Bulletin

Solar X-ray flux remained below B level throughout the period. There are no active regions on disk 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 was close to nominal with Solar wind speed recovering from around 400 km/s at the start of the period to a minimum of 330 km/s, while presently around 360 km/s. Total magnetic field was in the 2-8.5 nT range with Bz variable. The magnetic field phi angle was in the negative sector. Solar wind may become somewhat enhanced again tomorrow under the possible influence of the coronal hole that passed central meridian midnight January 12/13.

Geomagnetic conditions were quiet to unsettled (local K Dourbes and NOAA Kp 1-3). Quiet to unsettled conditions are expected over the next days with a possibility for an isolated active period.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 14 Stationen.
