Valószinüleg ugyanerről irtam a hétfői levelemben:

Sziasztok

A kovetkezo erdekes hirt talaltam az IOTA honlapjan:


Lunar impact confirmed in November 18th video record


     Brian Cudnik, Houston, Texas, saw a brief flash near the center
of the Moon´s dark side near the edge at about 4h 46m 20s U.T.
November 18. Observing with his 36cm telescope, he estimated that
the flash, taking a fraction of a second, was at least as bright as
nearby 4th-mag. psi1 Aqr. The observation was confirmed in a video
recording made by David Dunham using a 13cm telescope at Mount Airy,
Maryland. The event was near the lunar equator 1.7´ from the Moon´s
edge. The flash, timed from the videotape at 4h 46m 15s, is visible
in only two video frames, the first at about 3rd magnitude and the
second at about 8th magnitude. The images can be viewed at
http://iota.jhuapl.edu Dunham notes that the object was probably a
Leonid since the peak of this year´s display was at 2h UT as seen
from the Earth. The trailing Moon would arrive at the same solar
longitude about 3h later, near the time of the observed impact.
Dunham also recorded 5 lunar occultations of 8th-magnitude stars an
hour before the impact. Analysis of those images and of the impact
images will permit a reasonably good determination of the brightness
and location of the impact flash. Anyone else who was recording the
dark side of the Moon at the above time should check their data and
report their results to Dunham at david.dunham@jhuapl.edu.

     Dunham, president of IOTA, believes this is the first confirmed
lunar impact observation. A probable lunar meteor impact was
photographed on 1953 November 15 by Dr. Leon Stuart; see
