Trieste, and\nINFN Trieste), report on behalf of the AGILE Team:\n\nIn response to the LIGO/Virgo GW event S190602aq at T0 = 2019-06-02 17:59:27.089\nUTC (GCN #24717) a preliminary analysis of the AGILE exposure at T0 showed\n that\nthe S190602aq 90% c.l. localization region (LR) was not exposed by the Gamma-Ray\nImaging Detector (GRID). The closest exposure in time occurred at T0+100s\ncovering\nabout 100% of the LR at off-axis angles between 20 and 70 deg.\n\nWe performed an analysis of the GRID data in the energy range 50 MeV - 10 GeV\nover a single time interval after T0, when good exposure of\nthe S190602aq 90% c.l. LR was available. The following preliminary GRID 3-sigma upper limit (UL) values\nare obtained over a large area of the exposed LR:\n(T0+100s; T0+200s): from 3.0e-08 to 4.7e-07 erg cm^-2 s^-1\n\nAn image of the AGILE-GRID 100s exposure near T0 is available at the site\nhttps://tools.ssdc.asi.it/ImgView/Agile/S190602aq_T0+100s_d100s_FM_UL-E50la17\n\nThese measurements were obtained with AGILE observing a large portion of\nthe sky in\nspinning mode. Additional analysis of AGILE data is in progress.",
