On 1971 Feb 27 at UT 23:50-00:00 Dezmelyk (Newtown Square,
Pennsylvania, 2" refractor, x225, x500, seeing=good) observed in
Earthshine a peculiar white glow too far from the terminator to be
sunlit. 9 minutes later they could not detect this, nor any other
spots. The spot concerned was about 8-9th magnitude - "like galaxies".
They checked the lens for dirt but it was clean. A drawing was
provided. The Cameron 1978 catalog ID=1285 and weight=2. The ALPO/BAA
weight=2.
In 1837 Mar 19 at UT 18:00 Rankin and Chevalier (France) noted a
singular appearance on the dark side. Luminous spots there & general
glow on upper (S?) limb. Whole shaded part seemed to be a mixture of
light & shades. The Cameron 1978 catalog ID=124 and weight=5. The
ALPO/BAA weight=3.
On 1950 Apr 21 at UT 03:30 Barcroft (Madera, CA, USA, 10"
reflector x74 & x98) observed that Aristarchus glowed in
Earthshine. However Earthshine visibility was exceptionally goo.
The Cameron 1978 catalog ID=525 and weight=3. The ALPO/BAA
weight=1.
On 1979 Sep 25 at UT00:40-00:51 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x62) found the crater to blow and fluctuate between
magnitude approximately 4 and 5. Initially it was bright, then faded,
then brightened again aggroximately x2 and then faded into the
background. The Cameron 2006 catalog ID=70 and weight=0. The ALPO/BAA
weight=1.
Mare Crisium 1998 Jan 31 UT 17:15-17:35 R. Braga (Corsica
(MI), Italy, 102mm f8.8 refractor, x180, with no diagonal,
seeing II, Transparency poor). A very bright point located at
23N 54.5E this was normal! - what was unusual was that it
vanished when viewed through a blue Wratten 38A filter (this
filter absorbs red, UV, and some green light). The ALPO/BAA
weight=2.
Aristarchus 1949 May 01 at UT 20:45 H.P. Wilkins (Kent, UK, 3"
refractor x100) observed Earthshine was very detailed and
Aristarchus was noticeably a bright patch. Upon concentrating on
Aristarchus, he observed that it flared up in brightness
considerably more still for about 2 sec. During this flare up
time, inner terraces and the central peak became visible.
Cameron says that this was confirmed by Barcroft a few hours
later???? The Cameron 1978 catalog ID=518 and Weight=5. The
ALPO/BAA weight=3.
On 1903 Mar 03 at UT 20:00 Gheury (London, UK) observed a star-like
point in the dark side in Sharp(?) "Gray-blue marbling, glimmering,
intermittent. (indep. confrm. of Rey?)". The Cameron 1978 catalog ID=
316 and the weight=5. The ALPO/BAA weight=4.
On 1988 Mar 23 at UT 01:15-01:30 M. Wisniewski (Chicago, IL, USA, S=F)
observed that Aristarchus was the brightest (mag 5), and only feature
visible in Earthshine. It had the appearance of a steady blue-white
star like point. Darling (Sun Praire, WI, USA) though observed other
features as well: Proclus, Theophilus, Cyrillus and Censorinus - all of
which were normal. The cameron 2006 catalog ID=319 and the weight=0.
The ALPO/BAA weight-1.
Sirsalis 1990 Mar 01 UT18:30-19:45 M. Holmes (Rochdale, UK,
21.5cm Newtonian, seeing Antoniadi I/II, Transparency very
good) was observing in earthine and saw an intense blue spot
"wink on" near to Sirsalis (sketch shows location on SE rim),
until clouded out at 18:30. When the sky cleared at 19:15UT
the spot was still visible but fainter, with a halo, the size
of Sirsalis A. By 19:35 there was a loss of detail, region
only a faint patch of light covering area twice the size of
Sirsalis crater. Clouded out permanently at 19:45UT. Cameron
2006 catalog event #392, weight=0. ALPO/BAA weight=3.
In 1900 Nov 26 at UT 19:00? an unknown observer (in Europe) observed a
suspicious obscuring phenom on a dark plain (mare). The cameron 1978
catalog ID=307 and the weight=2. The ALPO/BAA weight=1.
1951 Mar 13 UT 01:35:50 L.T.Johnson (USA) observed a faint flash
near W limb in earthshine - just S of Grimaldi.
ALPO/BAA weight=1.
On 1970 apr 11 atUT 05:29 Lucas (San Diego, CA, USA, 10" refelctor,
seeing=fair) and others (Oregon, USA) obtained a photometric record of
light level changes in Grimaldi crater. Visible reports by others
during the same time. The photometer paper chart pen moved off scale on
a 10mV scale adjusted to 1000mV. The peaks correlate with the visible
observers from California and Oregon. Bright flashes, 3-5 events
(confirmation during the Apollo 13 watch). The Cameron 1978 catalog ID=
1237 and weight=5. The ALPO/BAA weight=4.
A German observer by the pseudonym of "R" on 1883 Nov 05 UT 18:00 saw
Aristarchus as a vry bright 7-8th magnitude star in the dark part of
the Moon. The Cameron 1978 catalog assigns this event an ID of 240 and
a weight of 3. The ALPO/BAA weight is 1.

