A. Pelangeon & J-L. Atteia (LATT-OMP) report:
We have used the spectral parameters of the most intense
part of GRB 070420 provided by Golenetskii et al. (GCNC 6344)
to compute the spectral pseudo-redshift** of this burst
detected by SWIFT-BAT (Stamatikos et al., GCNC 6330).
We find a pseudo-redshift pz= 1.56 +/- 0.35
