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 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.

On 1983 Dec 17 at UT 17:25-19:20 Moseley (Covington, England, UK, x120
and x240, seeing=III and spurious colour present) found that the inside
of Aristarchus crater was dull and slightly blue. Suspected the colour
to be spurious: at 19:20 at x240 the colour was pink but at x120 there
was no colour. Cameron 2006 catalof ID=234 and weight=3. ALPO/BAA

On 1915 Jul 24 at UT 22:00? Barabashovihi (Russia) observed a TLP on
the west limb: "When phi Strettsa (?) approached the edge but still
separated, the star began to stretch in a belt 3X its own length & then
instantly disappeared. Probably no significant atm. or vapors. (similar

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.

the weight assigned is 5. ALPO/BAA weight=1.
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

On 1977 Apr 02 at UT22:00-00:00 L. Fitton (Shaw, Lancashire, UK, 8.5"
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.
Moretus? 1871 Dec 25 UTC 22:00? Observed by Webb? (England?, 9"

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.

During an eclipse of the Moon the crater appeared normal until it
emerged from the shadow. In the north east the dark floor was
not its normal hue and two light areas appeared to join. The

reflector, x110, x200 & x274, S=8-8.5, T=8, Moon 57 deg in alt)
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

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

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

On 1898 Jan 08 at UT 00:00-01:00 Chrevremont (France?) notcied that
during a lunar eclipse, the mid-eclipse shadow was so dark that details
of the surface disappeared, all except for the Tycho SSW ray . Cameron
comments that it is unsual for that ray to remain when usually the ones
towards Kepler and Aristarchus are the ones to stand out? The Cameron

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

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

Proclus C region 1985 May 23 UT 17:41 Photographed by Kolovos (observer
from Thessoloniki, Greece, observing site near Bafra Serrain, Greece,
4"refractor, seeing excellent) "Observer took a series of expousres on
a portable scope of the Moon. On one of them a very bright slightly
elliptical spot was seen. Spot was very close to the Proclus C crater.
Upon analysis it was claimed that the spot of light had rotated the
direction of illumination of shadows in adjacent craters - however
subsequent analysis casts doubt on this. Papers on this report
were published in Icarus. Rast and Maley suggested that it was sun
glint off a spinning US ex-military weather satellite that just by
chance came across the field of view of the Moon a few tens of seconds
around the time of the photographed flash. Was this a coincidence or
not? If it were a satellite sun-glint then the satellite would have to
be tumbling incredibly fast in order for the flash to be so sharp in
the photograph - so the satellite explanation is not completely 100%
confirmed." The Cameron 2006 catalog ID=273 and the weight=5. The

On 2009 Mar 01 at UT 18:50-21:00 G. Smith (East Yorkshire, UK, 127mm
Maksutov Cassegrain telescope with zoom eyepiece and later a Plossl
eyepiece) observed an area between Plato and Sinus Iridum to be glowing
as a bright nebulous patch. It was brighter than anything else in
Eartshine. A change in eyepiece did not affect the appearance of the
nebulous patch. The patch had faded somewhat by 21:00UT. The observers
brother attempted to observe the patch through a 114mm reflector at
20:30UT but the optics were of poor quality and the effect was not
seen. BAA observers were alerted, but only after the event had faded -
they made observations from 22:00-23:46 UT but failed to detect
anything unusual in the region concerned. The ALPO/BAA weight=1.
This may have been a mis-identification with Aristarchus - however
we cannot be 100% sure.

4.5" and 8" reflector, seeing=excellent), Albert (CA, 8" reflector,
x375) and Emanuel (8" reflector) observed star-like flashes in
Aristarchus crater. Cameron says this confirmed and that the date
in MBMW is 7/3/65 which is local time = 4th UT also but is in error due
to misreading of handwriting. The Cameron 1978 catalog ID=883 and

On 1984 Jul 04 at UT 22:05-23:09 Richardson (Swinton, Yorkshire, UK,
seeing=VE) found that a peak west of Theophilus crater had a deep blue
colour, and this was strange because no colour was seen elsewhere on
the Moon. Foley (Kent, UK, 12" reflector), once alerted, found a dome
east of Kant? to be blue, and likewise no colour was seen elsewhere on
the Moon. Cameron 2006 catalog ID=246 and the weight=4. The ALPO/BAA

