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 Aug 20 09:43:35

There are 6 active regions on the visible side of the solar disk. Only NOAA
AR 12146 (in NE quadrant) has shown a significant growth in the past 24
hours. We expect it will push up solar activity to C-class flaring levels,
though further growth in size, complexity and thus flaring levels cannot be
excluded. Note also that flaring activity is observed from behind the NE
solar limb.Quiet geomagnetic conditions are expected in the coming 3 days:
there are no high speed wind streams expected from coronal holes, nor are
there any new CMEs on the way to the Earth. The arrival yesterday (Aug 19)
of the Aug 15 CME resulted in a Kp=6 episode. The Bz component of the IMF
has now turned fully Northward, thereby ending the geomagnetic storm.
