A sector boundary crossing caused unsettled geomagnetic conditions over the past hours. However, the solar wind speed remains limited below 400km/s and is already declining. We thus forecast a return to mostly quiet geomagnetic conditions today and for the next two days of the forecast period. TODAY'S ESTIMATED ISN : 015, BASED ON 15 STATIONS.
