TITLE: GCN CIRCULAR NUMBER: 29429 SUBJECT: GRB 210208A: A long GRB detected by INTEGRAL DATE: 21/02/08 14:22:35 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 3 s has been detected by IBAS in the IBIS/ISGRI data at 13:32:23 UT of February 8, 2021. The refined coordinates (J2000) are: R.A.= 260.1976 deg DEC.= -12.6667 deg with an uncertainty of 2 arcmin (90% c.l.). The burst had a peak flux of about 0.9 counts/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 2e-7 erg/cm2. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html
