Report on behalf of the SVOM team:

SVOM/GRM was triggered on-ground by GRB 260711A at 2026-07-11T06:05:23.000 UTC (T0).

With the event-by-event data downloaded through the X-band ground station, we conducted the standard analysis pipeline of GRB 260711A. The GRM light curve shows that this burst consists of multiple pulses with a T90 of 12.5 +4.5/-3.5 s in the 15-5000 keV band.
