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.
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.
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.

give date as just 1895 but must be wrong-phase - see app.ref.)"
NASA catalog weight=4 and catalog ID #304. ALPO/BAA weight=2.
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 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.
Stochard of Dublin, Ireland, saw naked eye at 10:30UT on
1862 Nov 12 Aristarchus as extraordinarily bright as a bright
spot on the Moon. This was seen in daylight with the waning
crescent. Cameron 2006 extension catalog ID=6 and weight=3.

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.
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 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
ALPO/BAA weight=1.
On 1991 Dec 09 at UT 22:50 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 ALPO/BAA weight=2.
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
ALPO/BAA weight=2.
On 2010 Dec 09 at UT 17:00 A. Heath (Long Eaton, UK) whilst
observing the Earthsine with 10x50 binoucluars, noticed some
coloured bands on the night side. The NW sector of Eartshine,
closest the limb was a normal dull brown, there was a whitish
fringe on this going from the N to the SE, followed by a thicker
bluish fringe. The rest of the Earthshine beyond, until reaching
the illuminated crescent was black. The two coloured fringes
curved slightly. Local temperature 38F and some broken cloud
present. Thickening cloud prevented further observations. The
observer suspects that it could have been caused by the weather
conditions, but could also have been due to a cataract starting
to form in his observing eye. This is unlikely to be a TLP due
to the above observer suggested reasons, and anyway it would
have to have been an unbelievably large phenomena to cover such
a large part of the Moon. However it is worth checking to see if
anybody else was observing at the time. ALPO/BAA weight=0.
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.
North shore of Mare Crisium 1915 Dec 11 UT 06:00? Observed by
Thomas (Glenorchy, Tasmania) "star-like pt. on N. shore of
mare. (Eimmart?) Particularly bright spot. Tho't it was
sunlight from rim of sm. crater." NASA catalog weight=0 NASA
catalog ID #358. 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.
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 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 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 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.
Proclus 1983 Jan 19 UT 20:36-21:00 Observed by Cook (Frimley, UK,
Seeing III, Transparency, Moderate) "Colouration seen". BAA Lunar
Section Report. ALPO/BAA weight=2.
Leibnitz Mountains 1948 Apr 14 UT 20:00? Observed by Wilkins
(Kent, England, 12.5" reflector) " S.cusp prolonged -- detached
peaks -- starlike pts. connected by fine filaments brighter than
earthshine. (Barcroft, Haas, Vaughan, Moore & Firsoff also have
seen similar phenom.)(just sunlight catching high peaks?)." NASA
catalog weight=2. NASA catalog ID #502. ALPO/BAA weight=1.
On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP
coordinator, Patrick Moore, to report a possible colour anomaly in
Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing
unusual. However by this time North was reporting that, the colour was
fading. Two other BAA members were alerted, but were clouded out. The
ALPO/BAA weight=3.
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.
Webb (England, using a fluid achromat) saw brilliant minute spots and
streaks in Mare Crisium dotting its surface. This was seen near first
quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall
had all seen it this way at times. Cameron 1978 catalog iD=111 and
weight=3. ALPO/BAA weight=2.
Plato 1948 Apr 15 UT 20:00? Observed by Thorton (Northwitch, England,
9" reflector) "Brilliant orange-yellow flash 1 km inside E. rim
(similar to earlier #500 LTP flash in the dark)" NASA catalog weight=3
(average). NASA catalog ID #504.
Aristarchus appeared to glow in Earthshine with a faint
green luminescence that moved from side to side. A bright
blue central spot was also seen. The green colour was detected
in two seperate eyepieces. Observation made from England.

