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

We have used the spectral parameters of the most intense part
of GRB 060105 provided by Golenetskii et al. (GCNC 4439) to
compute the spectral pseudo-redshift of this GRB, assuming that
the most intense part of the burst contains half of the total fluence.

We find a pseudo-redshift pz= 4.0 +/- 1.3
