Cleomedes Alpha 1993 Sep 03 UT2200-22:20 G. North (UK, 18.25"
reflector, x86 & x144) observed it to be a strikingly brilliant
'splodge' seen in the mostly shadow filled interior of
Cleomedes, and around this splodge was a faint halo extending
symetrically in an eastwards direction. The splodge was the
mountain Cleomedes Alpha. Strangely no shadow from the mountain
was seen to be cast onto the halo on the east. Observer alerted
other observers by phone, and upon returning to the scope found
that the splodge had faded in brightness and continued to fade
over the next hour as one would expect from a mountain at
sunset. Some heavy spurious colour was present. J. Cook & M.
Cook (Frimley, UK) observed at 22:20-22:25 and found the bright
splodge, but no halo. M. Cook re-observed later and confirmed
normal fading of splodge. Roscoe observed from 00:30UT next day,
but by that time Cleomedes Alpha had set and was no longer
visible in the shadow filled floor. S. Beaumont had observed
earlier at 20:00 but had recorded all as normal in Cleomedes.

On 2009 Oct 09 UT11:00-11:04 NASA's LCROSS upper centaur stage,
followed 4 min later by the observation spacecraft, is due to impact
into a the crater Cabeus in the hope of kicking up some dust and
possible frozen volatiles. Note that this description is intended for
observers on the date of impact and it is doubtful that any new
science could be achieved by re-observing the same area months
after the impact. If you are observing on the date of impact, then
please observe around 11:00-11:04UT and ignore the predicted times in
the headings. However this report is included as techniqcally
if something is seen it is a TLP, albeit man-made! For those observing
on the date in question here are a few observing tips to maximize
the science of your observations: (1) If you are imaging, then please
try to obtain images before the impact because you can then subtract
these from images taken during the impact and hence show up faint
changes that you might normally miss. (2) If you have a spare scope and
camera,use this to observe through filters such as UBVR or I, or if you
have narrow band interference filters, try observing in
say Hydrogen Alpha, Methane, OH, or indeed any volatile that you
might expect to see in a comet (the main source of water at the poles).
(3) Please try checking the area long after the impact, just in
case other effects might trigger a TLP. (4) Please go to some trouble
to ensure accurate timings- these will be essential in order to
understand the sequence of events - assuming any are seen. Timings can
be obtained using a short wave radio or via a GPS. Note that you should
always use UT or UTC. (5) Please send any observations that you make
into the upload section of the LCROSS campaign observers web site. If
you belong to an astronomical society e.g. BAA or ALPO, then do please
send copies of your observations to the Lunar Sections of your society
or club. (6) Finally this desription will be updated a day or two after
the planned impact.
On 2009 Sep 09 UT23:31:43 P.Grego (St Dennis, Cornwall, UK, seeing II-
III) suspected a flash south of Cabeus, just beyond the terminator.
It was not bright, and lasted a fraction of a second. Thinks it might
have been illusory as he saw some fainter flashes (cosmic rays?)
during that nights observing session. ALPO/BAA weight=1.
Alphonsus 1980 Jul 04 10:35-10:48UT Observed by B. Hobdell (St
Petersberg, Florida, 6cm refractor and 20cm reflector. x130. Seeing
Antoniadi I) "A dark discolouration was seen on the east floor,
adjacent to the central peak and the dark area on the west floor
directly south of the prominent dark area. Hobdell thinks it was a
small crater on a secondary rill with slight venting discolooration,
seen in Orbiter pictures. A sketch was made and the BAA alerted. The
sketch matches the dark spots in Alphonsus (normal aspects?)" cameron
comments that the sketch looks like the aspect in the Lick composite
photos. Foley comments that dark at this lunar age is not normal. A UK
observation made 14 hours later looked normal. Cameron 2006

