TITLE: GCN CIRCULAR NUMBER: 11562 SUBJECT: GRB 110112B: A short GRB detected by INTEGRAL DATE: 11/01/13 10:34:53 GMT FROM: Sandro Mereghetti at IASF/CNR S.Mereghetti (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 short gamma ray burst lasting about 0.5 s has been detected by IBAS in the IBIS/ISGRI data at 22:24:54.6 UT of January 12. The detection significance was slightly below the threshold for automatic alert delivery. Its refined coordinates (J2000) are: RA: 10.599 [degrees] DEC: 64.406 [degrees] with an uncertainty of 2.6 arcmin (90% c.l.). A preliminary analysis gives a 20-200 keV fluence of about 1e-7 erg/cm2 and a peak flux of about 5 ph/cm2 s (0.1 s integration time) A plot of the light curve will be posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html NOTE: Automatic distribution of sky coordinates of low significance INTEGRAL IBAS triggers is currently under testing. This service will soon be made available to the interested users.
