TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1809 SUBJECT: GRB 021211: VLT spectrum DATE: 03/01/15 10:39:40 GMT FROM: Daniele Malesani at Brera Astro. Obs. M. Della Valle (INAF-OAA), S. Benetti (INAF-OAPd), D. Malesani (SISSA), E. Mason (ESO), L.A. Antonelli (INAF-OAR), G. Cocozza, (INAF-OAR), S. Covino (INAF-OABr), D. Fugazza (INAF-TNG), G. Ghisellini (INAF-OABr), G.L. Israel (INAF-OAR), L. Stella (INAF-OAR), and V. Testa (INAF-OAR), on behalf of a larger Italian collaboration, report: A low resolution spectrum of the probable host galaxy of GRB 021211 (Fox & Price, GCN 1731; Crew et al., GCN 1734) was obtained under modest sky (cirrus) and seeing (between 0.6" and 1.4") conditions, starting on 2003 Jan 8.27, with UT4 (Yepun) + FORS2 at the ESO-VLT. The spectrum covers the range of wavelengths 6000A-11000A with a resolution of about 17A (grism 150I). The total exposure time was 4h. We obtained the spectrum for both the complex afterglow+host and the nearby galaxy 1.5" NE (e.g. Caldwell et al., GCN 1759), that we confirm to be at z=0.80 (Vreeswijk et al., GCN 1756 & 1767). We clearly detect the emission line at 7472.9A already found by Vreeswijk et al. (GCN 1785). In addition we have identified three additional emissions at 9722.0A, 9954.9A and 10022.8A. We interpret the four lines as due to [OII] 3727A, Hbeta and [OIII] at 4959A and 5007A in the rest frame of the host galaxy, observed at a redshift of z=1.004+-0.002. We thank the kind assistance of the staff at Paranal, in particular Riccardo Scarpa and Andreas Kaufer. This message can be cited.
