We report observations of the Type IIP SN 2019mhm (ATel #12987) in NGC 6753 at 5.5 GHz and 9 GHz using the Australia Telescope Compact Array (ATCA) on 9 August 2019 16:00 UT. No radio emission was detected at the reported location, to a 3-sigma upper limit of 0.12 mJy (5.5 GHz) and 0.08 mJy (9 GHz). Adopting the host galaxy distance as 43.5 Mpc from Bogdan et al. 2017 (ApJ, 850, 98) this implies an upper limit on the 9 GHz luminosity of 1.8E+26 erg/sec/Hz. We would like to extend our thanks to the ATCA staff for enabling the observations. The Australia Telescope Compact Array is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO.
