Bulletin

The strongest solar event of the past 24 hours was a C1.9 flare originating from NOAA AR 1817 at 9h22 UT. We expect solar activity to stay at eruptive levels with chances for C class flares mainly from NOAA ARs 1817, 1818 and 1824 and a small risk for an isolated M class flare. An increase in the solar wind speed is expected due to the effects of the recurrent equatorial CH high-speed stream. Enhanced geomagnetic activity is possible (unsettled to active) for the next two days, in relation to the CH and the possible arrival of the CME of August 17.

Today's estimated international sunspot number (ISN): 091, based on 16 stations.
