Bulletin

Over the past 24 hours solar activity has been very low. The largest flare was a B8.2 class flare, produced by Active Region (AR) 2542 (Gai:Beta), which peaked at 14:22 UT today. There are three other inactive ARs on the solar disk (AR 2543, AR 2544, AR 2545). No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a probability of C-class flares. The solar wind parameters variations are decaying after the influence of the negative polarity coronal hole effects. The solar wind speed has decreased till approximately 400 km/s over the past 24 hours. The total magnetic field strength magnitude has decreased till 4-5 nT. The Bz component of magnetic field has been mostly negative over the past 24 hours, varying between +2 and -4 nT. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic activity is expected to remain low within next 2 days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 083, gebaseerd op 16 stations.
