Bulletin

NOAA 2385 (Catania 11) produced the only flare of the period: a C1 flare peaking at 18:36UT. The other sunspot regions were quiet. Old active region NOAA 2371 is making its reappearance from behind the east limb. No obvious Earth-directed coronal mass ejections (CME) were observed.

There remains a chance on an isolated C-class flare.

Solar wind speed is gradually declining and currently varying between 570-600 km/s. Bz oscillated between -8 and +7 nT. The interplanetary magnetic field was mostly directed away from the Sun. Quiet to active geomagnetic conditions were observed.

Quiet geomagnetic conditions are expected with a chance on an active episode, as the influence of the high speed stream of the coronal hole is gradually subsiding.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 081, basierend auf 11 Stationen.
