Linne 1868 Jul 28 UT 20:00? Observed by Tacchini (Palermo, Italy)
"Shadow not so marked-had a light penumbra, indicated a feeble cavity.
Other craters had a black shad. On 29th appeared completely white.
Crater normal on 26th. (letter to Madler Sep. 16, 1868)." NASA
catalog weight=4 (high). NASA catalog ID #159.
On 1989 Feb 15 at UT 03:15-03:30 M. Dixon (Palenque Ruins, Mexico, 7x35
binouculars) observed a point of light that was very bright in or near
Mare Humorum. It was visible for 5 minutes then vanished. The Cameron
2006 catalog ID=353 and weight=1. The ALPO/BAA weight=1.
Copernicus 1955 Jul 28 UT 20:20 Observed by Firsoff (Somerset, England,
6.5" reflector x200) "Great brilliance of the terraces in E(IAU?) wall
system(?) gets specular refl. (he gave 0820UT, but must have meant
2020" NASA catalog weight=4 (high). NASA catalog No. #600.
Aristarchus 1976 Jun 06 UT 21:30-21:40 S.Spencer and R. Hunt
(60mm refractor, x150 and x60) both observed red on the SW
corner of Aristarchus. ALPO/BAA weight=1.
On 1952 Feb 05 at UT 05:10 J.Carle (USA, 8" reflector, x180)
observed the following in Plato: "A shadow in a depression, or
a cloud, or an optical illus.? Oval dark area nr. center,
disappeared in 15m clear & prominenet at first then vanished.
4 of 14 spots nr. center continuously seen while remaining
ones seen only momentarily. (seeing?) Drawing includes sketch

On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3"
refractor, x90, seeing conditions: "at,. boiling") noted a coloured
area on the west wall of Copernicus that was unusual in appearance -
however other craters along the terminator had a similar effect. There
was also a "dazzling bright spot on the E. rim and he witnessed 6
flashes from the lighted part of Copernicus over a very short time
interval. Cameron comments that the colour may well have been dur to
chromatic aberation because a refractor was used. The Cameron 2006
catalog ID=408 and the weight=0. The ALPO/BAA weight=1.
On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3"
reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc.
bright interior uniform gray". The Cameron 2006 catalog report is
slight unclear as the description for thnis 1990 Aug 30 TLP also
includes Copernicus and Censorinus in the list of TLP craters. So one
description which might refere to Copernicus, could possibly have been
meant for Proclus, namely: "Dazling bright spot on E rim. Rotated
eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog
ID=408 and weight=0. The ALPO/BAA weight=1.
Alphonsus 1966 Nov 22 UT 03:17-03:40 Observed by kelsey (Riverside, CA,
USA, 8" relector x300) "Seen first with (Eng.) moon blink, red filter
but not in the green. Not seen at 03:42h" NASA catalog weight=4 (high).

Arsyukhin and others (Moscow, USSR), with naked eye and binouculars
saw TLP activity in Plato that Cameron thinks confirms what UK
observers saw later. Cameron 2006 catalog extension ID=145
and catalog weight=4. ALPO/BAA weight=1.
On 1882 May 27 ay UT 20:00 an unknown observer (10" reflector) saw a
bright luminous ray near west (astronomical?) wall on floor of Plato.
Cameron suggests sunlight between peaks?. The Cameron 1978 catalog ID=
233 and weight=0. The ALPO/BAA weight=1.
Ross D 1966 Nov 23 UT 04:50-05:02 Observed by Cross (Whittier,
CA, USA, 19" reflector, x250 & 2390, S=4-5 (sometimes 6), T=4,
excellent contrast) Activity level 5, eastern third of Ross D's
circumference possibly partly obscured. ALPO/BAA weight=1.
On 1987 Oct 03 at UT 01:0?0-02:00 R. Manske (Brooklyn, WI, USA, 8"
reflector, x226) observed sunlight glinting of the walls in spectacular
display of colours. White (even gold) was seen at the centre, and blue
on the top most part of the rim. The white (or gold) band was thin in
comparison to other bands. The observer suspects that this effect was
terrestrial atmosphere related. Cameron 2006 catalog ID=307 and weight=
0. ALPO/BAA weight=1.
P. Moore at 21:10 found the southern wall (and ontothe southern floor)
of the crater to be indistinct. Elsewhere in the crater everything was
sharp. The effect was still seen at 21:42UT, but less strong. A check
was made for colour with aq Moonblink device, but none was seen. There
was still a trace of this effect at 21:44UT, although detail was now
becoming visible. By 21:48UT vertical streaks were seen crossing
the floor from the obscuration area and these were more visible in the
red filter and not in the blue. Cameron comments that undefined patches
on the floor of Plato are not normal. By 21:55UT some craterlets on the
floor started to become visible and the TLP for Moore ended by UT22:23.
P.Foley was alerted by Moore and saw a "amssive dense obsecuration
on the south wall, south floor and south outer glacis to the Mare".
Foley noted that by 21:50UT the effect was fading and finished by
22:03UT. Foley reported an orange translucent haze covering half of the
floor, but floor craterlets could be seen on and off - however his
atmospheric seeing conditions were IV. At 22:00 UT Foley reported the
floor close to the north wall to be "milky or misty". No detail was
visible at 21:15UT and variability in the floor continued until
23:10UT. Hedly-Robinson was aleted at 21:35UT and found no difference
between red and blue views of the area, however he did find that the
south rim was indistinct although this effect had lessened by 22:00 UT
and was normal by 22:17UT. M. Mobberly saw a white spot on the floor at
21:20 UT, whereas he normally would have expected to see craterlets.
Mobberly was alerted at 21:40 UT and took some colour photos. He also
made sketches that showed variability in the floor and dark lines and
patches in the north west corner. However the altitude of the Moon was
low. Cameron mentions that two of the photos show loss of detail at the
south wall and beyond.and also a change in the floor markings.The north
wall at 21:50UT was strangely reddish (didn't think this was spurious
colour). The rest of the wall was sharp at 22:20UT through a yellow
filter. Large bright patch in the centre and rest of the floor was
apparently of the same shading as Mare Imbrium. The above notes are
based upon the Cameron 2006 catalog extension TLP ID 145 and weight=4.

