Proclus 1967 Apr 18 UTC 18:40-18:45 Observed by Farrant (Cambridge,
England, 8" reflector x175) "Crater appeared quite dark, even bright
ring was subdued & seemed thicker than normal. Drawing." NASA catalog
weight=3 (average). NASA catalog ID #1028. ALPO/BAA weight=1.
Linne 1868 Jul 28 UT 20:00? Observed by Tacchini (Palermo, Italy)
"Shadow not so marked-had a light penumbra, indicated a feeble cavity.
Other craters had a black shad. On 29th appeared completely white.
Crater normal on 26th. (letter to Madler Sep. 16, 1868)." NASA
catalog weight=4 (high). NASA catalog ID #159.
A region of the Mare Imbrium was extremely bright, giving
a reading of 8 out of 10 on the Elger scale. Cameron notes
that from photos of the Full Moon, the area appears to
normally be the brightness of Archimedes floor i.e. 3.5 out
of 10 on the Elger scale. Atmospheric seeing was excellent
and the observer could see a lot of fine detail with their
2.4" and 3" refractors. Cameron 2006 catalog extension ID=62
and weight=3.
M.C. Cook (Frimley, UK) got an abnormally low brightness reading for
Proclus, despite nearby Censorinus being normal. Crater Extinction
Device used. The Cameron 2006 Extension catalog ID was 163 and the
weight was 3. The ALPO/BAA weight was 2 too.
On 1989 Feb 16 at UT02:46-03:01 D. Darling (Sun Praire, WI, USA, 3"
refractor, x140, seeing=6/10) found that the brightness of the rim of
Proclus was 9.0 (normal?). The Cameron 2006 catalog ID=354 and the
weight=0. The ALPO/BAA weight=1.
Gassendi 1977 May 28/29 UT 20:45-21:15 Observed by D. Sims
(Dawlish, Devon, UK) saw a hazy area on the south east floor
that was normal in red and white light but darker in blue.
This was partly confirmed by J-H Robinson (Devon, England, 10"
reflector) 21:24-23:12 who saw the south east floor of
Gassendi to have a loss of detail - but no colour seen,
although at 21:57-21:58 it was slightly brighter in red than
in blue briefly. P. Doherty (22:45-23:15) did not see anything
ususual. D. Jewitt (22:22-22:55) did not reveal anything
ususual, apart from spurious colour. The Cameron 1978 catalog
ID=3 and ID=1463. The ALPO/BAA weight=3.
Plato 1982 Jun 02 UT 22:00. Mobberley could not see the
central craterlet on the floor of Plato tonight. Foley notes
that he could only just see the central craterlet on nights of
2-5th Jun and it was of reduced in brightness from normal.
North reported that the floor seemed nearly black, but
brighter in a green filter (x144 magnification used). All
three observers compared the Plato area to other areas for
reference. All the above seems normal, apart from the floor
being brighter in the green filter. Cameron 2006 extension
catalog ID 170 and weight=5. BAA/ALPO weight=1.
On 1989 Feb 17 at UT00:55 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x248) found that the brightness of the rim of
Proclus was 9.0, the north west wall to be 9.5, the west wall
to be 5.2, and the east wall 8.2 (normal?). The Cameron 2006
catalog ID=355 and the weight=1. The ALPO/BAA weight=2.
On 1990 Jan 07 at UT 20:20-20:58 G.North (Herstmonceux, UK) thought
that he detected dullness in Torricelli B crater - Cameron comments
that this cannot be shadow). The Cameron 2006 catalog ID=386 and the
weight=3. ALPO\/BAA weight=2.
Observed by Haas (Las Cruces, NM, USA) "Temporary greyness seen in
interior shadow." ALPO/BAA weight=3.
Deslandre - 1965 May 12 at UT 19:10 E. Penzel
(Rodewisch, East Germany) was taking a sequence of images
during the impact of the Soviet Lunik 5 (upper stage of the
carier rocket?). He detected a tens of km scale elongated
cloud after the impact over a duration of 9.5 minutes. This
was near to Deslandre crater. However there are differences
between the images elsewhere on the Moon, possibly due to
