Bulletin

Solar X ray flux remained below B level. The newly numbered region (NOAA 2702) has remained quiet and appears stable. Solar X-ray flux is still expected to remain below C level.

No Earth directed CMEs have been observed in coronagraph data.

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

Solar wind remained enhanced with solar wind speed between 475km/s and 525 km/s. Total magnetic field was mainly nominal with a maximum of 7nT. The magnetic field phi angle seems to have switched into a positive sector at the start of the period. Enhanced solar wind conditions are expected to continue at least today before beginning to subside.

Geomagnetic conditions were quiet to unsettled (local K Dourbes and NOAA Kp 1-3). Active geomagnetic conditions could still occur today and into tomorrow.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 008, gebaseerd op 07 stations.
