S. B. Cenko, J. S. Bloom, D. A. Perley, and B. E. Cobb (UC Berkeley)
report on behalf of a larger collaboration:

We have obtained spectra of the proposed host galaxy (Bloom and
Nugent, GCN 10433; Holland et al., GCN 10436) and the optical afterglow
(Jakobsson et al., GCN 10438; Kruehler et al., GCN 10439) of
GRB100219A (Rowlinson et al., GCN 10430) with the Gemini Multi-Object
Spectrograph mounted on the 8-m Gemini South telescope.  Our first
sequence of 2 x 900 s observations started at 2:44 UT on 20 February
2010 and cover the range from 6500 - 9500 A.  Only the proposed host
galaxy was contained on the slit for these spectra.  Our second set,
starting immediately afterward, cover the wavelength range from 4500 -
7500 A and both the proposed host and afterglow are positioned on the
slit.