different exposures or some other effects and it is not 100%
sure that what he detected was impact debris/cloud?. The
ALPO/BAA weight=1.
On 1933 Oct 01 at UT 03:00 Rawstron (USA, 4" refractor, x330) observed
the following in Mons Pico B: "Haze -- much narrower & elongated than
on Sep. 1". The Cameron 1978 catalog ID=407 and weight=3. The ALPO/BAA
weight=2.
On 1955 Oct 28 at UT00:00? Kozyrev (Crimea, Soviet Union, 50"
reflector) detected in Aristarchus Fraunhofer lines in UV spectra that
were much narrower than in the solar spectrum. This indicated
luminescent glow which overlapped contour(?) lines. Greatest after Full
Moon, but fluctuated monthly with no indication of solar activity
effect. The Cameron 1978 catalog ID=621 and the weight=5. The ALPO/BAA
weight=5.
On 2003 May 13 at UT06:40-07:26 W. Haas (Las Cruces, NM, USA, 12.5"
reflector, x321 and x202, S=2, T=3.5) suspected (06:40-06:55UT) that he
saw an oval bright feature (intensity 5.5) near the centre of the floor
of Herodotus crater indenting into the shadow - however the seeing was
none too good, so it is more of a suspicion than a definite sighting.
At 07:14-07:26UT he re-examined the region (x202 and x321, S=1-2 and T=
3.5) and had better glimpses that conformed his initial suspicions of
there being an oval indentation bright spot (now intensity 6) into the
shadow in the centre of the floor. Of course Herodotus does not have a
central peak! There was also a very bright spot on the NW> sunlit rim
of Herodotus crater. The ALPO/BAA weight=2.
On 1955 Oct 28 at UT 00:06 W. Taylor saw a naked eye flash on the Moon
in the north east area, on the edge of Mare Vaporum. The flash was
intense and radiated to a large area. The duration was 1/4 seconds.
On 1965 May 12 at UT 22:20 H. Miles (UK) found a possible
obscuration in Bailly crater. Most of the region was as sharp as
normal, but the central area was greyish and blurred. Although
the observer concerned considered themselves a non-experienced
observer, another BAA Lunar Section observer saw the same
effect. ALPO/BAA weight=2.
Aristarchus Area 2004 Nov 22 UT 04:58-05:49 Observed by Gray
(Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5,
x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red
25. The illuminated west crater wall stood out brilliantly in blue
light, much more so than in white light. This was true also of
Aristarchus. Red light did not increase contrasts in Herodotus any more
than they were in white light. Shadows in Herodotus appeared as black
as the night west of the terminator and remained that way throughout
the observing period. No TLP seen in Herodotus tonight. A possible TLP
was seen to the west of Herodotus near the terminus of Schroters
Valley. It was noted at the beginning of the observing period that
there were four very bright spots of light, one near the end of
Schroters Valley, the other three grouped together a little farther
north. Although not far from the terminator they were definitely east
of it. It was noted that all of them nearly vanished in the Blue 38A
filter while Aristarchus and the rim of Herodotus gleamed brilliantly.
At 5:19UT it was noted that the most brilliant of the four lights, the
one near the terminus of Schroters Valley, had faded almost to
invisibility in white light. When first seen it had been brighter than
Aristarchus. It remained very dim after this through the remainder of
the observing period, and was unchanged at 7:35-7:49UT when I again
examined the area. The other three bright spots remained brilliant and
unchanged."
Herodotus 1956 Nov 15 UT 01:05-01:30 Observed by Bartlett
(Baltimore, MD, USA, 3.5" reflector x100) "Pseudo c.p. clearly
seen est. I=5.5, wratten filters showed it neutral to green,

