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 Sep 21 13:08:20

The strongest flare reported in last 24 hours is still ongoing C5.2 flare
(peaked at 11:53 UT). The flare seem to originate from the NOAA AR 2166.
Two eruptions of filaments situated at the center of the solar disc, on
September 20 (at about 06:00 UT) and on September 21 (at about 02:10 UT),
did not seem to be associated with wide CMEs. Majority of the recent
flaring activity originated from NOAA AR 2171 and NOAA AR 2172 currently
situated close to the east solar limb. We expect C-class flares and
possibly also an isolated M-class flare in the coming hours, in particular
from these two active regions.The solar wind speed remains to have value of
about 520 km/s. The interplanetary magnetic field magnitude is stable with
the value of 4 nT. The geomagnetic conditions are quiet and expected to
remain so in the following 48 hours.
