On 1982 Dec 27 at UT 23:00 M. Price (Camberley, Surrey, UK, Seeing=III
and transparency=good) observed that Piazzi-Smyth was brighter than Mon
Piton at 23:00. Photographic atlas was checked to verify that this was
abnormal. The Cameron 2006 catalog ID=193 and weight=4. The ALPO/BAA
weight=2.
Moon 1967 Apr 22 UT 02:30 Observed by Dunlap et al. (Corralitos
Observatory, Organ Pass, NM, USA, 24" reflector) "UV excess as in #
1029. Gradient was 10# at term. to 25-30$ at subsolar pt. (153 deg
long)." NASA catalog weight=5 (very high). NASA catalog ID #1031.

On 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st
7:24PM PST) saw a naked eye flash on the Moon. The observers were
glancing up at the Moon in daylight when they saw a bright white flash
(observer and his wife together) in the upper/mid Mare Serenitatis
region, west of the crater Posidonius. "Larger than how Venus appears".
"It was a quick flash like white, intense lightning. I'm not sure how
to report degrees of arc but if the face we see is 900, and we start
from the east then the flash occurred about 225 arc seconds to the
west. This was observed by the naked eye, with clear skies between us
and the moon." The observers checked for signs of aircraft vapour
trails but could not see any. There is a possibility that it could have
been sun glint from an Iridium satellite, but this needs to be checked
out and usually these last longer than the observed effect. It would be
useful to obtain whole Moon images under the same illunination and
libration so that we can judge this observation properly. The ALPO/BAA
weight=4.
Herodotus 1965 Jun 11 UTC 21:35-21:40 Observed by Porta, Garau

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 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW,
Australia, 8" reflector, x100, x160, S=III) observed a bright star-like
point on the western (IAU) edge of Mare Tranquilitatis (x100) that
appeared unlike any other crater and a check of the location revealed
no suitably bright crater in that region (from a map?). Changed to a
higher power (x160) and it was still there, but not as conspicuous.
Observer thinks that this may have been due to the Moon's low altitiude
(16 deg) and the seeing. At 18:35 he compared it to the brilliant
crater Proclus and found the star-like point to be 75% of the
brightness of Proclus. Ken Wallace (Australia) had been taking photos
and observed the object at 17:37.5UT. The object gradually faded over
the next 15 minutes and by 18:52UT could only be seen in averted vision

On 2000 Jan 21 UT04:40 G. Emersen (Golden, CO, USA, 30cm focal length
lens with Wratten 25 ref filter) took 43 CCD images of the eclipse of
the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively
bright spot appeared in the southern part of Mare Fecunditatis. The
spot looks sharper than the rest of the Moon and so might be a cosmic
ray? CCD images taken from Washington D.C. by A.C. Cook at this time,
do not show this spot, however exposures were at intervals of 0.25 sec
and so might have missed this spot if it happened during image readout.

of light of low brightness was seen to move around the north polar
area. Coloured bands were also seen on the Moon.
On 1848 at UT 21:00 Rankin and Chevallier (France?): Luminous pts. seen
during an eclipse. Cameron ays that year 1847 given by Middlehurst must
be wrong as age is 2.7 days for this date in 1847 and could not be 18-
19 as in Middlehurst because eclipse is on the 19th at 21h (mid) in
1948. aux. data here are for 1848. At 21:12 Forster (England) and

Aristarchus was glowing with brilliance never seen before. This
attracted everyones attantion. It extended its radiance to adjecent
craters (e.g. Herodotus) all throughout totality. At the subsequent
eclipse in September 1895 it was seen to be inconspicuous. the Cameron
1978 catalog ID=283 and the weight=5. The ALPO/BAA weight=4.
Moving glows seen around the middle of the
disk during a lunar eclipse.
On 1888 Jan 28 ~UT 23:20 Dyer observed that in this fairly bright lunar
eclipse was a dark isosceles triangle, with the base to the north.
Other observers noted this effect.
On 1891 May 23 at 18:36-19:15 UT, Jackson of Sheffield, England, using
a 6" refractor, saw "1/2 hour before the end of a totl eclipse, a
region of the crater and just north of it, become conspicuous and
increased in brightness from then on" Cameron thinks this is just the
edge of the shadow and possibly normal. Cameron 1978 catalog ID=268 and
weight=0. ALPO/BAA weight=1.
In 1954 Jul 16 at UT 01:12 Chernov (Russia, 2" refractor, x33) observed
the following for Aristarchus: "Activity noted in it * in extension of
Moon's shadow on sky for 12 min during .17phase of ecl.(source gave
date as June 16, but ecl was July 16)". The Cameron 1978 catalog ID=566

