TITLE: GCN CIRCULAR NUMBER: 11654 SUBJECT: GRB 110206A: a long GRB detected by INTEGRAL DATE: 11/02/06 19:07:49 GMT FROM: Sandro Mereghetti at IASF/CNR S.Mereghetti, A.Paizis (IASF-Milano), D.Gotz (CEA-Saclay), J. Borkowski (CAMK, Torun), E. Bozzo, C.Ferrigno, M. Beck (ISDC, Versoix), 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 18:08:05 UT of February 6. Its refined coordinates (J2000) are: RA: 92.35535 [degrees] DEC: -58.8075 [degrees] with an uncertainty of 2 arcmin (90% c.l.). A preliminary analysis gives a 20-200 keV peak flux of about 1 ph/cm2 s (1 s integration time) A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html
