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

The coronal structure overlying, and presumably associated with, an isolated active region, McMath 12686, is identified during its west limb passage 15-17 January 1974. The region had a 'flaring site' on its border close to a plage filament and exhibited various forms of activity, including type III
The temperature and density structure of a 'typical' coronal active region is deduced from X-ray observations of several active regions. Observations of the limb transits of three regions from OSO-5 indicate that the X-ray emission originates between 2 x 104 km and 1.5 β’ 105 km. An emission measure-
