Hi Frank and List,

The Leonids are among the fastest of all meteors. They plunge into the
Earth's upper atmosphere at about 72 km/s - multiple times the speed
of a rifle bullet (!)

These are associated with a previously unknown dust band which
has been shepherded into a narrow stream by Jupiter's gravity.

Best wishes,

Bernd (still ducking)
