GCN Circular 1884
M. Ando, K. Ohta, C. Watanabe (Kyoto Univ.), K. Aoki, Y. Ohyama, K. S. Kawabata, S. Harasawa, D. Scarla (Subaru NAOJ), 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. This message may be cited.
