Lachaud (APC) report on behalf of the SVOM mission team:\n\nAt 2026-04-10T12:22:27 UTC (T0), SVOM/GRM triggered on the gamma-ray burst GRB 260410B (SVOM burst-id sb26041001) on a timescale of 1 seconds and with a signal-to-noise ratio (SNR) of 5.90.\n\nThis transient was also detected by Fermi/GBM (GCN Circulars #44255).\n\nAt the time of this burst, SVOM/ECLAIRs was not taking data.\n\nWith the event-by-event data downloaded through the X-band ground station, the GRM light curve shows that the short burst GRB 260410B consists a single pulse with T90 of 0.20 +0.12/-0.06 s in the 15-5000 keV band. \n\nThe SVOM/GRM light curve can be found here:\nhttps://www.bursthub.cn//admin/static/svgrb260410B.png\n\nThe Space-based multi-band astronomical Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA), French Space Agency (CNES), and the Chinese Academy of Sciences (CAS), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe. SVOM/ECLAIRs was developed jointly by CNES, CEA-IRFU, CNRS-IRAP, CNRS-APC. SVOM/GRM was developed by the Institute of High Energy Physics (IHEP) of CAS. SVOM/MXT was developed jointly by CNES, CEA-IRFU, CNRS-IJCLab, University of Leicester, MPE.\n\nThe Burst Advocate (BA) on shift for this alert is Chenwei Wang: cwwang AT ihep.ac.cn.\nPlease contact the BA by email if you require additional information.\n",
