Bulletin

Flaring activity remains low. The strongest flare today was a C1.7 flare occurring in NOAA AR 2132 with peak time 11:30 UT. We expect further flaring at the C-class level, especially from NOAA AR 2130 and 2132, with a small chance for an isolated M-class flare. No earth-directed CMEs were observed since our last bulletin. Still under the influence of a coronal hole high speed stream, the solar wind speed has increased up to 450 km/s, while the total magnetic field strength is currently at 6.4 nT. Geomagnetic conditions remain unsettled (k up to 3). We expect a return to quiet conditions in the coming hours. On August 7 unsettled conditions may occur due to the possible arrival of another coronal hole wind stream.

Today's estimated international sunspot number (ISN): 092, based on 17 stations.
