Bülletään

Over the past 24 hours solar activity has been low. No significant flares have been recorded. Catania group 56 / NOAA AR region 2682 (McIntosh: Cso; Mag.Type: Beta) has been most active, producing one B3.5 flare peaking at 17:11 UT yesterday (30-Sep-2017). No Earth directed Coronal Mass Ejections (CMEs) have been detected in coronograph observations. Integral proton flux for protons with energies above 10 MeV remained at background level over the past 24 hours. Solar activity is expected to remain low over the next 24 hours with some probability of C-class flares. Solar wind speed continues overall decline from about 540 km/s to 490 km/s, reflecting declining influence from the high speed stream from the positive polarity coronal hole. The interplanetary magnetic field magnitude returned to its nominal 4-5 nT range with the Bz component fluctuating between -4.5 and 4.5 nT. The solar wind is expected to further recover to background conditions over the next days. Geomagnetic conditions were quiet to active (local K Dourbes 1-4, NOAA Kp 2-4) and are expected to remain quiet to unsettled over the next days. Isolated periods of active conditions are possible.
