On 1994 Jun 14 UT 21:45-22:00 G.Rogers (Crendon, UK, 3" Zeiss
refractor, sky conditions perfectly clear) reported seeing three
very large whitish clouds against the Moon. The strongest seemed
to "stem" from the vicinity of Santbech crater (crater
identified the next day from an atlas), and was a milk chocolate
colour near the stem. The other two large clouds were to the
north - in the general area of Mare Fecunditatis and Mare
Crisium though perhaps slightly further west and in contact with
the terminator? The effect was confirmed (independently) by 4
other observers using the same telescope. The telescope was
moved but the clouds remained in the same position over the
Moon. This report comes from The Astronomer Jan 2013 p 230.

On 2012 May 26 UT21:21 J. Moeller (Syracuse, NY, USA, using a
Konica Minolta DIMAGE Z5 digital camera, f/7.1, 1/250 sec
exposure, ISO-50, 69mm focal length, digital zoom x3) captured
a hand held image of the Moon in daylight. On the SW limb of
the dark side of the Moon a bright spot can be seen. This has
a brightness comparable to that of Mare Serenitatis. There is
also a fainter dark blurred marking further inside the dark side.

On 1977 Apr 29 at UT21:40-23:20 an unknown UK observer reported a TLP
in Gassendi crater. The following are reports by observers attempting
to confirm activity: J.W. Napper (Didcot, UK, 30cm reflector, x287,
Wratten 25 and 44a, conditions clear 5+) received a telephone alert
call at 22:00 but the sky was cloudy until 22:30. An initial look
revealed nothing unusual, then at 22:54 he observed a colour blink just
inside the north wall, appearing bright in red and normal in blue or
white light. No loss of detail seen and the effect lasted only 2
minutes. A sketch was made. However the observer stresses that the very
bad seeing casts some doubt on this observation. L. Fitton observed
using a 8.5" reflector, with Moon blink device at x200, seeing was I-
II. All areas negative, including Gassindi from 21:40-21:55 and again
22;00-22:25 and finally 22:50-23:30 negative. Mike Brown (Huntington,
York, UK, 30cm reflector, x220 and x350, seeing 3-4/5, and transparency
5/5) - observed from 22:00-23:25UT no colour seen, nor obsecuration,
all filters negative, despite seeing a lot of fine setail inside this
crater.
Herodotus 1966 Nov 24 UT 21:50 H.Hill (UK, 7.25" reflector,
x240), seeing 4-6/10, transparancy 4/5) sketched a central white
diffuse patch inside the floor of the crater, with a size of
about 1/7th the diameter of the crater. The eastern edge of the
white patch was encroached by the shadow of the eastern rim.

On 1993 Jun 02 at Ut 04:30-05:45 S. Beaumont (Cambridge, UK) saw that
the shadow of the Cobra's Head in Schroter's Valley was lighter and
more diffuse seen at user defined locations of C or B rim (these were
black versus medium gray for Cobra's Head). The TLP had vanished by
05:45UT. The Cameron 2006 catalog ID=462 and weight=3. The ALPO/BAA

On 1980 Jul 24 at UT22:10-22:55 P. Moore (Selsey, UK, 15" reflector,
x360 and x400) found an area just south east of the central peak (and
upto the wall) to be quite dark in blue light, but normal brightness in
red light or in white light. All other features were normal colour-

reflector, x200, x360, x624, atmospheric clarity good, seeing
III from 20:15-22:30, but the clouded out at 22:30, and from
23:15-01:15 seeing was IV-V with poor transparency) observed
(22:20-20:45 UT) variation in the SE corner of the
Aristarchus, namely the usual dark bands were alternating
light to dark, not in keeping with otyher crater features.
This effect was not linked to atmospheric turbulence. Also
projected image of bands beyond the crater W. wall were
repeatedly noted. The observer broke away from observing at
20:45UT to make a telephonealert call. At 20:55UT they noted
that the area between Vallis Schroteri and Herodotus seemed
very light/bright, also the E. exterior of the crater wall of
Herodotus. From 21:01-21:11 A slight blueness was seen to
extend from the NE corner of Aristarchus, along the exterior
rim, acrossand beyond Herodotus to the SW. A tgorough search
was made of many bright areas, both near the terminator and to
the E., but no blueness could be detected elsewhere. A slight
orange hue was noted along the E. limb of theMoon (Spurious
colour). From 21:18;22:30 Aristarchus seemed normal again, and
likewise the head of Vallis Schoteri too. The observer was
clouded out from 22:30-23:15and from 23:15-01:30 the seeing
was so appaling that no colour or projection of the bands
could be seen. A Moon Blink was used during the session, but
no colour was detected in this? Another observer, R.W. Rose
(Devon, UK) observed 21:20-21:30 but had IV seeing, and saw
nothing unusual, but commented that if TLP wactivity had been
taking place, then they would probably not have seen it. The
ALPO/BAA weight=1.
Aristarchus normal in red and blue filters however the
Cobra Head part of Schroter's Valley was brighter in blue.
Indeed it was very dull in red - Louderback says that this
was not surprising as the whole areas around Aristarchus is
brighter in blue. Louderback is an experienced observer
of the Aristarchus area of more than 10 years. Cameron 2006

