2014-09-12 18:05 UTC G2 (Moderate) Storming Underway
The second of the expected coronal mass ejections (CMEs) has arrived, and arrived in good agreement with the predicted arrival times. As expected, an initial looks shows this CME is stronger than the first. G2 (Moderate) storming is underway now and the forecast for G3 (Strong) storming on the 13thstill looks reasonable. The solar radiation storm that is in progress as a result of the eruption on September 10th peaked briefly, as it often does with the passage of the shock, but is currently below the S2 threshold and in decline.
