The young Type II SN 2018lab/DLT18ar (ATel #12339, #12342) in the galaxy IC 2163 has been observed with the Australia Telescope Compact Array (ATCA) at 5.5 and 9.0 GHz on 2019 Jan 05.6 UT. No radio emission was detected at the reported location, to a 3-sigma upper limit of 0.10 milliJy/beam (5.5 GHz) and 0.05 milliJy/beam (9.0 GHz). Adopting the host galaxy distance from Jencson et al. (arXiv:1901.00871) this implies an upper limit on the 9 GHz luminosity of 7.5E25 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.
