Bülletään

Six active regions were identified on the solar disk today. Once more NOAA active regions (AR) 2422 and 2423 were the main players, producing nine M-class flares and several C-class flares. The largest one was a M7.6 flare, peaking at 14:58 UT. The flares were either impulsive or the accompanying CME was too weak and without an Earth-directed component to be of any influence for the Earth. NOAA 2422 has stretched in the E-W direction but has stopped growing in sunspot area. The region still is a beta-gamma-delta region. The evolution of NOAA 2423 is difficult to follow, but it still produced some flares. Additional M-class flares are expected, with 30% probability for an X-class flares. Due to the position of NOAA AR 2423, we retain the warning level for a potential proton event.

The Earth is still inside a slow (values between 340 and 380 km/s) solar wind flow and the interplanetary magnetic field magnitude remains around 5 nT. The geomagnetic conditions are quiet (K<3) to unsettled (K=3) and are expected to remain so.
