Abstract
We report Very Large Array (VLA) observations of the ultraluminous supersoft X-ray source in M101, currently undergoing a strong X-ray outburst (ATEL #305, ATEL #306). Data taken on 21 July 2004 show no detections at 4.86 and 8.46 GHz, with nominal flux densities at the Chandra position (ATEL #305) of 0.093 +/- 0.033 mJy/beam and 0.007 +/- 0.025 mJy/beam respectively. The 4.86 GHz data at this position are partially contaminated by a nearby (14 arcseconds away) confusing source, CasHII.
