KAPPA CAS (Kappa Cassiopeiae). Cassiopeia, the Queen, is recognized by two obvious configurations, the first her famed "W," made (from west to east) of Caph (Beta Cas), Shedar (Alpha), Gamma, Ruchbah (Delta), and Epsilon.

Some fifteen supergiants are members of this group (including kappa Cas). The period ranges from five to ten days and the amplitude is less than 0.1 magnitude. For alpha Cygni, the range is 1.21 to 1.29.
