Johan P. U. Fynbo, Marceau Limousin, José María Castro Cerón,
Brian L. Jensen (DARK Cosmology Centre), Jyri Näränen (Helsinki
Observatory) report on behalf of a larger collaboration:
"From the calibrated ALFOSC spectrum of the afterglow of GRB 060206
(GCN #4682, #4683, #4684, #4686) we measure a redshift of
z=4.045 based on Lyman-alpha, SiII, SiII*, OI, CII and SiIV
among other lines. Our previous estimate was off due to a
calculation error for which we apologise."
