GRB 230217A: ATCA rapid-response radio detection
Abstract
The Australia Telescope Compact Array (ATCA) automatically triggered on the Swift-BAT detection of the short GRB 230217A (Moss et al., GCN 33339) at 5.5 and 9 GHz using the rapid-response mode under program C3204 (PI: Anderson). ATCA was on target observing GRB 230217A at 22:20:19.9 UT, just 27 minutes post-burst (Moss et al., GCN 33339) and observed for 7 hours. At the position of the proposed X-ray (Capalbi et al., GCN 33348, GCN 33365), radio (Schroeder et al., GCN 33358) and optical (D'Avanzo et al., GCN 33374) counterpart, we detected a source at both 5.5 GHz and 9 GHz with flux densities of 170 +/- 30 and 150 +/- 20 microJy/beam, respectively. Further observations have been taken. We thank the ATCA and the CSIRO Space and Astronomy staff for supporting and maintaining the ATCA rapid-response observing mode.
