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 was at background levels over the last 24 hours, with a minimum and maximum speed recorded of around 295 km/s and 355 km/s, respectively. The total magnetic field strength fluctuated between 0.4 and 5.7 nT. The Bz component ranged between approximately -3 and +4 nT. The phi angle was predominantly negative, switching to the positive sector at around 4 UT.

Geomagnetic conditions have been quiet to unsettled over the past 24 hours, with Kp index (NOAA) and local K index (Dourbes) ranging between 0-2 and 0-3, respectively. Quiet geomagnetic conditions are expected over the next 24 hours, with the possibility of isolated unsettled intervals.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 21 Stationen.
