Lichtenberg area 1940 Oct 18 UT 07:11 Observed by Barcroft
(Madera, CA, USA, 6" reflector) "Pronouced reddish-brown or
orange color, less marked on next nite, & slight on 22nd, see
#'s 477, 478." NASA catalog weight=3. ALPO/BAA weight=2. NASA
catalog ID #476.
Plato 1966 Sep 02 UT 0625 Observed by Kelsey (Riverside, California,
USA, 8" reflector x300) "Landslip at west would not focus. (Ricker not
certain it was a real LTP)." NASA catalog weight=2 (low). NASA catalog
ID 973.
Aristarchus 1983 Oct 23 UT 19:00-01:30 Observer: Foley (Kent, UK,
12" reflector, seeing=II) noiced at 19:00UT an extended bright
spot on E wall and extending beyond. This was brighter than other
areas of the crater. There was also occasional star-like
glistening. Foley comments that the inside of Aristarchus was
slightly obscured. The TLP started fading from UT20:30 and
finished by 01:30UT. six out of nine independent observers
confirmed the effects seen. In total 14 observers observed, 9
reported back and 6 found abnormalities in Aristarcus though all
encountered variable seeing conditions - some had spurious
colour. Cameron comments that this was one of the best
recorded/confirmed TLP events. All CED brightness measurements
obtained were very high. Moore, Nicolson and Clarke (5" refractor
and 15" reflector, 230-350xseeing III) found the crater to be
very bright at 19:11UT through a 5" refractor and there was a
blob on the east rim (Bartlet's EWBS?) at 19:14UT. Nicolson also
saw a very bright star-like area on the eastern wall but this was
not defined as it usually is. The crater was also very bright at
22:43UT using the 15" reflector available to these observers. At
01:07UT they used a Moon blink and discovered that the bright
region was bright in blue light and less bright in red - although
this was not a detactable blink when switching rapidly between
filters. They found that the crater had returned to normal by
01:15UT. M.C. Cook (Frimley, UK, seeing III-IV) observed a large
diffuse spot on the east of the crater that was brighter in blue
than in red light and the CED device gave a high reading. J.D.
Cook (Frimley, UK, seeing III-IV) made a skecth that showed the
bright spot extended on the east wall - again the CED reading was
high and a lot of detail was visible on the floor. A.C. Cook
(Frimley, UK, seeing III-IV) also noted remarkable detail and the
bright (as confirmed by CED) blob on the eastern rim. G. North
(Sussex, UK, seeing III-II) also confirmed the bright blob on the
eastern wall. Wooller found the north west wall was a dirty
yellow colour - though no colour was seen elsewhere in or outside
the crater. Mosely found the crater to be bright and his sketch
revealed the extension of the bright blob on the eastern rim and
again a great deal of interior detail. Amery (Reading, UK, seeing
III) found Aristarchus to be "a brilliant splash against dulled
background in violet filter, especially polarizing filter. CED +
polarizer readings high, but not as high as previous night".
Mobberley (Suffolk, UK, seeing III-IV) remarked that "spurious
colour a total mess around Aristarchus & nothing abnormal seen".
A photograph was taken at 20:50UT reveals the bright blob and
entire detail. Peters (Kent, UK, seeingIII-II) observed
Aristarchus with a UV screen from 20:15-21:23UT and comented that
althogh being very bright, there was no variation between white
and UV. It was checked with a Moon Blink device and the radial
bands were clearly seen in white light, < in blue. The Cameron
2008 catalog ID=233 and the weight=5. The ALPO/BAA weight=4.
In 1950 Jul 02 UT07:22 Bartlett (Baltimore, MD, USA, 3.5"
reflector) saw no dark bands on the inside of Aristarchus,
despite detail being seen elsewhere. He would normally have
expected to have seen bands at this colongitude, based upon past
observations. The ALPO/BAA weight=2.
Aristarchus 1964 Oct 23 UTC 02:35-02:45 Observed by Bartlett
(Baltimore, MD, USA, 3" refractor, 133 & 200x, S=3-5, T=4) "South floor
region granulated, 6 deg bright with very faint trace of pale yellow
color; rest of crater 8 deg bright." NASA catalog weight=4 (good), NASA
catalog ID #859.
On 2002 Sep 23 at UT22:45-23:56 C. Brook (Plymouth, UK) noticed that
the bands inside Aristarchus varied (UT22:45-22:56) in definition
whilst the rim of Herodotus and the rays of Kepler and Copernicus
remained sharp. These bouts of variation were 1-2min in duration. At
23:56UT when he checked again the periodic blurrings of the bands were
still present. The observer suspected atmospheric effects. M.Cook
(Frimley, UK) observed 22:00-22:30 and could see only 2 bands on the
west wall - but this may have been because of poor transparancy. The
ALPO/BAA weight=1.
In 1962 Sep 16 at UT08:05 Spirad (Victoria, B.C., Canada, 48"
reflector) obtained a spectrum with a UV emission, in H & K lines

