On 1981 Aug 09 at UT05:08-05:21 D. Louderback (South Bend, WA, USA, 3"
refractor) found that the bright patch in the southern part of Eimmart,
could only be seen well in red light (this is between A, C and D in his
feature notation) i.e. 5 brightness values higher than in white or blue
light. Indeed in white light this bright area was closer to the east
wall bright spot. The Cameron 2006 catalog ID=149 and weight=4. The
ALPO/BAA weight=2.

Proclus 1972 Jul 19 UT 21:24-21:30 observed by S.Westmoorland
(Cropwell-Bishop, UK, 15cm reflector, x48 & x96, image dull
but steady) observed a brilliant spot in the NE (IAU?) wall
which lasted for about 90 seconds. After fading it was
replaced by pulsations for a further 2 minutes. Clouds
prevented further observations. ALPO/BAA weight=1.
On 2001 Jun 29 at UT22:16-22:22 C. Brook (Plymouth, UK, 60mm refractor,
x120, no spurious colour seen, seeing I) observed that the central
peaks of Alphonsus looked bright at 22:16UT but had dimmed by 22:22UT.
The three dark patches on the floor of Alphonsus were clearly seen. The
ALPO/BAA weight=1.
On 2001 Jun 29 at UT 22:16-22:20 C. Brook (Plymouth, UK, seeing
conditions very good, x120) reported that the central peak of Alphonsus
was brighter than the central peak of Arzachel (or was it the other way
around?). Cook observed 4 hours later from Washington DC, USA and found
that on CCD images that the central peak of Alphonsus was only slightly
less than that of Arzachel. The ALPO/BAA weight=2.
On 1994 Apr 19 at UT 22:00 R. Knopp (Berlin, Germany) noticed a
darkening of the interior of the crater Atlas. The ALPO/BAA weight=1.