On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5"
reflector, x159) observed an "anomalous black bar across Aris. Nearly
digonal to terminator." The nearby crater Prinz had curious shadow
patterns, perhaps related to the rising sun projecting shadows from the
eastern rim and "reflected down"? "At 0224 W wall had a break in it & a
diffuse glow where it should not be. Manske thinks it was Earthshine
effect. At 0305 Weier saw Manske's bar - with diffused light and
flicker like an aurora - like a gas with electric charge. At 0325 saw a
strange glow in Aris. but may be due to atm. though thought it to be a
LTP. Darling had never seen such effects before (flickering implies a
medium in it)." The Cameron 2006 catalog ID=387 and the weight=3. The
ALPO/BAA weight=3.
On 1977 Apr 29 at UT21:40-23:20 an unknown UK observer reported a TLP
in Gassendi crater. The following are reports by observers attempting
to confirm activity: J.W. Napper (Didcot, UK, 30cm reflector, x287,
Wratten 25 and 44a, conditions clear 5+) received a telephone alert
call at 22:00 but the sky was cloudy until 22:30. An initial look
revealed nothing unusual, then at 22:54 he observed a colour blink just
inside the north wall, appearing bright in red and normal in blue or
white light. No loss of detail seen and the effect lasted only 2
minutes. A sketch was made. However the observer stresses that the very
bad seeing casts some doubt on this observation. L. Fitton observed
using a 8.5" reflector, with Moon blink device at x200, seeing was I-
II. All areas negative, including Gassindi from 21:40-21:55 and again
22;00-22:25 and finally 22:50-23:30 negative. Mike Brown (Huntington,
York, UK, 30cm reflector, x220 and x350, seeing 3-4/5, and transparency
5/5) - observed from 22:00-23:25UT no colour seen, nor obsecuration,
all filters negative, despite seeing a lot of fine setail inside this
crater.
On 1980 Jul 23 at UT22:00 G.W. Amery (Reading, UK, 8" reflector, x144
and x207, seeing=III-V and transparency=fair) found that the interior
shadow was a light grey. BAA TLP coordinator (Foley) suggests that this
was light reflecting from the illuminated walls? Cameron 2006 catalog

Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon,
England) - observer noted that the east outside wall was bright in red
and normal in blue. Note that the Moon was 30 deg above the horizon at
the time of the observation. The crater returned to normal at 20:58.
Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D.
Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at
times) noticed a possible obscuration over the southern part of
Gassendi. He had been observing earlier at 18:40-19:30 but had not
detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot
outside the east wall is again bright in red., though by 22:25 it had
faded and was gone by 22:28UT. The Cameron 1978 catalog further
quotes: "Vivid red spots & general red color seen around rim by 2 obs.

Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore
(Sussex, UK) saw the wall as normal. However Cameron points out that
Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely
(Covington, UK) at 22:10 UT noticed a brightening on the East wall and
at 01:10-01:25 UT suspected that the interior had a weak yellow-green
cast to it. Cook (Frimley, UK) states that orange colour was within the
interior crater, but green beyond the east rim at the 9 O'Clock and
the south east corner to floor blue/mauvre beyond the northern rim
NW/WSW. Foley sstates that orange and blue/mauvre might be spurious
colour, but green one cannot get this way. Cameon suggests chromatic
aberatons as a possibility but thinks that the observers concerned were
experienced enough to recognize this if it were the cause. Cameron 2006
catalog extension ID=239 and weight=0. Moore used a 15?" refletor and
Foley used a 12" refletor. Mosely experienced II seeing and good

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.
Manillus 1955 Aug 03 UTC 21:00 Observed by Firsoff (Sommerset, England,

On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a
6" reflector, Seing = 6/10) noticed blue on the north east corner of
Aristarchus and an orange glow on the south east wall. They detected no
movement or change in brightness. The observer used both eyes, to make
sure it was not an eye defect, and three filters: red Wratten 25, blue
Wratten 82 and Violet Wratten 47. Porter found that the colours faded
for a duration of 5 minutes and then returned. Their right eye gave a
good view and using their left eye they suspected that it was 0.5 steps
brighter than the remainder of the crater. The suspected colour
remained visible, even under moments of good seeing conditions. The
colour eventually faded over time and was eventually gone. Porter
reportd seein gcolour here on the following night. Apparently other
bright spots showed no colour. Fitton suggests that the filters used
confirm that the south east wass was definitely red in colour. The

