Salvaggio, et al., GCN 38354). With the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that this burst consists of a single pulse with a duration of about 3 s. The SVOM/GRM light curve can be found here: https://www.bursthub.cn//admin/static/svgrb241127A.png This burst is located at about 75.6 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), the 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.
