Izzo (IAA), A.\nMelandri (INAF-OABr) on behalf of GRAWITA.\n\nWe observed the field of S190814bv (GCN 25324, GCN 25333) in r' band with\nthe VLT Survey Telescope (VST) equipped with Omegacam (1 sqdeg FOV)\n(Proposal ID ESO 0103.D-0070 ).\nIn the first night we imaged 18 sqdeg covering 65% of the localization\nprobability region. The observations started on 2019-08-15 at 08:50:26.860\nand ended at 10:13:47.602 UT. The seeing was below 2\" in thin conditions.\nIn the second epoch we modified the pointings to improve the updated skymap\ncoverage. The area imaged is 23 sqdeg covering 87% of the localization\nregion.\nThe observations started on 2019-08-16 at 05:29:37.904 and ended at\n07:20:36.231. The seeing went down to 0.5\" in thin conditions.\nEach 1 sqdeg pointing was observed three times for a total exposure time of\n135 seconds.\nAutomatic data processing was done with the VSTTube pipeline (Grado et al.\n2012 Mem.SAIt 19, 362).\nThe pointing sequence was generated using the GWsky script (\nhttps://github.com/ggreco77/GWsky).\nAnalysis of the images is in progress.\n\nWe acknowledge excellent support from the ESO User Support Department and\nfrom ESO observing staff in Paranal.",
