Bulletin

Solar flaring activity is very low. The only sunspot group presently observed on the visible side of the solar disc, Catania group 44 (NOAA AR region 2775), was not source of the C-class or even B-class flares during last 24 hours. We expect such a low level of flaring activity to persist in the coming hours. During last 24 hours no Earth directed CMEs have been observed in coronagraph data, and proton flux levels remained at background values.

Earth is still inside the slow solar wind with the speed of around 300 km/s. The interplanetary magnetic field magnitude remains to have value of about 5 nT. The geomagnetic conditions are quiet, and we expect them to remain so in the coming hours.

Today's estimated international sunspot number (ISN): 000, based on 19 stations.
