Bulletin

Sun remains to be spotless and accordingly solar flaring activity is very low, without any flares reported in last several days. We do not expect any flaring activity in the coming hours. During last 24 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 increase of the density and fluctuation of the interplanetary magnetic field observed this morning, was followed by the increase of the temperature and solar wind speed. These observations show possible arrival of the solar wind from the positive polarity coronal hole that reached central meridian on January 10. Patchy, negative polarity coronal hole has reached central meridian this morning. The solar wind originating from this coronal hole might be expected at the Earth in the second half of the January 20. Presently geomagnetic conditions are quiet to unsettled and we expect them to stay so in the coming hours.
