D. A. Perley and J. S. Bloom report,
On the night of 21 November 2006 (UT), we began spectroscopic
observations of GRB061121 at 15:35 UT using Keck I (+LRIS). The optical
afterglow is visible in the finder camera in early twilight and is
detected in 120-second spectroscopic exposures down to the atmospheric
cutoff. Strong absorption features are observed. Observations are
continuing.
