Bulletin

Over the past 24 hours solar activity has been quiet. No significant flares have been recorded. A small bipolar region has emerged at S14E45 and is showing some evidence of growth that may increase flaring activity over the next 24 hours. There are no other significant Active Regions (AR) on the solar disk. There's a small filament channel located in the South-West, but appears stable. No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar activity is expected to remain low over the next 24 hours with a small probability of C-class flares. The solar wind speed has decreased from around 575 to 500 km/s over the past 24 hours. The total magnetic field strength has remained around 6 nT. The Bz component fluctuated around 0 nT, ranging between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 1-4 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.

Today's estimated international sunspot number (ISN): 007, based on 06 stations.
