Bülletään

Active Region (AR) 2671 (McIntosh class: Fsi; Mag.type: Beta- Gamma) and AR 2672 (McIntosh class: Esi; Mag.type: Beta-Gamma) produced three C-class flares during the past 24 hours. The largest flare was C2.2 flare peaking at 13:43 UT yesterday. No Earth directed Coronal Mass Ejections (CMEs) have been detected. The greater than 10MeV proton flux remained at background levels over the past 24 hours. There are no potentially geoeffective coronal holes on the Sun. More C-class flares are expected over the next 24 hours. Solar wind parameters remained elevated over the past 24 hours. Total interplanetary magnetic field strength varied between 2 and 9 nT. The Bz component was mostly negative with a maximum southward deflection of -7.5 nT. Solar wind speed slightly decreased from about 620 till 413 km/s (at 12:30 UT) over the past 24 hours. Geomagnetic conditions have been disturbed due to the long period of negative Bz; Kp reached 5 at 15 UT and returned to Kp = 3 at 21 UT yesterday; the local K Dourbes also went up to 4. The geomagnetic environment is expected to be at unsettled to active levels today and tomorrow.
