TITLE: GCN CIRCULAR NUMBER: 25691 SUBJECT: LIGO/Virgo S190814bv: ATCA monitoring of ASKAP J005547-270433/AT2019osy DATE: 19/09/10 00:30:43 GMT FROM: Dougal Dobie at VAST Dougal Dobie (University of Sydney/CSIRO), Emil Lenc (CSIRO), Ian Brown (UWM),Tara Murphy (University of Sydney), Adam Stewart (University of Sydney), David Kaplan (UWM), Kunal Mooley (Caltech), Gregg Hallinan (Caltech) and the OzGrav, JAGWAR and GROWTH collaborations. We observed ASKAP J005547.4-270433/AT2019osy (GCN 25487) with the Australia Telescope Compact Array (ATCA) on 2019 September 6 from 12:30-19:30 UT. We report flux densities of: 380+/-21 uJy at 5.0 GHz 353+/-17 uJy at 6.0 GHz 299+/-14 uJy at 8.5 GHz 234+/-14 uJy at 9.5 GHz Which are consistent with the measurements obtained with the ATCA on 2019 August 29, 8 days prior (GCN 25487, GCN 25621, GCN 25539). Therefore the previously observed variability is unlikely to be related to S190814bv. Thank you to CSIRO staff for supporting these observations.
