Bolts from the blue!

Not a big deal, but I've long been been intrigued by these aerial discharges* of static electricity. specially in summertime.
As you lovely friends can attest, there isn't much that can tear me away from the womanly charms seen on Tumblr -- the odd sports-car, an occasional dramatic landscape... and these freaky bolts from the blue!

More rarely, the inverse happens, the leader connects up from the ground, triggering a downward discharge... and then there is cloud-cloud lighting, etc. (Don't get me started on blue jets, upward superbolts, red sprites and other stuff...)
