Ra: 3.5 deg Dec: -18.5 deg Err: 5.9 deg (1-sigma, statistical only)According to the realtime alert data of GECAM-B, this burst mainly consists of a spike and a tail with a total duration of about 1 s. The time-averaged spectrum from T0-0.5 s to T0 could be adequately fit by a power law with high energy exponential cutoff function with a fluence of about 1.21E-6 erg/cm^2 in 20-1000 keV.