ALPO/BAA weight=2.
On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a
10" reflector at 32-64x) noticed that Aristarchus was not
visible, although the Earthshine was very obvious. Foley (of
Kent, UK, and using 12" reflector) noticed that the crater was
only just visible but Plato could definitely be seen. Cameron's
2006 TLP extension catalog ID=125 and weight=0. ALPO/BAA
weight=2.
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 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

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).
Alphonsus 1972 Sep 15 UTC 18:48-18:56 Observed by Hopp (13.25E, 52.5N,
75mm refractor) "Diffuse white to blue area within the crater - not
sure" T=4, S=4. Ref: Hilbrecht & Kuveler Moon & Planets (1984) Vol 30,
pp53-61.
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.
Pickering 1971 Jan 04 UTC 20:29-20:37 Observed by Collier (London,
England) "Between Saunder and Rhaeticus, apparently coming from Pick.
After 2027h it dimished with extraordinary swiftness, like a light goes
out. (experienced observer)" NASA catalog weight=?. NASA catalog ID #
1281. Note that this crater was previously called E.C. Pickering before
the IAU renamed some craters.
2004 Nov 20 UT 01:43:36 R. Spellman (120mm F8.3 refractor at
prime focus, PC23C CCTV camera, via a DVD recorder) recorded
a flash of light. The ALPO/BAA weight=1.
On 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.
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."
1996 Apr 27 UTC 02:26-03:14 Observed by Spellman (Los Angeles, CA, USA)
" 02:26 U.T. Sunrise on Tycho 3/4 of the crater was in shadow,
topmost section of the central peak was in sunlight. In white light
brightness of the central peak rivaled the brightness of the Eastern
(sunlit) wall. No change was detected in red light, however in blue
light definite strong darkening was observed. Blink obtained when
viewing thru 25A and 38 filters. At 2:52 U.T. in the poor to fair
seeing the apparent size of the central peak in white and red light was
the same, in blue light the central peak in white and red light was the
same, in blue light the central peak size shrank to 1/2 white and red
size (and brightness). Also appearing sharper. Comparison was made also
with the central peak of Alphonsus, no changes were observed. The
significant part of the observation was the relative brightness of the
central peak to the sunlit rim in white and red light, they appeared
almost identical with the crater rim, being just slightly brighter. In
blue light the brightness of the central peak was reduced by at least
half while the rim brightness was not, (relative to one another). I
strongly believe that this was a real event. The shadow filled
portion of Tycho was examined for any abnormalities but none
were observed. Observations were ended shortly after 3:14 U.T. due to
clouds. I also conducted about 20 Moon blink observations during this
observing run and got the same strong reaction each time." ALPO/BAA
weight=3.
On 1936 Oct 25 at 01:35 UT W. Haas (Alliance, OH, USA, 12"
reflector) saw small bright spots on the floor of Eratosthenes,
(Pickering's atlas 9A, col. 30deg, shows no spots - according to
Cameron). Cameron 1978 catalog TLP=417 and weight=4. ALPO/BAA

Cichus 1975 Sep 15 UT 11:15-11:30 G.Ryder (Corinda, Australia,
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
were starting to become visible as time went on, but it had
clouded over by 11:30. A Moon Blink was used but no colour was
detected. ALPO/BAA weight=1.
2004 Jan 02 UT 09:05 (approx) M. Collins (Palmeston North, New
Zealand, ETX 90, seeing 3, clear) saw a possible(?) flash north
of Carlini D at about 16W, 35N in adverted vision. It lasted
only a split second. The ALPO/BAA weight=1.
A region of the Mare Imbrium was extremely bright, giving
a reading of 8 out of 10 on the Elger scale. Cameron notes
that from photos of the Full Moon, the area appears to
normally be the brightness of Archimedes floor i.e. 3.5 out
of 10 on the Elger scale. Atmospheric seeing was excellent
and the observer could see a lot of fine detail with their
2.4" and 3" refractors. Cameron 2006 catalog extension ID=62
and weight=3.
Sinus Iridum 1996 Apr 28 UT 20:00 Observed by Brook (Plymouth,

