Bulletin

Solar activity remains low with only few C-class flares reported during the last 24 hours. The strongest reported flare was a C3.3 flare on March 25 (peak at 16:45 UT) originating from the Catania sunspot group 13 (NOAA AR 2305). This active region maintains the beta-gamma-delta configuration of its photospehric magnetic field and therefore still has the possibility for producing C-class and M-class flares in the course of coming hours. No Earth directed CMEs were observed during last 24 hours. The solar wind speed decreased to the value of about 450 km/s and the interplanetary magnetic field is stable with the magnitude of about 6nT. The geomagnetic conditions are at the moment quiet, we expect quiet to unsettled geomagnetic conditions in the following 24 hours.

Today's estimated international sunspot number (ISN): 079, based on 08 stations.
