Abstract

We performed tiled observations of LIGO/Virgo event S190814bv (GCN #25324) with the TAROT-Reunion (Les Makes Observatory, La Reunion Island, France) telescope operating in clear filter. The observations started on 08/14/19 21:41:19 UTC which corresponds approximately to 31 minutes after the GW trigger time. We performed the following tiled observations : +------------+------------+---------+---------+---------+ | TStart | TEnd | RA | DEC | Proba | | [UTC] | [UTC] | [deg] | [deg] | [%] | |------------+------------+---------+---------+---------| | 2019-08-14 | 2019-08-14 | 9.3506 |-28.6364 | 0.4 | | 21:41:19 | 23:12:44 | | | | | 2019-08-14 | 2019-08-14 | 0.0000 |-32.7273 | < 0.1 | | 22:02:49 | 23:25:55 | | | | | 2019-08-14 | 2019-08-16 | 13.500 |-24.5454 | 76.0 | | 22:14:55 | 00:48:18 | | | | | 2019-08-14 | 2019-08-14 | 20.6897 | -8.1818 | < 0.1 | | 22:28:09 | 23:51:15 | | | | | 2019-08-14 | 2019-08-15 |354.8571 |-36.8182 | < 0.1 | | 22:47:06 | 00:09:59 | | | | | 2019-08-14 | 2019-08-14 | 4.6753 |-28.6364 | < 0.1 | | 23:00:04 | 23:04:30 | | | | | 2019-08-15 | 2019-08-15 | 9.0000 |-24.5454 | 6.3 | | 00:15:59 | 00:46:01 | | | | | 2019-08-15 | 2019-08-21 | 24.324 |-32.727 | 7.4 | | 19:54:58 | 01:01:29 | | | | +------------+------------+---------+---------+---------+ TStart and TEnd refer respectively to the time of the first and last exposure for a given tile.

These observations cover about 89% of the cumulative probability of the LALInference skymap with HLV (posted at Aug 15, 2019 09:07:19 UTC) The typical limiting magnitude is 16.0 for a 60.0 s exposure due to bad conditions of observations. No serious transient candidates were found during our low latency analysis.

No sources were found giving an upper limit at 16 mag for a possible optical counterpart. We have also found no source (3 sigma) at locations of desgw-190814j, desgw-190814m, desgw-190814o (GCN #25425), DG19hqpgc, DG19tzyhc, DG19wgmjc, DG19sevhc (GCN #25362), DG19vodmc, DG19gcwjc, DG19rzhoc, DG19tvtnc, DG19sbzkc, DG19hqhjc (GCN #25393), PS19epf, PS19eph (GCN #25356), desgw-190814a (GCN #25336), desgw-190814q (GN #25438).
