Geomagnetic activity is expected to be unsettled to active with possibility of isolated minor storm conditions due to the influence of a recurrent fast solar wind stream. Current readings of the solar wind speed measured by the ACE spacecraft are about 600 km/s. TODAY'S ESTIMATED ISN : 008, BASED ON 09 STATIONS.
