We expect solar activity to stay at eruptive levels with risks of C class flares essentially from NOAA ARs 1817 and 1818. A small eruption occurred to the west of AR 1817 on Aug. 13, around 1230 UT. It was associated with a CME which appeared to be non geoeffective. Geomagnetic activity is expected to be mostly unsettled for the next 24 hours, as the Earth entered a fast wind stream linked to a coronal hole in geoeffective position. Current observations by the ACE spacecraft show a solar wind speed around 450 km/s and Bz fluctuations diminishing compared to the last 20 hours.
Today's estimated international sunspot number (ISN): 074, based on 15 stations.
