Kulkarni (Caltech) report on behalf of a larger collaboration: "Beginning at 7:39 UT on 1999 February 18 we observed a region covering the WFC error circle of GRB 990217 (GCN #258, IAU Circ 7710) with the Australia Telescope Compact Array (ATCA) at 4.8 GHz and 8.6 GHz. The total observing time was 3.6 hours. Within a 3 arcmin radius around the GRB position no radio sources were detected down to 0.28 mJy (5 sigma) at either frequency. Deeper ATCA observations are planned for this week." This message is citeable.
