Bulletin

Solar activity was low with X-ray flux remaining initially below C level, while a C flare was eventually produced just before the end of the period by a newly emerging region near N12W30 (numbered NOAA 2558). It peaked at 11:58UT at magnitude C1.7. New region NOAA 2557 also got numbered but seems to be short lived. Most regions on disk are fairly simple and mostly inactive and X-ray flux is expected to remain mostly below C-level, while C-flaring remains possible from the newly emerging region 2558. No Earth directed CME's have been recorded in coronagraph data. Solar wind speed remained elevated with a maximum of around 650 km/s and later a decrease to values of around 550 km/s. Total magnetic field further decreased to a nominal 4nT with Bz variable. The magnetic field phi angle indicated a positive polarity sector. Solar wind conditions should further recover to nominal levels. Geomagnetic conditions were quiet to unsettled (both local K Dourbes and NOAA Kp 1-3) and are expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 055, basierend auf 16 Stationen.
