fecunditatis. The
spot looks sharper than the rest of the Moon and so might be a cosmic
ray? CCD images taken from Washington D.C. by A.C. Cook at this time,
do not show this spot, however exposures were at intervals of 0.25 sec
and so might have missed this spot if it happened during image readout.
The ALPO/BAA weight=1.
On 1953 Jan 29-30 UT 23:05-01:40 G. Brown (UK?) observed a white patch
of light of low brightness was seen to move around the north polar

On 1877 Feb 27 at UT19:19 Prof. Dorna (Turin, Italy) observed a
flickering light on the lunar surface during a lunar eclipse. The
Cameron 1978 catalog ID=186 and the weight=2. The ALPO/BAA weight=2.
On 1848 at UT 21:00 Rankin and Chevallier (France?): Luminous pts. seen
during an eclipse. Cameron ays that year 1847 given by Middlehurst must
be wrong as age is 2.7 days for this date in 1847 and could not be 18-
19 as in Middlehurst because eclipse is on the 19th at 21h (mid) in
1948. aux. data here are for 1848. At 21:12 Forster (England) and
Bruges (France) observed rapid changes in red colour. The Cameron 1978

refractor, x117 & x40, seeing good, transparency excellent)
observed abright spot on the north rim of Mare Crisium (57E,
25N). It was comparable to the illuminated rim of Proclus in
brightness. No colour seen. The spot was not visible the next
night. The ALPO/BAA weight=1.
On 1895 Mar 10 L. Swift et. al (Lowell Observatory, Flagstaff, AZ, USA)
and Elger et al. (England), observed during a total lunar eclipse that
Aristarchus was glowing with brilliance never seen before. This

On 1975 Nov 18/19 at UT 23:15-0005 LeCroy Jr and Sr (Springfield, VA,
4.5" reflector, S=7) observed that Menelaus was one of four glowing
spots on the Moon during a lunar eclipse (including Aristarchus). At
23:50UT 3 of these patches emerged from the dark and appeared as bright
spots compared to other craters "Älbedo=10+". At 23:55UT a ray appeared
out of the north east rim of menelaus (Normal?). It appeared just
before the artea emerged and increased in brightness. At 23:58UT it
decreased and continued to do so. The north east edge of Menelaus
appeared very dark at the point that the ray was extending from SW edge
(a ridge there) and apperared to obscure features along its path
(Albedo=9). The Albedos of Manilius and Delambre were 8.5 at 00:05UT.

observed that Aristarchus did not appear normal for this illumination.
the northern half of Aristarchus was "2x>" than the southern half of
the crater. There were two white patches of apron material near to the
crater Herodotus that were 50% of the brightness of the southern half
of Aristarchus. Furthermore the southern half of Aristarchus had a
circle - "dull patch on inner S wall with a bright point shining

refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP
in Macrobius. His report is as follows: "Blinked Macrobius with Wratten
Filters Blue 38A and Red 29. Macrobius became almost invisible through
the Blue 38A and essentially the same as in white light through the Red
29. The interior of the crater was completely in shadow. The only part
of the east wall that was visible was an apparent high point still in
the sun and seen as a bright point of light. This faded into darkness
before 13:56UT. No sign of any illumination of the east wall crater
interior or the interior of the west wall was seen during the
observation period. The outer west wall was a rough looking,
complicated mix of deep shadow and illuminated sunlit terrain." The
observer concluded that there was not a TLP - although he did get a
filter reaction, this may have been due to the different densities of
the filters? ALPO/BAA weight=2.

On 1989 Aug 20 at UT13:55 M. Lucas (Melbourne, Australia, naked eye)
witnessed a "pin-point flash" in the middle of the lower right quadrant
of the Full Moon. Foley suspects that this was in the Proclus region?
The Cameron 2006 catalog ID=374 and the weight=2. The ALPO/BAA

