公告

The solar flaring activity continues to decrease. The strongest flare of the past 24 hours was the C8.6 flare peaking yesterday at 18:33 UT in the Catania sunspot group 28 (NOAA AR 1967). All other flares did not reach the C3 level. Catania sunspot groups 27 and 28 (NOAA ARs 1968 and 1967 respectively) are currently situated at the west solar limb, maintaining respectively beta-gamma and beta-gamma-delta configurations of the photospheric magnetic field. Due to position of these groups at the west limb, a major CME in one of them may lead to a proton event, so we maintain the warning condition. We expect flaring activity to continue on the C-level, with an isolated M-class flare being unlikely. The Earth is now exiting the trailing part of the ICME that followed the shock arrival on February 7. The ICME triggered active (K = 4) to minor storm (K = 5) conditions according to IZMIRAN and NOAA respectively. The solar wind speed is currently around 420 km/s, and the interplanetary magnetic field magnitude is around 8 nT. We expect quiet geomagnetic conditions, with isolated intervals of active conditions (K = 4) being possible but unlikely.
