report on behalf of the SVOM team:

During the commissioning phase, the SVOM/GRM detected a weak long GRB 240713A at 2024-07-13T02:02:40 UT (T0) with on-ground blind search using event-by-event data downloaded through the X-band ground station, which also triggered SVOM/ECLAIRs (ECLAIRs team, GCN 36854) and Fermi/GBM Sub-threshold Observation(Fermi GBM team, GCN 36856).

The GRM light curve shows that this burst consists of multiple pulses with a duration of about 60 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.
