Wang (THU),\n\nreport on behalf of the Zadko Telescope team and GRANDMA collaboration;\n\nWe performed tiled observations of LIGO/Virgo BNS event S190425z with \nthe Zadko telescope, using a clear filter.\n\nThe observation started on 04/25/19 14:56:19 UTC which corresponds \napproximately to 6.65 hours after the GW trigger time. However, due to \nhardware issues, the first images of interest were obtained the next day \n(04/26/19, 14:19:00 UTC)\n\nWe performed the following observations in galaxy targeting mode:\n\n   R.A.      DEC.\n16:57:53 -01:56:51\n16:57:38 -01:48:37\n16:57:07 -01:52:10\n16:04:51 +24:03:15\n16:04:32 +23:55:05\n\nWe have not found any credible counterpart candidate, down to R ~ 16.\n\nThe Zadko team acknowledges support from the OzGrav Centre of Excellence \nof the Australian Research Council.
