More Amazing High Speed Images and Video of Sprite Lightning

When we first checked in with graduate student and astrophotographer Jason Ahrns earlier this month, he had the chance to be part of an observing campaign to try and photograph red sprite lightning from the air. Using a special airplane from the National Center for Atmospheric Research’s Aircraft Facility in Boulder, Colorado, Jason was part of a team that used high-speed video cameras and digital still cameras to learn more about this mysterious lightning. They flew over the central part of the US, such as over Colorado, Nebraska, and Oklahoma.

Named for the mythological sprites, which were known for being elusive, this lightning flashes quickly at high altitudes of 65-75 km (40-45 miles), but often as high as 90 km (55 miles) into the atmosphere. They are difficult to see from the ground, thus this airborne observing campaign.

Here are more images and video (some at 10,000 frames per second!) taken by Jason and his team:

Jason said on his blog, documenting the observing campaign, that “Most of what we saw were C-sprites, short for ‘Column sprites’ or ‘Columnar sprites’ – it just refers to their shape as tall, single columns.”

Sprites appear as luminous reddish-orange flashes, and sometimes look like jellyfish with “legs” that reach down into the clouds. Besides the columnar shapes, they also can be shaped like carrots and crowns, but why they take different shapes is unknown. They are thought to be triggered by the discharges of positive lightning between an underlying thundercloud and the ground. They were discovered by accident in 1989 when a researcher studying stars was calibrating a camera pointed at the distant atmosphere where sprites occur.
