✦ Synopsis

Polar plumes have been detected in X-rays with the Skylab S-054 experiment. Observations of one well observed plume are analyzed and the plasma pressure is determined. An isothermal model in hydrostatic equilibrium is found to require unacceptably low temperatures. A hydrodynamic model is proposed which is consistent with earlier white light and EUV observations. Calculations indicate that the total outward mass ftux in polar plumes is comparable to that in high speed solar wind streams expected from a polar coronal hole.

Three polar plumes were studied using Sk}lab Mg x and O \q data. The plulues lie within the boundaries of a polar coronal hole. We find that the mean temperature of the plumes is about I.J x 1() r' K and that they have a small xertical temperature gradient. Densities are determined and found consist