Messier A 1951 Oct 20 UT 00:00? Observed by Moore (England)
"Brilliant white circular patch in it. has seen it & Messier
blurred several times." NASA catalog weight=4 (good). NASA
catalog ID #545 Note that the date and time given are probably
wrong as the Sun is ~7deg below the local horizon at this time.
ALPO/BAA weight=1 to reflect this error.
Aristarchus 1957 Oct 13 UT 07:00?$ W.Haas, according to the 1978
NASA Catalog is supposed to have seen a bright spot of light --
"explosion" in this crater. Confirmation of activity
in Aristarchus - Three independent observations within 4 hours.
Cameron 1978 catalog weight=5 and TLP ID No.=676. Private
comunication with Haas shows that he recorded nothing unusual
on the 12th or 13th. Therefore an ALPO/BAA weight of 1 has
been given until this matter is cleared up.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3"
refractor) observed that the south floor of Aristarchus was wellow -
"almost gold, spilled over S wall on ray toward Herodotus". Cameron
comments that Bartlett often reported a yellow floor but not a spill of
the colour over to the external ray. Cameron also comments that
Louderback's refractor would refract more in blue light than in yellow,
therefore she did not think that it was due to chromatic aberation. The
Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=2.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3"
refractor) found that all of Mons Piton was "unusually dark". Points D,
C (E and S resp), usually brightest points, but this time were not
bright. "Whole mt was as dark as W wall usually is at this time. In
violet filter Piton disappeared completely, but was a little brighter
in red filter and points D & G showed. Color not seen by eye. No albedo
measured. Suggests red event." Cameron rules out chromatic aberation
from Louderback's refractor. The Cameron 2006 catalog ID=431 and the
weight=3. The ALPO/BAA weight=1.
Plato 1975 Jun 28/29 UT 23:00-01:20. Foley (Wilmington, UK, 12"
reflector, seeing, III, good clarity transparency). At 23:00,
00:30, and 01:15 blue was seen on the inner wall:floor southern
boundary, and red on the corresponding northern floor:wall
boundary. However by 01:20, blue was now on the S-NW floor:wall
boundary, and red on the NE-SE floor:wall boundary. Atmospheric
spectral dispersion existed in many regions, but did not change
like the colours in Plato. Similar appearance craters such as
Grimaldi, Schickard, and Riccioli, were checked for a similar
change in colour, but no change was noticed in these. ALPO/BAA
weight=1.
Stochard of Dublin, Ireland, saw naked eye at 10:30UT on

reflector, seeing, III, good clarity transparency). At 23:05,
blue was seen on the inner wall:floor southern boundary, and red
on the corresponding northern floor:wall boundary. However by
00:30, blue was now on the W floor:wall boundary, and red on the
E floor:wall boundary. Atmospheric spectral dispersion existed
in many regions, but did not change like the colours in Plato.
Similar appearance craters such as Grimaldi, Schickard, and
Riccioli, were checked for a similar change in colour, but no
change was noticed in these. ALPO/BAA weight=1.
On 1991 Dec 28 at UT 02:10 P. Moore (Selsey, UK) could see no detail on
the floor of Plato crater. This report needs to be read in context with
the comments by Cameron for A.C. Cook's observation of the floor of
Plato on 1992 Jan 18 - Cameron 2006 catalog ID=438.
On 1974 Jun 12 at UT0256 an unknown observer noted a dark blob on the
northern edge of the floor of Pitatus crater.
1837 Mar10 UT 13:46 (19:07 local time) T.G. Taylor (Madras,
India) whilst observing a 9th magnitude star being occulted,
noticed a 6th magnitude nebulous spot where Aristarchus
should be. Had never seen anything quite as bright as this on
previous occasions. ALPO/BAA weight=2.
On 1983 May 15 at UT20:30-21:05 P.W. Foley (Kent, UK, 12" reflector)

On 1987 May 03 at UT 19:00-19:30 H. Miles (Cornwall, UK, 5" refractor,
x30) found the Earthshine to be both pink and bright with prominent
features clearly visible. A "brilliant" star-like point was seen in
Aristarchus crater. There was another, albeit less bright spot near
Darney-Agatharides. Spots pesisted despite various tests. Foley also
confirmed that the Moon looked pink to him as well. The Cameron 2006

