TITLE: GCN GRB OBSERVATION REPORT NUMBER: 475 SUBJECT: GRB 991208 SAO-RAS Spectroscopy DATE: 99/12/17 20:52:14 GMT FROM: Vladimir Sokolov at SAO RAS S.N. Dodonov, V.L. Afanasiev, V.V. Sokolov, A.V. Moiseev (SAO-RAS) and Alberto J. Castro-Tirado (INTA, Madrid and IAA, Granada) report: "A BTA/MPSF 4500-s spectrum of the optical transient of GRB 991208 (GCN #452) was obtained on 14.14 Dec 1999 UT with the the SAO-RAS 6-m telescope. The observational conditions on 14 Dec were already given in GCN #461. The data were obtained with the integral field spectrograph (Multi Pupil Fiber Spectrograph, MPFS, http://www.sao.ru:8100/~gafan/devices/mpfs/mpfs_main.htm ) with 300 lines/mm grating blazed at 6000 A giving a spectral resolution of about 5 A/pix and effective wavelength coverage of 4100 - 9200 A. Emission lines at lambda = 6350 A, 8550 A and 8470 A are present, with the most likely identifications of these emission lines being: [OII] 3727 A, [OIII] 4959,5007 A at a redshift of z = 0.707 +/-0.002, presumably that of the host galaxy.
