Old Sunspot 1726 is proving to be a bit of a firecracker. The returning active region hiding just off the east limb produced a C9.0 solar flare at 23:00 UTC, followed by a stronger M3.9 event at 00:53 UTC.
The sunspot rotation will carry the active region back into Earth view within the next 24 hours.
Large Prominence Eruption off the southwest limb on Thursday afternoon. A Coronal Mass Ejection (CME) is visible in the latest STEREO Ahead COR2 imagery.
Because of the eruption location, the plasma cloud will be directed away from Earth.
