The Type II SN 2016gkg (ATel #9521, #9528, #9544) in the galaxy NGC 613 has been observed within 3 days of explosion using the Australia Telescope Compact Array (ATCA) at 19 GHz on 2016 Sep 23.5 UT. No radio emission was detected at the reported location, to a 3-sigma upper limit of 0.15 milliJy/beam. Adopting the same host galaxy distance as Kilpatrick et al. (ATel #9536) of 26.4 Mpc, this implies an upper limit on the luminosity at 19 GHz of 1.25E26 erg/s/Hz. We would like to extend our thanks to the ATCA staff for enabling these observations. The Australia Telescope Compact Array is funded by the Commonwealth of Australia for operation as a National Facility managed by CSIRO.
