We carried out further ATCA observations of AT2020xnd/ZTFacigmel (ATel #14105) between 04:30 and 08:30 UTC on 19/11/2020 with the Australia Telescope Compact Array (ATCA). The data were recorded at 17 and 19 GHz with the array in the H168 configuration.

Combining the data in the two bands we detect AT2020xnd at 240 uJy +/- 20 uJy at 18 GHz when imaging with natural weighting and not including antenna 6. This is a factor two increase in flux density compared to our previous observation at the same frequency on 29/10/2020 (ATel #14148).

We thank Jamie Stevens and the ATCA staff for rapidly scheduling and carrying out these observations.
