TITLE: GCN CIRCULAR NUMBER: 12867 SUBJECT: GRB 120119A: MMT redshift confirmation DATE: 12/01/19 06:24:14 GMT FROM: Edo Berger at Harvard D. Milisavljevic, M. Drout, and E. Berger (Harvard) report: "We obtained an optical spectrum of GRB 120119A (GCN 12859) with the Blue Channel spectrograph mounted on the MMT 6.5-m telescope. In a single 1800 sec exposure covering 3500-8500 Ang we find a wide range of absorption features (from CII1335 to MgI2853) at a common redshift of z=1.728, confirming the results of Cucchiara & Prochaska (GCN 12865)."
