TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5563 SUBJECT: GRB 060912B: a long GRB detected with INTEGRAL DATE: 06/09/12 18:57:39 GMT FROM: Diego Gotz at IASF-CNR D.Gotz (CEA, Saclay), S.Mereghetti, A.Paizis (IASF-Milano), S.Soldi, N.Mowlavi, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: A GRB lasting about 200 s has been detected by IBAS in IBIS/ISGRI data at 17:33:40 UT on September 12, 2006. The coordinates (J2000) are: R.A.: 271.2167 [degrees], DEC.: -19.8804 [degrees] with an uncertainty of 2.5 arcmin (90% c.l.). The peak flux in the 20-200 keV is 0.08 ph/cmsq/s. The fluence in the same band is 6E-7 erg/cmsq. A plot of the light curve will be posted at http://ibas.mi.iasf.cnr.it/IBAS_Results.html This message can be cited.