On 1990 Dec 03 at UT23:00-01:30 M.C. Cook (Frimley, Surrey, UK) noticed
that the central peak of Aristarchus was quite bright and extended to a
circular region in the east in the crater "sprout" area - Cameron
suggests that this is Bartletts self defined EWBS area?. Beyond the rim

On 1978 May 24 at 00:40-01:05UT P. Moore (Sussex, UK, and using a
12.5" reflector at x300-400 - seeing IV) saw colour in Aristarchus (red
on the south east wall and southern "horn" of the crater. He could not
detect colour elsewhere, but felt that the effect might have been
spurious colour. With the increasing altitude of the Moon the light
effect decreased. Moore detected red the next night as well (May 25th)

On 1990 Jan 14 at UT 01:14-01:55 M.C. Cook (Frimley, UK, seeing=poor)
observed that Aristarchus did not appear normal for this illumination.
the northern half of Aristarchus was "2x>" than the southern half of
the crater. There were two white patches of apron material near to the
crater Herodotus that were 50% of the brightness of the southern half
of Aristarchus. Furthermore the southern half of Aristarchus had a
circle - "dull patch on inner S wall with a bright point shining
through it. (Bartlett's EWBS?)". The Cameron 2006 catalog ID=389 and

On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9
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.
Near Kepler 1966 Dec 31 UT 03:00? Observed by Petrova,

wrong as the Sun is ~7deg below the local horizon at this time.
ALPO/BAA weight=1 to reflect this error.
Aristarchus 1957 Oct 13 UT 07:00?$ W.Haas, according to the 1978
NASA Catalog is supposed to have seen a bright spot of light --
"explosion" in this crater. Confirmation of activity
in Aristarchus - Three independent observations within 4 hours.
Cameron 1978 catalog weight=5 and TLP ID No.=676. Private
comunication with Haas shows that he recorded nothing unusual
on the 12th or 13th. Therefore an ALPO/BAA weight of 1 has
been given until this matter is cleared up.
Fracastorius 2022 Apr 21 UT 01:35-02:12 A. Amorim (Brazil -
90mm f/10 refractor, 25 & 10mm eyepieces ) observed visually a
little bright spot near the centre of the otherwise completely
shadow filled crater. The bright spot was surrounded by a coma
effect. Clouds intervened but by 02:12 the spot was no longer
visible, just a thin patch of light close to the crater's
centre. Observations started when the Moon's altitude was 15
deg and ended when it was 23 deg above the horizon. ALPO/BAA
weight=1.
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.

On 2009 Sep 09 UT23:31:43 P.Grego (St Dennis, Cornwall, UK, seeing II-
III) suspected a flash south of Cabeus, just beyond the terminator.
It was not bright, and lasted a fraction of a second. Thinks it might
have been illusory as he saw some fainter flashes (cosmic rays?)
during that nights observing session. ALPO/BAA weight=1.
On 1983 Jan 05 at UT22:00 P. Madej (Huddersfield, UK) noticed some
colour on Aristarchus. The Cameron 2006 catalog ID=195 and the weight=

O.G., x100, seeing tremourlous but definition improving over time)
noticed that the central peak(s) in Alphonsus were brightening
gradually. No effect was seen earlier at UT23:30-23:35. One presumes
that the effect also occured between these two observing times?
The observer suspects that this was not a TLP, but is uncertain.
ALPO/BAA weight=1.
On 2009 Sep 11/12 UT23:28-00:00 M.C. Cook (Mundesley, UK, 90mm Questar,
x80 and x190, seeing II and transparency moderate-poor) observed
pink on the north west rim of Tycho and green-blue on the inner
SW rim. No sign of colour elsewhere on the Moon except for the
S-E rim of Plato that was red. The Moon was about 20 deg in altitude
at the time. The effect had gone by the end of the observing period.
A simulation of spurious colour in different directions
was generated by the BAA Lunar Section and found to possibly account
for these colours, although there should have been some strong colours
seen elsewhere in Tycho and none were. The BAA/ALPO weight=2.
UT 08:30 or UT 20:30? SW inner wall of Aristarchus was intesnity

4. The ALPO/BAA weight=2.
Two observing times are given for two observers, 10:30-11:07 UT and
10:45-10:52UT. Castle (Rock Island, IL, USA, 8" 51x and 102x reflector)
found that the Proclus region was brighter than the rest of the
Earthlit region. They used averted vision at x102 and noticed that
Proclus was the brightest object in the center of a glowing area. The
size of the glowing area was three times that of the diameter of
Proclus in the E-W direction and 4-5 x the diameter in the N-S
direction. East of glow was not so well defined. Darling (Sun Praire,
WI, USA, 3" reftactor x56) noticed a brightening in the Earthshine in
this region and alerted Brit. but they were clouded out.Cameron 2006

catalog ID=442 and the weight=4.
Five observers saw the upper horn split in two then a flaming torch
sprang up. Body of the Moon throbbed and withered, twelve times. Then
it took on a blackish hue. Hartung thinks it was due to an impact.
Giordano Bruno crater on the far side was a suspect until it was proven
to be too old. Cameron suggests that it might be related to
atmospheric aberration near the horizon. ALPO/BAA catalog weight=2.

