The young Type IIP supernova ASASSN-16cc (ATel #8736, #8748) in the galaxy NGC 2101 has been observed with the Australia Telescope Compact Array (ATCA) at 5.5 and 9 GHz on 2016 Feb 29.3 UT and again on 2016 March 12.6 UT. No radio emission was detected at the supernova location, to a 3-sigma upper limit at both frequencies of 0.03 mJy (Feb 29) and 0.06 mJy (12 Mar). Adopting the host galaxy luminosity distance of 17.5 Mpc from NED, this implies an upper limit on the luminosity at 5.5 GHz of 2.2E25 erg/s/Hz. This is comparable to the peak luminosity achieved by other Type IIP events like SN 2004dj and SN 1999em at a similar age, but well below that ultimately reached by SN 2004et (Perez-Torres et al. 2014, http://adsabs.harvard.edu/abs/2015aska.confE..60P ). 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.
