report on behalf of the SVOM team:
During the commissioning phase, the SVOM/GRM was triggered in-flight by a long GRB 240912A (SVOM trigger reference: sb24091203) at 2024-09-12T01:47:37.000 UT (T0), which also triggered Fermi/GBM (Fermi GBM team, GCN 37465), Swift/BAT (Evans et al., GCN 37466) and INTEGRAL SPI ACS (Pawar, GCN 37473).
With the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that this burst consists of multiple pulses with a duration of about 79 s.

The Space Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA, China), National Center for Space Studies (CNES, France) and the Chinese Academy of Sciences (CAS, China), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe. GRM is developed by the Institute of High Energy Physics (IHEP) of CAS.
