Bulletin

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.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 127, gebaseerd op 22 stations.
