Bülletään

Over the past 24 hours solar activity has been low. No significant flares have been recorded. The largest flare was a B3.0 class flare. Active Region (AR) 2663 (Mcintosh class:Dso; Mag. type:Beta) has been most active, producing several B-class flares, however the region is now approaching the West solar limb. 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 and a low probability of M-class flares, but this will diminish as AR 2663 passes over the limb. An AR currently approaching the East solar limb has shown some evidence of activity and should be on disk in the next couple of days and may also enhance activity levels. The solar wind speed has decreased from around 610 to 520 km/s over the past 24 hours. The total magnetic field strength has remained around 5 nT. The Bz component fluctuated around 0 nT, ranging between -5 and +5 nT. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.
