STF 115 First measured by F.W. Struve in 1836 at an angular separation of Hrt1989
0".68, this system had opened to 1".2 by 1910, then steadily closed
to 0".35 at the time of the first speckle measurement in 1978.
The pair reached an apparent minimum separation of 0".01 in the
spring of 1984.
1983.7107 This autocorrelogram was remeasured; the new results are
listed in the catalog.
AB: Malkov et al. (2012) derive dynamical, photometric, and
spectroscopic masses 2.36 +/- 0.67, 2.80, and 1.20 Msun, respectively. Mlk2012
