E. Berger (Harvard), report on behalf of a larger collaboration:

"We observed the field of GRB 100213B (Vetere et al., GCN 10412)
with GMOS on the Gemini-North 8-m telescope starting on 2010
Feb 14.24 (~7 hours after the burst).

Inside the refined XRT error circle (GCN #10416) we detect
no new sources in a 2 min r-band acquisition image.
Outside the XRT error circle we clearly detect the source
reported by Malesani et al. (GCN #10413).

We then obtain 2x1200s spectra on this source at central
wavelength 8000A. We detect [OII]3727, H-beta and [OIII]5007
at the common redshift of z =0.604.
At this point is not clear whether this object is related to
GRB 100213B.

We thank the Gemini staff for performing this observation, in
particular Tom Geballe."
