discov_num notes refcode
HJ 898 Doolittle notes a 3rd star in the direction of B. 30" +/- distant, Doo1932A
12th magnitude, 1919.8.
CPM of the components suggests that this pair could be physical;
however, since the relative motion of the components is larger than
their proper motion, the question of whether they are physically bound
remains open. Kiy2012
