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 30 12:38:33

The Sun produced several small C-class flares, originating from NOAA AR
2146, AR 2149 and AR 2152. AR 2146 has now rotated around the West limb. No
Earth-directed CMEs were detected. More C-class flares are expected, with a
slight chance for M-class flares. Solar wind speed values ranges between
400 and 450 km/s. The magnitude of the interplanetary magnetic field
remained relatively stable around 6 to 7 nT, while Bz is fluctuating
between -6 and +6 nT. Geomagnetic conditions are unsettled to active and
are expected remain so for the next 48 hours, due to the influence of the
increased solar wind related to the equatorial coronal hole.