Bulialdus 1979 Aug 03 UT 21:36-21:48 Observed by Cook (Frimley, UK,
seeing III, Moonblink device) "Bullialdus eastern side of the crater
looked brighter in red i.e. rim and exterior, extending to the south
slightly and this reddish areas was slightly hazy. At 21:41 it clouded
over but at 21:47-21:48 it cleared briefly and effect was noted again.
Also Darney appeared very visible through the red filter. Probably
spurious colour as the Moon was -18 deg in declination and the whole
Moon had a slight brownish tinge" ALPO/BAA weight=1.
Darney observed by Cook (Frimley, UK, seeing III, Moonblink device)
See TLP report for Bullialdus (eastern side) concerning reddish
areas. At 21:41 it clouded over but at 21:47-21:48 it
cleared briefly and the effect was noted on Bulialdus again.
Also Darney appeared very visible through the red filter.
Probably both effects were spurious colour related as the Moon
was -18 deg in declination and the whole Moon had a slight
brownish tinge. An ALPO/BAA weight of 1 is assigned to this TLP."
In 1820 Oct 17 at UT 20:00 an unkown observer reported in Mare Imbrium,

Gassendi 1977 May 28/29 UT 20:45-21:15 Observed by D. Sims
(Dawlish, Devon, UK) saw a hazy area on the south east floor
that was normal in red and white light but darker in blue.
This was partly confirmed by J-H Robinson (Devon, England, 10"
reflector) 21:24-23:12 who saw the south east floor of
Gassendi to have a loss of detail - but no colour seen,
although at 21:57-21:58 it was slightly brighter in red than
in blue briefly. P. Doherty (22:45-23:15) did not see anything
ususual. D. Jewitt (22:22-22:55) did not reveal anything
ususual, apart from spurious colour. The Cameron 1978 catalog
ID=3 and ID=1463. The ALPO/BAA weight=3.
On 1990 Sep 30 at D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x150) observed a red spot on the west wall (bright
in red filter and faint in the blue filter. No filter
reactions were found elsewhere. Gassendi had much detail

Plato 1982 Jun 02 UT 22:00. Mobberley could not see the
central craterlet on the floor of Plato tonight. Foley notes
that he could only just see the central craterlet on nights of
2-5th Jun and it was of reduced in brightness from normal.
North reported that the floor seemed nearly black, but
brighter in a green filter (x144 magnification used). All
three observers compared the Plato area to other areas for
reference. All the above seems normal, apart from the floor
being brighter in the green filter. Cameron 2006 extension

On 1989 Sep 12 at UT00:58-02:25 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x159, S=7/10) observed similar light conditions to 1989 Jul
15. At 02:00 he observed pink on the south west wall of Aristarchus
crater. At 01:24UT the Aristarchus ray was yellowish, however the
entire Moon had a grey-yellow tinge of colour. Chromatic aberation was
observed at 01:56UT. By comparison Gassendi was checked and had no
colour. At 02:10 the crater wall of Aristarchus was unusual and was
quite different in appearance to rims of other craters. The cameron
2006 catalog ID=375 and the weight=1. The ALPO/BAA weight=1.
G. Ward (a lunar observer for 15 years) observed an area just south
west of Mersenius C to be blurred and in a greenish cloud. The green
colour was more like that of dead grass than one gets from a neon bulb.
The effect was seen from 04:50-04:57UT, but could have been going on
before it was first noted at 04:50-UT. Seeing was 6-7/10 4" Refractor
(2 element). refractor had been used hundreds of hours before (over a
10 year period) with no similar colour was seen. The observer checked
other areas but did not see any similar effects. They also rotated and
changed eyepieces, but this made no difference to the TLP. The TLP site
seen was picked up on an image taken earlier at 04:47UT by W. Bailley,
from Sewell, NJ, USA. Unfortunately the area concerned, a mountain on
the image, was saturated and so we cannot tell if a colour was present
there and the seeing was poor.
Aristarchus 1975 Oct 16 UT 20:00? Observed by Foley (Kent,

Cobra Head 1949 Feb 10 UT 00:00? Observed by Thorton (Northwich,
England, 18" reflector) "I was examining the Cobra Head of the Schroter
Valley, when I noticed what seemed to be a diffuseed patch of thin
smoke or vapour, apparently originating from the valley on the E. Side
where the landslip is, and spread over the edge on to the plain for a
short distance. Every detail of the edge of the valley was perfectly
clear and distinct except where this patch occurred, but there the
definition was poor and very blurred" NASA catalog

observed that Gassendi still had a blink effect when viewed through
blue (Wratten 38A) and red (Wratten 25A) filters. No effect was seen on
Aristarchus. Gassendi was brighter in the red filter and this was
confirmed by Weier. Sketches were made and brightness measurements
taken. Both observers used a 12.5" reflector x159. At 01:00UT the NW
wall was 7.5, the SW wall 8.0, the S. wall 7.5, the floor 6.0, the

