RY Lep is a long-period High Amplitude Delta Sct-type pulsator (V=8.21, DeltaV=0.35) with a main period of 0.2254d (Diethelm 1985). This star was assumed to be monoperiodic with stable light curves for a long time. However, some disturbances have recently been discovered by Laney et al. (2002). New observations were collected at Sierra Nevada Observatory (SNO), Spain, with simultaneous uvby photometry, from 1998 to 2002, but only the two data sets collected in 1998 and 2002 are good enough to perform individual Fourier analyses. Additional VJHK data were collected at South African Astronomical Observatory (SAAO), South Africa, during the same epoch.
