Date & Time: 14 January 2001( 23:00 UT )  
Seeing: 6  <1-10 Seeing Scale (10 best)>  
Location of site: Cheshire. UK 
53° 15' N –2º 33' W  
Site classification: Suburban  
Sky darkness: 3-4 <Limiting magnitude>  
Conditions: Clear and cold with drifting high haze. 
Telescope: 200mm f/6  Newtonian scope  mounted 
over a Vixen GP mount (manual slow motion). 
Any Quoted PA or SEP using Celestron micro guide (CMG ) 
Magnification: X60 
 
This double star was a nice system to observe using a magnification of X60. The colour of the primary star appeared to be yellow with the secondary a delicate pale blue. 
 
I estimated to PA of the secondary to be at about 90deg.( following edge of primary)
