GRB 170614A CALET Gamma-Ray Burst Monitor detection

The long-duration GRB 170614A (Fermi-GBM trigger #519133191; INTEGRAL SPI-ACS trigger #7869; Konus-Wind trigger time on 11:39:55.892) triggered the CALET Gamma-ray Burst Monitor (CGBM) at 11:39:43.86 on 14 June 2017. The burst signal was seen by the all CGBM instruments. The light curve of the SGM shows multiple peaks. The entire burst episode starts at T+~2 sec, peaks at T+~20 sec and ends at T+~40 sec. The T90 duration measured by the SGM data is 22 +- 1 sec (40-1000 keV). The light curve is available at http://cgbm.calet.jp/cgbm_trigger/flight/1181475101/ The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at the Waseda University.
