This is the first GRB triggered by GRM in-flight. The real-time alert data and light curves produced were downlinked to the ground through the VHF system with low latency. The light curve shows that this burst consists of a single peak with a duration of less than 0.8 s, indicating that it is a short burst. The GRM light curve can be found here: http://www.bursthub.cn//admin/static/svgrb240715A.png During this period, the SVOM/ECLAIRs was in configuration mode and did not collect scientific data, so there was no observation of this burst with ECLAIRs. 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.
