On 1981 Apr 15 at UT06:27-06:40 D. Louderback (South Bend, WA, USA
using a 3" refractor x134 and S=4.5-5 and T=5-0) saw a bright spot on
the western wall of Eimmart (sketch supplied) have an unusual
brightening and shade. Variations occurred over 2-3 minute intervals.
Louderback commented that the spot looked like a flare with its apex
located at the crater wall and there was some blurring effect on the
spot - it decreased in size during the phenomenon. Seeing worsened
later. Apparently on the 18th and 19th of April everything was back to
normal. Cameron comments that there is no bright spot on the Moon at
this location. Lunar Orbiter IV plates 192-3.2 shows evening
conditions. Cameron 2006 Catalog Extension TLP ID=130 and weight=3.

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.
Alphonsus 1969 Nov 20 05:27 (UT)? Observed by Argus/Astronet (San
Diego, Sacramento, CA, USA) "Brightening in crater. (San Diego &
Sacramento obs. confirmed, but astronauts did not see anything. Apollo
12 watch)." NASA catalog weight=3 (average). NASA catalog ID #1222.
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 1971 Oct 29 UT 22:15-22:50 observed by J.Coates and
A.R. Neville (Burnley, UK, 6" reflectir, x192, slight fog,
seeing jumpy but good at times). An in ititial Moonblink
search proved negative. However white light observations by
Coates revealed a golden brown colour between the black
interior shadow and the base of the (bright W (IAU?) wall).
Neville confirmed its appearance as a coppery hue and saw the
colour for 5 minutes before it vanished at 22:55UT. ALPO/BAA

(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

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

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 1987 Jan 11 at UT 18:15-23:00 P. Grego (Birmingham, UK, 6"
reflector, seeing=III) sketched Aristarchus crater and saw two
luminous circular patches on the exterior west wall - these
were less bright than the inner wall but brighter than the
outer wall. The Cameron 1978 catalog ID=292 and weight=5.
ALPO/BAA weight=2.
On 1987 Jan 11 at UT P. Moore (Sussex, UK) found the the floor of Plato
was much more drk than the adjacent Mare Imbrium. Furthemore there was
a blurring of detail over the northeast wall and onto the nearby floor.
detail elsewhere in the crater was OK. By 23:00UT there was less lack
of detail effects. M. Cook (Frimley, UK) at 21:55UT noted the obscured
area but decided that it was narrower than the same effect one month
ago and suspected that she may have been observing towards the end of
this TLP. The effect gradually dimmed between 21:55 and 22:45UT. Other
craters were normal. G. North was affected by poor seeing conditions.
Davies detected a slight obscurtion on the north east corner - it was a
misty gray feature at x200. The Cameron 2006 catalog extension ID was
292 and the weight was 5. Tha ALPO/BAA weight was 4.
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
Aristarchus W. floor was 8.0, NW wall 8.0, shadowed floor 0.0, E. outer
wall 7.0, NBP 5.5, area between Aristarchus and Herodotus 6.0, and the
comet like tail: 8.2 on the E. and 8.5 on the W. The Cameron 2006

Torricelli B 2005 Jan 22 UT 03:15-03:23 Observed by Raul Salvo
(Montevideo, Uraguay UT 03:15-03:23) showed that Torricelli B
was dark, and there was some brightness variability although the
background setting on these images was low and seeing could
account for the brightness variation? An ALPO report.

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

filter. The Moon was at a low altitude and the observation ceased at
22:25UT. P.W. Foley (Hent, UK, seeing II) observed flashes in
Aristarchus and occasional star-like points - he also observed the area
to be in a bluish translucent glow extending for about 40 miles all
around the crater. In order to check on the visibility of Earthshine, a
region of highland, near Grimaldi was checked and found to be 0.2
bright with no variations. However Aristarchus itself varied from a CED
freading of 0.6 to unmeasurable. Foley observed from 20:10-22:30UT. P.

