Marrocchesi (U of Siena),\nand the CALET collaboration:\n\nThe long GRB 220612A (Swift/BAT-GUANO detection: DeLaunay et al.,\nGCN Circ. 32198) triggered the CALET Gamma-ray\nBurst Monitor (CGBM) at 06:55:22.451 UTC on 12 June 2022\n(http://cgbm.calet.jp/cgbm_trigger/flight/1339051922/index.html).\nThe burst signal was faintly seen by only the SGM detector.\n\nThe light curve of the SGM shows two weak pulses.  The emission starts\nat T+2.8 sec, peaks at T+6.2 sec, and ends at T+19.7 sec.\nThe T90 and T50 durations measured by the SGM data are 15.0 +/- 1.0 sec\nand 8.0 +/- 1.4 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1339051922/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
