FIN 317 Aa,Ab: FIN 317 is a close subsystem in the 2.9" AB pair HJ 4188. After
discovery of Aa,Ab in 1951 at 0.116", Finsen (1951) was unable to Fin1951b
resolve the star again on twelve occasions till 1968, except one other
tentative measure in 1962. Yet the object was resolved by speckle in Fin1964a
1989.94 at 0.144" and in 2006.18 at 0.123". Despite orbital period of
∼50 yr estimated from projected separation, the sub-system was not
detected in 3 runs at SOAR (2009-2012), while the wider pair AB was
measured. This may be yet another case of erratic measures and
non-resolutions. Possibly another "ghost" which isn't a real binary, Tok2012b
but not "X" coded yet.
