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. AR 2664 (Mcintosh class:Hsx; Mag. type:Alpha) appears complex in HMI magnetogram observations and has shown some evidence of activity, producing several small narrow CMEs which may enhance activity levels in the coming days. There's a small centrally located filament channel which looks stable, and a small northern coronal hole located at high latitudes and central longitudes, which is unlikely to significantly affect the Earth system but may enhance solar wind speeds in several days. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares and a very low probability of M-class flares. The solar wind speed has fluctuated around 350 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 5 and 8 nT. The Bz component fluctuated around -5 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 024, gebaseerd op 23 stations.
