GRB 200219A: ATCA 5/9 GHz radio observations

Abstract

We used the Australia Telescope Compact Array (ATCA) to perform a radio observation of the short GRB 200219A. The scheduled observations began on 2020 Feb 22.8 UT for 7.5 hours (3.5 days post-burst; Fermi GBM Team GCN 27123, A. Y. Lien et al., GCN 27125). No radio source was detected at the XRT position (J.P. Osborne et al., GCN 27138), with preliminary 3 sigma upper-limits of 53 microJy and 57 microJy at 5.5 and 9 GHz, respectivel