Deslandre - 1965 May 12 at UT 19:10 E. Penzel
(Rodewisch, East Germany) was taking a sequence of images
during the impact of the Soviet Lunik 5 (upper stage of the
carier rocket?). He detected a tens of km scale elongated
cloud after the impact over a duration of 9.5 minutes. This
was near to Deslandre crater. However there are differences
between the images elsewhere on the Moon, possibly due to
different exposures or some other effects and it is not 100%
sure that what he detected was impact debris/cloud?. The

Aristarchus Area 2004 Nov 22 UT 04:58-05:49 Observed by Gray
(Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5,
x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red
25. The illuminated west crater wall stood out brilliantly in blue
light, much more so than in white light. This was true also of
Aristarchus. Red light did not increase contrasts in Herodotus any more
than they were in white light. Shadows in Herodotus appeared as black
as the night west of the terminator and remained that way throughout
the observing period. No TLP seen in Herodotus tonight. A possible TLP
was seen to the west of Herodotus near the terminus of Schroters
Valley. It was noted at the beginning of the observing period that
there were four very bright spots of light, one near the end of
Schroters Valley, the other three grouped together a little farther
north. Although not far from the terminator they were definitely east
of it. It was noted that all of them nearly vanished in the Blue 38A
filter while Aristarchus and the rim of Herodotus gleamed brilliantly.
At 5:19UT it was noted that the most brilliant of the four lights, the
one near the terminus of Schroters Valley, had faded almost to
invisibility in white light. When first seen it had been brighter than
Aristarchus. It remained very dim after this through the remainder of
the observing period, and was unchanged at 7:35-7:49UT when I again
examined the area. The other three bright spots remained brilliant and
unchanged."
D. Darling of (Sun Praire, WI, USA, using a 12.5" reflector at x150,

On 1984 Feb 14 P. Moore (Selsey, UK) thought that there was something
odd about Mons Pico in that it looked very bright and gave a good
impression of a crater. Cameron 2006 catalog extension ID=241 and
weight=5. ALPO/BAA weight=2.
On 1984 Feb 14 P. Moore (Selsey, UK) observed that Plato was darker
than the nearby mare and no detail could be seen on the floor or the
eastern wall - the later was obscured. At 23:40UT some dimming was
still present on the north east wall and still no detail on the floor
of Plato. Cook noticed that the eastern floor close to the wall was
misty and also noted no detail on the floor. Amery though noted that
all parts of the floor were sharp although some darkening was visible
in the north west and a hint of obscurtion. The east wall though was
quite sharp. Mosely could see the central craterlet but from 8-6
o'clock tricky to define (Foley says that this effect has been seen at
this colongitude before). Streak ray across the floor of Plato seen
(North) - filter measurements made. Cameron 2006 catalog extension ID=
241 and weight=5. ALPO/BAA weight=2.
Vallis Schroteri 1991 Aug 23 UT 02:19-02:49. Flashing spot at
end of SV fluctuated. Herzog, Darling & Weier confirmed spot
but not fluctuation. Spot brighter in red than blue, but Cobra
Head was bright in blue. No other region was abnormal.
Amery (Reading, England) saw blue in Aristarchus but a photograph did
not show the colour. Foley thinks this was spurious colour. Cameron

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

edges were nebulous even at best seeing. Size @ that of Cobra's Head."
NASA catalog weight=5 (very good). NASA catalog ID #1053.
Peter Foley (Kent, UK, 8" reflector, seeing=II) noticed that
the floor beneath the north wall, and the area over the north
wall were indistinct (almost out of focus). Despite looking
elsewhere in the crater and surrounds, no other blurring
(obscuration of detail) could be seen, indeed everywhere else
was sharp and detailed. Foley tried several eyepieces but this
made no difference. He used a crater extinction device but
found no variations in brightness. There was a slight
darkening when he used a red filter in the Moon Blink device.
The obscuration effect weakened between UT20:56 and 21:10,
was difficult to see at 21:13 and had finished by 00:15.
Patrick Moore (12" reflector, Dublin, Ireland) saw nothing
unusual when he started observing at UT 22:00. Cameron says

