Kawai (Tokyo Tech) report:\n\nWe have obtained optical images and optical spectra of the afterglow\nof GRB030226 (=H10893) with FOCAS attached to Subaru 8.2m on Mauna Kea.\n\nR-, I-, and z'-band images taken at Feb 26.29 (UT) reveal the presence\nof the optical afterglow with an R magnitude of ~17.8 mag.  We derived\na position of RA=11:33:04.9, Dec=+25:53:55 (J2000) with an accuracy of\n1\" using the USNO A-2.0 catalog.\n\nWe have also taken optical spectra covering wavelength regions of\n3700-6000 A and 5800-10000 A at Feb 26.31 (UT) with an exposure time\nof 20 min. each.  The spectral resolutions are about R=1000.  The\noptical spectra show intergalactic absorption lines clearly; roughly\nderived the highest redshift absorbers are MgII 2800 and CVI 1550 at\nz=2.1, indicating that a redshift of GRB 030226 is 2.1 or larger.\n\nThis message may be cited.",
