Bulletin

The strongest event of the period was a C7.5 flare peaking at 07:10UT. It was produced by new sunspot region NOAA 2615 (S08E60), which is slowly developing. This region is still small but shows some magnetic mixing. NOAA 2612 and developing region NOAA 2614 were quiet. NOAA 2611 was very dynamic and managed to produce a B9 flare at 01:55UT from behind the west limb. No earth-directed coronal mass ejections (CMEs) were observed. The greater than 10MeV proton flux was at nominal levels.

C-class flares are possible, with a slight chance on an isolated M-class flare pending further evolution of NOAA 2615.

Solar wind speed leveled at values near 450 km/s. Bz fluctuated between -5 nT and +4 nT. The interplanetary magnetic field was mostly directed away from the Sun. Solar wind parameters are expected to evolve further to nominal values.

The geomagnetic field was at quiet to unsettled levels, and is expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 049, basierend auf 18 Stationen.
