TITLE: GCN CIRCULAR NUMBER: 7388 SUBJECT: GRB 080310: Lick/Kast Spectroscopy DATE: 08/03/10 10:13:12 GMT FROM: Jason Prochaska at UCO/Lick Obs J.X. Prochaska (UCSC), M. Murphy (Swinburne), A.L. Malec (Swinburne), K. Miller (Lick) 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." This GCN may be cited. ---------------------------------------------- Jason X.
