Bulletin

NOAA AR 2790 (alpha) is rotating out of view over the west limb, NOAA AR 2792 (beta) rotated into view from the east one. They did not produce any C-class flares or larger in the past 24 hours. But they produced several B-class flares. C-class flares are possible in the next 24 h.

No Earth directed CMEs were seen in the last 24 hours.

The greater than 10 MeV proton flux is at background levels and is expected to remain at background levels. The greater than 2MeV electron flux did not exceed the 1000 pfu alert threshold, it is expected to remain so in the next 24 hours. The 24h electron fluence was at moderate levels, it is expected to remain so in the next 24 hours

The solar wind speed ranged from 425 km/s to 375 km/s with interplanetary magnetic field magnitude around 5 nT, in the past 24 hours. The magnetic field polarity is negative, pointing towards the Sun. Bz was never below -5 nT.

Geomagnetic conditions were quiet to unsettled (K Dourbes 0-3 and Kp 0-3). Geomagnetic conditions are expected to remain quiet.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 011, basierend auf 12 Stationen.
