Bulletin

Solar activity has slightly increased with several C-class flares, originating from NOAA active region 2230. The strongest flares were C8.1 and C8.6 flares, probably not accompanied by a CME. NOAA 2230 has a beta configuration of it's photospheric magnetic field and it's trailing part has grown in size. No Earth directed CMEs were observed. Flares at the C-level are expected, with an increased chance for M-flares (30% probability). The solar wind speed reached high values (up to 700 km/s) during the first half of the period and then decreased to current values near 530 km/s. The magnitude of the interplanetary magnetic field is stable around 5 nT. A few time slots of active conditions were reached (to 4 for local K at Dourbes and estimated NOAA Kp). Quiet to unsettled magnetic conditions are expected.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 051, gebaseerd op 08 stations.