On 2009 Sep 11/12 UT23:28-00:00 M.C. Cook (Mundesley, UK, 90mm Questar,
x80 and x190, seeing II and transparency moderate-poor) observed
pink on the north west rim of Tycho and green-blue on the inner
SW rim. No sign of colour elsewhere on the Moon except for the
S-E rim of Plato that was red. The Moon was about 20 deg in altitude
at the time. The effect had gone by the end of the observing period.
A simulation of spurious colour in different directions
was generated by the BAA Lunar Section and found to possibly account
for these colours, although there should have been some strong colours
seen elsewhere in Tycho and none were. The BAA/ALPO weight=2.
On 1878 Oct 18 at UT 21:00? Gaudibert (France?, 4" refractor) observed

Aristarchus and another one from Schroter's valley. By 02:45UT
Aristarchus was starting to be difficult to see and had occasionally a
bluish cast. By 03:00UT the crater could only barely be seen. This was

On 1980 Apr 19 at UT20:30-22:59. The following is quoted from the
Cameron 2006 catalog.... "(Buczynski) alerted by colleague (Greenwood)
who used filters W15 (IR), W25 (red), W44A (blue), & W58 (UV) and had
located a possible blink in it. (Bucz) used W15, W44A & W25. C.P was
very bright in W25 (red), dull but vis. In W44A (blue) & floor was
noticibly darker in W44A than in W25. Bright cp vis. In W15 & floor was
of a light shade. Other craters checked for color, none found. In 44A
floor lost some definition (gas?). Sketches from Bucz. & Greenwood.
(Pedler) at 2140, floor area around cp was seen in white & red as
normal but blink was vis in white, darker in blue. Checks of other
features were negative. (Amery) small dark center & small dark area -
not shadow - under S wall. N wall obscured by dark area extending N
onto surrounding mare. (normal?) which was difficult to focus (gas?).
At 2155 N wall now sharper & dark area less intense. Craterlet Cameron
in N wall clearly seen which was invisible 1/2 h earlier. (Saxton)
whole crater flashed and blinked at 2155. Could see detail in brighter
W 1/2 of crater - not seen earlier. At 2205 seeing poor, at 2215 it was
normal. (Blair) at 2155 used red & blue filters & in blue it was darker
than in red. W. wall not well defined. (J. Cook) saw spurious color on

Daniell 1979 Apr 02 UT 21:45-22:14 Obseved by Madej (Huddersfield, UK,
158mm reflector, f/4.2, x36-110, seeing II-III) "Obscuration seen" BAA
Lunar Section Report. Cameron says that this was a bright white cloud
that covered three quarters of the crater. A yellow filter was used at
21:48, but the cloud was still white, albeit thinner (at x110). By
22:14UT the TLP was barely visible and again no colour seen. Buczynski
(Lancaster, UK, seeing = poor) saw spurious colour. Later (22:31-
22:46UT?) Mellor obtained some photos, but these revealed no colour.

On 1980 Apr 20 at UT 19:25-23:43 P.W. Foley (Kent, UK, 10" reflector,
seeing II-III) found that Aristarchus was very bright in Earthshine
(also found on the photographs that he took), giving off a blue
"incadescence", the CED brightness reading was 5. Occasionally Foley
could see a star-like point in the south east corner. For comparison in
brightness he used highland terrain near to Grimaldi (CED=2). By
comparison, Buczynski and Lord, could not see Aristarchus. Earlier,
Geenwood saw the crater easily as a star-like point with a diffuse
exterior glow. Cameron says thyat this was confirmed by Buczynski and
Lord (?). At 20:35UT Amery decided that Aristarchus looked brighter
than normal. Pedler though described the crater as "small dim nebulous
blue or blue-green" that was invisible by 20:27UT. At 20:28-22:01 Blair
could not detect Aristarchus, nor could J-H Robinson at 20:40UT though
he did see it at 20:55UT as both diffuse and blue. Ricketts detected a
blow glow with irregularly spaced flashes of roughly 5-10 sec apart.

