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 Thu Mar 11 2010, 1157 UT Two active regions are visible on the disc, NOAA AR 11054 (Catania 52) emerged on the east limb with a beta magnetic configuration and Catania 51 located close to disc center (no NOAA number yet). They are not expected to produce relevant flaring activity anytime soon. A CME was seen over the north east limb, it\'s not expected to be geoeffective. Geomagnetic conditions ranged from quiet to unsettled due to the slightly fast solar wind (~470km/s) coming from a weak coronal hole, its effect is expected to fade in the next 24 hours.
