I observed the Type Ibc SN 2007uy (IAUC 8908 ) with the Very Large Array beginning on 2008 Jan 6.18 UT. I detect a radio transient at RA=09:09:35.30 Dec=+33:07:09.1 with an uncertainty of 0.1 arcsec in each coordinate which is coincident with the optical position. At 8.46 GHz, the measured flux density of the source is 290 +- 30 microJy. Follow-up observations with the Very Large Array are ongoing. I further note that a simultaneous Swift/XRT observation of the SN reveals a marginally detected X-ray source near the radio SN position. Follow-up observations with Swift are planned and will determine if the X-ray emission can be attributed to the SN. I thank the VLA and Swift scheduling committees for making these ToO observations possible.
