An observation of IGR J00291+5934 (ATEL #352) with 5 antennas of the Ryle Telescope, Cambridge, UK at 15 GHz resulted in a probable detection at 1.1 mJy. The observation was for 5 hours from 2004 Dec 04 17h10m, and was centred on the original position from the INTEGRAL satellite. The detection was the strongest signal in the field which was mapped (6 arcmin FWHM) was 104 arcsec from the pointing centre and was 12 arcsec from the optical position (ATEL #353); the resolution of the telescope in this mode is about 25 arcsec. The signal/noise ratio is about 3.5. A further observation is in progress.
