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.

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

Theophilus 1978 Nov 08 UT 20:49-22:00 Observed by J.D. Cook
(Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV)
Orange discolouration seen on ESE crater floor. Moon blink
tried, but no blink detected. By 21:10 the effect had lessened,
but was still orange. By 21:50-21:58 the effect was smaller and
perhaps more on the SE of the floor. Colour confirmed by Foley.
Fitton may also have been observing. At 22:00 A.C. Cook observed
and commented that a darkish, perhaps brown-orange colour seen -
but suspected it was probably spurious colour - but by now the
seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of
several features, including Theophilus, had not noticed anything
unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect
a blink, but noticed intermittent darkining on the shaded area
on the E. floor, but seeing was now IV. The darkening was more
noticeable in blue than red light. BAA Lunar Section

On 1975 Apr 19 UT 21:09 P. Foley (Kent, UK), detected blue in
Plato on east. Fiton at UT20:45 found blue along the south wall
at the east (IAU?) end, which was very bright white. Blueness
extended towards the large landslip at the east of the formation.
Immediately north of the landslip, where the bright wall curves
first westwards, then again northwards, red could be faintly
detected, folloowed by a very faint blue. All other parts of the
formation were normal. Examination with a Moon blink device
revealed no colour blink. J-H Robinson also found blue, with red
on the west wall (exterior?). By 21:30UT Fitton found Plato to be
normal and so was Proclus, though he did find Epigenes (bright
cresecent of east wall only) slightly blue to the N.W and red
to the S.E. Mare Crisium was normal. Prominent spurious colour
seen on Venus, but it was low in the sky, with blue to the north
and red to the south. However J.H. Reading, managed to see the
north east floor blurred and slightly blue from 22:45-23:00UT.

On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector,
seeing II-III) noted that the south wall of Plato at the 11 o'clock
position, at the location of a cleft, was fuzzy on either side of the
cleft. There was also a deep red colour along the cleft and the outside
wall. The colour had gone by 22:40 though. All other parts of the rim
of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III)
sketched some obscurations at 22:03UT. At 22:08UT the red colour
reduced to a red line and vanished by 22:37. The south wall obscuration
varied in size and there was a possible obscuration at the 7 o'clock
position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and
M.Cook's observations. Detail inside the crater was sharp, but colour
oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km
away had atmospheric ripples affecting his observations. At 21:36UT G.
North described the south wall as odd in appearance and the terrain
south of this was lacking in detail - this was odd because elsewhere
Plato was nice and sharp. At 21:45UT though the north section of the
crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5.

On 2013 Apr 22 UT 01:39-02:37 P. Zeller (Indianapollis, USA,
10" f/4 reflector, x200, seeing 6, Transparency 3 - scattered
cirrus) observed visually (depicted in sketch) the two closely
spaced NW wall dark bands) to have a rusty-red hue. The colour
of these bands did not change over the period of the observing
session. Images were taken, but resolution and image S/N is
not sufficient to resolve separate bands here, or to detect
colour. The ALPO/BAA weight=1.
On 1981 Aug 11 at UT21:05-21:36 G. North (England, seeing=poor)
detected, in green light, a darkening on the floor of Plato. This
effect was not seen elsewhere. J-H Robinson (Teighmouth, Devon, UK)
detected on the SSE rim (inner and beyond) a triangle that appeared
hazy in a wide range of filters at 21:05UT. However at 21:36UT it was

observer seeing varied from III-V. North (UK, 18.25" reflector)
reported "Colouration and floor craterlets very prominent. Seeing
Antoniadi V, Transparancy Poor.". Foley (Kent, UK, 12" reflector
seeing=III-IV) found the floor to be bright and in the better moment of
seeing detected floor craterlets. The WNW spot was misty some of the
time. Moore (Selsey, UK, 15" reflector, seeing V) had very poor seing
conditions. J.D. Cook and M.C. Cook (Frimley, UK, 3.6" reflector,

On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector,
x300) using an English Moonblink device found colour on the south west
part of the floor. Note that for the times given by Cameron, the Moon
was below the horizon from California - so possibly these are local
times and these times need to be correctly converted into UT? The

brighter in red than in blue light, however the effect faded during
21:29-21:41UT and was gone by 22:40UT. There was however spurious
colour on the north west wall. M. Cook (Frimley, UK) found the central
peak to be both bright and diffuse, and brighter in red than in blue
light during 20:52-20:57UT, however at "22:53-23:58 c.p. very bright &
previous area decreased in size. No detail in white or red, just
visible in blue. Sketch (J. Cook) Orange out on NW rim & on NW side of

On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector,
seeing=III) found the region around the cleft on the souther rim to be
out of focus - however atmospheric conditions were turbulent until
23:18UT. An unsual dark triangular region (long base against rim) was
seen to extend from the inner rim at 12 o'clock onto the floor for 13-
16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK)
found the south east to soth west to be obscured again, but not as
badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the
dark region had 2 white bands on the side and the south west wall was
blurred like it was on the 20th July - this time tough colour was not
present. There were also two light patches on the floor. Mosely
(Coventry, UK) observed the south wall at x120 and found the wall out
of focus at the 11 o'clock location. Through a yellow filter he saw a
"white mistiness: on the top of the southern rim and only the south
east cleft could be seen (no colour). By 22:40-23:00 the effect had
cleared up. No dark triangular patch was seen. When Marshall (Surrey,
UK) observed (22:30-03:00) nothing unsual was seen, though a sketch
provided shows a light patch on the floor located at 11 o'clock. All
observations, made by all observers had some atmospheric turbulence,

