Summary
The spectra of nearly 100 samples of Bpc3 pulsations were computed in the X and Y components of data from the Budkov Observatory. These spectra were used to study the daily variations of the fundamental characteristics of the pulsations, the frequency f0 and amplitude A0 of the main spectral peaks. The daily variation of the ellipticity of the polarization ellipses of oscillations in frequency f0 was also studied in the XY-plane.
