In response to the LIGO/Virgo GW event S191110af at T0 = 2019-11-10
23:06:44 (UT), analysis of AGILE data shows that the satellite at T0 was
in the South Atlantic Anomaly (SAA). Scientific telemetry was inhibited
during the time interval (T0 -700 s; T0 + 200 s).
At T0+200s we obtained a MCAL preliminary 3-sigma fluence upper limits
(UL) for a 1 s integration time t different celestial positions within
the accessible S191110af localization region, from a minimum of 1.46E-06
erg cm^-2 to a maximum of 6.76E-06 erg cm^-2 (assuming as spectral model
a single power law with photon index 1.5).
The AGILE-MCAL detector is a CsI detector with a 4 pi FoV, sensitive in
the energy range 0.4 - 100 MeV. Additional analysis of AGILE data is in
progress.
