Bulletin

Only minor C-class flaring activity in past 24 hours. NOAA AR 2169 produced again the strongest one (C3.4, peak 17:30 UT on September 18). All regions visible on the solar disk have a simple magnetic structure (alpha or beta configuration), so flaring levels are not expected to grow significantly. Nevertheless, a group of seemingly more complex active regions is rotating into view now. A disturbance arrived to ACE at 07:00 UT with interplanetary magnetic field magnitudes reaching 18 nT and causing active and minor storm conditions at planetary levels (Kp 4 and 5). The cause could be a glancing blow of a CME related to an M1.5 flare on September 14. The magnetic field is currently very fluctuating but slowly returning to nominal levels, more active periods may occur in the next 24 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 062, gebaseerd op 15 stations.
