Observations made by Challis of Cambridge, and N. Pogson of Hartwell,
both of the UK. Before the occultation, Saturn's rings were
distorted. A dark border was seen around the Moon. Just before
re-appearance a sea green colour was noticed. Cameron 2006

On 1975 Mar 18 at UT17:30 M.Kidger (Winterbourne Down, Bristol, UK,
60mm refractor, x36, very good conditions with a very sharp image and
the sky was almost perfectly clear apart from a very few small clouds).
In Mare Crisium it was observed that only a ray of Proclus could be
seen to cross the floor - normally there are at least four craters
visible inside mare Crisium on good nights and at least one being
visible under bad conditions. So despite it being very clear and the
image quality being good, the observer found it odd that no craters
were visible on the floor of mare Crisium. This is a BAA Lunar Section
report. The ALPO/BAA weight=2.
In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of
twilight (Cameron says also seen by Gruithuisen, Henry and others at
times). Webb gives a low weight to his own observation, saying "for
want of better optical means". The Cameron 1978 catalog ID=130 and
weight=1. The ALPO/BAA weight=1.
On 2012 Mar 28 at UT 20:45-20:50 Two unknown Italian
observers, reported on an on-line formum that they had
independently seen a distinct glow with a comma/drop shape.
One of them moved the Moon and the glow moved with the Moon.
It is uncertain how experienced the observers where. A chart
was provided which shows the lcoation of the glow in the
western side of Mare Imbrium. It is just possible that this
was Aristarchus in Earthshine, though that is very slightly
further west and south than the observers reported. ALPO/BAA
weight=1.
On 1969 Jul 20 at UT09:30 Whelan (Wellington, New Zealand, 10"
and 6" reflectors. Other observers involved were: Mackrell
(New Zealand, 6" reflector) and Spellman (4" reflector)
observed Maskelyne crater undergoing a whitish glowing
brightening. Shadowy filling of whole crater. Apollo 11 watch.
The Cameron 1978 catalog ID=1179 and the weight=3. The
ALPO/BAA weight=2.
Posidonius 1969 May 23 UT 11:35-12:45 Observed by Osawa (Hyogo-ken,
Japan, 8" reflector x286) "W.(ast. ?) rim of crater was yellow in
integ. light, brownish to deep yellow in filter, with no blink.

catalog ID #1141.
On 1970 Apr 13 at UT09:00-09:03 Whelan (Walters, New Zealand, using a
10" reflector) observed Menelaus to have a deep red cloud that seemed
to surge upward from outside the southern edge of the crater wall and
disperse around the outside edge, spreading out on reaching Mare
Serentiatis. All clear again though by 09:03UT, (Apollo 13 watch).

Hernandez (Aguadilla, PR, 8"SCT, x225, S=7, T=4) "Interesting
configuration of shadows with umbra and penumbra. Effect seemed to
reduce over time." An ALPO report. The ALPO/BAA report=2.
2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw
Mons Pico to be incredibly bright. Adee reported naked eye visibility,
though this does not show up in later CCD images. Jarwaski saw another
nearby Mt very bright as well. This has been assigned an ALPO/BAA
weight of 1, though I suspect it is just normal for Pico to get quite
bright at sunrise.
Patches of brightness seen in the area between craters Aratus and Joy.
Seemed to the observer to be perhaps slightly brighter than one would
expect - the observer thought that their observation only barely
constitured a TLP but decided to send the report in anyway. This
has been assigned an ALPO/BAA weight of 1.
On 1983 Sep 15 at UT 05:20-05:24 Louderback (South Bend, WA, USA,
8" reflector and 3" refractor, seeing poor) found that the west wall of
Eimmart was unusually bright (8.3) and apparently it was almost as
bright as the "WEBS(of Aris?) at its brightest". The crater was
apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID=
228 and the weight=3. The ALPO/BAA weight=2.
Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson,
Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw
something in Proclus, alerted Jamieson who saw nothing unusual
at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw
Proc. fluctuate. Red & blue filters showed some reduction in
brightness. E. edge showed darkening, but not as dark as in
shadows. 10 min later, returned to normal. (Sparks confirmed
Dean)." NASA catalog weight=5. NASA catalog ID #1267. ALPO/BAA

