Bulletin

Solar flaring activity is still low without flares reported during last 24 hours. We expect such a low level of activity to persist in the coming hours. During last 24 hours there were no Earth directed CMEs and the solar protons remained at the background level.

The Earth is still inside the slow solar wind with the speed of about 315 km/s. The interplanetary magnetic field magnitude is presently 4 nT. The geomagnetic conditions are quiet to unsettled and we expect such geomagnetic conditions to persist in the coming hours.

Today's estimated international sunspot number (ISN): 000, based on 30 stations.
