Report on behalf of the SVOM team:
SVOM/GRM was triggered in-flight by GRB 261001A (SVOM trigger reference: sb26100101) at 2026-10-01T12:52:20.000 (T0), which is also detected by GECAM-B (Xing-Hao Luo et. Al., GCN #45817).
With the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that this burst consists of muplti-pulses with a T90 of 36 +/-3 s in the 15-5000 keV band.

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.
