On 1788 May 08/09 at UT 20:00-01:00? Mechain (France) observed bright
spots near Aristarchus. This was confirmed by Schroter and Bode
(Lilienthal, Germany, 7" reflector and refractor). The Cameron 1978
catalog weight=5 and ID=46 & 47. The ALPO/BAA weight=4.
On 1992 Apr 06 at UT00:45-02:03 G. Johnson (Swanton, MD, USA, 3.5"
refractor, x36) observed Aristarchus in Earthsine, but at a higher
magnification is appeared as a diffuse star. However the crater was not
seen later. D. Darling (Sun Praire, WI, USA, 3" refractor), D. Weier
and F. Graham (Pittsburgh, PA, USA, 7" reflector, photographs),
observing at 01:24UT could not see the crater. The cameron 2006 catalog
ID=443 and the weight=0. The ALPO/BAA weight=1.
On 1988 Apr 20 at UT02:06-03:00 D. Fryback (Madison, WI, USA, 8"
reflector, S=3-4) commented that Aristarchus crater looked like a "city
from high above "glowing under a cloud". Spain (Fairfield, KY, USA, 8"
reflector, S=VG) detected a streak and flashes but reports that the
crater was not "glowing", though it was the brightest feature in the
Earthshine, but Kepler and Copernicus were bright too. Aristarchus was
brighter in shorter exposures than in longer exposures. The Cameron
2006 catalog ID=326 and weight="confirmed". The ALPO/BAA weight=2.
On 1990 Mar 29 at UT 19:00 L. Todd (England?) observed that Aristarchus
in Earthshine was very clearly seen and appeared to blink occasionally.
Foley (Kent, UK) also notcied variations in Aristarchus. The Cameron
2006 catalog ID = 396 and the weight=1. The ALPO/BAA weight=1.
Harpalus 1969 May 19 UT 21:20-22:00 Observed by Marcomede

On 1969 May 20 at UT 19:35-20:30 Gomez (Spain, 12" reflector) observed
blue-white pulsating light in Aristarchus that illuminated the inner
walls - it was maximum at 19:55UT. This observation was made during the
Apollo 10 watch. The Cameron 1978 catalog ID=1128 and weight=5. The
ALPO/BAA weight=2.
In 1865 Jan 01 at UT 18:00-18:30? Grover (England? or USA?, seeing =
good and transparency = clear) observed south east of Plato at the foot
of Mt Blanc a small bright spot like a magnitude 4 star - slightly out
of focus. This bright speck remained unchanged for 30 minutes. The
Cameron 1978 catalog ID=137 and the weight=3. The ALPO/BAA weight=2.
On 1988 Apr 21 at UT 01:28-04:00 D. Fryback (Madison, WI, USA) took a
series of photographs - Aristarchus was a luminous patch and in one
photograph a red spot (Cameron suspects marks on the film). is seen
near Aristarchus. Strangely though when looking through the telescope,
the crater was not excessively bright. D. Spain (Fairdale, KY, USA,
3.5" reflector?, x60) observed a narrow white streak of mag 5-6 of
duration 0.5 sec that covered 160-320km near the centre of the Moon at
01:53UT. A similar streak happened but the direction was different.
Next 2 small red flashes were seen at 02:00 and 02:01UT of magnitude 7
(<1sec) in the vicinity of Aristarchus. The cameron 2006 catalog ID=327
and the weight=1.
On 1847 Dec 11 at 18:00UT Hdgson (Eversley, UK, x80 refractor and 40x
reflector) observed in Plato (Though it might have been Cape Agassiz or
Teneriffe Mts) a bright spot of about a 1/4 the angular diameter of
Saturn that varied intermittently and was at all times visible on the
night side of the Moon. The following day he glimpsed the same spot
rhough clouds. From his drawing the spot was ~5' below the true N.
point & near the following limb (IAU E. limb) Cameron comments that
Plato fits the angular distance better than the other two candidates
unless there was a large northern libration. The Cameron 1978 catalog
ID=125 and weight=3. The ALPO/BAA weight=3.
On 1969 May 20 at UT 21:00-22:00 Bury (France, 4" refractor) observed

