Schimp (Bergische Universitat, Wuppertal, Germany)\non behalf of the Pierre Auger Collaboration.\n\nIn response to the LIGO/Virgo GW trigger G296853\n(GCN #21431, T0=2017-08-09 08:28:21.747 UTC):\n\nWe searched for Ultra High Energy (UHE) neutrinos with energies\nabove ~ 1e17 eV in data collected with the Surface Detector (SD) of\nthe Pierre Auger Observatory in a [-500,500] second interval about\nthe LIGO-Virgo trigger G296853 as well as 1 day after it.\n\nNO events survived the cuts applied to reject the background due to UHE\nCosmic Rays i.e. NO neutrino candidates were detected.\n\nThe field of view (fov) where the SD of Auger is sensitive to UHE neutrinos\n(corresponding to inclined directions with respect to the vertical relative\nto the ground) was NOT coincident with the LIGO 90% localization region at\nthe\ntime T0 of the merger alert. The LIGO 90% localization region maximally\noverlapped with the Auger fov for the first time ~ 7 hours after the merger.\n\nThe Pierre Auger Observatory is an UHE Cosmic Ray detector\nlocated in the Mendoza Province in Argentina. It consists of an array\nof Water Cherenkov detectors spread over a total surface of 3000 km^2\narranged in a triangular grid of 1.5 km side as well as Fluorescence\ntelescopes and other systems (see 10.1016/j.nima.2015.06.058\nfor more information).\nFor neutrino searches from GW events with Auger, please refer to:\nhttps://journals.aps.org/prd/pdf/10.1103/PhysRevD.94.122007",
