Bülletään

There are currently 10 sunspot groups on the solar disk, with two active regions approaching the east limb. However, only NOAA 2173 is producing low-level C-class flaring, the strongest being a C3.3 flare peaking at 21:32UT. NOAA 2175 and NOAA 2177 have some mixed magnetic polarities, but have remained quiet. No Earth-directed CMEs have been observed. The x-ray background flux is already 5 consecutive days above the C1-level. Two 20-degrees long filaments visible in the western solar hemisphere have remained quiet. C-class flaring is expected, with a reasonable chance on an isolated M-class flare. Solar wind speed varied mostly between 340 and 380 km/s, with Bz fluctuating between -7 and +5 nT. Quiet to unsettled geomagnetic conditions were observed, with Kp having some active periods. Geomagnetic conditions are expected to be quiet to unsettled, with locally an active period possible.
