    Largest Solar Radiation Storm Since December of 2006 in Progress

    An R2 (Moderate) radio blackout x-ray burst occurred Sunday evening from Region 1402. An Earth-directed Coronal Mass Ejection (CME) accompanied this flare and is potentially the fastest CME of the current solar cycle. Geomagnetic storming is a near certainty from this event, but pending preliminary analysis, no estimates are available yet for timing or strength of the storm. Initial model guidance shows this CME arriving around 900 am EST on Tuesday. The strongest Solar Radiation Storm will accompany this solar flare since December of 2006. The Radiation Storm reached S3 (Strong) levels as of 700 am EST today. Weak geomagnetic activity was noted on Sunday due to the January 19th eruption that sent a CME towards Earth. No impacts have been reported yet.
