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.
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 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.
Aristarchus 1976 Oct 18 UT 07:42 Observed by Bartlett (Baltimore, MD,

advancing shadow a very faint but definite red glow was seen. It was
also seen later in the 3" refr. Was confined to W.base of peak & no
color on E. base tho. carefully searched for. This red glow was unique
in his experience of 28 yrs. His obs. thru. col. 223deg saw nothing

On 1993 May 28 at UT 21:02-21:30 M.C. Cook (Frimley, UK, 3.3" Questar
telescope, x80-x130, atmosphere hazey - poor transparency) noticed that
the east side rims were slightly fuzzy and suspects that this might
have been due to the illumination angle. A.C. Cook (Frimley, UK)
obtained some CCD images that revealed that the effect was to some
extent still there one hour later. The Cameron 2006 catalog ID=461 and
the weight=5. The ALPO/BAA weight=2.
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

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.

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.

On 1997 Oct 13 at UT11:09-11:21 D. Rodway (Oamaru, South Island, New
Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in
the south east corner interior of the crater Aristarchus. This colour
was confirmed by the observers wife. By 11:21 UT the colour had faded
completely. Rodway had been a lunar observer since 1958, using a wide
range of instruments from 3 inch refractors to 12 inch reflectors and
had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so
was an experienced observer. The ALPO/BAA weight=4.
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 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector,

On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar
telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a
dusky dark gray area just north of Herodotus and just south of the
Cobra Head. The interior shadow on the east of Herodotus by comparison
wad black and distinct. No change was seen when viewed through a
rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA)
was observing at the same time but had better observing conditions and
could see detail in this region, suggesting that it was not a TLP.
There is no Cameron entry for this report. The ALPO/BAA weight=1.

Antionadi III, Transparency Moderate) - Colouration Seen - Ref: BAA
Lunar Section Circular. ALPO/BAA weight=2.
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
ALPO/BAA weight=1.
Gassendi 1961 Aug 25 UTC 01:00-02:00 Observed by Cameron (Adelphi, MD,
USA, 3.5" reflector x160) "Crater had a capital gamma-shaped string of
star-like pts. (only abnormal thing noted)." NASA catalog weight=1

On 1979 Oct 04 at UT21:05-23:40 P.W. Foley (Kent, UK, 12" reflector,
x360, seeing=II) detected colour in Aristarchus (and also in Bullialdus
- there was a TLP alert at this time for Bullialdus) but nowehere else
on the Moon. Aristarchus had a CED brightness value of 3.8 at 21:05
(though at this time no colour) and 3.4 at 23:40 and the floor was now
slate blue/gray in colour. Other features remained constant in
brightness. The Cameron 2006 catalog ID=72 and the weight=0. 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
checked. the cameron 2006 catalog ID=322 and the weight=3. THe ALPO/BAA
weight=2.
On 1992 Jan 18 at UT 22:34-23:48 A.C. Cook (Frimley, UK, 8" reflector,
seeing=III) was able to see 4 craterlets and two rays on the floor of
Plato. This was suprising because Moore, using a larger telescope and
magnification, was unable to see any detail here on 1991 Dec 12th at
02:10 - according to Cameron. The Cameron 2006 catalog ID=438 and the
weight=2. The ALPO/BAA weight=1.

reflector, x200, Wratten 25 and 44A filters, seeing II-III,
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
observation. The ALPO/BAA weight=1.

and 3 others, using the same instrument, saw a bright purple-
blue patch in Aristarchus. Other areas checked for colour and
none sen elsewhere. Attempts were made to contact observers
elsewhere but with no success. Sketch made and shows the patch
covering the floor area of Aristarchus and extending out beyond
the east rim. Patch was elliptical in shape and the semi-major

