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
ID=323 and weight=2. the ALPO/BAA weight=2.
Posidonius 1849 Feb 11 UT 02:00? Observed by Schmidt (Athens, Greece,

1821." NASA catalog weight=4 (high). NASA catalog ID #128. ALPO/BAA
weight=3.

0648. At 0650 color gone. Seen again at 0658 but not so pronounced.
Faded out at 0700, obs. terminated at 0725. (Haas thinks it might have
been atm. dispersion at such low alt. of 12-17 deg)." NASA catalog
weight=1. NASA catalog ID #1038. ALPO/BAA weight=1.

On 1981 Dec 16 at UT 17:45 B.W. Chapman, Kingston-Upon-Thames,
UK, 11.5cm refractor, seeing II, trasnparency Fair) found the
west inner ridge lighter in red, and so to the east and south-
west floor. The ALPO/BAA weight=1.

Near Calippus 1973 Jan 25 UT 19:20-19:30 Observed by Frank
(E.Pepperell, Massachusetts, USA, 6" reflector, x100, S=G) "Bright spot

6deg, SWBS now smaller but still 9deg. S.floor still granulated & now

On 1994 Jan 04 at UT21:00 J. Nibbering (Rosendaal, Netherlands)
obtained a photograph that shows a large crescent of light centred on
Tycho crater, but includes also: Lilius, but not to Clavius. Cameron
suspects strongly that it was caused by camera lens flare. The Cameron
2006 catalog ID=471 and the weight=5. The ALPO/BAA weight=1.
On 2009 Jun 16 at UT 03:20-03:40 P. Morgan (UK, 30.5cm reflector, x400,
seeing=6/10 and transparency=5/5) observed a large diffuse ashen-like
effect over the shadow filled floor of Plato. The effect was lighter
towards the south. Observer checked the effect with both left and right
eyes and it remained the same. Unusually no shadow spires from rim
moutain peaks were seen. A check for colour in the region effected
revealed none. As time progressed, terrestrial twilight encroached. A
sketch was made. The ALPO/BAA weight=1.
Aristarchus 1976 Nov 16 UT 06:15 Observed by Bartlett (Baltimore, MD,
USA, 3" refractor, 54-200x, S=4, T=5) "Crater very dull except EWBS=
9deg & large. W.glacis=5deg & inner E.wall 6deg. Floor is dull 5deg,
c.p.=10 deg. SWBS has disappeared. No viol. anywhere" NASA catalog
weight=4 (high). NASA catalog ID #1460.
On 1821 July 25 at UT 03:30 Gruithuisen (Munich, Germany) observed,
near Aristarchus, some brilliant flashing spots on the Earthlit side of
the Moon. These disappeared after a short while then re-appeared. The
Cameron 1978 catalog ID=90 and weight=4. The ALPo/BAA weight=3.