On 1982 Jun 05 at 22:00? UT, Chapman (UK, using a 12" reflector), again
using a x2 yellow filter, noticed that the central craterlet
detectabilty changed such that sometimes it was visible and sometimes
not. Foley (Kent, UK)noticed that the central craterlet could only just
be seen between June 2 to June 5 and was much less discernable than
during the previous lunation. No CED brightness measurements made. The

ID=172 and weight=4. ALPO/BAA weight=2.
F. Graham took some photos of the Cobras Head and found a blue cloud
about 50 km in diameter and scattering light - Cameron says that
this indicates high density. Darling found the Cobra's Head obscure and
variable "clear and bright to diffused". Cameron was alerted observed
(02:40UT) variations with periods of approximately 30 seconds, and
thought that she could see a red tinge on the east rim of Aristarchus -
checks elsewhere found no other colours. Darling found that a blue
filter enhanced the effect and a red filter made it disappear. There
was a blink at 02:55UT but no blink in the Cobra's Head, which looked
fuzzy and lacking in detail. The effect was confirmed by Weier, who
also saw two dark spots in the Cobra Head in blue but not in red light.
The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall
7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south
wall 7.0, East wall 8.0, and the central peak 10.0. Observer details

Lichtenberg 1951 Jan 22 18:19.2-18:38.5 UT observed by Baum
(Chester, England). Tiny red spot noticed initially and then
faded. Location of spot 31.403N 66.167W. 20cm refractor x90-

Gassendi 1966 Dec 27 UTC 06:30-07:05 Observed by Kelsey (Riverside, CA,
USA, 6" reflector?) "Very faint blink on SW (ast. ?) floor & on another
N. of it on NW floor. Obs. considers obs. very suspect" NASA catalog

On 1989 Oct 14 UT 19:00?, 22:00? P.W. Foley (Kent, U.K., using a 12"
reflector) noted that although the brightness of Aristarchus crater
seemed steady, that there was just too much detil to see inside the
crater than one would expect. Appeared as two craters - Cameron
commented that this was often seen by Bartlett. Several observers
apparently confirmed this TLP? Cameron 1978 catalog extension ID=379
and weight=5. ALPO/BAA weight=2.
Aristarchus 1954 Oct 12 UT 00:55-02:10 Observed by Bartlett

Aristarchus 1973 Feb 15 UTC 17:07-19:31 Observed by Theiss (located at
51N 5.67E) "area 4-5 diameters of Aristarchus were coloured clearly
yellow-red" 120mm reflector used. Ref Hilbrecht & Kuveler (1984) Moon
and Planets Vol 30 p53-61. ALPO/BAA weight=1.
Plato 1973 Aug 13 UT 22:25-22:35 observed by Pedler (Devon, UK).
Observer noticed a slight blink on a lighter patch on the floor
just beneath the south(?) rim using Moon blink filters.
ALPO/BAA weight=1.
David Darling observed bright glittering on Aristarchus. This
was followed by a flare up in brightness at 00:38:05 UT in the
comet-like ray area of the crater equivalent in intensity to the
central peak. Then he saw another one on the north east rim of
Aristarchus of the same brightness. A third flare was seen at
00:49UT in south of Herodotus, on the comet-like ray. Another
two flares were observed at 00:56UT on the north west rim of
Aristarchus. Darling suspects that these effects were due
to seeing effects and Cameron agrees. However Weier suspects
that they were TLP? Brightness measurements by Weier were for
the south west rim of Herodotus 8.0, for a spot at the Cobra's
Head 9.0 and 7.5 for C.H. Cameron apparently did not see the flashes
but did suspect that the interior of Aristarchus was a bit unusual.
Don Spain did not see anything unsual at all. Cameron 2006 extended
catalog ID=380 and the observation weight=3. The ALPO/BAA weight=2.
Aristarchus 1967 Dec 16 UTC 22:00? Observed by Farrant (Cambridge,
England, 8" reflector) "Crater took on an unusual appearance on inner
NE (ast. ?) wall. Showed a very pale blue & the opposite wall a pale
red color seen in no other features. Lasted only 10m & survived a
change of eyepieces." Seeing=I (Antoniadi). NASA catalof weight=3

