Fine Structure

Wow, this is just impressive. A couple bolts of lightning captured with a high-speed camera.

A couple interesting things to watch for: the big strike on the left gets really bright when it first finds the ground, then it just sticks around for a while as it discharges. The more snake-like one on the right keeps growing and branching until it (presumably, we don't see it) finds the ground. I wonder what the difference is between the slowly growing branches and the very quick short bursts of "sparks" that are more common.

All-in-all, probably no more than a second or two in full non-expanded time!
