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 26 12:25:23

Four C-class flare were observed, with NOAA 2217 producing the strongest
event of the period (C2.9 peaking at 06:17UT). Slowly developing region
NOAA 2219 and a new, currently unnumbered, region near the east limb merit
some attention, as they were the sources of the other C-class flares.
Numerous, but quiet, filaments are present on the solar disk, with the
longest measuring 40 degrees and located in the NE quadrant. No
Earth-directed CMEs were observed.

Further C-class flaring is expected, with a small chance on an isolated
M-class flare.

Solar wind speed declined from about 400 to 320 km/s. Bz was mostly
negative and varied between -6 and +4 nT. The IMF is directed away from the
Sun. The geomagnetic field was quiet to unsettled (K<4), and is expected to
remain so. Effects from an expected Sector Boundary Crossing and the
possible high speed stream from the extension of a coronal hole may result
in an isolated active period on 27-28 November.