London, UK, seeing III, but worsening (but not as bad as IV)
towards the end of the observing period, transparency 100%
clear, 22cm Newtonian reflector, x144, x185). The floor seemed
quite devoid of detail, apart from a vague mottling seen during
the briefest moments of best seeing conditions. At the start of
the observing period he could just glimpse the central craterlet
at x185, but could not be sure. ALPO/BAA weight=1.
On 1994 Apr 03 at 11:23UT D. Darling (Sun Praire, WI, USA) noticed that
Copernicus crater had a red spot on the west wall (found using Moon

same area?). NASA catalog weight=4 (high). NASA catalog ID #710.
On 1994 Jan 04 at UT21:00 J. Nibbering (Rosendaal, Netherlands)
obtained a photograph that shows a large crescent of light centred on
Tycho crater, but includes also: Lilius, but not to Clavius. Cameron
suspects strongly that it was caused by camera lens flare. The Cameron

On 2009 Jun 16 at UT 03:20-03:40 P. Morgan (UK, 30.5cm reflector, x400,
seeing=6/10 and transparency=5/5) observed a large diffuse ashen-like
effect over the shadow filled floor of Plato. The effect was lighter
towards the south. Observer checked the effect with both left and right
eyes and it remained the same. Unusually no shadow spires from rim
moutain peaks were seen. A check for colour in the region effected
revealed none. As time progressed, terrestrial twilight encroached. A
sketch was made. The ALPO/BAA weight=1.
On 1981 Oct 21 at UT 11:35-11:48 B. Hobdell (St Petersberg, FL, USA,
10" reflector) found that the south peak of Plato on floor glowed white
at 11:35UT, then a milky shade spread all aorind Plato's floor
(previously completely shadow filled). The needle like shadows started
to be indistiguishable through the sunlight (dawn on Earth). The cloud
like feature was washed out by daylight at 11:48UT and conformed to the
"white area except a tail that reached the cetre of Plato" Spurious
colour was not seen. The Cameron 2006 catalog ID=157 and weight=3.
On 1981 Oct 21 at UT13:40-13:45 D. Louderback (South Bend, WA, USA,
10" reflector) observed a cloud on the north east quadrant of
Aristarchus crater, and also covered the bright spot on the east wall
(Cameron says that the east wall bright spot is Bartlett's "EWBS".
Louderback mentions that this TLP gave Aristarchus a diamond ring
effect. The Cameron 2006 catalog ID=157 and weight=3. The ALPO/BAA

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

On 1871 Nov 20 at UT 17:30-19:30 H. Pratt (UK) saw one of the most
spectacular TLP obscurations that he had ever seen in Mare Frigoras. He
observed a kind of haze around the north west (NE?) slopes of Plato.
This effect was not seen elsewhere and all objects in Mare Frigoris
were indistinct or veiled. By 18:30 the effect was modified and by
19:30 very little trace was seen. Ref. from Corliss.

On 1985 Sep 28 UTC 20:54-23:52 P.W. Foley (Suffolk, UK) found (actually
before 20:54 UT) brightness variance in Torricelli B. J.D. Cook
(Frimley, UK) observed a brief blue coloured patch somewhere in the
Torricelli B region, but could not pin it down precisely. At 22:50UT
M.C. Cook (Frimley, UK, 30cm reflector, seeing III - occasionally V,
transparency moderate to good) Found the crater to have an elongated
appearance (in SSW-NNE direction) in white light, similar to the
previous night. A bright elongated spot was seen on the NNE floor,
close to where the wall should be. Not able to define the rim. There
was a very dark surrounding area to the crater, similar to what it was
on the previous night (roughly 1/4 brightness of Censorinus). 23:04UT
brighter in yellow, then red, then blue. At 23:10 it was seen that blue
filter dulled the crater - this was odd because both Censorinus and
Proclus were brighter in blue, which is what he would normally expect.
At23:15 UT Censorinus was brighter in blue, then yellow then red
filters and some orange spurious colour seen to the south of
Censorinus. At 23:23UT no spurious colour seen on Proclus or
Censorinus. 23:46UT Torricelli B elongated as before, but a very faint
ray might have been seen to the south west of the rim. This report is
not in the 2006 Cameron catalog. The ALPO/BAA weight=3.

The Cameron catalog ID=283 and the weight=3. The ALPO/BAA
weight=1.
Messier A 1951 Aug 20 UT 01:48-03:00 Observed by P.Moore
(England, 8.5" reflector, x350). Bright cloud like circular
patch seen on S wall of Messier A. It was the brightest object
in the vicinity. Observations ceased due to the Moon setting
behind a tree. W.Haas thinks that this effect is not unusual at
similar colongitudes. Moore checked again under similar
illumination and still considers the Aug 20 appearance abnormal.
NASA weight=4. NASA catalog ID #545. ALPO/BAA weight=2.
On 1993 Dec 31 at UT 05:00-07:40 S. Beaumont (Cambridge, UK, 12"
reflector) "saw a patch of hazy light to NW (from c.p. alpha) at 0550
craters B & J shadow of alpha had not reached E wall yet, but at 0536
it did. Alpha > at 0550. Craters B & J to SE had faded, vanished at
0630. Hazy patch remained around peak, alpha low mainly to NE like a
comet's tail. Slightly reddish fringe to E wall. (shown in sketch)".
The above has been quoted in full from the Cmeron catalog because the
catalog desription is slightly ambiguous and any attempted summary
might make the description more unreliable. The cameron 2006 catalog
ID=470 and the weight=3. The ALPO/BAA weight=2.
