Seeing = good, altitude=20 deg) observed during an eclipse brilliant
points for 30 minutes in Ross. Cameron says that the date given

On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK,
seeing=IV-V, transparency=good, spurious colour seen) found 2
bright pathces on the east rim on alternate sides of a bright region.
The band from the central 16km wide region was dark on the east side.
Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be
not as bright as normal, apart from the band that Mobberley found (1
hour later). The dark regions were a murky green colour (bright through
green, blue and yellow filters and dark through red and orange
filters). Cook (Frimley, UK, transparency=excellent, CCD camera used)
found a bright "bulge"on the eastern side. Apparently data suggests
that the band was brighter in red than in near IR light. Cook's
calibrated brightness measurements suggest that there was no change in
brightness over the crater with time. Two other bright points were
seen: one at the Cobra's Head and another half way between the east rim
of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87
(near IR) and combined Wratten 29 and Wratten 87 were used. In the red
Wratten 29 filter the brightness falls at22:20 at Shroters valley and
then rises in the bright ray. They return to normal at 22:30UT. There
was however a lot of measurement noise from the brightness readings of
points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The
ALPO/BAA weight=3.
On 2000 Jun 16 UT 20:37 C. Brook (Plymouth, UK, 60mm
refractor, x117 & x40, seeing good, transparency excellent)
observed abright spot on the north rim of Mare Crisium (57E,
25N). It was comparable to the illuminated rim of Proclus in
brightness. No colour seen. The spot was not visible the next
night. The ALPO/BAA weight=1.
F. Graham took some photos of the Cobras Head and found a blue cloud
about 50 km in diameter and scattering light - Cameron says that
this indicates high density. Darling found the Cobra's Head obscure and
variable "clear and bright to diffused". Cameron was alerted observed
(02:40UT) variations with periods of approximately 30 seconds, and
thought that she could see a red tinge on the east rim of Aristarchus -
checks elsewhere found no other colours. Darling found that a blue
filter enhanced the effect and a red filter made it disappear. There
was a blink at 02:55UT but no blink in the Cobra's Head, which looked
fuzzy and lacking in detail. The effect was confirmed by Weier, who
also saw two dark spots in the Cobra Head in blue but not in red light.
The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall
7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south
wall 7.0, East wall 8.0, and the central peak 10.0. Observer details

refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP
in Macrobius. His report is as follows: "Blinked Macrobius with Wratten
Filters Blue 38A and Red 29. Macrobius became almost invisible through
the Blue 38A and essentially the same as in white light through the Red
29. The interior of the crater was completely in shadow. The only part
of the east wall that was visible was an apparent high point still in
the sun and seen as a bright point of light. This faded into darkness
before 13:56UT. No sign of any illumination of the east wall crater
interior or the interior of the west wall was seen during the
observation period. The outer west wall was a rough looking,
complicated mix of deep shadow and illuminated sunlit terrain." The
observer concluded that there was not a TLP - although he did get a
filter reaction, this may have been due to the different densities of
the filters? ALPO/BAA weight=2.
On 1989 Jan 26 at UT 03:45 De Groof (Belgium) noted a white few second

On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3"
refractor) observed that the south floor of Aristarchus was wellow -
"almost gold, spilled over S wall on ray toward Herodotus". Cameron
comments that Bartlett often reported a yellow floor but not a spill of
the colour over to the external ray. Cameron also comments that
Louderback's refractor would refract more in blue light than in yellow,
therefore she did not think that it was due to chromatic aberation. The
Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=2.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3"
refractor) found that all of Mons Piton was "unusually dark". Points D,
C (E and S resp), usually brightest points, but this time were not
bright. "Whole mt was as dark as W wall usually is at this time. In
violet filter Piton disappeared completely, but was a little brighter
in red filter and points D & G showed. Color not seen by eye. No albedo
measured. Suggests red event." Cameron rules out chromatic aberation
from Louderback's refractor. The Cameron 2006 catalog ID=431 and the
weight=3. The ALPO/BAA weight=1.
Plato 1975 Jun 28/29 UT 23:00-01:20. Foley (Wilmington, UK, 12"

