Bulletin

There are presently two small and simple sunspot groups on the visible side of the Sun, Catania sunspot group 68 and Catania sunspot group 69 (NOAA AR 2694). Solar activity is extremely low, and there were no C-class flares reported for more than ten days. We do not expect significant change in the level of flaring activity. During last 24 hours there were no Earth directed CMEs reported, and the solar protons remained at background level.

Solar wind speed is 410 km/s, and the interplanetary magnetic field magnitude is about 4 nT. The geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours.

Today's estimated international sunspot number (ISN): 011, based on 07 stations.
