TITLE: GCN CIRCULAR NUMBER: 28419 SUBJECT: GRB 200914A : A long GRB detected by INTEGRAL DATE: 20/09/14 13:32:19 GMT FROM: Sandro Mereghetti at IASF-Milano/INAF 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 70 s has been detected by IBAS in the IBIS/ISGRI data at 12:48:30 UT of 2020 September 14. The refined coordinates (J2000) are: R.A.= 254.512 deg DEC.= -36.2914 deg with an uncertainty of 1.5 arcmin (90% c.l.). The burst had a peak flux of about 2 counts/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 3e-6 erg/cmq. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html
