Bulletin

Solar activity remains to be low, with no flares above the B-level reported since September 03. We expect this low solar activity to persist with possibility of only an isolated C-class flares in the coming hours. No Earth directed CMEs were observed in the last 24 hours.

The Earth is still inside the fast flow with the solar wind speed of about 500 km/s. The interplanetary magnetic field magnitude is rather stable having the value of about 7 nT. The geomagnetic conditions are currently quiet to unsettled and we expect it to remain so in the coming hours.

Today's estimated international sunspot number (ISN): 043, based on 18 stations.
