TITLE: GCN CIRCULAR NUMBER: 16231 SUBJECT: GRB 140508A: WHT spectroscopy DATE: 14/05/09 03:06:22 GMT FROM: Klaas Wiersema at U Leicester K. Wiersema (Leicester), N. Tanvir (Leicester), A. Levan (Warwick), R. Karjalainen (ING) report: We observed the afterglow candidate of GRB 140508A (Singer et al. GCN 16226) with the 4.2m William Herschel Telescope using the ACAM instrument. We acquired 3x600s spectroscopic exposures, with midpoint 23:02 UT on 8 May 2014. We find absorption lines of Mg II and Fe II at a common redshift of z=1.027, though we caution this redshift is based on archival wavelength calibrations. This is consistent with the redshift reported by Malesani et al. (GCN 16229).
