Bulletin

There are five active regions observed on the visible side of the solar disc. Only one C-class flare and several B-class flares were reported during last 24 hours. The C2.4 flare (peaked at 16:44 UT on August 11) originated from the NOAA AR 2574. We expect solar activity to remain low, with possibility of isolated C-class flares. No Earth directed CMEs were observed in the last 24 hours. The Earth is still inside the fast solar wind, but the solar wind speed started to decrease and it currently amounts about 530 km/s. The interplanetary magnetic field is stable and amounts about 5 nT. The geomagnetic conditions are presently quiet to unsettled, and we expect them to stay so in the coming hours.

Today's estimated international sunspot number (ISN): 078, based on 17 stations.
