On 25 Jun 1993 at UT 23:30-23:52 Carlos Colesanti (Mairinque,
Brazil) obtained two CCD images of Julius Caesar crater and
noticed a brilliant fuzzy area on the rim of the crater. This
appeared in both images and resembled a fuzzy white blob. Note
that this is a REA-Brazil observation. ALPO/BAA weight=1.
Cameron (2006) ID=463.
On 1981 Feb 10 at UT21:46-21:49 P. Madej (Huddersfield, UK) found a 2nd
mag star-like point on the north east wall of Aristarchus crater. M.
Price (Camberley, UK) at 21:46 and 21:49. North (UK) detected flashes
from the central peak. Foley saw Aristarchus as a "translucent glow".
Moore, Pedler and Ratcliff could not find Aristarchus. Earlier though
Amery (Reading, UK) had found Aristarchus to be sharply defined.

Alphonsus 1990 Feb 03 UT 18:00-18:23 Observed by A.C. Cook
(Frimley, UK, CCD video camera, seeing III-IV). At 18:06 W and
SE dark floor patches, equally dark, but at 18:10 and 18:23 the
W dark patch was the darker of the two?. Between 18:06 and 18:23

On 1987 Mar 09 at UT20:00 M. Mobberley (Sussex, UK) obtained some video
of Mons Pico - apparently these show the mountain with a puzzling
appearance (not sure whether it was the observer who claimed this or
some one who analyzed the tape). The Cameron 2006 catalog ID=300 and

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.

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.

The ALPO/BAA weight=3.
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.
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.
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.
On 1989 Sep 12 at UT00:58-02:25 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x159, S=7/10) observed similar light conditions to 1989 Jul
15. At 02:00 he observed pink on the south west wall of Aristarchus
crater. At 01:24UT the Aristarchus ray was yellowish, however the
entire Moon had a grey-yellow tinge of colour. Chromatic aberation was
observed at 01:56UT. By comparison Gassendi was checked and had no
colour. At 02:10 the crater wall of Aristarchus was unusual and was
quite different in appearance to rims of other craters. The cameron
2006 catalog ID=375 and the weight=1. The ALPO/BAA weight=1.
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

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

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

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

On 1978 Sep 16 at UT19:30 R. McKin (Colchester, Essex, UK, 216mm
reflector and binoculars) observed that Aristarchus, in the lighter
region, during the lunar eclipse, was duller than usual but no less
conspicuous than expected. The Cameron 2006 catalog ID=38 and weight=5.
The ALPO/BAA weight=1.
On 1964 May 26 UT 04:10-04:35 Bartlett (Baltimore, MD, USA, S=5, T=5).
observed that Aristarchus had a strong blue-violet glow on the east
wall and EWBS, with a strong violet tinge on the nimbus. Crater was
hazy, could not focus it in red, green or blue light. The Cameron 1978
catalog ID= and weight=4. The ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 P. Moore, (Selsey, UK) and others found
that Aristarchus and Plato changed in brightness and colour during a
lunar eclipse. Aristarchus was especially bright during the lunar
eclipse. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT 18:46-21:42 P. Moore (Selsey, UK) and other

catalog ID=162 and weight=5. ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 Henderson, Sykes and Radley saw an
obscuration near Le Verrier - a completely circular halo with dark mare
showing through it for a duration of 15 minutes. This was during a
total eclipse of the Moon. Cameron 2006 catalog ID=162 and weight=5.
ALPO/BAA weight=3.
On 1982 Jan 09 at UT21:37 P. Moore (Selsey, UK) observed that Plato
underwent brightness and colour changes, during a total lunar eclipse.
At 20:07UT Madej observed a "slight anomaly in Plato". Cameron 2006
catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT 18:46-21:42 M.Mobberley (UK) observed that Schmidt
was very bright compared to its surroundings during a total lunar
eclipse. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 Bouron (UK?) observed that the west
limb, during a total lunar eclipse, had dark orange on it. Cameron

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
photograph. Cameron suggests eclipse geometry as an explanation. Thye

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
lunar eclipse. The cameron 1978 catalog ID=557 and weight=5. The
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
area. Coloured bands were also seen on the Moon.
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
catalog ID=126 and 127 and the weight=5. The ALPO/BAA weight=3.
On 1915 Mar 22 at UT 11:30-12:30 Jackson (France?) observed Aristarchus
during a total lunar eclipse: "Dur. totality there remained vis. to the
NW a red luminous pt. not much larger than Mars & of the same color".

On 2000 Jun 15 UT 20:37 C. Brook (Plymouth, UK, 60mm
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
attracted everyones attantion. It extended its radiance to adjecent
craters (e.g. Herodotus) all throughout totality. At the subsequent
eclipse in September 1895 it was seen to be inconspicuous. the Cameron

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.

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.
Plato 1975 Jun 29/30 UT 23:05-00:30. Foley (Wilmington, UK, 12"

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.

