Bulletin

With no spotted regions on disk, no Solar flaring activity was recorded and this is expected to remain so. No Earth directed CMEs have been observed in coronagraph data. Solar proton fluxes are at background values and are expected to remain so.

Solar wind saw the continued influence of a coronal hole high speed stream. Solar wind speed declined from a peak over 700 km/s to around 550 km/s presently. Total magnetic field remained around 7nT throughout the period. Bz was mostly variable but saw some excursions to -7nT. Over the next 2 days we should see a return to nominal Solar wind conditions. Geomagnetic conditions were quiet to active (both local K Dourbes and NOAA Kp 1-4) with only a limited number of active periods. Geomagnetic conditions are expected to be quiet to unsettled over the next days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 18 stations.