Kepler 1967 Oct 19 UTC 05:00 Observed by Classen (Pulnitz Obs. East
Germany, 8" reflector) and Corralitos Observatory (Organ Pass, NM, USA,
24" reflector + moonblink) "It was 1 mag brighter than aristarchus when
normally Aris. is 0.3mag. brighter than Kep. Corralitos MB did not

On 1906 Feb 08 after a lunar eclipse, Frost and Stebbins determined
that Linne had enlarged by 1" in size.
On 1967 Apr 26 at UT 03:00 Kozyrev (Crimea?, Soviet Union) observed Gas
luminescence in Aristarchus crater. The Cameron 1978 catalog ID=1069
and weight=3. The ALPO/BAA weight=3.
On 1977 Oct 28 UT 19:25 V.M. Chernov (Soviet Union) observed that
Copernicus was brighter than normal i.e. brighter than Kepler but less
bright than Aristarchus. In January and February 1977 both Copernicus
and Kepler were of the same brightness. The ALPO/BAA weight=1.
Plato 1869 Aug 23/24? UTC 23:00-01:00? Observed by Gledhill? (Halifax,
England, 9" refractor) Group I of craterlets (as designated by several
famous obs. before) exhibited notable illumination, accompanied by a
single light on a distinct spot. (if obs. similar to Ap 1870 obs. then
date =Au 23-24). NASA catalog weight=2 (low). NASA catalog ID #162.
In 1954 Jul 17 at UT06:50-07:15 Bartlett (Baltimore, MD, USA, S=

Messier A 1951 Aug 20 UT 01:48-03:00 Observed by P.Moore
(England, 8.5" reflector, x350). Bright cloud like circular
patch seen on S wall of Messier A. It was the brightest object
in the vicinity. Observations ceased due to the Moon setting
behind a tree. W.Haas thinks that this effect is not unusual at
similar colongitudes. Moore checked again under similar
illumination and still considers the Aug 20 appearance abnormal.
NASA weight=4. NASA catalog ID #545. ALPO/BAA weight=2.
Plato 1938 May 17 UTC 08:00 Observed by Haas? (New Mexico?, USA,
12" reflector?) "Floor-least bit greenish (other colors on other

(average). ALPO/BAA weight=2. NASA catalog ID #437.
Cleomedes 1991 Dec 23 UTC 22:50 Observed by Mizon (Colehill,
Dorset, UK, 8" f/6 reflector x216) "Oval or pear-shaped ashy
glow visible for 2 min, then vanished quite suddenly" - Ref.
personal communication received by BAA Lunar Section.
Proclus 1973 Jan 21/22 UTC 23:57-00:25 Observed by Muller (located at
51.42N 8.75E) "Proclus much brighter than Cenorinus" 50mm refractor
used. Ref Hilbrecht & Kuveler (1984) Moon and Planets Vol 30 p53-61.
On 1979 Sep 09 at UT08:00-08:15 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x75 and photography used, seeing 4/10 and the Moon's
altitude was 45deg) photographed Romer crater and recorded two adjacent
bright cigar shaped objects - these were the same size as an
observation made in 1987. Darling believes that these are ridges.
Cameron comments that in LO-IV 192-3,2 a ridge is revealed on the
inside wall that matches the description. Cameron 2006 catalog ID=66
and weight=2. ALPO/BAA weight=1.
On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"?
reflector, seeing III) found that Aristarchus was very bright
and slightly blue. Cameron comments that Moore's eyesight is not
very blue sensitive. The Cameron 2006 catalog ID=175 and weight=
4. The ALPO/BAA weight=2.
On 1982 Jul 09 at UT01:05-01:25 P. Moore (Selsey, UK, 12.5" reflector,
seeing=III) found that Grimaldi A was the 2nd brightest feature on the
Moon, and that there was colour detected with a Moon blink device on
the floor of Grimaldi. The Cameron 2006 catalog ID=175 and the weight=
4. The ALPO/BAA weight=3.
Plato 1877 Jul 29 UTC 02:00?-02:30 Observed by Gray (England?) "S. of
crater a bright streak that disappeared at 0230" NASA catalog weight=3
(average). NASA catalog ID #196.
Macrobius 1898 Dec 31 UTC 20:00 Observed by Goodacre (Crouch End,
England, 12" reflector) "Interior nearly filled with shadow at sunset.
Inner E.wall very bright-a distinct penumbral fringe to black shad.

