In 1936 Jun 22 at UT 05:00 Roth, Weldy (Alliance, OH, Oak Park, IL,
USA, 10" refractor, 6" reflector) observed in the Southern part of mare
Crisium (60E, 10N) "Both noted reddish spots nr. S. end of mare, (Martz
could not confirm, moon had set for him)". The Cameron 1978 catalog ID=
415 and weight=4. The ALPO/BAA weight=3.
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
Section Report. ALPO/BAA weight=2.
Leibnitz Mountains 1948 Apr 14 UT 20:00? Observed by Wilkins
(Kent, England, 12.5" reflector) " S.cusp prolonged -- detached

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.
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.
Area was as large as Menelaus & had just come into sunlight. The

On 1984 Jun 05 at UT20:00 Marshall (Covington, UK) saw an unusual
darkening on the floor of Proclus and irregular shape. The Cameron 2006
catalog ID=243 and the weight=2. The ALPO/BAA weight=1.
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
weight=1. NASA catalog ID #185. ALPO/BAA weight=1.
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 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.
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.
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 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 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.

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.
A region of the Mare Imbrium was extremely bright, giving
a reading of 8 out of 10 on the Elger scale. Cameron notes
that from photos of the Full Moon, the area appears to
normally be the brightness of Archimedes floor i.e. 3.5 out
of 10 on the Elger scale. Atmospheric seeing was excellent
and the observer could see a lot of fine detail with their
2.4" and 3" refractors. Cameron 2006 catalog extension ID=62

Also Darney appeared very visible through the red filter. Probably
spurious colour as the Moon was -18 deg in declination and the whole
Moon had a slight brownish tinge" ALPO/BAA weight=1.
Darney observed by Cook (Frimley, UK, seeing III, Moonblink device)
See TLP report for Bullialdus (eastern side) concerning reddish
areas. At 21:41 it clouded over but at 21:47-21:48 it
cleared briefly and the effect was noted on Bulialdus again.
Also Darney appeared very visible through the red filter.
Probably both effects were spurious colour related as the Moon
was -18 deg in declination and the whole Moon had a slight
brownish tinge. An ALPO/BAA weight of 1 is assigned to this TLP."

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

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%

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.
Observed by Haas (Las Cruces, NM, USA) "Temporary greyness seen in
interior shadow." ALPO/BAA weight=3.
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 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.
Aristarchus Area 2004 Nov 22 UT 04:58-05:49 Observed by Gray
(Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5,
x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red
25. The illuminated west crater wall stood out brilliantly in blue
light, much more so than in white light. This was true also of
Aristarchus. Red light did not increase contrasts in Herodotus any more
than they were in white light. Shadows in Herodotus appeared as black
as the night west of the terminator and remained that way throughout
the observing period. No TLP seen in Herodotus tonight. A possible TLP
was seen to the west of Herodotus near the terminus of Schroters
Valley. It was noted at the beginning of the observing period that
there were four very bright spots of light, one near the end of
Schroters Valley, the other three grouped together a little farther
north. Although not far from the terminator they were definitely east
of it. It was noted that all of them nearly vanished in the Blue 38A
filter while Aristarchus and the rim of Herodotus gleamed brilliantly.
At 5:19UT it was noted that the most brilliant of the four lights, the
one near the terminus of Schroters Valley, had faded almost to
invisibility in white light. When first seen it had been brighter than
Aristarchus. It remained very dim after this through the remainder of
the observing period, and was unchanged at 7:35-7:49UT when I again
examined the area. The other three bright spots remained brilliant and
unchanged."
Herodotus 1956 Nov 15 UT 01:05-01:30 Observed by Bartlett

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

Coude Rrefractor, x250, Royal Grenwwich Observatory,
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 1995 Oct 06/07 at UT 22:45-00:00 P. Mirteto (a UAI

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.

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

Promotorium Laplace: 1978 Apr 20 UT19:30-22:35 Peter Foley
observed a tiny yellow-brown region close the tip of the cape,
north east of the precipitous west edge, in the face of the
north facing slope. The area concerned was diffuse and varied
in density despite the surroundings not varying. Foley notcied
no colour elsewhere on the Moon, though Amery thought that he
saw some in Aristarchus, but Foley thinks this was spurious.

On 1964 Dec 19 at UT 03:13-03:14 Budine and Farrell (Binghamton, New
York, USA, 4" refractor, x200, S=7, T=5) observed that Aristarchus
brightened five times over 1 minute during a lunar eclipse. The cameron
1978 catalog ID=870 and weight=5. The ALPO/BAA weight=3.
On 1956 Nov 18 at UT 00:00? an unknown observer (Cameron gives an AGU

Cameron 1978 catalog ID=657 and weight=0. The ALPO/BAA weight=1.
Kepler 1962 Jul 17 UTC 06:24,08:36 Observed by Wildey, Pohn (Mt Wilson,
CA, USA, 60" reflector+photometer) "Crater was at Vmag 2.68 at earlier
obs. which was .47 mag brighter than av. mag. at 15d & it faded to near

On 1960 Sep 04 at UT00:00? Miranova (Russia or Israel) observed a TLP
at an unnamed lunar feature: "Spectral photom. of some lunar obj. in
4250, > 5000A bands. Spectral plates". Cameron suspects luminescence?