On 1988 Mar 27/28 at UT 23:30-00:30? M.C. Cook (Frimley, UK, 12"
reflector) noted that the crater Proclus was bright visibly, but the
CED brightness measurement gave the same brightness as Censorinus
crater. The Cameron 2006 catalog ID=321 and the weight=4. The ALPO/BAA
weight=2.
SE of Ross D 1966 Oct 24 UT 03:17 Observed by Cross (Whittier,
CA, USA, 19" reflector, x300, S=3-5, T=3-4) Ross D activity at
level 5. ALPO/NAA weight=1 as it is not mentioned in the Cameron
catalog.
On 1968 Oct 01 at UT 21:00? Bartlett (Baltimore, MD, USA) and Beck
(Ohio, USA, x437) observed lack of detail on the floor of Plato,
however the wall of the crater was easily resolved. Cameron says that
this was an independent confirmation. The Cameron 1978 catalog ID=1092
and weight=5. The ALPO/BAA weight=3.
On 1986 May 18 at UT 20:45-22:25 M. Mobberley (Suffolk, UK, seeing II-
IV) found that the central craterlet of Plato was an ëasily seen "white
splodge" although it was quite difficult to see when imaged with video.
Foley and Cameron comment on IR sensitivity of the CCD camera used. The
Cameron 2006 catalog ID=285 and the weight=1. The ALPO/BAA weight=1.
Alphonsus 1966 May 29 UT 21:45-22:45 Observed by Wise (England, 4.5"
reflector, x125). and Corralitos Observatory (NM, USA). "Glint lasting
1.5s. (onset of Smith's anomaly? Specular reflection should last
longer). Not confirmed by Corralitos MB, (however they report Gassendi?
misident., or did they obs. another feature?). At UT 22:45 Smith and
Brown (England, UK, 10" reflector) observed reddish patches in
Alphonsus. Negative results from Brown though at 21:21Ut and 22:25UT).
The Cameron 1978 catalog ID=939 and 940 and weight=4. The ALPO/BAA
weight=3.
On 1984 Jun 09 at UT 04:55-05:14 P. Jean (Outremont, Canada) detected
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.
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.
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 1980 Aug 21 at UT20:00 J.H. Robinson (Teighmouth, Devon, UK)
detected colour, using a Moon Blink device, and "mistiness" on the
southern floor of Tycho crater. The seeing was poor! Cameron 2006
catalog ID=104 and weight=1. ALPO/BAA weight=1.
Plato and Plato A 1972 Jan 26 UT 18:25-18:55 Observed by Watkons and
Hunt (England, 4.5" reflector x150, x225, and a 2.75" refractor) "Misty
patch over A, & a misty brightness over SW wall of Plato. Hunt saw
nothing unusual." NASA catalog weight=2 (low). NASA catalog ID #1321.
Plato 1967 May 20 UT 01:13 K.Simmons (Jacksonville, FL, USA, 10"
reflector) observed a large bright (intensity 6.5) oval area on
near the central floor. According to Ricker and Kelsey (ALPO
selected area coordinators) this is unusual. ALPO/BAA weight=1.
SE of Ross D 1966 Oct 25 UT 03:46 Observed by Cross (Whittier,
CA, USA, 19" reflector, x300, S=2-4 (sometimes 5), T=3-4) "Large
bright area obscuring 1/2 of Ross D crater wall. Not present Oct
24" NASA catalog weight=3 (average). NASA catalog ID 986.
Actually some activity was observed the fay before according to
the original notes. ALPO/NAA weight=2.
Archimedes 1973 Jun 11 UTC 21:05-21:15 observed by Pasternak (53deg
20'N, 7deg 30'E, 75mm reflector) "Faint red area at the E of Archmedes,
diminution from 21.10-21.15UT" - Hilbrecht and Kuveler, Earth, Moon &
Planets, 30 (1984), p53-61
Om 1987 Sep 04 at UT 03:00 J. Caruso (Middletown, CT, USA, 3"
refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not
visible, however Heraclides E, Helicon G, and indeed many other smaller
craters could be seen. There were two small mountains in the general
area of Bianchini G. and a mare ridge - all these were clearly seen.
Caruso states that Bianchini G should normally be much more clearly
seen than the other features mentioned and is the same size as
Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3. The
ALPO/BAA weight=1.
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.
Plato 1873 Nov 01 UTC 20:00? Observed by Pratt (England?) "Unusual

ALPO/BAA weight=1.
On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in
Gassendi - some obsevers detected colour, others did not. P. Moore did
not notice anything unsual earlier at 18:50-19:00, though his seeing
was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing
was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also
reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did
however notice a small reddish spot to west of central ridge, but by
20:30UT the colour was less obvious, but the spot was back again at
20:45, but not easily seen at 21:00 and gone completely by 21:45UT.
N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red
patches on the floor between 20:54 and 21:31UT. A BAA Lunar Section
report. ALPO/BAA weight=3.
On 1980 Aug 22 at UT20:15-21:29 J-H Robinson () detected violet on the
west wall of Aristarchus. Cameron 2006 catalog ID=105 and weight=5.
ALPO/BAA weight=2.
On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK,
12" reflector, x200, seeing=II) noticed in the area south east of
Manilius that it was brighter in red light than in blue light at
20:15UT whereas 1 minute later it was the same brightness in each
filter. The effect reappeared at 20:21UT and was particularly strong at
20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was
of high reflectivity in white light and was bright in red at 21:15UT,
thougjh the south east area stopped giving a colour reaction at
21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT
however at 23:55UT it was surrounded by a transient white ring that
varied in visibility in an irregular way. Foley found Manilius B had a
vivid blue interior and in blue light the ring was black. and not at
all seen in red or white light. The CED brightness measurement varied
from 1.9 to 2.4. All other regions observed were normal in brightness.
Violet was seen on the west wall of Aristarchus though. M.Price
(Camberley, UK) found a possible blink in Manilius B but was observing
under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5.
ALPO/BAA weight=4.
Gassendi 1968 Oct 03/04 UT 19:30-19:50 & 00:20-01:40 Observed

and by Moore (Selsey, Sussex, UK, 12.5" reflector, x360)
"Slight blink (Eng.) arcuate in shape, N. of c.p. (Rawlings
dubious). Moore, with blink device saw none at 0020-0140h. No
LTP in Gass., Ptol. or Aris. 5th or 6th.". NASA catalog

