The long-duration GRB160223B (Gotz et al., GCN Circ. 19059; von Kienlin et al., GCN Circ. 19061)
triggered the CALET Gamma-Ray Burst Monitor (CGBM) at 09:58:59.5 on 23 February 2016.
The burst signal was detected by SGM instrument.
The light curve of the SGM shows at least three peaks. The emission starts at T0,
peaks at T0+1 sec and ends at T0+25 sec. The T90 duration measured by the SGM data
is 11 +- 1 sec (40-1000 keV).
The CGBM data used in this analysis are provided by the Waseda CALET Operation Center
located at the Waseda University.
