A magnetic filament snaking around the sun's SE 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 the above picture during the early hours of Dec 6, 2010.
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. Further updates will be posted as warranted.