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
1978 catalog ID=297 and the weight=0. The ALPO/BAA weight=1.
On 1983 Jan 29 at UT22:09 M.Mobberley (Sulfolk, UK, 14" reflector)
noted that Arago B had a slight tinge of violet colour, and was a lot
less (bright?) than Torricelli B's blueness. Other craters checked but
were not showing any blue colour. The Cameron 2006 catalog ID=198 and
weight=5. The ALPO/BAA weight=3.
On 1983 Jan 29/30 at UT20:35-01:00 Sykes (UK?) observed that
Linne appeared to brighten for approximately 20 min and had the
appearance of a point (confirmed). This observation was made
during a major Torricelli B TLP. The Cameron 2006 catalog ID=198
and the weight=5. The ALPO/BAA weight=2.
On 1983 Jan 29 at UT22:09 M. Mobberley (Suffolk, UK), found that Moltke
crater was "exceptionally bright". Other craters (apart from Arago B
Torricelli B etc) appeared normal. The Cameron 2006 catalog ID=198 and
the weight=5. The ALPO/BAA weight=2.
Torricelli B 1983 Jan 29/30 UTC 20:35-02:30 Observed by Foley (12"
reflector, seeing Antoniadi II, Transparency=good, no spurious colour
seen), Moberley (14" reflector, seeing Antoniadi II, transparency
excellent, spurious colour strong), Cook, J & M (12" reflector, seeing
Antoniadi II-III, transparency moderate). All observers based in
southern England. "Initially crater brightest feature on the Moon, then
it faded. Strong colour also seen by all observers e.g. green-blue to
violet. Report of observations written up in JBAA Vol 100, No. 3, p117
123, (2000) - probably one of the best reorted TLP". The Cameron 2006
catalog ID=198 and weight=5. The ALPO/BAA weight=5.
On 1983 May 28 at UT 01:50-03:00 K. Marshall (Medellin, Columbia)
observed the whole region of Aristarchus, Herodotus and Shroter's
Valley all to have a brightness of 3 and all blue and impossible to
focus on (he had never seen it like this before). Also the interior of
Aristarchus was invisible. Brightness measurement taken and a sketch
was made. The Cameron 2006 catalog ID=222 and the weight=3. The
ALPO/BAA weight=2.
On 1985 May 05 at UT23:25-23:58 UT P. Moore (Selsey, UK) observed a
yellow tinge on the southern wall of Aristarchus - this was odd because
no colour was seen elsewhere on the Moon. The Cameron 2006 catalog ID=
271 and weight=3. The ALPO/BAA weight=3.
On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50)
observed a bright flash (~0.3 sec duration) near to Copernicus (20W,
9N) with rays to the south east whilst he looked through a finder
scope. Moore, who studied the drawing, suggests that the area of the
flash was near Copernicus. However Cameron says this cannot be the case
if the flash was in darkness as mentioned in the BAA Lunar Section
circular. She comments that it might have been a meteor? The Cameron
2005 catalog ID=28 and weight=1. The ALPO/BAA weight=1.
On 1956 Nov 19 at UT 00:00? an unknown observer (Cameron gives an AGU
meeting reference) apparently saw a TLP in Aristarchus crater. The
Cameron 1978 catalog ID=657 and weight=0. The ALPO/BAA weight=1.
Littrow 1915 Jan 31 UTC 22:00? Observer: unknown (England?) "6 to 7
spots arranged like a gamma first seen on this nite. (Kuiper atlas.
Rect. 14-c shows spots in form of a 7 or a cap. gamma backwards, but
not l.c. gamma)". NASA catalog weight=0 (almost certainly not a TLP).
NASA catalog ID #349. ALPO/BAA weight=1.
Aristarchus 1970 Feb 22 UTC 07:00? Observed by Thomas, Stump, Corral.
Obs. (Organ Pass, NM, 24" reflector+Moonblink) "Bluing around crater --
vis. in monitor, but not photographable due to clouds." NASA catalog
weight=4 (good). NASA catalog ID #1235.
Proclus 1955 Nov 01 UTC 02:50-03:05 Observed by Bartlett (Baltimore,
MD, USA, 3.5" reflector x100, S=6, T=5) "Proc. D normally 5 deg bright
was vis. tonite only in blue light, whereas usually is vis. in
integrated light. However at col. 110.5 deg it was a dark spot (see #
816) C.p. tonite was normal 5 deg bright but in Oct. lun. was dark".
NASA catalog weight=4 (good). NASA catalog ID #625. Note Proclus D does
not refer to the crater Proclus D as defined by the IAU, but probably
to a spot inside the crater that Bartlett designated D!
On 1983 Jan 30 at UT 23:45 Chapman (England, UK) observed that
Censorinus was low in brightness. The Cameron 2006 catalog ID=199 and
the weight=4. The ALPO/BAA weight=2.
On 1983 Jan 30 at UT 23:45 P.W. Foley (Kent, UK, 12" reflector)
measured that the brightness of the region around Toricelli B was 2.3
(high) and there was a slight blue colour. The Cameron 2006 catalog ID=
199 and the weight=4. The ALPO/BAA weight=2.
Herodotus 1972 Jul 27 UT 2250-2350 M.Brown (Hutington, UK)
thought that he saw a pseudo peak in the centre of Herodotus.
He could not decide if it was real or an optical illusion.
ALPO/BAA weight=1.
Aristarchus 1970 Feb 23 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.
On 1990 Aug 08 at OT 07:47-09:00 UT D. Louderback (South Bend, WA, USA,
3" refractor, x173) "(SS) Piton's all pts were << but nearby plain was
normal. Ridges at 5.3 at B, C, D but 3 alb at B, C, D (norm = 7) but
bearby plain was normal. At A 3, was hazy but ill defined. Parts of mt
brightened but others didn't. Times between brightening were 6-8s.
Similar to seeing fluctuations. In red mt stayed dull & steady. In blue
it blinked." - this is a direct quote from the Cameron 2006 catalog
because it is very difficult to summarize. Louderback comments that the
TLP was still going on at 09:00UT. The Cameron 2006 catalog ID=406 and
the weight=4. The ALPO/BAA weight=3.
On 1990 Aug 08 at UT 07:47-09:00 D. Darling (Sun Praire, WI, USA, 3"
refractor, x173) reported the following TLP in Promontorium Agarum
(Cape Agarum): "W flank of CA >>, even> Proc. interior." The cameron

