GRB 190610A: CALET Gamma-Ray Burst Monitor detection
Abstract
The short GRB 190610A (Swift-BAT trigger #907754: Evans et al., GCN Circ. 24775, Palmer et al., GCN Circ. 24783; Insight-HXMT/HE detection: Cai et al., GCN Circ. 24782) triggered the CALET Gamma-ray Burst Monitor (CGBM) at 11:27:45.359 UTC on 10 June 2019. The burst signal was seen by all CGBM detectors. The burst light curve shows a single pulse which starts at T+0.58 sec, peaks at T+0.83 sec and ends at T+1.41 sec. The T90 and T50 durations measured by the SGM data are 0.61 +- 0.16 sec and 0.26 +- 0.05 sec (40-1000 keV), respectively. The ground processed light curve is available at http://cgbm.calet.jp/cgbm_trigger/ground/1244201256/ The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at the Waseda University.
