Sprite Season Begins [HD]
Sprite Season Begins: The first sprites of summer are starting to appear in the skies of North America. The strange thing is, summer is almost three months away. "Sprite season is beginning early this year," says Thomas Ashcraft, who photographed these specimens last night from his observatory in New Mexico:
"At precisely two minutes and twenty-six seconds after midnight March 30, 2012 there was an incredibly powerful bolt of lightning in the vicinity of Woodward, Oklahoma that spawned these red sprites," says Ashcraft. "I could see them from two states away!" He also recorded VLF and shortwave radio emissions from the cluster, which you can hear as the soundtrack to this video.
Sprites are electrical discharges that come out of the top of thunderclouds, opposite ordinary lightning bolts which plunge toward Earth. Sprites can tower as high as 90 km above ground. That makes them a form of space weather as they overlap the zone of auroras, meteors, and noctilucent clouds.
Because they are associated with lightning, sprites are most often seen in summer months, "but in the past few days sprites have been reported in Texas (particularly near the Mexican border) as well as here in New Mexico," notes Ashcraft.
So if there's lightning where you live, be alert for sprites.
Sound of the sprites.
