NOAA AR 2497 has increased its magnetic complexity and now has
beta-gamma-delta configuration of its photospheric magnetic field. It
produced 3 C-class flares and an M-class flare in the past 24 hours (two
more C-class flares were produced by the NOAA AR 2492). We expect the
flaring activity on the M-level from the NOAA AR 2497. The M1.0 flare
peaking at 10:47 today was not accompanied by a CME. The C8.9 flare peaking
at 21:03 UT on February 11 in the NOAA AR 2497 was accompanied by coronal
dimmings, an EIT wave, and a post-eruption arcade observed by SDO/AIA. The
associated halo CME (angular width around 270 degrees) first appeared in
the SOHO/LASCO C2 field of view at 21:28 UT. Due to the position of the CME
source region close to the solar disk center, the CME will most probably
arrive at the Earth. The arrival may be expected late on February 14 -
early on February 15. A minor to moderate geomagnetic storm (K around 5 to
6) may be expected. 
The Earth is currently inside an ICME, probably associated with a delayed
arrival of the CME observed on the Sun late on February 5 (the solar wind
speed is currently rather low, around 350 km/s). The interplanetary
magnetic field (IMF) magnitude is currently around 14 nT. The IMF
north-south component Bz had extended southward intervals, but due to low
solar wind speed only active geomagnetic conditions (K = 4) were reported
by Dourbes, IZMIRAN, and NOAA. We expect unsettled to active geomagnetic
conditions in the coming hours.
