Chenyu Wang, Zirui Yang and Longhao Li report on behalf of the GRID Collaboration: 

GRID-03B reports the detection of the long-duration GRB 240306A, which was also detected by Fermi/GBM, Swift/BAT-GUANO and AstroSat CZTI (GCN Circular 35885, 35889 and 35892).

The event was triggered with GRID on 2024-03-06 at 06:45:48 UTC.  The measured burst duration (T90) in the 30-2000 keV range is approximately 10.0 ± 1.0 seconds. Due to its proximity to Earth's atmosphere in the view of GRID-03B, the spectral data from GRID for this event may not be accurate.

The GRID light curve of this event can be found at https://mirrors.tuna.tsinghua.edu.cn/GRID/data/GRID-GCN/GRB240306A/GRID_GRB240306A_ltcv.pdf.
