Bülletään

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 crossed the central meridian yesterday. Solar activity is expected to remain low over the next 24 hours. Only B-class flares can be expected. Solar wind paremetrs variations have been very low. The solar wind speed is below 370 km/s. The total magnetic field strength has fluctuated between 1.5 nT and 3.5 nT. The Bz component has fluctuated between -3.5 nT and +3.5 nT. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. Mostly quiet to geomagnetic levels are expected today and tomorrow morning. Unsettled and even active conditions can be expected from tomorow evening (April 8) due to the influences of a high speed stream coming from the low-latitude negative polarity coronal hole.
