Cambridge) reports on behalf \nof the AMI collaboration:\n\nThe AMI Large Array (the rebuilt Ryle Telescope) was used to observe \nthe field of GRB 090618 (Schady et al, GCN9512) on 2009 June 19 \nfrom 02h45m to 05h45m UT (18.25 to 21.25h after the burst) \nusing the position from Cenko et al (GCN9213). \nThe observing band was 14.6 to 17.5 GHz and the rms noise 85 microJy. \nThe angular resolution is approx. 50\" x 20\".\n\nWe make a clear detection of a source at the position of the GRB\nwith a flux density 550 microJy. A split of the data suggests that \nthe flux density increased from 425 to 640 microJy between the\nfirst and second halves of the observation, but this is barely \nstatistically significant. \n\nThere is no radio source visible at that position in the NVSS (1.4GHz).\n\nThis report may be quoted in publications.",
