The long-duration GRB 170708B (Konus-Wind trigger time on
20:37:00.639 UT) triggered the CALET Gamma-ray Burst Monitor (CGBM)
at 20:36:54.18 on 8 July 2017. The burst signal was only seen by the SGM
The light curve of the SGM shows a single peak. The emission starts at T+2 sec,
peaks at T+4 sec and ends at T+9 sec. The T90 duration measured by the SGM
data is 5.6 +- 0.7 sec (40-1000 keV).
The light curve is available at
The CALET data used in this analysis are provided by the Waseda
CALET Operation Center located at the Waseda University.
