Scientific paper

The paper discusses the photographs made in the vicinity of the earth-moon triangular libration points L4 and L5, and of the solar-synchronized positions in the associated halo orbits. The photographs were taken in Aug.-Sept. 1979, using the 30-in. Cassegrain telescope at Leuschner Observatory, Calif. An effective 2 deg square field was covered at each position; each exposure was examined with a microfiche reader with two magnification levels. The entire 1 deg photographic field was divided into 288 search squares and each was visually scanned for the expected double image of a libration-halo object; the results were all negative. Several calibration exposures of M15 were taken by tracking at the sederial rate without a guide star to simulate the effects of imperfect guiding on libration/halo objects. It was concluded that no ancient spacecraft or other object of reflectivity greater than lunar albedo, having the size of Skylab or larger is parked at L4, L5, or in any of the predicted halo orbits in the earth-moon system.
