We report radio observations with the Very Large Array (VLA) of supernova SN 2014C (PSN J22370560+3424319; CBET 3777) discovered by Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory on 5th Jan 2014 (ATel #5721) and identified by Asiago as of type-Ib (ATEL #5742).
We observed the position of SN 2014C with the VLA at a mid-time of 2014 Jan 11.1 UT utilizing two, ~1 GHz sidebands centered at 5 & 7 GHz. We detect a radio source with a flux density of 0.8 +/- 0.04 mJy in the upper sideband (7 GHz) with a position consistent with the supernova (ATel #5721). At the distance of the host galaxy, NGC 7331, this corresponds to a spectral luminosity of 10^{26} erg/s/Hz. A coincident radio source was also detected in the lower sideband. Followup observations are ongoing.
