TITLE: GCN CIRCULAR NUMBER: 44257 SUBJECT: GRB 260410A: SVOM/GRM detection of a short faint burst DATE: 26/04/10 15:59:54 GMT FROM: SVOM_group <svomgroup@bao.ac.cn> Chen-Wei Wang (IHEP), F. Piron (LUPM) and C. Lachaud (APC) report on behalf of the SVOM mission team: At 2026-04-10T12:22:27 UTC (T0), SVOM/GRM triggered on the gamma-ray burst GRB 260410A (SVOM burst-id sb26041001) on a timescale of 1 seconds and with a signal-to-noise ratio (SNR) of 5.90. This transient was also detected by Fermi/GBM and Fermi/LAT (GCN Circulars #44252 and #44253). At the time of this burst, SVOM/ECLAIRs was not taking data. The SVOM/GRM light curve shows a single narrow peak structure with a duration of about 0.5 s. SVOM did not slew to the burst. An exceptional ToO observation has been scheduled which started about 3 hours after the trigger time. The 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. The Burst Advocate (BA) on shift for this alert is Chenwei Wang: cwwang AT ihep.ac.cn.
