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 Nov 22 12:04:53

NOAA ARs 2209 and 2216 (Catania numbers 9 and 14 respectively) have
delta-spots in their trailing parts and continue to produce C-class flares.
The strongest flare of the past 24 hours was the C8.1 flare peaking at
01:01 UT today in the NOAA AR 2209 (Catania number 9). We expect flaring
activity on the C-level, possibly with an isolated M-class flare. A long
filament in the northern hemisphere is now situated across the solar
central meridian. Its eruption may lead to an Earth-directed CME.  The
Earth is currently inside a slow (around 370 km/s) solar wind flow with
slightly elevated (7-8 nT) interplanetary magnetic field magnitude. Due to
low solar wind speed, the geomagnetic conditions remained at the quiet to
unsettled level (K < 4), with one interval of active conditions (K = 4)
reported only by IZMIRAN yesterday evening. The geomagnetic conditions are
expected to stay at the quiet to unsettled level (K < 4),
possibly with isolated intervals of active conditions (K = 4).
