Bulletin

No active regions visible on the disk. Solar activity has been very low, no flares in the past 24 h. The situation is not expected to change in the next 48 h.

No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 520 km/s with interplanetary magnetic field magnitude of 3 nT. Geomagnetic conditions ranged between 2 and 4 (both for Kp and K Dourbes). The active periods observed early today were due to slightly high speed solar wind (~550 km/s) with negative Bz (up to -5 nT), lasting for several hours. The fast solar wind stream associated with a negative polarity coronal hole is expected to arrive to the Earth on September 7. Quiet to unsettled geomagnetic conditions expected until then.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 24 stations.
