TITLE: GCN CIRCULAR NUMBER: 5751 SUBJECT: GRB 061025: a long GRB detected by INTEGRAL DATE: 06/10/25 19:48:15 GMT FROM: Sandro Mereghetti at IASF/CNR S.Mereghetti, A.Paizis (IASF-Milano), D.Gotz (CEA, Saclay), S.Shaw, M.Beck, I.Kreykenbohm (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: A GRB lasting about 20 s has been detected by IBAS in IBIS/ISGRI data at 18:35:50 UT on October 25, 2006. The coordinates (J2000) are: RA: 300.9121 [degrees], DEC: -48.2442 [degrees] with an uncertainty of 2 arcmin (90% c.l.). The peak flux in the 20-200 keV is 1.3 ph/cmq/s (1.5x10e-7 erg/cmq/s) over 1 s integration time and the fluence in the same energy range is 8x10e-7 erg/cmq A plot of the light curve will be posted at http://ibas.mi.iasf.cnr.it/IBAS_Results.html This message can be cited.
