We report radio observations with the Very Large Array (VLA) of supernova of type Ib, CSS141028:J08181390+0445527 (ATel #6657), discovered by Catalina Real-Time Transient Survey.

We observed the position of the supernova with VLA at a mid-time of 2014 Nov 07.5 UT utilizing two, ~1 GHz sidebands centered at 5 & 7 GHz. We detect a faint and unresolved radio emission consistent with the optical location of the supernova. The measured flux density is about 0.13 +/- 0.01 mJy in the lower sideband (5 GHz). At the redshift of 0.009 (luminosity distance of 39 Mpc), this corresponds to a spectral luminosity of 2.4 x 10^{26} erg/s/Hz.

Followup radio observations are ongoing. Multiband and spectroscopic coverage is encouraged.

We thank the NRAO staff for carrying out this observation.
