TITLE: GCN CIRCULAR NUMBER: 38573 SUBJECT: GRB 241215A: A long GRB detected by INTEGRAL DATE: 24/12/15 15:02:10 GMT FROM: Sandro Mereghetti at IASF-Milano/INAF <sandro.mereghetti@inaf.it> S.Mereghetti (INAF, IASF-Milano), D.Gotz (CEA, Saclay), C.Ferrigno, E.Bozzo, V.Savchenko (ISDC, Versoix), L.Ducci (IAAT, Germany and ISDC, Versoix) and J.Borkowski (CAMK, Torun) report: a gamma ray burst lasting about 30 s has been detected by IBAS in the IBIS/ISGRI data at 13:53:15 UT of 2024 December 15. The refined coordinates (J2000) are: R.A.= 10.5861 deg DEC.= +32.5190 deg with an uncertainty of 2.5 arcmin (90% c.l.). The burst had a peak flux of 0.5 ph/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 4e-7 erg/cmq. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html View this GCN Circular online at https://gcn.nasa.gov/circulars/38573. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0LW...