reflector, x178, seeing=good and steady) noticed a yellow-orange glow
in Gassendi (from a small illumnated crater?) in Earthshine at 19:35UT
and by 19:40UT it had become very bright white, afterwhich it
completely faded within 10 minutes. The Cameron 2006 catalog ID=393 and
the weight=1. The ALPO/BAA weight=3.

catalog weight=2 (low). NASA catalog ID #463.
On 1993 Dec 19 at UT 16:00-17:00 S. Beaumont (Cambridge, UK, 12"
reflector, x230) observed in Theophilus that the "c.p. > reddish brown
tint to SW (on peak?)" but suspected that it was probably spurious
colour, however no colour was seen later. The ALPO/BAA catalog ID=469
and the weight=3. The ALPO/BAA weight=2.
On 1979 Mar 04 at UT18:15-21:45 P.W. Foley, (Kent, UK, 12" reflector,
x180, seeing II-I) noticed that Aristarchus was unusually bright
(though colourless) - the northern part being the more brilliant. Other
features seen but less visible, though still quite obvious. A CED
brightness reading of 0.3 was recorded - the highest ever so far. Amery
(Reading, UK, 19?" reflector, 50-100x, obtained photographs. The
Cameron 2006 catalog ID=46 and weight=5. The ALPO/BAA weight=2.
On 1979 Mar 04 at UT18:15-21:45 P.W. Foley, (Kent, UK, 12" reflector,
x180, seeing II-I) noticed that although other features in Earthshine
were quite obvious, Grimaldi was not, though at x200 (should this be
20:00?) Grimaldi "shone with a brilliance to that of a thin cresecent
of 2-3d". Amery (Reading, UK, 19?" reflector, 50-100x, obtained
photographs. The Cameron 2006 catalog ID=46 and weight=5. The ALPO/BAA

On 1982 Jul 27 at UT 20:04 P. Madej (Newsome, Huddersfield, UK, 16cm
reflector, x33, seeing I to II, transparency fair, Hoya linear type
polarizer filter) observed that when the filter was used on Mare
Crisium, that the north part became a bright gray when turned to 45deg,
but when turned the other way it returned to normal. The ALPO/BAA
weight=3.
On 1964 Jun 17 at UT 04:15-05:01 Cross et al. (Whittier, CA, USA, 19" ?
reflector, S=7-8) observed near Ross D: "Gas cloud. Motion". The
Cameron 1978 catalog ID=818 and weight=4. The ALPO/BAA weight=4.
Large plume-like diffuse cloud over central peak, very
large compared to central peak (@ approx 30km diameter)
with intensity much different from other parts. Brightness
between walls and shadowed floor. Would take 3 minutes to
collapse, so continuously fed. 13-14 days later, at SS,
central peak was normal. Kuiper took photos after Kozyrev's
observations, but saw nothing abnormal. Drawing. Haas saw
nothing in 12inch reflector at the time. Cameron 1978

On 1985 Oct 11 at UT 04:56-05:12 D. Louderback (South Bend, WA, USA,
4" refractor, x95, seeing=1-2-1 and transparency=4) detected a change
in brightness of Mons Piton point D (his designation) during 04:56-
04:59. The whole of the east slope was affected - initially bright and
then faded and there was a blue colour (detected with filters). The
variabilty was 8-11sec (Cameron suspects atmosphere as the altitude was
low). The brightness stabilized at 05:12UT, but variability resumed
until observing finished. As a comparison Aristillus was not seen to
change. The Cameron 2006 catalog ID=287 and the weight=1. The ALPO/BAA
weight=1.
Alphonsus 1966 May 27 UT 21:10 Observed by Sartory, Moore,
Mosely (England and Ireland, 8.5" reflector, 10" refractor) "Red
colour on central peak area" NASA catalog ID 937. NASA catalog

