Bulletin

There are presently no active regions observed on the visible side of the solar disc, and accordingly solar flaring activity is very low, without any C-class or even B-class flares reported during last 24 hours. We expect such a low level of the activity to persist in the coming hours. There were no wide and/or Earth directed CMEs reported and the solar protons remained at the background level.

The solar wind speed additionally decreased and it now amounts about 330 km/s. The interplanetary magnetic field magnitude fluctuates around 3 nT. The geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours.

Today's estimated international sunspot number (ISN): 000, based on 21 stations.
