Bülletään

Active Region (AR) 2672 (McIntosh class: Esi; Mag.type: Beta- Gamma) produced C5.5 flare peaking at 07:27 UT today. AR 2671 (McIntosh class: Fsi; Mag.type: Beta-Gamma) produced multiple B-class flares during the past 24 hours; the largest flare was B8.4 flare peaking at 15:58 UT yesterday. No Earth directed Coronal Mass Ejections (CMEs) have been detected in available coronagraph imagery. Solar activity is expected to be at C-class flaring level for the next three days. Solar wind parameters variations decayed over the past 24 hours. The solar wind speed decreased from 410 to 350 km/s. The total magnetic field strength remained below 5.5 nT. The Bz component fluctuated around 0 nT but was mainly positive, ranging between -3.5 and +4 nT. Geomagnetic conditions ranged between Kp index 1-3 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be mostly quiet with some isolated episodes of Kp=3.
