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.

PRESTO FROM SIDC - RWC BELGIUM Tue Mar 16 2010, 1253 UT Solar activity is expected to remain low, with only occasional C flares. The solar wind speed remains slow, but the arrival of an Earth-directed CME is expected late today March 16 or tomorrow March 17. This rather weak disturbance may trigger temporary active geomagnetic conditions with a chance for minor geomagnetic storm levels, mainly on March 17. Thereafter, the geomagnetic field will return to quiet to unsettled conditions.
