Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. 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 and a very low probability of M-class flares. Active Region (AR) 2663, which produced several B-class flares, is approaching the west limb. An AR currently on the east solar limb has shown some evidence of activity, producing several small CMEs which may enhance activity levels in the coming days. The solar wind speed has decreased from around 500 to 400 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 3 and 4 nT. The Bz component fluctuated around 0 nT. Geomagnetic conditions ranged between Kp index 0-2 (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: 033, gebaseerd op 25 stations.
