Abstract: The chemically peculiar star HD 115735 (= HR 5023 = 21 CVn) was observed with the 2.34 meter Vainu Bappu Telescope at Kavalur during the period of January 1999 to April 2000. A total of 47 spectrograms were obtained in the wavelength region of 3900 º to 4400 º at a resolution of 0.65 per pixel. The equivalent widths of Si II features at 4077, 4128, 4131 have been found to be varying with a period of 0.88 +/- 0.02 day, the amplitudes being about 0.1º. This is the ¯first report of spectroscopic variations of these features in this star
