V = 5.9;  Size 7

17.5": 20 stars mag 7.5-13 in bright, distinctive group.  Fairly small, about 6' 
diameter, not rich.  The stars are divided into two main subgroups - along the 
west side is a string of six stars aligned N-S in a very shallow "V" asterism.  
The northern two stars in this string form the wide double ?844 = 8.8/9.9 at 24" 
and less than 2' S is mag 8.7 SAO 95271.  The eastern subgroup consists of 9 
stars forming a distinctive triangle outline and includes the close double star 
?848 = 7.5/8.0 at 2.5".  The brighter stars form a fairly distinctive "37" 
pattern!  Located 0.9 degrees WSW of Xi Orionis.
