Hi Bjrn,
I'm not so sure this was a Leonid. It could be that the aerodynamic shape of
the two pieces caused the spiral motion. Leonids are too friable to
withstand such forces (chi = 0.37). It was probably something more
substantial. The fact that it appeared to come from the Leonid radiant
(which is what I assume you mean) may just be coincidence.
Still, I would like to include it on my Anomalous Meteor Page at
www.ticetboo.demon.co.uk/amp.htm - if that is OK with you?
Regards,
Phil Bagnall

Definitely one of the many Leonids at that time, coming right
from the radiant point. But this one was not only a very bright
meteor, it also had split in two. Added to that, each of the
parts rotated at a fast rate, so as to make a close double
helix.
