Trois (INAF/OA-Cagliari), I. Donnarumma (ASI), report on behalf of the AGILE Team: The Gamma-Ray Imaging Detector (GRID) of AGILE detected a gamma-ray transient temporally coincident with the long�� GRB 220624A reported by Fermi/GBM in GCN #32256 and also detected by AGILE/MCAL (Ursi et al., GCN #32259). A preliminary GRID analysis shows a detection with a statistical significance above 8 sigma over a time integration of 20 s starting from the T0 of GRB 220624A, at a sky position compatible with that of the GRB. We obtained 25 events 2 of which are notably above 1 GeV. The GRB position was about 30 deg off-axis from the GRID boresight. These measurements were obtained with AGILE observing a large portion of the sky in spinning mode. Additional analysis of AGILE data is in progress.
