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 Fri Mar 12 2010, 1246 UT Solar activity is low. Catania region 51 was numbered NOAA 11055, together with NOAA 11054 (Catania 52) are the two active regions visible on the disc. They don\'t have potential for big flares at this time, even though AR 11054 is growing in size. There was an east limb CME yesterday at 20:06 UT detected by CACTUS, it is not expected to be geoeffective. Geomagnetic activity is quiet and will most likely remain so as the effect from the fast coronal hole solar wind is diminishing, there was one active period (Kp=4) early today.
