Bulletin

Solar activity is low, without B-class or C-class flares reported during last 24 hours. We expect such a low level of flaring activity to persist in the coming hours. During last 24 hours there were no Earth directed CMEs and the solar protons remained at the background level.

Earth is presently within the slow solar wind with the speed of about 350 km/s and the interplanetary magnetic field magnitude is 4 nT. The solar wind originating from the positive polarity coronal hole, that reached the central meridian on January 10, can be expected to arrive to the Earth starting from this evening. It might induce unsettled geomagnetic conditions. The geomagnetic conditions are presently quiet and we expect them to stay so in the coming hours.

Today's estimated international sunspot number (ISN): 000, based on 17 stations.
