TITLE: GCN CIRCULAR NUMBER: 22434 SUBJECT: GRB 180222A: A long GRB detected by INTEGRAL DATE: 18/02/22 14:19:25 GMT FROM: Sandro Mereghetti at IASF-Milano/INAF S.Mereghetti (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) on behalf of the IBAS Localization Team report: a gamma ray burst lasting about 20 s has been detected by IBAS in the IBIS/ISGRI data at 13:10:02 UT of February 22, 2018 The refined coordinates (J2000) are: R.A.= 256.5418 deg DEC.= -36.8016 deg with an uncertainty of 1.5 arcmin (90% c.l.). The burst had a peak flux of about 1 counts/cm2/s (20-200 keV, 1-s integration time) and a fluence in the same energy range of about 6e-7 erg/cmq. This burst was also detected by the Swift/BAT (Cannizzo et al., GCN 22433). A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html
