摘要	Using periodograms for unequally spaced data and convergent least squares, 177 differential photoelectric V band measurements of the newly discovered delta-Scuti variable HD 93044 during three nights have been analyzed. After resampling the data in equal intervals to check the results using periodograms for equally spaced data, three frequencies: 11.38927, 2.1426 and 22.49097 cycle d-1 are identified in the data set. The frequencies of 11.38927 and 22.49097 cycle d-1 indicate that the observed variability of HD 93044 is due to radial pulsation of delta-Scuti type in the fundamental and third overtone modes. The frequency of 2.1426 cycle d-1 is tentatively attributed to an atmospheric extinction effect.