On 1975 Mar 18 at UT 00:57-04:00 Reiland, Brown and Lojeck (Pittsburgh,
Pennsylvania, 6" reflector x45 and 8" reflector x200, photos taken)
observed the following at Aristarchus: "While obs. Earthshine on moon,
saw it glowing -- a bright steady star-like glow, est. at 5-8th mag.
First noted at 0057h. Obs. other obj. then came back to it. It was
still there -- till moonset (@0500h). Saw it in other telscopes &

weight=5. The ALPO/BAA weight=2.
On 1969 May 21 at UT 20:00-21:00 Brandli and Germann (Switzerland, 6"
refractor) observed a slow orange-red blinking on the surrounding area
of Aristarchus. It was seen less markedly the next night. Wald (Zurich,
Switzerland) noted at 20:30UT that the crater was pink (Confirmation
says Cameron) - this was during the Apollo 10 watch. The cameron 1978
catalog ID=1131-1132 and weight=5. The ALPO/BAA weight=4.
Fracastorius 1973 Mar 09 UT ~19:57 Robinson (Devon, UK) saw a

suspected of giving permanent blinks due to natural colour. The
ALPO/BAA weight=1.
On 1969 Jul 19 at UT 1845-18:47 Pruss and Witte (Bochum, Germany, 6"
refractor x36 and binoculars) saw brightenings in the north west wall
of Aristarchus for 3-7 seconds of about 1 magnitude over the
background. From orbit at UT 18:46 the Apollo 11 crew Armstrong,
Aldrin, and Collins (in orbit around the Moon and using the naked eye)
were asked to take a look at Aristarchus after Earth-based reports of
TLP activity. Armstrong reported (after the solar corona had set, on
the night side) that probably Aristarchus "to be considerably more
illuminated than the surrounding area. It just has - seem to have, a
slight amount of flourescence to it". Collins reported a moment later:
"Looking out on the same area now. Well at least there is one wall of
the crater that seems to be more illuminated than the others. I am not
sure that I am actually identifying any phosporesecence, but that
definitely is lighter than anything else in the neighborhood". Houston
then asked if the crew could detect any colour and if the inner wall
was the inner or outer part? Aldrim commnted that it was the inner
wall and Collins mentioned thatno colour was incolved. The Cameron 1978
catalog ID=1165 and weight=5. The ALPO/BAA weight=3.
On 1969 Jul 19 at UT 19:30-21:30 Gervais (Lodure, France, 4.5"
refractor?) saw the whole region of Aristarchus and its environs
as brighter than normal. Two photographs were obtained. The
Cameron 1978 catalog ID=1156 and weight=5. At UT 20:30-20:55
Oliver (Spain, using a reflector) found the Aristarchus to have
brightened by about 1 magnitude. From UT 20:12-20:30 the crater
had been normal. The Cameron 1978 catalog ID=1167 and the
weight=2. At UT 21:00-00:35 P. Mourilhe Silva (Rio de Janeiro,
Brazil, 19.5" refractor) saw Aristarchus as a very bright
elliptical shape which extended to the north like a bridge
between two points. Jose M. L. da Silva and Ronaldo Mourao (Rio
de Janeiro, Brazil, 13" refractor) saw a brightening on the
north west wall from 21:24-23:22UT intermittently but cont'd.
Wall was extraordinarilly bright, along NW wall brighter.
Moseley (Armagh, Northern Ireland, UK, 10" refractor) detected
an unusual bright, along north west wall, brighter than normal
in Earthshine and brighter than crater. It was not constant, but
pulsated irregularly with frequency of 20 seconds and amplitude
0.75-1.0 magnitudes. No colour seen or obscuration though lokked
for. Clouds interrupted observations. Vasquez (Valparaiso,
Chile, 12" reflector) saw it as a very luminous point of
magnitude 1. Wairy Cardoso (Rio de Janeiro, Brazil, 12"
reflector and 18" refractor) noted a bright. 1s??? The Cameron

