Lepus 8

α, Double, 2.7 and 9.5, pale yellow and gray.

Arneb is from the Arabian name for the whole, but the Century Dictionary substitutes the early Rash.
Other near-by stars, presumably in Lepus, were the Chinese Kuen Tsing, an Army Well, and Ping Sing, the Star Screen.
Arneb culminates on the 24th of January.
The components are 35ʺ.4 apart, at a position angle of 156°; and 6ʹ away is Sir John Herschel's 3780, a sextuple star.

β, Double, 3.5 and 11, deep yellow and blue.

Nihal is from the collective title of α, β, γ, and δ, — Nibal with Burritt.
Holden says that the companion, nearly 3ʺ away, at a position angle of 292°, is suspected to be a planet; and Burnham has discovered other faint companions.
The variable R, 6th to 8.5 magnitudes, is Hind's Crimson Star, discovered by Mr. J. R. Hind in 1845, — "like a drop of blood on a black field." It lies in front of the Hare's head, on the border of Eridanus, but its discoverer announced it as in Orion. Its variability, in a very irregular period of about 438 days, was first recorded by Schmidt in 1855, but accurate observations of maxima and minima are difficult in high latitudes.
