DAE 2 NLTT 15049 = LP 717-36. Daemgen et al. (2007) derive a distance of Dae2007
20.2 +/- 4.7 pc, a separation of 10.9 +/- 2.5 au, and a predicted
orbital period of 58 +/- 21 yr. Spectral types are M3.5 +/- 0.5 and
M4.0 +/- 0.5; masses are 0.36 +/- 0.09 and 0.28 +0.11/-0.08 Msun.
Parallax = 49.07 +/- 1.40 mas. Possible member of the AB Dor moving JLB2017
group.