On 1994 Apr 19 at UT 00:00 P. Kursewicz (Epping, NH, USA) observed a
dark patch surrounding Picard crater. The ALPO/BAA weight=1.
On 1982 Jul 28 at UT20:38-20:48UT A.C. Cook (Frimley, Surrey, UK, 12"
reflector, seeing IV-V, some spurious colour prsent) observed that the
central peak of Alphonsus was brighter in red light than in blue, so
much so that at the start of the session the peak could hardly be seen
in blue light. The central peak varied in brightness in red light but
not in white light. The central peak of arzachel was brighter than that
of Alphonsus in white light but had no colour - Arzachel's central peak
did however appear to fade in brightness over time (or was it Alphonsus
getting brighter?). Cameron 2006 catalog ID=177 and weight=3. The
ALPO/BAA weight=2.
Plato 1918 May 20 UT 18:00? Observed by Markov (Russia) "Brightness in
shadow of the light sector & 1 spot" NASA catalog weight=3 (average).

On 1965 Jul 08 at 01:00?UT a white streak was seen in Grimaldi,
extended towards the limb. This was observed by Rubens de
Azevedo, et. al., Brazil. The Cameron 1978 catalog ID=884 and
weight=3. ALPO/BAA weight=2.
On 1975 May 18 at UT2115-2145 C. Lord (St Annes-on-sea,
Lancashire, UK, 76mm f/16 refractor, x170, Wratten 25, and 44a
Moon blink filters used, Transparency 4.5/5, no wind, S=F). The
west flank of Maginus, and the interior, appeared to be partly
obscured. No other features in a similar position along the
terminator were obscured. No colour blink was detected with the
filters, though a pronounced red/white light blink was noted; the
device employed a N.D. x4 filter. By 21:45UT the floor was no
longer obscured and only Magninus G was masked in a white haze;
however immediately adjacent to the terminator was an ill defined
misty patch lying where the outer flank of maginus would have
been visible. The rest of the terminator was sharp. The
obscuration was only seen to advantage in blue and int. light,
and the blue/int blink was only very slight. Findlay and
McDonnell observed 21:30-23:00 using a 25cm refractor (Seeing II-
III) but failed to see anything unsual. NASA catalog weight=3.

Plato 1982 Nov 24 UT 22:00-23:30. K.P. MArshall (Columbia, 12"
reflector, x100, x200, x480, seeing III, reasonably steady, but
some turbulence. No craters could be seen on Plato's floor,
despite observing conditions being acceptable. The floor was
evenly toned, and the walls were sharply defined. By 23:10 there
was a suspicion that the central craterlet was there, but he
could not quite make it out, even with averted vision. ALPO/BAA

weight=1.
On 1992 Jun 09 at UT 18:52 G. Kolovos, Thessaloniki, 40.63111N,
22.9597W, height 28m, Greece) photographed two blue spots on the

Plato 1976 Nov 30 UT 19:15 T. Flynn (Edinburgh, UK, 29cm
reflector, Wratten 25 and 44a filters) observed that there
were two whitish semi-circular tide like marks enclosing two
dark patches adjoining the interior west wall The observer was
puzzled because if these were two masses of spawning foot
hills, then why would the cental areas, presumably the higher
parts, be dark - when the contrary is usually the case?
ALPO.BAA weight=1.
Copernicus 1976 Nov 30 UT 19:40 T. Flynn (Edinburgh, UK, 29cm

In 1962 Sep 09 at UT 01:42-02:00 Bartlett (Baltimore, MD, USA,
5" reflector, x180, S=5-4, T=3) observed in Agrippa the shadow
of the central peak to be grayish, not much darker than the
floor, estimated at 3deg bright, whereas on 1962 Jul 12, at col

On 1974 Jan 03 at UT 18:30 a Norwegian amateur astronomer,
Hoydalsvik (Hakonsgate, in West Norway, 60mm refractor)
photographed the Moon using High Speed Ektacrome (400ASA) film
with good focus. The TLP was located on the southern slope of
Sasserides H and was pink in colour with some bluish in it.
The coloured area was circular with a diameter of 0.5 minutes
of arc. Only one exposure was taken. The photograph was
checked by the Institute of Theoretical Astrophysics,
University of Oslo. Although they thought it was probably
genuine (could have been an impact flash?) suggestions by the
BAA lunar section favoured static electrical discharge on the
film. It is uncertain whether the film was ever examined by a
Photographic developing lab such as Kodak, who would be able
to tell if it was real or an artefact. ALPO/BAA weight=1.
Tycho 1998 Feb 06 UT 22:48-22:54 R. Braga (Corsica (MI),
Italy, 102mm f8.8 refractor, x180, with diagonal, Wratten 23A,

