Bulletin

Solar activity remains to be extremely low with no C-class or even B-class flares reported. We expect this level of the flaring activity to persist in the coming hours. During last 24 hours there were no Earth directed CMEs reported, and the solar protons remained at background level.

The Earth is presently inside the slow solar wind with the speed of 340 km/s. The interplanetary magnetic field magnitude is low and it amounts 3 nT. The geomagnetic conditions are quiet and we expect them to remain so in the coming hours. Starting from the late evening today and during the day tomorrow, we might expect unsettled to possibly active geomagnetic conditions due to the expected arrival of the fast solar wind associated with the coronal hole which reached central meridian in the morning of January 09.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 09 Stationen.
