MV Sgr is a hot, hydrogen-deficient star which has undergone R CrB fadings. We have used self-correlation analysis and Fourier analysis of CCD V-band photometry in the AAVSO International Database to identify a period of 8.0 days in this star; the amplitude is about 0.03 magnitude. The variability is most likely due to pulsation.
