Bulletin

Over the past 24 hours solar activity has been low. There has been one B-class flare. Active Region (AR) 2615 (Mcintosh class:Hsx; Mag. type:Alpha) has now moved over the West solar limb. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours. There are no significant Active Regions (AR) on the sun, therefore 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 fluctuated between 525 and 725 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component has fluctuated between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 3-5 (NOAA) and local K index 2-5 (Dourbes) over the past 24 hours, with the enhanced values occurring due to fluctuating Bz and high speed solar wind generated from a large negative polarity Southern polar trans-equatorial coronal hole (CH). Enhanced solar wind conditions are expected to persist over the next couple of days due to the CH High Speed Stream (HSS). As a consequence Geomagnetic conditions are expected to be unsettled to active for the next couple of days, with a possibility of minor storms.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 12 Stationen.
