A. Cucchiara (UCSC), S. B. Cenko (UC Berkeley) report on behalf
of a larger collaboration:
"We obtained spectroscopy of the afterglow of the LAT-GRB 130518A
(Xiong et al. GCN 14674, Omodei et al. GCN 14675, Evans et al.
GCN 14678) with Gemini-North / GMOS, beginning a May 20.60 UT
roughly 2.05 days after the burst.
Two different central wavelengths were observed giving a coverage
from ~3850-6730 A.
We identify several absorption features, including Lyman-alpha,
SiIV(1394,1402), SiII1526, and CIV(1548,1550) at the common
redshift of z=2.488.
This result is consistent with the one reported by S�nchez-Ram�rez
et al. (GCN 14685).
We thank the Gemini-staff for their help in performing these
observations."
