Klotz (IRAP), C.Lachaud (APC),\non behalf of the SVOM Gravitational Astronomy group report:\n\nWe observed about 1200 square degree (3 sky regions) of the skymap\nof the advanced LIGO trigger G288732, with SVOM/Mini-GWAC, at Xinglong\nObservatory of NAOC equipped with U9000 camera (FOV~400 square\ndegree/camera).\nSVOM/Mini-GWAC comprises 12 wide field angle cameras (aperture=7cm),\nworking with unfiltered band. The observations are operated in time-series\nmode, taking one exposure in 15 seconds (10s exposure + 5s readout).\nThe limit magnitude is ~12 mag in R band. We estimate a 20.1% prior\nprobability that these 3 regions contain the true location of the\nsource.\n\nThe coordinates of the 3 regions and observation time are list following:\n\nstart-obs(UTC)  end-obs(UTC)    Ra      Dec     Camera_ID\n2017-06-08 16:58:35 2017-06-08 19:36:46 01:15:34.8 +70:03:21   C3\n2017-06-08 17:10:44 2017-06-08 19:31:01 01:22:21.1 +49:56:18   C4\n2017-06-08 19:10:51 2017-06-08 19:32:59 03:56:21.7 +69:30:35   C5\n\nThe covering map is available at:\nhttp://svom.bao.ac.cn/svomgwpub/skymap/G288732_skymap_miniGWAC.png\n(svom:gw2017@svom)\n\nThe first image (which is covered in our routine survey) was taken\n14 hours 57 minutes after the event trigger.\nNo any significant transient is found in our online pipeline.