On 1983 Jan 19 at UT 18:00-19:00 G. Amery (Reading, UK) discovered that
Aristarchus could not be seen in Earthshine, this was odd because less
prominent features could be seen. Other observers (Moore and Foley)
confirmed the very low brightness of the crater. The Cameron 2006

On 1980 Apr 20 at UT21:12-22:45 J-H Robinson (Teighmouth, UK, 10.5"
reflector, x180) found, using a Moon Blink device, evidence of colour
on the flor patches of Fracastorius crater, brighter in blue than in
red. Also the floor to center varied in brightness in blue and in red.
Peters observed in white light and found the south east-south wall had
a slight orange cast and when a Moon blink was used it was less bright
in blue than in red light. M. Cook found spurious colour on the south
rim and also on Mons Pico. There was a colour blink reaction on the
southeast floor of Fracastorius - this was both faint and blurred and
not seen in white light. A.C Cook detected the permanent blink in the
south east floor of the crater at 21:47 and a fainter one in the north
west (marginally brighter in red than in blue). J.D. Cook found no
colour with the Moon blink device. 21:22-22:10 P.W. Foley got a strong
colour reaction with the Moon Blink device - brighter in red than in
blue and detected a pink colour visually on the south east wall 22:10-
22:45 (this did not give a blink effect though). Cameron 2006 catalog
ID=88 and weight=4. ALPO/BAA weight=2.
Linne 1867 Aug 06 UT 21:00? Observed by Buckingham (England?)

Apianus D On 2011 Oct 03 UT 21:00-21:20 F. Power (Meath,
Ireland, 11" SCT) observed changing colours (blue, white, and
red) on the inner western rim of this crater. He changed
eyepieces and moved the scope around to look at dufferent parts
of the Moon, but nowhere else exhibited anything similar. As
another test he asked his wife to have a look without telling
her what he was seeing. She confirmed the same effect. 5 digital
camera images had been taken. Most of these were out of focus
and the first one was saturated, however one of them showed a
approximately 35 km long, by 11 km wide (at the north) lopsided
carrot shaped orange colour to the western rim of Apianus D. No
similar strong colour could be seen anywhere else on the image,
nor on the other 4 images. This TLP is being given an ALPO/BAA
weight of 1 as the Moon was low, but an image taken looks
interesting.
On 1988 Nov 15 UT 19:15 Holmes (Rockdale, UK, 215mm Newtonian) noticed
the Censorinus apron (just east of the crater and including the rim)
was fuzzy but the crater was clear - a sketch was provided. A BAA Lunar

