DAE 7	NLTT 56566 LP 642-48
	Daemgen et al. (2007) derive a distance of 22.6 +/- 6.7 pc, separation	Dae2007
	of 2.2 +/- 0.7 au, and predicted orbital period of 6 +/- 3 yr.
	Spectral types for both stars are M4.0 +/- 0.5; masses are
	0.25 +0.18/-0.11 and 0.21 +0.17/-0.09 Msun.
	Although the close binarity of 2MASS J23205766-0147373 was reported in
	Daemgen et al (2007) and our AstraLux data have a similar sensitivity,	Dae2007
	the star appears single in our images. Since the separation was only
	99 mas in 2005, it has presumably moved inward since then.	Jnn2012