On 1991 Dec 09 at UT 22:50 D. Darling (Sun Praire, WI, USA, 3"
refractor, x36) witnessed a flash in Grimaldi crater. Cameron comments
that others had seen a flash there earlier, and there was a meteor
swarm. Fritschel (madison, WI, USA, naked eye observing) detected 3
flashes in Grimaldi and also at the western limb of the Moon. D. Weier
(Sun Praire, WI, USA, 3" refractor, x36) was also observing. The
Cameron 2006 catalog ID=436 and the weight=5. The ALPO/BAA weight=2.
On 1880 Nov 06 at UT 20:00 an unknown observer observed a TLP at an
unknown location on the Moon. The Cameron catalog has an entry for this
date and time but does not specify the location, the observer or what
was seen. The Cameron 1978 catalog ID=218 and the weight=0. The
ALPO/BAA weight=1.
On 1966 Apr 24 at 21:30UT R.Livsey (Scotland, 6" reflector at x275)
observed that Aristarchus was "fluorescent" in Earthshine. It is
uncertain whether the description of "fluorescent" should be involve
this observation being categorized as a TLP, however just for safety it
will be assigned an ALPO/BAA weight=1. This was a BAA Lunar Section
report.
On 1983 May 16 at UT20:35-22:10 P.W. Foley (Kent, UK) noted that
Aristarchus was dull in Earthshine (UT21:36-21:40). The floor was a
luminous rose/violet colour. The Cameron 2006 catalog ID=219 and the
weight=0. The ALPO/BAA weight=1.
On 1987 Mar 04 at UT 19:03-19:47 H. Miles (Cornwall, UK, 5" refractor,
x30, S=clear) found at 19:03 that Aristarchus was exceptionally bright
(even without blocking out the sunlit side of the Moon), being the most
easily seen crater on the Moon, and this was despite the sky not yet
being dark. The crater had faded by 19:20UT and at 19:47UT Earthshine
was no longer visible. CED brightness measurements were made and were
less than usual and the inside of the crater may have had a blue/gray
colour (unclear from the Cameron 2006 catalog description). The Cameron
2006 catalog ID=299 and the weight=2. The ALPO/BAA weight=2.
On 1981 Jun 07 at UT02:30-03:00 B. Hobdell (St Petersberg, FL, USA,
10" and 4" reflectors, seeing=I) at 02:30UT saw a flash from
Aristarchus and another one from Schroter's valley. By 02:45UT
Aristarchus was starting to be difficult to see and had occasionally a
bluish cast. By 03:00UT the crater could only barely be seen. This was
odd because visibility on the Earthlit side was really rather good. The
Cameron 2006 catalog ID=143 and weight=0. The ALPO/BAA weight=1.
On 1981 Jun 07 at UT02:30-03:00 B. Hobdell (St Peterberg, FL, USA, 10

