reflector, x375) and Emanuel (West Covina, CA, USA, 4.5" reflector)
observed 4th magnitude star-like flashes to blotches in Aristarchus, in
ashen light. Cameron says that this is independent confirmation and
also that the date in MBMW is 7/1/65 which is local time + 2nd UT. The

On 1988 Apr 21 at UT 01:28-04:00 D. Fryback (Madison, WI, USA) took a
series of photographs - Aristarchus was a luminous patch and in one
photograph a red spot (Cameron suspects marks on the film). is seen
near Aristarchus. Strangely though when looking through the telescope,
the crater was not excessively bright. D. Spain (Fairdale, KY, USA,
3.5" reflector?, x60) observed a narrow white streak of mag 5-6 of
duration 0.5 sec that covered 160-320km near the centre of the Moon at
01:53UT. A similar streak happened but the direction was different.
Next 2 small red flashes were seen at 02:00 and 02:01UT of magnitude 7
(<1sec) in the vicinity of Aristarchus. The cameron 2006 catalog ID=327

On 1968 May 02 at UT 01:20-02:14 Doughty (Red Bank, New Jersey, USA,
8" reflector, x120) observed a bright area in Aristarchus, surrounded
by a faint glow. May have been atmospheric dispersion. Glow fainter at
01:56UT and imperceptible at 02:14UT. Kelsey and Ricker consider the
observation abnormal. The Cameron 1978 catalog ID=1070 and weight=3.

On 2012 May 25 UT 05:35 Brenner F crater was recorded in a larger
area image by M. Collins (Palmerstone North, New Zealand, ETX-90
with LPI imager (monochrome mode) - seeing not good). He took a
sequence of 108 images from 05:35-05:40UT, and in the 65th frame,
a light spot, approximately 4 pixels wide can be seen just
outside the western illuminated rim of Brenner F. It is not
visible in any other frames. The exposure time was 0.125 Sec.
Because the western edge of the spot is very sharp, and the rest
of the Moon is slightly blurred due to seeing, it is thought that
this was most likely a cosmic ray event in the CCD camera - the 4
pixel width was perhaps contributed to by the image compression.
It could also be some bright surface spot that was made invisible
most of the time by poor seeing, and then during a brief period
the atmosphere is sharp enough at that locality to make it
visible. ALPO/BAA weight=1.
On 1985 May 24 at UT 21:01-22:40 P.W. Foley (Kent, UK, 12" reflector)
observed that Aristarchus was very bright (varied) and had a strong
(transient) red/rose colour and the crater floor was glowing. Detail
was visible. Mobberley (Suffolk, UK) also found the floor of the crater
to be "glowing". Photographs of Earthshine excellent. The Cameron 2006
catalog ID=274 and the weight=5. The ALPO/BAA weight=3.

On 1975 Dec 08 at UT18:00-20:40 P.W. Foley (Wilmington, Kent,
UK, 12" reflector, x60-x624, seeing II, slight mist) found
Aristarchus to be less well visible than features such as:
Grimaldi, Reiner, Darwin/Byrgius, Kepler, Plato and Sinus
Iridum. Earthshine was exceptionally good tonight and was
orange/red in colour. Photographs were taken and these confirmed
the apparent dullness of Aristarchus. ALPO/BAA weight=2.

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 1975 Apr 19 UT 21:09 P. Foley (Kent, UK), detected blue in
Plato on east. Fiton at UT20:45 found blue along the south wall
at the east (IAU?) end, which was very bright white. Blueness
extended towards the large landslip at the east of the formation.
Immediately north of the landslip, where the bright wall curves
first westwards, then again northwards, red could be faintly
detected, folloowed by a very faint blue. All other parts of the
formation were normal. Examination with a Moon blink device
revealed no colour blink. J-H Robinson also found blue, with red
on the west wall (exterior?). By 21:30UT Fitton found Plato to be
normal and so was Proclus, though he did find Epigenes (bright
cresecent of east wall only) slightly blue to the N.W and red
to the S.E. Mare Crisium was normal. Prominent spurious colour
seen on Venus, but it was low in the sky, with blue to the north
and red to the south. However J.H. Reading, managed to see the
north east floor blurred and slightly blue from 22:45-23:00UT.

