FIN 340 AB. 1991.3926: From its discovery in 1954 through the mid-1960's, this
system closed from 0".14 to 0".10 and increased in theta from 147 deg
to 172 deg. It is impossible to determine from this single speckle
measure whether the pair has gone through periastron and flipped
quadrant, but this should become obvious within the next couple of
observations.
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 3.37 +/- 0.76, 4.60, and 2.40 Msun, respectively. Mlk2012
