1977 Apr 23 UT19:30-22:45 Foley (10.75" Newtonian and 4.5"
refractor, seeing II, transpaency excellent) saw som every large
variations in the brightness of Aristarchus whereas other
features in Earthshine remained stable. Aristarchus was seen to
be blue/violet. ALPO/BAA weight=2.
On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8"
reflector, x110 and x220) observed that Proclus and Piccolomini craters
both had a pink colour inside them. At a higher magnification of x220
Piccolomini was still pink and it was stronger on the central peak's
wesern side. The cameron 2006 catalog ID=407 and the weight=3. The
ALPO/BAA weight=1 as the Moon was not above the horizon at the date and UT given.
On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8"
reflector, x110, x220, seeing=good) observed that the north wall of
Proclus crater was the brightest part of the crater, indeed very
bright. Proclus and Picolomini had pink colours inside them. CED
brightness measurements were as follows: "Proc. at 100x 4.0, 4.0; at
200x 3.4, 3.4; Theop. 3.5, 3.9; 3.5; Herc. 2.5, 2.75; 3.5; Atlas 2.8,
2.5, 3.0; Posidonius 3.0." The Cameron 2006 catalog ID=407 and the
weight=3. The BAA/ALPO weight=1 as the Moon was not above
the horizon at the UT given.
On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8"
reflector, x110 and x220, seeing=good) observed that the west wall of
Theophilus crater was red (on terminator). However Posidonius was also
on the terminator and no colour was seen elsewhere along the
terminator, however Proclus and Piccolomini had pink interiors. At a
higher power of x220 a prismatic effect was seen on the terminator in
Theophilus and opther craters - "even on W rim of a crater due W of
Theoph.". CED measurements of Theophilus... 3.5, 3.9, 3.5. The Cameron
2006 catalog ID=407 and the weight=3. The ALPO/BAA weight=1
because the Moon was below the horizon at this time.
Censorinus 1959 Sep 08 UT 22:45-23:50 Observed by Jean Nicolini
(Brazil) "Much brighter than Proclus" NASA catalog weight=2.
NASA catalog ID #721. ALPO/BAA weight=2.
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.
Limb North? 1881 Jul 04 UT 00:30 Observed by Several observers

4" refractor) discovered that the central peak of Alphonsus crater was
very bright. The central peak was also brighter in red than in blue
light. However G. North (Herstmonceux, UK, 6" reflector, x135, seeing
V-III) and M. Cook (Frimley, UK, 4" reflcrctor, x10, seeing=III)
observed that the central peak was normal, however they did not use

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.
On 1882 May 27 ay UT 20:00 an unknown observer (10" reflector) saw a
bright luminous ray near west (astronomical?) wall on floor of Plato.
Cameron suggests sunlight between peaks?. The Cameron 1978 catalog ID=

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,

ALPO/BAA weight=3.
C. Brook of Plymouth UK, using a 4" refractor x216, noticed at UT 20:10
dark patches coming and going (in terms of visibility) on the floor of
Plato. Occasional views of the central cratelet (seen as a white spot)
were glimpsed. The dark patches seen lasted about 1-2 seconds before
fading out during each visibility cycle. Teneriff Mountains were
checked but no sign of seeing effects that might explain the dark floor
patches. By 20:26UT the dark patch effect was fading and by 20:31UT
floor detail was visible. Observations ceased at UT 20:34. Seeing
conditions were II and the Moon was at a high altitude. Other observers
were alerted but came on-line after the effect had finished. ALPO/BAA
weight=1.

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.
Moon 1967 Apr 21 UTC 02:30-09:30 Observed by Dunlap et al (Corralitos
Observatory, Organ PAss, NM, USA, 24" reflector + moonblink) "UV excess

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.
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.

