Bulletin

There are currently eight sunspot regions on the visible disk. Flaring activity was restricted to two C1 flares, originating from Catania sunspot regions 79 and 81 (NOAA active regions 2360 and 2362). C-class flares are expected from these regions, with some slight chance for flares at the M-level. No Earth-directed CMEs were observed.

Solar wind observations indicate the arrival of the expected arrival of the negative polarity coronal hole high speed stream. Solar wind speed started to rise around 0:00 UT from 400 km/s and reached 700 km/s. The magnitude of the magnetic field peaked at 23 nT around 5:00 UT, but has now declined to 6 nT. The north-south component Bz was fluctuating with values down to -21 nT. Moderate geomagnetic storm conditions were recorded at planetary level (NOAA Kp=6 in the 09-12UT slot), while at local level (at Dourbes) K currently reaches 5. Further periods of active geomagnetic conditions are to be expected for the next 24 hours subject to the orientation and magnitude of the magnetic field, before returning to quiet levels again.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 091, gebaseerd op 19 stations.
