Leicester) report on behalf\nof a larger collaboration:\n\nUsing FORS2 on the Very Large Telescope, we have obtained a 10 min\nspectrum (grism 300V) of the optical afterglow of GRB 080210 (Grupe et\nal., GCN 7281).\n\nThe acquisition image shows the UVOT optical afterglow candidate to\nhave R = 18.8 on Feb 10.351 UT (0.597 hours after the GRB) using\nphotometric zeropoints from the ESO webpages. We also obtained an\nR-band image at 1.65 hours after the GRB indicating a decay index of\n0.76 +/- 0.04.\n\nThe spectrum is rich in absorption features, including Ly-alpha, Si II, \nC II, Si IV, C IV, Fe II and Al II, corresponding to a redshift of\nz = 2.641. This is consistent with the redshift upper limit (z < 3.5)\nreported by GROND (Kuepcue Yoldas et al., GCN 7283). There is also a\ntentative detection of Ly-alpha in emission superimposed on the DLA\ntrough.\n\nWe thank the Paranal staff for excellent support, especially Paul\nLynam.",