On 2001 Apr 29 at UT 20:50 R. Braga (Italy) reported that without any
filter, the brightness of the east wall of Torricelli B was halfway
Torricelli C (faintest) and Moltke (brightest). By insering a Wratten
25 red filter though, the crater was slightly more evident. However
using a blue Wratten 39A filter, the crater vanished completely, whilst
Toricelli C remained. The ALPO/BAA weight=3.
On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP
coordinator, Patrick Moore, to report a possible colour anomaly in
Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing
unusual. However by this time North was reporting that, the colour was
fading. Two other BAA members were alerted, but were clouded out. The
ALPO/BAA weight=3.
Webb (England, using a fluid achromat) saw brilliant minute spots and
streaks in Mare Crisium dotting its surface. This was seen near first
quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall
had all seen it this way at times. Cameron 1978 catalog iD=111 and
weight=3. ALPO/BAA weight=2.
On 1984 Apr 08 UT 19:50 Mobberley (14" reflector, x194, seeing
III-IV, Transparency Fair-Poor, Cockfield, UK) found that
Torricelli B's shadow was 1/2 the way across the floor, which
was normal, but that there was a very dar grey/brown shroud
around the carter, out to several radii.
The ALPO/BAA weight=1.
On 1980 Apr 22 at UT20:30 R.Rohslberger (Hittfield, (near Hamburg) West
Germany, 8" reflector, x170 25mm occular used, 300mm focal length?)
took some photographs using projection. One of these recorded an
apparent "ejecta curtain". Cameron considered lens flare, but the other
photographs did not show this. If real then the plume was at a height
of ~40km and the ray was ~130km. Cameron concludes that this was an
impact photograph. The Cameron 2006 catalog ID=90 and the weight=5. The
ALPO/BAA weight=3.
On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia)
noted that Mons Piton was too bright near the terminator and was
surrounded by shadow. A sketch was made. The mountain appeared
segmented with one thin shadow line. The mountain looked like a
Mexican Sombrero hat. This appearance is normal. What was
abnormal was that Piton was brighter than Proclus, and only
slightly fainter than Censorinus. The CED brightness
measurements were normal Piton=3.6, Proclus=3.5 and Censorinus=
3.7. Please check to see whether this is still the case. The
cameron 2006 catalog ID=221 and the weight=3. The ALPO/BAA
weight=1.
Dome W. of Manillius 1965 Dec 30 UT 10:35 Observed by Newport (England,
4" refractor x180) "White patch or haze, everything else was sharp"
NASA catalog weight=3 (average).
On 2009 Nov 25 UT18:42-21:03 P.Abel, T.Little and C.North (Selsey, UK,
15" reflector, seeing II-III, transparency very good), all saw visually
a brownish tinge on the north west rim of Eratosthenes crater. P.Abel
made a sketch and T.Little took some high resolution CCD images, some
of which were through coloured filters. Checks were made for spurious
colour, but none was seen elsewhere on the Moon. The eyepiece was
changed but this made no difference. M.C.Cook (Mundesley) was observing
with a smaller scope at the same time, but saw no colour, however
observing conditions were worse. W.Leatherbarrow (Sheffield, UK) was
observing with a instrumenet mid way in size, and saw a brownish tinge
in the NW rim area, but saw a similar colour elsewhere and put this
down to spurious colour. Normally multiple observers seeing the same
thing would result in a weight of 4, however as this was only observers
at Selsey and some of the evidence contradicts, I am allocating an
ALPO/BAA weight=3.
Pallas-Schroter 1953 Nov 13 UTC 02:00 Observed by L.Stuart (USA)
"Saw and photographed a bright spot on term. between these two
craters. Used Kodak 103aF3." NASA catalog weight=5 and catalog
ID #559. ALPO/BAA weight=5.
On 1969 Nov 18 at UT 04:22 Loocks (Valparaiso, Chile, 12" reflector)
observed a flash of light of magnitude 12. Cameron speculates a meteor
and mentions the apollo 12 watch. The Cameron 1978 catalog ID=1214 and
weight=1. The ALPO/BAA weight=1.
Eratosthenes 1947 Jan 30 Mean Col. 16deg. Observed by Hill (UK) "Main
peak of massive central mountain group appeared to be in a shadowless
having regard to it's claimed height of 6,600 ft. The whole of the
floor to the west should have still been in darkness. Instead
immediately to the west was a dark (intensity 1.5-2) region extending
almost to the foot of the bright inner wall and very diffuse in
outline. The observation could not be followed through due to
