TITLE:   GCN CIRCULAR
NUMBER:  7384
SUBJECT: GRB 080310:  Magellan redshift
DATE:    08/03/10 09:16:48 GMT
FROM:    Edo Berger at Princton U  <eberger at astro.princeton.edu>

E. Berger (Carnegie/Princeton) and M. Rauch (Carnegie) report:

"We obtained a spectrum of the optical afterglow of GRB 080310 (GCNs 7381, 
7382) using the MagE spectrograph on the Magellan/Clay 6.5-m telescope. 
>From preliminary analysis we determine a redshift of about 1.7 based on 
broad Ly-alpha absorption at ~3300A.  Further observations and analysis 
are on-going."
