Report on behalf of the SVOM team:

During the commissioning phase, the SVOM/GRM was triggered in-flight by GRB 241104A at 2024-11-04T18:30:14 UT (T0), which was also observed by Fermi/GBM (Fermi GBM Team, GCN 38075) and SVOM/ECLAIRs (GCN 38078).

The real-time alert data and light curves of SVOM/GRM were downlinked to the ground through the VHF system with low latency. 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 T90 of 11.9 +0.3/-0.3 s.

The GRM light curve can be found here:

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.

The SVOM point of contact for this burst is: Jin-Peng Zhang (IHEP)(zhangjinpeng@ihep.ac.cn)
