Bülletään

Over the past 24 hours solar activity has been quiet. No significant flares have been recorded. All Active Regions (AR) have shown low levels of activity. No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10 MeV proton flux remained at background levels over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares. The solar wind speed fluctuated between 350 and 450 km/s over the past 24 hours, peaking around 00:00 UT this morning. The total magnetic field strength has fluctuated between 3 and 10 nT, peaking around 00:00 UT this morning. The Bz component has fluctuated between -6 and +8 nT. Geomagnetic conditions ranged between Kp index 0-4 (NOAA) and local K index 0-5 (Dourbes) over the past 24 hours. The enhanced solar wind speed and negative Bz this morning resulted in a peak in geo-magnetic conditions (K=5). A small transient coronal hole has just passed the central meridian and will enhance solar wind speeds in a couple of days. Geomagnetic conditions are expected to be quiet to unsettled.
