The optically-bright Galactic nova in Musca (CBET #4473, ATel #11183, #11201, #11221) was detected at radio wavelengths using the Australia Telescope Compact Array (ATCA) on 2018 Feb 5.8 UT. It was detected at 5 sigma at 5 GHz (0.10 mJy), while at 9 GHz it was observed to have a flux density of 0.22 +/- 0.02 mJy. The radio spectral energy distribution is therefore consistent with an optically thick, brightening source. More radio observations are planned, and we encourage observations across the electromagnetic spectrum. 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.
