Hα and Hβ Photoelectric Photometry of γ Cassiopeiae.

Photoelectric observations of γ Cas (B0 IVe) were made using two pairs of wide- and narrow-band interference filters centered enar the rest wavelengths of the hydrogen Balmer α and β lines. Hα and Hβ indices were obtained on 19 nights from February 1972 to February 1975. Variations in the Hα and Hβ indices were found with a range of 0^m 18 and 0^m 10, respectively.
