Plasma mega-snake on the sun!
This just in from our “Solar Dynamics Observatory is blowing my mind” department — and SpaceWeather.com: a plasma mega-snake on the sun.
A magnetic filament snaking around the sun’s southeast limb just keeps getting longer. The portion visible today stretches more than 700,000 km–a full solar radius. NASA’s Solar Dynamics Observatory took this picture during the early hours of Dec. 6th. The STEREO-B spacecraft, stationed over the sun’s eastern horizon, saw this filament coming last week. So far the massive structure has hovered quietly above the stellar surface, but now it is showing signs of instability. Long filaments like this one have been known to collapse with explosive results when they hit the stellar surface below. Stay tuned for action.
