TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5170 SUBJECT: GRB 060526: Magellan Redshift DATE: 06/05/27 03:25:00 GMT FROM: Edo Berger at Carnegie Obs E. Berger and M. Gladders (Carnegie) report: "We obtained a spectrum of the optical afterglow of GRB 060526 (GCN 5162) with the LDSS3 spectrograph on the Magellan/Clay telescope starting on 2006, May 27.06 UT. The spectrum reveals a strong aborption feature which we identify as Ly-alpha, as well as a large number of aborption features corresponding to SII, SiII, CII, FeII, etc., at a redshift of 3.21. Further analysis is on-going"
