discov_num notes refcode
BLM 3 Aa,Ab: gam Boo = 27 Boo = Seginus. A is a Delta Scuti-type system.
1975.383: Photometric variable star of tentative period 0.29 day;
also a member of a binary system with separation ~33".4 and delta m
~ 9.27. This observation apparently resolves the brighter primary into
two stars. BLM1978
BU 616 AB: Optical pair, based on study of relative motion of the
components using the method of apparent motion parameters. Kiy2008