On 1964 Jun 21 at UT 21:18 Lipskii and Pospergelis (Shternberg State
Ast. Institute, AZI-2" reflector (Cass.) observed Aristarchus:
"Polarization meas. with electron polarimeter. Plane of polariz.
rotated 2deg fr. the adjacent areas. They interpret it as some
scattering medium over the crater. (Source gave date as 6/31/64,
misprint =21st?)". The Cameron 1978 catalog ID=820 and weight=5. The
ALPO/BAA weight=4.
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.
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 1825 Jan 01 UT17:00? an unknown Russian observer noticed a
cloud in Mersenius.
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

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.
Aristarchus area 1967 Apr 21 UT 19:00-21:20 Observed by
Darnella (Copenhagen, Denmark, 3.5" refractor, S=1-2),

On 1993 Jun 02 at Ut 04:30-05:45 S. Beaumont (Cambridge, UK) saw that
the shadow of the Cobra's Head in Schroter's Valley was lighter and
more diffuse seen at user defined locations of C or B rim (these were
black versus medium gray for Cobra's Head). The TLP had vanished by
05:45UT. The Cameron 2006 catalog ID=462 and weight=3. The ALPO/BAA
weight=1 because the date or time is wrong.
On 1984 Nov 05 at UT18:00 Marshall (England) noted that there was no
normal brightening on the floor just next to the southern most
craterlet. The Cameron 2006 catalog ID=251 and the weight=2. The

On 1985 May 02 at UT 20:20-20:38 J.D. Cook (Frimley, UK) noted at 20:20
found the south rim (and just outside) to be blurred in appearence and
there was also a hazy shadow inside the crater. M.C. Cook found a
"break in clarity in break on S wall". Miles (UK) also found the south
wall blurred in appearance and Foley (Kent, UK) noted that the area was
featureless and the 2 craters positions at 1 o'clock high up on the
inner wall were obscured", although just north of these was sharp
detail. Foley also recorded that the shadow on the east wall was
opaque"and that thye inside of Aristarchus was slate/blue in colour and
dull, however by 20:28 the crater had brightened by 0.4 steps on
Foley's CED device and the missing craterlets were visible again. Jean
(Canada, 4" refractor) observed a rose colour intermittently (UT 1948-
20:58) - however Cameron suspects that this is chromatic aberation.

III from 20:15-22:30, but the clouded out at 22:30, and from
23:15-01:15 seeing was IV-V with poor transparency) observed
(22:20-20:45 UT) variation in the SE corner of the
Aristarchus, namely the usual dark bands were alternating
light to dark, not in keeping with otyher crater features.
This effect was not linked to atmospheric turbulence. Also
projected image of bands beyond the crater W. wall were
repeatedly noted. The observer broke away from observing at
20:45UT to make a telephonealert call. At 20:55UT they noted
that the area between Vallis Schroteri and Herodotus seemed
very light/bright, also the E. exterior of the crater wall of
Herodotus. From 21:01-21:11 A slight blueness was seen to
extend from the NE corner of Aristarchus, along the exterior
rim, acrossand beyond Herodotus to the SW. A tgorough search
was made of many bright areas, both near the terminator and to
the E., but no blueness could be detected elsewhere. A slight
orange hue was noted along the E. limb of theMoon (Spurious
colour). From 21:18;22:30 Aristarchus seemed normal again, and
likewise the head of Vallis Schoteri too. The observer was
clouded out from 22:30-23:15and from 23:15-01:30 the seeing
was so appaling that no colour or projection of the bands
could be seen. A Moon Blink was used during the session, but
no colour was detected in this? Another observer, R.W. Rose
(Devon, UK) observed 21:20-21:30 but had IV seeing, and saw
nothing unusual, but commented that if TLP wactivity had been
taking place, then they would probably not have seen it. The

