Solar activity was low with X-ray flux remaining below C level and only some small B-level flaring from NOAA region 2610 (Catania group 58) with a maximum amplitude of B4.2 at 16:58UT. Evolution of NOAA region 2610 was marked by additional bipolar flux emergence just to the North-East of the existing sunspot group, with the new group growing in size and the pre-existing group in decay. X-ray flux is expected to remain below C level with only a slight C-class flare probability from NOAA region 2610. A filament lifted off from near disk centre in the North-Eastern quadrant around 14:00UT. However, corresponding coronagraph data do not show any significant Earth directed CME. Proton flux values were at background values and are expected to remain so.

Solar wind speed decayed from around 550 km/s to around 400 km/s at the end of the period. Total magnetic field was in the 3-5nT range with a variable North-South component and the phi angle in the negative sector. Solar wind conditions are expected to continue at nominal levels. A slight increase is possible from 2016-11-18 onwards under the influence of the positive polarity equatorial coronal hole. Geomagnetic conditions evolved from quiet to unsettled to quiet later in the period (both local K Dourbes and NOAA Kp evolving from 1-3 to 0-1). Geomagnetic conditions are expected to continue at quiet levels with unsettled periods becoming more likely later associated with a sector boundary crossing and possible minor influence of coronal hole high speed stream.
