Description:
The Goddard Space Flight Center instrument carried on the pointed section of the OSO-7 satellite is described. This instrument contains: an extreme-ultraviolet spectroheliograph using glancing incidence optics of Wolter's Type II to focus the sun's light on the entrance slit of a concave grating spectrometer; an auxiliary H-alpha system; two X-ray spectroheliographs using mechanical collimators for spatial resolution and Ross filters to isolate spectral bands of interest; and a flare polarimeter operating in the 15-40 keV X-ray region. The subsystems may be operated in a number of modes which, when combined with the spacecraft modes, give the instrument great flexibility for making solar observations. Representative results from each of the subsystems are presented.
