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 27 12:54:59

NOAA 2222 developed close to the southeast limb and is actively flaring. It
was responsible for at least 10 C-class flares, including a C8.2 flare
peaking at 00:47UT which was the strongest event of the observing period.
Departing region NOAA 2209 was the only other region to produce a C-class
flare. The other regions were quiet, with NOAA 2219 having some mixed
polarities. The x-ray background flux increased from about B9 to nearly C2.
A filament eruption was observed in the NW quadrant around 16:00UT on 26
November. A slow CME first observed in LASCO/C2 at 17:36 may have been
associated to it. The other filaments were quiet. None of the observed CMEs
are directed to Earth.  

Low-level M-class flares are possible.

A sector boundary crossing (SBC) occurred around 03:00UT. IMF turned
towards the Sun. Solar wind speed gradually increased from about 300 to 400
km/s. Bz varied between -7 and +9 nT, but was mostly positive after the
SBC. The geomagnetic field was quiet. Geomagnetic conditions are expected
to be quiet to unsettled, with an isolated active period not excluded.
