This star is part of the Sirius group and is an Alpha CVn variable.
B has an extremely close companion at 0.4 @ 66. The orbit takes 57 years with a
semi-major axis of 0.27" and direct motion.
Observations:
C8 at 104x. Use averted vision to see the companions.

Rating: 2 E
Position: 1647+4730
Type : Gc
Dimensions: 4'
Class: 4
Magnitude : 8.7
Notes:
William Herschel classified it as a planetary by mistake.
The brightest stars are 15.5m and the horizontal branch is 18.0m.
Observations:
C8 at 65x. Small and bright; high power does not help the view. Two 8m stars form
an isosceles triangle with it.
C11 at 115x. It forms the acute angle of an isosceles triangle with two 9m stars. It
rapidly brightens to the center, but looks assymmetric. It is mottled at 193x, and outliers
are picked up at 339x.
Model (where the Sun is a baseball):
Its diameter would be 30,700 miles.
