Paper Abstract

The high resolution X-ray observations from Skylab provide a view of the structure and evolution of the solar corona. The S-054. X-ray telescope operated successfully. throughout the eight month mission, photo-graphically recording nearly 35,000 images. The telescope is a grazing incidence instru ment (Ref. 1) with spatial resolution of the order of two arc seconds on axis. The total, wavelength range observed by the instrument. is 2 - 60 R.. Crude spectral resolution within this range is achieved by means of a series of six X-ray filter materials. A spectrographic mode of operation, which employs an objective grating, is used to obtain spectra of flare events and selected coronal features. The images produced by the telescope are recorded on film.
