 We have obtained 9 unfiltered exposures (180-s each) of the GRB 030226
 error box (HETE #10893). The images were taken with the AT-64 telescope of
 Crimean Astrophysical observatory and cover the period  UT 17:58 - UT 19:26
 Feb 26, 2003.  We used CCD SBIG ST-8 with maximum of sensitivity in the red
 spectral band.
 
 In a co-added image the OT is visible at the position of reported by D. Fox
 et al. (GCN 1880Not found
 
 
).  The brightness was estimated in respect to the stars A
 and B (GCN 1885Not found
 
 
) as R~19.5 +/- 0.2.
