Bulletin

Solar X-ray flux remained below the B level throughout the period. The two regions on disk are simple and quiet and X ray flux is expected to remain below C level over the next days. Proton flux levels were at background values and are expected to remain so. No Earth directed CME's were recorded in coronagraph data.

Solar wind saw a further recovery to nominal conditions. Solar wind speed declined to below 400 km/s while total magnetic field was around a nominal 5nT with the Bz component variable. Nominal Solar wind conditions are expected over the next days. Geomagnetic conditions were quiet (local K Dourbes 1-2, NOAA Kp 0-2) and are expected to remain so over the next days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 025, gebaseerd op 14 stations.