weight=1.
On 1990 May 03 at UT 02:03 D. Darling (Sun Praire, WI, USA, seeing
steady) observed a point of light inside Alphonsus just to the north
of the central peak, along the "center ridge". It was seen again, half
way between the central peak and the noth west rim - along the ridge.
All other features were normal. The Cameron 2006 catalog ID=403 and the
weight=3. The ALPO/BAA weight=3.
Purbach 1970 Apr 14 UT 12:00-14:00 Observed by Osawa (Awajt-Shima,
Japan, 8" reflector, x288) "Photos in blue and orange taken. Ill-
defined obscur. in blue photo in S. part of crater compared with
orange. (neg. is so faint it is doubtful. Apollo 13 watch. Similar to
Alter's findings in Alphonsus)." NASA catalog weight=2 (low). NASA
catalog ID #1250.
On 1972 Apr 21 at UT19:01 Mattingly (Apollo 16 commander, in orbit
around the Moon, using his naked eyes) saw a bright flash from below
his horizon on the lunar farside (approximate longitude=180 deg). he
was dark adapted at the time. However no sesimic event was recorded and
so Cameron suspects that this was not a meteor impact but a cosmic ray
striking his eye. The Cameron 1978 catalog ID=1331 and weight=3. The
ALPO/BAA weight=3.
Alphonsus 1967 Aug 13 UT 18:40-18:55 Observed by Horowitz (Haifa,

On 1988 Jul 23 at UT03:07 D. Darling (Sun Praire, WI, USA, 12"
reflector, x150, seeing = 6/10) discovered that the dark area on the
floor of Proclus, seen earlier by UK observers was still present, but
less so (?) and the shape changed. When viewed through a green filter
it was less distinct. "Change with two other filters. Polarizer gave a
circular shape with a knot on SE side & W58 in White." The measured
brightness of Proclus was 9 on three sides and 8.5 on its west rim. The
floor was 5.5, but the dark spot was 4. Alphonsus, Bullialdus,
Copernicus, Eratosthenes, Plato and Ptolemeaus were all normal. The
Cameron 2006 catalog ID=332 and the weight=1. The ALPO/BAA weight=1.

x200, seeing = excellent and transparency = excellent) observed "A fine
deep red line seen at 1st contact with B-ring of Saturn. Nothing
unusual at A-ring contact. Persisted during occult. of B-ring. It
divided into 2 components & space between B-ring & globe cutting ring

Saturn, then a short red line corresponding exactly to chord of planet
disk defined by lunar limb. It increased in length as occult.
progressed. It suddenly vanished after 3/4 of globe had been occulted.
No afterglow at spot on limb, no irreg. at limb could be seen. Obs.
eliminates Saturn, telescope, & atmosp. as possible cause. Suggests
refraction from tenuous atm. of destructive interference of reflected
light from very small angle at limb, or diffraction of Saturn light
grazing limb". The Cameron 1978 catalog ID=1389 and weight=1. The
ALPO/BAA weight=1.
Linne 1867 Jan 14 UT 20:00 Observed by Knott (England?) "White covering

On 1974 Mar 3 at UT 19:06-20:20 J-H Robinson (Teighmouth, Devon,
UK, 10" refractor, x200, seeing=poor) got a Moon Blink reaction
on the South east wall of Plato, adjacent to the rim shadow and
alerted the BAA TLP network. Ford reported a negtive result at
19:35UT, although Robinson was still getting a blink reaction at
19:40UT, albeit fainter, red at times. Findlay at 19:43-19:52
and 20:00-20:05 saw nothing unusual. Robinson at 19:56UT no
longer saw a blink, but it returned at 20:05UT. Light in bothred
and blue filters. Not steady, but coming and going and gone at
20:09UT. Moore at 19:59-21:00, kennedy at 20:12-20:30, Taylor at

III-IV and trasnaparency good) observed a light orange transparent
cloud extending from the north east inner corner across over the floor
of Plato. Camero comments that this report was confirmed by 3 othr
observers. The shape of this clud varied. The Cameron 2006 catalog ID=
153 and weight=4. The ALPO/BAA weight=3.
On 1988 Jul 24 D. Darling (Sun Praire, WI, USA, 12" reflector,
x150, S=7/10, T=3) observed the following in Proclus: "At 0213
the previously observed gray area was 1/3 of July 22 and V
shaped and fanned out across the floor. Could see hint of knot
seen before. Craters named in 7/23/88 (#319) were all normal
this time too". Is it possible that this report refers to the
crater "Gray" rather than "Proclus" as the column field suggests
in the Cameron catalog? The Cameron 1978 catalog ID=333 and
weight=5. The ALPO/BAA catalog weight=2.
On 1975Mar22 at UT 21:17-21:23 Findlay and Ford (Mills Observatory,
Dundee, UK, 25cm refractor, Wratten 25 and 44a filters used) A white
spot was observed on the rim of Bulialdus that was perhaps slightly

