TITLE:   GCN CIRCULAR
NUMBER:  8143
SUBJECT: GRB 080825B: pseudo-z= 0.83 from prompt emission spectrum

We used the spectral parameters of GRB 080825B
provided by Golenetskii et al. (GCNC 8142) to compute
the spectral pseudo-redshift(**) of this burst localized
by SuperAGILE (Evangelista et al., GCN 8133).

We find a pseudo-redshift pz= 0.83 ± 0.30
