Bulletin

During last 24 hours, only reported flaring activity were two low B-class flares. We do not expect change of the level of the flaring activity in the coming hours. Coronagraph images do not show signatures of the Earth directed CMEs, and the solar protons are at the background level.

The maximum value of the solar wind speed, during last 24 hours, was reached at about 23:30 UT on June 26, and it amounted about 670 km/s. The solar wind speed is slowly decreasing and its present value is 550 km/s. The interplanetary magnetic field magnitude amounts about 5 nT. The geomagnetic conditions are presently quiet to unsettled and we expect such geomagnetic conditions to persist in the coming hours.

Today's estimated international sunspot number (ISN): 012, based on 26 stations.
