TITLE: GCN CIRCULAR NUMBER: 8002 SUBJECT: GRB 080723B : a long GRB detected with INTEGRAL DATE: 08/07/23 14:28:26 GMT FROM: Diego Gotz at CEA D. Gotz (CEA-Saclay), A.Paizis, S.Mereghetti (IASF-Milano), V.Beckmann, M. Beck, A. Manousakis (ISDC, Versoix), and J. Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: A bright GRB lasting about 105 s has been detected by IBAS in IBIS/ ISGRI data at 13:22:19 UT on July 23rd 2008. The refined position is R.A.: 176.8354 deg Dec.: -60.2452 deg with an uncertainty of 1.5 arcmin (90% c.l.). The burst is very bright and has saturated the available telemetry share. Hence the following preliminary spectral results are to be considered lower limits. The peak flux over 3 s in the 20-200 keV energy range is 6 ph/cmsq/s, and the fluence integrated over the whole burst duration is 1.3e-5 erg/cmsq. A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html This message can be cited.
