Caption: Figure 1.

Natural-weighted images of VLBA observations of AT2018cqh at three frequencies. In each image, the bottom right ellipse is the shape of the restoring beam, with sizes of 14.51 × 5.29 mas for the L band, 3.20 × 1.30 mas for the C band, and 1.99 × 0.81 mas for the X band, respectively. The contour levels are 2.5σ × (−1, 1, 2, 4, 8) for the L band and 2.5σ × (−1, 1, 2, 4, 8, 16, 32, and 64) for the C band and X band.
