Bulletin

Solar activity was at very low levels. There is no sunspots on the visible side of solar disk. No coronal mass ejections (CMEs) were observed. Integral proton flux for protons with energies above 10 MeV remained at background level. Quiet flaring conditions are expected. The earth environment is under the influence of a polar coronal hole. Solar wind speed fluctuated between 480 and 570 km/s. Total interplanetary magnetic filed fluctuated between 5 and 9 nT, while its Bz component fluctuated between -9 and 9 nT, being rather negative. The geomagnetic field was at active and minor storm levels most of the time, with unsettled levels reached locally in Dourbes at the end of the period. Active geomagnetic conditions are expected, with some intervals of minor storming.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 17 Stationen.
