TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5637 SUBJECT: GRB060926: improved redshift DATE: 06/09/27 16:57:45 GMT FROM: Silvia Piranomonte at OAR V. D'Elia, S.Piranomonte (INAF/OAR), S. Covino (INAF/OABr), D. Malesani (SISSA/ISAS), F. Fiore, A. Antonelli (INAF/OAR), G. Tagliaferri (INAF/OABr), L. Stella (INAF/OAR), and G. Chincarini (Univ. Milano-Bicocca), report on behalf of the MISTICI collaboration: Using updated calibration files, we have refined the redshift obtained at the VLT for GRB 060926 (Piranomonte et al., GCN 5626; Holland et al., GCN 5612). We measure a redshift of z = 3.208 based on the detection of the following lines in absorption: Lyman-alpha, OI_1302 SiII_1304, CII_1334, CII_1347, SiIV_1393, SiIV_1402, SiII_1526, SiII*_1533, CIV_1540, CIV_1550, FeII_1608, FeII_1611, AlII_1670, and SiII_1808.
