A. Pelangeon & J-L. Atteia (LATT-OMP) report:
We have used the spectral parameters of GRB 070220
provided by Golenetskii et al. (GCNC 6124) to compute the spectral
pseudo-redshift** of this burst detected by SWIFT-BAT
(Stamatikos et al., GCNC 6114; Parsons et al., GCNC 6121).
We find a pseudo-redshift pz= 2.15 � 0.80
