The radio counterpart of IGR J00291+5934

We report further observations of the proposed radio counterpart to the accreting millisecond X-ray pulsar IGR J00291+5934. Following the report of a possible ~1.1 mJy radio counterpart at 15 GHz on 2004 Dec 4 (ATEL #355), further observations with the Ryle Telescope (12 hr from 2004 Dec 05 13h41m UT) did not detect the source with a 3-sigma upper limit of ~0.6 mJy. A ~10hr observation with the Westerbork Synthesis Radio Telescope (WSRT) (2004-12-06 14:45 UT --- 2004-12-07 00:58 UT) has detected a radio source with a mean flux density of 250 +/- 35 microJy at 5 GHz, with some possible evidence for fading during the run.
