Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. Active Region (AR) 2699 (Mcintosh class:Cao; Mag. type:Beta) has been most active, showing considerable flux emergence and cancellation, but is now approaching the western limb. The greater than 10MeV proton flux remained at background levels over the past 24 hours. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Over the next 24 hours there is a small chance of C-class flares. The solar wind speed fluctuated around 375 km/s over the past 24 hours. The total magnetic field strength has increased from around 5 nT to 15 nT, the Bz component has fluctuated between -5 and +15 nT. Geomagnetic conditions ranged between Kp index 1-4 (NOAA) and local K index 1-4 (Dourbes) over the past 24 hours. A High Speed Stream (HSS) associated with a large coronal hole that passed the central meridian a couple of days ago may enhance solar wind conditions over the next couple of days. Geomagnetic conditions are expected to be quiet to unsettled.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 013, basierend auf 19 Stationen.
