Bülletään

Over the past 24 hours solar activity has been low. There have been several B-flares flares originated at NOAA AR 2659 (McIntosh: Dai; Mag.Type: Beta). The biggest flare B2.9 peaked yesterday (26-Mar-2017) at 21:23 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 X-Ray background level is expected to remain low. NOAA AR 2659 and one returning active region are expected to produce more B-class flares over the next 24 hours. C class flares are also not excluded. The variations of the solar wind parameters were weak. Solar wind speed remained below 310 km/s during the last 24 hours. The magnitude of the Interplanetary Magnetic Field (Bt) remained below 5 nT. The Bz component fluctuated between between -3 and +3 nT. Geomagnetic conditions have been very quiet in the past 24 hours (K Dourbes between 0 and 2; NOAA Kp between 0 and 2). Geomagnetic activity is expected to continue at very low levels today (27-May-2016). Active conditions are still possible from today midnight due to the possible arrival of the 23-May-2017 CME.
