公告

Six C-class flares were detected on the Sun in the past 24 hours: four in the NOAA AR 2209 and two in the NOAA AR 2216. The strongest flare was the C2.5 flare peaking at 19:56 UT yesterday in the NOAA AR 2209. It was not associated with a CME. The NOAA AR 2209 maintains the beta-gamma- delta configuration of its photospheric magnetic field, so we expect flaring activity on the C-level from this region as well as from the NOAA AR 2216, with an isolated M-class flare possible but unlikely. A long filament in the northern hemisphere is approaching the solar central meridian. Its eruption may lead to an Earth-directed CME. The Earth is currently inside a slow (around 380 km/s) solar wind flow with slightly elevated (7-8 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are expected to stay at the quiet to unsettled level (K < 4) with isolated intervals of active conditions (K = 4).
