Dalessi et al., GCN #37341), AstroSat CZTI (S. Srijan et al., GCN #37328), Fermi-LAT (R. Gupta et al., GCN #37331), GECAM (Yan-Qiu Zhang et al., GCN #37377) and INTEGRAL/SPI-ACS (trigger #10876). At the time of this burst ECLAIRs was not acquiring data. With the event-by-event data downloaded through the X-band ground station, the light curve shows that this burst consists of multiple pulses with a duration of about 45 s.

GRM is developed by the Institute of High Energy Physics (IHEP) of CAS.
