Bulletin

There are two active regions visible on the solar disk, with alpha magnetic field configuration and one sunspot each. No C-class flares in past 24 h. Solar activity is expected to remain at low levels.

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 620 km/s with interplanetary magnetic fields of 4 nT. The Earth is under the influence of a high speed solar wind stream. Geomagnetic conditions have been quiet to unsettled. For the next 48h unsettled to active periods can be expected (with isolated minor storm periods possible).

Today's estimated international sunspot number (ISN): 014, based on 14 stations.
