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 Oct 01 12:31:31

Only one C-class flare was observed during the period. This C6.7 flare was
located in NOAA 2172 and peaked at 03:06UT. The other 8 sunspot groups have
been quiet. NOAA 2178 seems to be the most complex, with opposite magnetic
polarities close to each other but no apparent delta structure. A CME first
observed by LASCO at 08:48UT on 01 October was associated to a prominence
eruption near the east limb. It is not Earth directed. The x-ray background
flux is still above the C1-level. Two 20-degrees long filaments visible in
the western solar hemisphere have remained quiet.   

C-class flaring is expected, with still a chance on an isolated M-class

Solar wind speed varied between 350 and 400 km/s, with peaks near 450 km/s.
Bz fluctuated between -7 and +5 nT. A few isolated active periods were
recorded. Geomagnetic conditions are expected to be quiet to unsettled,
with isolated active periods possible.
