We observed the field of the transient AT2020xnd (ATel #14105) from 06:30-12:30 UTC on 2020-11-07 with the Australia Telescope Compact Array. Observations were carried out in a hybrid correlator mode, with one band centered on 33 GHz with 2048x1 MHz channels and a second band centered on 35 GHz with 32x64 MHz channels. A single zoom band with 2048x32 kHz channels was centered at 35 GHz to allow for delay calibration of the continuum band.
A source is clearly detected at the location of AT2020xnd in each band, and we report a flux density of 310 +/- 20 uJy at 34 GHz after combining both bands.
Further observations are planned. Thank you to CSIRO staff for supporting these observations.
