The Type IIP Supernova 2012A (CBET #2974,2975) in the galaxy NGC 3239 has been observed with the Karl G. Jansky Very Large Array on 2012 Jan 9.4 at frequencies of 29 and 37 GHz. No radio emission was detected at the supernova location, with 3-sigma upper limits of 0.18 mJy at 29 GHz, and 0.26 mJy at 37 GHz, with a combined limit of 0.15 mJy centered at 33GHz. Adopting a host galaxy distance of 8.1 Mpc from NED, this implies an upper limit on the luminosity at 33 GHz of 1.1E25 erg/s/Hz.
