J. van der Horst (GWU), S. D. Ryder (Macquarie), A. Rowlinson (UvA, ASTRON),\r\nR. A. M. J. Wijers (UvA)\r\n\r\nThe Australia Telescope Compact Array (ATCA) automatically triggered on\r\nthe Swift-BAT detection of the short GRB 230217A (Moss et al., GCN 33339)\r\nat 5.5 and 9 GHz using the rapid-response mode under program C3204\r\n(PI: Anderson). ATCA was on target observing GRB 230217A at 22:20:19.9 UT,\r\njust 27 minutes post-burst (Moss et al., GCN 33339) and observed for 7 hours.\r\nAt the position of the proposed X-ray (Capalbi et al., GCN 33348, GCN 33365),\r\nradio (Schroeder et al., GCN 33358) and optical (D���Avanzo et al., GCN 33374)\r\ncounterpart, we detected a source at both 5.5 GHz and 9 GHz with flux densities\r\nof 170 +/- 30 and 150 +/- 20 microJy/beam, respectively.\r\nFurther observations have been taken.\r\n\r\nWe thank the ATCA and the CSIRO Space and Astronomy staff for supporting\r\nand maintaining the ATCA rapid-response observing mode.",
