GCN Circular 8083
J.X. Prochaska (UCSC), D. Perley (UCB), A. Howard (UCB), H.-W. Chen (Chicago), G. Marcy (UCB), D. Fischer (SFSU), and C. Wilburn (Keck) report on behalf of GRAASP: "We observed the afterglow of GRB 080810 with the Keck/HIRES echelle spectrometer for a series of 1000s exposures starting at UT 13:47:50 under good conditions. A quick analysis of the 2D images reveals a Lyman limit system at ~3975Ang. We tentatively associate this feature with the host galaxy of GRB 080810 and estimate a redshift z_GRB = 3.35. Further analysis is in progress." This GCN may be cited.
