This star is described in Sir W. Herschel’s Catalogue of 
1785 as of the 6th class, on account of a small star near, but 
was afterwards observed by him, as also by Messrs. Bessel, 
Struve, Pond, and South, to be double of the first class. 
M. Amici has also noticed the close star, and measured its 
distance, which he states at i" (Zach, Corresp. Astron. viii. 
page 222 ) but this is probably too small.
