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 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st
7:24PM PST) saw a naked eye flash on the Moon. The observers were
glancing up at the Moon in daylight when they saw a bright white flash
(observer and his wife together) in the upper/mid Mare Serenitatis
region, west of the crater Posidonius. "Larger than how Venus appears".
"It was a quick flash like white, intense lightning. I'm not sure how
to report degrees of arc but if the face we see is 900, and we start
from the east then the flash occurred about 225 arc seconds to the
west. This was observed by the naked eye, with clear skies between us
and the moon." The observers checked for signs of aircraft vapour
trails but could not see any. There is a possibility that it could have
been sun glint from an Iridium satellite, but this needs to be checked
out and usually these last longer than the observed effect. It would be
useful to obtain whole Moon images under the same illunination and
libration so that we can judge this observation properly. The ALPO/BAA
weight=4.
Herodotus 1965 Jun 11 UTC 21:35-21:40 Observed by Porta, Garau

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

Ptolemeus 2020 Jul 27 UT 23:00 N. Travnik (Brazil) observed
visually for 2nd time ever (first seen back in 1970), an
effect on the floor of this crater at local lunar sunrise:
"kind of glimmering mist lifted and wafted inside the shady
hollow of the crater". Almost certainly this is a combination
of atmopsheric seeing on the narrow shadow spires, but we
would like observers to look at this visually or obtain time
sequence images to try to replicate this effect. This report
is assigned an ALPO/BAA weight of 1 for now.

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 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
only hazy in green and blue light. No similar effect was seen
elsewhere. The Cameron 2006 catalog ID=150 and weight=5. The ALPO/BAA

location 54.53W, 23.5N. It had a duration of 0.5 sec and on a
brightness scale of 0 = night side of the Moon to 10 =
Aristarchus, ranked 7. Unfortunately they were not recording
at the time. As there was no confirmation observation and it
could be a cosmic ray air shower detection, the ALPO/BAA
weight=1
In 1934 Feb 25 at UT 18:30 Rawstron (USA?, 4" refractor, x250, S=6/12)

Curtis, Keyes, Yanna, Norman, Knutson, Sullivan, Eichman and Radi (Carl
Fosmark Jr. Memorial Observatory, Madison, WI, USA, SCT C11) "Manske
initially observed a reddish tinge on the SE rim of Aristarchus. The
colour was present in different eyepieces. Two other pinkish tinge
areas were seen on the SE and NE rims. 4 of the observers did not see
colour. Independent confirmation was made by Don Spain (KY) and Smith

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,
however trsnparency was good. The Cameron 2006 catalog ID=225 and the
weight=5. The ALPO/BAA weight=3.
On 1992 May 13 at UT 20:16-21:29 several observers reported a TLP in
Plato mostly concerning the visibility of floor craterlets, however
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,
seeing II-III) used a CCD camera at 22:11 UT. The Cameron 2006 catalog

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
Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.
On 1980 Dec 18 at UT20:46-23:58 A.C. Cook (Frimley, UK, 12" reflector,
40-250x, S=IV and transparency good) found the north west wall to be
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

Dungan (Flagstaff, AZ, USA, 24" refractor, and 69" reflector)
observed pink on the outer SW rim and a red spot towards the S of
this. A red spot was seen on the eastern side of Vallis Schroteri
but only by Barr and Dungan. Other features checked for
atmospheric spectral dispersion and chromatic aberation - but the
colours in Aristarchus were not due to these. Smaller 12" scope
checked but no effects seen - presumably due to resolution and
image contrast issues? Pink on the SW rim may have been seen in a
69" scope by Boyce and Ford. ALPO/BAA weight=4.

3.0. The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
In 1962 Dec 09 at UT 07:36 Wildey and Pohn (Mt Wilson, CA, USA, 60"
reflector) observed that Oceanus Procellarum was 1.13 magnitudes
brighter than normal. Observation at sunrise and is abnormal if area
measured was mare. If it were an east facing wall it would be normal.
The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
Aristarchus-Herodotus 1970 Apr 18 UT 20:14 Observed by MacKenzie
(UK,2.5" refractor x45, seeing Antoniadi I) "Fairly strong blink
in a spot 1/2 way between the 2 craters. Drawing (Apollo 13
watch). NASA catalog weight=2. NASA catalog ID #1257. ALPO/BAA
weight=2.
On 1992 Feb 16 at UT 01:05-01:35 P. Moore (Selsey, UK, 12.5"
reflector, seeing=III) found the north rim area to be both very
bright and misty - though he did not think it to be a TLP but
wanted it to be recorded, just in case. The Cameron 2006 catalog
ID=440 and the weight=1. The ALPO/BAA weight=2.
Torricelli B 2002 Oct 18 UTC 20:56-21:59 Observer: G.North (UK, 8"
reflector, x134, Seeing Antoniadi IV, Transparency good) - thought that
Torricelli B was perhaps a little brighter than expected, especially
when compared to Moltke and Censorinus based upon past recollection of
relative brightnesses at this colongitude). Slight bluish tint seen as
well. The ALPO/BAA weight=1.
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
