Bülletään

Over the past 24 hours solar activity has been low. The largest flare was a C1.7 class flare. Active Region (AR) 2645 (McIntosh class:Ekc; Mag.type:Beta-Gmma) has been most active, producing 2 C-class flares, including the C1.7 class flare, which peaked at 17:37 UT yesterday. All other ARs have shown low levels of activity. AR 2645 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 decreased from 700 till 580 km/s over the past 24 hours. The total magnetic field strength has fluctuated between 4 nT and 5.5 nT. The Bz component fluctuated between -4.2 and +5 nT. Geomagnetic conditions ranged between Kp index 2-3 (NOAA) and local K index 2-4 (Dourbes) over the past 24 hours. There are no significant trans-equatorial coronal holes. Geomagnetic conditions are expected to be unsettled to active.
