We report radio observations with the Jansky Very Large Array of the Type
Ic supernova SN2013bv discovered by Zhang et al.(CBET #3499) on April
9.51 UT and spectroscopically classified as broad-lined supernova similar to
SN1998bw by Silverman et al. (CBET #3499).
On 2013 April 27.0 UT, we triggered VLA observations at the position
of SN2013bv 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 7 microJy. At a distance of roughly 400 Mpc, this
implies a limit on the spectral luminosity of ~1e27 erg/s/Hz.
The observed radio luminosity of SN2013bv is therefore about a
factor of 30 lower than that of SN1998bw at a comparable epoch
(Kulkarni et al. Nature 1998).
