Solar activity was very quiet in the past 24 hours without C-class flares reported. There is only one NOAA active region (AR) 2619 observed on visible side of the solar disk with simple magnetic configuration. No Earth directed CMEs were observed in the past 24 hours. The northern polar coronal hole, which expanded to low latitudes, may disturb the geospace environment from today (19-Dec-2016). Solar proton flux intensity is expected to lie within the background levels. Solar activity is expected to be low with some probability for C-class flares. Variations of the solar wind parameters were low. Total Interplanetary Magnetic field (IMF) strength varied between 7 and 4 nT, while Bz varied between -4.4 and 5.5 nT. The solar wind speed decreased from 450 km/s till 380 km/s. Geomagnetic conditions were quiet (K Dourbes between 0 and 2; NOAA Kp between 1 and 2). The geomagnetic conditions are presently quiet to unsettled. We expect active conditions later today and tomorrow due to expected arrival of the fast solar wind associated with the low latitude extend of the northern polar coronal hole.
