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 31 12:49:39

During the past 24 hours, solar flaring activity was at the C-level, with a
C9.7 as strongest flare. The background irradiation is decreasing as
Catania group 88 (NOAA 2192) is rounding the west limb. Flares originated
from Catania groups 88, 98 and 3 (NOAA 2192, 2200 and 2201 respectively).
The C6.9 flare, originating from Catania group 3, peaked at 13:12 UT on
October 30 and C2.3 flare, originating from Catania group 98, peaked at
15:03 UT. Both flares were accompanied by radio type II bursts and narrow
eastward propagating CMEs. These CMEs will not have any impact on Earth.
Due to the position of Catania group 88, we retain the warning condition
for a proton event. 

The solar wind speed, observed by ACE, increased from 350  to 450 km/s, the
interplanetary magnetic field went up in magnitude to about 12 nT and also
the temperature increased. A northern coronal hole (extending from N10 to
N55) has passed the central meridian and the associated high speed stream
might arrive at the end of November 2. Quiet to active conditions are
expected, with limited chances for minor storm conditions.
