Bulletin

Over the past 24 hours solar activity has been low. The largest flare was a C 1.5 class flare, produced by Active Region (AR) 2529 (Dhi;Beta), which peaked at 05:30 UT this morning. Another region AR 2528(Bxo,Beta) is currently moving onto the West limb. A slow Coronal Mass Ejection (CME) has been detected yesterday at 22:30 UT, which evolved from a small filament eruption at the western limb. 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 increased likelihood on C-class flares and small probability of M-class flares. The solar wind parameters perturbations are decaying after the sector boundary crossing 2 days ago. The solar wind speed has decreased till approximately 350 km/s over the past 24 hours. The total magnetic field strength magnitude has decreased till 5-6 nT. The Bz component of magnetic field has been mostly positive over the past 24 hr and decreased till 4-5 nT in magnitude. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic activity is expected to remain low within next 2 days.
