TITLE: GCN CIRCULAR NUMBER: 31665 SUBJECT: ZTF22aaajecp/AT2022cmc: ATCA detection DATE: 22/03/02 22:55:50 GMT FROM: Dougal Dobie at VAST D. Dobie (Swinburne/OzGrav), A. O'Brien (UW Milwaukee), A. Zic (Macquarie U./CSIRO), D.L. Kaplan (UW Milwaukee), D.A. Perley (LJMU), A.Y.Q Ho (UC Berkeley) We carried out observations of ZTF22aaajecp/AT2022cmc (Andreoni et al. GCN 31590) with the Australia Telescope Compact Array (ATCA) on 2022-02-26 (~15.25 days post-discovery). The array was in the EW367 array configuration and we excluded CA06 from our processing to obtain more uniform u-v coverage. We used 3C286 for gain, bandpass and flux scale calibration to ensure consistency with observations from Northern radio facilities. We detect a compact radio source at the location of the transient and measure a flux density of ~1.6 mJy at 33.5 GHz. Further observations are planned. Thank you to CSIRO staff for supporting these observations.
