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 24 12:16:19

Five low-level C-class flares were observed over the last 24 hours. The
largest was a C4.1 peaking at 11:04UT in NOAA 2217, which was also the
source of 3 other C2 flares. One of these peaked on 23 November at 16:14UT
and was associated to a non-Earth directed CME, first visible in LASCO at
16:24UT. NOAA 2216 produced the remaining C2 flare. The other regions were
quiet, with NOAA 2209 still maintaining a weak delta spot in its trailing

More C-class flares are expected, with a chance on an isolated M-class

The IMF is directed away from the Sun, with Bz varying between -7 and +4
nT. Solar wind speed varied between 470 and 360 km/s and is currently near
400 km/s. The geomagnetic field was quiet to unsettled (K<3), and is
expected to remain so, with an isolated active period possible.
