Bulletin

Enhanced geomagnetic conditions are imminent 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.

Today's estimated international sunspot number (ISN): 062, based on 20 stations.
