Bülletään

Solar X-ray flux remained below B level throughout the period. The Solar disk is 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.

An equatorial positive polarity coronal hole is now starting to transit the central meridian.

Solar wind conditions have returned to nominal. Solar wind speed decreased steadily from around 480 km/s to around 400 km/s. Total magnetic field was below 5nT. The magnetic field phi angle was in the negative sector. Nominal Solar wind conditions are expected over the next days. The Solar wind sector change preceding the coronal hole that is now transiting the central meridian is not expected before January 22 and further associated Solar wind enhancements are only expected to set in January 23/24.

Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp 0-2) and are expected to remain quiet over the next days.
