Hi Bert,

Positive lightning also seems to be associated with sprites.

This monster bolt was almost certainly positive lightning from the top of a nearby storm. These lightning strikes are especially nasty not only because they may pack 10X the current, and the heavier current flows for much longer than regular [negative] lightning, but they have been known to propagate over 10 miles _horizontally_ from a storm! They are the fabled "bolt from the blue" - positive lightning has been known to come from a storm on the other side of small mountains. The positive lightning goes OVER the mountains where it can strike a hapless individual sunning themselves on a beach on the other side of the mountains.

The text that goes with this picture (from the Australian amateur lightning photographer who took it) is on this page:

Best regards,

Bert
