Charge stored in the capacitance between primary and secondary?
Possible if the primary circuit is insulated from the ground,
but this is a very small capacitance. 
The most probable origin of this charge is from ionized air 
around the coil depositing charges over the insulation that 
covers the grounded secondary coil.
