Bulletin

Solar X-ray flux remained below B level throughout the period. The Solar disk is again spotless and X-ray flux is expected to continue to be below C level.

No earth directed CMEs have been recorded.

The proton flux levels were at background values and are expected to remain so.

Solar wind conditions were slightly elevated with solar wind speed reaching a maximum of 526 km/s but now back at around 450 km/s. Total magnetic field saw a maximum of close to 11nT before starting a gentle decaying trend to a now nominal value below 5nT. Bz was mostly variable with a southward peak of -8nT. The slightly elevated Solar wind conditions are expected to return to an ambient regime.

Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-3, NOAA Kp 1-2) and are expected to be quiet over the next days.

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