On 1983 May 15 at UT21:30-22:30 M.C. Cook and J.D. Cook (Frimley, UK)
could clearly see Aristarchus in Earthshine, whereas earlier that night
P.W. Foley (Kent, UK) could not see the crater although other features
were cisible. The Cameron 2006 catalog ID=215 and the weight=2. The

On 1991 Dec 09/10 at UT 23:53-00:12 D. Darling (Sun Praire, WI, USA,
3" refractor, x36) witnessed a flash in Grimaldi crater. Cameron
comments that others had seen a flash there earlier, and there was a
meteor swarm. Fritschel (madison, WI, USA, naked eye observing)
detected 3 flashes in Grimaldi and also at the western limb of the
Moon. D. Weier (Sun Praire, WI, USA, 3"refractor, x36) was also
observing. The Cameron 2006 catalog ID=436 and the weight=5. The

Aristarchus 1971 Oct 22 UT 19:43-19:56 A.Mackay (Hatton, UK, 15cm
reflector, x50) observed a pale pink on the W(IAU?) half of
Aristarchus and a pale shade of blue on the E(IAU?) half. The
effect faded from 19:56UT onwards and had gone 2 minutes later.
No information on whether other craters exhibited this effect,
given. Burgess, who observed later did not see any colour.
ALPO/BAA weight=1.
On 1980 Apr 16 at UT 20:00-22:20 P.W. Foley (Kent,UK, 12" reflector,
seeing II-III) found that Aristarchus could barely be seen. Therefore
it was not possible to take CED brightness measurements. Strangely
Cassini, Kepler, Plato and Mons Pico could be seen. However at
20:16 UT St Elmo fire-like flashes were seen coming from the interior
south east corner of Aristarchus at 20:16 UT and then the brightnesss
spread to fill the rest of he crater. Duration was about 5-20 sec
(Cameron comments: atmospheric effects?). The crater reached peak
brightness at 20:17UT (CED reading of 8). Foley comments that the
crater rim and area 16-24km around this (including Herodoyus) had a
translucent radiance. However at 20:25UT the brightness reduced
(including Herodotus) down to CED 3, however the blue radiance
remained. At 21:07UT Foley saw a star-like flash in the south east of
the floor (CED 3-4). Grimaldi was found to be of constant brightness by
comparison using the CED Brightness=2). At 20:20UT Amery (Reading, UK)
found Aristarchus to be a well visible circular fluorescent patch. At
20:40 Amery found the region between Aristarchus and Herodoutus was
glowing - appeared almost as a flare from Aristarchus and by 20:55UT
there was also a flare to the west of Aristarchus. At 20:27 Madej
(Huddersfield) detected only a slight glow from Aristarchus and the
region affected was small - indeed the glow had gone by 20:46. At 20:40
Ricketts detected a "continuous blue emission" - this had a cycle of 5-
10 sec (Cameron comments: atmosphere?). Saxton (Leeds, UK) detected at
20:42 "translucent effects and variations" at 20:42 noticed a star-like
point. At 19:00-21:40 M. Price (Camberley, UK) decided that Aristarchus
was fainter in brightness than normal. Peters observed a faint nebulous
spot at at 20:25-21:00 that changed in brightness in an irregular way.
Cameron 2006 catalog ID=86 and weight=5. ALPO/BAA weight=3.
1837Mar11 UT 15:27 (20:48 local time) T.G. Taylor (Madras,
India) whilst observing a star being occulted, noticed a
6th magnitude nebulous spot where Aristarchus should be. Had
never seen anything quite as bright as this on previous
occasions (except the day before). ALPO/BAA weight=2.
On 1981 Jun 07 at UT02:30-03:00 B. Hobdell (St Petersberg, FL, USA,
10" and 4" reflectors, seeing=I) at 02:30UT saw a flash from
Aristarchus and another one from Schroter's valley. By 02:45UT
Aristarchus was starting to be difficult to see and had occasionally a
bluish cast. By 03:00UT the crater could only barely be seen. This was
odd because visibility on the Earthlit side was really rather good. The
Cameron 2006 catalog ID=143 and weight=0. The ALPO/BAA weight=1.
On 1981 Jun 07 at UT02:30-03:00 B. Hobdell (St Peterberg, FL, USA, 10
and 4" reflectors, seeing=1) saw Copernicus to be very bright in blue.
Clarty of Earthsine was exceptional tonight. The Cameron 2006 catalog
ID=143 and weight=0. The ALPO/BAA weight=1.
W.limb 1983 May 16 UT 22:00-23:00 R.Moseley (Coventry,UK, 6"
reflector, x60) observed a faint but extensive brightening of
the W.limb, perhaps a little stronger at PA=80-90 deg. No other
features seen in Earthshine although Aristarchus suspected.
ALPO/BAA weight=1.
Atlas 1968 Dec 24 at UT 09:15-10:45 Osawa (Kyoto-Ken, Japan, 8"
reflector, 9mm Ortho, Seeing=5, later worse) saw a slight
brownish hue on the northern shadowy bed in the crater. It was
difficult to see the difference between the glow and chromatic
aberation of the eyepiece. The tint never showed up in filters.
The ALPO/BAA weight=1.
On 1980 Apr 19 at UT 20:37-20:49) P. Madej (Huddersfield, UK,
77mm refractor, x83 and x111) at 20:37 UT saw a slight glow at
x83, quite small in size. At 20:46UT no glow was seen at x83.
At 20:49 a slight glow seen again, but unclear and
illdefined - appeared larger in area at x111. Observatons
ceased at 21:56 dues to clid. ALPO/BAA weight=1.
On 1980 Apr 19 at UT20:30-22:59. The following is quoted from the
