The Type Ic Supernova 2011hp (CBET #2899) in the galaxy NGC 4219 has been observed with the ATCA + CABB 2 GHz backend system on 2011 Nov 8.8 at frequencies of 5.5 and 9.0 GHz. No radio emission was detected at the supernova location, with 3-sigma upper limits of 0.24 mJy at 9.0 GHz, and 0.20 mJy at 5.5 GHz. Adopting a host galaxy distance of 23.7 Mpc from NED, this implies an upper limit on the luminosity at 5.5 GHz of 1.3E26 erg/s/Hz. We would like to extend our thanks to the ATCA staff for enabling these observations.
