Grimaldi 1969 Jul 19 UT 20:39-20:45 Delaye (France, 25cm
refractor) saw a bright bluish spot near Grimaldi. 20:43 a
flash was seen by Thinon. Delaye saw flashes at 20:44 and
20:45. Between 21:00 and 23:00 (J. M. L.) da Silva (Rio de
Janeiro, Brazil, 19.5" refractor) saw a bright spot on the W
(IAU??) of Grimaldi. However there is a bright spot near
Grimaldi, so this maybe normal. NASA ID = 1167. The ALPO/BAA
weight=2.
On 1990 Mar 31 at UT 21:30 L. Jackson (England, UK?) observed a red
glow in Earthshine in Gassendi as shown in a sketch. Apparently
Gassendi can often show up red colours (according to Cameron) but
rarely is this seen in Earthshine. Foley saw the sketch and suspects
that the location was Gassendi. The Cameron 1978 catalog ID=397 and
weight=2. The ALPO/BAA weight=3.
South Pole 2011 Apr 08 UT 19:30-20:00 A.Kemp (Mold, Flintshire, UK) observed that the
Leibnitz peaks at the southern pole stood out sharply. However one of the peaks was “shining
like a spot light. So bright that I couldn’t make out its shape”. – image clear and steady with
excellent transparency and seeing in the 70mm f/13 refractor (25mm and 10mm eyepieces).
Inspections during the above time period revealed no changes in brightness. Previous
observations of this area had never shown such an unusual brightness, and Arthur likened the
brightness to “a maximum brightness of Venus shining amongst 2nd magnitude stars”. The
observer was an experienced observer. ALPO/BAA weight=2.
Alphonsus area? 1949 Jun 01 UT 22:06 H.P. Wilkins (Kent, UK, 6"
reflector x200) observed a bright white 1 sec stationary (mag
3?) flash in Earthhsine, close to the central meridian, and due
E of Theophilus (potentially in the general area of Alphonsus?).
The flash was approximately 6 km in diameter. ALPO/BAA weight=1.
On 1969 Jul 20 at UT 19:55-20:10 Delaye, Thinon, Donas, and Jourdran
(Marseilles, France, 10" refractor, x60) saw between 19:55-20:04UT
Aristarchus to be bright and in it pulsations with 10 sec duration. At
20:05UT it's spot brightened, at 20:08:50-20:35:50UT brightening and
pulsations of variable duration. At 20:55:50UT just a feeble flash.
Cameron comments that this is probably not atmpsheric effects as the
period is too long - also it was during the Apollo 11 watch. The
Cameron 1978 catalog ID=1175 and th weight=3. The ALPO/BAA weight=3.
On 1969 May 22 at UT23:20 an unknown observer reported some
brightenings with pulsations in Aristarchus crater, Cameron suspects
atmospheric aberrations. This was during the Apollo 10 watch. The
Cameron 1978 catalog ID=1136 and weight=1. The ALPO/BAA weight=1.
2005 Jul 13 UT 01:18 W.Watson (USA, East coast, transparancy:
heavy hazy cirrus, and the only other object visible was
Jupiter) observed a naked eye flash on the Moon in the northern
hemisphere, with a magnitude of -3 to -4. The ALPO/BAA weight=1.
On 1969 Jul 20 at 22:50-23:15UT Jean Nicolini (Sao Paulo,
Brazil, 12" reflector x430, S=II.5-III.5) saw a weak reddish
area on the north west(east?) wall of Eudoxus crater. An
English Moon Blink device showed it dark in blue and opaque in
red. Reddening remained unchanged while comparing it to
adjacent region and Aristotles. Colour index was toward dirty
orange. Colour most apparent in the good moments of seeing and
disappeared in the poorer moments of seeing, Cameron says that
this is opposite to what was expected if the effect was
atmospheric in origin and no colour was seen in Aristotles.

Theophilus 1978 Nov 08 UT 20:49-22:00 Observed by J.D. Cook
(Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV)
Orange discolouration seen on ESE crater floor. Moon blink
tried, but no blink detected. By 21:10 the effect had lessened,
but was still orange. By 21:50-21:58 the effect was smaller and
perhaps more on the SE of the floor. Colour confirmed by Foley.
Fitton may also have been observing. At 22:00 A.C. Cook observed
and commented that a darkish, perhaps brown-orange colour seen -
but suspected it was probably spurious colour - but by now the
seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of
several features, including Theophilus, had not noticed anything
unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect
a blink, but noticed intermittent darkining on the shaded area
on the E. floor, but seeing was now IV. The darkening was more
noticeable in blue than red light. BAA Lunar Section

On 1976 Feb 14 at UT23:35-0053 LeCroy (Springfield, VA, USA, 4.5"

area was bright, but was black in a red filter. At 00:53UT the features
were clear and the colour gone and the brightness had decreased to 9.

of being dark in the red filter, implying a medium). The Cameron 1978

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

continuous. Probable obscuration at pt, of break." S=7, T=5.
NASA catalog weight=4. NASA catalog ID #834. ALPO/BAA weight=2.
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.
Aristarchus 1970 Jul 26 UT 15:00? Observed by Sekiyuchi (Tokyo, Japan,
36" reflector) "Polarimetric and photoeletric anomalies on Moon" NASA
catalog weight=5. NASA catalog ID #1268. ALPO/BAA weight=5.
On 1940 Dec 25 at UT 10:00? Haas (New Mexico, USA, 12" reflector?)
observed the northern horn to be elongated by about 10'. The Cameron
1978 catalog ID=482 and weight=3. The ALPO/BAA weight=2.
On 1940 Dec 25 at UT 10:00? Haas (New Mexico, USA, 12" reflector?)
observed the southern horn to be elongated by about 10'. The Cameron
1978 catalog ID=482 and weight=3. 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,
On 1969 Jul 20 at UT 0845 McIntosh (Auckland, New Zealand, 14"
reflector) saw Aristarchus crater to be brighter in red light. This was
during the Apollo 11 watch. The Cameron 1978 catalog ID=1173 and
weight=3. The ALPO/BAA weight=3.
On 1975 Mar 18 at UT17:30 M.Kidger (Winterbourne Down, Bristol, UK,
60mm refractor, x36, very good conditions with a very sharp image and
the sky was almost perfectly clear apart from a very few small clouds).
In Mare Crisium it was observed that only a ray of Proclus could be
seen to cross the floor - normally there are at least four craters
visible inside mare Crisium on good nights and at least one being
visible under bad conditions. So despite it being very clear and the
image quality being good, the observer found it odd that no craters
were visible on the floor of mare Crisium. This is a BAA Lunar Section
report. The ALPO/BAA weight=2.
Observations made by Challis of Cambridge, and N. Pogson of Hartwell,
both of the UK. Before the occultation, Saturn's rings were
distorted. A dark border was seen around the Moon. Just before
re-appearance a sea green colour was noticed. Cameron 2006
catalog extension ID=5 and weight=2-5. ALPO/BAA weight=1.
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.
