Bülletään

Over the past 24 hours solar activity has been low with no spotted regions on the solar disk. No flares have been recorded. No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10MeV proton flux remained at background levels over the past 24 hours. A low latitude negative polarity coronal hole currently located in the eastern hemisphere is approaching central meridian. Solar activity is expected to remain low over the next 24 hours. Only B-class flares can be expected. The solar wind speed has been slowly increasing from around 330 to 380 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 1 nT and 7 nT. The Bz component has fluctuated between -3 nT and +4.5 nT. Geomagnetic conditions ranged Kp index between 1-3 (NOAA) and local K index between 1-3 (Dourbes) over the past 24 hours. Mostly quiet to unsettled geomagnetic levels are expected today and tomorrow. Active conditions can be expected from April 7 (late) due to the influences of a high speed stream coming from the low-latitude negative polarity coronal hole.
