SNA 72 The primary is V1081 Sco, a detached Algol-type eclipsing binary
showing apsidal motion (Otero 2005, IBVS 5631, 1), most probably
because of this third component at 26.8mas. The object is reported as
SB3 and we postulate our detection corresponds to the 3rd component. Sna2014
HD 158186 The classification is from Garrison et al. (1977 ApJS 35, 111). An
eclipsing light curve is presented in the Hipparcos Catalogue for a HIP1997a
for a period of 8.77 d. Msn1998a
