INFO FROM SIDC - RWC BELGIUM 2019 Dec 14 12:30UTC

Solar flaring activity continues to be very low and we expect such a low
level of flaring activity in the coming hours. During last 24 hours there
were no Earth directed CMEs and the solar protons remained at the
background level.
The solar wind speed is presently about 360 km/s and the interplanetary
magnetic field magnitude is 4 nT. Elongated and patchy equatorial coronal
hole of positive polarity has reached central meridian this morning. The
solar wind originating from this coronal hole might arrive to Earth late on
December 17.
The geomagnetic conditions are presently quiet and we expect quiet to
possibly unsettled geomagnetic conditions (due to expected arrival of the
solar wind originating from the equatorial coronal hole of negative
polarity that reached central meridian in the evening of December 10) in
the coming hours.
