Hi Matt and all

What you saw precisely describes the sparks  I saw at low power.  I would be
interested in any photography of them. There have been many  most
interesting responses to the question of sparks being bright in the middle.
I think that high speed photography techniques might provide some answers.
Back in about 1959 or 60 I went to a symposium on Photography and Lenses in
Los Angeles and saw some fascinating motion pictures of bullets and other
high speed projectiles. They were astonishing to say the least. (I did
manage a hand shake with Wernher von Braun who was there at the time.)  The
photo technology is there to take the pictures. The  only problem is
getting funding to do it as one of the responses to this phenomena
indicated.

Cheers   Chuck
