2014-04-20 12:37 UTC  G2 (Moderate) Geomagnetic Storming Expected (Updated)

The first of the two expected coronal mass ejections (CMEs) has arrived, with the arrival of the second still expected in the near term.  These events, stemming from solar activity on the 17th and 18th, are expected to drive G2 (Moderate) geomagnetic storming on the 20th with G1 (Minor) storming continuing through the 21st.  Additionally, the S1 (Minor) radiation storm that occurred as a result of the eruption on the 18th is currently below the event threshold but may see an enhancement back over threshold with the arrival of these CMEs.  The regions that drove this activity are slowly rotating out of view, so continued activity is becoming less and less likely.  Updates here as this geomagnetic storm unfolds.

NOAA's Space Weather Prediction Center is pleased to debut the beta version of its new website.
