P. Minaev (IKI), A. Pozanenko (IKI) report on behalf of GRB IKI FuN:
We analysed spectral data of GBM/Fermi of GRB 210323A (Hamburg et al.,
GCN 29709) which is initially reported in for GRB 210323A (Gropp et al.,
GCN 29699; Hamburg et al., GCN 29709) to classify the burst and estimate
its redshift using EH-T90,i diagram [1,2]. The burst belongs to type I
(short) population. We also estimate the lower limit on redshift of z =
0.42.
