Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. Active Region (AR) 2701 (Mcintosh class:Axx; Mag. type:Alpha) emerged near disk centre but is compact and has shown no significant flaring activity. 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. A low latitude coronal hole is currently located in the western hemisphere. Solar activity is expected to remain low over the next 24 hours with a low probability of C-class flares. The solar wind speed has been fluctuating around 500 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 3.0 nT and 8.0 nT. The Bz component has been mainly negative fluctuated between -6.0 and +5.0 nT. Geomagnetic conditions ranged between Kp index 1-4 (NOAA) over the past 24 hours. A low latitude negative polarity northern polar coronal hole has caused increased solar wind speeds at Earth and enhanced geomagnetic activity, which may persist throughout the next couple of days.
