Bulletin

Solar activity was very low. There are currently no sunspot regions on the visible solar hemisphere. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Quiet flaring conditions are expected to continue.

Earth remained under the waning influence of the high speed stream (HSS) from the negative polarity coronal hole (CH). Solar wind speed varied between 570 and 510 km/s, ending the period near 550 km/s. Bz fluctuated between -5 nT and +4 nT. The interplanetary magnetic field was directed towards the Sun.

The geomagnetic field was at quiet to active levels. Mostly quiet to unsettled conditions are expected, with still a chance on an active episode.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 11 Stationen.
