We present optical , radio and X-ray data that confirm a new supernova remnant ( SNR ) in the Large Magellanic Cloud ( LMC ) discovered using our deep H \alpha imagery .
Optically , the new SNR has a somewhat filamentary morphology and a diameter of 56 \times 64 arcsec ( 13.5 \times 15.5 pc at the 49.9 kpc distance of the LMC ) .
Spectroscopic follow-up of multiple regions show high [ S ii ] /H \alpha emission-line ratios ranging from 0.66 \pm 0.02 to 0.93 \pm 0.01 , all of which are typical of an SNR .
We found radio counterparts for this object using our new Australia Telescope Compact Array ( ATCA ) 6 cm pointed observations as well as a number of available radio surveys at 8 640 MHz , 4 850 MHz , 1 377 MHz and 843 MHz .
With these combined data we provide a spectral index \alpha \approx –0.5 between 843 and 8 640 MHz .
Both spectral line analysis and the magnetic field strength , ranging from 124 - 184 ~ { } \mu G , suggest a dynamical age between \sim 2,200 and \sim 4,700 yrs .
The SNR has a previously catalogued X-ray counterpart listed as HP 483 in the ROSAT Position Sensitive Proportional Counter ( PSPC ) catalogue .
