Bulletin

Over the past 24 hours solar activity has been quiet. No significant flares have been recorded. All Active Regions (AR) have shown low levels of activity. 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. The solar wind speed has been decreasing from around 450 to 330 km/s over the past 24 hours, with a small increase this morning. The total magnetic field strength has fluctuated around 5 nT. The Bz component has fluctuated between positive and negative, between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet. Although it is not expected, if solar wind speeds continue to increase we could experience enhanced geomagnetic conditions as a consequence.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 17 Stationen.