The ALPO/BAA weight=3.
Observer noted a bright spot on the interior west wall that seemed
brighter than what they would have expected. unfortunately the precise
time of this observation was not recorded so the moon-rise and
midnight UT values are used to place a limit on the time of
observation. Images by Shaw taken at UT 1754, 18:45 and 23:13
do not exhibit the effect.
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

ALPO/BAA weight=2.
Gassendi 1966 May 01 UT 19:30-00:21 Observed by Sartory (UK,
8.5" reflector, x500, S=G), Moore, Moseley (Northern Ireland,
12.5" reflector x350, S=E) and by Corralitos Observatory
(Organ Pass, NM, USA, 24" reflector + moon blink) "Eng.

alerted by Sartory. Corralitos MB did not confirm. - but they
may not have been observing at the ame time?)." NASA catalog
weight=5. NASA catalog ID #932. ALPO/BAA weight=4.
On 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6"
reflector) took some photos (albeit out of focus) that showed a bright
spot on the west rim. Cameron comments that this spot was sharp
compared to the rest of the photograph, so was probably a photographic
artifact. The effect was not seen in the finder scope. The Cameron 2006
catalog ID=103 and weight=2. The ALPO/BAA weight=1.
M. Cook of Frimley, UK observed a brightening of the crater during
this observing session. The cameron 2006 extended catalog ID=346 and
weight=3. ALPO/BAA weight=2.
Aristarchus 1966 May 01 UT 21:55-22:45 Observed by Paterson,
Brown, Sartory, Ringsdore (England, 12" reflector x252 for the
former and 8.5"? reflector for the latter) "Eng. moon blink
system detected red spots with vis. by all but Ringsdore. Brown
saw intense white spot NW of crater wall" NASA catalog weight=5.
NASA catalog ID 933. ALPO/BAA weight=4.
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.
Herodotus 1965 Jun 11 UTC 21:35-21:40 Observed by Porta, Garau

On 1978 Mar 21 at UT 20:57 an Unknown observer observed a TLP in
Aristarchus crater. The details for this report are still being looked
up in the archives. In view of the uncertain details this TLP has been
given an ALPO/BAA weight of 1.
Aristarchus 1982 Jul 03/04 UTC 20:55-01:08 Observed by Foley (Kent, UK,
Seeing Antoniadi III) "Brightness variance" - CED 3.6-4.1-4.9. When the
crater was dark it had a slate-blue-grey interior. Moore found the
crater to be exceptionally bright and this was confirmed by J.D. Cook
(CED 3.8-4.1). The Cameron 2006 catalog ID=174 and weight=5. The
ALPO/BAA weight=3.
On 1982 Jul 03/04 at UT 20:45-01:08 J.D. Cook (Frimley,
Surrey, UK) found the Mare Frogoris area, north of Plato was
pink at 20:45UT. Saxton found flashes in Mare Frigoris and
near thye Alps. The Cameron 2006 catalog ID=174 and the

Aristarchus. 2024 Mar 22 UT 22:08. G.Vega (Argentina, Oro
Verde - 20cm f/5 Newtonian on an EQ5 Goto mount - two colour
cameras used: a Player One Ceres C & a Nikon D5100).
Colour images show a region of blueness from the W. rim of
Aristarchus and the NE of Herodotus (maybe also on the inner
SE rim of Herodotus?) i.e. generally SE of the Cobra's Head.
Blue colour is usually present on the rim of Aristarchus and
to the north - but I don't recall seeing such strong blue
colouration in this region before? No other craters exhibit
this blue colour. As the colour is present in two images,
taken with different cameras it looks genuine. Two other
colour images, at lower resolution, were taken from Oro Verde,
by W.Elias, at 23:06 and 23:18, but neither of these exhibit
this blue colour - but that maybe a resolution issue? ALPO/BAA
weight=3.0
On 1995 October 6 at UT 21:30 R. Lena (Rome, Italy - a UAI observer,
11.4cm reflector) saw 4 or 5 flashes from Herodotus crater. Light
intensities (mag?) ranged from 9 to 8 and they were brighter through a
red filter. There is no 2006 Cameron catalog entry for this observation
- it has come from the UAI web site. The ALPO/BAA weight=3.
On 1995 Oct 06/07 at UT 22:45-00:00 P. Mirteto (a UAI
observer, RI, Italy, 20cm reflector) observed some brightness

On 2009 Jan 09 at UT 20:00 P. Brierley (UK) took a CCD image of the
Aristarchus area - P.Grego upon examining this comments that he thinks
that Schiaparelli crater looked "muted in brightness -- it is normally
quite bright to look at". Though Grego comments that it might have
something to do with the image processing aplied to the image. The

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

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
area. Coloured bands were also seen on the Moon.
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

