Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. There are currently no Active Regions on the solar disk. 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 solar activity is expected to be low. The solar wind speed has increased from around 475 to 600 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 6 nT, the Bz component has fluctuated between -5 and +6 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 has enhanced solar wind speeds, but should abate over the next 24 hours. Geomagnetic conditions are expected to be quiet to unsettled.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 19 Stationen.
