Bulletin

The level of the solar flaring activity is extremely low, with no reports of C-class and even B-class flares. The last reported flare (B-class or stronger) was B1.0 flare on September 11. We expect such a low lever of activity to persist in the coming hours. During last 24 hours we did not observe signatures of the possibly 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 330 km/s, and the interplanetary magnetic field magnitude is 3 nT. The geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours. We can expect unsettled geomagnetic conditions late on September 22 due to expected arrival of the fast solar wind.
