Bülletään

There is one active region visible on the solar disk (NOAA 12735 with beta magnetic field configuration). No C-class flares in past 24 h. Solar activity is expected to remain low.

No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 375 km/s with interplanetary magnetic fields of 6 nT. Geomagnetic conditions have been quiet in the past 24 h. In the last hours, density and interplanetary magnetic field started to increase, together with a change of negative to positive IMF polarity. These are most likely signs of the compression region in front of the high speed solar wind stream expected for today. Unsettled to active geomagnetic conditions can be expected (with possible isolated minor storm conditions).
