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.
Plato 1877 Jul 29 UTC 02:00?-02:30 Observed by Gray (England?) "S. of
crater a bright streak that disappeared at 0230" NASA catalog weight=3
(average). NASA catalog ID #196.
In 1937 Apr 29 at UT 09:30 Firsoff (Glastonbury, UK, 6" reflector and
filters) observed a slight greenish colour (Cameron says colour of
ground? no TLP?). The Cameron 1978 catalog ID=420 and Weight=4. The
ALPO/BAA weight=3.
Macrobius 1898 Dec 31 UTC 20:00 Observed by Goodacre (Crouch End,
England, 12" reflector) "Interior nearly filled with shadow at sunset.
Inner E.wall very bright-a distinct penumbral fringe to black shad.
cast on it from W.wall. Seen best using high powers. (Firsoff & MBMW

1999 Jan 07 UT 01:57 C. Brook (Plymouth UK, 65mm refractor,
x125, seeing good) found this mountain unusually dull. In
contrast, Mons Pico, Montes Teneriffe, Montes Spitzenberg,
were all normal. ALPO/BAA weight=1.
Triensecker Rille 1915 Jul 03 UTC 00:00? Observed by Markov (Russia)
"Several spots changed their shapes compared with Gordeenko's depiction
on 5/23/12 see #339; which cannot be explained by light variations."
NASA catalog weight=3. NASA catalog ID #356.
Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK,
10.25" reflector, x250, Wratten 44a and 25, seeing II) noted
that Aristarchus was surrounded by a dark area in the blue
filter. They did not regard this as a TLP at the time. However
because Aristarchus is surrounded by blue material in real life,
this should have been brighter? For this reason, despite the
observer regarding this as a negative TLP, an ALPO/BAA weight=1
has been applied.
On 1977 Nov 03 at 22:13UT P.W. Foley (Kent, UK, 11" reflector, x285)saw
some flickering in Gassendi (Clouds on limb - according to Csmeron?).

saw a small circular area of grey or white in the dark south end
of Copernicus.The area showed up better through a Wratten 15
yellow filter, but was not seen at all through a purple Wratten
35 filter. P.W. Foley (Kent, UK), confirmed this but thinks that
it is normal. Cameron 2006 catalog ID=68 and weight=1. ALPO/BAA
weight=1.
Copernicus 1979 Sep 15 UT04:40-05:25 J.Saxton (Leeds, UK,
8.5" reflector, x185, seeing I-IV, worsening towards local
sunrise) made a sketch and noted that the northern tip of the
internal shadow, by the floor, was not completely dark. The edge
of the floor here could be distingished, even though it was in
shadow. ALPO/BAA weight=1.

On 1964 Dec 19 at UT 03:28-04:28 Sunduleak and Stock (Cerro-Tololo,
Chile, 16" reflector) using photoelectric photometry during a lunar
eclipse, observed on the northern edge of Mare Numbium, and south of
Copernicus (20W, 0N), a strong anomalous enhancement of radiation
(confirmation according to Cameron). On 1964 Dec 19 at UT 02:35 S.J.
Hill et al (Kitt Peak??) observed during a lunar eclipse an anomolous
bright area (location not given). Cameron says that this is an
independent confirmation of Sanduleak and Stock's TLP report. The
Cameron 1978 catalog ID=868 and 569 and weight=5. The ALPO/BAA
weight=4.
On 1982 Dec 30 at UT10:09-10:58 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x342, S=9/10) found that when the umbra of the eclipse
shadow transitted across Aristrachus, the crater was a bright blue -
this effect lasted until 10:14UT. Flashes/flickers (~0.1 sec duration)
were seen at 10:15UT. He saw another flash at 10:24UT. Another
observer, Harris (Sun Praire, WI, USA, 6" reflector, S=9/10) saw