Farrant (Cambridge, England, 8" reflector, x160), Corralitos
Observatory (Organ Pass, NM, USA, 24" reflector with
Moonblink) "On exterior wall of Aris., 3 pts. in Cobra Head &
banks of valley were star-like & glowing; & Herod. were red.
Farrant could not bring hill N. of Herod. into focus. He says
color was deep red-orange & steady for 3 min. Started at
1915h (1916-1925h seeing was too bad) (indep. confirm.).
Suspected next nite but bad seeing. Not confirmed by
Corralitos MB." NASA catalog weight=5. NASA catalog ID #1030.

Herodotus 1966 Nov 24 UT 21:50 H.Hill (UK, 7.25" reflector,
x240), seeing 4-6/10, transparancy 4/5) sketched a central white
diffuse patch inside the floor of the crater, with a size of
about 1/7th the diameter of the crater. The eastern edge of the
white patch was encroached by the shadow of the eastern rim.
ALPO/BAA weight=3.
Proclus 1972 Dec 17 UTC 18:30 Observed by Farrant (Cambridge, England,
8.5" reflector) "Crater appeared very bright (Apollo 17 Watch)." NASA
catalog weight=2 (low). NASA catalog ID #1359.
Plato 1973 Aug 10 UT 22:45 observed by Robinson (Devon, UK).
Observer noticed that the lighter areas on the floor were more
distinct in red than in the blue filter. ALPO/BAA weight=1.
Blanco, J. Vidal, of Gijon, Spain (3" refractor x72)
noticed an unfamiliar very bright center near to Encke.
Cameron suspects that this was Encke B crater
on the basis that it is a prominent small crater
near to Encke. Cameron 2006 catalog extension ID=410
and weight=2. ALPO/BAA weight=1.
In 1949 Nov 03 UT 01:06 J.Bartlett (3.5" refractor, x100) noted that
the floor of Herodotus was very dark, the east wall was very bright,
and the floor contained a central bright peak. The BAA/ALPO weight=3.
Aristillus 1972 Dec 17 UTC 21:50-22:20 observed by Berger (51.5N, 9E,
60mm refractor, T=2, S=3) "Diffuse bright cloud in the NE corner of the
crater" - Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-
61.
Amery (Reading, England) saw blue in Aristarchus but a photograph did
not show the colour. Foley thinks this was spurious colour. Cameron
2006 extension catalog ID=27. ALPO/BAA weight=1.
Promotorium Laplace: 1978 Apr 20 UT19:30-22:35 Peter Foley
observed a tiny yellow-brown region close the tip of the cape,
north east of the precipitous west edge, in the face of the
north facing slope. The area concerned was diffuse and varied
in density despite the surroundings not varying. Foley notcied
no colour elsewhere on the Moon, though Amery thought that he
saw some in Aristarchus, but Foley thinks this was spurious.

On 1983 Dec 17 at UT 17:25-19:20 Moseley (Covington, England, UK, x120
and x240, seeing=III and spurious colour present) found that the inside
of Aristarchus crater was dull and slightly blue. Suspected the colour
to be spurious: at 19:20 at x240 the colour was pink but at x120 there
was no colour. Cameron 2006 catalof ID=234 and weight=3. ALPO/BAA
weight=2.
On 1987 Mar 13 at UT02:00-03:00 De Groof (Belgium, 8" reflector x150,
seeing=clear) noted that the north west part of Aristarchus had a blood
red shimmering filling the whole crater. A video by Mobberley some 18
hours later, shows variation in Aristarchus. Cameron 2006 catalog ID=
301 and weight=5. ALPO/BAA weight=3.
Vallis Schroteri 1991 Aug 23 UT 02:19-02:49. Flashing spot at
end of SV fluctuated. Herzog, Darling & Weier confirmed spot
but not fluctuation. Spot brighter in red than blue, but Cobra
Head was bright in blue. No other region was abnormal.
Aristarchus-Cobra Head, 1967 Nov 15 UT 05:40-06:00 Observed by Cross,
Tombaugh (Las Cruces, NM, 12" reflector x800) and Harris (Tucson, AZ),
and Dunlap (Organ Pass, NM, 24" reflector with Moonblink). "Obs.
reddish color N. & E. of Aris. & more intense color nr. E.(IAU?) rim of

between 0543-0549h in 3 spectral bands (blue, yellow, red, & integ.
light). No change dur. obs. per. but spot got smaller at moments of
good seeing. Isodensitometry of photos. At Corralitos 0152-0155 on 24-
in image intensifier & filter sys. photoos at 0320-0330h. Harris at
Tucson got spectra. Neither of latter 2 show anything unusual. Its
edges were nebulous even at best seeing. Size @ that of Cobra's Head."
NASA catalog weight=5 (very good). NASA catalog ID #1053.
Peter Foley (Kent, UK, 8" reflector, seeing=II) noticed that
the floor beneath the north wall, and the area over the north
wall were indistinct (almost out of focus). Despite looking
elsewhere in the crater and surrounds, no other blurring
(obscuration of detail) could be seen, indeed everywhere else
was sharp and detailed. Foley tried several eyepieces but this
made no difference. He used a crater extinction device but
found no variations in brightness. There was a slight
darkening when he used a red filter in the Moon Blink device.
The obscuration effect weakened between UT20:56 and 21:10,
was difficult to see at 21:13 and had finished by 00:15.
Patrick Moore (12" reflector, Dublin, Ireland) saw nothing
unusual when he started observing at UT 22:00. Cameron says
"Photos marked at location of phenomenon". Cameron 2006
extension catalog ID=37 and weight=5. ALPO/BAA weight=3.
Aristarchus normal in red and blue filters however the
Cobra Head part of Schroter's Valley was brighter in blue.
Indeed it was very dull in red - Louderback says that this
was not surprising as the whole areas around Aristarchus is
brighter in blue. Louderback is an experienced observer
of the Aristarchus area of more than 10 years. Cameron 2006
extended catalogID=63 and weight=1. ALPO/BAA weight=1.
Plato 1873 Apr 10 UTC 21:00? Observed by Schmidt (Athens, Greece, 6"
refractor) "Under high sun, 2 faint clouds in E. part of crater."
The area west of Helicon not visible despite the area being
fairly bright at Full Moon time. This area was a very bright
patch one night. Cameron notes: comensurability of Full Moon &
Perigee. Cameron 2006 catalog extension ID=64 and weight=3.

