The young core-collapse supernova SN 2022acko (=DLT22v/ATLAS22bnms/ZTF22abyivoq; TNS Astronomical Transient Report No. 166420) in NGC 1300, classified as a type IIP event, has been observed with the Australia Telescope Compact Array (ATCA) at 5.5 and 9.0 GHz on 08 Dec 2022 10:20-13:05 UT. No radio emission was detected to 3-sigma upper limits on the flux density of 0.045 mJy and 0.035 mJy at 5.5 GHz and 9.0 GHz, respectively. Adopting a host galaxy distance of 19 Mpc from Lee et al. 2022 (arXiv:2212.02667) this implies an upper limit on the 5.5 GHz luminosity within 3 days of explosion of 1.9E+25 erg/sec/Hz. We would like to extend our thanks to the ATCA staff for enabling these observations. The ATCA 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. We acknowledge the Gomeroi people as the traditional owners of the Observatory site.