Theophilus 1969 Jul 19 UT 19:30-21:30 Observed by Fox (Notts.
England, 6.5" reflector) and Ringsdore (England, 15"
reflector). Fox saw intermittent glow in Theoph. for > 2h
(time not given). Ringsdore confirmed. (Apollo 11 watch)"
Confirmed by Baum 21:00-21:20UT. NASA catalog weight=5. NASA
catalog ID No. 1166. ALPO/BAA weight=4.
On 1966 Sep 20 at UT 03:22 Three Astronet observers (Phoenix, AZ, and
Los Angeles, CA, USA) (independently?) reported flashes in Grimaldi
crater. One observer was in Phoenix AZ, and another in Losa Angeles,
CA, so probably not due to the atmosphere. Cameron comments that the
astronaut Schmidt on Apollo 17 saw a flash in it while orbiting the
Moon. the Cameron 1978 catalog ID=977 and the weight=5. The ALPO/BAA
weight=4.
South Pole 2011 Apr 08 UT 19:30-20:00 A.Kemp (Mold, Flintshire, UK) observed that the
Leibnitz peaks at the southern pole stood out sharply. However one of the peaks was “shining
like a spot light. So bright that I couldn’t make out its shape”. – image clear and steady with
excellent transparency and seeing in the 70mm f/13 refractor (25mm and 10mm eyepieces).
Inspections during the above time period revealed no changes in brightness. Previous
observations of this area had never shown such an unusual brightness, and Arthur likened the
brightness to “a maximum brightness of Venus shining amongst 2nd magnitude stars”. The
observer was an experienced observer. ALPO/BAA weight=2.
Mare Crisium 1826 Apr 12 UT 20:00 Observed by Emmett (England?) "Black
moving haze or cloud". NASA catalog weight=2 (low). NASA catalog ID
109. ALPO/BAA weight=1.
Grimaldi 1969 Jul 19 UT 20:39-20:45 Delaye (France, 25cm
refractor) saw a bright bluish spot near Grimaldi. 20:43 a
flash was seen by Thinon. Delaye saw flashes at 20:44 and
20:45. Between 21:00 and 23:00 (J. M. L.) da Silva (Rio de
Janeiro, Brazil, 19.5" refractor) saw a bright spot on the W
(IAU??) of Grimaldi. However there is a bright spot near
Grimaldi, so this maybe normal. NASA ID = 1167. The ALPO/BAA
weight=2.
On 1990 Mar 31 at UT 21:30 L. Jackson (England, UK?) observed a red
glow in Earthshine in Gassendi as shown in a sketch. Apparently
Gassendi can often show up red colours (according to Cameron) but
rarely is this seen in Earthshine. Foley saw the sketch and suspects
that the location was Gassendi. The Cameron 1978 catalog ID=397 and
weight=2. The ALPO/BAA weight=3.
On 1984 Jul 04 UT 22:08-23:09 Foley (12" reflector, Kent, UK) found
that Censorinus gave a low brightness CED reading of 58%, despite all
other measured points on the Moon as being normal. M. Cook (Frimley,
UK) found Censorinus to be extremely dull compared to Proclus. J.D.
Cook (Frimley, UK) found Censorinus to be quite dull, barely above
background levels. The Cameron 2006 catalog ID=246 and the weight=4.
The ALPO/BAA weight=3.
On 1984 Jul 04 at UT 22:05-23:09 Richardson (Swinton, Yorkshire, UK,
seeing=VE) found that a peak west of Theophilus crater had a deep blue
colour, and this was strange because no colour was seen elsewhere on
the Moon. Foley (Kent, UK, 12" reflector), once alerted, found a dome
east of Kant? to be blue, and likewise no colour was seen elsewhere on
the Moon. Cameron 2006 catalog ID=246 and the weight=4. The ALPO/BAA
weight=3.
On 1984 Jul 04 UT 22:08-23:09 Foley (12" reflector, Kent, UK) found
that Torricelli B was a much lower brightness than was expected and
this remained the case for the rest of the lunation. The Cameron 2006
catalog ID=246 and the weight=4. The ALPO/BAA weight=1.

