We report observations of 2 recent supernovae and 1 candidate supernova at 5.5 GHz and 9.0 GHz using the Australia Telescope Compact Array on 2020 April 13.5-13.7 UT. The targets included the Type II/IIb SN 2020fqv (ATel #13605, #13607; TNS AstroNote 2020-80) in NGC 4568; the Type II SN 2020fsb (TNS AstroNote 2020-76) in the galaxy ESO 515-G004; and the candidate supernova AT 2020hat (TNS AstroNote 2020-81) in NGC 5068. No radio counterparts were detected at the expected locations of any of the sources, to 3-sigma limits of ~0.06 mJy (5.5 GHz) and ~0.04 mJy (9.0 GHz). 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.
