The SIDC is part of the Royal Observatory of Belgium and a partner in the Solar Terrestrial Center of Excellence (STCE).

INFO FROM SIDC - RWC BELGIUM 2018 Oct 21 12:30UTC

There are no active regions visible on the solar disk. No C-class flares in
past 24 h. Solar activity is expected to remain at low levels.
 
No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar
protons have remained at background levels over the past 24 hours.

The solar wind speed is at 330 km/s with interplanetary magnetic fields of
8 nT. Geomagnetic conditions have been quiet. A sector boundary crossing
occurred around 07:00 UT, the interplanetary magnetic field polarity
changed from negative to positive. The solar wind speed started increasing
since then, marking the late arrival of the high speed solar wind stream
associated with the low latitudinal extension of the northern polar coronal
hole coming to Earth. The effect is expected to be weak, producing up to
active periods. A patchy negative polarity coronal hole traversed central
meridian yesterday, its associated high speed stream will affect the Earth
around October 24.
