Near-synchronous uncontrolled objects were searched using an optical telescope. The observation was planned systematically. The geostationary orbit was scanned in two nights so as to follow a definite right ascension. Seven drifting objects were detected. These orbits were estimated since a fixed point was observed in the equatorial celestial coordinates. Therefore, follow-up observation is easy even if these are not tracked constantly. As a result, the proper orbits of four objects were determined. The observation procedure is appropriate for parallel measurement of near-synchronous debris.
