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.