Cobra Head 1955 Oct 31 UTC 19:00 Observed by Milligan (England?) "Dark
blue obscuration" NASA catalog weight=3 (average). NASA catalog ID 624.
On 1983 Jan 29/30 at UT20:35-01:00 Sykes (UK?) observed that
Linne appeared to brighten for approximately 20 min and had the
appearance of a point (confirmed). This observation was made
during a major Torricelli B TLP. The Cameron 2006 catalog ID=198
and the weight=5. The ALPO/BAA weight=2.
Torricelli B 1983 Jan 29/30 UTC 20:35-02:30 Observed by Foley (12"
reflector, seeing Antoniadi II, Transparency=good, no spurious colour
seen), Moberley (14" reflector, seeing Antoniadi II, transparency
excellent, spurious colour strong), Cook, J & M (12" reflector, seeing
Antoniadi II-III, transparency moderate). All observers based in
southern England. "Initially crater brightest feature on the Moon, then
it faded. Strong colour also seen by all observers e.g. green-blue to
violet. Report of observations written up in JBAA Vol 100, No. 3, p117
123, (2000) - probably one of the best reorted TLP". The Cameron 2006
catalog ID=198 and weight=5. The ALPO/BAA weight=5.
Mobberley noticed that Torricelli B was bright and had an even brighter
spot on the inner north wall. The observation was made from UT19:45-
21:40 using visual and video techniques. There was also a bright region
NNE of Toricelli B, that was noticed. Foley examined the video and
found that the crater faded in brightness over time and also the bright
area to the NNE was not as bright on video as had been seen visually.
Foley speculates that because the CCD camera was sesnitive to the near
IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and
also saw the bright spot on the inner north wall - but saw a blue halo
around the crater. Response in blue filter, darkening over whole
region. Brightness measures with a crater extinction device (CED)
indicated that the crater was 80-85% the brightness of Censorinus.
There was a bright area NNE of the region. M. Cook observed 22:10-
22:16UT (15cm reflector and seeing III-IV) and also saw that the crater
was very bright indeed with a spot NNE of the region (same position as
28/28 1985 observation) - suspected that the crater might have been
brighter than Censorinus, but judgement effected by seeing. In a blue
filter the crater dulled leaving the bright spot prominent (but only
during a good moment of seeing) - therefore had some suspicion of
seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the
area, but the seeing was even worse - but did manage a check of the
brightness of Torricelli B to Censorinus and now made it one quarter of
that of Censorinus and no sign of the crater dimming in the blue as had
been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at
21:15UT (Dec 27) thought that Torricelli B looked normal and saw no
colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images
through red+IR (Wratten 25) and IR (Wratten 87) but found no colour
differences, though there was a very slight hint that a brightness fade
may have occurred between those two observing times. Note that this
report does not have an entry in the Cameron 2006 Extension Catalog.
The ALPO/BAA weight=4.
On 1984 Feb 17 at 19:45-22:20UT P. Madej noticed colour in Aristarchus
and telephoned the BAA Lunar Secton TLP network. Mosely at 21:15UT
observed that Aristarchus was both bright and fuzzy - there was some
spurios color (red on south and blue on the north) but this was
replaced by violet. By 21:30UT (transparency=fair) the centre of the
crater was bluish and the west wall creamy white. the north and south
walls were brilliant white. By 22:00-22:30 UT the seeing had improved
and the crater looked unusual - now the centre was violet and the west
wall duller, off-white. By 05:35UT the crater was difficult to define
according to Cook - 4 bands could be seen under II seeing and the north