On 1982 Jun 05 at 22:00? UT, Chapman (UK, using a 12" reflector), again
using a x2 yellow filter, noticed that the central craterlet
detectabilty changed such that sometimes it was visible and sometimes
not. Foley (Kent, UK)noticed that the central craterlet could only just
be seen between June 2 to June 5 and was much less discernable than
during the previous lunation. No CED brightness measurements made. The
floor of Plato was noted to be very dark though. Cameron 2006 catalog
ID=172 and weight=4. ALPO/BAA weight=2.
Aristarchus 1965 May 15 UTC 01:40-02:15 Observed by Weresuik, McClench,
Johnson (Pt. Tobacco, MD, USA, 16" reflector x240, S=F, T=G) and Delano
(Massachusetts, USA, 12" reflector). "Crater had color(red?) detected
by Trident MB & photos were obtained. There were pulsations. Delano saw
E. wall of crater unusually bright (confirm. if at same time)." NASA

Newtonian (dobsonian), 9mm Plossl eyepiece, Samsung A33 mobile
phone camera, 36 sec AVI file at 30fps, seeing probably
average-good). Noticed a blue tinge on northern rim of the
crater. This is probably normal, but we are flagging this up
as a weight 1 TLP, in order to obtain some repeat illumination
observations and confirm that the strength of the blueness is
normal.
Madler 2005 Oct 17 UT 04:14-05:28 Observed by Robin Gray (Winnemucca,
NV, USA, 152mm refractor, x228, x343, S=5-8 and T=5-6) "Very bright

On 1898 Jan 08 at UT 00:00-01:00 Chrevremont (France?) notcied that
during a lunar eclipse, the mid-eclipse shadow was so dark that details
of the surface disappeared, all except for the Tycho SSW ray . Cameron
comments that it is unsual for that ray to remain when usually the ones
towards Kepler and Aristarchus are the ones to stand out? The Cameron

On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor,
seeing=II) found that the inner bands of Aristarchus were hard to see,
this was odd because the seeing conditions were good and he usually
sees them? However he did not believe that there was any obscuration
going on. The Cameron 2006 catalog ID=37 and weight=0. The ALPO/BAA

On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50)
observed a bright flash (~0.3 sec duration) near to Copernicus (20W,
9N) with rays to the south east whilst he looked through a finder
scope. Moore, who studied the drawing, suggests that the area of the
flash was near Copernicus. However Cameron says this cannot be the case

the north of Aristarchus, varying in sharpness/diffuseness. The crater
rim in this region could not be descerned. Eleswhere the crater rim was
normal as too were other features. When a Moon blink device was used,
no colour blink was detected, however through the blue filter the
suspected area was bright and the crater rim indistinct. Whereas
through the red filter the area looked perfectly normal. At 22:30UT the

(Winnemucca, NV, USA, 152mm F9 refractor Seeing 6-7, Transparency 6
305x) "Blinked Proclus with Wratten Red 25 and Blue 38A filters.
Features seen through the red filter were basically seen with the same
degree of clarity as in white light, in the case of sunlit walls, maybe
a little bit better in the red. With the Blue 38A filter only the
brightest part of the crater walls (north end) was visible-the rest of
Proclus was dark shadow. At 3:07UT I compared the brightest parts of
Proclus with Censorinus and Dionysius. The brightest parts of Proclus
and Dionysius were comparable. Censorinus was much less bright than
either of the above craters-the halo and crater were much faded over
its usual brilliant appearance. Both Censorinus and Censorinus A
were visible as distinct craters at 114x. The black shadow covering the
east 40% of Proclus last night had broken up into three patches
separated from each other by lighter bands. These were confined to
the east crater wall. Only the central patch was black, the other two
were considerably lighter. Running along the southwest edge of the
crater floor of the crater floor appeared to be a hill to the north
of which was a less elevated plateau. As the observing period
progressed part of the brilliantly illuminated north crater wall
developed a darker area which gradually became more prominent. As
the sun is getting higher I would expect shadows and dark areas to
diminish-what was happening here is unknown. However, this is not an
unusual event for this part of Proclus". The ALPO/BAA weight=2.

