Solar activity is very low, without C-class or even B-class flares reported for more than a week. We expect such a low activity to persist in the coming days. There were no Earth directed CMEs observed during last 24 hours, and the solar protons are at background level. The in situ observations (from DSCOVR satellite) indicate arrival of the interplanetary shock wave at 05:55 UT this morning. The sudden increase of the solar wind speed (from about 290 to 350 km/s) was observed simultaneously with the increase of the density, temperature and the interplanetary magnetic field magnitude (from about 6 nT to 15 nT). The shock in the solar wind is probably related with the expected arrival of the fast solar wind associated with the low latitude extension of the northern polar coronal hole which reached central meridian late evening of January 04. The solar wind speed is slowly increasing and it presently amounts 360 km/s and the interplanetary magnetic field magnitude is 20 nT. The Bz component turned negative about two hours ago and it presently amounts about -13 nT. If the negative value of the Bz component persists for a longer time interval we can expect disturbed geomagnetic conditions (up to Kp=4). The geomagnetic conditions are presently quiet and we expect unsettled to active geomagnetic conditions in the coming hours.
