TOK 292 HIP 66676 (A) and HD 118735 (B, G6V, V=9.17) at 77" share common PM
(although it is small, 58mas/y) which, together with photometry,
indicates with high probability that it is a physical pair AB
(Tokovinin & Lepine 2012). We targeted the secondary component B and Tok2015c
found it to be a resolved triple. The faint star C, at 0".92 from B,
is itself a close 0".16 pair Ca,Cb. Note that this is a region of the
sky with very high stellar density, raising suspicion that the Ca,Cb
pair might be a random background object. Re-observation of the triple
in 2015 (to be published) shows, however, that it is physical because
the center of C=(Ca,Cb) moves relative to B with a speed of 11mas/y
(or 3km/s), compatible with the expected orbital motion of BC and much
less than the system's PM of 58mas/y. The estimated period of Ca,Cb is
~30 years, the period of BC is ~300 years. Tok2015c
