BU 720 Variable? Egg1947
Only elements P and T have been amended by Starikova (1982) from the Sta1982b
orbit of Baize (1976). Baz1976
Elements published for this long-period system differ: Costa (1966
Urania, Barcelona 51, 73) quotes P = 198.6 yr, while Tel'nyuk-Adamchuk TkA1966
gives P = 425 yr. The observed theta and rho for 1975.953 are in
reasonable agreement with either uncertain orbit. BLM1978
See Baize & Petit (1989) catalog of doubles with variable component. Baz1989d
