Bulletin

There are two active regions on the visible solar disc. NOAA AR 2735 is decaying and has now alpha magnetic field configuration. NOAA AR 2736 has evolved into beta-gamma-delta and has produced seven C-class flares in the past 24 h, the largest wass a C4.8 one peaking at 05:14 UT. More C-class flares are expected and M-class flares remain possible.

No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 h.

The solar wind speed is at 320 km/s with interplanetary magnetic fields of 4 nT. Quiet conditions were observed in the past hours and the situation is not expected to change until the CME from March 20 arrives to the Earth (expected on March 23 around noon), K up to 5 can be expected (with possible periods of K = 6).

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 031, basierend auf 19 Stationen.