Om 1987 Sep 04 at UT 03:00 J. Caruso (Middletown, CT, USA, 3"
refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not
visible, however Heraclides E, Helicon G, and indeed many other smaller
craters could be seen. There were two small mountains in the general
area of Bianchini G. and a mare ridge - all these were clearly seen.
Caruso states that Bianchini G should normally be much more clearly
seen than the other features mentioned and is the same size as
Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3. The

On 1955 Jan 05 at 01:00-01:30 UT D.A. Logue (Larchment, PA,
USA, 15cm reflector at x340, seeing Good) saw a strange blue
light above the surface of the Moon where the night and the
day meet. He observed this light for more than 30 min and it
did not appear to move. It appeared like a star in that the
rays of light came from it. The observer adds that he first
thought thst the objects was a star, but later decided that it
had to be on the Moon itself. A drawing shows the blue spot
near the rugged south west (IAU?) limb of the Moon. The editor
of the Strolling Astronomer (Vol 8, No. 11-12, Nov-Dec 1954,
p146) was unable to identify the craters drawn. The editor
speculates that the observer saw a high mountain peak with its
summit in sunlight and detached from the illuminated regions -
however this would not explain the blue colour. Note this is
an ALPO observation and does not apear in the Cameron
catalogs. ALPO/BAA weight=2.
On 1982 Aug 01 at 00:00-01:00 K. Marshall (Medellin, Columbia, 12"
reflector, seeing I-II) noted shading on the east floor of Plato that

both low and high magnifications. Foley notes that this was unusual.
There were three craterlets visible on the floor - the central one was
the brightest. Cameron 1978 catalog ID=178 and weight=3. ALPO/BAA

A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and
definition fairly good. Observer noticed that the Mare seemed covered
with a close network of innumerable streaks, and spotted with countless
numbers of light specks, so that it would hardly be possible to
delineate them all in one night. The spots and streaks together must
have numbered ~1000. The observer had never seen anything like the
number of spots and streaks. Peirce A, was not at all easy to see and
neighboring spots almost as bright made it difficult to distinguish
which one was Peirce A. ALPO/BAA weight=3.

Argentina, 105 mm Maksutov-Cassegrain, x154, seeing 6/10, some
interuption from clouds) observed a light spot SE of the
centre of the floor of the crater, which came and went in
visibility. There is a light spot here, but what was unusual
was that the visibility decreased over time.

On 1997 Oct 13 at UT11:09-11:21 D. Rodway (Oamaru, South Island, New
Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in
the south east corner interior of the crater Aristarchus. This colour
was confirmed by the observers wife. By 11:21 UT the colour had faded
completely. Rodway had been a lunar observer since 1958, using a wide
range of instruments from 3 inch refractors to 12 inch reflectors and
had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so
was an experienced observer. The ALPO/BAA weight=4.
On 1963 Nov 28 at UT 05:00-06:00 Greenacre, Barr, Hall and
Dungan (Flagstaff, AZ, USA, 24" refractor) observed a deep violet
area form on the western exterior of Aristarchus, and a less deep
violet area form to the eastern edge of Aristarchus. As these
were becoming stronger, a blue-like haze formed on the sunlit
floor of Aristarchus, that obscured underlying detail. The
ALPO/BAA weight=2.
On 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector,

Proclus 1990 Mar 09 UT 00:12-00:13 Observed by Marie Cook (Frimley, UK,
3.5" Questar telescope) observed a "long plume of light" the brightness
was the same as the wall region. It went from the southern rim about
half of the way across to the centre in the "northerly". The plume
feature was not seen at higher magnifications. Change in brightness
also noted. The Cameron 2006 catalog ID=394 and the weight=1. The

On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit
around the Moon, obtained images of the Cobra Head region of
Aristarchus crater that suggested a ~15x colour ratio increase (0.4
microns / 1.0 microns) in comparison with images obtained on 1994 Mar
03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting.
However it was later suggested that this was due to incorrect
radimetric calibration procedures being followed. The ALPO/BAA

