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

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

On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector,
x300) using an English Moonblink device found colour on the south west
part of the floor. Note that for the times given by Cameron, the Moon
was below the horizon from California - so possibly these are local
times and these times need to be correctly converted into UT? The
Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.
Gassendi. 2023 May 02 UT 01:35-02:23. J. Albert (Lake Worth,
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.
Aristarchus 1880 Jan 23 UT 20:00? Observed by Trouvelot

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

On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in
Gassendi - some obsevers detected colour, others did not. P. Moore did
not notice anything unsual earlier at 18:50-19:00, though his seeing
was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing
was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also
reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did
however notice a small reddish spot to west of central ridge, but by
20:30UT the colour was less obvious, but the spot was back again at
20:45, but not easily seen at 21:00 and gone completely by 21:45UT.
N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red
patches on the floor between 20:54 and 21:31UT. A BAA Lunar Section

On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK,
12" reflector, x200, seeing=II) noticed in the area south east of
Manilius that it was brighter in red light than in blue light at
20:15UT whereas 1 minute later it was the same brightness in each
filter. The effect reappeared at 20:21UT and was particularly strong at
20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was
of high reflectivity in white light and was bright in red at 21:15UT,
thougjh the south east area stopped giving a colour reaction at
21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT
however at 23:55UT it was surrounded by a transient white ring that
varied in visibility in an irregular way. Foley found Manilius B had a
vivid blue interior and in blue light the ring was black. and not at
all seen in red or white light. The CED brightness measurement varied
from 1.9 to 2.4. All other regions observed were normal in brightness.
Violet was seen on the west wall of Aristarchus though. M.Price
(Camberley, UK) found a possible blink in Manilius B but was observing
under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5.

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.
Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi

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=

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.

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 1979 Oct 04 at UT21:05-23:40 P.W. Foley (Kent, UK, 12" reflector,
x360, seeing=II) detected colour in Aristarchus (and also in Bullialdus
- there was a TLP alert at this time for Bullialdus) but nowehere else
on the Moon. Aristarchus had a CED brightness value of 3.8 at 21:05

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

On 2000 Jan 21 UT04:40 G. Emersen (Golden, CO, USA, 30cm focal length
lens with Wratten 25 ref filter) took 43 CCD images of the eclipse of
the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively
bright spot appeared in the southern part of Mare Fecunditatis. The
spot looks sharper than the rest of the Moon and so might be a cosmic
ray? CCD images taken from Washington D.C. by A.C. Cook at this time,
do not show this spot, however exposures were at intervals of 0.25 sec
and so might have missed this spot if it happened during image readout.

(Guilford, UK, binoculars), Foley (Dartford, Kent, UK, 12" reflector
and photographs), and McKay (Kingston, England, UK, 6" reflector, x48)
observed the following in Aristarchus during a lunar eclipse: "It
appeared much fainter than ever before seen in ecl. by Moore. Fainter
than Proc., Cop., & Tycho. Others rated brightness in order-- Hell,
Stevinus, Furnerius, proc.; & Proc., Tycho, Hell, Aris. Photos
confirmed dimness of it. For some observers it became invis. at S=II
(good). Good ranked at least 4 other craters brighter than Aris. & that
at 2035h it dimmed. Earthshine cond. extraordinarily good. Peters, at
S=IV (fair?) rated Aris. brightest". At 23:50UT LeCroy Jr and Sr
(Springfield, VA, 4.5" reflector, S=7) observed four glowing spots on
the Moon during a lunar eclipse (including Aristarchus). At 23:50UT
Aristarchus was an oval shape with no details seen. It had a ray
extending from the south west rim (normal). The north rim was slightly
blue and the south west rim very very slightly red. At 23:55UT it was
clearing and details showed. At 00:02UT it was clear. Sketches were
provided. Cameron comments that the colours fit Fitton's predictions on
spectral dispersion in our atmosphere from atmospheric inversions. The
brightness measued was 10+ and normal should be 9, and the plain is
4.5. The Moon's altitude at the LeCroy site was 45 deg. The Cameron

On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by N. Hazel
(Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max,
with 2x teleconverter, at f9, 1/320 sec, ISO 400 – tripod
mounted, mirror up), A series of images were taken. The 21:06 one
showed a grey column cutting across the central floor of the
crater from the west and then bisecting the eastern rim. All
detail inside is completely invisble. Some (but not all) of the
other images showed a more blurred view of this feature. It's
possible that this was a seeing ripple effect, or just the
natural appearance of shadings on the Moon at this time, however
for now this will be given an ALPO/BAA weight of 1.
On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade
2045 reflector, x40, seeing=turbulent) detected flashes coming from
just north of the centre of Mare Tranquilitatis. Some of these flashes
were of a duration of seconds whilst others were several minutes.
Altogether ~20 flashes were seen, and not in the same place. "5 small
star-like points could be located - and there were lots of craterlets".
The spots were "lined up E-W at N of 10 deg latitude." Colour was not
visible on these nor variations. Apparently the observer had seen this
type of TLP before but had not reported them. The Cameron 2006 catalog

south-east rim with the "Spur". Apparently Chapman (Kent, UK) detected
it easily. At 01:33UT the colour was barely visible. No TLP alert was
issued because the souther edge of Mons Pico also exhibited a hint of
colour, and anyway the seeing conditions were poor. Despite this no
other features revealed colour. The Cameron 2006 catalog ID=446 and the
