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-alphaimagery. Optically, the new SNR has a somewhat filamentary morphology and adiameter of 56 x 64 arcsec (13.5 x 15.5 pc at the 49.9 kpc distance of theLMC). Spectroscopic follow-up of multiple regions show high [SII]/H-alphaemission-line ratios ranging from 0.66+/-0.02 to 0.93+/-0.01, all of which aretypical of an SNR. We found radio counterparts for this object using our newAustralia Telescope Compact Array (ATCA) 6cm pointed observations as well as anumber of available radio surveys at 8 640 MHz, 4 850 MHz, 1 377 MHz and 843MHz. With these combined data we provide a spectral index (alpha) = -0.5between 843 and 8640 MHz. Both spectral line analysis and the magnetic fieldstrength, ranging from 124 - 184 mG, suggest a dynamical age between 2,200 and4,700 yrs. The SNR has a previously catalogued X-ray counterpart listed as HP483 in the ROSAT Position Sensitive Proportional Counter (PSPC) catalogue.
