TITLE: GCN CIRCULAR NUMBER: 21890 SUBJECT: LIGO/Virgo G297595: NIR Observations following GW170814 DATE: 17/09/15 18:28:20 GMT FROM: Nial Tanvir at U of Leicester S. Rosetti, N. R. Tanvir, A. J. Levan, C. Gonzalez-Fernandez, D. Steeghs, K. Wiersema report on behalf of the VINROUGE collaboration: NIR follow-up observations were carried out using the 4m ESO/VISTA telescope at the Paranal Observatory (Cerro Paranal, Chile) in response to the LIGO/Virgo trigger G297595/GW170814 (GCN  21474). The observations took place between 05:37:37 UT on 14 August 2017 and 09:47:17.6 UT on 16 August 2017. 22 tiles were produced for each filter (Ks, J and Y), each covering a 1.5 square degree area. Analysis is ongoing. The targeted areas are listed as follows: UT(DAY MIN:SEC) RA (J2000) Dec (J2000) Filter —————————————————————————— 20170814 347:41.0 02:38:41.2 -44:24:38.8 J 20170814 337:37.0 02:38:41.2 -44:24:39.4 Ks 20170814 357:17.0 02:38:41.2 -44:24:38.8 Y 20170814 397:03.6 02:35:19.1 -45:51:33.8 J 20170814 380:06.0 02:35:19.0 -45:51:34.3 Ks 20170814 409:21.0 02:35:19.1 -45:51:33.8 Y 20170814 436:38.6 02:34:37.4 -47:19:04.0 J 20170814 426:25.0 02:34:37.4 -47:19:04.6 Ks 20170814 446:18.6 02:34:37.4 -47:19:04.0 Y 20170814 468:36.0 02:47:25.1 -42:57:16.9 J 20170814 458:22.6 02:47:25.1 -42:57:17.5 Ks 20170814 480:14.0 02:47:25.1 -42:57:16.9 Y 20170814 511:52.0 02:34:48.7 -48:46:33.8 J 20170814 490:19.6 02:34:48.6 -48:46:34.4 Ks 20170814 523:49.0 02:34:48.7 -48:46:33.8 Y 20170814 548:35.0 02:51:26.4 -41:29:06.0 J 20170814 536:30.0 02:51:26.4 -41:29:06.5 Ks 20170814 560:49.0 02:51:26.4 -41:29:06.0 Y 20170814 583:24.6 02:39:15.5 -47:19:02.9 J 20170814 570:45.6 02:39:15.4 -47:19:03.5 Ks 20170814 593:07.0 02:39:15.5 -47:19:02.9 Y —————————————————————————— 20170815 337:34.6 02:40:38.7 -45:51:37.0 J 20170815 327:33.6 02:40:38.6 -45:51:37.6 Ks 20170815 347:10.0 02:40:38.7 -45:51:37.0 Y 20170815 369:18.0 02:44:30.7 -45:51:37.7 J 20170815 359:08.6 02:44:30.6 -45:51:38.3 Ks 20170815 381:10.0 02:44:30.7 -45:51:37.7 Y 20170815 405:29.0 02:44:11.3 -44:24:41.7 J 20170815 391:23.6 02:44:11.2 -44:24:42.3 Ks 20170815 416:17.0 02:44:11.3 -44:24:41.7 Y 20170815 440:25.0 02:49:23.3 -44:24:41.7 J 20170815 426:08.6 02:49:23.2 -44:24:42.3 Ks 20170815 450:37.0 02:49:23.3 -44:24:41.7 Y 20170815 474:00.0 02:52:28.9 -42:57:09.0 J 20170815 463:44.0 02:52:28.8 -42:57:09.5 Ks 20170815 486:23.6 02:52:28.9 -42:57:09.0 Y 20170815 509:14.0 02:54:20.3 -41:29:07.1 J 20170815 496:34.6 02:54:20.3 -41:29:07.6 Ks 20170815 518:55.6 02:54:20.3 -41:29:07.1 Y 20170815 542:40.6 02:50:08.7 -45:51:32.7 J 20170815 531:52.6 02:50:08.6 -45:51:33.3 Ks 20170815 553:59.0 02:50:08.7 -45:51:32.7 Y 20170815 575:29.0 02:43:33.1 -47:19:06.8 J 20170815 564:29.0 02:43:33.0 -47:19:07.5 Ks 20170815 585:24.6 02:43:33.1 -47:19:06.8 Y —————————————————————————— 20170816 367:55.0 03:05:18.2 -44:24:41.0 J 20170816 358:02.0 03:05:18.2 -44:24:41.5 Ks 20170816 377:26.0 03:05:18.2 -44:24:41.0 Y 20170816 399:22.6 03:10:48.2 -44:24:41.0 J 20170816 389:15.0 03:10:48.2 -44:24:41.5 Ks 20170816 410:03.0 03:10:48.2 -44:24:41.0 Y 20170816 431:04.6 02:59:47.3 -44:24:41.7 J 20170816 421:00.0 02:59:47.2 -44:24:42.3 Ks 20170816 440:36.0 02:59:47.3 -44:24:41.7 Y 20170816 462:34.6 03:07:06.8 -42:57:13.0 J 20170816 452:29.0 03:07:06.7 -42:57:13.5 Ks 20170816 474:18.6 03:07:06.8 -42:57:13.0 Y 20170816 495:41.6 03:01:24.9 -45:51:34.8 J 20170816 484:19.6 03:01:24.9 -45:51:35.4 Ks 20170816 505:18.0 03:01:24.9 -45:51:34.8 Y 20170816 530:22.6 03:06:43.4 -45:51:35.9 J 20170816 520:16.6 03:06:43.4 -45:51:36.5 Ks 20170816 539:55.6 03:06:43.4 -45:51:35.9 Y 20170816 568:38.6 03:15:04.6 -44:24:41.7 J 20170816 558:28.0 03:15:04.5 -44:24:42.3 Ks 20170816 579:28.0 03:15:04.6 -44:24:41.7 Y
