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 identified in coronagraph images.

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

Solar wind remained slightly elevated with solar wind speed within the 400-450 km/s range. Total magnetic field was 2-7nT with Bz variable. The magnetic field phi angle was mainly in the negative sector but seems to have switched into the positive sector recently. Solar wind speed is expected to remain slightly enhanced and may possible slightly increase under the influence of some patchy negative polarity open fields in the Southern hemisphere near the equator.

Geomagnetic conditions were quiet to unsettled (NOAA Kp 1-3 and local K Dourbes 1-2) and are expected to remain so.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 26 stations.