increasing cloud, but on the following night all was normal."
On 1936 Oct 25 at 01:35 UT W. Haas (Alliance, OH, USA, 12"
reflector) saw small bright spots on the floor of Eratosthenes,
(Pickering's atlas 9A, col. 30deg, shows no spots - according to
Cameron). Cameron 1978 catalog TLP=417 and weight=4. ALPO/BAA
weight=1.
On 1982 Jul 01 at UT 02:23-02:58 Robotham (Springfield, ON, Canada,
seeing=II) found that the west rim of Pytheas crater was a very bright
yellow-white, indeed brighter than Proclus. At lower magnifications,
Pytheas was one of the brightest spots on the Moon. The Cameron 2006
catalog ID=173 and weight=2. ALPO/BAA weight=2.
Piton 1958 Sep 23 UT 00:00? Observed by Moore? (UK?) "Enveloped
in an obscuring cloud-like mist" NASA catalog ID 697. NASA
catalog weight=2. ALPO/BAA weight=2.
Messier and A 1966 Dec 22 UT 06:00-06:30 Observed by Kelsey (Riverside,
CA, USA, 8" reflector, x200, S=G, T=P) "Blinks on floors of both
craters (blink device not stated)" NASA catalog weight=2 (low). NASA
catalaog ID #1004.
On 2011 Oct 07 UT 21:45 Gassendi observed by P. Grego (St
Dennis, UK,300m Newtonian, x150, seeing III, intermittent cloud)
- whilst producing some sketches of the crater - observer
noticed a faint point of light inside the shadow filled
interior, two thirds of the way out from where the central
peaks should have been, towards the SE rim. Some uncertainty in
being sure about this spot and after interuption by cloud it was
not seen later that evening. ALPO/BAA weight=1 to refelct
uncertainty of observer.
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.
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."
W. of Mare Humorum (50W, 25S) UTC 00:00? Observed by Mac Farline
(England?) "Bright Point" NASA catalog weight=2 (low). NASA catalog ID
719.
In 1820 Oct 17 at UT 20:00 an unkown observer reported in Mare Imbrium,
south of Sinus Iridum (30W, 40N) some brilliant spots. The Cameron 1978
catalog ID=80 and weight=1. The ALPO/BAA weight=1.
Plato 1966 Dec 23 UT 06:15-07:10 Observed by Kelsey (Riverside, CA,
USA, 6" reflector, S=P, T=G) and Coralitos Observatory (Organ Pass, NM,
USA, 24" reflector +Moonblink) "3 brilliant spots on floor, all showed
blinks, (permanent colored Ground features ?). Not confirmed by
Corralitos MB." NASA catalog weight=2 (low). NASA catalog ID #1005.
Gassendi 1967 Mar 22 UTC 19:39-19:43 Observed by Mosely (Armagh, N.
Ireland, 10" refractor, x360) "Red color & blink strongly suspected
in small area centred on junction of 3 clefts 1/2 way from c.p. &
ESE wall. Well-defined & did not note change during obs. period.
Clouds terminated obs. till 2120 when it was not seen." NASA
catalog weight=3 (average). NASA catalog ID #1018.
On 1989 Sep 12 at UT00:58-02:25 D. Darling (Sun Praire, WI, USA, 12.5"
reflector, x159, S=7/10) observed similar light conditions to 1989 Jul
15. At 02:00 he observed pink on the south west wall of Aristarchus
crater. At 01:24UT the Aristarchus ray was yellowish, however the
entire Moon had a grey-yellow tinge of colour. Chromatic aberation was
observed at 01:56UT. By comparison Gassendi was checked and had no
colour. At 02:10 the crater wall of Aristarchus was unusual and was
quite different in appearance to rims of other craters. The cameron
2006 catalog ID=375 and the weight=1. The ALPO/BAA weight=1.
M. Cook of Frimley, UK observed a brightening of the crater during
this observing session. The cameron 2006 extended catalog ID=346 and
weight=3. ALPO/BAA weight=2.
G. Ward (a lunar observer for 15 years) observed an area just south
west of Mersenius C to be blurred and in a greenish cloud. The green
colour was more like that of dead grass than one gets from a neon bulb.
The effect was seen from 04:50-04:57UT, but could have been going on
before it was first noted at 04:50-UT. Seeing was 6-7/10 4" Refractor
(2 element). refractor had been used hundreds of hours before (over a
10 year period) with no similar colour was seen. The observer checked
other areas but did not see any similar effects. They also rotated and
changed eyepieces, but this made no difference to the TLP. The TLP site
seen was picked up on an image taken earlier at 04:47UT by W. Bailley,
from Sewell, NJ, USA. Unfortunately the area concerned, a mountain on
the image, was saturated and so we cannot tell if a colour was present
there and the seeing was poor.
Aristarchus 1975 Oct 16 UT 20:00? Observed by Foley (Kent,
England, 12" reflector) "Deep blue-viol. spot in NW (IAU?)
interior corner." NASA catalog weight=3. NASA catalog ID #

