Impulsive solar flare measuring M1.2 erupted from AR 1654

A moderate but impulsive M-class solar flare measuring M1.2 erupted from big Active Region 1654 on January 11, 2013 at 09:11 UTC. A Coronal Mass Ejection (CME) is expected as ejecta has been observed exiting the blast area.  A Type II and Type IV Radio Emissions were associated with the event. AR 1654 is rotating into more geoeffective position and has beta-gamma magnetic configuration capable of producing more M-class flares. Watch out for this region in the coming days.

The event started at 08:43, peaked at 09:11 and ended at 09:17 UTC.

Serial Number: 399
Issue Time: 2013 Jan 11 1006 UTC

ALERT: Type IV Radio Emission
Begin Time: 2013 Jan 11 0930 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.
