[rwc]

Very low flare activity is expected on 21-Jan. The solar wind speed is
above nominal values, currently around 500 km/s, but is declining due
to the waning effects of a coronal hole. Geomagnetic conditions are
currently at quiet to unsettled levels. High-frequency radio
communications may experience minor depressions in maximum useable
frequencies and periods with poor propagation conditions.
