Several unfiltered images with exposures of 120 s\nwere obtained in Apr. 29 between (UT) 18:19 and 20:57.  The OT found by\nA.Gilmore at al. (GCN 2184) is marginally visible in co-added image. The\nmidtime of the co-added image (39x120 s) is Apr. 29.820. Due to short focal length \nof AT-64 (F=900mm, F/1.4)  the OT appears to be in the wing of the star\n\nUSNO A2.0  675-11945727\nRA =12 13 07.92\nDEC=-20 54 45.3\nR=17.90  B=20.50\n\nStar 1 in the image at\nhttp://grb.rssi.ru/GRB030429/030429_030429_at64.gif\n\nThe limiting magnitude of the  image calibrated with USNO A2.0 catalog\nR-band is 20.7, so we can estimate the OT magnitude as brighter as R=20.7m.\nOur estimation is consistent with OT decay slope 2 which implies the\nobservation by  A.Gilmore at al. (GCN 2184).\n\nDetailed calibration and PSF analysis is in a progress.",
