Bulletin
Solar Activity has been low. No C flares or higher detected. C flaring and potentially an M flare is still possible from AR Catania 95 (NOAA 11678) on the West limb and therefore flaring from this region can possibly generate proton events. Geomagnetic activity has been quiet and is expected to remain so for the next 48h.
Today's estimated international sunspot number (ISN): 043, based on 06 stations.Solar indices for 21 Feb 2013
