摘要:
AbstractThis satellite was first seen briefly in Nairobi at the end of December 1960. By the end of January 1961 rough times for two successive passages had made identification possible, and by March 1961 predictions for its reappearance derived from the orbital elements computed according to the routine described in this paper were working reasonably well. Repeated observations have improved both the methods used and the results obtained from them.
