STEREO spies spectacular eruptive prominence in extreme UV

Via the Professor, Nasa’s STEREO (Ahead) spacecraft captured this stunning footage of a spectacular eruptive prominence in extreme UV light as it blasted away from the Sun (Apr. 12-13, 2010). The prominence appears to reach about 50 million 500,000 miles, halfway across the Sun. [Correction via Gizmodo] The video clip shows about 19 hours of activity. Video credit: Nasa/STEREO.

    So Pete are we in for a good summer or not.

    I know you’re just repeating what they said, but something doesn’t compute. The circumference of the sun is about 2 1/2 million miles so half way round is definitely not 50 million miles.

    Yes, Joe.

    Someone at Nasa got their sums wrong.

    I’ve added the correction from Gizmodo.
