We don't expect C-flares to happen. The solar wind speed knows a revival and climbed up to 650 km/s. The cause is possibly the last part of the recurrent coronal hole which is ready to rotate over the westlimb. K_p went up to 6 last night. Geomagnetic conditions are calm now, we expect no disturbances the coming 48 hours. TODAY'S ESTIMATED ISN : 009, BASED ON 02 STATIONS.
