The short-duration GRB 160408A (Swift, Evans et al. GCN Circ. 19260;
Fermi-GBM, Roberts et al. GCN Circ. 19265; INTEGRAL-ACS, Trigger #7441)
triggered the CALET Gamma-Ray Burst Monitor (CGBM) at 6:25:37.4 on
8 April 2016. The burst signal was detected by all CGBM instruments.
The light curve of the SGM shows a single peak. The emission starts at T0+6.4 sec,
peaks at T0+6.5 sec and ends at T0+7.1 sec. The T90 duration
measured by the SGM data is 0.38 +- 0.18 sec (40-1000 keV).
The CGBM data used in this analysis are provided by the Waseda CALET Operation Center
located at the Waseda University.
