JNN 126 LP 636-19.
The M3.0 equal-flux binary was first resolved by Janson et al. (2012), Jnn2012
and has seen significant orbital motion. Its parallactic distance of
37.9 +/- 5.7 pc (Shkolnik et al. 2012 ApJ 758, 56) implies a physical
separation of ~3-5 au. The expected orbital period is 10-20y. Bwl2015
