TITLE: GCN CIRCULAR NUMBER: 16310 SUBJECT: GRB 140512A: Redshift from NOT DATE: 14/05/19 21:17:34 GMT FROM: Antonio de Ugarte Postigo at IAA-CSIC A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), J. Gorosabel (IAA-CSIC,UPV-EHU), D. Xu (DARK/NBI), D. Malesani (DARK/NBI), G. Leloudas (DARK/NBI),P. Jakobsson (U. Iceland), T. Kruehler (ESO), A.A. Djupvik (NOT), E. Gafton (OKC, Stockholm Univ.) and T. Libbrecht (Stockholm Univ.) report on behalf of a larger collaboration: Following the photometric observations of the counterpart of GRB 140512A (Pagani et al. GCN 16249) from the 2.5 m NOT (+ALFOSC) reported by de Ugarte Postigo et al. (GCN 16253) we obtained spectroscopic data. Observations consisted in 2x1800s exposures using Grism #4, which covers the range from 3800 to 9100. The mean observing epoch was May 13, 3:18:50 UT (7.78 hrs after the burst). The spectrum presents absorption features consistent with FeII and MgII at a common redshift of z=0.725, which we consider the most probable redshift for this event.
