[00:00:00]Lightning can strike you from a cloud 40 km away under blue sky.

[00:00:05]These are bolt from the blue events, powerful positive lightning discharges that originate near the tops of thunderclouds. They travel horizontally through the atmosphere, sometimes tens of kilometers, before bending down to the ground in a single intense stroke.

[00:00:22]Though rare, they carry more current and last longer than typical negative flashes, making them disproportionately dangerous. To the observer, it looks like the sky itself glitched, firing electricity from nowhere.
