Timelapse: Sprites, Gravity Waves and Airglow

Look! Fast! Sprite lightning occurs only at high altitudes above thunderstorms, only last for a thousandth of a second and emit light in the red portion of the visible spectrum, so they are really difficult to see. But one of our favorite astrophotographers and timelapse artists, Randy Halverson captured sprites during a recent thunderstorm in South Dakota. But wait, there’s more!

In his timelapse video, above, you’ll also see some faint aurora as well as green airglow being rippled by gravity waves.

See some imagery from the storm, below:

Simply Breathtaking Night Sky Timelapse: “Huelux” by Randy Halverson

Regular readers of Universe Today will be well-acquainted with the photography and timelapse work of Randy Halverson. He’s just released his latest timelapse and in a word, it is breathtaking. Aurora, thunderstorms — sometimes both at once — and, of course, stunning views of the night sky.

Randy shot the footage during April-November 2013 in South Dakota, Wyoming and Utah. “The weather in 2013 made it difficult for me to get some of the shots I wanted,” Randy said on Vimeo. “There were many times I planned to shoot the Milky Way or Aurora, and the clouds would roll in. But that also allowed me to get more night storm timelapse than I have any other year.”

He added that the aurora sometimes appeared without warning. In the video, be on the lookout for slow and fast moving satellites, quick meteors and slower moving airplanes. “The meteors are hard to see in timelapse, but you may see a quick flash because they only last one frame,” he said. “If you see a light moving across the sky, it is either an airplane or satellite, not a meteor.”

Sit back, put this on full screen and full sound and take a well-deserved break from your day!

Thanks once more to Randy Halverson for continuing to share his handiwork! Find out more about this timelapse at Randy’s website, Dakotalapse.
