Messier A 1951 Aug 20 UT 01:48-03:00 Observed by P.Moore
(England, 8.5" reflector, x350). Bright cloud like circular
patch seen on S wall of Messier A. It was the brightest object
in the vicinity. Observations ceased due to the Moon setting
behind a tree. W.Haas thinks that this effect is not unusual at
similar colongitudes. Moore checked again under similar
illumination and still considers the Aug 20 appearance abnormal.

On 1993 Dec 31 at UT 05:00-07:40 S. Beaumont (Cambridge, UK, 12"
reflector) "saw a patch of hazy light to NW (from c.p. alpha) at 0550
craters B & J shadow of alpha had not reached E wall yet, but at 0536
it did. Alpha > at 0550. Craters B & J to SE had faded, vanished at
0630. Hazy patch remained around peak, alpha low mainly to NE like a
comet's tail. Slightly reddish fringe to E wall. (shown in sketch)".
The above has been quoted in full from the Cmeron catalog because the
catalog desription is slightly ambiguous and any attempted summary
might make the description more unreliable. The cameron 2006 catalog

reflector, x75 and photography used, seeing 4/10 and the Moon's
altitude was 45deg) photographed Romer crater and recorded two adjacent
bright cigar shaped objects - these were the same size as an
observation made in 1987. Darling believes that these are ridges.

On 1974 Jun 12 at UT0256 an unknown observer noted a dark blob on the
northern edge of the floor of Pitatus crater.
On 1916 Jan 27 at 22:00? Markov (Russia) noticed that a light sector
was visible at the bottom of Plato, in shadow, and contained 3 bright
spots, reminiscent of phfescent bodies. The Cmaeron 1978 catalog ID=362
and weight=3. The ALPO/BAA weight=3.
On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52"
reflector) observed that central craterlet in Plato was
unusually bright and shows up as a bright white spot on his
sketch - though this might have been artistic license in his
sketch. His written notes refer to the unusual lack of a rim
(especially the northern part) to this craterlet.
The ALPO/BAA weight=2.
Aristarchus 1970 Jul 26 UT 15:00? Observed by Sekiyuchi (Tokyo, Japan,

On 1979 Sep 16 at UT 08:00-09:00 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x62-x97, clear, but Moon at low altitude) detected
four new features that he had not seen before in Earthsine in
comparison with what he saw on 16 Jul 1979, this time in the southern
part of the Moon. pin-point flashes were seen within these bluish
areas. Each time a flash occurred the gas clouds brightened (sometimes
by 6x) for a few seconds. Cameron thinks that these are related to
moving clouds on the Earth's limb e.g. mackeral sky. Cameron 2006
catalog ID=69 and weight=1. ALPO/BAA weight=1.
Briggs A 1980 Feb 11 UT 06:30-07:00 Observed bt Butler_FC
(Brixton, UK, 22cm Newtonian reflector, x64, x104, seeing IV).
Found Briggs A to be brownish in colour at x64, however the
colour vanished at 06:55 when x104 was used. Switching back to
x64 the colour was still there but fainter. The colour fade may
have been due to day light glare encroaching? Could not see this
effect anywhere else on the Moon but did detect what he regarded
as a permanent coloured spot (yellow) between Cruger and
Grimaldi. ALPO/BAA weight=1.
Gauss 1968 Sep 18 UT 08:00? Observed by Chilton (Hamilton, Canada, 11"
reflector) "Observing thru polaroid filter, E. (IAU?) wall was invis;
but became vis. when filter was rotated, indicating refl. of polarized
light. Same area examined since, but no such phenomenon." NASA catalog

