Bulletin

Over the past 24 hours solar activity has been low. No significant flares have been recorded. No Active Regions (AR) are present on the disk. 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 near disk centre. 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 fluctuated between 460 and 360 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 2 nT and 5 nT. The Bz component was largely positive, fluctuating between -2.5 and +3.5 nT. Geomagnetic conditions ranged between Kp index 0-1 (NOAA) over the past 24 hours. There is currently a negative polarity low latitude northern polar coronal hole which has moved into the western hemisphere and may increase solar wind speeds over the coming days. Geomagnetic conditions are expected to be quiet before becoming unsettled with the arrival of the high-speed stream (HSS) associated with the coronal hole.
