The long GRB 231106A (Fermi GBM Final Real-time Localization: 
Fermi GBM team, GCN Circ. 34956) triggered the CALET Gamma-ray
Burst Monitor (CGBM) at 18:12:50.43 UTC on 6 November 2023
(http://cgbm.calet.jp/cgbm_trigger/flight/1383329517).
The burst signal was seen by all CGBM detectors.

The burst light curve shows a multi-peaked structure that starts
at T-8.5 sec, peaks at T+38.1 sec, and ends at T+80.9 sec.
The T90 duration measured by the SGM data are 61.6 +/- 6.3 
sec (40-1000 keV).

The ground-processed light curve is available at

http://cgbm.calet.jp/cgbm_trigger/ground/1383329517/index.html

The CALET data used in this analysis are provided by
the Waseda CALET Operation Center located at Waseda University.
