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.
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.
Proclus 1955 Aug 03 UTC 04:13-04:40 Observed by Bartlett (Baltimore,
MD, USA, 5" reflector, x180, S=5, T=5) "Floor blackish 2 intensity but
in green filter assumed a distinctly mottled or flocculent appearance
-- seen only in green. Neither blue nor red had any effect, but on
previous eve. green light had not produced such an appearance." NASA
catalog weight=4 (good). NASA catalog ID #602. The ALPO/BAA weight=3.
Aristarchus 1976 Jun 12 UT 05:21 Observed by Bartlett (Baltimore. MD.
USA, 4.5" reflector, 40-225x, S=5, T=3, "Deep viol. tinge in N. 1/2 of
nimbus. Faint blue-viol. radiance (gas ?) on E. - NE wall along crest.

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 2000 Jun 16 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.
F. Graham took some photos of the Cobras Head and found a blue cloud
about 50 km in diameter and scattering light - Cameron says that
this indicates high density. Darling found the Cobra's Head obscure and
variable "clear and bright to diffused". Cameron was alerted observed
(02:40UT) variations with periods of approximately 30 seconds, and
thought that she could see a red tinge on the east rim of Aristarchus -
checks elsewhere found no other colours. Darling found that a blue
filter enhanced the effect and a red filter made it disappear. There
was a blink at 02:55UT but no blink in the Cobra's Head, which looked
fuzzy and lacking in detail. The effect was confirmed by Weier, who
also saw two dark spots in the Cobra Head in blue but not in red light.
The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall
7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south
wall 7.0, East wall 8.0, and the central peak 10.0. Observer details
were as follows: Darling (Sun Praire, WI, USA, 12.5" reflector, x159,
S=9/10). D. Weier (Sun Praire, WI, USA, 12.5" reflector, x159, S=

less (bright?) than Torricelli B's blueness. Other craters checked but
were not showing any blue colour. The Cameron 2006 catalog ID=198 and
weight=5. The ALPO/BAA weight=3.

observed the whole region of Aristarchus, Herodotus and Shroter's
Valley all to have a brightness of 3 and all blue and impossible to
focus on (he had never seen it like this before). Also the interior of
Aristarchus was invisible. Brightness measurement taken and a sketch
was made. The Cameron 2006 catalog ID=222 and the weight=3. The
ALPO/BAA weight=2.
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
if the flash was in darkness as mentioned in the BAA Lunar Section
circular. She comments that it might have been a meteor? The Cameron
2005 catalog ID=28 and weight=1. 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

BAA Lunar Section report.
Aristarchus 2004 Dec 02 UT 03:00 Observed bt Michael Amato (West Haven,
CT, USA, 127mm Maksutov, x123) "The brightness variation (as seen by
Brook earlier) was very apparent. One thing never seen before by Amato
was a thin short bright ray that extended out in the opposite direction
as Aristarchus bright ray". The higher the Moon climbed in the sky the
more obvious this short thin bright ray became. An ALPO report.
Plato 1975 Jun 29/30 UT 23:05-00:30. Foley (Wilmington, UK, 12"
reflector, seeing, III, good clarity transparency). At 23:05,
blue was seen on the inner wall:floor southern boundary, and red
on the corresponding northern floor:wall boundary. However by
00:30, blue was now on the W floor:wall boundary, and red on the
E floor:wall boundary. Atmospheric spectral dispersion existed
in many regions, but did not change like the colours in Plato.
Similar appearance craters such as Grimaldi, Schickard, and
Riccioli, were checked for a similar change in colour, but no

G Johnson of Swanton, MD, USA used a 2" refractor at f/12.
Aristachus revealed as a red spot on a photo of the Moon. This
was similar to another photo obtained on 1988 Apr 21st. Frame (with 3
exposures present)reveals a dim star like point near Campanus on
exposure 1. Expsoure 2 shows it a little east on the Earth-lit
part. Exposure 3 shows it off the south-east limb. Apparently 20
minutes later took 2 exposures and frame 18 was a double. The
second exposure revealed an object farther from the limb but the
first exposure does not show the object. The two high power exposures
do not show it. Cameron could not see the spots that Johson describes
on his slides, but did see several spots (defects?) on the
8 and 12 second exposures near Hevelius and also on the 20 second
exposure near to Hecataeus only. BAA members observed star like