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.
Grimaldi 1998 Mar 22 UT05:15-06:00 S. Beaumont (Windermere, UK,
127mm rich field refractor, seeing III, transparency Good)
observed that the northern half of Grimaldi seemed much lighter
than the southern half. She comments that she has seen this
before in last quarter phases, but it was really quite marked
how lighter the northern half was on this occasion. The ALPO/BAA
weight=1.
Aristarchus 1976 Oct 18 UT 07:42 Observed by Bartlett (Baltimore, MD,
USA, 4.5" reflector and 3" refractor, S=3, T=5) "Inner E. wall 6 deg

On 1964 Jun 28 at UT 08:20-09:10 Schmidling, St Clair, and Platt
(Riverdale, New York, USA, 8" reflector, x256) observed in the
Aristarchus, Herodotus, Schroter's valley area: two red spot glows,
glimmer, looked like ruby gems. Cameron says that the date was
predicted by Greenacre and looked for. The Cameron 1978 catalog ID=817
and weight=5. The ALPO/BAA weight=4.
In about 557AD (Month, Day and UT unknown), Gregory of Tours

On 1989 Feb 09 at UT 19:00 Ashton (Stafford, UK, seeing=V) observed a
"green glow in the "peninsular region" of Cape La Place (south of poss.
Helicon A?) and brown on the Earthlit limb. Foley (Kent, UK, 12"
reflector) noticed a "pin point glow surrounded by blue-green halo"
through a blue filter, but not seen through a red filter. He also
suspected some brightness variations. He noted that Aristarchus was
barely seen and Copernicus was only a faint smudge, presumably because
of the bright limb? J. Cook (Frimley, UK) observed a white glow in the
Cape region (made up of pin points?) - no other places had a similar
effect. P. Moore (Selsey, UK, 12" reflector) reported that nothing
unsual was to be seen anywhere on the Moon. M. Cook (Frimley, UK) found
a "bright point source near the tip of LaPlace perhaps maupertius D (or
LaPlace D?)." This was seen in a blue filter but not through a red
filter - the limb was also seen as bright and the cape as a faint
patch. Holmes (Lancashire, UK, 30"? reflector or refractor?) although
commenting that Aristarchus was a bit dull, could not see the Sinus
Iridum glow, North (UK) could only detect the vague presence of
Earthshine throug his finder scope, but not in his telecope. The
Cameron 2006 catalog ID=349 and the weight=2. The ALPO/BAA weight=3.

On 1989 Feb 10 at UT 19:00? Edmonds (England) observed a "bright red
coppery" colour in the northwestern part of Proclus crater. He checked
and found that there was no colour elsewhere, though he still suspects
that the effect was spurious colour. Cameron comments that usually blue
is seen in the north and red in the south if due to spurious colour.
The Cameron 2006 catalog ID=350 and the weight=3. The ALPO/BAA
weight=2.
A faint white pinpoint flash seen and also in the same position
a whitish glow around the crater. No futher flashes seen after the
first one. From UT2117-2130 the glow was still visible but faded
making it more difficult to locate. When Foley observed he found
Aristarchus not very visible in Earthshine, despite Plato, Grimaldi,
and several other features being visible. Both observers used
12" reflectors. Cameron's 2006 catalog Extension ID=124 and
weight=0. ALPO/BAA weight=3.
On 1985 Apr 25 at UT 21:34-22:04 H. Miles (England) observed
Aristarchus within Earthshine. Foley (Kent, UK, 12" reflector) had
observed it one hour prior to Miles and found it to be both dull and
blue - with a bright patch west of the crater on Aristarchus Upsilon
Mountain. At 21:45UT 6 star-like flashes seen on the floor. They
occurred again a few minutes later and repeated at 22:04UT.By 21:45UT
the bright patch had gone though. Smith (England) had also apparently
seen the flashes and a further glow, albeit more north of the one seen
by Foley. Miles confirmed Smith's glow north of Aristarchus.
Peters did not see much, indeed found Aristarchus to be quite
faint (2130-2141). The Cameron 2006 catalog ID=264 and the
weight=3. The ALPO/BAA weight=2.
Curious lack of detail, but this may have been related to
the seeing. Of greater interest though was a dark blue
splodge where the crater should have been. Shadow seen through
this splodge, but no crater rim seen.
Almost certainly the following was spurious colour and not
a TLP. Proclus was found to be brighter than Censorinus.
Red was seen on the northern inner floor and blue on the
edge of the external north rim NNE-NW. The rim to the SW
could not be seen. ALPO/BAA weight=1.
On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a
10" reflector at 32-64x) noticed that Aristarchus was not
visible, although the Earthshine was very obvious. Foley (of
Kent, UK, and using 12" reflector) noticed that the crater was
only just visible but Plato could definitely be seen. Cameron's
2006 TLP extension catalog ID=125 and weight=0. ALPO/BAA

On 1789 Sep 26 at UT 03:30 Schroter (Lillienthal, Germany) observed
close beneath Mons Blanc at the west foot, in the dark, a small 5th
magnitude, speck of light. Its round shadow was sometimes black,
sometimes grey. Cameron suspects that this is the same as her TLP
report No. 50. the Cameron 1978 catalog ID=62 and weight=4. The
ALPO/BAA weight=3.
