Yes I have noticed this effect.  If you have a small flourescent tube
about 12" long then place it on the primary of your coil so that it lays
across several turns, and run the coil.   You should get flash over 
between the turns.   On my coil I get 2" arcs that run along the surface
of the glass.   Don't run for too long if you want to keep the tube.
