Re: [Utah-astronomy] RASC Colorful Doubles (N=79) to SAO Cross-reference list
Erik, That's lambda Ari. The Belmont Society list describes lambda Ari as "yellow/purple/yellow/blue". http://simbad.u-strasbg.fr/simbad/sim-basic?Ident=lam+Ari The list is intended to be stars that have an easily perceived color contrast. gam Ari is not a color contrast star. The Astro League double star list describes it as "white-white"; the Belmont Society Double Star list as "bluish-white/white". eps Ari was not on the source RASC Observer's Guide List, but it is on the Belmont Colorful Doubles List as non-contrasting "white-white". The perceptual differences can all be discounted as observer variations. Clear Skies and Warmer Nights - Kurt
Ok, Haas lists that as 41 Ari, also Haas quotes Smyth on epsilon Ari as yellow/white.
