Bulletin

Over the past 24 hours solar activity has been quiet. No significant flares have been recorded. Active Region (AR) 2696 (Mcintosh class:Bxo; Mag. type:Beta) is the only region on the disk, producing a B9.7 class flare. Flaring activity from the region has been increasing. There are no other significant ARs on the solar disk. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar activity is expected to remain low over the next 24 hours with a chance of C-class flares. The solar wind speed has fluctuated around 350 km/s over the past 24 hours. The total magnetic field strength has remained around 5 nT. The Bz component has been mainly positive ranging between -1 and +5 nT. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index 0-1 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet, however a coronal hole is currently passing disk centre and may increase geomagnetic activity in 2-3 days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 014, gebaseerd op 12 stations.
