Bulletin

Over the past 24 hours solar activity has been low with no active 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 has reached the 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 350 to 450 km/s during the first half of the period. Later solar wind speed growth stabilized around 420 km/s. The total magnetic field strength has fluctuated between 2 nT and 9 nT. The Bz component has fluctuated between -6 nT and +7 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Mostly quiet to unsettled geomagnetic levels are expected today and tomorrow. Active conditions can be expected most likely from April 8 afternoon due to the influences of a high speed stream coming from the low-latitude negative polarity coronal hole.