90mm Quastar Cat., Seeing III, transoparency hazy) and by Moore
(Selsey, England) "Following an alert call by Miles concerning the
crater Proclus looking different, Cook observed a circular dark patch
that filled about half of the eastern half of the crater floor. To cut
down the glare a blue filter was then used and a slightly less dark
area was seen extending from this in a southerly direction. 8 rays were
seen. The dark patch was confirmed by Patrick Moore. However David
Darling (USA) who observed a few hours later on 1989 Jul 14 at 03:28 UT

On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector,
seeing II-III) noted that the south wall of Plato at the 11 o'clock
position, at the location of a cleft, was fuzzy on either side of the
cleft. There was also a deep red colour along the cleft and the outside
wall. The colour had gone by 22:40 though. All other parts of the rim
of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III)
sketched some obscurations at 22:03UT. At 22:08UT the red colour
reduced to a red line and vanished by 22:37. The south wall obscuration
varied in size and there was a possible obscuration at the 7 o'clock
position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and
M.Cook's observations. Detail inside the crater was sharp, but colour
oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km
away had atmospheric ripples affecting his observations. At 21:36UT G.
North described the south wall as odd in appearance and the terrain
south of this was lacking in detail - this was odd because elsewhere
Plato was nice and sharp. At 21:45UT though the north section of the
crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5.

"A blue/violet streak, lasting ~10 minutes was seen on the floor of
Sinus Iridum between crater Bianchini and Promontorium Heraclides. The
suspect TLP mybe an effect of instrumental achromatic aberration, but
there is the small possibility that the effect was real." A UAI
observational report. The ALPO/BAA weight=1.
On 1989 Jul 14 at UT 03:28 D. Darling (Sun Praire, WI, USA) found a

On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector)
and at the same time Doherty (Sussex, UK, 15" reflector) observed a
strangely bright and pink/red north rim of Aristarchus crater during
UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT.
M.C. Cook (Frimley, UK) found the northern wall to have a red/purple
colour but the effect vanished after 50 minutes. Cook also saw a "V"-
like notch in the NW crater shadow and this appeared to be bigger than
normal. G. North (Sussex, UK) saw a tinge of pink colour on the
northern rim and a bit later a "ruby red" colour on the north-west wall
- again this effect lasted 50 minutes. Moseley verified the colour.
Finally M. Hather (Yorkshire, UK) suspected the north wall of
Aristarchus to be blue in colour. Cameron suspects that this TLP is not
spurious colour because it is in the wrong place. The Cameron 2006
catalog ID=276 and the weight=5. The ALPO/BAA weight=4.

10" f/4 reflector, x200, seeing 6, Transparency 3 - scattered
cirrus) observed visually (depicted in sketch) the two closely
spaced NW wall dark bands) to have a rusty-red hue. The colour
of these bands did not change over the period of the observing
session. Images were taken, but resolution and image S/N is
not sufficient to resolve separate bands here, or to detect
colour. The ALPO/BAA weight=1.
On 1981 Aug 11 at UT21:05-21:36 G. North (England, seeing=poor)