On 1975 Nov 18 at UT 19:38-23:34 Moore (Johannesburg, South Africa, 2"
refractor, S=II), Peters (Kent, UK, 8.5" reflector, x120, S=IV), Good
(Guilford, UK, binoculars), Foley (Dartford, Kent, UK, 12" reflector
and photographs), and McKay (Kingston, England, UK, 6" reflector, x48)
observed the following in Aristarchus during a lunar eclipse: "It
appeared much fainter than ever before seen in ecl. by Moore. Fainter
than Proc., Cop., & Tycho. Others rated brightness in order-- Hell,
Stevinus, Furnerius, proc.; & Proc., Tycho, Hell, Aris. Photos
confirmed dimness of it. For some observers it became invis. at S=II
(good). Good ranked at least 4 other craters brighter than Aris. & that
at 2035h it dimmed. Earthshine cond. extraordinarily good. Peters, at
S=IV (fair?) rated Aris. brightest". At 23:50UT LeCroy Jr and Sr
(Springfield, VA, 4.5" reflector, S=7) observed four glowing spots on
the Moon during a lunar eclipse (including Aristarchus). At 23:50UT
Aristarchus was an oval shape with no details seen. It had a ray
extending from the south west rim (normal). The north rim was slightly
blue and the south west rim very very slightly red. At 23:55UT it was
clearing and details showed. At 00:02UT it was clear. Sketches were
provided. Cameron comments that the colours fit Fitton's predictions on
spectral dispersion in our atmosphere from atmospheric inversions. The
brightness measued was 10+ and normal should be 9, and the plain is
4.5. The Moon's altitude at the LeCroy site was 45 deg. The Cameron
1978 catalog ID=1418-1420 and weight=5 (1-0 for LeCroy report). The
ALPO/BAA weight=3.
Aristarchus 1974 Jan 08/09 UT i18:15-00:00 Observed by
Billington (England), Robinson (Devon, England), Amery (REading,
England), Moore (Selsey, England) "Orange & viol. hue in crater
seen by Billington. Robinson, Amery & Moore reported neg. blink
results at this time. (Prob. chrom. aberr., Moore concurs)."
NASA catalog weight=0. NASA catalog ID #1386. ALPO/BAA weight=1.
On 1989 Aug 17 at UT 01:02-04:20 G. Kolvos (Thesaloniki, Greece,
4"reflector) measured (using photometry) that although there was a
gradual fade over the Moon as the eclipse progressed, there was a 2"%
rise in brightness of Aristarchus.Graphs were submitted and photos.
A.C. Cook supplied CCD images and CCD photometry. A photograph by
Conway (Sun Prarie, WI, USA) at the start of the eclipse reveal a
bright colourless spot (aparently confirmed). The Cameron 2006 catalog
ID=373 and weight=5. The ALPO/BAA weight=2.
On 1893 Sep 25 at UT 21:00? Gaboreau (Paris, France), saw a shaft
of light projecting from the Moon. Cameron 1978 catalog ID=281
and weight=0. ALPO/BAA weight=1.
Aristarchus 1966 Oct 30 UTC 01:32-01:48 Observed by Bartlett
(Baltimore, MD, USA, 5" reflector x79, x142, x194, S=5, T=3) "S.region
of floor granulated & 6 deg bright light brownish tone; rest of crater
8deg bright white". NASA catalog weight=4 (good). NASA catalog ID #992.
On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by N. Hazel
(Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max,
with 2x teleconverter, at f9, 1/320 sec, ISO 400 – tripod
mounted, mirror up), A series of images were taken. The 21:06 one
showed a grey column cutting across the central floor of the
crater from the west and then bisecting the eastern rim. All
detail inside is completely invisble. Some (but not all) of the
other images showed a more blurred view of this feature. It's
possible that this was a seeing ripple effect, or just the
natural appearance of shadings on the Moon at this time, however
for now this will be given an ALPO/BAA weight of 1.
On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade
2045 reflector, x40, seeing=turbulent) detected flashes coming from
just north of the centre of Mare Tranquilitatis. Some of these flashes
were of a duration of seconds whilst others were several minutes.
Altogether ~20 flashes were seen, and not in the same place. "5 small
star-like points could be located - and there were lots of craterlets".
The spots were "lined up E-W at N of 10 deg latitude." Colour was not
visible on these nor variations. Apparently the observer had seen this
type of TLP before but had not reported them. The Cameron 2006 catalog
ID=323 and weight=2. the ALPO/BAA weight=2.
On 1970 Aug 12 at UT21:00? an unknown observer commented about Plato:
"Light #22, remarkable increase in brightness. #32 subsided & #14 shone
out then faded & #16 brightened. (Fort says that till Apr. 1871 selenog
recorded 1600 obs. of fluctuations of lights in Plato & had drawn 37
graphs of indiv. lights. These were deposited in the library of the
Royal Astronomical Society by Birt)." The Cameron 1978 catalog ID=169
and the weight=3. The ALPO/BAA weight=2.
On 1992 Jan 20/21 at UT 23:49-00:15 M.C. Cook (Frimley, UK, 3" Questar
telescope, x130, seeing=III) managed to see the central craterlet in
Plato and an unnamed one north west of Mons Pico. Cameron comments -
"were this & No. 429 LTP or just good seeing?)." Note it is possible
that she mean LTP 439 in which case it would refer to the previous
nights TLP. The Cameron 2006 catalog ID=439 and the weight=2. The
ALPO/BAA weight=1.
Mare Crisium 1965 Oct 11 UTC 10:10 Observed by McCord (Mt Wilson, CA,

On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector,
x260) saw at 01:25UT an unmistakable red-orange glow on the south and
south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected
it easily. At 01:33UT the colour was barely visible. No TLP alert was
issued because the souther edge of Mons Pico also exhibited a hint of
colour, and anyway the seeing conditions were poor. Despite this no
other features revealed colour. The Cameron 2006 catalog ID=446 and the
weight=0. The ALPO/BAA weight=1.
On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector,

On 1984 Nov 10 at UT19:15-19:50 R. Moseley (Coventry, UK, the Moon's
altitude was low) noticed that the region from the central peak and
over and onto the east wall looked unusual. 8 bands were visible, "two
on E. wall of c.p. strongest, surrounding collar grey increasing
intensely outward. Band at 2 o'clock position was very dark. Bright
spot on W. wall at 4 o'clock position." A sketch was made that
illustrates bands on either side with bright patch. The Cameron 2006
catalog ID=252 and the weight=2. The ALPO/BAA weight=2.
On 1988 Jul 31 at UT 07:09-08:10 D. Darling (Sun Prairie, WI, USA,

the south east floor of Proclus (the TLP from a few days earlier), but
did see 2 "linear mounds". The Cameron 2006 catalog ID=335 and the
weight=0. The ALPO/BAA weight=1.
On 2011 Jan 21 at 22:30UT N.Longshaw (UK, 4" Achromatic
refractor, x128 & x160, Seeing III, transparancy average)
suspected on the eastern edge of Geminus, on the border of the
crater filled shadow and the eastern illuminated rim, a
brownish, almost speia hue. This extended for a short distance
from the floor shadow into the illuminated rim width and spanned
from the north to the south of the crater. For a comparison,
Cleomedes was checked but nothing unusual was noticed in its
shadow. The observer notes that Elger also saw a warm brown or
sepia tone. ALPO/BAA weight=1.
Lictenberg Area 1940 Oct 19 UT 07:11 Observed by Barcroft
(Madera, CA, 6" reflector) Pronounced reddish-brown or orange
