Bulletin

Solar activity was very low with X-ray flux remaining below B level and no spots on the visible disk. This is expected to remain so over the next days.

No Earth directed CMEs have been recorded in coronagraph images.

Proton flux levels were at background values and are expected to remain so.

Solar wind conditions were near nominal. Solar wind speed was between 390 and 440 km/s, and is currently around 400 km/s. Total magnetic field was 2-6nT with Bz variable. The magnetic field phi angle was in the positive sector. Solar conditions are expected to remain near nominal over the next days.

Geomagnetic conditions were quiet to unsettled (NOAA Kp as well as local K Dourbes 1-3). Generally, quiet conditions are expected over the next days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 23 stations.
