Bülletään

Over the past 24 hours several C-class flares have been detected. The most energetic flares were two C1.9 class flares, produced by NOAA Active Region (AR) 2671. NOAA AR 2672 and Catania Sunspot group 44 produced only B-class flares. No Earth directed Coronal Mass Ejections (CMEs) have been detected. More C-class flares are expected during the next 24 hours, with a small chance of M-class flare.

Geomagnetic conditions have been disturbed due to the long period of negative Bz since early today, Kp reached 4 during 03-09 UT; the local K Dourbes also went up to 4 today. Solar wind speed is increasing again from 04 UT today and currently around 490 km/s. Simultaneously interplanetary magnetic field intensity is increasing and currently around 7.5 nT; Bz is constantly decreasing till actual value of -6 nT. Therefore, more disturbed conditions are expected in the next 24 hours with Kp up to 5.
