On 1983 Mar 21 at UT 21:05-22:00 P. Horne and J. Horne (Hertz, England,
UK, 11" reflector, x180 and x330) found that Mons Piton (totally
illuminated and brightest feature on the Moon - but no variability) was
brighter than Aristarchus (would have been if it had been in sunlight)
and the mountain was contained within a circular illuminated patch.
"Brilliant white and no shadow. Size ~16km." There was no details
visible but the adjacent features had distinct shadows. Hutton was also
observing. Foley examined the photographs and believes that they are
inconclusive. D. Mansbridge was photographing the Moon at 19:30UT and
detects Piton but it is not bright. However in a photograph taken by D.
Mansbrdige and 20:30UT the mountain is much brighter than any other
sunward facing slopses on the northern part of the Moon's terminator.
R. Mosley had been observing earlier at 18:10-19:40 and although
finding the mountain to be shining briliantly beyond the terminator, he
also comments that this is normal. Cameron though has seen the

observation was reported in the Astronomical Register of the Royal
Astronomical Society and is not included in the Cameron catalogs. It is
one of many measurements of the brightness of this spot for different
illumination angles and is one of three outlying brightness points
spotted on a graph by Willaims. The ALPO/BAA weight=3.

On 1969 Nov 18 at UT 00:30-02:30 W. Cameron (Greenbelt, MD, USA, 12"
reflector, x80 and x320) using a low power eyepiece, observed that
bright craters (but not all of them) "glittered like diamonds". These
craters were several on the terminator, Proclus, Censorinus, Manillius,
Menelaus and Dionysius. The glitter effect was on the west wall crest
-- like stars. Higher power revealed these areas to be bright but not
star-like (nor glittering). The Cameron 1978 catalog ID=1212 and the

Plato 1789 Jul 30 UTC 21:00? Observed by Schroter (Lilienthal, Germany)
NASA Catalog Event #61, NASA Weight=2 (slightly low) Event described
as: "Soon after sunrise saw a kind of fermentation on the floor which
clearly resembled a kind of twilight, (due to some kind of aberration
unknown to the observer?)" For further details see reference:

Eratosthenes 1952 Nov 25 UT 16:30 A.P. Lenham (Swindon, UK, 3-
inch refractor x150, Definition Good) noted that there was
faint/slightly bright detail inside the interior shadow -
observer comments "presumably peaks of central mountains & W.
Wall ridge, but very faint" - however this is worth checking
out. ALPO/BAA weight=1.
On 2009 Nov 25 UT18:42-21:03 P.Abel, T.Little and C.North (Selsey, UK,
15" reflector, seeing II-III, transparency very good), all saw visually
a brownish tinge on the north west rim of Eratosthenes crater. P.Abel
made a sketch and T.Little took some high resolution CCD images, some
of which were through coloured filters. Checks were made for spurious
colour, but none was seen elsewhere on the Moon. The eyepiece was
changed but this made no difference. M.C.Cook (Mundesley) was observing
with a smaller scope at the same time, but saw no colour, however
observing conditions were worse. W.Leatherbarrow (Sheffield, UK) was
observing with a instrumenet mid way in size, and saw a brownish tinge
in the NW rim area, but saw a similar colour elsewhere and put this
down to spurious colour. Normally multiple observers seeing the same
thing would result in a weight of 4, however as this was only observers
at Selsey and some of the evidence contradicts, I am allocating an
ALPO/BAA weight=3.
On 1960 Aug? 01 at UT 22:00? an unknown observer detected that Vitello
was illuminated -it should have been in shadow? Cameron says that if
several days before sunrise then the date could have been July through

P. Moore at 21:10 found the southern wall (and ontothe southern floor)
of the crater to be indistinct. Elsewhere in the crater everything was
sharp. The effect was still seen at 21:42UT, but less strong. A check
was made for colour with aq Moonblink device, but none was seen. There
was still a trace of this effect at 21:44UT, although detail was now
becoming visible. By 21:48UT vertical streaks were seen crossing
the floor from the obscuration area and these were more visible in the
red filter and not in the blue. Cameron comments that undefined patches
on the floor of Plato are not normal. By 21:55UT some craterlets on the
floor started to become visible and the TLP for Moore ended by UT22:23.
P.Foley was alerted by Moore and saw a "amssive dense obsecuration
on the south wall, south floor and south outer glacis to the Mare".
Foley noted that by 21:50UT the effect was fading and finished by
22:03UT. Foley reported an orange translucent haze covering half of the
floor, but floor craterlets could be seen on and off - however his
atmospheric seeing conditions were IV. At 22:00 UT Foley reported the
floor close to the north wall to be "milky or misty". No detail was
visible at 21:15UT and variability in the floor continued until
23:10UT. Hedly-Robinson was aleted at 21:35UT and found no difference
between red and blue views of the area, however he did find that the
south rim was indistinct although this effect had lessened by 22:00 UT
and was normal by 22:17UT. M. Mobberly saw a white spot on the floor at
21:20 UT, whereas he normally would have expected to see craterlets.
Mobberly was alerted at 21:40 UT and took some colour photos. He also
made sketches that showed variability in the floor and dark lines and
patches in the north west corner. However the altitude of the Moon was
low. Cameron mentions that two of the photos show loss of detail at the
south wall and beyond.and also a change in the floor markings.The north
wall at 21:50UT was strangely reddish (didn't think this was spurious
colour). The rest of the wall was sharp at 22:20UT through a yellow
filter. Large bright patch in the centre and rest of the floor was
apparently of the same shading as Mare Imbrium. The above notes are
based upon the Cameron 2006 catalog extension TLP ID 145 and weight=4.
ALPO/BAA weight=3.
Piton 1969 Nov 19 UT 21:15-22:00 Observed by Baum (England,
4.5" refractor) "Traces of cloudiness on E. slope at 2115h.

