Bulletin

Over the past 24 hours solar activity has been low, there have been no C, M or X-class flares recorded. NOAA Active Region (AR) 2453 (N10E10 Bxo/Beta) has shown some growth, but remains small and appears stable. All other ARs have remained stable with small amounts of flux emergence. A small centrally located filament has shown some movement and has the potential to erupt. There were no Earth directed Coronal Mass Ejections (CMEs) observed over the past 24 hours. Solar activity is expected to remain low with a chance of C-class flares. The solar wind speed has increased slightly over the past 24 hours, from around 400 km /s to around 460 km /s. The total magnetic field slowly decreased from around 10 nT to 5 nT over the past 24 hours. The Bz component has oscillated between -5 nT and +6 nT over the past 24 hours. Geomagnetic conditions have been mainly quiet over the past 24 hours (NOAA Kp 3-2, local K Dourbes 1-3). A small positive polarity coronal hole (CH) high-speed stream (HSS) enhanced geo-activity slightly yesterday (2015-Nov-13), and continued through the night.
