SOLAR FILAMENT EXPLODES, HURLS CME: On April 9th, a dark filament of magnetism on the sun rose up and hurled a portion of itself into space.  NASA's Solar Dynamics Observatory recorded the eruption:
Flying debris from the filament formed the core of a coronal mass ejection (CME).  At first it appeared that the CME would miss Earth, but a new analysis by NOAA forecasters suggests that a glancing glow is possible on April 15th.  G1-class geomagnetic storms are possible when the CME arrives this weekend.