On 1989 Aug 20 at UT13:55 M. Lucas (Melbourne, Australia, naked eye)
witnessed a "pin-point flash" in the middle of the lower right quadrant
of the Full Moon. Foley suspects that this was in the Proclus region?
The Cameron 2006 catalog ID=374 and the weight=2. The ALPO/BAA
weight=2.
Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK,
10.25" reflector, x250, Wratten 44a and 25, seeing II) noted
that Aristarchus was surrounded by a dark area in the blue
filter. They did not regard this as a TLP at the time. However
because Aristarchus is surrounded by blue material in real life,
this should have been brighter? For this reason, despite the
observer regarding this as a negative TLP, an ALPO/BAA weight=1
has been applied.
On 1991 Dec 28 at UT 02:10 P. Moore (Selsey, UK) could see no detail on
the floor of Plato crater. This report needs to be read in context with
the comments by Cameron for A.C. Cook's observation of the floor of
Plato on 1992 Jan 18 - Cameron 2006 catalog ID=438.
On 1916 Jan 27 at 22:00? Markov (Russia) noticed that a light sector
was visible at the bottom of Plato, in shadow, and contained 3 bright
spots, reminiscent of phfescent bodies. The Cmaeron 1978 catalog ID=362
and weight=3. The ALPO/BAA weight=3.
Copernicus 1979 Sep 15 UT04:40-05:25 J.Saxton (Leeds, UK,
8.5" reflector, x185, seeing I-IV, worsening towards local
sunrise) made a sketch and noted that the northern tip of the
internal shadow, by the floor, was not completely dark. The edge
of the floor here could be distingished, even though it was in
shadow. ALPO/BAA weight=1.
On 1979 Sep 16 at UT 08:00-09:00 D. Darling (Sun Praire, WI, USA,
12.5" reflector, x62-x97, clear, but Moon at low altitude) detected
four new features that he had not seen before in Earthsine in
comparison with what he saw on 16 Jul 1979, this time in the southern
part of the Moon. pin-point flashes were seen within these bluish
areas. Each time a flash occurred the gas clouds brightened (sometimes
by 6x) for a few seconds. Cameron thinks that these are related to
moving clouds on the Earth's limb e.g. mackeral sky. Cameron 2006
catalog ID=69 and weight=1. ALPO/BAA weight=1.
Briggs A 1980 Feb 11 UT 06:30-07:00 Observed bt Butler_FC
(Brixton, UK, 22cm Newtonian reflector, x64, x104, seeing IV).
Found Briggs A to be brownish in colour at x64, however the
colour vanished at 06:55 when x104 was used. Switching back to
x64 the colour was still there but fainter. The colour fade may
have been due to day light glare encroaching? Could not see this
effect anywhere else on the Moon but did detect what he regarded
as a permanent coloured spot (yellow) between Cruger and
Grimaldi. ALPO/BAA weight=1.
On 1824 Jan 27 at UT03:00 Gobel (Koburg, Germany) observed a reddish
colour in Aristarchus crater. The Cameron 1978 catalog ID=98 and the
weight=4. The ALPO/BAA weight=3.
Aristarchus 1969 Aug 09 UT 01:00? Observed by Hiscott
(Canterbury, 12" reflector) "Bright spots photog. on E. wall
(EWBB) (crater wall seen in ashen light at this time accord.

