The flaring activity during last 24 hours was on the low C-class level. Thestrongest flare reported was the C 3.0 flare (peaking at 17:07 UT onOctober 06), originating from the Catania sunspot group 69 (NOAA AR 2185)at that moment situated close to the east solar limb. The flare wasaccompanied with the coronal dimming and the CME first seen in the SOHOLASCO C2 field of view at 17:12 UT. The CME had angular width of about 110degrees and the projected speed of about 350 km/s (as reported by CACTUSsoftware package). This CME will not arrive at the Earth. We expect flaringof the C-class level in the coming hours.The Earth is currently inside aslow solar wind with the speed of 350 km/s. The interplanetary magneticfield is stable with the magnitude of about 4 nT. The geomagneticconditions are quiet and expect to remain so during the following hours.
INFO FROM SIDC - RWC BELGIUM 2014 Sep 30 12:20:03 There are currently 10 sunspot groups on the solar disk, with two active regions approaching the east limb. However, only NOAA 2173 is producing low-level C-class flaring, the strongest being a C3.3 flare peaking at 21:32UT. NOAA 2175 and NOAA 2177 have some mixed magnetic polarities, but have remained quiet. No Earth-directed CMEs have been observed. The x-ray background flux is already 5 consecutive days above the C1-level. Two 20-degrees long filaments visible in the western solar hemisphere have remained quiet. C-class flaring is expected, with a reasonable chance on an isolated M-class flare. Solar wind speed varied mostly between 340 and 380 km/s, with Bz fluctuating between -7 and +5 nT. Quiet to unsettled geomagnetic conditions were observed, with Kp having some active periods. Geomagnetic conditions are expected to be quiet to unsettled, with locally an active period possible.
