Bulletin

Over the past 24 hours solar activity has been very low. The visible solar disc was spotless and no significant flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph imagery. The greater than 10MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain very low over the next 24 hours.

The solar wind fluctuated between 320 km/s and 380 km/s over the last 24 hours. The total magnetic field strength fluctuated between 3.1 and 6.7 nT. The Bz component ranged between approximately -6 and +4 nT. The phi angle was predominantly in the negative sector.

Geomagnetic conditions have been quiet over the past 24 hours, with Kp index (NOAA) and local K index (Dourbes) both ranging between 1 and 2. Quiet geomagnetic conditions are expected over the next 24 hours, with the possibility of isolated unsettled periods due to the weak solar wind stream associated with a small negative polarity coronal hole, which traversed the central meridian on 21 May.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 24 Stationen.