C. Brook of Plymouth UK, using a 4" refractor x216, noticed at UT 20:10
dark patches coming and going (in terms of visibility) on the floor of
Plato. Occasional views of the central cratelet (seen as a white spot)
were glimpsed. The dark patches seen lasted about 1-2 seconds before
fading out during each visibility cycle. Teneriff Mountains were
checked but no sign of seeing effects that might explain the dark floor
patches. By 20:26UT the dark patch effect was fading and by 20:31UT
floor detail was visible. Observations ceased at UT 20:34. Seeing
conditions were II and the Moon was at a high altitude. Other observers
were alerted but came on-line after the effect had finished. ALPO/BAA
weight=2.
At approximately 18:43UT observer noticed that Censorinus, and
its bright apron, appeared particularly brighter than normal.
There was some spurious colour present - but just a redness
along the southernmost extent of the apron visible; could not
detect any blue along the northern edge however, he did do not
suspect the colour to be anomalous. A re-examination at 18:51UT
revealed that the crater had faded and was seen to fade visibly
in real time to normal levels (over about a minute) by 18:53UT.
Other features remained constant and so too did the apparent
spurious colour.
Eratosthenes 1968 Nov 01 UT 01:50-02:06 Observed by Chilton
(Hamilton, Canada, 12" reflector, 300x) "Red glow in the crater.

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."
Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon,
England) - observer noted that the east outside wall was bright in red
and normal in blue. Note that the Moon was 30 deg above the horizon at
the time of the observation. The crater returned to normal at 20:58.
Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D.
Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at
times) noticed a possible obscuration over the southern part of
Gassendi. He had been observing earlier at 18:40-19:30 but had not
detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot
outside the east wall is again bright in red., though by 22:25 it had
faded and was gone by 22:28UT. The Cameron 1978 catalog further
quotes: "Vivid red spots & general red color seen around rim by 2 obs.
At 2209h blood red small area was seen. 1 h later the most westerly
(IAU?) of the peaks had become hazy white all other areas were sharp.

On 1984 Jan 14 at UT 20:00 P. Moore (Selsey, UK) observed that
Aristarchus was brighter than it normally is at sunrise. No
quantitative measurements were made though. The Cameron 2006 catalog
ID=238 and weight=3. The ALPO/BAA weight=1.
Observer noted a bright spot on the interior west wall that seemed
brighter than what they would have expected. unfortunately the precise
time of this observation was not recorded so the moon-rise and
midnight UT values are used to place a limit on the time of
observation. Images by Shaw taken at UT 1754, 18:45 and 23:13
do not exhibit the effect.
On 1978 May 18 at UT20:45-21:53 J.D. Cook (Frimley, UK, 12"
reflector, x240) observed Promitorium Laplace to have
visually a brown colour - though no Moon Blink (red and blue
filters) effect was detected. Cameron comments that this is
probably a subjective effect - also others have reported
something similar at times. The Cameron 2006 catalog ID=30
and weight=3. The ALPO/BAA weight=1.
Plato 1998 Jul 05 P. Moore (Selsey, UK, 15" reflector, x200-

tonight. The ALPO/BAA weight=1.
On 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6"
reflector) took some photos (albeit out of focus) that showed a bright
spot on the west rim. Cameron comments that this spot was sharp
compared to the rest of the photograph, so was probably a photographic
artifact. The effect was not seen in the finder scope. The Cameron 2006
catalog ID=103 and weight=2. The ALPO/BAA weight=1.