On 2009 Jan 09 at UT 20:00 P. Brierley (UK) took a CCD image of the
Aristarchus area - P.Grego upon examining this comments that he thinks
that Schiaparelli crater looked "muted in brightness -- it is normally
quite bright to look at". Though Grego comments that it might have
something to do with the image processing aplied to the image. The
ALPO/BAA weight=1.
During an eclipse of the Moon the crater appeared normal until it
emerged from the shadow. In the north east the dark floor was
not its normal hue and two light areas appeared to join. The

6" reflector, Seing = 6/10) noticed blue on the north east corner of
Aristarchus and an orange glow on the south east wall. They detected no
movement or change in brightness. The observer used both eyes, to make
sure it was not an eye defect, and three filters: red Wratten 25, blue
Wratten 82 and Violet Wratten 47. Porter found that the colours faded
for a duration of 5 minutes and then returned. Their right eye gave a
good view and using their left eye they suspected that it was 0.5 steps
brighter than the remainder of the crater. The suspected colour
remained visible, even under moments of good seeing conditions. The
colour eventually faded over time and was eventually gone. Porter
reportd seein gcolour here on the following night. Apparently other
bright spots showed no colour. Fitton suggests that the filters used
confirm that the south east wass was definitely red in colour. The

Aristarchus 1970 Jan 24 UT 07:00? Observed by Thomas, Rogers,
Corralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moon blink)
"Bluing around the crater -- vis. in monitor but not photographe due to
clouds" NASA catalog weight=4 (high). NASA catalog ID #1233
Plato 1938 Jun 15 UTC 08:00 Observed by Haas? (New Mexico?, 12?"
reflector) "NW. end of floor had intensity I=2.0, but on 7/15/38, I=
3.7, conditions similar." NASA catalog weight=4 (high). NASA catalog ID
#439.
Mare Crisium 1962 Jul 19 UTC 09:48 Observed by Wildey & Pohn (Mt
Wilson, CA, USA, 60" reflector + Photometer) "Photometric meas. showed
change in brightness from Vmag=3.46 to V=3.07, where av. mag. for that
age=3.26, or a brightening of .58 mag." NASA catalog weight=5 (very
high). NASA catalog ID #763.
On 1965 May 18 at UT 03:00-03:30 Cragg (Mt Wilson?, CA, USA, 6"
refractor?) observed a TLP (no feature nor description given in
the Cameron 1978 catalog) on the Moon. The Cameron 1978 catalog ID=877
and weight=4. The ALPO/BAA weight=1.
On 1990 Jan 13 at UT 22:15-23:05 J. Pedler (Bristol, UK, seeing=III and
transparency=excellent, no spurious colour) detected a blue region on
the north of Aristarchus, varying in sharpness/diffuseness. The crater
rim in this region could not be descerned. Eleswhere the crater rim was
normal as too were other features. When a Moon blink device was used,
no colour blink was detected, however through the blue filter the
suspected area was bright and the crater rim indistinct. Whereas
through the red filter the area looked perfectly normal. At 22:30UT the
effect had vanished and everywhere was normal. The Cameron 2006 catalog
ID=388 and the weight=5. The ALPO/BAA weight=3.
On 1990 Jan 14 at UT 01:14-01:55 M.C. Cook (Frimley, UK, seeing=poor)
observed that Aristarchus did not appear normal for this illumination.
the northern half of Aristarchus was "2x>" than the southern half of
the crater. There were two white patches of apron material near to the
crater Herodotus that were 50% of the brightness of the southern half
of Aristarchus. Furthermore the southern half of Aristarchus had a
circle - "dull patch on inner S wall with a bright point shining
through it. (Bartlett's EWBS?)". The Cameron 2006 catalog ID=389 and
the weight=4. The ALPO/BAA weight=2.
Four bright spots seen in Mare Crisium. There was also peculiar
behaviour of the terminator. Source: Midlehurst 1968 catalog TLP ID=16.

