Trieste, and INFN Trieste), report on\nbehalf of the AGILE Team:\n\nIn response to the LIGO/Virgo GW event S200225q at T0 = 2020-02-25\n06:04:21.397 (UT), a preliminary analysis of the AGILE minicalorimeter\n(MCAL) triggered data found no significant event candidates within a time\ninterval covering -/+ 15 sec from the LIGO/Virgo T0.\n\nAt the T0, about 45% of the S200225q 90% c.l. localization region (LR) was\naccessible to the AGILE/MCAL.\n\nThree-sigma upper limits (ULs) are obtained for a 1 s integration time at\ndifferent celestial positions within the accessible S200225q LR, from a\nminimum of 1.7E-06 erg cm^-2 to a maximum of 8.0E-06 erg cm^-2 (assuming as\nspectral model a single power-law with photon index 1.5).\n\nAn independent procedure based on photon counting statistics provides UL\nfluences in the range 0.4-1 MeV, for a 300 us integration time, from a\nminimum of 1.1E-08 erg cm^-2 to a maximum of 4.4E-08 erg cm^-2.\n\nThe AGILE/MCAL detector is a CsI detector with a 4 pi FoV, sensitive in the\nenergy range 0.4-100 MeV. Additional analysis of AGILE data is in progress.",
