SPRITES OVER EUROPE: We all know what comes out of the bottom of a
thunderstorm: lightning. But do you know what comes out of the top? On

jellyfish-shaped 'sprites' flickering above a storm system in Austria.
Such upper atmospheric lightning is a form of space weather that is
being seen and photographed by increasing numbers of sky watchers.
