and the CALET collaboration:
The long-duration GRB 151210B (Fermi-GBM trigger #471401960) triggered the CALET
Gamma-Ray Burst Monitor (CGBM) at 00:59:20.12 UT on 10 December 2015. The burst
was detected by all three CGBM instruments.
The light curve of the Soft Gamma-ray Monitor (SGM; 30 keV - 20 MeV) shows the main
peak starting from T0-3 sec, peaking at T0 and ending at T0+~40 sec.
The T90 duration measured by the SGM data is 39 +- 3 sec (40-460 keV).
Currently, CALET is in the commissioning phase. Further information about CALET and
CGBM can be found at http://calet.jp/en/ and http://www.en.yoshida-agu.net/research/calet-gbm