"green glow in the "peninsular region" of Cape La Place (south of poss.
Helicon A?) and brown on the Earthlit limb. Foley (Kent, UK, 12"
reflector) noticed a "pin point glow surrounded by blue-green halo"
through a blue filter, but not seen through a red filter. He also
suspected some brightness variations. He noted that Aristarchus was
barely seen and Copernicus was only a faint smudge, presumably because
of the bright limb? J. Cook (Frimley, UK) observed a white glow in the
Cape region (made up of pin points?) - no other places had a similar
effect. P. Moore (Selsey, UK, 12" reflector) reported that nothing
unsual was to be seen anywhere on the Moon. M. Cook (Frimley, UK) found
a "bright point source near the tip of LaPlace perhaps maupertius D (or
LaPlace D?)." This was seen in a blue filter but not through a red
filter - the limb was also seen as bright and the cape as a faint
patch. Holmes (Lancashire, UK, 30"? reflector or refractor?) although
commenting that Aristarchus was a bit dull, could not see the Sinus
Iridum glow, North (UK) could only detect the vague presence of
Earthshine throug his finder scope, but not in his telecope. The
Cameron 2006 catalog ID=349 and the weight=2. The ALPO/BAA weight=3.
On 1989 Feb 10 at UT 18:15-18:40 Holmes and Wooler (Lancashire,
UK, 22cm Newtonian, x155) found Aristarchus to be bright, but so
too was Prinz. However in a 2nd observing session at 21:05-21:10
an area near crater both regions werestill visible but fainter.
The Cameron 2006 catalog ID=350 and weight=3. The ALPO/BAA
weight=1.
On 1977 Sep 17 at 16:30UT V.M. Chernov (Soviet Union) observed the
northern cusp of the Moon to be elongated more than 180deg ashen light.
This was 4.3 days after new Moon. The ALPO/BAA weight=1.
On 1989 Feb 10 at UT 19:00? D. Holmes and Wooler (Lancashire, UK) found
area near Prinz to be bright, but so too was Aristarchus crater. The
Cameron 2006 catalog ID=350 and weight=3. The ALPO/BAA weight=1.
On 1989 Feb 10 at UT 19:00? Edmonds (England) observed a
"bright red coppery" colour in the northwestern part of
Proclus crater. He checked and found that there was no colour
elsewhere, though he still suspects that the effect was
spurious colour. Cameron comments that usually blue
is seen in the north and red in the south if due to spurious
colour. The Cameron 2006 catalog ID=350 and the weight=3. The
ALPO/BAA weight=1.
Theophilus 1955 Jun 25 UTC 20:30 Observed by Firsoff (Somerset, UK,
6.5" reflector, x240) "Blue mist. Both c.p. & ENE (IAU?) ridge appear
misty, slightly blueish & milky -- renders effect perfectly. Absent
next nite". NASA catalog weight= 4 (high). NASA catalog ID #596.
Leibnitz Mountains 1948 Apr 14 UT 20:00? Observed by Wilkins
(Kent, England, 12.5" reflector) " S.cusp prolonged -- detached
peaks -- starlike pts. connected by fine filaments brighter than
earthshine. (Barcroft, Haas, Vaughan, Moore & Firsoff also have
seen similar phenom.)(just sunlight catching high peaks?)." NASA
catalog weight=2. NASA catalog ID #502. ALPO/BAA weight=1.
Posidonius 1968 Apr 03/04 UT 22:29-00:15 Observed by McConnell
(Antrim, N.Ireland, 3.5" refractor, x117, S=E) "Peculiarhaziness
in NE (ast. ?) corner of crater. Greenish-yellow tint similar to
M.Crisium at FM. Central crater was clearly vis. N.wall showed
no detail at all." NASA catalog weight=3. NASA catalog ID #1064.
ALPO/BAA weight=3.
On 1985 Apr 25 at UT 21:34-22:04 H. Miles (England) observed
Aristarchus within Earthshine. Foley (Kent, UK, 12" reflector) had
observed it one hour prior to Miles and found it to be both dull and
blue - with a bright patch west of the crater on Aristarchus Upsilon
Mountain. At 21:45UT 6 star-like flashes seen on the floor. They
occurred again a few minutes later and repeated at 22:04UT.By 21:45UT
the bright patch had gone though. Smith (England) had also apparently
seen the flashes and a further glow, albeit more north of the one seen
by Foley. Miles confirmed Smith's glow north of Aristarchus.
Peters did not see much, indeed found Aristarchus to be quite
faint (2130-2141). The Cameron 2006 catalog ID=264 and the
weight=3. The ALPO/BAA weight=2.
Curious lack of detail, but this may have been related to
the seeing. Of greater interest though was a dark blue
splodge where the crater should have been. Shadow seen through
this splodge, but no crater rim seen.
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.
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 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.
Mobberley and Foley note that Aristarchus was very
prominent in Earhshine. Little other detail seen
in Earthshine other than the limb. The Cameron
2006 extension catalog then says: "Confirm moving
side to side. Saw bright blue spot in center" however
it is unclear whether this refers to Aristarchus,
or Torricelli-B - the latter was also undergoing a TLP
at this time. Cameron 2006 extension catalog ID=267
and weight=5 (confirmed?).
On 1985 Apr 27 UT 22:00 M. Mobberley (Suffolk, UK) could not see much
detail in Earthshine (apart from Aristarchus), except that there was a
brightness on the western limb of the Moon. The Cameron 2006 catalog
ID=267 and the weight=5. The ALPO/BAA weight=1.
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
weight=1.
On 1973 Dec 02 at UT 22:17:33 Barrett and Brick (New York, 3.5" Questar
freflector) observed an occultation of Kappa Aquari, a wide double
star, on the western limb. The star faded perceptably before
disappearing. Cameron says that the fact that the star was a double was
not an explanation - she says that there are many reports of similar
fades for single stars. The Cameron 1978 catalog ID=1384 and weight=4.