NASA catalog weight=1 (very low). NASA catalog ID #1174.
On 1969 May22 at UT2045-2105 Wald (Zurich, Switzerland) observed the
pinkish colour in Aristarchus was less marked tonight. The astronauts
were alerted and at 22:12 reported no activity but could see the crater
and Earthshine was strong near the terminator. Apollo 10 watch,
spacecraft far from the terminator. The Cameron 1978 catalog ID=1134
and the weight=2. The ALPO/BAA weight=2.
On 1984 Jul 05 at UT 00:00-01:25 Marshall (Medelin, Columbia,
seeing=II) observed that Censorinus was much less bright than Proclus
(confirmed by CED readings). Cameron 2006 catalog ID=247 and weight=3.
ALPO/BAA weight=1.
On 1984 Jul 05 at UT 00:00-01:25 Marshall (Medelin, Columbia) found
Proclus to be much brighter than Censorinus (which of the two was
abnormal is a question) - though he thought that Censorinus looked
dull. The Cameron 2006 catalog ID=247 and weight=3. The ALPO/BAA
weight=1.
Atlas 1969 May 22 UT 21:20-21:40 Observed by Germann, Wild, Vieli
(Zurich, Switzerland, 6" reflector) "Rim towards the sun was bright.
Part of time was interrupted. (Apollo 10 watch)" NASA catalog weight=3

On 1969 Jul 20 at UT 19:55-20:10 Delaye, Thinon, Donas, and Jourdran
(Marseilles, France, 10" refractor, x60) saw between 19:55-20:04UT
Aristarchus to be bright and in it pulsations with 10 sec duration. At
20:05UT it's spot brightened, at 20:08:50-20:35:50UT brightening and
pulsations of variable duration. At 20:55:50UT just a feeble flash.
Cameron comments that this is probably not atmpsheric effects as the
period is too long - also it was during the Apollo 11 watch. The
Cameron 1978 catalog ID=1175 and th weight=3. The ALPO/BAA weight=3.
Mare Crisium 1826 Apr 13 UT 20:00 Observed by Emmett (England?) "Black

Knopp of Paysandu, Uruguay on 1885 Feb 21 at 23:00-23:30? UT saw red
patches in the crater. Reddish smoke or mist. The observer says several
others had seen a star like point there that night. Cameron's 1978

Censorinus 1984 Jul 05 UT 21:05-21:25 Observed by Cook (24" reflector
with line scan photodiode array at Mill Hill observatory, London) "Two
line scan photodiode array images were taken which used the motion of
the Moon to build up an image. The first image at 21:25UT did not
include all of Censorinus, but the part that it did include was not
very bright. The 21:25UT image did include all of Censorinus and the
crater was bright, including the part that was just visible in the
previous image. Possibly the seeing was worse at 21:05? and this could
explain the brightness descrepency, but it is worth checking again by
taking images at the same illumination conditions" BAA Lunar Section
report. At 21:17 M. Cook (Frimley, UK) found Proclus to be brighter
than Censorinus (more so than the previous night) and obtained variable
readings for Censorinus. Cameron 2006 catalog ID=247 and weight=3.
ALPO/BAA weight=2.
Mons Piton 2022 Aug 04 UT 19:41-20:10 T. Smith (Codnor, UK,
16inch Newtonian, x247, Seeing IV) mountain was very bright
and red around its eastern slopes. An examination of the
bright and contrasty Proclus crater revealed that to be
relatively colour free compared to Piton. An examination of
other features, north and south along the terminator revealed
some tinge of coloiur but not as strong as on Mon Piton. Mons
Piton examined with a yellow filter at 19:50 and still showed
red along the eastern side, other features along the
terminator had no colour through the filter. Video images by.
A.Cook (Newtown, UK) made earlier at 1929 & 19:40 UT, (in the
SWIR (1.5-1.7 microns) did not reveal Mons Pico as especially
bright - but resolutioin was poor. A friend of Smith, phoned
up the next day to say that they saw a mountain on the limb
exhibiting red on the 14th August. Probably the redness was
due to atmospheric spectral dispersion as the Moon was low,
and it was especially visble on Mons Piton as this is an
exceedingly contrasty object on the terminator. ALPO/BAA
weight=1.
Theophilus 1969 Jul 21 UT 19:30-21:45 and 21:00-22:00 Observed by Fox
(Newark, England, 6.5" reflector,) and Baum (Chester, England, 4.5"
refractor) (S=6, T=4) "At wall, adjacent to Cyrillus was a redish glow,
then obscur. (Fox). Baum saw intermittant white-blue shimmering as if
glowing thru dust glowing & upsurge in brightness on c.p. Gradually
faded to normal at 21:20. 1st time ever seen by him tho. obs. since

