We have obtained 8 exposures (180-s each) of the GRB 030226

In a co-added image the OT is clearly visible at the position reported by D.
Fox et al. (GCN 1880).  The brightness was estimated in respect to the stars 
A and B of GCN 1885 (P. Garnavich et al), using photometry by A. Henden (GCN
1916):