On 1981 Aug 09 at UT05:08-05:21 D. Louderback (South Bend, WA, USA, 3"
refractor) found that the bright patch in the southern part of Eimmart,
could only be seen well in red light (this is between A, C and D in his
feature notation) i.e. 5 brightness values higher than in white or blue
light. Indeed in white light this bright area was closer to the east
wall bright spot. The Cameron 2006 catalog ID=149 and weight=4. The

Proclus 1972 Jul 19 UT 21:24-21:30 observed by S.Westmoorland
(Cropwell-Bishop, UK, 15cm reflector, x48 & x96, image dull

prevented further observations. ALPO/BAA weight=1.
On 2001 Jun 29 at UT22:16-22:22 C. Brook (Plymouth, UK, 60mm refractor,
x120, no spurious colour seen, seeing I) observed that the central
peaks of Alphonsus looked bright at 22:16UT but had dimmed by 22:22UT.
The three dark patches on the floor of Alphonsus were clearly seen. The
ALPO/BAA weight=1.
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.
1996 Apr 27 UTC 02:26-03:14 Observed by Spellman (Los Angeles, CA, USA)
" 02:26 U.T. Sunrise on Tycho 3/4 of the crater was in shadow,
topmost section of the central peak was in sunlight. In white light
brightness of the central peak rivaled the brightness of the Eastern
(sunlit) wall. No change was detected in red light, however in blue
light definite strong darkening was observed. Blink obtained when
viewing thru 25A and 38 filters. At 2:52 U.T. in the poor to fair
seeing the apparent size of the central peak in white and red light was
the same, in blue light the central peak in white and red light was the
same, in blue light the central peak size shrank to 1/2 white and red
size (and brightness). Also appearing sharper. Comparison was made also
with the central peak of Alphonsus, no changes were observed. The
significant part of the observation was the relative brightness of the
central peak to the sunlit rim in white and red light, they appeared
almost identical with the crater rim, being just slightly brighter. In
blue light the brightness of the central peak was reduced by at least
half while the rim brightness was not, (relative to one another). I
strongly believe that this was a real event. The shadow filled
portion of Tycho was examined for any abnormalities but none
were observed. Observations were ended shortly after 3:14 U.T. due to
clouds. I also conducted about 20 Moon blink observations during this
observing run and got the same strong reaction each time." ALPO/BAA
weight=3.