On 1988 Apr 01 atUT01:15-03:20 H.Hill (Lancaster, UK, 10" reflector,
x286) observed that east of Lichtenberg were ëxtensive rosy areas"
around the northern edge of the lava sheet. Hill believes that it may
have been the same effect as seen by Madler (Germany), Barcroft (USA)
and Baum's (UK) 1951 observation. The colour was "ünmistakable" and
nothing to do with the atmospheric spurious colour. Other features were

transparency, good) noticed in Aristarchus, blue to the north west
(IAU?) internal wall, also blue observed in other small bright objects
against dark backgrounds. Lunar rotational axis and optical normal
related such that the normal runs NW-SE (IAU?) through these features.
Observer deduced that the coliur was obviously spurious and no blink
was seen in any feature. The blue disappeared as the lunar altitude
increased and no blue seen by 00:00UT. This is a BAA lunar section

On 1970 Aug 17 at UT 02:40 Pedler (England) noted that the
shadow flowed around instead of over Plato. Wondered if shadow
matched the gray of the crater. Within minutes the shadow line
looked normal again. At 04:41UT Claudio Pamplona (Brazil) saw a
pulsation in Plato during a lunar eclipse. He thought that this
was due to falling temperatures. The Cameron 1978 catalog ID=
1274 and the weight=0. The ALPO/BAA weight=1.

On 1963 Jul 06 at UT 21:00 (estimated) Chernov (Russia) observed that
the dark spot in Riccioli size increased suddenly during a lunar
eclipse as it entered the shadow, before merging with the shadow. The
mid eclipse was at 22:03UT. The cameron 1978 catalog ID=774 and
weight=1. The ALPO/BAA weight=1.
In 1921 Oct 16 at UT 22:00-00:00 Genin and others (Russia) observed
during a partial eclipse that different parts of Aristarchus crater had
brightness of phosphorecence. Cameron says that this is independent
confirmation. The Cameron 1978 catalog ID=383 and weight=5. The
ALPO/BAA weight=3.
On 1956 Nov 18 J.P. Bagby organized a lunar eclipse observing session
in the USA. He recorded 35 bright objects against the Moon, 5 of these
were seen by 3 other observers. J. Mavrogianis and 4 other observers
observed 25 transient luminous objects - mostly stationary yellow
flashes. However another group at Cheyenne noted a 4 sec duration
light. This report is described in H. Hars "The Total Lunar Eclipse of
November 18, 1956", Strolling Astronomer, 11:64, 1957.
On 1971 Aug 06 at UT 20:30 Chernov (Crimea?, Ukraine, Soviet Union)
observed a dark spot in Riccioli that was very dark for 3 minutes,
before coming out of shadow - however the dimensions were normal. This
was during the lunar eclipse. The Cameron 1978 catalog ID=1305 and
weight=3. The ALPO/BAA weight=1.
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 1971 Aug 06 at UT 21:00 Chernov (Crimea?, Ukraine, Soviet Union)

1306 and weight=2. The ALPO/BAA weight=1.
On 1975 Nov 18/19 at UT 23:15-0005 LeCroy Jr and Sr (Springfield, VA,
4.5" reflector, S=7) observed that Delambra was one of four glowing
spots on the Moon during a lunar eclipse (including Aristarchus). At
23:50UT 3 of these patches emerged from the dark and appeared as bright
spots compared to other craters "Älbedo=10+". The Albedos of Manilius
and Delambre were 8.5 at 00:05UT. Details became apparent in all 3
features. The Cameron 1978 catalog ID=1419 abd weight=0. The ALPO/BAA
weight=1.
On 1975 Nov 18/19 at UT 23:15-0005 LeCroy Jr and Sr (Springfield, VA,

