Om 1987 Sep 04 at UT 03:00 J. Caruso (Middletown, CT, USA, 3"
refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not
visible, however Heraclides E, Helicon G, and indeed many other smaller
craters could be seen. There were two small mountains in the general
area of Bianchini G. and a mare ridge - all these were clearly seen.
Caruso states that Bianchini G should normally be much more clearly
seen than the other features mentioned and is the same size as
Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3. The

exposure 0.003 sec) saw on a computer monitor screen a flash
to far to the west of Herodotus and Aristarchus at the
location 54.53W, 23.5N. It had a duration of 0.5 sec and on a
brightness scale of 0 = night side of the Moon to 10 =
Aristarchus, ranked 7. Unfortunately they were not recording
at the time. As there was no confirmation observation and it
could be a cosmic ray air shower detection, the ALPO/BAA
weight=1

On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector,
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
times and these times need to be correctly converted into UT? The
Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.

On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in
Gassendi - some obsevers detected colour, others did not. P. Moore did
not notice anything unsual earlier at 18:50-19:00, though his seeing
was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing
was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also
reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did
however notice a small reddish spot to west of central ridge, but by
20:30UT the colour was less obvious, but the spot was back again at
20:45, but not easily seen at 21:00 and gone completely by 21:45UT.
N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red

On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK,
12" reflector, x200, seeing=II) noticed in the area south east of
Manilius that it was brighter in red light than in blue light at
20:15UT whereas 1 minute later it was the same brightness in each
filter. The effect reappeared at 20:21UT and was particularly strong at
20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was
of high reflectivity in white light and was bright in red at 21:15UT,
thougjh the south east area stopped giving a colour reaction at
21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT
however at 23:55UT it was surrounded by a transient white ring that
varied in visibility in an irregular way. Foley found Manilius B had a
vivid blue interior and in blue light the ring was black. and not at
all seen in red or white light. The CED brightness measurement varied
from 1.9 to 2.4. All other regions observed were normal in brightness.
Violet was seen on the west wall of Aristarchus though. M.Price
(Camberley, UK) found a possible blink in Manilius B but was observing
under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5.

Argentina, 105 mm Maksutov-Cassegrain, x154, seeing 6/10, some
interuption from clouds) observed a light spot SE of the
centre of the floor of the crater, which came and went in
visibility. There is a light spot here, but what was unusual
was that the visibility decreased over time.

Aristarchus 1982 Nov 27 UT 20:13-01:00 J-H Robinson (Teighmouth, Devon,
UK) found that the bands of Aristarchus were clearer in red than in
blue light. North found that the sunlit part of the crater was very
bright. M. Cook described the crater as a "kaleidoscope of colour.
Foley observed UT 23:05-01:00 (Kent, UK, Antionadi III, Transparency

The ALPO/BAA weight=2.
On 1975 Apr 23 at UT 20:30 J-H Robinson (Teighmouth, Devon, UK, 260mm
reflector, x200). Observer was observing since 20:30UT, at 21:00UT
though they noticed red on the outside south wall of Aristarchus, a
hazy ill defined area that was larger in a red filter than in blue
filter, and outside east wall was bright in red. At 21:08UT the outside
west wall of Aristarchus no longer gave a colour blink reaction, and at
21:22UT the colour blink on the southern end of the crater ceased, but
the image blur remained (in both red and blue filters) despite the rest
of the crater being sharp in detail. Observations ceased at UT 21:35
because the blurring at the southern end seemed to be normal and this
was confirmed when checked with photographic atlases. Other craters
such as Proclus, Pickering, Tycho, Gassendi, Copernicus, Alphonsus,
Plato, Menelaus, Manilius, Linne and Theophilus, showed no colour blink
reactions. However Picard had a red bright blink from 20:30-20:40 and
the permanant blink on the N. Floor of Fracastorius was detectable.
Also Plato floor shadings were clearer in red than in blue -
intermittently. This is a BAA lunar section observation. No estimation
of transparency or seeing is given, nor any comment on whether spurious
colour was seen in any craters visually. 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.
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.