FL, USA - ALPO. 8” SCT via a 9mm ortho eyepiece. Transparency
magnitude 3 and seeing was 7/10) checked the crater without
filters as well as comparing with W25 red and W44A blue
filters using 226x. He saw no color on the SW part of the
crater floor or on the NW wall. Using the filters, however,
he did note that the high peak on the S wall was brighter in
blue than red. He tried this filter blink a number of times
because he had never seen this before in Gassendi, but the
result was the same each time. A colour image was taken
earlier at 01:21UT but shows not colour on S wall as it was
saturated. ALPO/BAA weight=2.
On 1992 May 13 at UT 20:16-21:29 several observers reported a TLP in
Plato mostly concerning the visibility of floor craterlets, however
observer seeing varied from III-V. North (UK, 18.25" reflector)
reported "Colouration and floor craterlets very prominent. Seeing
Antoniadi V, Transparancy Poor.". Foley (Kent, UK, 12" reflector
seeing=III-IV) found the floor to be bright and in the better moment of
seeing detected floor craterlets. The WNW spot was misty some of the
time. Moore (Selsey, UK, 15" reflector, seeing V) had very poor seing
conditions. J.D. Cook and M.C. Cook (Frimley, UK, 3.6" reflector,
seeing II-III) used a CCD camera at 22:11 UT. The Cameron 2006 catalog
ID=445 and the weight=5. The ALPO/BAA weight=2.
Gassindi 1966 Oct 25 UTC 22:30-23:10 Observed by Moore and
Moseley (Armagh, Northern Ireland, 10" refractor) and Sartory
(England, 8.5" ? reflector) "2 faint blinks (Eng.) on NW (IAU
?) wall. (Indep. confirm.?). NASA catalog weight=5. NASA
catalog ID #987. ALPO/BAA weight=4.
On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector,
seeing=III) found the region around the cleft on the souther rim to be
out of focus - however atmospheric conditions were turbulent until
23:18UT. An unsual dark triangular region (long base against rim) was
seen to extend from the inner rim at 12 o'clock onto the floor for 13-
16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK)
found the south east to soth west to be obscured again, but not as
badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the
dark region had 2 white bands on the side and the south west wall was
blurred like it was on the 20th July - this time tough colour was not
present. There were also two light patches on the floor. Mosely
(Coventry, UK) observed the south wall at x120 and found the wall out
of focus at the 11 o'clock location. Through a yellow filter he saw a
"white mistiness: on the top of the southern rim and only the south
east cleft could be seen (no colour). By 22:40-23:00 the effect had
cleared up. No dark triangular patch was seen. When Marshall (Surrey,
UK) observed (22:30-03:00) nothing unsual was seen, though a sketch
provided shows a light patch on the floor located at 11 o'clock. All
observations, made by all observers had some atmospheric turbulence,
however trsnparency was good. The Cameron 2006 catalog ID=225 and the
weight=5. The ALPO/BAA weight=3.
Aristarchus 1880 Jan 23 UT 20:00? Observed by Trouvelot

Aristarchus 1971 Mar 08 23:00-23:10 Observed by Lyttle (Northern
Ireland, 6" reflector, x98) "Suspicion of white spot W of N-S radial
band, slightly brighter than wall. Diam. @5-6km. Area affected by temp.

appeared to the NE of the crater, and persisted for 15 min,
before rapidly fading away. NASA catalog weight=3. NASA
catalog ID #505. ALPO/BAA weight=3.
On 1985 May 31 at UT 20:23-22:00 G. North (Sussex, UK, turbulent
seeing) found Torricelli B at 20:23 to be mauve in colour and to be
very bright. However the colul had gone by 20:29UT. "Varied in albedo
2s then image blurred at 5-10s (atm) at 2034 became pink). At 21:35UT
M. Mobberley (Suffolk, UK) found a white patch in the crater centre and
a mag 8 flash was seen (confirmed independently by a 2nd observer ~
113km away)- there was no shadow. At UT 20:30 P.W. Foley (Kent, UK,
12"reflector, seeing excellent) found no colour, but the brightness was
changiong and he confirmed the bright patch on the crater's floor,
variable 22:15-22:25UT, "then expanded over rim". The Cameron 2006
catalog ID=277 and weight=5. the ALPO/BAA weight=4.
In 1962 Dec 09 at UT 07:36 Wildey and Pohn (Mt Wilson, CA, USA, 60"
reflector) observed that Oceanus Procellarum was 1.13 magnitudes
brighter than normal. Observation at sunrise and is abnormal if area
measured was mare. If it were an east facing wall it would be normal.
The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
In 1962 Dec 09 at UT 07:42 Wildey and Pohn (Mt Wilson, CA, USA, 60"

