Context. The supernova remnants (SNRs) known in the Large Magellanic Cloud (LMC) show a variety of morphological structures in the different wavelength bands. This variety is the product of the conditions in the surrounding medium with which the remnant interacts and the inherent circumstances of the supernova event itself. Aims. This paper performs a multi-frequency study of the LMC SNR J0530-7007 by combining Australia Telescope Compact Array (ATCA), Molonglo Observatory Synthesis Telescope (MOST), Röntgensatellit (ROSAT) and Magellanic Clouds Emission Line Survey (MCELS) observations. Methods. We analysed radio-continuum, X-ray and optical data and present a multi-wavelength morphological study of LMC SNR J0530-7007. Results. We find that this object has a shell-type morphology with a size of 215′′ × 180′′ (52 pc × 44 pc); a radio spectral index (α =-0.85 ± 0.13); with [S II]/Hα > 0.4 in the optical; and the presence of non-thermal radio and X-ray emission. Conclusions. We confirmed this object as a bona-fide shell-type SNR which is probably a result of a Type Ia supernova.