Censorinus 1984 Jul 05 UT 21:05-21:25 Observed by Cook (24" reflector
with line scan photodiode array at Mill Hill observatory, London) "Two
line scan photodiode array images were taken which used the motion of
the Moon to build up an image. The first image at 21:25UT did not
include all of Censorinus, but the part that it did include was not
very bright. The 21:25UT image did include all of Censorinus and the
crater was bright, including the part that was just visible in the
previous image. Possibly the seeing was worse at 21:05? and this could
explain the brightness descrepency, but it is worth checking again by
taking images at the same illumination conditions" BAA Lunar Section
report. At 21:17 M. Cook (Frimley, UK) found Proclus to be brighter
than Censorinus (more so than the previous night) and obtained variable

observed a strong beacon like flash in white light that moved back and
forth in the east wall of Plato (very bright) and Mons Pico. tried
changing eyepiece and the field of view, but this wasn't the cause of
the effect. A check at 11:07UT did not show the effect, but it was back

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

A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and
definition fairly good. Observer noticed that the Mare seemed covered
with a close network of innumerable streaks, and spotted with countless
numbers of light specks, so that it would hardly be possible to
delineate them all in one night. The spots and streaks together must
have numbered ~1000. The observer had never seen anything like the

On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector)
and at the same time Doherty (Sussex, UK, 15" reflector) observed a
strangely bright and pink/red north rim of Aristarchus crater during
UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT.
M.C. Cook (Frimley, UK) found the northern wall to have a red/purple
colour but the effect vanished after 50 minutes. Cook also saw a "V"-
like notch in the NW crater shadow and this appeared to be bigger than
normal. G. North (Sussex, UK) saw a tinge of pink colour on the
northern rim and a bit later a "ruby red" colour on the north-west wall
- again this effect lasted 50 minutes. Moseley verified the colour.
Finally M. Hather (Yorkshire, UK) suspected the north wall of
Aristarchus to be blue in colour. Cameron suspects that this TLP is not
spurious colour because it is in the wrong place. The Cameron 2006

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
weight=3.
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
ALPO/BAA weight=1.
Proclus 1990 Mar 09 UT 00:12-00:13 Observed by Marie Cook (Frimley, UK,
3.5" Questar telescope) observed a "long plume of light" the brightness
was the same as the wall region. It went from the southern rim about
half of the way across to the centre in the "northerly". The plume
feature was not seen at higher magnifications. Change in brightness
also noted. The Cameron 2006 catalog ID=394 and the weight=1. The
ALPO/BAA weight=1.
On 1994 Apr 23 at UT02:41 D. Fryback (Madison, WI, USA) observed a
starlike flash in Alphonsus crater. The ALPO/BAA weight=2.
On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit
around the Moon, obtained images of the Cobra Head region of
Aristarchus crater that suggested a ~15x colour ratio increase (0.4
microns / 1.0 microns) in comparison with images obtained on 1994 Mar
03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting.
However it was later suggested that this was due to incorrect
radimetric calibration procedures being followed. The ALPO/BAA
weight=1.
Herodotus 1998 Dec 30 UT 18:50-19:10 observed by J.Knott
(Liverpool, UK 22cm Newtonian, x216, seeing II, transparency
good). Observer reports a bright spot, as bright as the
central peak in Aristarchus on the NW rim of Herodotus at
19:10 (still there at 19:15, but the curious thing was that it
was not visible earlier at 18:50? Now there is a bright
craterlet here, and the observer doubted if what he had seen
was unusual - though we have the rise in brightness o20
minutes to account for? The ALPO/BAA weight=1.

very bright. However the colul had gone by 20:29UT. "Varied in albedo
2s then image blurred at 5-10s (atm) at 2034 became pink). At 21:35UT
M. Mobberley (Suffolk, UK) found a white patch in the crater centre and
a mag 8 flash was seen (confirmed independently by a 2nd observer ~
113km away)- there was no shadow. At UT 20:30 P.W. Foley (Kent, UK,
12"reflector, seeing excellent) found no colour, but the brightness was
changiong and he confirmed the bright patch on the crater's floor,
variable 22:15-22:25UT, "then expanded over rim". The Cameron 2006
catalog ID=277 and weight=5. the ALPO/BAA weight=4.
Two small conical mountains, near last 4th May eruption,
close to the third one that he had seen before, but not
these two. They were not on any map.

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.
