The nearby Type IIn Supernova SMTJ07350518-6907531 (ATel #7711) has been observed with the Australia Telescope Compact Array (ATCA) + CABB 2 GHz backend system on 2015 Jun 29.1 UT at frequencies of 9.0 and 5.5 GHz. We detected a radio source at a position consistent with that measured optically, and fluxes of 0.07+/-0.02 mJy and 0.10+/-0.03 mJy at 9.0 and 5.5 GHz, respectively. Although the host galaxy and distance are still somewhat indeterminate, this is consistent with the slow rise to peak luminosity characteristic of other Type IIn supernovae. Monitoring at these and other frequencies is continuing. We would like to extend our thanks to the ATCA staff for enabling these observations. The Australia Telescope Compact Array is part of the Australia Telescope National Facility which is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO.
