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

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.
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.

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.

On 1983 Apr 19 at 21:45UT M.C. Cook (Frimley, UK) reported that
Censorinus' exterior white patch was grayish at this time and there was
a "momentary glow outisde the crater to the North West. The Crater
Extinction Device brightness measurement for Censorinus was 4.0 whereas
Proclus was 4.4. Cook was expecting a lower CED brightness measurement.
Foley notes that Censorinus is usually brighter than Proclus. On 1983

bright points about 5 magnitudes brighter than any other part of the
Moon. The Alpine valley points directly between these two points. "Came
from apparently featureless area. Both points about the same size, but
different shapes ~ width of alpine valley" The observer used 4
different eyepieces and the points were brightest in the lowest power.
Other specks of light could be seen in the darkness wound the N point.

weight=2.
On 1979 May 04 at 21:30-22:00UT Coates detected a star-like point
inside Hipparchus L crater using averted vision. Cameron in her 2006
catalog extension comments that Hipparchus L is a highlands impact
crater with a rille on the western ejecta blanket. The crater is the
smallest one in a chain that are sequenced to be half the size of the
previous crater in the chain. Apparently the largest crater in the
chain is Hind with a largely landslide covered floor - although on the
south is a dome? with a summit crater. Cameron's 2006 catalog extension
gives this TLP an ID of 51 and a weight=2. The ALPO/BAA weight=2.

Hart & others (Glasgow, Scotland, 10" reflector), "2 luminous
fiery spots on bright side on either side of a ridge,
contrasting color. Seemed to be 2 active volcanoes. Ridge was
normal color. Spots were yellow or flame color. Never seen
before in 40 yrs. of observing." Please try to observe this

On 2003 Apr 10 at 00:40UT a GLR observer G. Jasmin (Quebec, Canada,
using a 10" F-10 Schmidt Cassegrain) took a photograph of Alphonsus
crater on Kodak 400ASA film with an exposure of 1/30th sec. There was a
light visible (diameter 10 km) inside Alphonsus and the effect was
present for 5 minutes. The observer commented that they have seen a
light in this crater many times before, but never as long as 5 minutes.
This report was submitted to the GLR group in Italy. The ALPO/BAA

On 1983 Apr 21 at UT 21:55-22:05 N. King (Winnersh, Berkshire,
UK, using a 150cm f/8 reflector, with seeing I and
transparency good, little spurious colour, just a little in
Plato). Although observing since 21:25UT the observer noticed
a just detectable faint green colour just after the dark shade
around the inner eastern crater rim. The effect faded and by
22:05UT had completely gone. This report is not in the Cameron
2006 catalog. It is a BAA report. The ALPO/BAA weight=1.
Although the crater was on the night side, a small bright spot
was seen. This was blue, almost UV, and equivalent to a star of
magnitude 2. It flashed over intervals of about 30 seconds
and changed in colour from UV to blue. The BAA Lunar Section
TLP network was alerted. Mobberly and J.Cook did not see much
although J. Cook may have seen something, but located else where?
Cameron lists this as a confirmed? observation? The Cameron
2006 TLP xtension catalog has this TLP with an ID No. of 258
and a weight of 4. The ALPO/BAA weight is 2.
On 1983 Feb 21 at 20:00UT P.W. Foley (Maidstone, Kent, UK, 12"

C11, Transparency 3, Seeing 7-8, 86F and very humid. Oberver
checking out repeat illumination condition appearence for Tycho
concerning LTP #468 in the 1978 Cameron catalog. Did not see the
effect from the original TLP report, but did see, immediately at
looking at Tycho a very faint hint of redness in a pencil thin
arc (< 1/4 circumference of the rim) confined to the top of the
rim of the well-lit north east wall. Coloured arc similar in
thickness to Rupes Recta, but not as sharply defined. The outer
(E) edge was perhaps sharper than the inner edge. The redness
was more on the inside of the top of the rim. The outside of the
rim was bright white. This effect was seen in three different
eyepieces, at 311x, 224x and 400x. Checked for the effect on
other craters nearby but could not see this effect anywhere
else. The colour had dissapeared by 01:02UT. The fade took about
1-2 minutes. Observation of Tycho continued until 01:06UT, but
all seemed normal. Quick checks were made again on Tycho
periodically until 02:50UT but the colour was not seen again.
ALPO/BAA weight=3.
