Near Desseilgny in Mare Serenitatis (29E, 25N) 1971 Feb 01 UT 19:40-
20:15 Observed by Persson (Hvidore, Denmark, 2.5" refractor, x100, S=G)
"Obscur. (blurred & dark) starting between Plinius & Menelaus moving
towards Posidonius. Normal after 2 min. A little crater (white spot)
periodically disappeared for several secs regularly every few min.
There was haze above onlt this spot. A tiny crater SE of it was invis.
till 2015h then became clear & steady. Color was reddish-brown.
Drawing. (Apollo 14 watch)." NASA catalog weight=2 (low). NASA catalog
ID 1293.
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
ALPO/BAA weight=3.
On 1988 Feb 25 at UT20:00? P.W. Foley (Kent, UK, 12" reflector) found

On 1969 Mar 27 at UT 18:42-18:47 Ringsdore (England, 15"
reflector, x350), Moseley (Armagh, Northern Ireland) and P.
Moore (Selsey, UK) observed nothing unusual in Alphonsus at
18:40UT, but at 18:45UT Ringsdore saw a blurring. At 18:43UT
Mosely saw a reddush-orange patch and this was confirmed by
Moore. NNW of the central peak, Mosely got a blink, but Moore
did not because of too much stray light. The colour was like
Jupiter's red spot, but less pronounced. The Cameron 1978
catalog ID=1118 and weight=5. The ALPO/BAA weight=4.
Alphonsus 1966 Nov 22 UT 03:17-03:40 Observed by kelsey (Riverside, CA,

bright luminous ray near west (astronomical?) wall on floor of Plato.
Cameron suggests sunlight between peaks?. The Cameron 1978 catalog ID=
233 and weight=0. The ALPO/BAA weight=1.
Archimedes 1971 Aug 01 UT 22:00(?) (19:00 originally given
probably local time) Miranda (Plaui, Brazil, 4" refractor,
x80) observed two grooves going from east to west, broadening
towards the west, across Archimedes. A drawing was supplied.
Apparently this was the first time that this was ever seen.
Cameron suggests rays? and also says that in fact a similar
phenomenon reported before in neasrly the same position
(Apollo 15 watch?). The Cameron 1978 catalog ID=1303 and
weight=2. The ALPO/BAA weight=1.
On 1980 Jul 22 at UT20:08-21:50 G.North (Sussex, UK, 8" reflector, x144
and x207, seeing III-V and transparency fair) suspected an obscuration
on the north and north west wall. The effect came and went. May have
been due to seeing and image contrast? Cameron 2006 catalog ID=101 and
weight=1. ALPO/BAA weight=1.
On 1987 Oct 03 at UT 01:0?0-02:00 R. Manske (Brooklyn, WI, USA, 8"
reflector, x226) observed sunlight glinting of the walls in spectacular
display of colours. White (even gold) was seen at the centre, and blue
on the top most part of the rim. The white (or gold) band was thin in
comparison to other bands. The observer suspects that this effect was
terrestrial atmosphere related. Cameron 2006 catalog ID=307 and weight=
0. ALPO/BAA weight=1.
Ross D 1966 Nov 23 UT 04:50-05:02 Observed by Cross (Whittier,
CA, USA, 19" reflector, x250 & 2390, S=4-5 (sometimes 6), T=4,
excellent contrast) Activity level 5, eastern third of Ross D's
circumference possibly partly obscured. ALPO/BAA weight=1.
Plato 1998 Mar 08 UT 19:30-20:10 S. Beaumont (Windermere, UK,
30cm reflector, Meade 23A and 38A filters, seeing III,
transparency fairly good, some haze) observed a whitish misty
effect seen bordering the shadows of the SE rim. It appeared
intermittently and was not seen in the violet or red filters.
Observers wonders if it could have been an effect associated
with the Earth's atmosphere, which was unsteady with some haze.
However, other craters appeared normal. The ALPO/BAA weight=1.

