TITLE: GCN CIRCULAR NUMBER: 24379 SUBJECT: LIGO/Virgo S190503bf: AGILE MCAL observations DATE: 19/05/03 21:03:47 GMT FROM: Alessandro Ursi at INAF/IAPS A. Ursi, G. Piano (INAF/IAPS), M. Tavani (INAF/IAPS, and Univ. Roma Tor Vergata), M. Cardillo, C. Casentini (INAF/IAPS), F. Lucarelli, C. Pittori, 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 S190503bf at T0 = 2019-05-03 18:54:04 (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 S190503bf 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.
