Another X-class flare was produced by Catania sunspot group 88 (NOAA AR 2192); an X2.1 flare peaked at 14:47 UT on October 27. Also three M-class and several C-class flares were added to the activity list of this region. No associated CME was observed, nor was there an increase in proton flux. The region retains its area and magnetic complexity and has still high potential to produce additional flares up to the X-level. It is currently located close to the West limb and a strong eruption may result in a rise of the proton flux. The extended filament in the northern hemisphere has the potential to lift off and produce an Earth- directed CME. Earth is inside a slow solar wind, with a speed near 400 km/s. The interplanetary magnetic field magnitude reaches values up to 8 nT, with an often southward oriented Bz. Mostly quiet geomagnetic conditions are observed, with a few isolated time slots of active (K=4, measured at Dourbes) conditions. Quiet to active conditions are expected to continue.
Today's estimated international sunspot number (ISN): 071, based on 13 stations.
