Bulletin

The solar activity has been quiet over the past 24 hours, with the X-ray flux remaining below B-class level. The probability of C-class flares occurring remains very low and quiet conditions are expected to continue over the next 24 hours.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10MeV proton flux remained at background levels over the past 24 hours and is expected to remain so.

Over the last 24 hours the solar wind began to slowly decrease from 530 to 450 km/s. The total magnetic field strength fluctuated around 4.0 nT, while the Bz component fluctuated between -3.0 and 3.5 nT. The slightly enhanced solar wind conditions are expected to continue over the next 24 hours before gradually decreasing as the Earth leaves the influence of the solar wind stream associated with the extended southern polar coronal hole, which first crossed the central meridian on the 10th of February.

The geomagnetic conditions were quiet to unsettled over the last 24 hours, with the Kp (NOAA) and the local K (Dourbes) indices ranging between 0-3. The geomagnetic conditions are expected to continue to be unsettled as the enhanced solar wind associated with the extended southern polar coronal hole continues to influence the Earth over the coming hours.

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