Sakhibullin, V. Suleymanov (KSU)\nreport:\n\nError box of GRB030329 (HETE Trigger #2652) was observed with 1.5-m\nRussian-Turkish Telescope RTT150 at Bakyrlytepe (TUBITAK National\nObservatory, Turkey) started at Mar 29.744 UT, appr. 6 hours after the burst.\n\nWe confirm the presence of the optical transient (OT) reported by Peterson\nand Price (GCN 1985). In the beginning of our run the afterglow appear to\nhave the following magnitudes: B=14.99, V=14.46, R=14.12, I=13.60, and is\nfading at a rate appr. 0.18 mag per hour in every filter. At 29.794 the OT\nhas magnitudes: B=15.19, V=14.65, R=14.34, I=13.82. We will continue our\nobservations as long as it will be possible.\n\nThe absolute fluxes will be calibrated more accurately. The light curves\nwill follow.\n\nThis message may be cited.",
