Hong (Nihon U.), on behalf of\nthe Suzaku WAM team, report:\n\nThe long GRB 090112B (van der Horst et al., GCN 8805) triggered the\nSuzaku Wide-band All-sky Monitor (WAM) which covers an energy\nrange of 50 keV - 5 MeV at 2009-01-12 17:30:14 UT (=T0).\n\nThe observed light curve shows multiple peaks and lasting from\nT0-1 s to T0+12 s with a duration (T90) of about 8 seconds. The fluence\nin 100 - 1000 keV was (5.2 +/- 0.3) x 10^-6 erg/cm^2. The 1-s peak\nflux measured from T0+3 s was 3.5 (+0.2/-0.3) photons/cm^2/s in the\nsame energy range.\n\nPreliminary result shows that the time-averaged spectrum from T0-1 s\nto T0+12 s is well fitted by a single power-law with a photon index\nof 2.46 +/- 0.14 (chi^2/d.o.f = 18/22).\n\nAll the quoted errors are at statistical 90% confidence level,\nin which the systematic uncertainties are not included.\n\nThe light curves for this burst are available at:\nhttp://www.astro.isas.jaxa.jp/suzaku/HXD-WAM/WAM-GRB/grb/trig/grb_table.html",