Aristarchus 2015 Mar 03 UT 23:58 Brendan Shaw (UK) saw a flash
on the NW rim of Aristarchus on his computer screen - the camera
was working in the near IR. Seeing was not very good at the

reflector, x200, Wratten 25 and 44A filters, seeing II-III,
transparency, good) noticed in Aristarchus, blue to the north west
(IAU?) internal wall, also blue observed in other small bright objects
against dark backgrounds. Lunar rotational axis and optical normal
related such that the normal runs NW-SE (IAU?) through these features.
Observer deduced that the coliur was obviously spurious and no blink
was seen in any feature. The blue disappeared as the lunar altitude
increased and no blue seen by 00:00UT. This is a BAA lunar section

reflector) Taruntius faded from Vmag-3.21 to 4.04, a 0.82 difference in
magnitude in 2.5 hours - a photometric measurement. The average
magnitude for this age is 4.03, so therefore the crater had brightened
by two times above normal. The Cameron 1978 catalogID=769 and the

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.
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 1962 Sep 16 at UT08:05 Spirad (Victoria, B.C., Canada, 48"

12.5"reflector, seeing=7/10 and T=3) did not detect the dark region on
the south east floor of Proclus (the TLP from a few days earlier), but
did see 2 "linear mounds". The Cameron 2006 catalog ID=335 and the

On 2011 Jan 21 at 22:30UT N.Longshaw (UK, 4" Achromatic
refractor, x128 & x160, Seeing III, transparancy average)
suspected on the eastern edge of Geminus, on the border of the
crater filled shadow and the eastern illuminated rim, a
brownish, almost speia hue. This extended for a short distance
from the floor shadow into the illuminated rim width and spanned
from the north to the south of the crater. For a comparison,
Cleomedes was checked but nothing unusual was noticed in its
shadow. The observer notes that Elger also saw a warm brown or
sepia tone. ALPO/BAA weight=1.
On 2013 Dec 19 N. Longshaw (Oldham, UK, Seeing III, TAK FS 78
APO Refracror) observed a diffuse area east of the central

On 1958 Nov 01 at UT 00:00 a TLP was seen on the Moon (location and
observer not given). The Reference for this is Palm, 1967. The Cameron
1978 catalog ID=702 and weight=0. The ALPO/BAA weight=1.
On 1964 Jun 30 at UT 05:50-06:10 Bartlett (Baltimore, MD, USA) observed
the following in Aristarchus: "Nimbus only -- dark viol. hue. S. part
of Aris. floor was granualated & a brown tinge -- changed to yellow & a
brown tinge at 0500. First time he ever saw such a change in color.
(this obs.listed in 210 & MBMW as June 20, but is a misprint)". The
Cameron 1978 catalog ID=828 and weight=4. The ALPO/BAA weight=3.
Aristarchus 1976 Nov 13 UT 05:25 Observed by Bartlett (Baltimore, MD,
USA, 3" refractor, 54-200x, S=6, T=4) "Floor 8deg except S.=6deg which
is also granulated & la pale yellow. Different aspect fr. other obs. at
same col. Viol. in outer nimbus. Bright blue-viol. glare where viol.
radiance was on 11th. SWBS still large & 9 deg bright." NASA catalog
weight=4 (high). NASA catalog ID #1457.
Alphonsus 1958 Nov 03 UT 02:30-03:30 Observed by Kozyrev,
Ezerski (Pulkova Observatory, Crimea, Ukraine, 50" reflector,

Aristarchus 1976 Nov 14 UT 06:09 Observed by Bartlett (Baltimore, MD,
USA, 3" refractor, 54-200x, S=5-4, T=5) "Walls & floor 8deg except S.=
6deg, SWBS now smaller but still 9deg. S.floor still granulated & now
yellow-brown. Strong viol. tint still on outer nimbus but now viol.

On 1988 Apr 19 at UT 01:15-04:00 J. Horne (Steadman, NC, USA, 8"
reflector, S=4/10) took photographs of the Moon's Earthshine (appeared
in the Aug 1988 Sky and telescope magazine). Aristarchus was bright. In
addition several members of the Madison Astronomical Society also found
the crater to be bright and one of them saw streaks and flashes from
the crater. Manske (8" reflector, x97, + binoculars, S=E) found the
crater to be "abnornormally bright" where as other craters in
Earthshine were just normal. Fryback's (Madison, WI, USA, 8" reflector,
S=VG) photographs confirm that the crater was very bright - the Moon
was only 4deg in altitude though. The Camweron 2006 catalog ID=325 and
the weight="confirmed". the ALPO/BAA weight=3.
