Bülletään

Solar activity is very low, without C-class or even B-class flares reported during last 24 hours. We do not expect any significant change in the solar activity, although the isolated, low C-class flares are still possible. No Earth directed Coronal Mass Ejections have been detected, and the solar protons have remained at background levels in the past 24 hours.

This morning solar wind speed started to increase, and it presently amounts about 530 km/s. Simultaneously with the increase of the solar wind speed, increased the temperature and the interplanetary magnetic field strength (presently amounts about 16 nT), while the density decreased. All this indicates arrival of the fast solar wind. Presently the geomagnetic conditions are quiet to unsettled. The arrival of the fast solar wind is expected to induce disturbed geomagnetic conditions in the coming hours (up to K=5).
