Thierry (Auragne Observatory), \nE.J. Howell (OzGrav-UWA), A. Verveer (ASA), J. Kennewell (UWA, ASA)\n\nreport:\n\nWe observed GRB 191019A (Simpson et al., GCN 26031) with the Zadko \nTelescope (Coward et al. 2017), starting at 2019 October the 19th at\n15:20:23 UT (7 minutes 50 seconds after the trigger) under fair conditions.\n\nThe object reported by Reva et al. (GCN 26036) is clearly visible in our \nimages. However, we measure an R magnitude of 18.92 at the time reported \nby the GCN. Observations stopped one hour twenty three minutes after the \nburst, and during that time we do not see any variation on the light \ncurve, similar to other teams (Perley et al., GCN 26039; Fynbo et al., \nGCN 26041; and Zhu et al., GCN 26059). At that position, the USNO \ncatalog reports a source of magnitude R = 19.0, consistent with our \nfindings. We conclude that this object is not the afterglow of GRB \n191019A, but the host galaxy, as reported by Perley et al. (GCN 26062).\n\n\nThe Zadko Telescope has been under refurbishment during the last year, \nand is still in recommissioning mode.
