Scientific paper

An observational search for short-period comets with perihelion distances in excess of 4 AU is discussed which was performed to a limiting V magnitude of about 18. A total of nine unidentified moving objects with apparent V magnitudes of 16 to 18 were discovered; daily motions, inclinations, and orbital radii are estimated for these objects. One of the objects is found to exhibit a motion which could be expected from a short-period comet with a large perihelion distance. It is noted that the orbital radius estimated for this object suggests a Trojan asteroid, but the daily mean motion could also correspond to a high-eccentricity orbit with aphelion beyond the orbit of Saturn.
