Bulletin

There are currently 8 sunspot regions visible on the solar disk. NOAA 2253 produced the only C-class flare of the period (C1.8 peaking at 19:05UT). NOAA 2253 has gained in sunspot area, and has developed a weak delta structure in its leading portion. No significant or earth-directed CMEs were detected. Further C-class flaring is expected, with a slight chance on an M-class flare from NOAA 2253. The geomagnetic field was quiet to unsettled. Solar wind speed varied between 410 and 450 km/s, while Bz was mostly negative and varied between -4 and +4 nT. Quiet to unsettled conditions are expected. The extension of a southern polar coronal hole extension is transiting the CM. Its high speed stream may influence the geomagnetic field starting on 04 January.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 090, basierend auf 10 Stationen.
