The 10-m Southern African Large Telescope (SALT), currently
undergoing Performance-
Verification, observed the afterglow of GRB 060605 (Page et al.; GCN
5221) on Jun 6, 2006
at 00:53 UT with the Robert Stobie Spectrograph. The Lyman limit was
detected at 4300
Angstroms. We can therefore verify that the absorption feature
reported by Schmidt (GCN
5223) is indeed Ly alpha, which we centroid at 5720 Angstroms. This
line and the Ly limit
indicate that the source redshift is z = 3.7.
