TAROT-Reunion (TRE)\ntelescopes operating in the visible located respectively at\nLa Silla ESO observatory (LaS/ESO), the Calern site at\nthe Cote d'Azur observatory and at La Reunion Island, France.\n\nThe observation started for TCA at 09/10/19 02:26:06 UTC which\ncorresponds approximately to 60 minutes after the GW trigger time,\nfor TCH at 09/10/19 04:54:23 UTC which corresponds approximately to\n208 minutes after the GW trigger time, and for TRE at 09/10/19\n19:42:20 UTC which corresponds approximately to 1096 minutes\nafter the GW trigger time.\n\nWe performed the following
