An ultraviolet spectral Atlas of a sunspot with high spectral
and spatial resolution in the wavelength region 1190 - 1730 A is
presented. The sunspot was observed with the High Resolution
Telescope and Spectrograph (HRTS). The HRTS instrument was built
at the U.S. Naval Research Laboratory (NRL), Washington, D.C.
(Bartoe and Brueckner, 1975). The instrument combines high
spatial, spectral, and ... time resolution with an extensive
wavelength and angular coverage. This makes HRTS particularly
well suited for studies of fine structure and mass flows in the
upper solar atmosphere. HRTS has flown six times on rockets
between 1975 and 1989 and as a part of Spacelab 2 in 1985. The
spectrograms used for the Atlas are from the second HRTS rocket
flight, known as HRTS II, flown on 13 February 1978 aboard a
Black Brant VC rocket (NASA Flight 21.042) at White Sands, New
Mexico. During the rocket flight the slit was oriented radially
from the solar disc center through the active region McMath
