We observed the optically-bright Galactic nova in Musca (CBET #4473, ATel #11183, #11201) at radio wavelengths with the Australia Telescope Compact Array (ATCA) on 2018 Jan 18.8 UT. No radio emission was detected at the nova's location, yielding 3-sigma upper limits of 60 microJy/bm at 5.5 GHz, and 40 microJy/bm at 9 GHz. We are planning future radio monitoring observations of this nova, and encourage all multi-wavelength observations. 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.
