The measured burst duration (T90) in the 30-2000 keV range is approximately 22.2 +/- 3.0 seconds. \n\nThe GRID light curve of this event can be found at [GRID_GRB260223A_ltcv.pdf](https://mirrors.tuna.tsinghua.edu.cn/GRID/data/GRID-GCN/GRB260223A/GRID_GRB260223A_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.
