Kulkarni (Caltech) report:\n\n\"We obtained a 8.2 hour integration with the Australia Telescope\nCompact Array (ATCA) on February 12.31 UT. In addition, shorter\nintegrations were obtained at 8.46 GHz with the Very Large Array on\nFebruary 10.99, Feb 14.90, Feb 15.03 UT. Both the ATCA and VLA imaged\na field that fully covers the 50-arcsecond error circle of the fading\nNFI X-ray source, as reported by Costa et al. (GCN 553). There are no\nradio sources in the NFI above a 4-sigma level on any of the four\ndays. The rms noise levels are 65 microJy (Feb. 10.99), 55 microJy\n(Feb. 12.31), 35 microJy (Feb. 14.90), and 38 microJy (Feb. 15.03).\nAdding together the data taken on February 14 and 15, we obtain an\nupper limit of 55 microJy (2-sigma) for the flux density of any radio\nafterglow at the position of the Chandra X-ray source (Garcia, Garmire\namd Piro GCN 548).\"\n\nThis message may be cited.",
