Clean maps of the binary HD 160934 at the three EVN epochs. The lowest contour levels corresponds to 3 times the statistical rms noise (0.04, 0.02, and 0.04 mJy beam-1) with a scale factor between contiguous contours of . The peak flux densities in the images are 0.15, 0.04, 0.12 mJy beam-1, respectively. For image parameters see Table 1. In all the maps we set the origin at the position of the peak of brightness of HD 160934 A. Component c is not detected at epoch 2013.392. Orbital motion of c around A is evident from epochs 2012.830 and 2014.175.