3" refractor, x150, seeing poor and chromatic aberation on the limb)
detected "purple"in the vicinity of Aristarchus crater and this was
stongest on the north and north west external rims, however there was
no "violet glare"from inside the crater. However the region of the
central peak was very bright - though he could not detect the central
peak. The brightness of the TLP was 4.5 and it should normally be 3

seen on the crater. There was also violet on the northen wall of
Herodotus crater and the Cobra Head. Īt appeared dark blue in the blue
filter", the surrounds remained gray". Apparently on the 26th the"ring

On 1982 Oct 08 at UT 04:15-04:30 W. Cameron (Silverspring, MD, USA,
3.5" reflector, x160) found that Clavius had a "D" shaped crater on its
outskirts that made it appear to have a ridge crossing through it.

Tycho 1983Aug30 UT 00:15-00:18 R. Moseley (Coventry, UK, 6"
f/10 reflector, x60, transparency very good, seeing III,
improving with altitude) attention initially caught by the
impression of a rosy colouration along the NW crest and outer
wall. For perhaps 2-3 min this persisted - before fading
entirely. The observer felt that the cause may have been
psysiological - or short-lived spurious colour. However
interestingly nearby craters did not show the effect. A
sketch was made over a longer time span 00:15-00:40UT.

Linne 1918 Apr 04 UTC 01:00? Observed by Markov (Russia) "In place of
crater only a hill 2km in diam. was vis. (seen in dark). " NASA catalog
weight=1, low, NASA catalof ID #368. ALPO/BAA weight=1.
Aristarchus appeared dimmer than normal.
This report has an ALPO/BAA weight of 1.
On 1978 Jan 02 at UT23:00? A.V. Arkihpov and A.R. Kharkov (USSR)
observed in the terminator region (near Adams?) a flash enclosed by a
fuzzy envelope (180x120 arc seconds in size). The TLP faded away over
30 seconds. Cameron says that this is the first example of many
photographs that registered activity. The Cameron 2006 catalog ID= and

On 1989 Jun 28 at UT 08:39-09:00 D. Darling (Sun Praire, WI, USA,
3" refractor, x36) discovered that at this time Mons La Hire was the
brightest feature on the Moon. LaPrice was also very bright. Cameron
quotes that Darling recorded that LaHire had a brightness of 7.0 and
LaPlace=7.5. Darling did not think that this was a TLP. The Cameron
2006 catalog ID=369 and weight=0. The ALPO/BAA weight=1.
On 1989 Jun 28 at UT 08:39--9:00 D. Darling (Sunpraire, WI, USA, 3"
refractor, x36) noted that promontorium LaPlace was very bright.
LaHire brigtness was 7.0 and LaPlace was 7.5. Darling suspects
that this was not a TLP because "as did not have mother-of-perl
appearance as seen on Piton at times"The Cameron 1978 catalog ID=369

On 1982 Nov 11 at UT 17:00-17:30 E.V. Arsyukhin (Moscow, Russia, 3"
reflector) saw three stationary dark spots suddenly appear in Mare
Crisium. There was one on the north and the other two in the south west
to south. They lasted approximately 30 minutes and then promptly
vanished. Cameron says that it cannot be this date because the Moon was
not visible at 17:00UT Suggests 05:00-05:30UT? The Cameron 2006 catalog
ID ID=189 and weight=3. The ALPO/BAA weight=2.
On 1978 Jan 06 at UT 01:00 Anorati (Firenze, Italy) observed inside a
"good sized crater?" an orange light that became bright green. The
efect did not recur over the many hours of observing. The observer did
not suspect that it was a meteor, but instead produced by an
intelligent being????? Cameron suggests a terrestrial meteor?
The Cameron 1978 catalog ID=21 and weight=1. The ALPO/BAA weight=1.
On 1990 Feb 16 at UT18:00 Schroter(Lillienthal, Germany) saw a small

spot in Earthsine, just north of Aristarchus (47W, 25N) at position
angle 30deg-40deg, only a little way in from the limb. It appeared like
a star through haze and a few seconds of arc in diameter. It was