On 1991 May 21 at UT05:30-06:15 J. Green (Orangevale, CA, USA, 11"
reflector) photgrapphed a broad bright band stretching east and north
of Cassini crater in 3 exposures taken 10 minutes apart. This
photographic sequence shows a gradual widening towards Cassini and by
the 3rd exposure the band is touching (and then obscuring) Cassini. A
"fan" was visible in the north east and WSW directions, later this was
seen as rays and this was even seen in the view finder of the camera.
Cameron comments that this might be lens flare but suspects that it
would not have been seen in the view finder. The Cameron 2006 catalog
ID=427 and the weight=5. The ALPO/BAA weight=2.
Hyginius Cleft 1966 Jul 25 UT 04:40 observed by Kelsey (Riverside, CA,

Bessel - could be a photographic defect?. ALPO/BAA weight=1.
Messier 1968 May 05 UT 01:35-03:35 Observed by Delano (USA).
No oclour noticed with Moon blink device, but Messier A's W.

compared to Messier's W wall. The ffect was less marked in
the 2nd hour. ALPO/BAA weight=1.
Plato 1882 Mar 27 UTC 20:10-21:00 Observer: A.S. Williams (Brighton,
UK, 5.5" saw the shadow filled floor of Plato at Sunrise with a
"Glowing and curious milky kind of light". About 1 hour after sunrise
at Plato, there was no trace of this effect. The TLP filled the whole
floor except at a quarter of the diameter from the east wall which was
actually quite black. The observer saw a curious phosphorescent glimmer
at sunset (April11th?). Cameron comments that Birt, Nelson and Waugh
saw obsecuring mist or fog in Plato on many occasions. Cameron 1978
catalog ID=229 and weight=3. ALPO/BAA weight=3.
Knopp of Paysandu, Uruguay on 1885 Feb 22 at 23:00-23:30? UT saw a

College, Whittier, CA, USA, using a 10" f/8.2 Newtonian
reflector, x78 & x208, seeing 5-6, transparency 2-0) observed a
ridge obscured SSW of Ross D. No drawing was made, only a
written description. "Ridge not visible near crater; possible
white patch 1/3 Ross D diameter" The ridge is the wrinkle ridge
extending NNE from Ross D, a well established often visible
feature. Harris comments that this was not one of the better TLPs
seen near Ross D, and there were no independent observers,
neverless he was ceratin of this being a TLP, and it was
consistant with other activity seen near this crater between 1964
and 1970. Cameron 1978 catalog ID 891 and weight=3. ALPO/BAA

Theophilus 1978 Nov 08 UT 20:49-22:00 Observed by J.D. Cook
(Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV)
Orange discolouration seen on ESE crater floor. Moon blink
tried, but no blink detected. By 21:10 the effect had lessened,
but was still orange. By 21:50-21:58 the effect was smaller and
perhaps more on the SE of the floor. Colour confirmed by Foley.
Fitton may also have been observing. At 22:00 A.C. Cook observed
and commented that a darkish, perhaps brown-orange colour seen -
but suspected it was probably spurious colour - but by now the
seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of
several features, including Theophilus, had not noticed anything
unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect
a blink, but noticed intermittent darkining on the shaded area
on the E. floor, but seeing was now IV. The darkening was more
noticeable in blue than red light. BAA Lunar Section
observation. 2006 Cameron catalog ID #40 weight=3. ALPO/BAA

On 1972 Feb 23 at UT0010-0035 Fornarucci (Garfield, NJ, USA, 6"
reflector, x250, seeing=fair and transparency=3.5). Shading
usually visible west of it was not seen. Cameon comments that
the albedo must have been at 5, where normally it is 4.5 and the
nearby plain is 5). Cameron 1978 catalog ID=1322 and weight=2.

