1922 Zulu (1949 HC) is an outer main-belt asteroid discovered on April 25, 1949 by Ernest Leonard Johnson at Johannesburg (UO).[1] It is one of very few asteroids located in the 2 : 1 mean motion resonance with Jupiter.[5] This asteroid was lost shortly after discovery (see Lost asteroid), and only rediscovered in 1974 by Richard Eugene McCrosky, Cheng-yuan Shao and JH Bulger based on a predicted position by C. M. Bardwell of the Cincinnati Observatory.[6]