rim was fuzzy and less bright than the east wall (this was hazy). P.
Moore observed that the crater was normal at 04:00UT. Cameron 2006
catalog extension ID=242 and weight=3. ALPO/BAA weight=2.
On 1984 Feb 17 at 19:45-22:20UT P. Madej (England, seeing=III-
IV, x50)noticed that the crater Reinhold had a blood red spot
on the northern terraces, at the base of the inner wall in a
summit crater on the last of a crater chain or ridge
descending from the top to floor". Cameron 2006 catalog
extension ID=242 and weight=3. ALPO/BAA weight=3.
Aristarchus 1976 Aug 11 06:44 Observed by Bartlett (Baltimore, MD, USA,
4.5" reflector, 45-300x, S=4-3, T=4) "Pale viol. radiance (gas?) on
plateau m. Dark viol. tinge on nimbus. C.p.=10 deg walls=8deg, & all of
floor=8 deg. W.wall out of focus due to haziness (gas?)." NASA catalog
weight=4 (high). NASA catalog ID #1441.
On 1983 Jan 29 at UT22:09 M.Mobberley (Sulfolk, UK, 14" reflector)
noted that Arago B had a slight tinge of violet colour, and was a lot
less (bright?) than Torricelli B's blueness. Other craters checked but
were not showing any blue colour. The Cameron 2006 catalog ID=198 and
weight=5. The ALPO/BAA weight=3.
On 1983 Jan 29 at UT22:09 M. Mobberley (Suffolk, UK), found that Moltke
crater was "exceptionally bright". Other craters (apart from Arago B
Torricelli B etc) appeared normal. The Cameron 2006 catalog ID=198 and
the weight=5. The ALPO/BAA weight=2.
Proclus 1972 Nov 21 UT 21:30 Observed by Farrant (Cambridge, England,
8.5" reflector, x130) "Thickened bright ring remained, but the dark
patch had disappeared. (dark patch prob. real temporary phenom. as it
was seen nr. FM when contrasts are strongest, yet disappeared" NASA
catalog weight=1 (very low). NASA catalog ID #1351.
CCD images taken through Wratten 25 (red+near IR) and 87
(near IR only) filters. Between 00:02 and 00:25UT there
was some slight evidence that a fade may have taken place
however careful analysis by Cook casts doubt on this.
Probably it was more related to a degradation in image
quality due to seeing than a true TLP. An ALPO/BAA
weight of 1 has been assigned.
Aristarchus 1973 Oct 12 UTC 18:13-18:45 observed by Pasternak "Bright
region of the S. of the crater, color was red." - Hilbrecht and
Kuveler, Earth, Moon & Planets, 30 (1984), p53-61. ALPO/BAA weight=1.
On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50)
observed a bright flash (~0.3 sec duration) near to Copernicus (20W,
9N) with rays to the south east whilst he looked through a finder
scope. Moore, who studied the drawing, suggests that the area of the
flash was near Copernicus. However Cameron says this cannot be the case
if the flash was in darkness as mentioned in the BAA Lunar Section
circular. She comments that it might have been a meteor? The Cameron
2005 catalog ID=28 and weight=1. The ALPO/BAA weight=1.

On 1985 Dec 29th at UT 23:23-23:58, M. Mobberley (Bury St. Edmunds,
Suffolk, UK, seeing II-III) made a video scan of the Moon. P.W. Foley
examined the tape and noted something that Mobberley had not seen
visually. Two scans of Totticelli B had taken place, one at 23:23 and
the other at 23:58UT. In the first a brilliant point appeared briefly,
on the western rim, positioned at 3o'clock. In the second video
sequence this brilliant spot was present continuously and wandered
along the rim. It was possible to monitor frequency of turbulence
present, this apparent movement did not ppear to conform, although
judgement here was extremelydifficult as the feature was at absolute
point of resolution, a little better than 0.5 mile. Also considered was
the implication of the equipment effect, this did not seem to fit
either as other nerby craters in the same configuration, 30% shadow
filled with sunlight on exterior of western walls. A point to watch for
in future. ALPO/BAA weight=3.
