DARK FILAMENT: For the 4th day in a row, the Solar and Heliospheric Observatory (SOHO) is tracking a dark magnetic filament curling over the sun's northeastern limb. The massive, plasma-filled filament has been remarkably stable since SOHO first spotted it on March 5th. However, filaments like this have been known to collapse. If this one does and hits the stellar surface, the impact could produce a powerful Hyder flare.
