Bülletään

Over the past 24 hours solar activity has been low. The visible solar disc was spotless and the X-ray flux remained below B-class level. 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 low over the next 24 hours.

The solar wind speed has fluctuated between around 345 and 405 km/s over the past 24 hours. The total magnetic field strength fluctuated between 0.6 and 5 nT. The Bz component ranged between approximately -3 and +3 nT. The phi angle was positive until 8 UT this morning (22 May) when it switched into 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 0 and 2. Quiet to unsettled geomagnetic conditions are expected over the next 24 hours, due to the weak solar wind stream associated with a series of small negative polarity coronal holes.
