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 2014 Sep 20 13:40:07

Solar activity is low. The strongest flare, among three C-class flares
reported during last 24 hours was a C3.3 flare (peak time at 18:32  UT) on
September 19. The flare originated from the NOAA AR 2171 currently situated
at the east solar limb. Solar activity is expected to remain low with
occasional C-class flares.The solar wind speed is about 500 km/s. In the
wake of the passage of the interaction region between the fast and slow
solar wind flow the interplanetary magnetic field magnitude has decreased
to low values and it currently amounts about 5nT. The geomagnetic
conditions are quiet and expected to remain so in the following 48 hours.
