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 Oct 30 12:47:13

Seven M-class flares and six C-class flares were counted since the last
bulletin. An M3.5 flare was the largest flare, peaking at 1:35 UT,
originating from Catania sunspot group 88 (NOAA AR 2192). Catania group 88
is currently located at the west limb and although it is difficult to
determine it's characteristics, the region seems to have shrinked. All
other regions on the front side of the solar disk were relatively stable.
Catania group 88 is still capable to produce large flares, mainly at the
M-level, with a minor chance for another X-flare. 
We retain the warning condition for a proton event.
No Earth-directed CMEs were observed in coronagraphic imagery.The solar
wind speed observed by ACE is low at around 350 km/s. The interplanetary
magnetic field has a magnitude of about 5 nT. A sector boundary crossing is
observed at about 08:00 UT on October 30 as the phi angle changed from a
mostly positive to negative orientation. 
Mostly quiet geomagnetic conditions are expected, with a chance for an
isolated time slot of active conditions (K=4).
