  "body": "Longhao Li, Chenyu Wang, Zirui Yang report on behalf of the GRID Collaboration:\n\nGRID reports the detection of GRB 260225D, which was also observed by Glowbug (GCN #43856) and SVOM/GRM(GCN #43885).\n\nThe event triggered GRID at T0 = 2026-02-25 19:51:28.7 UTC and was detected by both GRID-09B and GRID-11B, with a weaker signal observed by GRID-11B. Temporal analysis based on GRID-09B data yields a burst duration of T90 = 1.96 ± 0.08 s in the 30–2000 keV energy range.\n\nAt present, only the GRID light curve is available. No spectral analysis is reported at this stage. The GRID light curve of this event can be found at https://mirrors.tuna.tsinghua.edu.cn/GRID/data/GRID-GCN/GRB260225D/GRID_260225D_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.
