Bulletin

No active regions on the visible solar disc. No C-class flares in past 24 h and the situation is not expected to change.

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

The solar wind speed at L1 is at 350 km /s with interplanetary magnetic field magnitude of 4 nT. Geomagnetic conditions are quiet, the high speed solar wind from a negative polarity coronal hole located in the southern hemisphere is expected to arrive to the Earth in about 24 h and cause disturbed geomagnetic conditions (up to minor storm level).

Today's estimated international sunspot number (ISN): 000, based on 23 stations.
