Antipov\n\nSternberg Astronomical Institute, Alexsandr Krylov Observatory, Moscow\n\nreport:\n\nThe OT of GRB030329 (Peterson and Price, GCN 1985) was observed with\nMASTER system (280mm, http://observ.pereplet.ru, GCN 2002). We obtained\nabout 200 measurements in R filter, with calibration to several tens of\nUSNO A2.0 stars located in 15 arcmin field around the OT. Our\nobservations started at Mar 29, 17.1 UT (5.5 hours after the GRB) and had\nbeen lasting for 8.5 hours up to Mar 30, 1.5 UT (13.9 hours after the GRB).\n\nCorresponding to our observations, R-band flux declines as t^-1.0 (sligtly\ndiffers from t^-1.1 reported by Burenin et al. GCN 2024). At the end of\nobservations the OT's brightness began to decrease more rapidly. We had\nvery poor transparancy at that time, so flux measurements uncertanities\nwere quite big, therefore we can't confirm or refute -1.9 index reported\nby Garnavich et al. (GCN 2018).\n\nOur lightcurve based on 114 measurements available at:\nhttp://observ.pereplet.ru/images/GRB030329_R_lc.gif\nhttp://www.sai.msu.su/~chil/GRB030329_R_lc.ps\n\nFurther analysis of the obtained data is underway.\n\nThis message may be cited.",