On 1975 Nov 18/19 at UT 23:15-0005 LeCroy Jr and Sr (Springfield, VA,
4.5" reflector, S=7) observed that Menelaus was one of four glowing
spots on the Moon during a lunar eclipse (including Aristarchus). At
23:50UT 3 of these patches emerged from the dark and appeared as bright
spots compared to other craters "Älbedo=10+". At 23:55UT a ray appeared
out of the north east rim of menelaus (Normal?). It appeared just
before the artea emerged and increased in brightness. At 23:58UT it
decreased and continued to do so. The north east edge of Menelaus
appeared very dark at the point that the ray was extending from SW edge
(a ridge there) and apperared to obscure features along its path
(Albedo=9). The Albedos of Manilius and Delambre were 8.5 at 00:05UT.
At 00:05UT the rays were still apparent but seemed to have returned to
normal. Details became apparent in all 3 features. The Cameron 1978
catalog ID=1419 abd weight=0. The ALPO/BAA weight=1.
Moving glows seen around the middle of the
disk during a lunar eclipse.

On 1979 Aug 12 at UT07:00-10:35 D. Darling and wife (Sun Prarie, WI,
USA, 12.5" reflector, x342, photos, S=9/10) observed a cigar shaped
protruberance in Romer crater that cast a 32km long shadow, nestled in
a valley rille next to Romer. This was a confirmed observation. The
effect persisted intil sunset. The top of the object and two points on
the crater rim were reflecting the Sun's rays. "Top of obj. & 2 pts on

On 1964 Jun 29 at UT 07:05-07:33 Bartlett (Baltimore, MD, USA,
4" reflector x240, S=5, T=4) suspected a violet glare? on the
EWBS of Aristarchus, but was too faint to be certain. The bright
art of the floor was granulated and had a ceppery tint. The
Cameron 1978 catalog ID=827 and weight=4. The ALPO/BAA weight=2.
On 1964 Jun 30 at UT 05:50-06:10 Bartlett (Baltimore, MD, USA) observed
the following in Aristarchus: "Nimbus only -- dark viol. hue. S. part
of Aris. floor was granualated & a brown tinge -- changed to yellow & a
brown tinge at 0500. First time he ever saw such a change in color.

On 1973 Dec 18 at UT06:35-06:38 Pasternak (53deg 20' N and 7deg 30' E,
using 75mm reflector, focal length 700mm, transparency 1 out of 5 and
seeing 2 out of 5) observed a faint brightening in the south wall of
Aristarchus. Published in Hilbrecht and Kuveler, Moon and Planets, 30