ALPO/BAA weight=1.
On 1965 May 12 at UT 19:10 E. Penzel (Rodewisch, East Germany) was
taking a sequence of images during the impact of the Soviet Lunik 5. He
detected a tens of km scale elongated cloud after the impact over a
duration of 9.5 minutes. However there are differences between the
images elsewhere on the Moon, possibly due to different exposures or
some other effects and it is not 100% sure that what he detected was
impact debris/cloud?. The ALPO/BAA weight=3.
Proclus 1970 Oct 12 UT 00:54 Observed by Bartlett (Baltimore, MD, USA,
4" reflector, 51x-181x) "Floor darkened to intensity 1.5 deg (albedo) &

On 1988 Sep 23 at 19:40-19:55 & 20:36-20:41 G. North (760mm
Coude Rrefractor, x250, Royal Grenwwich Observatory,
Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55
image very unsteady. All seems normal in other crtaters with
the exception of Arcimedes. Much of the rim seems indistinct
apart from a 1/4 length of the west rim. Strongly suspected
that this was due to a combination of seeing and illumination.
UT 20:02-20:06 - checked the area with a lower magnification
10" Astrographic Refractor - the crater seems more normal, so
suggesting that the theory was correct. 20:36-20:41 returned
to the 30" reflector, and the crater appeared similar to the
start of the session. This is almost certainly not a TLP, but
it would be helpful to have some images or sketches to check
this theory out. Weight=1.
On 1987 Mar 13 at UT02:00-03:00 De Groof (Belgium, 8" reflector x150,
seeing=clear) noted that the north west part of Aristarchus had a blood
red shimmering filling the whole crater. A video by Mobberley some 18
hours later, shows variation in Aristarchus. Cameron 2006 catalog ID=

focus on (he had never seen it like this before). Also the interior of
Aristarchus was invisible. Brightness measurement taken and a sketch
was made. The Cameron 2006 catalog ID=222 and the weight=3. The
ALPO/BAA weight=3.
Proclus 1972 Nov 21 UT 21:30 Observed by Farrant (Cambridge, England,
8.5" reflector, x130) "Thickened bright ring remained, but the dark
patch had disappeared. (dark patch prob. real temporary phenom. as it
was seen nr. FM when contrasts are strongest, yet disappeared" NASA
catalog weight=1 (very low). NASA catalog ID #1351.
On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50)
observed a bright flash (~0.3 sec duration) near to Copernicus (20W,
9N) with rays to the south east whilst he looked through a finder
scope. Moore, who studied the drawing, suggests that the area of the
flash was near Copernicus. However Cameron says this cannot be the case
if the flash was in darkness as mentioned in the BAA Lunar Section
circular. She comments that it might have been a meteor? The Cameron
2005 catalog ID=28 and weight=1. The ALPO/BAA weight=1.
Gassendi 1940 Aug 20 UT 03:25 Observed by Haas (NM?, USA, 12"
reflector?) "Largest bright spot on SE pt. of floor had I=8.6
(real changes? see @ '#649, 474, & 475, all similar change)."
NASA catalog weight=4. NASA catalog ID #472. ALPO/BAA weight=2.
1824 Dec 08 UTC 00:00? Observed by Gruithuisen (Munich, Germany)
"Bright fleck in SE part of crater" NASA catalog weight=4 (good). NASA
catalog ID #104. ALPO/BAA weight=2.
Aristarchus 1947 Nov 30 UTC 00:00? Observed by Favarger
(France?) "3 bright points on inner w. slopes." NASA catalog
weight=2. NASA catalog ID #499. ALPO/BAA weight=1.
On 1983 Jan 30 at UT 23:45 Chapman (England, UK) observed that
Censorinus was low in brightness. The Cameron 2006 catalog ID=199 and
the weight=4. The ALPO/BAA weight=2.
On 1983 Jan 30 at UT 23:45 P.W. Foley (Kent, UK, 12" reflector)
measured that the brightness of the region around Toricelli B was 2.3
(high) and there was a slight blue colour. The Cameron 2006 catalog ID=
199 and the weight=4. The ALPO/BAA weight=2.
Herodotus 1972 Jul 27 UT 2250-2350 M.Brown (Hutington, UK)
thought that he saw a pseudo peak in the centre of Herodotus.
He could not decide if it was real or an optical illusion.
ALPO/BAA weight=1.
Plato 1870 Feb 18 UTC 00:00? Observed by Gledhill (Halifax, England,
9" refractor) "Illum. of another group of craters different from group
in Aug. & Sep. obs. (date is F18 if phase is similar to Ap 1870)
NASA catalog weight=2 (low). NASA catalog ID #164.
