Wavelet analysis has been performed on the American Association of Variable Star Observers (AAVSO) visual estimates of the RV Tauri star U Mon from 1961-2000 using the AAVSO WWZ wavelet analysis program. Periods of 46.07, 92.40 and 2498 days are present but the 92 day period is not always detectable. A constant ratio between the amplitudes of the 46 and 92 day periods is found during one single long-term deep minimum but not another.
