Long duration C2 solar flare erupted from Region 1690

A long duration C-class solar flare erupted from Region 1690 on March 12, 2013. The event started at 10:17, peaked ad 11:06 as C2.0 flare and ended at 12:25 UTC. A Coronal Mass Ejection (CME) was produced. Region 1690 still has Alpha magnetic configuration, but its

Huge solar prominence erupted off the southwestern limb - non Earth directed CME

A huge magnetic filament erupted off the Sun's southwestern limb during the early hours of February 27, 2013. Most of the plasma looks to be headed away from the Earth though. On the Earth side of the Sun, Active Region 1682 developed a 'beta-gamma'
