The M-Class eruption will have a strong coronal mass ejection associated and may have earth-bound or earth directed components as the region was close to being in an earth-facing position at the time of eruption.
Latest images show a strong Coronal Mass Ejection(CME) heading earths way, it is estimated that impact on earths magnetic field should occur late April 13th and a possible G2 or G3 Class Geomagnetic storm sometime during April 14th.