On 1975 Nov 18 at UT 19:38-23:34 Moore (Johannesburg, South Africa, 2"
refractor, S=II), Peters (Kent, UK, 8.5" reflector, x120, S=IV), Good
(Guilford, UK, binoculars), Foley (Dartford, Kent, UK, 12" reflector
and photographs), and McKay (Kingston, England, UK, 6" reflector, x48)
observed the following in Aristarchus during a lunar eclipse: "It
appeared much fainter than ever before seen in ecl. by Moore. Fainter
than Proc., Cop., & Tycho. Others rated brightness in order-- Hell,
Stevinus, Furnerius, proc.; & Proc., Tycho, Hell, Aris. Photos
confirmed dimness of it. For some observers it became invis. at S=II
(good). Good ranked at least 4 other craters brighter than Aris. & that
at 2035h it dimmed. Earthshine cond. extraordinarily good. Peters, at
S=IV (fair?) rated Aris. brightest". At 23:50UT LeCroy Jr and Sr
(Springfield, VA, 4.5" reflector, S=7) observed four glowing spots on
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
provided. Cameron comments that the colours fit Fitton's predictions on
spectral dispersion in our atmosphere from atmospheric inversions. The
brightness measued was 10+ and normal should be 9, and the plain is
4.5. The Moon's altitude at the LeCroy site was 45 deg. The Cameron
1978 catalog ID=1418-1420 and weight=5 (1-0 for LeCroy report). The

gradual fade over the Moon as the eclipse progressed, there was a 2"%
rise in brightness of Aristarchus.Graphs were submitted and photos.
A.C. Cook supplied CCD images and CCD photometry. A photograph by
Conway (Sun Prarie, WI, USA) at the start of the eclipse reveal a
bright colourless spot (aparently confirmed). The Cameron 2006 catalog

On 1963 Jul 06 at UT 21:00 (estimated) Chernov (Russia) observed that
the dark spot in Riccioli size increased suddenly during a lunar
eclipse as it entered the shadow, before merging with the shadow. The

weight=1. The ALPO/BAA weight=1.
On 1906 Feb 08 after a lunar eclipse, Frost and Stebbins determined
that Linne had enlarged by 1" in size.
On 1985 May 05 at UT23:25-23:58 UT P. Moore (Selsey, UK) observed a
yellow tinge on the southern wall of Aristarchus - this was odd because
no colour was seen elsewhere on the Moon. The Cameron 2006 catalog ID=
271 and weight=3. The ALPO/BAA weight=3.
On 1956 Nov 19 at UT 00:00? an unknown observer (Cameron gives an AGU

On 1990 Aug 08 at OT 07:47-09:00 UT D. Louderback (South Bend, WA, USA,
3" refractor, x173) "(SS) Piton's all pts were << but nearby plain was
normal. Ridges at 5.3 at B, C, D but 3 alb at B, C, D (norm = 7) but
bearby plain was normal. At A 3, was hazy but ill defined. Parts of mt
brightened but others didn't. Times between brightening were 6-8s.
Similar to seeing fluctuations. In red mt stayed dull & steady. In blue
it blinked." - this is a direct quote from the Cameron 2006 catalog
because it is very difficult to summarize. Louderback comments that the
TLP was still going on at 09:00UT. The Cameron 2006 catalog ID=406 and
the weight=4. The ALPO/BAA weight=3.

On 1984 Nov 10 at UT19:15-19:50 R. Moseley (Coventry, UK, the Moon's
altitude was low) noticed that the region from the central peak and
over and onto the east wall looked unusual. 8 bands were visible, "two
on E. wall of c.p. strongest, surrounding collar grey increasing
intensely outward. Band at 2 o'clock position was very dark. Bright
spot on W. wall at 4 o'clock position." A sketch was made that

Aristarchus crater looked dimmer than normal. The ALPO/BAA weight=1.
On 1895 Sep 07 an unknown observer (Lewis Swift?) observed a pale blue
segment on the upper limb - this was apparently confirmed by Faulkes
(Mem. BAA, 1895). Cameron says that this is probably 1895 Sep 08 at UT
06:00 as Sep 07 is local time. She also infers that "upper limb" is the
southern limb and that Swift was at the Lowell Observatory, Flagstaff,
AZ, USA. The Cameron 1978 catalog ID=285 and weight=5. The ALPO/BAA
weight=2.
On 1983 May 31 at UT03:45-04:30 K. Marshall (Medellin, Columbia) noted