Burg 2020 Dec 20 UT 19:00-20:08 (T.Smith, Codnor, UK, 16"
Newtonian, seeing III-IV) observed visually that this crater
was very red on its western floor and rim. A similar effect
seen in Plinius, elsewhere on the Moon. No red was seen to the
exterior of both craters. The redness on both of these craters
had become diluted by 19:40. Also around this time, it was
noted that Proclus had a slight redness to its western
interior, though by no means as strong as in Burg and Plinius.
A comparison with Censorinus revealed no redness to this
crater. By 20:08 Burg was only showing a hint of red at times.
ALPO/BAA weight=1.
Plinius 2020 Dec 20 UT 19:00-20:13 (T.Smith, Codnor, UK, 16"
Newtonian, seeing III-IV) observed visually that this crater
was very red on its western floor and rim. A similar effect
seen in Burg, elsewhere on the Moon. The central peak of
Plinius was very easy to see and also looked red in colour. No
red was seen to the exterior of both craters. The redness on
both of these craters had become diluted by 19:40. Also around
his time, it was noted that Proclus had a slight redness to
its western interior, though by no means as strong as in Burg
and Plinius. A comparison with Censorinus revealed no redness
to this crater. By 20:08 Plinius still had a slight red hue
but Burg was only showing a hint of red at times. Observations
ceased at 20:14 due to the Moon being hidden by an
obstruction. ALPO/BAA weight=1.
Proclus 2020 Dec 20 UT 19:40 (T.Smith, Codnor, UK, 16"

Proclus had a slight redness to its western interior, though
by no means as strong as in Burg and Plinius which exhibited
stronger red colours. A comparison with Censorinus revealed no
redness to this crater. ALPO/BAA weight=1.
Theophiuls 2020 Dec 20 UT 19:00 (T.Smith, Codnor, UK, 16"

On 1989 Feb 11 at UT23:30-01:39 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x159, seeing=7/10) observed a linear east to west feature in
Proclus. D. Weier (WI, USA, 11" reflector, x378) found the NNW part of
the crater to be brighter than expected and confirmed the prescence of
the east to west feature - this crossed the shadow on the east floor
and over into Mare Crisium. R. Manske (WI, USA) detected another
"streak" parallel to this. All observers suspect that the linear
features were due to raised topography on the floor of Proclus -
however Cameron comments that there does not seem to be any linear
features on the floor of Proclus to cause these effects. The Cameron
2006 catalog ID=351 and the weight=5. The ALPO/BAA weight=2.

On 1973 Dec 02 at UT 22:17:33 Barrett and Brick (New York, 3.5" Questar
freflector) observed an occultation of Kappa Aquari, a wide double
star, on the western limb. The star faded perceptably before
disappearing. Cameron says that the fact that the star was a double was

in brightness of Mons Piton point D (his designation) during 04:56-
04:59. The whole of the east slope was affected - initially bright and
then faded and there was a blue colour (detected with filters). The
variabilty was 8-11sec (Cameron suspects atmosphere as the altitude was
low). The brightness stabilized at 05:12UT, but variability resumed
until observing finished. As a comparison Aristillus was not seen to
change. The Cameron 2006 catalog ID=287 and the weight=1. The ALPO/BAA