x286) observed that east of Lichtenberg were ëxtensive rosy areas"
around the northern edge of the lava sheet. Hill believes that it may
have been the same effect as seen by Madler (Germany), Barcroft (USA)
and Baum's (UK) 1951 observation. The colour was "ünmistakable" and
nothing to do with the atmospheric spurious colour. Other features were
checked. the cameron 2006 catalog ID=322 and the weight=3. THe ALPO/BAA

transparency, good) noticed in Aristarchus, blue to the north west
(IAU?) internal wall, also blue observed in other small bright objects
against dark backgrounds. Lunar rotational axis and optical normal
related such that the normal runs NW-SE (IAU?) through these features.
Observer deduced that the coliur was obviously spurious and no blink
was seen in any feature. The blue disappeared as the lunar altitude

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.
The ALPO/BAA weight=1.
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

the Moon during a lunar eclipse (including Aristarchus). At 23:50UT
Aristarchus was an oval shape with no details seen. It had a ray
extending from the south west rim (normal). The north rim was slightly
blue and the south west rim very very slightly red. At 23:55UT it was
clearing and details showed. At 00:02UT it was clear. Sketches were

(Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max,
with 2x teleconverter, at f9, 1/320 sec, ISO 400 – tripod
mounted, mirror up), A series of images were taken. The 21:06 one
showed a grey column cutting across the central floor of the
crater from the west and then bisecting the eastern rim. All
detail inside is completely invisble. Some (but not all) of the
other images showed a more blurred view of this feature. It's
possible that this was a seeing ripple effect, or just the
natural appearance of shadings on the Moon at this time, however
for now this will be given an ALPO/BAA weight of 1.
On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade
2045 reflector, x40, seeing=turbulent) detected flashes coming from
just north of the centre of Mare Tranquilitatis. Some of these flashes
were of a duration of seconds whilst others were several minutes.
Altogether ~20 flashes were seen, and not in the same place. "5 small
star-like points could be located - and there were lots of craterlets".
The spots were "lined up E-W at N of 10 deg latitude." Colour was not

south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected
it easily. At 01:33UT the colour was barely visible. No TLP alert was
issued because the souther edge of Mons Pico also exhibited a hint of
colour, and anyway the seeing conditions were poor. Despite this no
other features revealed colour. The Cameron 2006 catalog ID=446 and the

ALPO/BAA weight=1.
Heywood of Wheatville, Ohio, USA, using a 2" refractor under fair
seeing conditions, saw a misty light on the dark limb (similar to
Cameron's 1978 catalog TLP 239). The effect had narrowed down on the
30th. Cameron comments : "old moon in new moon's arms?". Cameron 1978

On 1970 Jul 06 at UT 22:45-23:45 Celis (Paso Hondo, Chile, 3"
refractor, x60, x100, x135, seeing=very good) saw Aristarchus as an
outstanding bright patch (10 deg bright) electric blue colour, every 10
sec groups of 3 or 4 separate sparkles for 10sec then a period of calm
for 30sec-1min. At 130x was almost constant form. Sometimes the form
would be radial like an open band with extended fingers. This was
observed in the dark part of the Moon and Cameron suspects atmopsheric

Om 1990 Mar 01 at UT 00:59-02:20 D. Darling (Sun Praire, WI, USA, 3"
refractor, x36) observed that Aristarchus could barely be seen, but at
02:15 UT it brightened by about two times. Note that brightening might
refer to Lambert - it is worded in an ambiguous way in Cameron's
catalog). The Cameron 2006 catalog ID=392 and weight=0. The ALPO/BAA

