Solar wind parameters display a shock at 9:52UTC. Solar wind speed jumped from 370 km/s to 410 km/s and total magnetic field jumped from 6nT to 14nT. This shock is most likely associated to the halo CME from 20:38UTC, February 17 following the X2 flare that peaked at 20:16UTC. The CME was mainly directed towards the North East and we are expecting to only see a glancing blow. The north-south component of the interplanetary magnetic field is currently directed northward, and with the limited velocity, geomagnetic impact is currently estimated to remain at active levels. Minor storm levels could be reached if the magnetic field becomes oriented towards the south.
