V4641 Sgr field as observed by the MeerKAT interferometer in the L band (central frequency of 1.217 GHz), with an angular resolution of 8″. The background noise level is 4 μJy beam⁻¹, while the noise level in the region surrounding the bow-tie is on the order of 10 μJy beam⁻¹. The position of V4641 Sgr is marked by a black dot inside a white circle. The inset shows the central region of the field, with the bow-tie outlined in white. The white arrow indicates the proper motion of V4641 Sgr with respect to nearby stars, in the north-northeastern (NNE) direction (position angle of 15° E of N; see Sect. 3.2).
