Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. There are currently no significant Active Regions on the solar disk. No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares and a low probability of M-class flares.

The solar wind speed fluctuated between 375 to 320 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 3 nT. The Bz component fluctuated around 0 nT, ranging between -4 and +4 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. A small low latitude coronal hole passed the central meridian today and could increase solar wind speeds at Earth in a couple of days. Geomagnetic conditions are expected to be quiet to unsettled.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 14 stations.
