Check out the archives from Aug and Sept 2002 on pupman-dot-com.
We went through this whole topic pretty extensively.

Question - was there always lightning when the ball formed? A recent article
in
Science News by some professor from New Zealand claims it requires a
lightneing
stirke to form and is the result of silicon vapors. Your observation seem to
refute this theory. 

I have a copy of a magazine article written in the 1920's by a person who
was
running an Ouden coil that produced ball lightning on two occasions. Both
times
the pea sized ball floated about and then hit the fellow's brother with some
significant results. This was published in the TCBA newsletter. 

In  one of the report tapes by Richard Hull, some fellows in California
reported about a ball lightning that formed in a rotory spark gap which was
made from a metal fan blade. While the actual event was not on the tape the
fellows stated that the ball floated around for a few seconds then hit the
power outlet and shorted it. 

It would be nice to be able to study this stuff if it could be reproduced on
demand.
