Scott,

My gap is a synchronous rotary running at 240BPS, located in the base of the coil.

Here is a picture taken from the opposite direction the same night:

I'm 99.9% certain the "phenomenon" is due to a street light, along with a long exposure time, accidental flash and camera movement.  See my other message with another similar picture from the same session.

Curt.

Curt -

Here's a possible explanation  for the brightest "traces" consisting of 
multiple linked bright spots.

1. It looks like this exposure had a an effective "shutter speed" of 1-3 
seconds, and include an "on camera" flash event. The toroids are in-focus, 
and don't show any significant "ghost images" from camera movement 
before/after the flash.

2.The two bright yellow traces clearly pass in front of the top toroid, and 
are therefore not artifacts of some light source (streetlight, etc) far 
behind the coil.

3. These traces don't look anything like the internal reflections caused by 
a bright off-axis light source bouncing off multiple lens surfaces in a 
compound air-spaced lens (like a zoom lens).

4. The paths of these traces are relatively smooth and continuous, without 
any sudden sharp angular jogs or divergence from a "smooth" trajectory.

5. One notable aspect of the traces are the regularly spaced dots of light, 
slightly smeared, along the axis of the trace.

6. Where is your spark gap located, what type of gap is it (static, rotary, 
etc) and do you know what the break rate is?

7. I think the evidence suggests that these traces were caused by  insects 
(moths, etc) flying in the vicinity of the coil, illuminated by the intense, 
regular flashes of light from the spark gap. If you know the break rate of 
your spark gap, and have a higher-resolution copy of the image so you can 
count the dots in an estimated distance, you can calculate the approximate 
velocity of the insect and see if it "fits" the flying insect hypothesis. 
The increasing distance between dots as the "object" got closer to the 
camera fits the hypothesis.

Regards,
Scott Hanson
