CHE 27	This pair has opened considerably since its discovery (from 9".6 to	Che1910
	19"), due to the considerable proper motion of the primary. AC2000
	coordinates of both components from ~1901 are in good agreement with
	Chevalier measure, so identification with this pair appears probable.	Hrt2012b
