Bulletin

Solar X-ray flux remained below B level throughout the period. Some small spotted region seems to be emerging near N16W22 but 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 was slightly enhanced reaching a maximum of 432 km/s during the period but is now back around 360 km/s. Total magnetic field was mostly in the 3-9 nT range but mostly around a nominal 5nT with Bz variable. The magnetic field phi angle was in the negative sector. Solar wind is expected to be close to nominal with some minor enhancements possible.

Geomagnetic conditions were quiet (local K Dourbes 0-2 and NOAA Kp 1-2). Quiet conditions are expected over the next days with initially some unsettled periods possible.

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