Bulletin

Solar X-ray flux remained below B level. There are no spotted regions on disk and Solar flaring is expected to remain below C level over the next days.

There were no Earth directed Coronal Mass Ejections (CMEs) observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels. The greater than 2 MeV electron flux has been slightly enhanced over the past 24 hours. The electron flux should be at background values over the next days as Solar wind has returned to a nominal slow Solar wind regime.

Solar wind returned to a nominal slow Solar wind regime. Solar wind speed dropped steadily from around 420 km/s to around 370 km/s currently. Total magnetic field was at or around 5nT wit a variable Bz component. The magnetic field phi angle was stable in the towards sector. Solar wind conditions are expected to remain nominal.

Geomagnetic conditions were quiet to unsettled (NOAA Kp and local K Dourbes 0-3). Quiet geomagnetic conditions are expected over the next days, with possibly some isolated unsettled episodes.

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