WDS 20035+3601 MCA 59 Aa,Ab : NOTES
 
 
discov_num notes refcode
MCA 59 The Aa,Ab pair has been resolved in only 4 of 11 observations, and
STF2624 the positions are discrepant (the large errors presumably result from
a large magnitude difference). The B and C components were also
observed and appeared to be single. Msn1998a
Classification of B and C components are from Hoffleit et al. (1983). Hof1983
Both A and B are SBs, and there is a small light variation.
AB: H 1 96. MEv2010
