There were no C-class and even no B-class flares reported during last 24 hours. The only active region presently observed on the visible side of the solar disc is Catania sunspot group 63 (NOAA AR 2687) which has beta configuration of its photospheric magnetic field and might be source of the B-class and isolated C-class flares (probability of only about 7%) in the coming hours. No Earth directed CMEs were observed in the last 24 hours, and the solar protons remained at background level. The solar wind speed is presently about 400 km/s and the interplanetary magnetic field magnitude is about 8 nT. Due to longer intervals of the negative value of the Bz component, unsettled to active geomagnetic conditions were reported in the late evening of November 14 (local station at Dourbes reported interval with K=4 and NOAA reported interval of Kp=3). The fast flow associated with the low latitude extension of the northern polar coronal hole (reached central meridian in the early morning of November 11) is expected to arrive at the Earth today. The arrival of the fast solar wind migh induce disturbed geomagnetic conditions (up to Kp=4). The geomagnetic conditions are presently quiet to unsettled, and we expect unsettled to active conditions later today or early morning tomorrow.
