Covino (INAF-Brera), L. Izzo (IAA) on behalf\nof GRAWITA.\n\nWe observed 45 sqdeg covering the field of S170701ah (LIGO/Virgo, B.\nPiotrzkowski\net al., GCN #24950, updated sky localization, B. Piotrzkowski et al., GCN\n#24987) in r' band with the VLT Survey Telescope (VST) equipped  with\nOmegacam (1 sqdeg FOV) (Proposal ID ESO 0103.D-0070(A)).\n\nObservations started at 08:08 UT on 2019-07-04 and ended at 10:27 on\n2019-07-04. They were performed under  seeing conditions between 0.49��� and\n0.8���,  at an airmass between 1.95 and 1.27. Each pointing covering 1 sqdeg\nwas observed twice for a total exposure time of 80 seconds.\nThe observations, that cover ~70% of the localization probability region,\n were organized in group of 3x3 deg, the coordinates of the center of each\ngroup are:\n\nRA(J2000) Dec(J2000)\n------------------------\n02:27:14.69 -11:58:35.5\n02:25:49.35 -08:58:35.5\n02:24:49.23 -05:58:35.5\n02:36:53.19 -05:58:35.5\n02:36:14.47 -02:58:35.5\n\nAnalysis of the images is in progress.\nWe acknowledge excellent support from the ESO User Support Department and\nfrom ESO observing staff in Paranal.",
