A. M. Soderberg (Caltech), E. Berger (Carnegie), and B. P. Schmidt (ANU)
report on behalf of a larger collaboration:
"We obtained an optical spectrum of the afterglow of GRB 060218 (GCN 4775)
with GMOS on the Gemini-south telescope starting on 2006 Feb 21.024 UT,
for a total of 1800 sec. We confirm the presence of narrow emission lines
at z=0.033 (GCNs 4792,4803), as well as the presence of broad absorption
features similar to those seen in SN1998bw and other broad-lined
Type Ibc supernovae (GCN 4803).
A plot of our spectrum is available at:

Further observations are planned."
