GRB 230625B: CALET Gamma-Ray Burst Monitor detection
Abstract
The long GRB 230625B (Swift/BAT-GUANO Detection: Ronchini et al., GCN Circ. 34083; AstroSat CZTI detection: Navaneeth et al., GCN Circ. 34119) triggered the CALET Gamma-ray Burst Monitor (CGBM) at 07:28:45.62 UTC on 25 June 2023 (http://cgbm.calet.jp/cgbm_trigger/flight/1371713313/index.html). The burst signal was seen by all CGBM detectors. The burst light curve shows multi-peaked structure that starts at T-2.0 sec. The whole episode was not seen by CGBM because the sequence of the HV turn-off started from T+220 sec. The ground-processed light curve is available at http://cgbm.calet.jp/cgbm_trigger/ground/1371713313/ The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at Waseda University.
