The images were taken with the AT-64\ntelescope  of Crimean Astrophysical observatory and cover the period  UT\n22:04 Mar. 1 - 01:44 Mar. 2, 2004.  We used CCD SBIG ST-8 with maximum of\nsensitivity in the red spectral band.  No afterglow candidate was  found in\ncomparison with DSS2. We estimated the limiting magnitudes of combined\nimages (S/N=3) as following\n\nStart time (UT)       telescope   exposure    limiting mag.\nMar. 29  22:04        AT-64     10x120 s      20.0\n\nThis message can be cited.",
