Over the past 24 hours solar activity has been low. Flaring has been at the B-class level. Active Region (AR) 2615 (Mcintosh class:Cao; Mag. type:Beta) has been most active, producing all the B-class flares. However, The region is now on the West solar limb and will soon pass off the solar disk. No Earth directed Coronal Mass Ejections (CMEs) have been detected, however a front sided partial halo CME was observed heading towards the solar North was seen around 11:00 yesterday in coronagraph observations, however the source region is unclear, and could possibly be a low density, slow, polar crown filament eruption. 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 reasonable chance of C-class flares and a low probability of M-class flares. The solar wind speed has fluctuated between 475 and 750 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 3 nT and 12 nT. The Bz component has fluctuated between -10 and +10 nT. Geomagnetic conditions ranged between Kp index 2-4 (NOAA) and local K index 2-5 (Dourbes) over the past 24 hours, with the enhanced values occurring due to the negative Bz and high speed solar wind generated from a large negative polarity Southern polar trans-equatorial coronal hole (CH). Enhanced solar wind conditions are expected to persist over the next couple of days due to CH High Speed Stream (HSS). As a consequence Geomagnetic conditions are expected to be quiet to unsettled for the next few days.
