1.284-GHz MeerKAT image of the sky region around J1109. The image was obtained from a stack of the data acquired on 2019 June 14 and 15 and its size is 2.5′×2.5′ (north is up and east to the left). The sky region is color-coded according to the values of the brightness at each position, as indicated by the color bar on the top. The rms noise level in this image is 4.2 μJy beam⁻¹. Contour levels are drawn at intervals of (2^n/2)×30 μJy beam⁻¹, where n = 0, 1. The position of the optical counterpart of J1109 (see Sect. 2.1.1) is marked using a grey cross at the centre of the image. The grey ellipse in the frame in the bottom-left corner represents the shape and size of the synthesised beam, where the major axis is 13.2″, the minor axis is 7.0″, and the major axis is located at a position angle of 43.0° measured from north towards east.
