APOD: Red Sprite Lightning with Aurora (2013 May 22) Image Credit & Copyright: Walter Lyons (FMA Research), WeatherVideoHD.TV http://apod.nasa.gov/apod/ap130522.html Explanation: What's that in the sky? It is a rarely seen form of lightning confirmed only about 25 years ago: a red sprite. Recent research has shown that following a powerful positive cloud-to-ground lightning strike, red sprites may start as 100-meter balls of ionized air that shoot down from about 80-km high at 10 percent the speed of light and are quickly followed by a group of upward streaking ionized balls. The above image, taken a few days ago above central South Dakota, USA, captured a bright red sprite, and is a candidate for the first color image ever recorded of a sprite and aurora together. Distant storm clouds cross the bottom of the image, while streaks of colorful aurora are visible in the background. Red sprites take only a fraction of a second to occur and are best seen when powerful thunderstorms are visible from the side. http://www.fma-research.com/ http://www.weathervideohd.tv/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130522 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0522