On 1970 Aug 04 at UT 22:50-23:30 Celis (Paso Hondo, Chile, 3"
refractor, x60, x100, x135, seeing=fair?) noted that Aristarchus was
not so outstanding tonight, but the brilliant patches had their
characteristic electric blue colour, irregular form, freq. stable.
albedo=8deg. The Cameron 1978 catalog ID=1269 and weight=1. The
ALPO/BAA weight=1.
In 1949 May 31 UT02:37 LT Johnson observed a flash near the W
limb of the Moon at the same latitude as Riccioli. No colour
seen, the magnitude was 9-10, and duration < 0.5 sec. If there
was any motion then it must have been < 24 km. He wasn't looking
at it when it happened, so the motion aspect is uncertain.
Indeed he was not absolutely certain if it was on the limb, or
just inside or outside? The BAA/ALPO weight=1.
On 1969 May 20 at UT 03:18-04:27 Cross (Las Cruces, NM, USA 6"
refractor), Olivarez (Spain?), Kohlenberger, Gibson, Miller, Duarte and
Harris (CA, USA) observed brightenings, pulsations, scintillations in
Aristarchus crater. Cameron says independent confirmation seen by 4
observers, 1-2 magnitude increases, ranged between 1-30sec. Most active
period was 03:18-03:20UT, 04:17-04:27UT (Las Cruces). Calkins (West
Covins, CA, USA) UT 03:40-04:25 saw one major brightening up 2
magnitudes above steady state lasting 0.2 to 1.5 sec and another slow
brightening lasting 5-10 seconds. Kelsey (CA, USA) saw at 03:43-03:48UT
some brightenings. These observations were made during the Apollo 10
watch. The Cameron 1978 catalog ID=1127 and 1128 and weight=5. The
ALPO/BAA weight=4.
On 1970 Aug 05 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3"

in Aristarchus (bright patches with electric blue colour) as had been
seen on Aug 04, but the intensity was less. The Cameron 1978 catalog
ID=1271 and weight=1. The ALPO/BAA weight=1.
On 1903 Mar 03 at UT 18:30 Rey (Marseilles, France) observed a star-

Ptolemeus 2020 Jul 27 UT 23:00 N. Travnik (Brazil) observed
visually for 2nd time ever (first seen back in 1970), an
effect on the floor of this crater at local lunar sunrise:
"kind of glimmering mist lifted and wafted inside the shady
hollow of the crater". Almost certainly this is a combination
of atmopsheric seeing on the narrow shadow spires, but we
would like observers to look at this visually or obtain time
sequence images to try to replicate this effect. This report
is assigned an ALPO/BAA weight of 1 for now.
Torricelli B 2002 Oct 14 UT 02:58-03:43 Observed by Gray (Winnemucca,
NV, USA, 152mm refractor x114, x305, seeing Antoniadi III, transparency
good) "I was out this morning (2:58-3:43 UT, October 14, 2002)
observing Torricelli B. At 3:17 UT the west sunlit wall of the crater
brightened from an intensity (Elger Scale) of 5.0 to 9.0. In actual
terms it went from slightly less bright than the walls of Picard to as
bright as the sunlit west wall of Dionysius. This was observed at 114x
in white light, where all three craters were in the field of view
simultaneously. This event lasted less than a minute and no comparable
brightening in Dionysius or Picard was seen. The wall of Torricelli B
returned to 5.0 in brightness. I continued to observe Torricelli B in
white light until 3:43 UT, but the brightness remained at 5.0. Before
the brightening I tried blinking Torricelli with the following
combinations of filters: Wratten Red 25 and Blue 38A, Red 25 and Blue
80, and Red 25 and Schott BG38 (Blue Green). Nothing showed up more
prominently in any combination except the Red 25-Blue 38A combination,
where Torricelli B became invisible in the Blue, probably because of
the filter density. Both the Blue 80 and Schott BG 38 seemed closer in
density to the Red 25 than the Blue 38A is. I could not see any details
inside Torricelli B during this session, including the bright spot on
the NE rim." The ALPO/BAA weight=3.

Timocharis (11W, 30N) a bright flash inside the dark area. It
appeared like a diamond twinkling in sunlight and was somewhat
dazzling to the eyes. Cameron wonders in this was a meteor?

x300) using an English Moonblink device found colour on the south west
part of the floor. Note that for the times given by Cameron, the Moon
was below the horizon from California - so possibly these are local

