Hi,

One of my high speed pictures caught something unusual.  It was just 
a normal power arc:

But when I pumped up the brightness and contrast to see the lead up 
pulses, I see there is like a "cloud" of ions or something after the 
strike (time is increasing upward).  1MB picture since I did not want 
to loose detail.

There is a little air streamer super imposed on the lower image while 
the shutter was open.  Note the cloud that almost looks like smoke 
from the main strike.  They are fairly bright and fuzzy so I assume 
some type of ionized cloud or something.

A similar strike does not show the effect:

A blank frame seems like the situation is clear of abnormalities:

So I think the cloud or whatever was real.