Cameron 2006 catalog.... "(Buczynski) alerted by colleague (Greenwood)
who used filters W15 (IR), W25 (red), W44A (blue), & W58 (UV) and had
located a possible blink in it. (Bucz) used W15, W44A & W25. C.P was
very bright in W25 (red), dull but vis. In W44A (blue) & floor was
noticibly darker in W44A than in W25. Bright cp vis. In W15 & floor was
of a light shade. Other craters checked for color, none found. In 44A
floor lost some definition (gas?). Sketches from Bucz. & Greenwood.
(Pedler) at 2140, floor area around cp was seen in white & red as
normal but blink was vis in white, darker in blue. Checks of other
features were negative. (Amery) small dark center & small dark area -
not shadow - under S wall. N wall obscured by dark area extending N
onto surrounding mare. (normal?) which was difficult to focus (gas?).
At 2155 N wall now sharper & dark area less intense. Craterlet Cameron
in N wall clearly seen which was invisible 1/2 h earlier. (Saxton)
whole crater flashed and blinked at 2155. Could see detail in brighter
W 1/2 of crater - not seen earlier. At 2205 seeing poor, at 2215 it was
normal. (Blair) at 2155 used red & blue filters & in blue it was darker
than in red. W. wall not well defined. (J. Cook) saw spurious color on
N & S rims. Saw a pink tinge on SE rim. (A. Cook) saw spur. Color on
most craters as seeing deteriorated. Got a blink on SE region > red
than blue". The Cameron 2006 catalog ID=87 and the weight=5. The
ALPO/BAA weight=3.
In 1879 Oct 20 UT 23:00 (Local time Oct 21 9AM) Hirst (Blue Mountains,
NSW, Australia) saw a large part of the Moon covered with a dark shadow
that was as dark as the Earth's shadow would have been if there had
been an eclipse. Cameron says that this is a confirmed observation.
Note that the Moon was just before first quarter. The Cameron 1978
catalog ID=215 and the weight=4. The ALPO/BAA weight=3.
On 1969 Nov 15 at UT 02:20-03:20 Lagunas (Santiago, Chile, 10"
reflector) observed some brightenings in Aristarchus during the Apollo
12 watch. The Cameron 1978 catalog ID=1209 and weight=0. The ALPO/BAA
weight=1.
On 1980 Apr 20 at UT 19:25-23:43 P.W. Foley (Kent, UK, 10" reflector,
seeing II-III) found that Aristarchus was very bright in Earthshine
(also found on the photographs that he took), giving off a blue
"incadescence", the CED brightness reading was 5. Occasionally Foley
could see a star-like point in the south east corner. For comparison in
brightness he used highland terrain near to Grimaldi (CED=2). By
comparison, Buczynski and Lord, could not see Aristarchus. Earlier,
Geenwood saw the crater easily as a star-like point with a diffuse
exterior glow. Cameron says thyat this was confirmed by Buczynski and
Lord (?). At 20:35UT Amery decided that Aristarchus looked brighter
than normal. Pedler though described the crater as "small dim nebulous
blue or blue-green" that was invisible by 20:27UT. At 20:28-22:01 Blair
could not detect Aristarchus, nor could J-H Robinson at 20:40UT though
he did see it at 20:55UT as both diffuse and blue. Ricketts detected a
blow glow with irregularly spaced flashes of roughly 5-10 sec apart.
Cook's at Frimley, UK, saw no features in Earthshine. Cameron 2006
catalog ID=88 and weight=4. ALPO/BAA weight=2.
On 1983 May 17 Foley (Kent, UK, 12" reflector)observed
Aristarchus at 22:10 and noted that it had the same rose-violet colour
as had been seen by him a day earlier. The Cameron 2006 catalog ID=220
and the weight=0. The ALPO/BAA weight=2.
On 1988 Nov 14 at UT 17:25-18:30 H. Miles (St. Minver,
Cornwall, England, UK, 5"refractor? x60 and x120) found
Aristarchus to be a white ill-defined circular patch. At
17:45UT it was a lot brighter (Cameron comments that this
might have something to do with sky darkness). In contrast,
Copernicus was just seen as a white patch and the Jura
mountains could be seen (not as bright). Aristarchus grew
brighter over time and there was a bright point on the west
wall (seen at x60 and x120). Īt was fainter at 1854 & < At
1830. (Foley) said Earthshine cond. Superb with many regions
clearly seen, but Aris. was dull. (Cooks) in hazy condition
could not detect Aris." The Cameron 2006 catalog ID=338 and
weight=0. The ALPO weight=1.
Daniell 1979 Apr 02 UT 21:45-22:14 Obseved by Madej (Huddersfield, UK,
158mm reflector, f/4.2, x36-110, seeing II-III) "Obscuration seen" BAA
Lunar Section Report. Cameron says that this was a bright white cloud
that covered three quarters of the crater. A yellow filter was used at
21:48, but the cloud was still white, albeit thinner (at x110). By
22:14UT the TLP was barely visible and again no colour seen. Buczynski
(Lancaster, UK, seeing = poor) saw spurious colour. Later (22:31-
22:46UT?) Mellor obtained some photos, but these revealed no colour.
The Cameron 1978 catalog ID=48 and the weight=3. The ALPO/BAA weight=2.
On 1980 Apr 20 at UT 19:45-22:45 M.C.Cook (Frimley, UK) - colour
(probably spurious) seen on Piccolomini. Cameron 2006 catalog ID=88 and
weight=4. ALPO/BAA weight=1.
On 1980 Apr 20 at UT20:05-21:02 J.D. Cook (Frimley, UK, 12" reflector,
