TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4086 SUBJECT: GRB 051008: - a high redshift high-luminosity burst? DATE: 05/10/11 15:50:20 GMT FROM: Jean-Luc Atteia at Lab d Astrophys.,OMP,Toulouse A. Pelangeon & J-L. Atteia (LAT-OMP) report: We have used the spectral parameters of the most intense part of GRB 051008 provided by Golenetskii et al. (GCNC 4078), to compute the spectral pseudo-redshift of this GRB. We find a pseudo-redshift pz= 5.2 +/- 1.3 We thank V. Pal'shin for providing the fluence of this GRB during the interval extending from T0 to T0+8.192 sec (KONUS time). This notice can be cited.