(Mallorca, Baleares, 4" refractor x250) "Red glow in crater at 2140,
then clouds stopped obs. After clouds, floor was abnormal rose color"
NASA catalog weight=5. NASA catalog ID #879.
ALPO/BAA weight=4.
On 1978 Mar 21 at UT 20:57 an Unknown observer observed a TLP in
Aristarchus crater. The details for this report are still being looked
up in the archives. In view of the uncertain details this TLP has been
given an ALPO/BAA weight of 1.
Torricelli B 2002 Oct 18 UTC 20:56-21:59 Observer: G.North (UK, 8"
reflector, x134, Seeing Antoniadi IV, Transparency good) - thought that
Torricelli B was perhaps a little brighter than expected, especially
when compared to Moltke and Censorinus based upon past recollection of
relative brightnesses at this colongitude). Slight bluish tint seen as
well. The ALPO/BAA weight=1.
On 1965 Jun 12 at UT > 00:00 an unknown observer (Porta?) reported that
the area of Herodotus and the Cobra Head expanded and the colour went
to rose. The next night the floor was normal. In filters, phenomenon
accentuated in orange. The cameron 1978 catalog ID=880 and weight=3.
The ALPO/BAA weight=2.
On 1975 Apr 23 at UT 20:30 J-H Robinson (Teighmouth, Devon, UK, 260mm
reflector, x200). Observer was observing since 20:30UT, at 21:00UT
though they noticed red on the outside south wall of Aristarchus, a
hazy ill defined area that was larger in a red filter than in blue
filter, and outside east wall was bright in red. At 21:08UT the outside
west wall of Aristarchus no longer gave a colour blink reaction, and at
21:22UT the colour blink on the southern end of the crater ceased, but
the image blur remained (in both red and blue filters) despite the rest
of the crater being sharp in detail. Observations ceased at UT 21:35
because the blurring at the southern end seemed to be normal and this
was confirmed when checked with photographic atlases. Other craters
such as Proclus, Pickering, Tycho, Gassendi, Copernicus, Alphonsus,
Plato, Menelaus, Manilius, Linne and Theophilus, showed no colour blink
reactions. However Picard had a red bright blink from 20:30-20:40 and
the permanant blink on the N. Floor of Fracastorius was detectable.
Also Plato floor shadings were clearer in red than in blue -
intermittently. This is a BAA lunar section observation. No estimation
of transparency or seeing is given, nor any comment on whether spurious
colour was seen in any craters visually. ALPO/BAA weight=1.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi
III seeing, 12.5" reflector) "Intensely bright craterlet south of central
peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed
the crater was highly luminous at 21:20, and surrounded by a blue halo that
had a darker blue band within it. This craterlet faded over time, and by 21:20
Moore considered that it was no longer prominent, by 21:22 Foley confirmed the
reduced brilliance, and by 21:30 Moore considered it to be perfectly normal.
Moore considers the nimbus effect to be normal. The Cameron 2006 catalog ID=
306 and weight=5. The ALPO/BAA catalog weight=3.
On 1980 Sep 22 at UT05:00? D. Louderback (South Bend, WA, USA, 8"
reflector, x140 and 2.5" refractor) observed in Promitorium Agarum that
one of his pre-designated points, called "A", through to "C and "D" was
at least 5 brightness points brighter in red than in blue light. The
reverse was true on Sep 25th. Tonight the red seemed to be on a narrow
strip on the western edge. The Cameron 2006 catalog ID=109 and the
weight=3. The ALPO/BAA weight=3.
On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar
telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a
dusky dark gray area just north of Herodotus and just south of the
Cobra Head. The interior shadow on the east of Herodotus by comparison
wad black and distinct. No change was seen when viewed through a
rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA)
was observing at the same time but had better observing conditions and
could see detail in this region, suggesting that it was not a TLP.
There is no Cameron entry for this report. The ALPO/BAA weight=1.
On 1963 Nov 28 at UT 22:30-00:00 Fisher (Colefax, CA, USA, 8"

Bullialdus 1979 Oct 04 UT 20:24-21:25 JH-Robinson (Devon, UK,
260mm Newt. x200 Seeing Antoniadi IV-V, Transp.=haze) observed a two
bright points on the south west floor patch to be brighter in red than
in blue at 21:12. The effect was still present at 20:36 but back to
normal by 20:43-20:48. Amery (Reading, UK) found a possible brownish
tinge on the west wall, though spuroius colour was present elsewhere on
the Moon. Foley found the WSW corner darkened in blue light. Cook found
pink on south rim of Bullialdus and Pedler found Bullialdus to be a
confused mass with bright and dusky spots and patches - no colour seen.

