Bulletin

There are currently 4 numbered AR on the solar disk. A solitary C2.0 flare occured on August 9th around 20:10 UT from an unnumbered AR on the East limb. A small increased solar wind speed up to 480 km/s was detected by ACE, probably due to a very small coronal hole which was associated with a passing of the current sheet. Geomagnetic where quiet and are expected to remain so for the next 24 hours. In the night of August 11th-August 12th we expect active conditions due to the arrival of the CME of August 7th.

Today's estimated international sunspot number (ISN): 046, based on 11 stations.
