Abstract

We performed tiled observations of the LIGO/Virgo event S190828j with the TAROT-Chili (TCH), TAROT-Calern (TCA) and TAROT-Reunion (TRE) telescopes operating in the visible located respectively at La Silla ESO observatory (LaS/ESO), the Calern site at the Cote d'Azur Observatory and Les Makes astronomical observatory. The observation started for TCH on 08/28/19 07:05:39 UTC which corresponds approximately to 32 minutes after the GW trigger time. We performed the following tiled observations : +-------+------------+------------+---------+---------+---------+ | Tele | TStart | TEnd | RA | DEC | Proba | | scope | [UTC] | [UTC] | [deg] | [deg] | [%] | |-------+------------+------------+---------+---------+---------| | TCH | 2019-08-28 | 2019-08-30 | 312.95 | 12.768 | 0.1 | | | 07:05:39 | 03:48:14 | | | | | TCH | 2019-08-28 | 2019-08-30 | 309.933 | 9.05 | 0.1 | | | 07:34:47 | 03:55:02 | | | | | TCH | 2019-08-29 | 2019-08-30 | 314.525 | 27.707 | 0.1 | | | 00:24:53 | 01:31:01 | | | | | TCH | 2019-08-29 | 2019-08-30 | 319.388 | 21.777 |
