Archival VLA image of V407 Cyg at 8.4 GHz on 1993 May 18. White contours start at 0.10 mJy beam⁻¹ (about 3× the rms noise level of 42 μJy beam⁻¹) and increase by steps of . The beam size is 2.6″ × 1.0″ in p.a. −82°; the peak brightness is 1.08 mJy beam⁻¹. The inset shows the proper motion determined from the Gaia data between 1993.5 and 2010.3 (maroon arrow) and between 2010.3 and 2015.5 (teal arrow); the (almost circular) ellipses show the uncertainty on the position at the two epochs in corresponding colours, magnified by a factor 5× for readability. The black contours represent 1.6 GHz emission as observed with the EVN on day 44 (same as in Fig. 1).
