TITLE: GCN CIRCULAR NUMBER: 24507 SUBJECT: LIGO-Virgo S190512at: AGILE MCAL observations DATE: 19/05/12 20:02:58 GMT FROM: Alessandro Ursi at INAF/IAPS A. Ursi (INAF/IAPS), C. Pittori (SSDC, and INAF/OAR), M. Tavani (INAF/IAPS, and Univ. Roma Tor Vergata), M. Cardillo, C. Casentini, G. Piano (INAF/IAPS), F. Lucarelli, F. Verrecchia (SSDC, and INAF/OAR), A. Bulgarelli, V. Fioretti, N. Parmiggiani (INAF/OAS-Bologna), M. Pilia (INAF/OA-Cagliari), F. Longo (Univ. Trieste, and INFN Trieste), report on behalf of the AGILE Team: In response to the LIGO-Virgo GW event S190512at at T0 = 2019-05-12 18:07:14 (UT), a preliminary analysis of the AGILE minicalorimeter (MCAL) data found no data acquisitions related to the event, due to a complete Earth occultation of the S190512at 90% c.l. localization region. 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.
