ABSTRACT
We observed Nova Cir 1995 and Nova Aql 1995 with the Hopkins Ultraviolet
Telescope during the Astro­2 space shuttle mission in 1995 March. The spectra
cover the wavelength range from 820 š A to 1840 š A with a spectral resolution of
about 3 š A, extending the ultraviolet wavelength coverage of novae to the region
between Ly ff and the Lyman limit for the first time. The Nova Cir spectrum
contains many broad carbon, nitrogen, and oxygen emission lines thoughout
the HUT wavelength range. We approximate its extinction, and fit absorption
by the Lyman and Werner bands of molecular hydrogen to find an H 2 column
