INFO FROM SIDC - RWC BELGIUM 2019 Jan 20 12:30UTC

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.

Solar wind conditions are nominal. Solar wind speed decreased further from
around 390 km/s to around 340-350 km/s. Total magnetic field was below 4nT.
The magnetic field phi angle was predominantly 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 expected to set in January 23/24.

Geomagnetic conditions were mostly quiet (local K Dourbes 0-2) with an
isolated unsettled period observed in NOAA Kp (0-3).
Quiet geomagnetic conditions are expected over the next days, but will
later increase to unsettled (from January 22) and thereafter (January
23/24) active periods.
