Bülletään

Over the past 24 hours solar activity has been low. There have been several B-flares flares originated at NOAA AR 2671 (McIntosh: Fai; Mag.Type: Beta-Gamma) and at NOAA AR 2672 (McIntosh: Eai; Mag.Type: Beta- Gamma). The biggest flare B3.7 peaked today (26-Aug-2017) at 02:15 UT. No Earth-directed CMEs have been detected over the past 24 hours. 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 some probability of C-class flares and a very low probability of M-class flares. The solar wind speed has fluctuated around 350 km/s over the past 24 hours. The total magnetic field strength has fluctuated around 5 nT. The Bz component fluctuated between -2.5 and 3.5 nT. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 0-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet for the next 2 days. Quiet to unsettled conditions can be expected on day three (28-Aug-2017) due to the weak influence of a negative polarity CH HSS.
