On 2010 Dec 09 at UT 17:00 A. Heath (Long Eaton, UK) whilst
observing the Earthsine with 10x50 binoucluars, noticed some
coloured bands on the night side. The NW sector of Eartshine,
closest the limb was a normal dull brown, there was a whitish
fringe on this going from the N to the SE, followed by a thicker
bluish fringe. The rest of the Earthshine beyond, until reaching
the illuminated crescent was black. The two coloured fringes
curved slightly. Local temperature 38F and some broken cloud
present. Thickening cloud prevented further observations. The
observer suspects that it could have been caused by the weather
conditions, but could also have been due to a cataract starting
to form in his observing eye. This is unlikely to be a TLP due
to the above observer suggested reasons, and anyway it would
have to have been an unbelievably large phenomena to cover such
a large part of the Moon. However it is worth checking to see if
anybody else was observing at the time. ALPO/BAA weight=0.
On 1985 Apr 23 at UT20:00 Smith (England, UK) found two large glows in
Earthshine, one was somewhere in the vicinity of Gruithuisen (i.e.
between Aristarchus and Sinus Iridum). The Cameron 2006 catalog ID=263
and weight=1. The ALPO/BAA weight=2.
On 1985 Apr 23 at UT20:00 Smith (England, UK) found two large glows in
Earthshine, one was west of Bullialdus crater. The Cameron 2006 catalog

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 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.

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.
Proclus 1983 Jan 19 UT 20:36-21:00 Observed by Cook (Frimley, UK,
Seeing III, Transparency, Moderate) "Colouration seen". BAA Lunar

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.
Mare Nectaris 1880 Jan 18 UT 20:00? Observed by Gaudibert (France?,
seeing poor) "Whole of sea was foggy. Fog extended into Fracastorius.
Gruithuissen said seeing was unsatisfactory" NASA catalog weight=0

1968 Apr 04 UT 18:45-19:20 Observed by Darnella (Copenhagen,
Denmark, 6" refractor, x183) "Small area just E(ast.) of
Menelaus was seen with a reddish color which gradually faded.

On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP
coordinator, Patrick Moore, to report a possible colour anomaly in
Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing
unusual. However by this time North was reporting that, the colour was
fading. Two other BAA members were alerted, but were clouded out. The
ALPO/BAA weight=3.
Webb (England, using a fluid achromat) saw brilliant minute spots and
streaks in Mare Crisium dotting its surface. This was seen near first
quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall
had all seen it this way at times. Cameron 1978 catalog iD=111 and
weight=3. ALPO/BAA weight=2.
Aristarchus appeared to glow in Earthshine with a faint
green luminescence that moved from side to side. A bright
blue central spot was also seen. The green colour was detected
in two seperate eyepieces. Observation made from England.

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.

Proclus 1972 Jan 23 UT 15:20-16:50 observed by Stolzen (51.17N, 9.25E,
50mm refractor, T=2, S=2) "Pure bright white point within crater" -
Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61
On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia)
noted that Mons Piton was too bright near the terminator and was
surrounded by shadow. A sketch was made. The mountain appeared
segmented with one thin shadow line. The mountain looked like a
Mexican Sombrero hat. This appearance is normal. What was
abnormal was that Piton was brighter than Proclus, and only
slightly fainter than Censorinus. The CED brightness
measurements were normal Piton=3.6, Proclus=3.5 and Censorinus=
3.7. Please check to see whether this is still the case. The
cameron 2006 catalog ID=221 and the weight=3. The ALPO/BAA
weight=1.
Cassini 1972 Jan 23 UT 16:55-17:15 P.Radford (Harlow, UK, 11.5cm
reflector) saw a large red flash followed by several weaker red
flashes, situated on the 32,335 foot spot elevation just above
the Cassini area. The ALPO/BAA weight=2.
"Eudoxus" 1877 Feb 20 UTC 21:30-22:30 Observed by Trouvelot
(Meudon, France, 13" refractor?) "Fine line of light like a
luminous cable, drawn W. to E. across crater". NASA catalog

