Bulletin

Solar activity is expected to remain at low levels for the next 48 hours, with only a small chance for an isolated C flare from NOAA AR 1708. Geomagnetic conditions are currently active at planetary levels (Kp=4), as the Earth is still under the influence of a coronal hole. Unsettled to isolated periods of active conditions are still possible today, but we expect the geomagnetic activity to return to quiet levels by March 30.

Today's estimated international sunspot number (ISN): 049, based on 06 stations.