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.

On 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a
darkening in the Cobra Head, Schroter's valley area of Aristarchus -
the best example that he had ever seen. The Cameron 2006 catalog ID=474
and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section
circular 1995 Oct, p125 and personal communication from David Darling
to the BAA on 6/6/1995. Note it is uncertain whether this refers to the
Clementine mission or to somebody who observed during the Clementine
mission, or somebody with that surname. Anyway if it is the Clementine
mission then the date is wrong - possibly the year should have been
1994? The Cameron catalogue does actually mention a TIFF on Clementine
mission? The Cameron 2006 catalog ID=474 and the weight=3. I am
assuming that the year should be 1994 and not 1995? The ALPO/BAA
catalog weight=1 until we can find out what the correct date is?
Aristarchus 1964 Jul 31 UT 02:00-02:23 Observed by Bartlett
(Baltimore, MD, USA, 5" reflector x180) "Deep ravine on E.glacis
interrupted midway of its length by apparent break just below
rim of craterlet assoc. with EWBS. Normally, ravine is seen
continuous. Probable obscuration at pt, of break." S=7, T=5.

Triesnecker 1966 Jul 10 UTC 02:00-02:15 Observed by Allen (Cambridge,
England) and other observations by Corralitos Observatory (Organ Pass,
NM, USA). Described in NASA catalog as: "Faint illum. of a ridge in
shadow; faded quickly (in BAA judged dubious). Not confirmed by
Corralitos MB." 12?" refractor (x280) used at Cambridge and at
Corralitos 24" reflector. NASA catalog weight=1 (very low). NASA
catalog TLP ID No. #956.
On 1996 Feb 12 at UT 07:30-08:27 J.Sandel (Caycee, SC, USA)
noted a contrast effect inside Tycho at sunset. At 07:30UT there
was a slight, but definite illumination of small areas of the
crater floor west of the central; peak. Also seen by T. Ferrel
(Lawrenceville, GA, USA, SCT C8). This was oval in shape and
gray in colour - Ferrel noted some diffuseness. It brightened
over 30 minutes. At 08:11UT a definite brightness fade noted in
Tycho's central peak. The crater floor had increased
illumination of entire crater floor. ALPO/BAA weight=3.
On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52"
reflector) observed that central craterlet in Plato was
unusually bright and shows up as a bright white spot on his
sketch - though this might have been artistic license in his
sketch. His written notes refer to the unusual lack of a rim
(especially the northern part) to this craterlet.
The ALPO/BAA weight=2.
Herodotus 1969 Aug 09 UTC 03:00-04:03 Observed by Gomez (Sabadell,
Spain) desribed in NASA catalog as: "Bright point on SE wall at 0300h,
gone at 0322h. Brightened in blink device (Eng.) at 3:30:50, 3:41:36,
04:03:21" 12" reflector x155,x258,x388. Average weight=3 in NASA
Catalog.
ALPO/BAA weight=2,
James Short, Dr Harris and Mr Stephens saw initially a streak of
light on the shadowed floor of Plato. They were not expecting to see
any light to reach the floor. Shortly afterwards they saw a second
streak of light parallel to the first and this shortly divided
into two. Gaps in the mountains were found for both streaks,
but they were unable to understand why one of the streaks divided
into two. Cameron's 1978 assigns this TLP an ID of 20 and a weight
of 5. The ALPO/BAA catalog assigns a weight of 1.
On 1988 May 18 at UT01:00-02:35 Lubke (Middleton, WI, USA, 8"
reflector, x130) reported that Aristarchus glowed "like an out of focus
star varying with the atmosphere". Darling (Sun Praire, WI, USA, 20x60
binoucular) and Spain (Fairdale, KY, USA, 7x35 and 20x60 binoculars, S=
6/10) found that both Copernicus and kepler were brighter than
Aristarchus in Earthshine. Aristarchus itself looked unusual, though
Spain did not see Aristarchus at all. Darling and Wieir (20x60
binouculars) agreed that it appeared as a star-like point in
binoculars. Cameron 2006 catalog ID=326 and weight=0. ALPO/BAA
weight=1.

