I'm not talking about the blue spark that clearly comes from the top of the coil and impacts the ground rail. (Yes I've noted this happens occasionally with the current setup, but not too often, from observation.) I'm talking about the much dimmer "spark" which I have supplied several still shots from the video and numbered it's motion from above the toroid down to the toroid, then back up, which happens to coincide with the blue spark hitting the ground fence. Then in a second video it shows up again under
same condition - that time
actually goes between the toroid and the blue spark as it hits the ground fence. The spark artifact I speak of is almost reddish in color, and much dimmer. See the pics again.

No, have no sharp edged object at the top of the secondary.

Actually the bottom of that toroid is only 5.5"
above the secondary top coil. Additionally that
metal bowl underneath acts as a semi-sphere on the
bottom mounted very near the top of the secondary.
Someone else also mentioned the dim reddish spark
artifact could be something related to the video,
but it's showing up in two different videos, the
second of which is clearly going from the toroid
to the blue spark as it hits the ground rail, seems
to me to indicate something more?
Here's a composite animation of the still pics I
previously supplied - maybe it shows better the
strange "spark" (not the blue one) coming down
from above the toroid (during the rail strike).
The last frame is from a second video which also
shows that spark coming from the toroid (again
not the blue spark). The reddish dim spark, not
the blue one. It just coincides with the
one striking the rail, in both videos where it
