AbstractThe long GRB 190531B (Fermi-LAT detection: Axelsson et al.,GCN Circ. 24701; Fermi-GBM observations: Veres and Meegan, GCN Circ. 24705; Insight-HXMT/HE detection: Yi et al., GCN Circ. 24713; Konus-Wind observation: Svinkin et al., GCN Circ. 24730) triggered the CALET Gamma- ray Burst Monitor (CGBM) at 20:10:20.034 UTC on 31 May 2019. The burst signal was seen by all CGBM detectors. No real-time CGBM GCN notice was distributed about this trigger because the real-time communication from the ISS was off (loss of signal). The burst light curve shows a multi- peaked emission episode which starts at T-9.7 sec, peaks at 14.5 sec and ends at T+74.5 sec. The T90 and T50 durations measured by the SGM data are 36.8 +- 20.0 sec and 13.5 +- 0.9 sec (40-1000 keV), respectively. The ground processed light curve is available at http://cgbm.calet.jp/cgbm_trigger/ground/1243368627/ The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at the Waseda University.
