We have observed the position of AT2018cow (ATel #11727) with the Australia Telescope Compact Array (ATCA) on 2018-07-03 between 09:00-13:45 UT at central frequencies of 5.5 GHz and 9 GHz with a bandwidth of 2 GHz in each band. We report preliminary flux densities of ~0.4 mJy at 5.5 GHz and ~1.0 mJy at 9 GHz.
We have also observed AT2018cow on 2018-07-05 from 13:30-15:30 UT at a central frequency of 34 GHz with a bandwidth of 4 GHz. We report a preliminary flux density of ~10 mJy.
Analysis is ongoing and subsequent epochs are planned.
Thank you to CSIRO staff for supporting these observations.
