Bulletin

Enhanced geomagnetic conditions are expected as a result from a high speed solar wind outflow from a recurrent coronal hole in the Southern solar hemisphere. Meanwhile, the flaring potential of NOAA active region 1726 is decreasing, yet major C-flares are still possible. The proton flux levels are further decreasing and returning to background levels.

Today's estimated international sunspot number (ISN): 047, based on 07 stations.
