Bulletin

There are presently no active regions on the visible side of the Sun, and accordingly solar activity is low (without reported flares). We expect very low level of solar activity to persist in the coming hours. Coronagraph observations do not show any Earth directed CMEs observed in the past 24 hours.

During last 24 hours the solar wind speed was fluctuating between 420 and 350 km/s, and its present value is about 370 km/s. The interplanetary magnetic field magnitude has the value of about 8nT. The geomagnetic conditions were quiet to unsettled and we expect them to stay so in the coming hours.

Due to very low solar and geomagnetic activity we maintain the all quiet alert (issued on April 30).

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 19 Stationen.
