Naturally-weighted 7.25 GHz image of the sky region around J1109, extracted from our 4.8 h long ATCA observation on 2018 June 20. A logarithmic scale was adopted for better visualization. The white circle is centred on the optical position of J1109, with an enlarged radius of 10 arcsec for imaging purposes. The green ellipse denotes the error region for the position of the Fermi/LAT gamma-ray source.
