In response to the public LIGO/Virgo gravitational wave (GW) alert of the on-going osservative run O3, with trigger event name S190512at at T0 = 2019-05-12 18:07:14.422 (UT), the AGILE Team performed a quick look follow-up analysis of the AGILE data. The AGILE satellite at T0 was in the South Atlantic Anomaly (SAA), and the S190510g Ligo-Virgo 90% c.l. localization region was occulted by the Earth.

Preliminary MCAL results and AGILE GRID upper limits in the first time intervals available after the SAA have been published in two GCN CIRCULARS:
GCN #24507: LIGO-Virgo S190512at: AGILE MCAL observations (A. Ursi et al.)
GCN #24519: LIGO-Virgo S190512at: AGILE GRID observations (C. Pittori et al.)