x60, seeing III-IV) at the start of this session found some bright
spots in the area of Copernicus, and at 21:02 detected some flashes in
this region. Cameron 2006 catalog ID=88 and weight=1. ALPO/BAA
weight=1.
On 1983 Jan 19 at UT 18:00-19:00 G. Amery (Reading, UK) discovered that
Aristarchus could not be seen in Earthshine, this was odd because less
prominent features could be seen. Other observers (Moore and Foley)
confirmed the very low brightness of the crater. The Cameron 2006
catalog ID=197 and the weight=2. The ALPO/BAA weight=2.
On 1983 Jan 19 at UT 18:00-19:00 G.W. Amery (Reading, UK) found that
Messier was difficult to define. The Cameron 2006 catalog ID=197 and
the weight=2. The ALPO/BAA weight=1.
On 1980 Apr 20 at UT20:27 M.Price (Camberley, UK) saw a flash in the
Grimaldi-Aristarchus area. Cameron 2006 catalog TLP ID=88 and weight=4.
ALPO/BAA weight=2.
On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teignmouth, UK, 10.5"
reflector, x180) found, using a Moon Blink device, evidence of colour
on the flor patches of Fracastorius crater, brighter in blue than in
red. Also the floor to center varied in brightness in blue and in red.
Peters observed in white light and found the south east-south wall had
a slight orange cast and when a Moon blink was used it was less bright
in blue than in red light. M. Cook found spurious colour on the south
rim and also on Mons Pico. There was a colour blink reaction on the
southeast floor of Fracastorius - this was both faint and blurred and
not seen in white light. A.C Cook detected the permanent blink in the
south east floor of the crater at 21:47 and a fainter one in the north
west (marginally brighter in red than in blue). J.D. Cook found no
colour with the Moon blink device. 21:22-22:10 P.W. Foley got a strong
colour reaction with the Moon Blink device - brighter in red than in
blue and detected a pink colour visually on the south east wall 22:10-
22:45 (this did not give a blink effect though). Cameron 2006 catalog
ID=88 and weight=4. ALPO/BAA weight=2.
On 1980 Apr 20 at UT21:38-21:50, Blair of Renfrewshire, Scotland (used
an 8" reflector and seeing=III) saw three patches in Petavius and they
could still be seen 7 minutes later. At 21:50UT he used a filter and
found the "northern one was brighter in blue, the southern one was
brighter in red and the central one was the same shad ein both
filters." Cameron comments that the central patch was a permananent
one. She then goes onto say that the crater is described as having dark
patches that are opposite to what one would expect from Fitton's theory
applied to dark features. Cameron 2006 extension catalog ID=88 and
weight=4. ALPO/BAA weight=2.
Linne 1867 Aug 06 UT 21:00? Observed by Buckingham (England?)
"Crater in darkness, he saw a "rising oval spot". Other obs.
saw it as a triang. Bold black spot pointing to earth, slowly
diffused white & drift of white on slope of pyramid. (indep.
confirmation?)" NASA catalog weight=5 and catalog ID #155.
ALPO/BAA weight=2.
Apianus D On 2011 Oct 03 UT 21:00-21:20 F. Power (Meath,
Ireland, 11" SCT) observed changing colours (blue, white, and
red) on the inner western rim of this crater. He changed
eyepieces and moved the scope around to look at dufferent parts
of the Moon, but nowhere else exhibited anything similar. As
another test he asked his wife to have a look without telling
her what he was seeing. She confirmed the same effect. 5 digital
camera images had been taken. Most of these were out of focus
and the first one was saturated, however one of them showed a
approximately 35 km long, by 11 km wide (at the north) lopsided
carrot shaped orange colour to the western rim of Apianus D. No
similar strong colour could be seen anywhere else on the image,
nor on the other 4 images. This TLP is being given an ALPO/BAA
weight of 1 as the Moon was low, but an image taken looks
interesting.
On 1988 Nov 15 UT 19:15 Holmes (Rockdale, UK, 215mm Newtonian) noticed
the Censorinus apron (just east of the crater and including the rim)
was fuzzy but the crater was clear - a sketch was provided. A BAA Lunar
Section observation.Cameron 2006 Catalog Extension ID=339 and weight=3.
ALPO/BAA weight=3.
On 2001 Apr 29 at UT 20:50 R. Braga (Italy) reported that without any
filter, the brightness of the east wall of Torricelli B was halfway
Torricelli C (faintest) and Moltke (brightest). By insering a Wratten
25 red filter though, the crater was slightly more evident. However
using a blue Wratten 39A filter, the crater vanished completely, whilst
Toricelli C remained. The ALPO/BAA weight=3.
Near Ross D (24E, 11N) 1964 Mar 21 UT 05:00-06:20 Observed by
Harris, Crow, Cross (Whittier, CA, USA) - negative confirmation
from Las Cruces. NASA catalog weight=0 (unreliable). NASA catalog
ID #805. ALPO/BAA weight=1.
On 1983 Mar 21 at UT 21:05-22:00 P. Horne and J. Horne (Hertz, England,
UK, 11" reflector, x180 and x330) found that Mons Piton (totally
illuminated and brightest feature on the Moon - but no variability) was
brighter than Aristarchus (would have been if it had been in sunlight)