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.

illumination and still considers the Aug 20 appearance abnormal.
NASA weight=4. NASA catalog ID #545. ALPO/BAA weight=2.
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.
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.
Proclus 1973 Jan 21/22 UTC 23:57-00:25 Observed by Muller (located at
51.42N 8.75E) "Proclus much brighter than Cenorinus" 50mm refractor
used. Ref Hilbrecht & Kuveler (1984) Moon and Planets Vol 30 p53-61.
On 1979 Sep 09 at UT08:00-08:15 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x75 and photography used, seeing 4/10 and the Moon's
altitude was 45deg) photographed Romer crater and recorded two adjacent
bright cigar shaped objects - these were the same size as an
observation made in 1987. Darling believes that these are ridges.
Cameron comments that in LO-IV 192-3,2 a ridge is revealed on the
inside wall that matches the description. Cameron 2006 catalog ID=66
and weight=2. ALPO/BAA weight=1.
On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"?
reflector, seeing III) found that Aristarchus was very bright
and slightly blue. Cameron comments that Moore's eyesight is not
very blue sensitive. The Cameron 2006 catalog ID=175 and weight=
4. The ALPO/BAA weight=2.
On 1982 Jul 09 at UT01:05-01:25 P. Moore (Selsey, UK, 12.5" reflector,
seeing=III) found that Grimaldi A was the 2nd brightest feature on the
Moon, and that there was colour detected with a Moon blink device on
the floor of Grimaldi. The Cameron 2006 catalog ID=175 and the weight=
4. The ALPO/BAA weight=3.
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.
cast on it from W.wall. Seen best using high powers. (Firsoff & MBMW
give date as just 1895 but must be wrong-phase - see app.ref.)"
NASA catalog weight=4 and catalog ID #304. 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
weight=2.
Stochard of Dublin, Ireland, saw naked eye at 10:30UT on
1862 Nov 12 Aristarchus as extraordinarily bright as a bright
spot on the Moon. This was seen in daylight with the waning
crescent. Cameron 2006 extension catalog ID=6 and weight=3.
ALPO/BAA weight=2.
Ptolemaeus 1825 UT 23:45 Observed by Schwabe (Germany?) "Bright spot"
NASA catalog weight=4 (high). NASA catalog ID #108. ALPO/BAA weight=3.
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.
On 1916 Jan 27 at 22:00? Markov (Russia) noticed that a light sector
was visible at the bottom of Plato, in shadow, and contained 3 bright
spots, reminiscent of phfescent bodies. The Cmaeron 1978 catalog ID=362
and weight=3. The ALPO/BAA weight=3.
On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52"
reflector) observed that central craterlet in Plato was
unusually bright and shows up as a bright white spot on his
sketch - though this might have been artistic license in his
sketch. His written notes refer to the unusual lack of a rim
(especially the northern part) to this craterlet.
The ALPO/BAA weight=2.
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.
On 1979 Sep 16 at UT 08:00-09:00 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x62-x97, clear, but Moon at low altitude) detected
four new features that he had not seen before in Earthsine in
comparison with what he saw on 16 Jul 1979, this time in the southern
part of the Moon. pin-point flashes were seen within these bluish
areas. Each time a flash occurred the gas clouds brightened (sometimes
by 6x) for a few seconds. Cameron thinks that these are related to
moving clouds on the Earth's limb e.g. mackeral sky. Cameron 2006
catalog ID=69 and weight=1. ALPO/BAA weight=1.
Briggs A 1980 Feb 11 UT 06:30-07:00 Observed bt Butler_FC
(Brixton, UK, 22cm Newtonian reflector, x64, x104, seeing IV).
Found Briggs A to be brownish in colour at x64, however the
colour vanished at 06:55 when x104 was used. Switching back to
x64 the colour was still there but fainter. The colour fade may
have been due to day light glare encroaching? Could not see this
effect anywhere else on the Moon but did detect what he regarded
as a permanent coloured spot (yellow) between Cruger and
Grimaldi. ALPO/BAA weight=1.
On 1824 Jan 27 at UT03:00 Gobel (Koburg, Germany) observed a reddish
colour in Aristarchus crater. The Cameron 1978 catalog ID=98 and the
weight=4. The ALPO/BAA weight=3.
