INFO FROM SIDC - RWC BELGIUM 2018 Sep 18 12:30UTC

The visible side of the Sun is presently spotless and consequently there
was no flaring activity reported during last 24 hours. We expect such a low
flaring activity to persist in the coming hours. No Earth directed CMEs
were observed, and the solar protons remained at the background level.

The solar wind speed is slowly decreasing and it presently amounts about
480 km/s. The interplanetary magnetic field magnitude is about 4 nT. The
low latitudinal extension of the northern polar coronal hole has reached
the central meridian this morning. The possible arrival of the associated
fast solar wind might be expected at the Earth late on September 21 or in
the morning of September 22.
During last 24 hours the geomagnetic conditions were quiet to unsettled and
we expect them to stay so in the coming hours.
