  "body": "Long-Hao Li, Chen-Yu Wang, Zi-Rui Yang report on behalf of the GRID Collaboration:\n\nGRID reports the detection of GRB 251213A, a long-duration gamma-ray burst, which was also detected by GECAM-B (GCN Circ.43106), SVOM/GRM and AstroSat CZTI (GCN Circ. 43108). The event triggered GRID-11B at T0 = 2025-12-13 12:30:04 UTC. The measured burst duration is T90 = 34.6 ± 2.8 s in the 30–2000 keV energy range.\n\nThe GRID light curve for this event is available at https://mirrors.tuna.tsinghua.edu.cn/GRID/data/GRID-GCN/GRB251213A/GRID_GRB251213A_ltcv.pdf. \n\nGRID is a student-led project to monitor the transient gamma-ray sky with multiple detectors onboard different nanosatellites in the era of multi-messenger astronomy.