CCD images were captured in white light that seemed to show that
the relative brightness between Aristarchus or Pytheas differed
considerably to what they were to be one night later on 2008 Nov 26.
Either Aristarchus was brighter on the 25th or Pytheas was darker.
Which feature, and which night, the abnormality occurred on is
uncertain. One possible explanation might be a brightness
gradient from glare from the sunlit side affecting the image contrast
quality of the CCD images for relative photometric measurements.
This TLP is being assigned a weight of 3 for now.

2012 Sep 24 UT 22:00-23:00 Copernicus. E. Horner (Salisbury,
UK, 15cm reflector) observed a prominent red arc where the
sunlit part of the interior wall met the shadow. Sometimes the
arc was 1/4 the way around the interior, and sometimes half of
the way around. Telescope moved, but the red arc stayed where
it was. Eyepieces change, but the effect remained. Other parts
of the Moon checked, but no red seen. There were however
splashes of green e.g. Longomontanus on the terminator,
elsewhere further inland from the termionator, and little
splashes of green on Mare Frigoras - but lasting a brief time.
The red colour was as strong as a red LED and the green similar
to that of the northern lights. The observer's husband was asked
to independetly check Copernicus and remarked that he could see
a little bit of green at the top and some red near the bottom,
along the line of the internal shadow. Although there were
checks for red elsewhere on the Moon and none were seen, the
Moon was starting to get low and it is typical of spurious
colour in a few respects. Therefore the ALPO/BAA weight=1 for
safety.

(Frimley, UK) detected spurious colour on several craters,
including Plato that night. Cameron 2006 Catalog Extension ID=
337 and weight=0. ALPO/BAA weight=1.
Arsyukhin and others (Moscow, USSR), with naked eye and binouculars
saw three dark spots suddenly appear on Mare Crisium and disappear
approximately 30 minutes later. Cameron 2006 catalog extension ID=145
and catalog weight=4. ALPO/BAA weight=2.
Arsyukhin and others (Moscow, USSR), with naked eye and binouculars
saw TLP activity in Plato that Cameron thinks confirms what UK
observers saw later. Cameron 2006 catalog extension ID=145

Alphonsus 1966 Apr 01 UT(?) 03:00-03:20 Observed by Jenning,
Harris (Coral Estates, CA, USA, 12" reflector) "Red patch from
c.p. to W. wall (no confirm. from Corralitos obs. moon blink
device & obs. at that time)" NASA catalog weight=3. NASA

Agrippa and vicinity 1878 Dec 04 UT 20:00? Observed by Capron (France?)
"Odd, misty look as if vapor were in or about them" NASA catalog
weight=3 (average). NASA catalog ID #209.
Observed by G.H. Johnstone of Albuquerque, NM, USA on 1954 Nov 05 UT
20:00 (according to Cameron), but 02:00-04:00 according to the
original observation and at colongitudes 34.7 to 35.7 deg. 4"
reflector, x150 used. The obsewrver reported that the western part
(about 1/3rd of the interior) was pitch black with shadow. However
there was a zone about as wide, or perhaps only a fourth of the total
width that was distinctly a lighter bluish shade, almost like twilight.
The shadows of the peaks on the western edge of the rim were clearly
seen crossing this bluish shadowed area. Then this area ended sharply,
and the farside was bathed in light from the rising sun. The shadows of
the peak were sharply defined across the twilight zone, and the edge of
the pitch black shadow was easily defined but not as sharp as the
darker shadows crossing the the blue twilight zone. The observer
checked other craters but did not see this condition in any of them -
they all had the abrupt division between black and white that we would
normally expect to see. Cameron 1978 catalog ID=579 and weight=2.

Censorinus 1969 Nov 19 UT 1922 Observed by Brandli (Wald,
Switzerland, 6" reflector, x90) "Brightening -- photo, (the
author, WBC, cannot verify from photo. It is brighter, but so
are Proc. & Dionys. -- it being between. i.e. Proc. > Censor. >
Dionys. Apollo 12 watch)." NASA catalog weight=5 (very high).
