公告

No flares were reported during the past 24 hours, although the X-ray background flux remains around the C1 level. The NOAA AR 2209 maintains the beta-gamma-delta configuration of its photospheric magnetic field, so we expect flaring activity on the C-level, with an isolated M-class flare possible but unlikely. A filament situated around N20W40 seems to undergo an eruption, although due to its small size we do not expect a large CME to occur (more information will be provided as the coronagraph data becomes available). The Earth is currently inside a slow (around 420 km/s) solar wind flow with the magnitude of the interplanetary magnetic field (IMF) up to 6 nT. Due to this very slight elevation of the IMF magnitude, an interval of K = 4 was reported by Dourbes, IZMIRAN, and NOAA. We expect quiet to unsettled (K < 4) geomagnetic conditions, possibly with isolated intervals of active (K = 4) conditions.
