We report radio observations with the Jansky Very Large Array of Type Ic supernova CSS130415:114802+543439 discovered by Catalina Sky Survey on April 15 UT (Drake et al.; ATEL #4984) and classified as a type-Ic hypernova similar to SN1998bw by Tomasella et al (ATEL #4989). On 2013 April 19.12 UT, we triggered VLA observations at the position of CSS130415:114802+543439 at 4.8 & 7.1 GHz. No radio emission is detected in either of the frequency bands at the position of the supernova down to 3-sigma RMS level of 10 microJy. The observed radio luminosity if this SN is therefore a factor of > 10 lower than that of SN1998bw at a comparable epoch (Kulkarni et al. Nature 1998). We thank the NRAO staff carrying out this ToO observation.