On 1975 Apr 23 at UT 20:30 J-H Robinson (Teighmouth, Devon, UK, 260mm
reflector, x200). Observer was observing since 20:30UT, at 21:00UT
though they noticed red on the outside south wall of Aristarchus, a
hazy ill defined area that was larger in a red filter than in blue
filter, and outside east wall was bright in red. At 21:08UT the outside
west wall of Aristarchus no longer gave a colour blink reaction, and at
21:22UT the colour blink on the southern end of the crater ceased, but
the image blur remained (in both red and blue filters) despite the rest
of the crater being sharp in detail. Observations ceased at UT 21:35
because the blurring at the southern end seemed to be normal and this
was confirmed when checked with photographic atlases. Other craters
such as Proclus, Pickering, Tycho, Gassendi, Copernicus, Alphonsus,
Plato, Menelaus, Manilius, Linne and Theophilus, showed no colour blink
reactions. However Picard had a red bright blink from 20:30-20:40 and
the permanant blink on the N. Floor of Fracastorius was detectable.
Also Plato floor shadings were clearer in red than in blue -
intermittently. This is a BAA lunar section observation. No estimation
of transparency or seeing is given, nor any comment on whether spurious
colour was seen in any craters visually. ALPO/BAA weight=1.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi
III seeing, 12.5" reflector) "Intensely bright craterlet south of central
peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed
the crater was highly luminous at 21:20, and surrounded by a blue halo that
had a darker blue band within it. This craterlet faded over time, and by 21:20
Moore considered that it was no longer prominent, by 21:22 Foley confirmed the
reduced brilliance, and by 21:30 Moore considered it to be perfectly normal.
Moore considers the nimbus effect to be normal. The Cameron 2006 catalog ID=
306 and weight=5. The ALPO/BAA catalog weight=3.
On 1980 Sep 22 at UT05:00? D. Louderback (South Bend, WA, USA, 8"
reflector, x140 and 2.5" refractor) observed in Promitorium Agarum that
one of his pre-designated points, called "A", through to "C and "D" was
at least 5 brightness points brighter in red than in blue light. The
reverse was true on Sep 25th. Tonight the red seemed to be on a narrow
strip on the western edge. The Cameron 2006 catalog ID=109 and the
weight=3. The ALPO/BAA weight=3.
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.
Aristarchus 1972 May 25 UT 19:32-19:38 Observed by Leitzinger (8.75E,
48.75N, Germany, 60mm f/15 telescope T=2, S=2) "Bright point at SE wall
well visible, colour changed to orange shortly before it disappeared"
published in Hilbrecht & Kuveler (1984) Moon and Planets, Vol 30, p53-61.
On 1963 Nov 28 at UT 22:30-00:00 Fisher (Colefax, CA, USA, 8"
Newtonian reflector)observed a yellow on crater rims adjacent to
Anaximander. Yellow colour also seen on Aristarchus that night.
The ALPO/BAA weight=1.
Eratosthenes 1936 May 04 UT 05:40 Observed by E.P.Martz
(Mandeville, Jamaica) "Detected bright spots on floor" NASA
catalog weight=3 (average). NASA catalog ID #414. Ref. Haas, W.
1942, J.Royal.Ast. Soc. Canada, 36, 398. ALPO/BAA weight=1.
Aristarchus and Cobra Head 1966 Oct 27 UTC 02:30-03:00 Observed by
Delano (New Bedford, Massachusetts, USA, 12.5" reflector, x360) and
Corralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moonblink).
"C.p. of Aris. noticeably less bright thro blue filter but very bright
thru red & no filter. Shadow of c.p. faint & grayish whereas wall shad.
were normal black. (confirm. of Gordon, even tho 2h later?). Sketch.
C.p. rated 10deg in red & no filter, & 8deg in blue. Other features
rated same in all 3. Cobra Head had 2 red patches. Sketches. Not
confirmed by Corralitos MB." NASA catalog weight=5. NASA catalog ID
989.
Aristarchus 1973 Feb 15 UTC 17:07-19:31 Observed by Theiss (51N, 9.67E,
75mm refractor) "Area 4-5 diameters of Aristarchus were coloured
clearly yellow to red" Ref: Hilbrecht & Kuveler (1984) Moon & Planets
30, pp53-61.
Gassendi 1972 Feb 27 UT 23:15-00:10 Observed by A.Kemp (Cheshire,
UK, 8.5" reflector x286) "Suspicion of blink between Gass. c.p. &
Gass A. Clouds prevented confirm. Hedley-Robinson didn't see
anything unusual earlier (20:00-20:20)." Note that the duration
of the event, or indeed precise UT at which it was seen is not
given. NASA catalog weight=1. NASA catalog ID #1324. ALPO/BAA
weight=1.
On 1994 Apr 24 UT08:15 A.T. Brakel (ACT, Australia) noticed that
Mare Frigoris appeared darker than the day before. This was
during a Clementine watch. The ALPO/BAA weight=1.
On 1985 Sep 27 at UT 20:55 M. Mobberley (Suffolk, UK) found that the
brightness of Torricelli B varied and starlike points seen in the
crater. There is no Cameron 2006 catalog entry for this TLP report. The
ALPO/BAA weight=2.
