SVOM/GRM detection of a short burst from SGR 1830

During the commissioning phase, the SVOM/GRM detected a short burst from SGR 1830 at 2024-11-26T05:12:17.500 UT (T0), which was also observed by GECAM-B (C. Zheng, et al., GCN 38326). 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 0.08 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. The SVOM point of contact for this burst is: Chao Zheng (zhengchao97@ihep.ac.cn)
