Leibowitz \n(Wise observatory, TAU) report:\n\nWe are observing the OT of GRB 030329 (Peterson & Price, GCN 1985) \nusing the Wise observatory 1m telescope + SITe CCD camera, starting \nMarch 29, 17:15 UT (5.6 hours after the burst). Large number \nof 300 s B, 120 s V and 120 s R-band frames are being obtained under \nhighly variable conditions, with passing clouds.\n\nWe detect the OT on numerous B, V and R-band images. A rough calibration\nusing nearby bright USNO A-1 stars gives R~14.3 and B~15 for the OT. We\ncan also estimate the decline rate to be about 0.3 mag/hour in the R-band,\nfrom the first two hours of data. Further data acquisition and analysis \nare underway.",
