At this point, the coil aready did what it could do. The energy
trapped in the self-capacitance of the secondary coil is really
not immediately available, and will usually oscillate until 
dissipated. 
The simple lumped model canīt predict what happens next in
this case. A model including extra capacitances along the
secondary coil is required. Maybe those models that we discussed
some time ago, in a version (surely possible) including the
primary circuit.
But when recing sparks appear, is the coil producing streamers,
or in this case, sparks to ground?
