Bulletin

The last reported flare (B-class) was more than 96 hours ago. This very low level of solar activity is expected 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.

Earth is still inside the slow solar wind with the speed of about 330 km/s and the interplanetary magnetic field magnitude of 3 nT. The arrival of the fast solar wind associated with the patchy equatorial, negative polarity coronal hole is expected midday tomorrow, it might induce unsettled to active geomagnetic conditions. The geomagnetic conditions are presently quiet and we expect them to remain so in the coming hours.

Today's estimated international sunspot number (ISN): 000, based on 18 stations.
