Kulkarni (Caltech)\nreport on behalf of a larger collaboration:\n\n\"We used the Very Large Array to observe the field of view toward the\nhigh redshift GRB 090423 (GCN 9198) at a frequency of 8.46 GHz on 2009\nApr. 25.00 UT. We do not detect any radio emission either within the\nSwift-XRT error circle (GCN 9205) or at the UKIRT K-band position (GCN\n9202). The 3-sigma upper limit on the radio flux density of GRB\nafterglow is 135 uJy (map rms 45 uJy).\n\nThe National Radio Astronomy Observatory is a facility of the National\nScience Foundation operated under cooperative agreement by Associated\nUniversities, Inc.\"",
