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 2013 May 21 12:29:27

Solar activity was eruptive the last 24 hours with 7 C flares mostly
originating from AR NOAA 1748 (Catania 75) which has become more complex
again since yesterday.  AR NOAA 1750 (Catania 78) is decaying, but still
has a possibility to produce M flares and due to its position, also a
proton event.  

A CME was detected by LASCO C2 on May 20th around 13:00 UT with an angle of
around 150 degrees and a speed around 340 km/s.  It should reach Earth on
May 24th around 19:00 UT, but should only have minor impact.  It originated
from AR 1748 with a C flare around 10:30 UT. 

Geomagnetic conditions where quiet to moderate and are expected to remain
so for the next 48 hours.
