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 Jul 17 12:30UTC

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

The solar wind speed gradually increased over the period from 370 to a
maximum of around 500 km/s at 07:15 UT (ACE). The Bz varied between -5 and
+4 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 (NOAA) ranging between 0-2 and the local K
index (Dourbes) ranging between 1-3 over the past 24 hours.

Quiet geomagnetic conditions are expected with possible isolated unsettled
intervals.