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.
On 1889 May 11 at 22:00? UT an unknown observer saw an ink black spot
on the rampart of Gassendi. It had not been seen before ar at the next
lunation or indeed ever again. Cameron 1978 catalog ID=261 and

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

On 1990 Oct 1st at 00:44-01:24UT D Darling (Sun Praire, WI, USA)
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
outer E. wall 8.0, the N. floor 5.5. Gassendi A W. wall was 9.5,l

Seen" BAA Lunar Section Observation. ALPO/BAA weight=2.
Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore
(Sussex, UK) saw the wall as normal. However Cameron points out that
Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely
(Covington, UK) at 22:10 UT noticed a brightening on the East wall and
at 01:10-01:25 UT suspected that the interior had a weak yellow-green
cast to it. Cook (Frimley, UK) states that orange colour was within the
interior crater, but green beyond the east rim at the 9 O'Clock and
the south east corner to floor blue/mauvre beyond the northern rim
NW/WSW. Foley sstates that orange and blue/mauvre might be spurious
colour, but green one cannot get this way. Cameon suggests chromatic
aberatons as a possibility but thinks that the observers concerned were
experienced enough to recognize this if it were the cause. Cameron 2006
catalog extension ID=239 and weight=0. Moore used a 15?" refletor and
Foley used a 12" refletor. Mosely experienced II seeing and good

On 2016 Jul 17 UT 03:49 P.Zeller (ALPO, Indianapolis, IN, USA)
imaged a pseudo-peak with shadow on the floor of Herodotus,
however the image scale and quality of this colour image were
not great and the observer suspects that it might be an
imaging artefact. ALPO/BAA weight=1.

P. Foley of Kent, UK, using a 12" reflector, seeing=III-II, noticed
that initially that the crater was pretty dull and that the floor
was a slate blue-gray in colour at 22:45UT. A noticeable green spot
inside the crater on the south east appeared at 22:25UT and vanished
at 00:50UT. Cameron notes that one doesn't get green with spurious
colour. Crater Extinction brightness measurements were made at 22:00 UT
(reading=2.8) and at 23:45UT (reading=3.7). The crater dropped in
brightness from 3.7 to 2.8 at 23:50UT and remained lower until 3.0 at
23:50-03:15 UT. A graph was produced and showed Proclus and Censorinus
at similar brightnesses, but Aristarchus variable. The Earthshine was
0.3. Cameron 2006 Extension catalog ID=31 and weight=5.

On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK,
seeing=IV-V, transparency=good, spurious colour seen) found 2
bright pathces on the east rim on alternate sides of a bright region.
The band from the central 16km wide region was dark on the east side.
Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be
not as bright as normal, apart from the band that Mobberley found (1
hour later). The dark regions were a murky green colour (bright through
green, blue and yellow filters and dark through red and orange
filters). Cook (Frimley, UK, transparency=excellent, CCD camera used)
found a bright "bulge"on the eastern side. Apparently data suggests
that the band was brighter in red than in near IR light. Cook's
calibrated brightness measurements suggest that there was no change in
brightness over the crater with time. Two other bright points were
seen: one at the Cobra's Head and another half way between the east rim
of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87
(near IR) and combined Wratten 29 and Wratten 87 were used. In the red
Wratten 29 filter the brightness falls at22:20 at Shroters valley and
then rises in the bright ray. They return to normal at 22:30UT. There
was however a lot of measurement noise from the brightness readings of
points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The
ALPO/BAA weight=3.
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
were as follows: Darling (Sun Praire, WI, USA, 12.5" reflector, x159,
S=9/10). D. Weier (Sun Praire, WI, USA, 12.5" reflector, x159, S=

Cobra Head 1955 Oct 31 UTC 19:00 Observed by Milligan (England?) "Dark
blue obscuration" NASA catalog weight=3 (average). NASA catalog ID 624.
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.

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

weight=2. NASA catalog ID #499. ALPO/BAA weight=1.
On 1986 Feb 26 at 05:00UT a photograph was obtained by T. Kohman of
Pittsburgh, PA, USA (3.5" Questar and 0.25 sec exposure) that had two
bands above the limb, resembling ejecta plumes. Cameron suspects that
these are probably flare from the eyepiece optics. Cameron 2006

invis. (similar to #394, 396)." NASA catalog weight=4 (high). NASA
catalog ID #412.
Plato 1938 Jul 15 UTC 06:50 Observed by Haas (12" reflector?) "Floor --
definitely green under same conditions as 5/17/38 (see #437). Kaiser
after 90 obs. couldn't find any regularity to appearance of the brown
color in Plato. I=3.7 comp. with I=2.0 on 6/15/38 (see #439-- color of
ground?)." NASA catalog weight=4 (good). NASA catalog ID #440.
On 1961 Jul 01 at UT 00:00? an unknown Miranova (Russia or
Israel) obtained some spectral photometry of lunar objects. A
spectral plate in 425 -> 500nm bands. The Cameron 1978 catalog
ID=743 and weight=5. The ALPO/BAA weight=3.

clouds" NASA catalog weight=4 (high). NASA catalog ID #1233
Area of darkness overlapping NW rim. It was visible through
this area of obscuration. Sketch. Cameron 2006 extended catalog
ID=376 and Cameron weight=3. ALPO/BAA weight=2.
