Bulletin

Solar activity is very low and only B-class flares were reported during the last 24 hours. The largest reported sunspot group, NOAA AR 2396, has the potential to be the source of the C-class flares and possibly but not very probably also the source of an isolated M-class flare. The solar wind speed is currently 520 km/s, and the interplanetary magnetic field magnitude is rather stable having value of about 5nT. The glancing blow from the CME-driven shock wave associated with the partial halo CME, first seen in the SOHO/LASCO C2 field of view at 00:12 UT on August 08, might arrive (although this is not very probable) in the morning of August 11. The geomagnetic conditions are presently quiet and we expect them to remain so in the coming hours.

Today's estimated international sunspot number (ISN): 067, based on 13 stations.
