Hong, K.Onda, M.Tashiro (Saitama U.), \nR.Miyawaki, M.Kokubun, K.Makishima (Univ. of Tokyo) \nand the HXD-II team\n\nThe long burst, GRB 060111B (Swift-BAT trigger #176918; \nPerri et al., GCN 4487), triggered the Suzaku Wide-band \nAll-sky Monitor (WAM) which is sensitive to an energy band \nof 50 keV - 5 MeV at 20:15:41 (UT). \nThe WAM light curve exhibits a double peak structure\n with a duration (T90) of 25 seconds. \nThe fluence in 100 - 1000 keV was (5.6 +/- 0.8)X10^-6 erg/cm2. \nThe 1-s peak flux was 1.0 +/- 0.2 photons/cm2/s \nin the same energy range.\n\nPreliminary result shows that the time-averaged spectrum \nis well fitted by a single power law with a photon index \nof 1.5 +/- 0.3.\n\nAll the quoted errors are at statistical 90% confidence level.\nThe WAM in-flight calibration is still under way, and systematic \nerrors, such as the flux calibration uncertainties of about 20%, \nare not included in the errors.\n\nThe WAM light curve of this event is available at \nhttp://www.astro.isas.ac.jp/suzaku/research/HXD-WAM/WAM-GRB/grb/grb_table.html\n\nFurther detailed analysis and the refinement are in progress.",
