Bulletin

Four C-class flares were reported in the past 24 hours, all in the NOAA AR 2497. The strongest flare was the C6.8 flare peaking at 17:21 UT yesterday. NOAA AR 2497 maintains beta-gamma-delta configuration of its photospheric magnetic field, so we expect flaring activity on the M-level. The Earth is currently inside the trailing part of the ICME, with the solar wind speed around 380 km/s and the interplanetary magnetic field magnitude around 10 nT. We expect quiet to unsettled geomagnetic conditions (K < 4) in the coming hours, possibly with isolated intervals of active geomagnetic conditions (K = 4). Late on February 14 - early on February 15 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.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 034, gebaseerd op 13 stations.