Mare Crisium 1962 Jul 19 UTC 07:30 Observed by Wildey & Pohn (Mt
Wilson, CA, USA, 60" reflector + Photometer) "Photometric meas. showed
change in brightness from Vmag=3.46 to V=3.07, where av. mag. for that
age=3.26, or a brightening of .58 mag." NASA catalog weight=5 (very
high). NASA catalog ID #763.
Plato 1938 Jun 15 UTC 08:00 Observed by Haas? (New Mexico?, 12?"

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.
Aristarchus 1970 Feb 24 UTC 07:00? Observed by Thomas & Stump
(Corralitos Observatory, Organ PAss, NM, USA, 24" refletor+Moon Blink)

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.
Observed by Bartlett (Baltimire, MD, USA, 5" reflector, x150) "N. half
of crater hazy & ill-defined". S=5, T=4. NASA catalog weight=4 (good).
NASA catalog ID 571.
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.

On 1979 Aug 12 at UT07:00-10:35 D. Darling and wife (Sun Prarie, WI,
USA, 12.5" reflector, x342, photos, S=9/10) observed a cigar shaped
protruberance in Romer crater that cast a 32km long shadow, nestled in
a valley rille next to Romer. This was a confirmed observation. The
effect persisted intil sunset. The top of the object and two points on
the crater rim were reflecting the Sun's rays. "Top of obj. & 2 pts on
crater rim reflected suns rays. It was as high as the crater rim
whereas the rill wall was not. Took photos. he has studied this area
and never saw such a phenom before. Photos did not show it". The
Cameron 1978 catalog ID=65 and weight=5. The ALPO/BAA weight=2.
Observations made with a variable polarizer (akin to a crater
extinction device) to measure brighness with red and blue filters.
Some variability in brightness noted. With the Kodak Wratten
25 and 38A filters there was little or no increase in contrast with the
red filter, but with the blue filter there was a great increase in
contrast of the brighter areas of the crater - the crater floor and
patches of lighter material, especially at the north end. The remaining
areas were supressed with the Blue 38A. ALPO/BAA weight=3.
Alphonsus 1956 Oct 26 UT 12:54 Observed by Alter (Mt Wilson, CA,
USA, 60" reflector, S=E) "Photog. thru UV & IR filters. Obscur.
of E. 1/2 of floor evident in blue plates -- KodakII-O plate no
filter. 2m later Kodak I-N. One pair of plates best he'd ever
seen. Similar obscuration seen 2X on Linne (this started Kozyrev
on his spectrographic program.)." NASA catalog weight=5 (very
high). NASA catalog ID #653.
On 1980 Jul 05 at 03:20UT P.Moore (Selsey, UK, 12?" reflector)
found Aristarchus to be "Very brilliant indeed". Cameron 2006
TLP catalog ID=100 and weight=3. ALPO/BAA weight=2.
On 1969 Feb 12 at UT 12:00 Taboada (Mexico, seeing=excellent) found
that the Aristarchus region had the same characteristics as the
previous days, perhaps a little darker colour brown, but more
remarkable. He used red, blue and green filters and a difference in
colour was noticed in and out of the region. Cameron suspects that
permanent colour was being seen? The cameron 1978 catalog ID=1116 and
weight=3. The ALPO/BAA weigh=2.
On 1983 Feb 08 at 06:30UT Toricelli B was observed by P.W. Foley (Kent,
UK, 12" reflector) to be visible in Earthshine as a luminous patch.
This was rather odd because it is only a small crater and not normally
bright. The Cameron 2006 catalog extension ID=201 and the weight=2. The
ALPO/BAA weight=2.
