There is a small risk for C class flares from NOAA ARs 1817, 1818 and 1819, keeping the solar activity level to eruptive. A southern polar crown filament erupted on August 14, around 1900UT. It was associated with a CME, which appears not to be geoeffective. Geomagnetic activity is expected to remain at unsettled levels for the next 24 hours, and then to return to quiet conditions on Aug. 17. Current ACE observations show that the Earth is still within a fast solar wind stream linked to the northern coronal hole on the Sun.
Today's estimated international sunspot number (ISN): 084, based on 11 stations.
