report on behalf of the SVOM team:
During the commissioning phase, SVOM/GRM was triggered in-flight by GRB 241126A (SVOM trigger reference: sb24112601) at 2024-11-26T05:04:16.000 UT (T0).
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 60 seconds.
