Marrocchesi (U of Siena)\nand the CALET collaboration:\n\nThe long, bright GRB 180305A (Fermi-LAT detection: Axelsson &  Bissaldi,\nGCN circ. 22457; Fermi-GBM detection: Veres & von Kienlin, GCN circ. 22458;\nKonus-Wind detection: Svinkin et al., GCN circ. 22461) triggered the CALET\nGamma-ray Burst Monitor (CGBM) at 09:26:09.218 UTC on 5 March 2018.\nNo real time CGBM GCN notice was distributed about this trigger because\nthe real time communication from the ISS was off (loss of signal) between\n9:00 and 9:36.  The burst signal was seen by all CGBM detectors.\n\nThe burst light curve shows a single multi-peaked pulse which starts at T-0.5 sec,\npeaks at T+3.4 sec and ends at T+14.6 sec.  The T90 and the T50 durations measured\nby the SGM data are 10.0 +- 0.8 sec and 3.88 +- 0.13 sec (40-1000 keV), respectively.\nCGBM HV was turned off at ~T+95 sec due to entering the radiation belts,\nso no CGBM data are available from that time until ~T+1300 sec.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1204276876/\n\nOn March 2, the CGBM on-board event data capture end time was changed from\n8 sec to 512 sec, so from that time in the Event mode CGBM collects time tagged\nevents up to T0+512 sec, where T0 is the trigger time.\n\nThe CALET data used in this analysis are provided by the Waseda CALET\nOperation Center located at the Waseda University.",
