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, respectively.

We thank the ATCA and CSIRO Astronomy and Space Science (CASS) staff for
scheduling these observations.
