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 2019 Jun 18 12:30UTC

Solar activity was at very low levels. The Sun remains spotless and no
significant flares have been recorded.  No Earth directed coronal mass
ejections (CMEs) were observed over the last 24 hours in the available
coronagraph imagery. The greater than 10 MeV proton flux was at nominal
values. Solar activity is expected to remain at very low levels. 

The solar wind fluctuated between 300 and 345 km/s (DSCOVR). Bz varied
between -4 and +5 nT. The interplanetary magnetic field was predominantly
directed away from the Sun (positive sector). Quiet to unsettled
geomagnetic conditions were observed, with the Kp index ranging between 0-1
(NOAA) and the local K index (Dourbes) ranging between 0-3 over the past 24
hours.

Quiet to unsettled geomagnetic conditions are expected due to the arrival
of the solar wind streams associated with a series of fragmented negative
polarity coronal holes. Isolated active periods are also possible.