reflector) "Invisible (date in MBM) is wrong, would be only 6h before
NM. Sunrise on crater is at 3d & ? h. No interposition of dates works
e.g. 13th or 1926 or Dec 26 1923. Only Dec 3 1927 is feasible as it
would be just after 1st Q. & more similar to the May obs.)" NASA
catalog weight=4? NASA catalog ID #396. ALPO/BAA weight=2.
On 1988 Mar 27/28 UT23:30-00:30 M.C. Cook (Frimley, UK, 12" reflector)
found Censorinus to have a "foggy/fuzzy" appearance that was not seen
in adacent areas. The Cameron 2006 catalog ID=321 and weight=4.
ALPO/BAA weight=2.
On 1988 Mar 27/28 at UT 23:30-00:30? M.C. Cook (Frimley, UK, 12"
reflector) noted that the crater Proclus was bright visibly, but the
CED brightness measurement gave the same brightness as Censorinus
crater. The Cameron 2006 catalog ID=321 and the weight=4. The ALPO/BAA
weight=2.
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
and weight=5. The ALPO/BAA weight=3.
SE of Ross D 1966 Oct 24 UT 03:17 Observed by Cross (Whittier,
CA, USA, 19" reflector, x300, S=3-5, T=3-4) Ross D activity at
level 5. ALPO/NAA weight=1 as it is not mentioned in the Cameron
catalog.
Alphonsus 1966 May 29 UT 21:45-22:45 Observed by Wise (England, 4.5"
reflector, x125). and Corralitos Observatory (NM, USA). "Glint lasting
1.5s. (onset of Smith's anomaly? Specular reflection should last
longer). Not confirmed by Corralitos MB, (however they report Gassendi?
misident., or did they obs. another feature?). At UT 22:45 Smith and
Brown (England, UK, 10" reflector) observed reddish patches in
Alphonsus. Negative results from Brown though at 21:21Ut and 22:25UT).
The Cameron 1978 catalog ID=939 and 940 and weight=4. The ALPO/BAA
weight=3.
On 1984 Jun 09 at UT 04:55-05:14 P. Jean (Outremont, Canada) detected
in the dark side of the Moon, a few km east of Kies crater, a bright
point that should not be poking out of the shadow (according to Foley).
The Cameron 2006 catalog ID=244 and the weight=3. The ALPO/BAA
weight=2.
127mm f/12 GoTo scope, x62-x154, seeing: best and transparency=
6) observed that an unoficially named mountain (Lambert Gamma or
Mons Undest), near Lambert, had a "very strong glow", especially
the part that was facing the line of the terminator and this was
brighter than the side facing away. The No other object nearby
was casting as much light, even Mons La Hire. The effect was
seen for 40 minutes and the glow was present throughout. The
ALPO/BAA weight=2.
On 1974 Jan 03 at UT 18:30 a Norwegian amateur astronomer,
Hoydalsvik (Hakonsgate, in West Norway, 60mm refractor)
photographed the Moon using High Speed Ektacrome (400ASA) film
with good focus. The TLP was located on the southern slope of
Sasserides H and was pink in colour with some bluish in it.
The coloured area was circular with a diameter of 0.5 minutes
of arc. Only one exposure was taken. The photograph was
checked by the Institute of Theoretical Astrophysics,
University of Oslo. Although they thought it was probably
genuine (could have been an impact flash?) suggestions by the
BAA lunar section favoured static electrical discharge on the
film. It is uncertain whether the film was ever examined by a
Photographic developing lab such as Kodak, who would be able
to tell if it was real or an artefact. ALPO/BAA weight=1.
Ross D 1965 Dec 04 UT 04:25 Observed by Cross (Whittier, CA, USA,
19" reflector, x155, seeing 4+) "Obscuration of part of the rim,
also bright area 7-10km diam. Not seen on following nite." NASA
catalog weight=4 (good). NASA catalog ID #917. ALPO/BAA weight=3
Plato and Plato A 1972 Jan 26 UT 18:25-18:55 Observed by Watkons and
Hunt (England, 4.5" reflector x150, x225, and a 2.75" refractor) "Misty
patch over A, & a misty brightness over SW wall of Plato. Hunt saw
nothing unusual." NASA catalog weight=2 (low). NASA catalog ID #1321.