On 1982 Jul 18 at UT 04:12-04:22 A. Ansari (Queen Mary College London,
UK, a naked eye observation), upon examining the cresecent Moon,
detected a bright flash from the Plato region. Two more flashes were
seen at 04:22, about a second apart, and the latter was the fainter.
The Cameron 2006 catalog ID=176 and weight=3. The ALPO/BAA weight=2.
On 1979 Sep 25 at UT00:40-00:51 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x62) found the crater to blow and fluctuate between
magnitude approximately 4 and 5. Initially it was bright, then faded,
then brightened again aggroximately x2 and then faded into the
background. The Cameron 2006 catalog ID=70 and weight=0. The ALPO/BAA
weight=1.
Aristarchus 1949 May 01 at UT 20:45 H.P. Wilkins (Kent, UK, 3"
refractor x100) observed Earthshine was very detailed and
Aristarchus was noticeably a bright patch. Upon concentrating on
Aristarchus, he observed that it flared up in brightness
considerably more still for about 2 sec. During this flare up
time, inner terraces and the central peak became visible.
Cameron says that this was confirmed by Barcroft a few hours
later???? The Cameron 1978 catalog ID=518 and Weight=5. The
ALPO/BAA weight=3.
In 1900 Nov 26 at UT 19:00? an unknown observer (in Europe) observed a
suspicious obscuring phenom on a dark plain (mare). The cameron 1978
catalog ID=307 and the weight=2. The ALPO/BAA weight=1.
1951 Mar 13 UT 01:35:50 L.T.Johnson (USA) observed a faint flash
near W limb in earthshine - just S of Grimaldi.
ALPO/BAA weight=1.
On 1988 Mar 23 at UT 01:15-01:30 M. Wisniewski (Chicago, IL, USA, S=F)
observed that Aristarchus was the brightest (mag 5), and only feature
visible in Earthshine. It had the appearance of a steady blue-white
star like point. Darling (Sun Praire, WI, USA) though observed other
features as well: Proclus, Theophilus, Cyrillus and Censorinus - all of
which were normal. The cameron 2006 catalog ID=319 and the weight=0.
The ALPO/BAA weight-1.
Sirsalis 1990 Mar 01 UT18:30-19:45 M. Holmes (Rochdale, UK,
21.5cm Newtonian, seeing Antoniadi I/II, Transparency very
good) was observing in earthine and saw an intense blue spot
"wink on" near to Sirsalis (sketch shows location on SE rim),
until clouded out at 18:30. When the sky cleared at 19:15UT
the spot was still visible but fainter, with a halo, the size
of Sirsalis A. By 19:35 there was a loss of detail, region
only a faint patch of light covering area twice the size of
Sirsalis crater. Clouded out permanently at 19:45UT. Cameron
2006 catalog event #392, weight=0. ALPO/BAA weight=3.
A German observer by the pseudonym of "R" on 1883 Nov 05 UT 18:00 saw
Aristarchus as a vry bright 7-8th magnitude star in the dark part of
the Moon. The Cameron 1978 catalog assigns this event an ID of 240 and
a weight of 3. The ALPO/BAA weight is 1.
Proclus 2020 Dec 20 UT 19:40 (T.Smith, Codnor, UK, 16"
Newtonian, seeing III-IV) observed visually and noted that
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.
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.
Theophiuls 2020 Dec 20 UT 19:00 (T.Smith, Codnor, UK, 16"
Newtonian, seeing III-IV) observed visually that the central
peak of this crater appeared excessively/abnormally bright to
his eyes. ALPO/BAA weight=1.
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
flashes a few hours earlier - near Aristarchus. One BAA member, Madej,
had seen a green glow in Arisarchus in two places in two eyepieces.

On 1985 Oct 11 at UT 04:56-05:12 D. Louderback (South Bend, WA, USA,
4" refractor, x95, seeing=1-2-1 and transparency=4) detected a change
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

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,

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.
Proclus 1967 Apr 18 UTC 18:40-18:45 Observed by Farrant (Cambridge,

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

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 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

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.

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.

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

Aristarchus 1975 May 23 P.W. Foley (Wilmington, UK, 12"
reflector, x200, x360, x624, atmospheric clarity good, seeing
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

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,
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.

increased in brightness from then on" Cameron thinks this is just the
edge of the shadow and possibly normal. Cameron 1978 catalog ID=268 and
weight=0. ALPO/BAA weight=1.

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