1987 Feb 06 UTC 02:35 Observed by Darling (Sun Praire, Wisconsin, USA,
12.5" Newtonian x342) "I was using a 12.5 f5 Newtonian reflector with a
9mm eyepiece and 2x Barlow with no filters. I had been observing other
features on the Moon when I had panned to the area where the sunrise
was taking place on Mount Piton. The mountain peak looked like a
shimmering block of ice with a phosphorescence luminescence cloud
around the peak. What was really interesting was the shaft of light
streaming across the Lunar Maria that appeared like a cone and it came
to a point near Mount Piton. The Mountain had the appearance of mother
of pearl and the luster or glow that surround the peak only lasted
about 20 minutes." The Cameron 2006 catalog ID=296 and gthe weight=4.

On 1969 Nov 18 at UT 00:30-02:30 W. Cameron (Greenbelt, MD, USA, 12"
reflector, x80 and x320) using a low power eyepiece, observed that
bright craters (but not all of them) "glittered like diamonds". These
craters were several on the terminator, Proclus, Censorinus, Manillius,
Menelaus and Dionysius. The glitter effect was on the west wall crest
-- like stars. Higher power revealed these areas to be bright but not
star-like (nor glittering). The Cameron 1978 catalog ID=1212 and the

Mons la Hire 1972 Nov 15 UT 09:45-10:18 M.Geisel (Brisbane,
Australia, 12.5" f/8 reflector, x90) discovered the TLP, P.
Anderson (9.5" reflector) independently confirmed that the TLP
had an effect in his Moon Blink device - but the effect
(suspected that the blink was caused by the extreme nrightness
of the mountain?) was weak and thought it not worth further
investigation. Photographs taken by Anderson. Geisel believes
the effect to be real and states that the area remained sharp

Observed by G.H. Johnstone of Albuquerque, NM, USA on 1954 Nov 05 UT
20:00 (according to Cameron), but 02:00-04:00 according to the
original observation and at colongitudes 34.7 to 35.7 deg. 4"
reflector, x150 used. The obsewrver reported that the western part
(about 1/3rd of the interior) was pitch black with shadow. However
there was a zone about as wide, or perhaps only a fourth of the total
width that was distinctly a lighter bluish shade, almost like twilight.
The shadows of the peaks on the western edge of the rim were clearly
seen crossing this bluish shadowed area. Then this area ended sharply,
and the farside was bathed in light from the rising sun. The shadows of
the peak were sharply defined across the twilight zone, and the edge of
the pitch black shadow was easily defined but not as sharp as the
darker shadows crossing the the blue twilight zone. The observer
checked other craters but did not see this condition in any of them -
they all had the abrupt division between black and white that we would
normally expect to see. Cameron 1978 catalog ID=579 and weight=2.

P. Moore at 21:10 found the southern wall (and ontothe southern floor)
of the crater to be indistinct. Elsewhere in the crater everything was
sharp. The effect was still seen at 21:42UT, but less strong. A check
was made for colour with aq Moonblink device, but none was seen. There
was still a trace of this effect at 21:44UT, although detail was now
becoming visible. By 21:48UT vertical streaks were seen crossing
the floor from the obscuration area and these were more visible in the
red filter and not in the blue. Cameron comments that undefined patches
on the floor of Plato are not normal. By 21:55UT some craterlets on the
floor started to become visible and the TLP for Moore ended by UT22:23.
P.Foley was alerted by Moore and saw a "amssive dense obsecuration
on the south wall, south floor and south outer glacis to the Mare".
Foley noted that by 21:50UT the effect was fading and finished by
22:03UT. Foley reported an orange translucent haze covering half of the
floor, but floor craterlets could be seen on and off - however his
atmospheric seeing conditions were IV. At 22:00 UT Foley reported the
floor close to the north wall to be "milky or misty". No detail was
visible at 21:15UT and variability in the floor continued until
23:10UT. Hedly-Robinson was aleted at 21:35UT and found no difference
between red and blue views of the area, however he did find that the
south rim was indistinct although this effect had lessened by 22:00 UT
and was normal by 22:17UT. M. Mobberly saw a white spot on the floor at
21:20 UT, whereas he normally would have expected to see craterlets.
Mobberly was alerted at 21:40 UT and took some colour photos. He also
made sketches that showed variability in the floor and dark lines and
patches in the north west corner. However the altitude of the Moon was
low. Cameron mentions that two of the photos show loss of detail at the
south wall and beyond.and also a change in the floor markings.The north
wall at 21:50UT was strangely reddish (didn't think this was spurious
colour). The rest of the wall was sharp at 22:20UT through a yellow
filter. Large bright patch in the centre and rest of the floor was
apparently of the same shading as Mare Imbrium. The above notes are
based upon the Cameron 2006 catalog extension TLP ID 145 and weight=4.
