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 18 13:28:27

NOAA AR 2169 produced an M1.2 flare with peak at 08:41 UT, with an
associated Type II radio burst produced by a shock with estimated velocity
of 537 km/s. No CME is visible yet in coronagraph images, but more data is
needed yet to rule out a possible CME (due to the location of the source
region, a CME would most probably not be geoeffective). A partial halo CME
was seen yesterday at 17:37 UT off the northeastern limb of the Sun, this
is a backsided event that will not affect the Earth.Geomagnetic conditions
are quiet and expected to remain so.
