TITLE:   GCN CIRCULAR
NUMBER:  12363
SUBJECT: GRB 110918A: pseudo-z=  from prompt emission spectrum

J-L. Atteia (IRAP-UPS/CNRS)&  A. Pelangeon report:

We used the spectral parameters of GRB 110918A provided by Golenetskii et al. (GCNC 12362)
to compute the spectral pseudo-redshift(**) of this burst localized by IPN (Pal'shin et al., GCNC 12358).

We find a pseudo-redshift pz= 0.28 +/- .07
