Long Duration M3.3 Solar Flare August 17, 2013

An Long duration M-Class Solar Flare observed from active region 11818 in the southern hemisphere of the solar corona. Peaking to M3.3 at 18:23 UTC August 17th. Associated with this blast was a 10cm radio burst (Ten Flare) measuring to 150 solar flux units. This eruption was slightly ahead of an earth facing position and the resulting Coronal Mass Ejection (CME) does appear to have a strong earthbound component due to the complexity of the blast. Early assessment of the CME indicates impact on earths magnetic field late August 21st where geomagnetic storms will be possible.
