Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. No Active Regions (AR) are present on the disk. 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. A low latitude coronal hole is currently located in the western hemisphere. 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 around 340 to 470 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 3.0 nT and 12.0 nT. The Bz component has fluctuated between -10.0 and +8.0 nT. Geomagnetic conditions ranged between Kp index 1-4 (NOAA) over the past 24 hours. A low latitude negative polarity northern polar coronal hole has caused increased solar wind speeds at Earth and combined with negative Bz has enhanced geomagnetic activity, which may persist over the next few hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 11 Stationen.
