Shimizu, T. Tamura (Kanagawa U), \nM. L. Cherry (LSU), S. Ricciarini (U of Florence), P. S. Marrocchesi (U of Siena) \nand the CALET collaboration:\n\nThe long-duration GRB 151231A (Veres et al. GCN Circ. 18787) triggered the CALET \nGamma-Ray Burst Monitor (CGBM) at 10:37:53.15 UT on 31 December 2015.  The \nclear burst signal was detected by all instruments.  \n\nThe light curve of the SGM shows two main peaks.  The first peak starts at T0-2 sec, \npeaks at T0 and ends at T0+5 sec.  The second peak starts at T0+50 sec, peaks at \nT0+60 sec and ends at T0+70 sec.  The T90 duration measured by the SGM data is \n66.0 +- 0.7 sec (40-1000 keV).  \n\nThe CGBM data used in this analysis are provided by the Waseda CALET Operation Center \nlocated at the Waseda University.",
