The Type II Supernova 2009dd (CBET #1764, #1765), in the galaxy NGC 4088, has been the subject of a radio search using the Very Large Array (VLA) at 1.3 cm (22.46 GHz) and 3.5 cm (8.46 GHz) on 2009 April 16.3 (UT). No radio emission was detected at the supernova location, with 3-sigma upper limits of 0.35 mJy at a resolution of 0.38" at 1.3 cm, and of 0.15 mJy at a resolution of 1.1" at 3.5 cm. Further radio observations will be scheduled. We would like to extend our thanks to the VLA scheduling officers and telescope operators for their support of our observing program.
