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

We have used the spectral parameters of GRB 060928
provided by Ohno et al. (GCNC 5688) and
Golenetskii et al. (GCNC 5689) to compute
the spectral pseudo-redshift** of this burst
localized by IPN (Hurley et al., GCNC 5684).

- With the parameters of Suzaku/WAM we find
a pseudo-redshift pz= 2.30 +/- 0.70

- With the parameters of Konus-Wind we find
a pseudo-redshift pz= 2.20 +/- 0.45
