INFO FROM SIDC – RWC BELGIUM 2014 Oct
Four low-level C-class flares were recorded. The strongest was a C1.9
peaking at 22:15UT and produced by NOAA 2172 from behind the west limb. The
x-ray background flux has decreased below the C1-level. There are currently
8 sunspot groups visible on the solar disk. Most of them are fairly simple,
and contain a filament or are close to one. Further C-class flaring is
expected. A 20-degrees long, thin, but dynamical s-shaped filament has
rounded the southeast limb. This area seems to have been responsible for a
filament eruption on 03 October between 03:00 and 04:30UT. The associated
CME was not directed to Earth.
Solar wind speed increased from about 330 to 370 km/s. Bz was initially
fluctuating around 0 nT untill about 05:00UT, when it gradually increased
to the current +10 nT. Geomagnetic conditions were quiet to unsettled, and
are expected to remain so, with locally an active episode possible.
