A 'LIGHTNING BOLT' ON THE SUN: Imagine a bolt of lightning half-a-million kilometers long. Actually, no need to imagine. Here it is:

This enormous plasma discharge zig-zagged through the sun's atmosphere yesterday, Jan. 19th, briefly connecting two sunspots AR3192 and AR3190 with a 500,000 km-long current dwarfing any terrestrial lightning.

The upshot of the bolt was ... nothing. No CME or other debris emerged from the area. Currents and hot plasma were contained inside the crooked channel. Maybe next time.
