Bulletin

Solar activity was very low with X-ray flux remaining below B level. There are currently no spotted regions on the visible disk, and chances for any flare occurrences are very low.

SDO/AIA 304 images show the eruption of prominence material at around N30W30 from around 5:00UT onwards. Currently available coronagraph imagery does not yet (last SoHO/LASCO C2 image at 8:00UT) show the signs of any possibly associated CME. No other CMEs were observed in coronagraph data.

Proton flux levels are at background values and are expected to remain so.

Solar wind remained just slightly enhanced with Solar wind speed increasing to just under 400 km/s. The total magnetic field was between 3 and 7.5 nT with a variable Bz. The magnetic filed phi angle was initially fluctuating but seems to have settled more steadily in a positive sector now. Solar wind conditions are expected to first recover to nominal but the influence of the coronal holes that crossed the equator over the weekend (a faint patchy region of negative polarity just south of the equator and more notably a low latitude extension of the positive polarity northern polar coronal hole) may cause some further minor perturbations in two to three days from now.

Geomagnetic conditions were quiet (both NOAA Kp and local K Dourbes 1-2) and are expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 15 Stationen.
