Geomagnetic activity is expected to be mostly quiet with possibilities of isolated unsettled conditions since the Earth is still within a fast solar wind stream linked to a coronal hole. Current readings of the solar wind speed measured by the ACE spacecraft are about 600 km/s. TODAY'S ESTIMATED ISN : 009, BASED ON 07 STATIONS.
