Bülletään

The only active region on the visible side of the Sun is NOAA AR 2694 which presently has beta configuration of its photospheric magnetic field. There were no C-class or even B-class flares reported during last 24 hours and we expect such a low flaring activity to persist in the coming hours. There were no Earth directed CMEs observed during last 24 hours, and the solar protons are at background level. The Earth is presently inside the fast solar wind (about 520 km/s) associated with the low latitude extension of the northern polar coronal hole which reached central meridian late on the January 04. The interplanetary magnetic field magnitude has decreased and it now amounts about 5 nT. The equatorial coronal hole (between N05 and N30) has reached central meridian this morning. The associated fast solar wind might be expected at the Earth late on January 12. Due to the longer interval of the negative value of the Bz component of the interplanetary magnetic field and the fast solar wind, disturbed geomagnetic conditions were reported yesterday afternoon (Dourbes reported K=4) and this morning (NOAA reported Kp=4). The geomagnetic conditions are presently quiet and we expect quiet to unsettled geomagnetic conditions in the coming hours.
