Over the past 24 hours solar activity has been very low. No significant flares have been recorded. All Active Regions (ARs) have shown low levels of activity, however AR 2632 (Mcintosh class:Dao; Mag. type:Beta) has shown some evidence of growth. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have 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 and a very low probability of M-class flares. A large negative polarity trans-equatorial coronal hole extending from the Southern pole is currently located in the Western hemisphere. The solar wind speed been slowly decreasing and fluctuated between 750 and 600 km/s over the past 24 hours. The total magnetic field strength has been around 5 nT. The Bz component fluctuated between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 3-4 (NOAA) and local K index 1-4 (Dourbes) over the past 24 hours. The high speed stream (HSS) associated with the large negative polarity trans-equatorial coronal hole extending from the Southern pole is the cause of the increased solar wind speeds creating active Geomagnetic conditions. The enhanced solar wind speed is expected to create intermittent active geomagnetic conditions over the next couple of days, but should begin to abate.
