The Sun Online and solar activity. September 11, 2014

The X1.6 flare from 10 September was associated with an asymmetric full halo coronal mass ejection (CME). It was first seen by SOHO/LASCO at 18:00UT and had an average plane-of-the-sky speed of about 800 km/s. The CME is expected to arrive at Earth on 12 September around 21:00UT (+/-12
hours). It is not expected to interact with a previous halo CME from 9 September. Major to severe geomagnetic storming is expected, pending the orientation of the magnetic field of the plasma cloud.
Starting around 21:00UT (10 September), a gradual increase in proton flux has been observed. It is currently above the event threshold near 30 pfu. This is only a minor radiation event with limited consequences for HF communication in the polar regions.
