We observed the Type Ia supernova 2007on (CBET #1121) on 2007 Dec 7.26 UT with the Very Large Array at observing frequencies of 1.43 and 8.46 GHz. No radio emission is detected at the optical position of the SN. We report rms flux density values for the field of 178 (1.43 GHz) and 19 (8.46 GHz) microJy. We thank the NRAO scheduling committee for approving these Rapid Response observations.
