Bulletin

The strongest flare reported during last 24 hours was the C1.0 flare peaking at 15:15 UT, on August 11. We expect B-class flares and possibly also an isolated C-class flare in the coming hours, in particular from the NOAA AR 2396 and rather fast growing NOAA AR 2400. No Earth directed CMEs were observed during last 24 hours.

The Earth is currently inside the slow solar wind. The with speed is fluctuating between 370 and 430 km/s, and the interplanetary magnetic field magnitude is about 7nT. The fast flow from the equatorial coronal hole, which reached the central meridian this morning, might arrive on August 15. The geomagnetic conditions are presently quiet and we expect them to remain so in the coming hours.

Today's estimated international sunspot number (ISN): 066, based on 14 stations.
