We observed a Type IIn supernova SN 2008X (CBET 1239) in NGC 4141 with the VLA in 8.46 GHz frequency band on 2008 Feb 19.39 UT. We do not detect any radio source at the supernova position (CBET 1239). The peak flux density at the supernova position is 8 +/- 38 uJy. We thank VLA staff for making this observation possible.
