Özet
A total of 156 hr of data in the V and B band were obtained in a two-site campaign which lasted 17 days in 1994 September-October. Frequency analysis was carried out carefully on these data and five frequencies, f(1)=3.617, f(2)=3.655, f(3)=4.286, f(4)=2.385, and f(5)=5.847 c/d are derived from both the V and B data. The variation behaviors in the U band also agree with these five frequencies. Mode identification shows that the first four frequencies can be best interpreted with the degeneracy of frequencies due to the star rotation. f(1), f(2), f(3), and f(4) are identified with m=-2, 1, -1, and 2. In addition, some interesting problems are discussed. (C) 1995 American Astronomical Society.
