Bulletin

Over the past 24 hours solar activity has been low. there were no significant flares and all Active Regions (AR) have shown low levels of activity. There was a small Coronal Mass Ejection (CME) produced by/near AR 2602 (Mcintosh class:Axx; Mag. type:Alpha) which is currently located on the West Solar limb, the CME is not expected to hit the Earth. No Earth directed CMEs have been detected. Solar protons have 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. The solar wind speed has been slowly increasing from 340 to 450 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component fluctuated around 0 nT, between -5 nT and +5 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. A small coronal hole located at central latitudes is currently close to the West limb and the resultant High Speed Stream (HSS) and Co-rotating Interaction Region (CIR) has slightly enhanced solar wind speeds. A chance for slightly enhanced geomagnetic activity should persist throughout the day. A large positive polarity northern coronal hole extending to low latitudes is currently located near disk centre and will enhance solar activity next week.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 017, basierend auf 09 Stationen.
