LIGO/Virgo G288732: AGILE MCAL Observations

In response to the LIGO/Virgo GW event G288732 at T0 = 2017-06-08 02:01:16.492 UTC, a preliminary analysis of the AGILE MiniCALorimeter (MCAL) data found no event candidates within a time interval covering approximately -/+ 10 sec from the LIGO T0. 3-sigma ULs were computed for a 1 s integration time on different celestial positions within the G288732 error region, for a typical value of the fluence of 6.4e-7 erg cm^-2 (assuming as spectral model a power law with photon index 1.4). The AGILE-MCAL detector is a CsI detector with a 4-pi FoV, working in the range 0.4 - 100 MeV. Additional analysis of AGILE data is in progress.
