Kawai (Tokyo Tech) report:\n\nWe obtained R, I, and z' images of the afterglow of GRB030226(=H10893)\nat Feb 26.65 (UT) with FOCAS attached to Subaru 8.2m telescope.  The\nR-band magnitude of the OT is derived to be 19.0+-0.2 using four stars\nclose to the OT in the USNO-A2.0 catalog.\n\nWith further analyses of the optical spectra reported in GCN 1882, \nwe find the highest redshift for the absorbers to be  z=1.99.\n\nThis message may be cited.",