Proclus C region 1985 May 23 UT 17:41 Photographed by Kolovos (observer
from Thessoloniki, Greece, observing site near Bafra Serrain, Greece,
4"refractor, seeing excellent) "Observer took a series of expousres on
a portable scope of the Moon. On one of them a very bright slightly
elliptical spot was seen. Spot was very close to the Proclus C crater.
Upon analysis it was claimed that the spot of light had rotated the
direction of illumination of shadows in adjacent craters - however
subsequent analysis casts doubt on this. Papers on this report
were published in Icarus. Rast and Maley suggested that it was sun
glint off a spinning US ex-military weather satellite that just by
chance came across the field of view of the Moon a few tens of seconds
around the time of the photographed flash. Was this a coincidence or
not? If it were a satellite sun-glint then the satellite would have to
be tumbling incredibly fast in order for the flash to be so sharp in
the photograph - so the satellite explanation is not completely 100%
confirmed." The Cameron 2006 catalog ID=273 and the weight=5. The
ALPO/BAA weight=2.
On 1885 Feb 19 at UT 19:00-20:00, Gray of England?, saw a small crater

On 1970 Jul 08 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3"
refractor, x60, x100, x135, seeing=excellent) observed the following at
Aristarchus: "Conditions again similar (to #1264). Brighter tonite(8
deg) than last nite. but not as bright as on the 6th. Pin pts. of light
very accentuated. The radial open hand extended fingers form not so
frequently, perhaps because of the larger crescent illum. now.".

"Noted a fuzzy, glowing spot at 1936h at 160x. 2 min later, spot
grew larger & flashed up to very bright. Changed power to 106x,
& 80x, still vis. Spot faded 10 m later, then suddenly flashed
up again. 5 m later it faded again & disappeared at 1959h. At
2006h returned to fuzzy, glowing spot then disappeared at 2009h,

afterward don't show anything, nor did blink aftwerward." Moore
though nothing unusual. NASA catalog weight=5. NASA catalog ID #
1431. ALPO/BAA weight=3.
On 1965 Oct 30 at UT 0200 Eastman (Palos Verdes, CA, USA, 12"
reflector) observed a brightening in Aristarchus in ashen light. The
photographs that were taken show it. The phenomenon was seen each
lunation since July. The Cameron 1978 catalog ID=908 and weight=5. The
ALPO/BAA weight=2.
Cyrillus G 1983 Aug 13 UT 20:17-20:59 L. Paynter (Radcliffe,
UK, 22cm reflector, seeing III or better, transparency good).
Cyrillus G was relatively bright and surrounded by a shaded
area. On increasing the magnification from x65 to x130 he became
aware of a diffused "carise" colouration, in and around the
crater. The colouration was similar though to other spurious
colour on the Moon, but unlike other areas affected by spurious
colour, was more diffuse and spread out and not so concentrated.
In view of some uncertainty by the observer, ALPO/BAA weight=1.
On 2009 Mar 01 at UT 18:50-21:00 G. Smith (East Yorkshire, UK, 127mm
Maksutov Cassegrain telescope with zoom eyepiece and later a Plossl
eyepiece) observed an area between Plato and Sinus Iridum to be glowing
as a bright nebulous patch. It was brighter than anything else in
Eartshine. A change in eyepiece did not affect the appearance of the
nebulous patch. The patch had faded somewhat by 21:00UT. The observers
brother attempted to observe the patch through a 114mm reflector at
20:30UT but the optics were of poor quality and the effect was not
seen. BAA observers were alerted, but only after the event had faded -
they made observations from 22:00-23:46 UT but failed to detect
anything unusual in the region concerned. The ALPO/BAA weight=1.
This may have been a mis-identification with Aristarchus - however
we cannot be 100% sure.
In 1965 Jul 04 at UT 03:53-05:59 Gridley, Welch (West Covina, CA, USA,
4.5" and 8" reflector, seeing=excellent), Albert (CA, 8" reflector,
x375) and Emanuel (8" reflector) observed star-like flashes in
Aristarchus crater. Cameron says this confirmed and that the date
in MBMW is 7/3/65 which is local time = 4th UT also but is in error due
to misreading of handwriting. The Cameron 1978 catalog ID=883 and
weight=3. The ALPO/BAA weight=3.
Posidonius 1821 Apr 07 UTC 18:00? Observed by Gruithuisen (Munich,