On 1983 Dec 28 at UT03:30-05:00 Moseley (Covington, England, UK,
seeing=V-IV and transparency=good) detected some detail within the
shadow under good moments of seeing. The external brightness was
extended to the east wall at a clock position of 9 O'clock, but did not
go outside the rim. It was less bright at the 11 O'clock position. The
Cameron 2006 catalog ID=236 and the weight=3. The ALPO/BAA weight=2.
On 1941 Mar 31 UT 03:15 Barcroft (Madera, CA, USA, 6" reflector)
observed Aristarchus in Earthshine - Haas thought it must have been
unusually bright. The Cameron 1978 catalog ID=486 and weight=3. The
ALPO/BAA weight=2.
South Pole 1997 Apr 10 UTC 20:45 Observed by Livesey (Scotland, 65x33,
Seeing Antioniadi II, Transparency : Thick Haze Alto Stratus, windy)
"Two bright spots seen - one on southern tip of crescent and 2nd way
over on the dark side of the S. limb. Earthshine seen, but no
features". Probably these are just peaks making it into sunlight -
though one of them was of considerable distance from the tip of
the cresecent (was this the peak of eternal light?). So therefore
the ALPO/BAA weight=1 i.e. it is worth checking out - however we
may not be able to tell for sure until the libration matches
up too.
On 1988 Feb 20 at UT22:25-22:34 H. Rodriguez Moreira (Fortaleza,
Brazil, 4" refractor) observed a rapid rise in brightness at
22:25UT in Promintorium Olivium. About 4 minutes after this the
brighness fluctuated 3 times and the TLP faded in 9 minutes
after it started, returning everything to normal. "Bluish light
point on darkside of it" - apparently a Greek observer (Aguirre)
observed a flash but no date was given. The Cameron 2006 catalog
ID=317 and the weight=3. The ALPO/BAA weight=3.
On 1821 Feb 06 at UT 18:00-19:00 At 18:00UT H. Kater (London, UK),
Olbers (Bremen, Germany), Browne (UK), commented that Aristarchus
looked like a 6-7th magnitude lumninous star, some 3-4' in diameter. At
19:00UT Aristarchus looked like a cloudy spot according to Ward and
Bailley (England, large telescope, x80). The Cameron 1978 catalog ID=
84-85 and the weight=5. The ALPO/BAA weight=3.
Schroter observed Aristarchus to be extraordinarily bright on the dark
side of the Moon. Cameron 1978 catalog ID=30 and weight=4. ALPO/BAA
catalog weight=2.
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 1984 Jan 08 at UT16:30-18:40 P. Moore (Selsey, UK, seeing=III) could
not see Aristarchus in Earthsine, despite, Tycho and the mare regions
being plainly visible. Foley (Kent, UK) found Aristarchus to be a "soft
blue patch" and North (seeing IV-V) found the crater to be one of the
brightest features on the Moon. The Cameron 2006 catalog ID=237 and the
weight=0. The ALPO/BAA weight=1.
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.
On 1867 Apr 09 at UT 19:30-21:00 Elger(Liverpool? UK, 4"? aperture
telescope) observed that Aristarchus was shining like a 7th magnitude
star-like point, becoming fainter, almost extinguished at 9PM. He had
seen lights before but never so strong. The Cameron 1978 catalog ID=151
and he weight=4. The ALPO/BAA weight=2.
Nebulous appearance. Cameron 1978 catalog assigns
an ID No. of 12 and a weight of 1. ALPO/BAA catalog
assigns a weight of 1.
On 1972 Dec 11 at UT22:28 Cernan, on board Apollo 17, saw a flash on
the east rille in Mare Orientale (88W, 20S) as he orbited the Moon. The
Cameron 1978 catalog weight=1354 and the weight=3. ALPO/BAA weight=2.

NASA catalog ID #721. ALPO/BAA weight=2.
Messier 1981 Feb 10 UT 19:20-20:10 TLP discoevered by Hedley
Robinson (Devon, England) "Messier was brighter than Aristarchus
in both red and blue filters and also appeared indistinct, later
becoming invisible - lost in a bright streak. In comparison
Aristarchus was clear. Another observer, Amery confirmed that
Aristarchus was sharp in appearance but Messier certainly was
not. Cook likewiese found Messier not to be as sharp as Messier
A dueto a big shadow in Messier A. Pedler found that the sun
facing wall of Messier was OK but that the shadow was changing
from black to grey periodically at intervals of 2-3 minutes to a
few seconds. By contrast he found that Messier A remained quite
well defined. He tried red and blue filters but found no blink
effect. At 20:23UT Pedler found that the shadow had stabilized
to a shade of "mid grey" although remaining ill-defined. North
also found that Messier A was distinct but Messier itself was
ill-defined. Moore found the same thing but thinks that this is
normal for Messier under this illumination to appear indistinct.
More also saw the grey interior shadow. Price saw similar
appearance to Moore and suspected that this was normal for this
stage in illumination. Ratcliffe suspected everything normal -
just commenting that Messier was smaller and no detail in
comparison to Messier A. Madej and Taylor provided a sketch that
showed again a grey interior and merging with the east
wall/mare. Foley found Messier's pale grey interior to be un-
focusable but in comparison Messier A was sharp. He says that he
would expect a grey interior and the east wall to merge with the
mare. However the complete loss of deatil and variability were
not normal. Cameron comments that the Kuiper atlas confirms the
fuzzy indistinct appearance of Messier and that a Lunar Orbiter

