Bulletin

Solar flaring activity was at very low levels. No significant flares have been recorded. Solar activity is expected to remain at very low levels.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to stay at nominal levels in the next 24 hours.

The solar wind speed near Earth showed a generally decreasing trend with values ranging between 440 and 530 km/s (DSCOVR) over the past 24 hours. The magnitude of the Interplanetary Magnetic Field (IMF) varied between 1 and 6 nT and the phi angle was predominantly in the negative sector with some extended deviations into the positive sector on Mar 23. Bz ranged between -4 and +3 nT. Slightly enhanced solar wind conditions are expected in the next 24 hours before gradually returning to an ambient solar wind regime.

Quiet to active geomagnetic conditions were registered for the past 24 hours (K Dourbes and NOAA Kp recorded values of between 1-4 and 1-3, respectively). Quiet to unsettled geomagnetic conditions are expected on March 24 to 26, with a chance for isolated active intervals (K Dourbes = 4) in the next 24 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 29 Stationen.
