Bülletään

The strongest flare observed on the Sun during the past 24 hours was the X3.1 flare peaking at 21:41 UT yesterday in the Catania sunspot group 88 (NOAA AR 2192). SOHO/LASCO data demonstrate that the flare was accompanied only with a very weak and narrow CME. No geomagnetic consequences are expected. Despite the decrease in the area of the Catania sunspot group 88, it maintains the beta-gamma-delta configuration of its photospheric magnetic field, so we expect the flaring activity up to X-level from this sunspot group. As the Catania sunspot group 88 is currently situated close to the solar central meridian, a major eruption in this active region may lead to a geoeffective CME and a proton event. A long filament in the northern hemisphere is now crossing the solar central meridian. Its possible eruption may lead to an Earth-directed CME. The Earth is currently inside a slow (around 390 km/s) solar wind flow with average (around 5 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.
