report on behalf of the SVOM team:

During the commissioning phase, the SVOM/GRM was triggered by GRB 241113B(SVOM trigger reference: sb24111301) at 2024-11-13T11:23:05 UT (T0), which was also triggered by SVOM/ECLAIRs (Dagoneau et al, GCN 38196).

With the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that this burst consists of one pulse, with a T90 of 11.7 +1.9/-3.0 s (15-550 keV). This burst is located at about 23.8 degrees from the SVOM optical axis.

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.