and the mountain was contained within a circular illuminated patch.
"Brilliant white and no shadow. Size ~16km." There was no details
visible but the adjacent features had distinct shadows. Hutton was also
observing. Foley examined the photographs and believes that they are
inconclusive. D. Mansbridge was photographing the Moon at 19:30UT and
detects Piton but it is not bright. However in a photograph taken by D.
Mansbrdige and 20:30UT the mountain is much brighter than any other
sunward facing slopses on the northern part of the Moon's terminator.
R. Mosley had been observing earlier at 18:10-19:40 and although
finding the mountain to be shining briliantly beyond the terminator, he
also comments that this is normal. Cameron though has seen the
photographs taken and thinks it might be a real TLP. The Cameron 2006
catalog ID=208 and weight=5. The ALPO/BAA weight=2.
On 1988 Nov 16 at UT 18:20 M.C. Cook (Frimley, UK) observed that a ray
north east of censorinus appeared to be very diffuse and this did not
change during the observation. This was odd because proclus ray
material remained clear. The apron material of Censorinus was diffuse
E-W and the northern part was dull, but not fuzzy. The Cameron 2006
catalog ID=340 and the weight=3. The ALPO/BAA weight=2.
On 1988 Nov 16 at UT 18:20 M.C. Cook (Frimley, UK) observed that
Torricelli B changed in brightness (at times), but thinks that this was
due to atmospheric transparency. The Cameron 2006 catalog ID=340 and
the weight=3. The ALPO/BAA weight=1.
On 1984 Apr 08 UT 19:50 Mobberley (14" reflector, x194, seeing
III-IV, Transparency Fair-Poor, Cockfield, UK) found that
Torricelli B's shadow was 1/2 the way across the floor, which
was normal, but that there was a very dar grey/brown shroud
around the carter, out to several radii.
The ALPO/BAA weight=1.
Ptolemaeus 2020 Feb 01 UT 19:40-19:50 P. Sheperdson (York, UK,
102mm Mak - BAA) saw an "ashen" sliver of bright light across
the floor. Images taken. This maybe normal appearance - though
observer re-observed in May and found the effect different in
that there was no "ashen" like effect. Visual sketches and
time lapse image sequences welcome. If doing visual work - try
using a polaroid filter and rotate it to see if that makes any
difference. For imaging work, please over-expose slightly to
bring out detail on the floor; you could also try colour
imaging of the floor as an interesting experiment - though for
comparison purposes image other terminator features exhibiting
shadow spires. ALPO/BAA weight=1.
On 1980 Apr 22 at UT20:30 R.Rohslberger (Hittfield, (near Hamburg) West
Germany, 8" reflector, x170 25mm occular used, 300mm focal length?)
took some photographs using projection. One of these recorded an
apparent "ejecta curtain". Cameron considered lens flare, but the other
photographs did not show this. If real then the plume was at a height
of ~40km and the ray was ~130km. Cameron concludes that this was an
impact photograph. The Cameron 2006 catalog ID=90 and the weight=5. The
ALPO/BAA weight=3.
Alphonsus 1952 Nov 24 UT 18:00 A.P. Lenham (Swindon, UK, 3-
inch efractor x120) noted that the usual dark spots were not
visible, but floor ridges and craterlets were surperbly seen.
This may not be a TLP but has been given a TLP category as it
is a curious appearance and needs to be verified on a repeat
repeat illumination apeparance. ALPO/BAA weight=1.
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.
Dome W. of Manillius 1965 Dec 30 UT 10:35 Observed by Newport (England,
4" refractor x180) "White patch or haze, everything else was sharp"
NASA catalog weight=3 (average).
On 1987 Jan 07 at UT19:10-20:30 H.Miles of Cornwall, UK saw two bright
patches were seen in Earthshine at clock positions of 4 (this patch was
defined by the dark limb and the brightness faded inwards to the disk,
over a short distance. "Centred at 60 deg along the limb from the north
- a sketch showed approximately 10-15 deg along it") and 5:30 (this
second patch was smaller and not so bright as the first patch - it was
west of the north pole. P. Foley (Kent, UK) also detcted the patches
and said that one was not far from the sunrise terminator.
The Cameron 2006 Extension catalog gives this TLP an ID of 291 and a
weight of 2. The ALPO/BAA weight=2.
On 1953 Sep 16 UT03:00 R.M. Lippert (San Diego, CA, USA, 20cm
Cassegrain reflector, x90)saw a bright magnitude 1 flash on the
Moon, that was probably on the east rim of Werner(?) crater. It
is unclear if the observer meant it was really magnitude 1, or
was what a magnitude 1 star would have looked like. The flash
was yellow-orange in colour. Observation described in the
"Observations and Comments" column in the December, 1953
Strolling Astronomer (Vol. 7, No. 12), on page 170. The ALPO/BAA
weight=3.
Plato 1789 Jul 30 UTC 21:00? Observed by Schroter (Lilienthal, Germany)
NASA Catalog Event #61, NASA Weight=2 (slightly low) Event described
as: "Soon after sunrise saw a kind of fermentation on the floor which
clearly resembled a kind of twilight, (due to some kind of aberration
unknown to the observer?)" For further details see reference:
