Bulletin

Over the past 24 hours solar activity has been low. The largest flare was a B1.7 class flare. Active Region (AR) 2615 (Mcintosh class:Dai; Mag. type:Beta) has been most active, producing B-class flares. All other ARs have shown low levels of activity. AR 2615 has shown some evidence of flux emergence and cancellation in HMI magnetogram observations, this may increase flaring activity. No Earth directed Coronal Mass Ejections (CMEs) have been detected. 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 a high probability of C-class flares and a low probability of M-class flares. The solar wind speed has fluctuated between 275 and 350 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 2 nT and 10 nT. The Bz component was largely positive, but turned negative earlier today fluctuating between -10 and +10 nT. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. There are no significant trans-equatorial coronal holes. Geomagnetic conditions are expected to be quiet to unsettled.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 033, na základě 19 stanic.
