Optical i‐band image of TXS 0004+364. The optical source (circled) has multiple components and extends beyond the radio source, which is <0﹩\farcs﹩1 in size and therefore smaller than 1 pixel. The scale bar is 5^{﹩\arcsec﹩} long. The image is a 3660 s exposure using the COSMIC camera on the Palomar 5 m telescope. The conditions were near‐photometric, and the seeing was ~1﹩\farcs﹩6.
