The solar activity was very low. Regions NOAA 2284 and 2285 were decaying further, while NOAA 2282 was stable. Flaring activity is expected to remain low, with some chance for C-flares during the next two days. No CMEs Earth directed CMEs were observed. The interplanetary magnetic field was enhanced but with a decreasing magnitude from 14 to 5 nT. The Bz component mostly was negative. The disturbance starting at 9:40 UT on 16th of February possibly is related to a equatorial CH that passed the central meridian on the 11th of February. The solar wind speed steadily increased from about 400 to 470 km/s. Geomagnetic conditions were unsettled, with a several time slots of active conditions (K=4) at the global and local level (after 18 UT on the 17th and at 3 and 4 UT on the 18th of February at the local level at Dourbes). Geomagnetic conditions are expected to return to quiet to unsettled levels for the next 48 hours.
