Over the past 24 hours solar activity has been low. Flaring has been at the B-class level. Active Region (AR) 2615 (Mcintosh class:Cso; Mag. type:Beta) has been most active, producing all the B-class flares. However, The region is now approaching the West solar limb and will soon pass off the solar disk. AR 2615 has shown some evidence of flux emergence and cancellation in HMI magnetogram observations, and is expected to continue producing flaring activity. No Earth directed Coronal Mass Ejections (CMEs) have been detected, but a large filament eruption occurred close to the East solar limb, but is not expected to interact with the Earth system. 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 330 and 600 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 5 nT and 20 nT. The Bz component has fluctuated between -10 and +20 nT. Geomagnetic conditions ranged between Kp index 2-4 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours, with the slightly 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). This region will be creating enhanced solar wind conditions over the coming days due to influences from the associated Co-Rotating-Interaction Region (CIR) and the subsequent CH High Speed Stream (HSS). As a consequence Geomagnetic conditions are expected to be quiet to unsettled for the next few days.
