Bulletin

During last 24 hours there were no C-class or even B-class flares reported. The only sunspot group, observed on the visible side of the Sun, Catania sunspot group 19 (NOAA AR 2743) is rotating behind the west solar limb. We do not expect flaring activity of the B-class level or larger in the coming hours. There were no Earth directed CMEs and the solar protons remained at the background level.

The solar wind speed is presently about 380 km/s and the interplanetary magnetic field magnitude is 3 nT. The geomagnetic conditions are quiet and we expect them to stay so in the coming hours.

Today's estimated international sunspot number (ISN): 000, based on 25 stations.
