Bulletin

There were no C-class and even no B-class flares reported during last 24 hours. We do not expect any solar flaring activity in the coming hours. Coronagraph images do not show signatures of the Earth directed CME, and the solar protons remained at the background level.

Solar wind speed is presently about 320 km/s and the interplanetary magnetic field magnitude is about 5 nT. The arrival of the fast solar wind associated with the coronal hole which reached central meridian in the morning of January 09 is possible in the coming hours. The geomagnetic conditions are presently quiet to unsettled and we can expect them to stay so, with the possibility of isolated intervals of active geomagnetic conditions due to the influence of expected arrival of the fast solar wind.

Today's estimated international sunspot number (ISN): 000, based on 05 stations.
