HDS1260 AB + TOK 395: Like WDS 08021-1710, the late-type nearby binary HDS
1260 was discovered by Hipparcos and is expected to move rapidly (HIP
42910, BD-20 2665). It was targeted at SOAR for the first time. To our
surprise, the object turned out to be a resolved triple, with the
secondary being a 0".16 pair of equal stars. Hipparcos failed to
recognize the triple nature of this star. The estimated period of BC
is 15yr. The outer pair AB has closed from 0".8 to 0".5 and moved in
position angle since its discovery. The separations between components
are comparable, so this triple system may be interesting dynamically. Tok2015c
