We present preliminary results from BRITE and MOST photometry of a subset of 8 Wolf-Rayet stars. After allowing for any known periodic variations in binaries, we found only stochastic light variations, for which time-frequency and wavelet analyses reveal an average life-time of around 10 days, with frequencies ranging from 0.05 to 0.5 cycles/day.