1837Mar11 UT 15:27 (20:48 local time) T.G. Taylor (Madras,
India) whilst observing a star being occulted, noticed a
6th magnitude nebulous spot where Aristarchus should be. Had
never seen anything quite as bright as this on previous
occasions (except the day before). ALPO/BAA weight=2.
North shore of Mare Crisium 1915 Dec 11 UT 06:00? Observed by
Thomas (Glenorchy, Tasmania) "star-like pt. on N. shore of
mare. (Eimmart?) Particularly bright spot. Tho't it was
sunlight from rim of sm. crater." NASA catalog weight=0 NASA
catalog ID #358. ALPO/BAA weight=1.
On 1981 Jun 08 at UT01:48-02:45 B. Hobdell (St Petersberg, FL, USA, 10
and 4" reflectors) could hardly see Aristarchus crater, however at
01:48UT it brightened in blue for about 3 minutes. Then at 02:20UT
there was a bright flash, and by 02:25UT the crater was very bright,
but by 02:45UT it was no longer visible. Cameron 2006 catalog ID=144
and weight=0. The ALPO/BAA weight=1.
On 1983 May 17 at UT20:13-20:40 P. Madej (Huddersfield, UK, x38 and
x63) found that Aristarchus was normal in appearance, but at 20:19 a
blood red disk was seen as bright as a 6th magnitude star. The colour
did not vary but the brightness changed from 4 to 8 over a 1.5-3min
period, on the south west wall. Foley (Kent, UK, 12" reflector)observed
Aristarchus at 22:10 and noted that it had the same rose-violet colour
as had been seen by him a day earlier. The Cameron 2006 catalog ID=220
and the weight=0. The ALPO/BAA weight=3.
On 1983 May 17 Foley (Kent, UK, 12" reflector)observed
Aristarchus at 22:10 and noted that it had the same rose-violet colour
as had been seen by him a day earlier. The Cameron 2006 catalog ID=220
and the weight=0. The ALPO/BAA weight=2.
Daniell 1979 Apr 02 UT 21:45-22:14 Obseved by Madej (Huddersfield, UK,
158mm reflector, f/4.2, x36-110, seeing II-III) "Obscuration seen" BAA
Lunar Section Report. Cameron says that this was a bright white cloud
that covered three quarters of the crater. A yellow filter was used at
21:48, but the cloud was still white, albeit thinner (at x110). By
22:14UT the TLP was barely visible and again no colour seen. Buczynski
(Lancaster, UK, seeing = poor) saw spurious colour. Later (22:31-
22:46UT?) Mellor obtained some photos, but these revealed no colour.
The Cameron 1978 catalog ID=48 and the weight=3. The ALPO/BAA weight=2.
On 1983 Jan 19 at UT 18:00-19:00 G. Amery (Reading, UK) discovered that
Aristarchus could not be seen in Earthshine, this was odd because less
prominent features could be seen. Other observers (Moore and Foley)
confirmed the very low brightness of the crater. The Cameron 2006
catalog ID=197 and the weight=2. The ALPO/BAA weight=2.
On 1983 Jan 19 at UT 18:00-19:00 G.W. Amery (Reading, UK) found that
Messier was difficult to define. The Cameron 2006 catalog ID=197 and
the weight=2. The ALPO/BAA weight=1.
Linne 1867 Aug 06 UT 21:00? Observed by Buckingham (England?)
"Crater in darkness, he saw a "rising oval spot". Other obs.
saw it as a triang. Bold black spot pointing to earth, slowly
diffused white & drift of white on slope of pyramid. (indep.
confirmation?)" NASA catalog weight=5 and catalog ID #155.
ALPO/BAA weight=2.
Near Ross D (23E, 12N) 1964 May 18 UT 03:54-04:53 Observed by
Harris, Cross et al. (Whittler, CA, USA, 19" relector x720, 8"
reflector x322, S=G) "White gas obscuration. Moved 20mph,
decreased in extent. Phenom. repeated. Drawing." NASA catalog
weight=5. NASA catalog ID 811. ALPO/BAA weight=4.
White spot near Censorinus 1966 Dec 18 UT 23:40-23:46 Observed by Enie
(Pittsburgh, Pennsylvania, USA, 8" reflector x100, S=G) "Attention
drawn to pink color in this usually white patch. Brightened to a light
reddish tinge for 2 mins, then faded back to pink, then to white,
Sketch." NASA catalog weight=4 (high). NASA catalog ID #1002.
On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP
coordinator, Patrick Moore, to report a possible colour anomaly in
Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing
unusual. However by this time North was reporting that, the colour was
fading. Two other BAA members were alerted, but were clouded out. The
ALPO/BAA weight=3.
On 2001 Apr 29 at UT 20:50 R. Braga (Italy) reported that without any
filter, the brightness of the east wall of Torricelli B was halfway
Torricelli C (faintest) and Moltke (brightest). By insering a Wratten
25 red filter though, the crater was slightly more evident. However
using a blue Wratten 39A filter, the crater vanished completely, whilst
Toricelli C remained. The ALPO/BAA weight=3.
Webb (England, using a fluid achromat) saw brilliant minute spots and
streaks in Mare Crisium dotting its surface. This was seen near first
quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall
had all seen it this way at times. Cameron 1978 catalog iD=111 and
weight=3. ALPO/BAA weight=2.
Plato 1948 Apr 15 UT 20:00? Observed by Thorton (Northwitch, England,
9" reflector) "Brilliant orange-yellow flash 1 km inside E. rim
(similar to earlier #500 LTP flash in the dark)" NASA catalog weight=3
(average). NASA catalog ID #504.
