Geoeffective region erupts with moderately strong M1.0 solar flare


Moderately strong solar flare measuring M1.0 erupted from Region 2035 (S17E18, Fkc/beta-gamma) on April 16, 2014. This event started at 19:54, peaked at 19:59 and ended at 20:04 UTC. A Type II Radio Emission with estimated velocity of 1071 km/s was associated.

Type II emissions occur in association with eruptions on the sun and typically indicate a Coronal Mass Ejection (CME) is associated with a flare event.

This region produced multiple C-class events in last 32 hours. It is continually exhibiting growth and is located almost at the center of the disk. 


Based on limited SOHO LASCO C2/C3 coronagraph and STEREO A and B images, initial analysis indicated an Earth-directed CME with a preliminary speed of 642 km/s. Current Enlil run indicates a potential arrival at Earth on April 19 at approximately 18:00 UTC. Additional analysis will be accomplished with possible adjustments to timing of arrival times as additional data becomes available.
