Bart, I noticed the large amount of what I remember being called, "Pixel
noise". Is this because the camera can capture ions not visible to the
eye, or some other reason due to the cameras capabilities?

About the vertical streamer being influenced magnetically in some way.
This was also my guess. Except my thinking was it reached the end of the
coils strongest magnetic field, and decided to follow the edge of it.
Your guess seems more likely to be the real cause of the vertical
streamer though.

Is it a good guess that the streamers follow an outward path because this
is the direction of the electromagnetic force?

Another question. A Tesla Coil emitting streamers into the air is still a
complete circuit isn't it? The ions are following an invisible path to
the ground because of t! he secondaries ground connection. Or am I wrong?

      Hi Matt,



      Here's an image I raised gamma to 2.4 and adjusted the
      color-balance to

      identify hot stops of the arc at. I cropped the left arcing
      side of the

      picture to reduce ! the size of the image.

      Note that there is a hot spot which the small vertical
      streamer appears

      to have resided from. Probably not a previous arc. Just a
      chosen

      direction for the streamer itself. There's really a lot of
      neat things

      going on in our streamers. This pic pretty much gives a good
      indication

      of the overall situation. Note the hot spot at the toroid.
      Follow those

      streamers to the second hot spot. You can see from the
      streamers

      emanating from that 2nd hot spot that the 3rd hot spot was
      developed

      from the 2nd hot spot. I expect that little vertical streamer
      was

      influenced by the 2nd hot spots magnetic fields (just a
      theory).



      Things like this occur with sparks. It's great that you
      noticed it and

      captured the subtle difference on image.



      Our coils are often termed disruptive coils with a chaotic
      output.

      Although they are disruptive coils, the streamer propaga!
      tion has a

      definite physics which governs the path the streamer travels,
      and part

      of those physics is the tip of the streamer itself. As seen
      in natural

      God created lightning and even our coils, streamers can
      change direction

      in an instance. But isn't it interesting that the change in
      path is

      really not all that great. Sure it diverts from time to time,
      but the

      general direction is "away" from the point of origin. I've
      never seen an

      arc in natural lightning or in man made device travel outward
      and then

      back near it's origin. If high power and highly mistuned
      coils, they do

      sometimes come close by hitting about 1/3 down the coil
      itself, but

      that's a different problem (I once had).



      Take care,

      Bart