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

in the dark side of the Moon, a few km east of Kies crater, a bright
point that should not be poking out of the shadow (according to Foley).
The Cameron 2006 catalog ID=244 and the weight=3. The ALPO/BAA
weight=2.
127mm f/12 GoTo scope, x62-x154, seeing: best and transparency=
6) observed that an unoficially named mountain (Lambert Gamma or
Mons Undest), near Lambert, had a "very strong glow", especially
the part that was facing the line of the terminator and this was
brighter than the side facing away. The No other object nearby
was casting as much light, even Mons La Hire. The effect was
seen for 40 minutes and the glow was present throughout. The
ALPO/BAA weight=2.
On 1974 Jan 03 at UT 18:30 a Norwegian amateur astronomer,
Hoydalsvik (Hakonsgate, in West Norway, 60mm refractor)
photographed the Moon using High Speed Ektacrome (400ASA) film
with good focus. The TLP was located on the southern slope of
Sasserides H and was pink in colour with some bluish in it.
The coloured area was circular with a diameter of 0.5 minutes
of arc. Only one exposure was taken. The photograph was
checked by the Institute of Theoretical Astrophysics,
University of Oslo. Although they thought it was probably
genuine (could have been an impact flash?) suggestions by the
BAA lunar section favoured static electrical discharge on the
film. It is uncertain whether the film was ever examined by a
Photographic developing lab such as Kodak, who would be able
to tell if it was real or an artefact. ALPO/BAA weight=1.
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 1967 Oct 13 UTC 19:17-20:00 Observers: Henshaw (Mansfield, UK,
8.5" reflector x112) and Corralitos Observator (Organ Pass, NM, USA,
24" reflector) "Phenomenon (brightening ?) nr. NW (ast. ?) lasting for
3s. Cont'd for 45m but nothing else unusual, (nr. Gass or in it?).
Corralitos MB did not confirm." NASA catalog weight=3 (average). NASA
catalog ID #1050.
Gassendi 1966 May 30 UT 20:32-20:59 Observed by Sartory (England, 8.5"
reflector + filters) "Orange patch & obscuration -- detected by Eng.
moon blink system. Color seen visually."NASA catalog weight=4 (good).
NASA catalog ID #941.
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 1955 Jan 05 at 01:00-01:30 UT D.A. Logue (Larchment, PA,
USA, 15cm reflector at x340, seeing Good) saw a strange blue
light above the surface of the Moon where the night and the
day meet. He observed this light for more than 30 min and it
did not appear to move. It appeared like a star in that the
rays of light came from it. The observer adds that he first
thought thst the objects was a star, but later decided that it
had to be on the Moon itself. A drawing shows the blue spot
near the rugged south west (IAU?) limb of the Moon. The editor
of the Strolling Astronomer (Vol 8, No. 11-12, Nov-Dec 1954,
p146) was unable to identify the craters drawn. The editor
speculates that the observer saw a high mountain peak with its
summit in sunlight and detached from the illuminated regions -
however this would not explain the blue colour. Note this is
an ALPO observation and does not apear in the Cameron
catalogs. ALPO/BAA weight=2.
On 1964 Jun 21 at UT 03:43-05:44 Harris, Cross and Helland (Whittier,
CA, USA, 19" reflector) observed south of Ross D: "Moving dark area".
The Cameron 1978 catalog ID=819 and weight=4. The ALPO/BAA weight=4.
On 1825 Jan 01 UT17:00? an unknown Russian observer noticed a
cloud in Mersenius.
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 2017 Sep 02/03 UT 23:55-00:30 A.Anunziato (Parana,
Argentina, 105 mm Maksutov-Cassegrain, x154, seeing 6/10, some
interuption from clouds) observed a light spot SE of the
centre of the floor of the crater, which came and went in
visibility. There is a light spot here, but what was unusual
was that the visibility decreased over time.
ALPO/BAA weight=1.
nr Fra Mauro 1970 Aug 14 UT 05:00? Observed by Bell (Californina).
"Bright blue-white flare (meteor?)(call for obs. at Fra Mauro at
perigee because of moonquakes there -- therefore biased to tidal
hypothesis. That was the original location given for the A1 moonquake
site, but it is located elsewhere now. Ancill. data given for 1970)."
NASA catalog weight=1. NASA catalog ID #1273. ALPO/BAA weight=1.
Herodotus 1950 Mar 30 UT 19:00? Observed by Wilkins (Kent,
UK, 15" reflector) "Transient c.p. (similar phen. to
Bartlett's in later yrs.? see #532). NASA catalog weight=4
(good). NASA catalog ID #523. ALPO/BAA weight=3.
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,
red, & yellow, but duller in blue. Floor est. 2deg, distinctly
olive-green. Precise time at 0117 at col. 55.27deg" NASA catalog
weight=4. NASA catalog ID #655. ALPO/BAA weight=3.
Herodotus 2022 Nov 06 UT 00:05-00:38 A. Anunziato (Parna,
Argentina - 105mm Meade EX 105, x154). Glimpsed an elongated
light patch on the floor, slightly east of the centre of the
floor. Observer was a bit uncertain if this was a genuine
observation, or a biased observation – based upon the written
account in the repeat illumination predictions. Detailed
sketch made. Anyway, seeing detail on the floor of Herodotus
was at the limit of his telescope. We shall therefore assign
an ALPO/BAA weight of 1.
