Rumsey (MRAO)\n\nWe observed the position of GRB 140709A (GCN 16546) at 15 GHz with\nthe Arcminute Microkelvin Imager (AMI-LA) starting on 2014 July 11.93 to\n12.10 UT, corresponding to 2.88 days post-burst. We have detected a\npossible radio counterpart consistent with the UVOT-enhanced XRT position\n(GCN 16548) with a preliminary flux of 0.35 +/- 0.06 mJy. However, this\nsource is blended with the nearby NVSS source 201841+511349 lying\nat an angular distance of 27.5 arcseconds. The angular resolution of AMI\nis ~30 arcseconds. The flux was calculated by first subtracting the contribution\nfrom the NVSS source.\nEarlier AMI observations an 2014 July 9.05 to 9.14 UT and July 10.04 to 10.2,\ncorresponding to <5 minutes and 1 day post-burst, did not detect a radio source\nat the position of the GRB with 3 sigma upper limits of 0.30 and 0.21 mJy, respectively.\nFurther AMI monitoring is planned. We thank the AMI staff for scheduling these observations.",