On 1997 Apr 14 at UT 20:00-22:00 F. Paolo (Legnano, Italy)
photographed a lunar flare on the lunar limb.
Limb North? 1881 Jul 04 UT 00:30 Observed by Several observers
(Lebanon, CT, USA, naked eye, alt @ 10 deg) "2 pyramidal protruberances
on upper limb (dark?). Points were darker than rest of moon's face then
slowly faded away (atm ? moon very low)" NASA catalog weight=? NASA
catalog ID #223.
On 1993 Jun 27 at UT 19:55-20:21 and 20:24-21:04) D. Kane (England? UK,
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
filters. The Cameron 2006 catalog ID= and weight=3. The ALPO/BAA
weight=2.
Proclus 1972 Aug 17 UT 20:05-21:10 Observed by Haiduk (13.25E, 52.5N,
60mm refractor, S=1, T=3) "Well visible bright area at the NE wall, end
of event uncertain for seeing became poor" Hilbrecht & Kuveler Moon &
Planets (1984) Vol 30, pp53-61.
Plato 1967 Apr 18 UT 03:10-04:00 Observed by Kelsey
(Riverside, CA, USA, 8" reflector x300, S=8, T-4-5). "Streak
on floor showed slight enhancement in red filter comp. to
blue. Later, a 2nd streak formed. Probably the sun shining
thru a valley in the rim. Red enhancement permanent? (Wise
suspected a blink here 6h earlier)." NASA catalog weight=3.
NASA catalog ID #1027. ALPO/BAA weight=1.
On 1867 Apr 12 at UT 19:30-21:00 Elger (Liverpool? UK, 4" aperture
telescope) observed Aristarchus in Earthshine "grew fainter 7th mag.
star; much fainter in last 15 min. & barely perceptible at 9PM. Had
seen something similar on former occ." The Cameron 1978 catalog ID=152
and the weight=4. The ALPO/BAA weight=2.
In 1824 Jul 04 at UT23:00? Emmett (England, UK) observed a star-like
light on the rim (in the dark). The Cameron 1978 catalog ID=100 and the
weight=3. The ALPO/BAA weight=2.
Plato 1964 May 20 UT 01:00-01:30 Observed by Bartlett (Baltimore, MD,
USA, 2.4" refractor x117, S=6, T=5). "Orange-red color on W. wall.
Vivid" NASA catalof weight=4 (high). NASA catalog ID #813.
Eratosthenes 1976 Jun 06 UT 02:01 Observed by Bartlett
(Baltimore, MD, USA, 3" reflector x54-300, S=5, T=5) "Bowel was
full of shadow but a small 5 deg bright spot on NE floor.
Nothing seen in 1975 at nearly same col. but shadow was deeper."
NASA catalog weight=4 (high). NASA catalog ID #1432.
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
and a bright patch to the north of the central peak brightned
slightly wrt the its surroundings. However seeing conditions
worsened as the observing session progressed, and in view of
this the ALPO/BAA weight=1.
Tycho 2003 May 09 UT 21:04 Observer Brendan Shaw (UK) "CCD
image of central peak - Sun's altitude suggested that this
should not have been directly illuminated this early - may
have been from secandary reflectance off illuminated W wall?"
ALPO/BAA weight=1.
Alphonsus 1966 Apr 28 UT 21:58 Observed by Smith (England, 10"
reflector) and Corralitos Observatory (Organ Pass, NM, USA, 24"
