The apparently SN 2009ip-like transient ASASSN-16jt coincident with the Type IIn-pec SN 2016cvk (ATel #9439, #9445; http://wis-tns.weizmann.ac.il/object/2016cvk ) in the galaxy ESO 344-G021 has been observed with the Australia Telescope Compact Array (ATCA) at 5.5 and 9 GHz on 2016 Sep 4.6 UT. No radio emission was detected at the reported location, to a 3-sigma upper limit of 68 microJy/beam (5.5 GHz) and 75 microJy/beam (9.0 GHz). Adopting the host galaxy luminosity distance of 41.3 Mpc from NED, this implies an upper limit on the luminosity at 9 GHz of 1.4E26 erg/s/Hz. For comparison SN 2009ip reached a peak 9 GHz luminosity of 5E25 erg/s/Hz at a comparable age (Margutti et al. 2014, ApJ, 780:21). We would like to extend our thanks to the ATCA staff, particularly Phil Edwards 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.
