Bulletin

Solar activity was very low during the last 24 hours, with a soft Xray background in the low B level. There is a slight risk for an isolated C class flare from NOAA AR 1670, but the next 48 hours are expected to be mostly quiet in terms of flaring activity. Geomagnetic activity is expected to be low to unsettled for the next 48 hours, with the expected arrival, by mid-day, Feb. 12, of the CME of Feb. 9. Unsettled activity, at most, is foreseen from this event, as the bulk of the CME is passing northward of the Earth. Currently, quiet conditions are observed by the ACE spacecraft.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 035, gebaseerd op 03 stations.
