dc.description.abstract	The Sr-Cr type chemically peculiar star HD 42536 (= HR 2195) was observed with the 2.34 meter Vainu Bappu Telescope. Kavalur during the period of November 1998 to April 1999. A total of 46 spectrograms were obtained in the wavelength region of 3900 Å to 4300 Å at a linear dispersion of 0.65 Å per pixel. The equivalent widths of Sr (4077) and Cr (4172) have been found to be varying with a period of 0.58 ± 0.02 day, the amplitudes being about 100 mÅ and 60 mÅ respectively. This period is a resonance value of the peroid given by Manfroid and Mathys (1985).	en
