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 2017 Mar 24 12:30UTC

In the past 24 hours, no C flares were observed. Very low solar activity
(no C flares) is expected in the next 24 hours.
Over the past 24 hours, solar wind speed measured by DSCOVR varied between
about 530 and 750 km/s, while the magnitude of the Interplanetary Magnetic
Field (IMF) ranged between about 1 and 11 nT. Bz was never below -5 nT.
Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1
and 3) were registered in the past 24 hours. Quiet to unsettled levels (K
Dourbes < 4) are expected on March 24, with a chance for active (K Dourbes
= 4) intervals. Quiet to unsettled geomagnetic conditions (K Dourbes < 4)
are expected on March 25 and 26.
