Tempesta (TeleSpazio), report on\nbehalf of the AGILE Team:\n\nhe Gamma-Ray Imaging Detector (GRID) of AGILE detected gamma-ray\ntransient emission consistent with the long GRB 220624A reported\nby Fermi/GBM (GCN #32256) at T0 = 2022-06-24 02:58:35 s (UTC),\nas already reported in Verrecchia et al. GCN #32261 and also\ndetected by AGILE/MCAL (Ursi et al., GCN #32259).\nAn improved localization has been reported by the IPN (Kozyrev\net al. GCN #32265).\n\nA refined AGILE/GRID data analysis in the energy range 30 MeV - 10\nGeV shows a detection with a statistical significance of about 10\nsigma over a time integration of 20 s starting at the T0 of GRB\n220624A, at a sky position with Galactic coordinates l=260 deg,\nb=75 deg, with and an error radius of 4 deg (90% statistical +\nsystematic error; R.A.= 182 deg, Decl.= 16 deg (J2000)).\n\nThe GRID error circle includes the IPN position.\nDuring the 20s integration, we detected a total of 41 events (3\nbackground events estimated through a Li&Ma analysis), 17 events at\nenergies above 100 MeV, and 3 events above 1 GeV.\n\nThese measurements were obtained with AGILE observing a large\nportion of the sky in spinning mode. Additional analysis of AGILE\ndata is in progress.",
