Bulletin

Over the past 24 hours solar activity has been quiet. No significant flares have been recorded. Active Region (AR) 2696 (Mcintosh class:Cro; Mag. type:Beta) is the only region on the disk, but has been quiet. 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 small probability of C-class flares. The solar wind speed has decreased from around 440 to 350 km/s over the past 24 hours. The total magnetic field strength has remained around 5 nT. The Bz component fluctuated around 0 nT, ranging between -4 and +4 nT. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 017, gebaseerd op 12 stations.
