Bulletin

Solar activity was at very low levels. The Sun remains spotless and no significant flares have been recorded. No Earth directed coronal mass ejections (CMEs) were observed over the last 24 hours in the available coronagraph imagery. The greater than 10 MeV proton flux was at nominal values. Solar activity is expected to remain at very low levels.

The solar wind fluctuated between 300 and 345 km/s (DSCOVR). Bz varied between -4 and +5 nT. The interplanetary magnetic field was predominantly directed away from the Sun (positive sector). Quiet to unsettled geomagnetic conditions were observed, with the Kp index ranging between 0-1 (NOAA) and the local K index (Dourbes) ranging between 0-3 over the past 24 hours.

Quiet to unsettled geomagnetic conditions are expected due to the arrival of the solar wind streams associated with a series of fragmented negative polarity coronal holes. Isolated active periods are also possible.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 21 Stationen.
