Scientific paper

Observations of a 10-arcsec-wide 800-arcsec-long region of the southern solar hemisphere, obtained at 150-160 nm by the rocket-borne High-Resolution Telescope and Spectrograph on March 1, 1979, are reported and analyzed. Rastered stigmatic spectra are reduced to create color images of intensity, Doppler shift, and line width providing information on the UV structure of the solar atmosphere. Characteristics discussed include temperature stratification in quiet-sun network elements; chromospheric jets appearing at supergranular cell centers; general redshift of 5 km/s in quiet-sun C IV; downflow patterns in C IV, Fe II, and C I; plage structures with temperature stratification and 6-km/s C IV downflow; and faint filament emission with blueshifts near the top and redshifts at the sides in the C IV images.