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.
2004 Nov 20 UT 01:43:36 R. Spellman (120mm F8.3 refractor at
prime focus, PC23C CCTV camera, via a DVD recorder) recorded
a flash of light. 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.
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.
2004 Nov 20 UT 02:34:03 R. Spellman (120mm F8.3 refractor at prime

a flash of light. The ALPO/BAA weight=1.
A dome-like feature, sketched by Herring and confirmed in a photograph
by Larson. This had not been seen before by Herring in hundreds of
hours of observing. No other reports of this. The photograph was taken
at 02:50h. Cameron 1978 catalog ID=878 and weight=5. ALPO/BAA weight=3.
On 1982 Jun 30 at UT 02:05-02:15 Marco Petek (Porto Alegre,
Brazil) found that the region between Eratosthenes and Bode
(7W, 13N) looked like it had a darkening (cloud?) that had
even darker points inside. The Cameron 2006 catalog ID=172
and weight=3. The ALPO/BAA weight=2.
On 1984 Dec 01 at UT 20:00 a British Astronomical Association Lunar
Section member (Southam, Warwickshire, UK) found no detail on the floor
of Autolycus, despite there being plenty of detail on the floor of
Aristillus crater. According to Foley, there should be some detail at
this stage of illumination. Grego reports that the observation was from
a Society for Popular Astronomy member and they described "a
homogeneous grey veil over the 20 km floor of the crater". The
Cameron 2006 catalog ID=255 and the weight=2. ALPO/BAA weight=2.

On 1931 Mar 27 R.Barker (observing from Cheshunt, UK, 12.5" reflector)
found that the central mountain in the brilliant ray crater Tycho was a
curious shade of grey. This was despite the interior of Tycho being
fully in shadow. Cameron 1978 catalog ID=400 and weight=3. ALPO/BAA
weight=3.
Tycho 2003 May 10 UTC 03:15 Observer Robert Spellman (Los Angeles, USA)
- "CCD video of spur-like features coming off N & S edges of central
peak - spurs pointed eastwards". It is now thought that this effect is
almost certainly seeing flare as it is visible on other features in the
image, although to a much lesser extent. The ALPO/BAA weight=1.
Proclus 1972 Jul 19 UT 21:24-21:30 observed by S.Westmoorland
(Cropwell-Bishop, UK, 15cm reflector, x48 & x96, image dull
but steady) observed a brilliant spot in the NE (IAU?) wall
which lasted for about 90 seconds. After fading it was
replaced by pulsations for a further 2 minutes. Clouds
prevented further observations. ALPO/BAA weight=1.
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.
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.

Plato 1982 Jun 02 UT 22:00. Mobberley could not see the
central craterlet on the floor of Plato tonight. Foley notes
that he could only just see the central craterlet on nights of
2-5th Jun and it was of reduced in brightness from normal.
North reported that the floor seemed nearly black, but
brighter in a green filter (x144 magnification used). All
three observers compared the Plato area to other areas for

Deslandre - 1965 May 12 at UT 19:10 E. Penzel
(Rodewisch, East Germany) was taking a sequence of images
during the impact of the Soviet Lunik 5 (upper stage of the
carier rocket?). He detected a tens of km scale elongated
cloud after the impact over a duration of 9.5 minutes. This
was near to Deslandre crater. However there are differences
between the images elsewhere on the Moon, possibly due to
different exposures or some other effects and it is not 100%
sure that what he detected was impact debris/cloud?. The

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.
ALPO/BAA weight=4.
On 1965 May 12 at UT 22:20 H. Miles (UK) found a possible
obscuration in Bailly crater. Most of the region was as sharp as
normal, but the central area was greyish and blurred. Although
the observer concerned considered themselves a non-experienced
observer, another BAA Lunar Section observer saw the same
effect. ALPO/BAA weight=2.
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 1825 Jan 01 UT17:00? an unknown Russian observer noticed a

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.

about 1/7th the diameter of the crater. The eastern edge of the
white patch was encroached by the shadow of the eastern rim.
ALPO/BAA weight=3.
On 1995 October 6 at UT 21:30 R. Lena (Rome, Italy - a UAI observer,
11.4cm reflector) saw 4 or 5 flashes from Herodotus crater. Light
intensities (mag?) ranged from 9 to 8 and they were brighter through a
red filter. There is no 2006 Cameron catalog entry for this observation
- it has come from the UAI web site. The ALPO/BAA weight=3.
On 1995 Oct 06/07 at UT 22:45-00:00 P. Mirteto (a UAI

Aristarchus. 2024 Mar 22 UT 22:08. G.Vega (Argentina, Oro
Verde - 20cm f/5 Newtonian on an EQ5 Goto mount - two colour
cameras used: a Player One Ceres C & a Nikon D5100).
Colour images show a region of blueness from the W. rim of
Aristarchus and the NE of Herodotus (maybe also on the inner
SE rim of Herodotus?) i.e. generally SE of the Cobra's Head.
Blue colour is usually present on the rim of Aristarchus and
to the north - but I don't recall seeing such strong blue
colouration in this region before? No other craters exhibit
this blue colour. As the colour is present in two images,
taken with different cameras it looks genuine. Two other
colour images, at lower resolution, were taken from Oro Verde,
by W.Elias, at 23:06 and 23:18, but neither of these exhibit
this blue colour - but that maybe a resolution issue? ALPO/BAA
weight=3.0
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.

Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55
image very unsteady. All seems normal in other crtaters with
the exception of Arcimedes. Much of the rim seems indistinct
apart from a 1/4 length of the west rim. Strongly suspected
that this was due to a combination of seeing and illumination.
UT 20:02-20:06 - checked the area with a lower magnification
10" Astrographic Refractor - the crater seems more normal, so
suggesting that the theory was correct. 20:36-20:41 returned
to the 30" reflector, and the crater appeared similar to the
start of the session. This is almost certainly not a TLP, but
it would be helpful to have some images or sketches to check
this theory out. Weight=1.
On 1987 Mar 13 at UT02:00-03:00 De Groof (Belgium, 8" reflector x150,
seeing=clear) noted that the north west part of Aristarchus had a blood
red shimmering filling the whole crater. A video by Mobberley some 18
hours later, shows variation in Aristarchus. Cameron 2006 catalog ID=

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

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

Lictenberg Area 1940 Oct 19 UT 07:11 Observed by Barcroft
(Madera, CA, 6" reflector) Pronounced reddish-brown or orange
color. Less marked than previous night, & slight on 22nd. See
#'s 477; 478". NASA catalog weight=3. NASA catalog ID #476.

Aristarchus 1970 Feb 24 UTC 07:00? Observed by Thomas & Stump
(Corralitos Observatory, Organ PAss, NM, USA, 24" refletor+Moon Blink)
"Bluring around crater -- vis. in monitor, but not photographed due to
clouds." NASA catalog weight=4 (good). NASA catalog ID #1235.
Alphonsus 1972 Jul 29 UT 00:30-03:30 Observed by Morgan (England, UK)
"Orange spot just W. of c.p. on central ridge; circular area @ 15-25km
diam, larger than c.p. Was bright orange then turned orange-brown
toward center. Central 4,5km was darker than rest; bownish-black with
blue-white specks flashing in center. Obscur. there but ridge clear
elsewhere. The dark spot SW of c.p. could not be seentho outside of
color area. Sketch. It had appearance of dome of atm. thicker at
center. Never seen before in 11y. Next nite brighter. NASA catalog
weight=3. NASA catalog ID #1337. ALPO/BAA weight=1.
On 2002 May 30 at UT02:30-02:44 C. Brook (Plymouth, UK) suspected that
Aristarchus crater looked dimmer than normal. The ALPO/BAA weight=1.
On 1895 Sep 07 an unknown observer (Lewis Swift?) observed a pale blue
segment on the upper limb - this was apparently confirmed by Faulkes
(Mem. BAA, 1895). Cameron says that this is probably 1895 Sep 08 at UT
06:00 as Sep 07 is local time. She also infers that "upper limb" is the
southern limb and that Swift was at the Lowell Observatory, Flagstaff,
AZ, USA. The Cameron 1978 catalog ID=285 and weight=5. The ALPO/BAA
weight=2.
On 1983 May 31 at UT03:45-04:30 K. Marshall (Medellin, Columbia) noted
that the whole area of Aristarchus, Herodotus, and Schroter's valley
was both blurred and violet. There was hardly any detail seen inside
the crater. Herodotus could hardly be seen either and Schroter's valley
was totally unrecognizable. A sketch was supplied. The Cameron 2006
catalog ID=223 and the weight=3.
Alphonsus 1972 Jul 30 UT 00:30-03:30 Observed by Morgan (UK
using a reflector) "Orange glow, brighter this nite than last
nite. Following nites were cloudy. Aristarchus and Gassendi
were negative." NASA catalog weight=3. NASA catalog ID #1338.
ALPO/BAA weight=3.
On 1985 May 09 at UT 22:50-03:10 P. Foley (Kent, UK) observed
the whole of Aristarchus to be a strong violet color. No
colour was seen elsewhere on the Moon. The Cameron 2006
catalog ID is 272 and the weight is 2. The ALPO/BAA
weight is 2.
On 1985 May 09/10 at UT 22:50-03:10 P.W. Foley (Kent, UK) found that
Torricelli B was very bright in Earthshine and was blue in colour. The
Cameron 2006 catalog ID=272 and the weight=2. The ALPO/BAA weight=2.
Alphonsus 1959 Oct 23 UT 02:10-02:35 Observed by Kozyrev
(Crimea, Soviet Union, 50" reflector) "Red glows, emiss.
spect. got C2, C3 (Moore obs. 0100-0300 & saw nothing unusual
in an 8.5" reflector)" NASA catalog ID=723. NASA catalog
weight=5. ALPO/BAA weight=4.
Near Calippus 1973 Jan 25 UT 19:20-19:30 Observed by Frank
(E.Pepperell, Massachusetts, USA, 6" reflector, x100, S=G) "Bright spot
