Welcome to the Solar Influences Data Analysis Center (SIDC), which is the solar physics research department of the Royal Observatory of Belgium. The SIDC includes the World Data Center for the sunspot index and the ISES Regional Warning Center Brussels for space weather forecasting.

INFO FROM SIDC - RWC BELGIUM 2018 Jan 19 12:35UTC

Over the past 24 hours solar activity has been quiet. No significant flares
have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have
been detected. Solar activity is expected to remain low over the next 24
hours with a small chance of C-class flares.
The solar wind speed has increased from around 325 to around 375 km/s over
the past 24 hours. The total magnetic field strength has increased from
around 5 to 9 nT. The Bz component has ranged between -6 and +6 nT.
Geomagnetic conditions ranged between Kp index 0-3 (NOAA) and local K index
0-2 (Dourbes) over the past 24 hours. Geomagnetic conditions may increase
as a coronal hole has passed into the Western hemisphere and may increase
geomagnetic activity later today.