On 2009 May 03/10 UT23:20-00:11 P. Abel (Leicester, UK, 20cm reflector,
x312, seeing III-IV) observed that the north east wall was slightly
brighter than would have been expected, slightly blurred (not seeing
related blurring) and had a strong orange-brown colour. No spurious
colour seen elsewhere. A change in eyepieces showed the same effect. No
luck in alerting other observers. A drawing was made at 23:20UT and
finished at 00:12UT. At 23:12UT part of the inner NW floor had a dull
brown colour, whereas before it was grey.By 00:11UT the colour effect
was fading and by 00:18 seeing condirions were too bad to continue. M.
Cook (Mundesley, UK, 9cm Questar telescope, x80, x130, seeing III,
transparency moderate to good) had observed Tycho earlier in the
evening at 22:15UT, but had seen no signs of colour. W. Leatherbarrow
(Sheffield, UK, 8cm scope, high cloud interuptions and bad seeing) had
taken monochrome images at UT 20:07 and 20:10, but these showed nothing
unusual, and he checked the crater visually at 00:00-00:30, but
detected no colour, although the Moon's low altitude contibuted to poor
seeing conditions and some spurious colour was seen. CCD images from M.
Collins (Palmerston North, New Zealand) taken at 00:46UT showed
nocolour apart from spurious colour on contrasty edges, in no way
reflecting what was seen early by P. Abel. The ALPO/BAA weight=2.
Observer made a drawing over a period of 30 minutes. Upon
examining drawing, and comparing with photos made under
similar illumination was struck by the abnormality of a
a small white blob in the north east corner of the shadowed
floor. There should be no raised topography between the wall
and the central peaks that could give rise to this. The making
of the sketch overlapped with an earlier drawing made by Rony
de Laet (Belgium) which did not show this blob. Subsequent attempts
to find sketches/images at very similar illumination angles have
failed to show the blob in the north east corner of the chadowed
floor. ALPO/BAA weight=3.
Birt 1955 Apr 15 UT 03:20-05:00 Observed by Capen (California
Seeing=Excellent) "Small craters between Birt & wall were invis. at
times under excellent seeing, while craterlets on w.side were
continually obs." NASA catalog weight=4 (high). NASA catalog ID #586.
On 1990 Apr 04 at UT 21:30-21:50 B. LeFranc (France?) reported
observing a white flame effect in Copernicus crater (sketch made) -
though Foley comments that the actual location was east of the crater.

Plato 1969 May 26 UT 20:30-21:05 Observed by Farrant
(Cambridge, England, 8" reflector, x160, S=G) "Had misty
portion of SW(ast. ?) floor from 2030-2105h at which time it

Proclus 1989 Jul 13 UT 21:04-21:13 Observed by M.Cook (Frimley, UK,
90mm Quastar Cat., Seeing III, transoparency hazy) and by Moore
(Selsey, England) "Following an alert call by Miles concerning the
crater Proclus looking different, Cook observed a circular dark patch
that filled about half of the eastern half of the crater floor. To cut
down the glare a blue filter was then used and a slightly less dark
area was seen extending from this in a southerly direction. 8 rays were
seen. The dark patch was confirmed by Patrick Moore. However David
Darling (USA) who observed a few hours later on 1989 Jul 14 at 03:28 UT
could not see this dark patch." BAA Lunar Section observation. The

(very low).
Interior bands were faint at 22:40 but sharper at 23:20.
Observer noted some blue spurious colour to the north of
Aristarchus but this had gone by 23:50.
Observer noted some variability in the brightness of Moltke
and Torricelli B. This observation has an ALPO/BAA weight of 3.

On 1988 May 18 at UT01:00-02:35 Lubke (Middleton, WI, USA, 8"
reflector, x130) reported that Aristarchus glowed "like an out of focus
star varying with the atmosphere". Darling (Sun Praire, WI, USA, 20x60
binoucular) and Spain (Fairdale, KY, USA, 7x35 and 20x60 binoculars, S=
6/10) found that both Copernicus and kepler were brighter than
Aristarchus in Earthshine. Aristarchus itself looked unusual, though
Spain did not see Aristarchus at all. Darling and Wieir (20x60
binouculars) agreed that it appeared as a star-like point in
binoculars. Cameron 2006 catalog ID=326 and weight=0. ALPO/BAA
