TITLE: GCN CIRCULAR NUMBER: 6823 SUBJECT: GRB 070925: a long GRB detected by INTEGRAL DATE: 07/09/25 17:26:59 GMT FROM: Sandro Mereghetti at IASF/CNR S.Mereghetti, A.Paizis (IASF-Milano), D.Gotz (CEA-Saclay), D.Petry, V.Beckmann, M. Beck (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: A GRB lasting about 30 s has been detected by IBAS in IBIS/ISGRI data at 15:52:32 UT of September 25. The coordinates (J2000) are: RA: 253.218 [degrees] DEC: -22.0355 [degrees] with an uncertainty of 2 arcmin (90% c.l.). The light curve is affected by gaps due to telemetry saturation. The peak flux in the 20-200 keV range is 2 ph/cmq/s (1-s integration time) and the fluence over the same energy range is larger than 2x10e-6 erg/cmq. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html This message can be cited.
