Only two sunspot groups were reported by NOAA today. The NOAA AR 2497 maintains beta-gamma-delta configuration of its photospheric magnetic field. It produced most of the C-class flares of the past 24 hours and the M1.8 flare peaking at 15:24 UT yesterday. We expect flaring activity on the C-level, with an isolated M-class flare from the NOAA AR 2497. A low- latitude extension of the southern polar coronal hole reached the solar central meridian yesterday. The associated fast solar wind steam is expected to arrive at the Earth on February 16. The Earth is currently inside a slow (around 380 km/s) solar wind flow with slightly elevated magnitude of the interplanetary magnetic field (6-7 nT). The geomagnetic conditions are quiet and are expected to remain so in the coming hours. Late today or early tomorrow we expect the arrival of the ICME associated with the halo CME observed on the Sun on February 11. A minor to moderate geomagnetic storm (K around 5 to 6) may be expected.
Today's estimated international sunspot number (ISN): 054, based on 08 stations.
