Goettingen), on behalf of the GRACE collaboration\n\nreport:\n\nThe afterglow of the HETE burst (H10893) GRB 030226 (Fox et al., GCN 1879;\nPrice et al., GCN 1880) was observed with the VLT Yepun and the FORS2 \nspectrograph, equipped with the 300V grism on Feb. 26, beginning at 08:52 UT. \nThe total exposure time was 15 min. In the calibrated spectrum, covering \nthe 360-900 nm region, we clearly identify two distinct absorption-line \nsystems of Fe II (160.8), Al II (167.1) and CIV (154.8) at redshifts \nz=1.962+/-0.001 and 1.986+/-0.001, improving earlier findings \n(Ando et al., GCN 1884). We conclude that the redshift of the burster \nis z=1.986+/-0.001 or larger.\n\nWe are grateful for the assistence of the staff at Paranal.",
