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

We have used the spectral parameters of GRB 060904A
provided by Golenetskii et al. (GCNC 5518) to
compute the spectral pseudo-redshift** of this burst
detected by SWIFT-BAT (trigger #227996:
Grupe et al., GCNC 5502; Krimm et al., GCN 5516).

We find a pseudo-redshift pz= 1.84 ± 0.85

We thank V. Pal'shin for providing the fluence of this GRB
during the main pulse (from T0 to T0+16.64 s, KONUS time).