On 1965 Oct 30 at 23:30-23:50UT Fehring and Garris (Parasmus, NJ, USA,
using a 2.4" refractor x88, seeing very good) saw a fuzzy area --
variations in shape and distinctness, seen in an area east of Atlas
crater. A drawing was made. It was noted that no other area had a
similar effect. Cameron 1978 catalog ID=909 and weight=3. ALPO/BAA
weight=3.
On 1991 May 19 at UT 22:59 M. Cook (Frimley, UK, 12"? reflector,
seeing III-IV) noted that Censorinus was a dull greyish white in
colour and the apron was not diffuse. The Cameron 2006
catalog ID=426 and the weight=1.
On 1994 Apr 17 at UT02:00 R. Zit (Madison, WI, USA) whilst observing a
grazing lunar occultation, found that Aristarchus (and the surrounding
region) was glowing in Earthshine. This was confirmed by D. Weier
(Madison, WI, USA) at 02:00 UT also. The ALPO/BAA weight=1.
On 2012 Mar 28 P. Grego (Cornwall, UK, seeing II, 100mm
refractor, x132) observed a patch of light just inside the NW
rim of Menelaus on the shadowed wall or floor. Computer
visulaiztions of the illumination conditions using a digital
elevation model failed to produce this effect. 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.
Pitiscus 1981 Sep 05 UT ??:?? but assumed to be AM? which would make
it 00:00-03:00UTC. Observed by Slayton (Fort Lauderdale, Florida, USA,
8" reflector, ASA 64EK7 f/170, Kodak Kodachrome) photographed a bright
glow in the crater that appeared to move. Observer also reported seeing
it visually noting that it looked gray with a tinge of red. For further
information see p266 of Sky & Telescope (1991, March). Note that
Cameron gives the date and UT at 1981 Sep 06 UT 01:00-01:30, or one day
later. I will use this date and time from now on. The Cameron 2006
catalog ID=152 and weight=5. The ALPO/BAA weight=3.

Albategnius 1972 Jun 18 UTC 19:20-19:25 Observed by Schnuchel (13.25E,
52.5N, 20x60 binoculars?) "Bright area at the inner N wall, diminution
of brightness well observable" S=4 T=4. Ref: Hilbrecht & Kuveler Moon &
Planets (1984) Vol 30, pp53-61.
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.
A.S.Williams of West Brighton, UK, using a 2.75" Acromatic refractor
(x75, definition good, but it was too windy to use the 5.25") noticed
that the mare was a mass of light streaks and spots. This was not
considered unusual, but these features were unusually plain, distinct
and brught, especially the streaks. The observer could not recall
seeing the streaks so bright and clear with this instrument before, and
indeed hardly ever with the larger 5.25" telescope. The observer
continued to observe Mare Crisium on many nights for several months and
comments that such an unusual exhibition was later seen perhaps once
every 2-3 lunations. They are uncertain how much this effect depends
upon the state of the Earth's atmosphere. This TLP does not make it
into the Cameron 1978 catalog and so may not be a TLP - however it has
been included, just in case, and to try to understand what was actually
seen. ALPO/BAA weight=1.
Proclus 1972 Jun 18 UTC 20:50-21:15 Observed by Kern (8.75E, 48.25N,

A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and
definition fairly good. Observer noticed that the Mare seemed covered
with a close network of innumerable streaks, and spotted with countless
numbers of light specks, so that it would hardly be possible to
delineate them all in one night. The spots and streaks together must
have numbered ~1000. The observer had never seen anything like the

strangely bright and pink/red north rim of Aristarchus crater during
UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT.
M.C. Cook (Frimley, UK) found the northern wall to have a red/purple
colour but the effect vanished after 50 minutes. Cook also saw a "V"-
like notch in the NW crater shadow and this appeared to be bigger than
normal. G. North (Sussex, UK) saw a tinge of pink colour on the
northern rim and a bit later a "ruby red" colour on the north-west wall
- again this effect lasted 50 minutes. Moseley verified the colour.
Finally M. Hather (Yorkshire, UK) suspected the north wall of
Aristarchus to be blue in colour. Cameron suspects that this TLP is not
spurious colour because it is in the wrong place. The Cameron 2006
