Bulletin

Over the past 24 hours solar activity has been very low. No significant 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. Quiet flaring conditions are expected to continue. The solar wind speed has increased from around 413 to 340 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 1 nT and 5 nT. The Bz component fluctuated around 0 nT, ranging between -3 and +3 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. There is currently a small positive polarity Northern polar coronal hole which has moved into the Western hemisphere and may increase solar wind speeds over the coming days, but only a small enhancement is expected. Geomagnetic conditions are expected to be quiet to unsettled.
