It was measured 4*47 by Pierce {Harvard Annals, vol. ix.). He 

 says, "The disagreement of different observers in reference to the 

 relative brightness of 9 and A Eootse is noticeable. On July 27, 1875, 

 at Munich, I found 6 much the brighter." On August 28, 1875, I 

 found 6=K Bootis, both slightly brighter than i Bootis ; February 19, 

 1884, I estimated 6 two steps brighter than X, 3^- steps biighter than 

 K, and six steps brighter than i Bootis ; March 14 ^ six steps brighter 

 than K.

 ham's estimates of magnitude 1872-1876 vary from 6 to 7. March 12, 

 1880, I found it about four and a-half steps less than a star np 

 (LL 26634), but brighter than LL 26851 ; March 15, 1884, six: steps 

 brighter than the star np, and about 6^ m.

July, 1875, I found ir about = f Bootis (5-4 Heis). 



April, 1876, TT slightly brighter than f.

March 22, 1884, tt one step less than o, or 4'6 m. 



April 1, 1884, TT one step less than o, or 4*6 ; April 6, 4-6.

 (1882-370). It is a close double star (Doberck 299°.8 : 1", 1877). 

 Smyth says {Bedford Catalogue, p. 324) : " B, 4J, bluish white, and 

 supposed to be variable." Struve and Secchi considered the compo- 

 nents to be alternately variable. 3-84 and 3-9 H.P.

 rejected by Schonfeld.

 Closely sf. is a 9 m. star, Lalande 26786. 



April 6, 1884, I estimated it 5-0 — rtwo steps brighter than
