We expect this CME to arrive at earth later today. In STEREO/A COR2 images, this CME appeared to be not directed straight to earth, but more upwards. Unsettled geomagnetic conditions are possible, also due to a coronal hole that will be crossing the central meridian in the coming days. As for solar activity, C-class flares are still possible. TODAY'S ESTIMATED ISN : 020, BASED ON 06 STATIONS.
