The Sun Online and solar activity. November 12, 2013

The strongest flare in the past 24 hours was an M2.4 flare (peaked at 11:18 UT today) originating from the  NOAA AR 1895, which just appeared from behind the east solar limb. From the current data it is not possible to say if the flare was associated with the CME. Two most complex sunspot groups, at the moment, are NOAA AR 1895 situated close to the East solar limb which produced M-class flare this morning and Catania sunspot group 35 (NOAA AR 1890) which retains the beta-gamma-delta configuration of its photospheric magnetic field. Both active regions have the potential for producing M-class flares and possibly also X-class flare. Since the Catania sunspot group 35 (NOAA AR 1890) is situated in the western solar hemisphere we maintain the warning condition for a proton event.The solar wind speed is around 500 km/s and the interplanetary magnetic field (IMF) magnitude is about 5 nT. We expect quiet to unsettled (K < 4) geomagnetic conditions in the coming hours. The arrival of the halo CME which erupted on November 10 is expected on November 13 resulting in active to minor storm geomagnetic conditions.
