Rare Jet Spotted In Oklahoma

Yesterday, on Space Weather.com:

GIGANTIC JETS: Think of them as sprites on steroids: Gigantic Jets are lightning-like discharges that spring from the top of thunderstorms, reaching all the way from the thunderhead to the ionosphere 50+ miles overhead. They're enormous and powerful.

You've never seen one? "Gigantic Jets are very rare," explains atmospheric scientist and Jet-expert Oscar van der Velde of the Université Paul Sabatier's Laboratoire d’Aérologie in Toulouse, France. "The first one was discovered in 2001 by Dr. Victor Pasko in Puerto Rico. Since then fewer than 30 jets have been recorded--mostly over open ocean and on only two occasions over land."

That's why researchers are excited by the events of Aug. 20th. On that night, amateur astronomer Richard Smedley of Broken Arrow, Oklahoma, was hunting for meteors using a low light video camera when he caught two Gigantic Jets instead (view the 4.5 MB video).

"They were much brighter than a typical meteor--more like a fireball," says Smedley. To appreciate the size of these things, consider the following: "They came from a thunderstorm more than 100 miles away in Missouri: map." This means the Jets were about 48 miles tall measured upward from the top of the thundercloud.