On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector,
seeing=III) found the region around the cleft on the souther rim to be
out of focus - however atmospheric conditions were turbulent until
23:18UT. An unsual dark triangular region (long base against rim) was
seen to extend from the inner rim at 12 o'clock onto the floor for 13-
16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK)
found the south east to soth west to be obscured again, but not as
badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the
dark region had 2 white bands on the side and the south west wall was
blurred like it was on the 20th July - this time tough colour was not
present. There were also two light patches on the floor. Mosely
(Coventry, UK) observed the south wall at x120 and found the wall out
of focus at the 11 o'clock location. Through a yellow filter he saw a
"white mistiness: on the top of the southern rim and only the south
east cleft could be seen (no colour). By 22:40-23:00 the effect had
cleared up. No dark triangular patch was seen. When Marshall (Surrey,
UK) observed (22:30-03:00) nothing unsual was seen, though a sketch
provided shows a light patch on the floor located at 11 o'clock. All
observations, made by all observers had some atmospheric turbulence,
however trsnparency was good. The Cameron 2006 catalog ID=225 and the
weight=5. The ALPO/BAA weight=3.
On 1992 May 13 at UT 20:16-21:29 several observers reported a TLP in
Plato mostly concerning the visibility of floor craterlets, however
observer seeing varied from III-V. North (UK, 18.25" reflector)
reported "Colouration and floor craterlets very prominent. Seeing
Antoniadi V, Transparancy Poor.". Foley (Kent, UK, 12" reflector
seeing=III-IV) found the floor to be bright and in the better moment of
seeing detected floor craterlets. The WNW spot was misty some of the
time. Moore (Selsey, UK, 15" reflector, seeing V) had very poor seing
conditions. J.D. Cook and M.C. Cook (Frimley, UK, 3.6" reflector,

On 1963 Nov 28 at UT 00:30-01:45 Barr, Greenacre, Hall and
Dungan (Flagstaff, AZ, USA, 24" refractor, and 69" reflector)
observed pink on the outer SW rim and a red spot towards the S of
this. A red spot was seen on the eastern side of Vallis Schroteri
but only by Barr and Dungan. Other features checked for
atmospheric spectral dispersion and chromatic aberation - but the
colours in Aristarchus were not due to these. Smaller 12" scope
checked but no effects seen - presumably due to resolution and
image contrast issues? Pink on the SW rim may have been seen in a
69" scope by Boyce and Ford. ALPO/BAA weight=4.

On 1963 Nov 28 at UT 05:00-06:00 Greenacre, Barr, Hall and
Dungan (Flagstaff, AZ, USA, 24" refractor) observed a deep violet
area form on the western exterior of Aristarchus, and a less deep
violet area form to the eastern edge of Aristarchus. As these
were becoming stronger, a blue-like haze formed on the sunlit
floor of Aristarchus, that obscured underlying detail. The

Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in
the south east corner interior of the crater Aristarchus. This colour
was confirmed by the observers wife. By 11:21 UT the colour had faded
completely. Rodway had been a lunar observer since 1958, using a wide
range of instruments from 3 inch refractors to 12 inch reflectors and
had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so
was an experienced observer. The ALPO/BAA weight=4.

reflector, x140 and 2.5" refractor) observed in Promitorium Agarum that
one of his pre-designated points, called "A", through to "C and "D" was
at least 5 brightness points brighter in red than in blue light. The
reverse was true on Sep 25th. Tonight the red seemed to be on a narrow
strip on the western edge. The Cameron 2006 catalog ID=109 and the
weight=3. The ALPO/BAA weight=3.
On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar
telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a
dusky dark gray area just north of Herodotus and just south of the
Cobra Head. The interior shadow on the east of Herodotus by comparison
wad black and distinct. No change was seen when viewed through a
rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA)
was observing at the same time but had better observing conditions and
could see detail in this region, suggesting that it was not a TLP.
There is no Cameron entry for this report. The ALPO/BAA weight=1.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi
III seeing, 12.5" reflector) "Intensely bright craterlet south of central
peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed
the crater was highly luminous at 21:20, and surrounded by a blue halo that
had a darker blue band within it. This craterlet faded over time, and by 21:20
Moore considered that it was no longer prominent, by 21:22 Foley confirmed the
reduced brilliance, and by 21:30 Moore considered it to be perfectly normal.
Moore considers the nimbus effect to be normal. The Cameron 2006 catalog ID=
306 and weight=5. The ALPO/BAA catalog weight=3.

vicinity of these two craters. ALPO/BAA weight=1,
On 1975 Mar 25 at UT18:50-20:50 P.W. Foley (Kent, UK) observed
blue/grey in Aristarchus. The ALPO/BAA weight=1.
Aristarchus 1982 Nov 28 UTC 23:35-23:55 Observed by Foley (Kent, UK,
Antionadi III, Transparency Moderate) - Colouration Seen - Ref: BAA
Lunar Section Circular. ALPO/BAA weight=2.
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
ALPO/BAA weight=1.