On 1980 Aug 21 at UT20:00 J.H. Robinson (Teighmouth, Devon, UK)
detected colour, using a Moon Blink device, and "mistiness" on the
southern floor of Tycho crater. The seeing was poor! Cameron 2006
catalog ID=104 and weight=1. ALPO/BAA weight=1.
SE of Ross D 1966 Oct 25 UT 03:46 Observed by Cross (Whittier,
CA, USA, 19" reflector, x300, S=2-4 (sometimes 5), T=3-4) "Large
bright area obscuring 1/2 of Ross D crater wall. Not present Oct
24" NASA catalog weight=3 (average). NASA catalog ID 986.
Actually some activity was observed the fay before according to
the original notes. ALPO/NAA weight=2.
Archimedes 1973 Jun 11 UTC 21:05-21:15 observed by Pasternak (53deg
20'N, 7deg 30'E, 75mm reflector) "Faint red area at the E of Archmedes,
diminution from 21.10-21.15UT" - Hilbrecht and Kuveler, Earth, Moon &
Planets, 30 (1984), p53-61
Gassendi 1966 May 30 UT 20:32-20:59 Observed by Sartory (England, 8.5"
reflector + filters) "Orange patch & obscuration -- detected by Eng.
moon blink system. Color seen visually."NASA catalog weight=4 (good).
NASA catalog ID #941.
On 1989 Feb 17 at UT00:55 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x248) found that the brightness of the rim of
Proclus was 9.0, the north west wall to be 9.5, the west wall
to be 5.2, and the east wall 8.2 (normal?). The Cameron 2006
catalog ID=355 and the weight=1. The ALPO/BAA weight=2.
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 1964 Jun 21 at UT 03:43-05:44 Harris, Cross and Helland (Whittier,
CA, USA, 19" reflector) observed south of Ross D: "Moving dark area".
The Cameron 1978 catalog ID=819 and weight=4. The ALPO/BAA weight=4.
Plato 1873 Nov 01 UTC 20:00? Observed by Pratt (England?) "Unusual
Appearance". NASA catalog weight=1 (very low). NASA catalog ID #182.
ALPO/BAA weight=1.
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.
N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red
patches on the floor between 20:54 and 21:31UT. A BAA Lunar Section
report. ALPO/BAA weight=3.
On 1964 Jun 21 at UT 21:18 Lipskii and Pospergelis (Shternberg State
Ast. Institute, AZI-2" reflector (Cass.) observed Aristarchus:
"Polarization meas. with electron polarimeter. Plane of polariz.
rotated 2deg fr. the adjacent areas. They interpret it as some
scattering medium over the crater. (Source gave date as 6/31/64,
misprint =21st?)". The Cameron 1978 catalog ID=820 and weight=5. The
ALPO/BAA weight=4.
Gassendi 1968 Oct 03/04 UT 19:30-19:50 & 00:20-01:40 Observed
by Rawlings (Aylesbury, UK, 6" reflector low magnification)
and by Moore (Selsey, Sussex, UK, 12.5" reflector, x360)
"Slight blink (Eng.) arcuate in shape, N. of c.p. (Rawlings
dubious). Moore, with blink device saw none at 0020-0140h. No
LTP in Gass., Ptol. or Aris. 5th or 6th.". NASA catalog
weight=1. NASA catalog ID #1093. ALPO/BAA weight=1.
On 1980 Aug 22 at UT20:15-21:29 J-H Robinson () detected violet on the
west wall of Aristarchus. Cameron 2006 catalog ID=105 and weight=5.
ALPO/BAA weight=2.
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.
ALPO/BAA weight=4.
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 2017 Sep 02/03 UT 23:55-00:30 A.Anunziato (Parana,
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.
ALPO/BAA weight=1.
On 1825 Jan 01 UT17:00? an unknown Russian observer noticed a
cloud in Mersenius.
nr Fra Mauro 1970 Aug 14 UT 05:00? Observed by Bell (Californina).
"Bright blue-white flare (meteor?)(call for obs. at Fra Mauro at
perigee because of moonquakes there -- therefore biased to tidal
hypothesis. That was the original location given for the A1 moonquake
site, but it is located elsewhere now. Ancill. data given for 1970)."
NASA catalog weight=1. NASA catalog ID #1273. ALPO/BAA weight=1.
Herodotus 1950 Mar 30 UT 19:00? Observed by Wilkins (Kent,
UK, 15" reflector) "Transient c.p. (similar phen. to
Bartlett's in later yrs.? see #532). NASA catalog weight=4
(good). NASA catalog ID #523. ALPO/BAA weight=3.
Herodotus 1956 Nov 15 UT 01:05-01:30 Observed by Bartlett
(Baltimore, MD, USA, 3.5" reflector x100) "Pseudo c.p. clearly
seen est. I=5.5, wratten filters showed it neutral to green,
red, & yellow, but duller in blue. Floor est. 2deg, distinctly
olive-green. Precise time at 0117 at col. 55.27deg" NASA catalog
weight=4. NASA catalog ID #655. ALPO/BAA weight=3.
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.
