The short-duration GRB 160709A (Guiriec, et al., GCN circ. 19675;
Jenke, et al., GCN circ. 19676; Frederiks, et al. GCN circ. 19677)
triggered the CALET Gamma-ray Burst Monitor (CGBM) at 19:49:04.67
on 9 July 2016. No real time CGBM GCN notice was distributed about
this trigger because the real time communication from the ISS was
off (loss of signal) between 19:42 and 20:04. The burst signal was
seen by all CGBM instruments.
The light curve of the SGM shows a single starting at T-0.2 sec,
peaking at T0-0.1 sec and ending at T+0.2 sec. The T90 duration
measured by the SGM data is 0.38 +- 0.04 sec (600-3000 keV).
The light curve is available at

CALET Operation Center located at the Waseda University.
