discov_num notes refcode
DUN 99 B is CPD-70@1185, spectrum A6IV.
CHR 227 Ba. Worley (private communication) noted that the systematic binary
star surveys of Rossiter (1955) and van den Bos missed the Rst1955
declination band -73 to -70 deg. This probably explains why this
half-arcsecond pair remained undiscovered until now. CHR 227
represents a new component to the wide (63") common proper motion pair
HR 4211-12 = DUN 99 AB, discovered by J. Dunlap in 1826 (1829) and Dun1829
last observed nearly 80 years ago (Dawson 1918). A 10th magnitude C Daw1918a
component also lies some 35" from A, discovered by John Herschel in HJ_1847a
1835, but no closer components are known. Hrt1996b