On 1980 Jul 23 at UT22:00 G.W. Amery (Reading, UK, 8" reflector, x144
and x207, seeing=III-V and transparency=fair) found that the interior
shadow was a light grey. BAA TLP coordinator (Foley) suggests that this
was light reflecting from the illuminated walls? Cameron 2006 catalog
TLP ID=102 and weight=1. ALPO/BAA weight=2.
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,
York, UK, 30cm reflector, x220 and x350, seeing 3-4/5, and transparency
5/5) - observed from 22:00-23:25UT no colour seen, nor obsecuration,
all filters negative, despite seeing a lot of fine setail inside this
crater.
On 1987 Oct 04 at UT 02:20 D. Darling (sun Praire, WI, USA, 12.5"
reflector, x170, S=8, VG, T=5) obtained the brightest measurement he
had ever recorded on the northern rim of Proclus. Brightness 9 and
adjacent plain was of brightness 6.5. The Cameron 2006 catalog ID=308
and the weight=3. The ALPO/BAA weight=3.
Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon,
England) - observer noted that the east outside wall was bright in red
and normal in blue. Note that the Moon was 30 deg above the horizon at
the time of the observation. The crater returned to normal at 20:58.
Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D.
Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at
times) noticed a possible obscuration over the southern part of
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.
At 2209h blood red small area was seen. 1 h later the most westerly
(IAU?) of the peaks had become hazy white all other areas were sharp.

Moon 1967 Apr 22 UT 02:30 Observed by Dunlap et al. (Corralitos
Observatory, Organ Pass, NM, USA, 24" reflector) "UV excess as in #
1029. Gradient was 10# at term. to 25-30$ at subsolar pt. (153 deg
long)." NASA catalog weight=5 (very high). NASA catalog ID #1031.
On 1982 Dec 27 at UT 23:00 M. Price (Camberley, Surrey, UK, Seeing=III
and transparency=good) observed that Piazzi-Smyth was brighter than Mon
Piton at 23:00. Photographic atlas was checked to verify that this was
abnormal. The Cameron 2006 catalog ID=193 and weight=4. The ALPO/BAA
weight=2.
On 1980 Jul 24 at UT22:10-22:55 P. Moore (Selsey, UK, 15" reflector,
x360 and x400) found an area just south east of the central peak (and
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.
LeCroy Jr. and Sr. (Springfield, VA, 4.5" reflector, x75, x300, S=3, T=
4) observed the following in the Aristarchus and Herodotus region:
"Both were fused together as an oval & had a bluish cast on the E.rim.
In W#25 filter it was white. At 0100h albedo decreased from 10+ to 9.5
& more detail could be seen. Separation of the 2 craters began to be
seen at 0007h, details much brighter, incl. c.p. in Aris. @ 0110h main
brightness & blue tint shifted to N. rim. At 0116h the SW rim was
brightest & no color. At 0122h ray was brightest & no color. At 0122h

Seeing = good, altitude=20 deg) observed during an eclipse brilliant
points for 30 minutes in Ross. Cameron says that the date given

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.
In 1954 Jan 19 at UT 03:00 Porta (Mallorca, Baleares, Spain, 3"
refractor, x50) observed the following during a total lunar eclipse: "3
brilliant yellowish-white spots between Picard & Peirce. Phosphor.
light distinguished easily against gray-green background of mare.
Irreg., intermittent. Did not perceive them all dur. totality. Next day
had impression that all of area was less clear & lightly veiled.". The

Moving glows seen around the middle of the
disk during a lunar eclipse.
On 1888 Jan 28 ~UT 23:20 Dyer observed that in this fairly bright lunar
eclipse was a dark isosceles triangle, with the base to the north.
Other observers noted this effect.
On 1891 May 23 at 18:36-19:15 UT, Jackson of Sheffield, England, using
a 6" refractor, saw "1/2 hour before the end of a totl eclipse, a
region of the crater and just north of it, become conspicuous and
increased in brightness from then on" Cameron thinks this is just the
edge of the shadow and possibly normal. Cameron 1978 catalog ID=268 and
weight=0. ALPO/BAA weight=1.
In 1954 Jul 16 at UT 01:12 Chernov (Russia, 2" refractor, x33) observed
the following for Aristarchus: "Activity noted in it * in extension of
Moon's shadow on sky for 12 min during .17phase of ecl.(source gave
date as June 16, but ecl was July 16)". The Cameron 1978 catalog ID=566
and weight=1. The ALPO/BAA weight=1.
On 1963 Jul 06 at UT 23:00 (estimated) Chernov (Russia) observed in
Atlas 2 large spots that were not visible in penumbra after totality.

report ID=26 and weight=1. ALPO/BAA weight=1.
On 1978 Mar 24 UT16:10-17:45 Anderson (England?, 8" reflector, x55 and
x155). noticed a faint twinkling star like point in Dionyius - remained
constant but when changed to x155 at 16:25 the effect was at the limits
of visibilty. - suspected that this was due to the atmospheric
conditions. However this effect was not seen in Aristarchus. By 16:45
the twinkling area got brighter, but went back to normal at 17:45.

