and N. Kawai (Tokyo Tech) report:
We obtained R, I, and z' images of the afterglow of GRB030226(=H10893)
at Feb 26.65 (UT) with FOCAS attached to Subaru 8.2m telescope. The
R-band magnitude of the OT is derived to be 19.0+-0.2 using four stars
close to the OT in the USNO-A2.0 catalog.
With further analyses of the optical spectra reported in GCN 1882,
we find the highest redshift for the absorbers to be z=1.99.