Furnerius A 1983 Jan 02 UT 00:10 H. Hill (UK)
observed that this crater was piercingly bright,
which he thought was a bit unusual. ALPO/BAA weight=1.
Cleomedes 1991 Dec 23 UTC 22:50 Observed by Mizon (Colehill,
Dorset, UK, 8" f/6 reflector x216) "Oval or pear-shaped ashy
glow visible for 2 min, then vanished quite suddenly" - Ref.
personal communication received by BAA Lunar Section.
Peirce A (Swift=IAU name?) 1937 Dec 23 UTC 22:00 Observed by Wilkins
(England, UK, 12.5" reflector) "Obscuration on floor if crater. Crater
invis. (similar to #394, 396)." NASA catalog weight=4 (high). NASA

Aristarchus 1970 Jan 25 UT 07:00? Observed by Thomas, Rogers,
Corralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moon blink)
"Bluing around the crater -- vis. in monitor but not photographe due to
clouds" NASA catalog weight=4 (high). NASA catalog ID #1233
On 2002 May 30 at UT02:30-02:44 C. Brook (Plymouth, UK) suspected that
Aristarchus crater looked dimmer than normal. The ALPO/BAA weight=1.
On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9
refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP
in Macrobius. His report is as follows: "Blinked Macrobius with Wratten
Filters Blue 38A and Red 29. Macrobius became almost invisible through
the Blue 38A and essentially the same as in white light through the Red
29. The interior of the crater was completely in shadow. The only part
of the east wall that was visible was an apparent high point still in
the sun and seen as a bright point of light. This faded into darkness
before 13:56UT. No sign of any illumination of the east wall crater
interior or the interior of the west wall was seen during the
observation period. The outer west wall was a rough looking,
complicated mix of deep shadow and illuminated sunlit terrain." The
observer concluded that there was not a TLP - although he did get a
filter reaction, this may have been due to the different densities of
the filters? ALPO/BAA weight=2.
Observed by Dachille & daughter (Univ. Park, Pennsylvania, 10.5"
reflector, x75) "Flash -- then a brownish - red color patch. Alt. @
20deg. (MBMW has Oct. 12, but is 13th UT)". NASA catalog weight=5
(very good). NASA catalog ID #674.
On 1904 Aug 01 at 05:00? Pickering (Echo Mt., CA, USA) UT Plato:
"Bright hazy obj., 2" diam. on floor, Obs before & after were normal".
The Cameron 1978 catalog ID=318 and the weight=4. The ALPO/BAA
weight=3.
Aristarchus 1957 Oct 13 UT 07:00?$ W.Haas, according to the 1978
NASA Catalog is supposed to have seen a bright spot of light --
"explosion" in this crater. Confirmation of activity
in Aristarchus - Three independent observations within 4 hours.
Cameron 1978 catalog weight=5 and TLP ID No.=676. Private
comunication with Haas shows that he recorded nothing unusual
on the 12th or 13th. Therefore an ALPO/BAA weight of 1 has
been given until this matter is cleared up.
Fracastorius 2022 Apr 21 UT 01:35-02:12 A. Amorim (Brazil -
90mm f/10 refractor, 25 & 10mm eyepieces ) observed visually a
little bright spot near the centre of the otherwise completely
shadow filled crater. The bright spot was surrounded by a coma
effect. Clouds intervened but by 02:12 the spot was no longer
visible, just a thin patch of light close to the crater's
centre. Observations started when the Moon's altitude was 15
deg and ended when it was 23 deg above the horizon. ALPO/BAA
weight=1.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3"
refractor) observed that the south floor of Aristarchus was wellow -
"almost gold, spilled over S wall on ray toward Herodotus". Cameron
comments that Bartlett often reported a yellow floor but not a spill of
the colour over to the external ray. Cameron also comments that
Louderback's refractor would refract more in blue light than in yellow,
therefore she did not think that it was due to chromatic aberation. The
Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=2.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3"
refractor) found that all of Mons Piton was "unusually dark". Points D,
C (E and S resp), usually brightest points, but this time were not
bright. "Whole mt was as dark as W wall usually is at this time. In
violet filter Piton disappeared completely, but was a little brighter
in red filter and points D & G showed. Color not seen by eye. No albedo
measured. Suggests red event." Cameron rules out chromatic aberation
from Louderback's refractor. The Cameron 2006 catalog ID=431 and the
weight=3. The ALPO/BAA weight=1.
Callipus 1952 Sep 09 UT 21:00-21:20 Observed by Moore (England)