On 1990 Apr 26 at UT 19:30-20:30 S. Beaumont (Cambridge, UK, seeing=II,
very good) observed Aristarchus to be "very bright" in Earthshine - it
varied in brightness. However she could also see the edges of the mare
and the west limb clearly. Grimaldi was slso seen. Cameron suspects
that these are atmospheric effects. The cameron 2006 catalog ID=400 and
the weight=0. The ALPO/BAA weight=1.
On 1990 Apr 26 at UT 19:30-20:30 S. Beaumont (Cambridge, UK, seeing=II,

On 1988 May 19 at UT01:14-02:30 D. Darling (Sun Praire, WI, USA, 7x35
binoculars) was able to see Copernicus OK, Kepler (only just) and
Aristarchus was invisible in Earthshine. He could not see the usual
bright areas in Earthshine either. D. Spain (Fairdale, KY, USA,
3.5"reflector, x30-277) could not see anything in Earthshine. Lubke
(Middleton, WI, USA, 8" reflector, x75 and x130) though was able to see
Aristarchus and it was brighter than its surroundings, however it was a
lot fainter than on the 18th May. Cameron suspects that this was
atmospheric in origin and not a TLP. The Cameron 2006 catalog ID=329
and weight=0. The ALPO/BAA weight=1.
On 1989 Apr 09 at 00:00? R.Horton (N.Scituate, RI, USA, 6" reflector)
found Aristarchus (and Kepler) to be much less bright than Copernicus.
Photographs show this. The Cameron 2006 catalog ID=359a and the weight=
3. The ALPO/BAA weight=2.
On 1989 Apr 09 at UT 00:00? R. Horton (N. ScN. Scituate, RI, USA, 6"
reflector) took an Earthshine photograph that revealed Copernicus to be
brighter than Aristarchus and Kepler. Cameron comments that usually
Aristarchus is the brighter and thought it a bit odd because Copernicus
should have been less visible, being nearer the terminator3 The Cameron
2006 catalog ID=359a and the weight=5. The ALPO/BAA weight=2.
On 1989 Apr 09 at UT 00:00-04:45 D. Darling (Sun Praire, WI, USA, 11"
reflector, 3" refractor, S=9/10 and T=6) observed the central peak of
Tycho in Earthshine and that the crater "glowed". However Earthshine
was exceptionally bright tonight. The Cameron 1978 catalog ID=359b and
weight=3. The ALPO/BAA weight=1.
In 1821 May 04 at UT 21:30-22:00 Ward (England? Large aperture
telescope, x80), Bailey (England?) and Olbers (Bremen, Germany,
refractor) observed in the Earthlit part of the Moon an apperent small
comet like feature extended from Aristarchus towards Grimaldi. The
light was similar to a glow worm. The observer had never seen anything
like it. The cameron 1978 catalog ID=89 and weight=3. The ALPO/BAA
weight=4.
On 1990 Apr 27 at UT20:00-20:30 P. Mugridge (Surrey, UK) observed a
bright light "sometimes 3 lights in form of triangle" in Oceasnus
Procellarum (56W, ~25N), roughly mid way between Schroter's Valley and
Briggs. "Haze surrounds as a mist or fog. poss. < at end of obs."
Cameron comments that this may have been as a result of contrast in the
strong Earthshine. Foley even contemplates if it was a
misidentification of Aristarchus. Cameron comments that it is probably
not due to terrestrial atmosphere. The Cameron 2006 catalog ID=401 and
the weight=1. The ALPO/BAA weight=1.
On 1989 Apr 09 at 02:13 was seen to be not very bright in binoculars,
despite visibility of Earthshine in general as being exceptional.
Darling confirmed this at 02:31UT, though it was quite bright in a
17" reflector,but Herodotus could barely be seen. Weier claimed to be
able to see Aristarchus with the naked eye. At 02:08 the brightness was
found to be 5.0 for several measurments. The observing team ware from
the Maddison Asgtronomical Society, WI, USA. The Cameron 2006 catalog
ID=359b and he weight=3. The ALPO/BAA weight=2.
