Periodic Doppler width fluctuations have been observed in Fe xIv spectra above an active region. The oscillations have a period of 6.1 β’ 0.6 min and a peak-to-peak amplitude of 0.07 + 0.006/~. The amplitude of the oscillation increases with height above the limb, and is enhanced at specific heights