Middlehurst, B.M., Burley, J.M., Moore, P.A. and Welther, B.L., 1968,
NASA TR R-277.
Eratosthenes 1952 Nov 25 UT 16:30 A.P. Lenham (Swindon, UK, 3-
inch refractor x150, Definition Good) noted that there was
faint/slightly bright detail inside the interior shadow -
observer comments "presumably peaks of central mountains & W.
Wall ridge, but very faint" - however this is worth checking
out. ALPO/BAA weight=1.
On 2009 Nov 25 UT18:42-21:03 P.Abel, T.Little and C.North (Selsey, UK,
15" reflector, seeing II-III, transparency very good), all saw visually
a brownish tinge on the north west rim of Eratosthenes crater. P.Abel
made a sketch and T.Little took some high resolution CCD images, some
of which were through coloured filters. Checks were made for spurious
colour, but none was seen elsewhere on the Moon. The eyepiece was
changed but this made no difference. M.C.Cook (Mundesley) was observing
with a smaller scope at the same time, but saw no colour, however
observing conditions were worse. W.Leatherbarrow (Sheffield, UK) was
observing with a instrumenet mid way in size, and saw a brownish tinge
in the NW rim area, but saw a similar colour elsewhere and put this
down to spurious colour. Normally multiple observers seeing the same
thing would result in a weight of 4, however as this was only observers
at Selsey and some of the evidence contradicts, I am allocating an
ALPO/BAA weight=3.
Pallas-Schroter 1953 Nov 13 UTC 02:00 Observed by L.Stuart (USA)
"Saw and photographed a bright spot on term. between these two
craters. Used Kodak 103aF3." NASA catalog weight=5 and catalog
ID #559. ALPO/BAA weight=5.
On 2012 Aug 25 UT1944-1952 Eratosthenes crater was imaged by C.
Galdies (Malta,Nexstar 8SE, Philips SPC 900NC camera). 4
Registaxed images were produced covering 19:45, 19:48, 19:49,
and 19:51. All but the first image, once first order spurious
colour had been removed, showed orange on the shaded terraces on
the western illuminated rim (similar to what Paul Abel and
others saw in 2009, albeit just confined to the NW rim), and the
interior floor shadow was slightly smaller in red light. However
orange colour was also seen on the eastern side of mountains to
the south of the crater, which infers that the spurios colour
removal did not fully acomplish its main goal. The effects were
not caused by the registax software as the orange colour is
visible on individual images. Although probably the colour is
not lunar in orgin, its explanation is not fully explaianed,
therfore an ALPO/BAA weight of 1 is used for now.
On 1969 Nov 18 at UT 04:22 Loocks (Valparaiso, Chile, 12" reflector)
observed a flash of light of magnitude 12. Cameron speculates a meteor
and mentions the apollo 12 watch. The Cameron 1978 catalog ID=1214 and
weight=1. The ALPO/BAA weight=1.
North (?) (left) Cusp 1912 Jan 28 UT 00:00 (27th 20:00 L.T.) Observed
by Harris (Philadelphia? Pennsylvania?, naked eye?): Intensely black
curved object 400x240km, shaped like a "crow". Cameron 1978 weight=1
(very low) and ID=334. ALPO/BAA weight=1.
Eratosthenes: On 2017 May 04 UT 21:50-22:10 N. Longshaw (BAA,
UK, 78mm APO refractor, x125 & x175, seeing II-III,
transparency Good). A brownish (orange) tint was seen on the
inner NW wall light terraces - this was immediately obvious
when first looking at the crater, but as time progressed the
effect became less bright. Other craters were checked for
similar coloured tints, but none were seen elsewhere on the
Moon. UAI observers in Italy (F. Taggogna & A. Tonon) had been
imaging the region in colour 17:57-21:47, but their images do
not show any colour on the inner NW rim terraces, the their
last image is 3 min before Longshaw saw the colour. The
ALPO/BAA weight=2.
Eratosthenes 1947 Jan 30 Mean Col. 16deg. Observed by Hill (UK) "Main
peak of massive central mountain group appeared to be in a shadowless
having regard to it's claimed height of 6,600 ft. The whole of the
floor to the west should have still been in darkness. Instead
immediately to the west was a dark (intensity 1.5-2) region extending
almost to the foot of the bright inner wall and very diffuse in
outline. The observation could not be followed through due to
increasing cloud, but on the following night all was normal."
On 1886 Jun 10 at UT 21:00 (estimated) Tempel of Germany, saw a star-
like light (Cameron comments that the reference in the Middlehurst
catalog is wrong). Cameron 1978 catalog ID= and weight=4. ALPO/BAA

On 1980 Apr 24 at 23:35UT Marco Petek (Porto Alegre, Brazil,
using a 7.5" refractor noticed that the center of Plato was
bright and opaque and the observer thought it was similar in
appearance to Linne. A sketch was made and two other observers
confirmed the appearance. Cameron mentions that Petek is an
experienced observer. Cameron 2006 catalog extension TLP ID=91

25cm reflector, x250 & x380, seeing good but with some cloud)
The interior W. wall of this crater (on the lip) appeared
hazy - difficulkt to bring detail into focus. Neighbouring
craters/detail were sharp. Details in the crater wall interior
