The nearby Type IIb supernova SN 2016bas (ATel #8814) in ESO 163-G011 has been observed with the Australia Telescope Compact Array (ATCA) on 2016 March 17.4 UT. We detected a radio source at a position consistent with that measured optically, and fluxes of 0.56+/-0.03 mJy and 0.21+/-0.02 mJy at 9.0 and 5.5 GHz, respectively. Although the date of explosion of SN 2016bas is not well-constrained, comparison with other Type IIb events such as SN 2001ig (Ryder et al. 2004, MNRAS, 349, 1093) suggests the source has yet to peak at these frequencies. Monitoring at these and other frequencies is continuing, and further multi-wavelength follow-up is encouraged. We would like to extend our thanks to the ATCA staff for enabling these observations. The Australia Telescope Compact Array 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.
