GRB 240828A: SVOM/GRM observation

During the commissioning phase, the SVOM/GRM detected a long GRB 240828A at 2024-08-28T14:55:07.200 UT (T0), which was also observed by Fermi/GBM (Fermi GBM team, GCN #37317; S. 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. The SVOM/GRM point of contact for this burst is: Yan-Qiu Zhang (IHEP)(zhangyanqiu@ihep.ac.cn)