On 1980 Mar 04 at UT10:30-10:34 D. Darling (Sun Prairie, WI, USA,
12.5" reflector, x344) detected a pin-point light in the shadowed area
of Mare Crisium that varied in brightness then faded. Cameron 2006
catalog ID=84 and weight=0. ALPO/BAA weight=1.
On 1990 Jan 14 at UT 01:14-01:55 M.C. Cook (Frimley, UK, seeing=poor)
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
through it. (Bartlett's EWBS?)". The Cameron 2006 catalog ID=389 and
the weight=4. The ALPO/BAA weight=2.
Furnerius A 1983 Jan 02 UT 00:10 H. Hill (UK)
observed that this crater was piercingly bright,
which he thought was a bit unusual. ALPO/BAA weight=1.
Cleomedes 1991 Dec 23 UTC 22:50 Observed by Mizon (Colehill,
Dorset, UK, 8" f/6 reflector x216) "Oval or pear-shaped ashy
glow visible for 2 min, then vanished quite suddenly" - Ref.
personal communication received by BAA Lunar Section.
Plato 1938 May 17 UTC 08:00 Observed by Haas? (New Mexico?, USA,
12" reflector?) "Floor-least bit greenish (other colors on other
dates, e.g. Je 23, 7/22/37, & 7/15/38)." NASA catalog weight=3
(average). ALPO/BAA weight=2. NASA catalog ID #437.
Peirce A (Swift=IAU name?) 1937 Dec 23 UTC 22:00 Observed by Wilkins
(England, UK, 12.5" reflector) "Obscuration on floor if crater. Crater
invis. (similar to #394, 396)." NASA catalog weight=4 (high). NASA

On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9
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.
Macrobius 1898 Dec 31 UTC 20:00 Observed by Goodacre (Crouch End,
England, 12" reflector) "Interior nearly filled with shadow at sunset.
Inner E.wall very bright-a distinct penumbral fringe to black shad.

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.
Callipus 1952 Sep 09 UT 21:00-21:20 Observed by Moore (England)

On 1983 Jan 08 at UT01:00? P. Madej (Huddersfield, UK) noticed some
colour on Aristarchus. The Cameron 2006 catalog ID=196 and the weight=
2. The ALPO/BAA weight=1.
On 1983 May 15 at UT21:30-22:30 M.C. Cook and J.D. Cook (Frimley, UK)
could clearly see Aristarchus in Earthshine, whereas earlier that night
P.W. Foley (Kent, UK) could not see the crater although other features
were cisible. The Cameron 2006 catalog ID=215 and the weight=2. The
ALPO/BAA weight=1.
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 1991 Dec 09/10 at UT 23:53-00:12 D. Darling (Sun Praire, WI, USA,

On 2010 Dec 09 at UT 17:00 A. Heath (Long Eaton, UK) whilst
observing the Earthsine with 10x50 binoucluars, noticed some
coloured bands on the night side. The NW sector of Eartshine,
closest the limb was a normal dull brown, there was a whitish
fringe on this going from the N to the SE, followed by a thicker
bluish fringe. The rest of the Earthshine beyond, until reaching
the illuminated crescent was black. The two coloured fringes
curved slightly. Local temperature 38F and some broken cloud
present. Thickening cloud prevented further observations. The
observer suspects that it could have been caused by the weather
conditions, but could also have been due to a cataract starting
to form in his observing eye. This is unlikely to be a TLP due
to the above observer suggested reasons, and anyway it would
have to have been an unbelievably large phenomena to cover such
a large part of the Moon. However it is worth checking to see if
anybody else was observing at the time. ALPO/BAA weight=0.
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.
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

W.limb 1983 May 16 UT 22:00-23:00 R.Moseley (Coventry,UK, 6"
reflector, x60) observed a faint but extensive brightening of
the W.limb, perhaps a little stronger at PA=80-90 deg. No other
features seen in Earthshine although Aristarchus suspected.
ALPO/BAA weight=1.
North shore of Mare Crisium 1915 Dec 11 UT 06:00? Observed by

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 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.
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

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

ALPO/BAA weight=2.
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.
