report on behalf of GRAASP:

"We observed the afterglow of GRB 080310 with the Kast
dual spectrometer for a series of 900s exposures starting
at UT 09:06 under good conditions.  Analysis of the red side
reveals a series of strong absorption features (SiIV, CIV,
AlII 1670) consistent with the redshift z=2.4266.  At
present we consider this to be the redshift of GRB 080310.

Further analysis is in progress."
