Bulletin

Over the past 24 hours solar activity has been quiet. 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 chance of C-class flares. The solar wind speed has increased from around 325 to around 375 km/s over the past 24 hours. The total magnetic field strength has increased from around 5 to 9 nT. The Bz component has ranged between -6 and +6 nT. Geomagnetic conditions ranged between Kp index 0-3 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. Geomagnetic conditions may increase as a coronal hole has passed into the Western hemisphere and may increase geomagnetic activity later today.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 013, basierend auf 13 Stationen.
