A. Pelangeon & J-L. Atteia (LATT-OMP) report:

We used the spectral parameters of the most intense
part of GRB 080122 provided by Golenetskii et al. (GCNC 7219)
to compute the spectral pseudo-redshift(**) of this burst
detected by the IPN (Hurley et al., GCNC 7211).

We find a pseudo-redshift pz= 1.93 +/- 0.25
